5) Cancel 3.
10 = 10
Draw a figure composed of three different rectangle that has a perimeter of 140 yards use measurements in yards in feet to label this side of your figures.
To create a figure of three rectangles with a perimeter of 140 yards, you can stack them on top of each other to make a plus sign, and label each side as 11 and 2/3 yards or 11 yards (by subtracting the fractions).
What is rectangle?A rectangle is a four-sided geometric shape that has four right angles (90 degree angles) and opposite sides that are parallel and of equal length. The length of a rectangle is its longer side, while the width is its shorter side.
According to given information:If we draw three rectangles stacked on top of each other like a plus sign, we can divide the perimeter of 140 yards by the number of sides, which is 12. This gives us a length of 11 and 2/3 yards per side.
To use only integers, we can subtract the fractions from each side to another, which gives us a length of 11 yards per side. We can then label each side of the figure with a length of 11 yards.
In the figure, we have three rectangles of equal size, with a length of 11 yards and a width of 35 yards. We can convert the measurements to feet by multiplying by 3, which gives us a length of 33 feet and a width of 105 feet.
Alternatively, if we wanted to use only whole numbers, we could increase the size of each rectangle slightly, so that the total perimeter is a multiple of 12. For example, we could make each rectangle 11.6667 yards by 35 yards, which gives us a total perimeter of 140.0008 yards. We can then divide this by 12 to get a length of 11 and 2/3 yards per side, and label each side with a length of 11 yards.

a pair of headphones originally costs 95$ and is on sale for 70$ what is the percent change in the price of the headphones? be sure to show whether it is a percent increase or decrease.
The percent decrease in the price of the headphones is 26.32%.
Explanation:
To find the percent change in price, we can use the following formula:
percent change = (new value - old value) / old value * 100%
In this case, the old value is the original price of the headphones, which is $95.
The new value is the sale price, which is $70. Plugging these values into the formula, we get:percent change = (70 - 95) / 95 * 100%
percent change = -25 / 95 * 100%
percent change = -0.2632 * 100%
percent change = -26.32%
The negative sign indicates that the price has decreased, and the magnitude of the percent change is 26.32%, which means that the sale price is 26.32% lower than the original price.
If 250 divided in the ratio 3:7,then smaller part is 25
If 250 is divided in the ratio 3:7, then 75 is the smaller part. To find the smaller part of 250 divided in the ratio 3:7, you need to first find the total number of parts that the ratio represents.
The total number of parts in the ratio of 3:7 is 3+7=10.
Next, you need to find the value of one part.
To do this, divide the total amount by the total number of parts:
250 ÷ 10 = 25
This means that one part of the ratio is equal to 25.
To find the smaller part, you need to multiply the value of one part (25) by the ratio of 3/10 (which represents the smaller part of the total).
So the smaller part is:
3/10 x 250 = 75
Therefore, the smaller part of 250 divided in the ratio of 3:7 is 75.

Answer:
If x = 3 and y = 2.3^3, then we can evaluate y using exponents:
y = 2.3^3 = 2.3 × 2.3 × 2.3 = 12.167
So, y = 12.167 when x = 3.
Next, if we want to solve the equation y = 2[?] using order of operations, we need to evaluate what is inside the brackets first. We know that y = 12.167, so we can substitute that value into the equation:
y = 2[?]
12.167 = 2[?]
To solve for the missing value inside the brackets, we need to divide both sides by 2:
12.167 ÷ 2 = ?
6.0835 = ?
Therefore, the solution is y = 2(6.0835), or y = 12.167, which we already found earlier.

where c is the length οf the hypοtenuse, and a and b are the lengths οf the οther twο sides (alsο knοwn as the legs) οf the right-angled triangle.
In this case, the tοwer, the grοund, and the guy wire fοrm a right triangle. We knοw the height οf the tοwer is 45 ft, and the hοrizοntal distance frοm the base οf the tοwer tο where the guy wire is secured tο the grοund is 28 ft. Let's call the length οf the guy wire c. Then, we have:
a = 28 ft (hοrizοntal distance frοm the base οf the tοwer tο where the guy wire is secured)
b = 45 ft (height οf the tοwer)
c = length οf the guy wire (hypοtenuse)
Using the Pythagοrean theοrem, we can sοlve fοr c:
[tex]a^2 + b^2 = c^2[/tex]
[tex]28^2 + 45^2 = c^2[/tex]
[tex]784 + 2025 = c^2[/tex]

If a client who weighs 207 lb (94.1 kg) is to receive 1.5 mg/kg of gentamicin sulfate iv three times each day, the nurse should administer 141 mg of gentamicin sulfate for each dose.
To calculate the dose of gentamicin sulfate that the nurse should administer to the client, we need to know the client's weight and the desired dosage, which in this case is 1.5 mg/kg.
First, we need to convert the client's weight from pounds to kilograms. To do this, we divide the client's weight in pounds by 2.205 to get the weight in kilograms:
207 lb ÷ 2.205 = 94.1 kg
Now that we have the client's weight in kilograms, we can calculate the dose of gentamicin sulfate for each administration:
1.5 mg/kg × 94.1 kg = 141.15 mg
We round 141.15 mg to the nearest whole number, which is 141 mg.

When we say that liquid water is unstable on Mars, we mean that
Therefore, liquid water is considered to be unstable on Mars due to the cold temperatures, low atmospheric pressure, and the UV radiation. All of these environmental factors make it difficult for liquid water to persist.
Liquid water is unstable on Mars due to its cold, dry environment. Because the atmospheric pressure is too low to hold liquid water, the water on Mars quickly evaporates, sublimates, and/or is broken down by the ultraviolet radiation in the atmosphere.
The average temperature of the surface of Mars is −63 °C, which is well below the freezing point of water. Because of this, liquid water cannot exist on the surface of Mars. When temperatures are slightly higher, water can exist as a liquid, but it cannot stay in this state for very long.
The atmosphere on Mars also does not contain enough pressure to sustain liquid water. Even when water vapor is present, it will quickly evaporate in the low-pressure environment. Additionally, the UV radiation in the Martian atmosphere will break down water molecules quickly.

in a large population, 64% of the people have been vaccinated. if 3 people are randomly selected, what is the probability that at least one of them has been vaccinated?
The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.
The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated can be calculated using the binomial probability formula.
The binomial probability formula is used to calculate the probability of a given number of successes from a given number of trials when the probability of success is constant. In this case, the number of trials is 3 (i.e. the three randomly selected people) and the probability of success is 64% (i.e. the probability that each of the randomly selected people has been vaccinated).
To calculate the probability that at least one of the three randomly selected people has been vaccinated, we first calculate the probability of none of them having been vaccinated:
P(none) = (1 - 0.64)^3 = 0.216
Then, the probability of at least one of them having been vaccinated is 1 - P(none) = 1 - 0.216 = 0.784.
In conclusion, the probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.

That is, b = 6.
now, to find what results only in a horizontal compression of y = b * y by a factor of 6.

the volume of the right cone below is 392\piπ units^3 3 . Find the value of xx.
The value of x is approximately 8.15.
To find the value of x, we need to use the formula for the volume of a cone, which is V = (1/3)πr^2h, where r is the
radius of the base and h is the height of the cone. We know that the volume of the cone below is 392π, so we can set
up the equation:
[tex]392π = (1/3)πx^2h[/tex]
Simplifying, we can divide both sides by π and multiply by 3 to get:
[tex]1176 = x^2h[/tex]
Using the Pythagorean theorem, we can relate the height, radius, and slant height of the cone:
[tex]h^2 + r^2 = x^2[/tex]
Since the cone is a right cone, we know that the radius is half of the diameter, which is equal to x/2. Substituting this in,
we get:
[tex]h^2 + (x/2)^2 = x^2[/tex]
Simplifying:
[tex]h^2 = x^2 - (x/2)^2
h^2 = 3x^2/4[/tex]
Now we can substitute this expression for [tex]h^2[/tex] into our equation for the volume:
[tex]1176 = x^2(3x^2/4)[/tex]
Simplifying again:
[tex]1176 = 3x^4/4[/tex]
[tex]1568 = 3x^4[/tex]
[tex]x^4 = 1568/3[/tex]
Taking the fourth root of both sides:

ten percent of computer parts produced by a certain supplier are defective. what is the probability that a sample of 10 parts contains more than 3 defective ones?
The probability of a sample of 10 parts containing more than 3 defective ones is approximately 0.026.
We can use the binomial distribution to calculate the probability of getting more than 3 defective parts in a sample of 10 parts. Let X be the number of defective parts in the sample. Then X follows a binomial distribution with parameters n=10 and p=0.1, where n is the sample size and p is the probability of a part being defective.
We can calculate the probability of getting more than 3 defective parts is:
P(X > 3) = 1 - P(X ≤ 3) = 1 - [P(X=0) + P(X=1) + P(X=2) + P(X=3)]
Next, we can find that:
P(X > 3) = 0.026
Therefore, the probability of a sample of 10 parts containing more than 3 defective ones is approximately 0.026.

if y varies directly as x, and y=7 when x=3, find when x=7
By definition, direct variation takes the following form:
y=kx
Where k is the proportionality constant.
You can find k given the information in the problem:
7=3k
k=3/7
You can now find y when x=7 as follows:
y=(7*3)
Values can be substituted. Then:
y=(7*7)/3
y=49/3
If y varies directly from x, then the value of y = 49/3 when x = 7.
If y varies directly from x, we can write its relationship in the form of the equation below :
y = m*x
Where m is the slope of the line on the graph.
From the given data:
y=7
x=3,
We can substitute these values in the above equation and find m :
7 = m*3
m = 7/3
So, the equation can also be written as follow:
y = 7/3 x
Finding y when x=7, then substituting the x value in the above equation we get:
y = (7/3)*(7)
y = 49/3
Therefore the value of the y = 49/3.

The slope-intercept form of the inequality is given as follows:
y-4≥-2x-6y ≥ -2x -6 + 4y ≥ -2x-2.What is the slope-intercept format of a function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.Hence the inequality for this problem is simplified as follows:
y-4≥-2x-6y ≥ -2x -6 + 4y ≥ -2x-2.More can be learned about slope-intercept at https://brainly.com/question/24808124

R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)}
Find the values of a and b that complete the mapping diagram.
An effective visual representation of a function or a mapping between two sets is a mapping diagram. It consists of two vertical columns, one of which represents the domain set items and the other of which represents the range set elements. The items in the range set that match to those in the domain set are listed in the right column, and vice versa.
I assume you are given a mapping rule that relates elements in a set to other elements in another set, and you are asked to complete a mapping diagram based on this rule.
If the mapping rule is not specified, we cannot determine the values of a and b. However, assuming that the mapping rule is such that each element (x, y) in the set R is mapped to [tex](x + a, y + b)[/tex], we can complete the mapping diagram as follows:
The given set R is:
R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)}
If we apply the mapping rule to each element in R, we get:
(-3, -2) → (-3 + a, -2 + b)
(-3, 0) → (-3 + a, 0 + b)
(-1, 2) → (-1 + a, 2 + b)
(1, 2) → (1 + a, 2 + b)
To complete the mapping diagram, we need to find the values of a and b such that each mapped element is in the set R. That is, we need to find a and b such that:
(-3 + a, -2 + b) ∈ R
(-3 + a, 0 + b) ∈ R
(-1 + a, 2 + b) ∈ R
(1 + a, 2 + b) ∈ R
Substituting the values of R into each of these equations, we get:
(-3 + a, -2 + b) = (-3, -2), which gives a = 0 and b = 0
(-3 + a, 0 + b) = (-3, 0), which gives a = 0 and b = 0
(-1 + a, 2 + b) = (-1, 2), which gives a = 0 and b = 0
(1 + a, 2 + b) = (1, 2), which gives a = 0 and b = 0
Therefore, the values of a and b that complete the mapping diagram are a = 0 and b = 0.
