The value of x from the given isosceles triangle is 8 units.

The measures of sides of triangle are given AB=4x-10, AC=5x-22 and BC=3x+2.

What is an isosceles triangle?

Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.

Here, AC = BC

⇒ 5x-22 = 3x+2

⇒ 5x-3x = 22+2

⇒ 3x = 24

⇒ x = 8 units

Therefore, the value of x from the given isosceles triangle is 8 units.

The ratio 25 : 15 as a fraction in the simplest form can be written as 5/3.

What is ratio?

The quantitative relation between two amounts showing the number of times one value contains or is contained within the other. Ratio are represented in the following way -  a : b, c : d etc

Given is 25 to 15.

We can express this ratio as a fraction in the simplest form as -

25 : 15 = 25/15

Now, we have to ensure that only whole numbers are their in the numerator and denominator. So in simplest form, we can write -

25 : 15 = 25/15 = (5 x 5)/(5 x 3) = 5/3

Simplest form in fraction will be 5/3

Therefore, the ratio 25 : 15 as a fraction in the simplest form can be written as 5/3.

What are the coordinates of the point on the directed line segment from (3,-3) to (7,5) thar oartitions the segment into a ratio of 5 to 3?

Answers

Answer:

(x, y) = (5.5, 2)

Explanation:

The coordinates of a point that divide the segment from point (x1, y1) to (x2, y2) into a ratio of a:b can be found using the following equations:

[tex]\begin{gathered} x=x_1+\frac{a}{a+b}(x_2-x_1) \\ y=y_1+\frac{a}{a+b}(y_2-y_1) \end{gathered}[/tex]

So, replacing (x1, y1) by (3, -3), (x2, y2) by (7, 5) and the ratio a:b by 5:3, we get that the coordinates of the point are:

[tex]\begin{gathered} x=3+\frac{5}{5+3}(7-3) \\ x=3+\frac{5}{8}(4) \\ x=3+2.5=5.5 \\ y=-3+\frac{5}{5+3}(5-(-3)) \\ y=-3+\frac{5}{8}(5+3) \\ y=-3+\frac{5}{8}(8) \\ y=-3+5=2 \end{gathered}[/tex]

Therefore, the coordinates of the point are (x, y) = (5.5, 2)

What is money?

Money is any commodity or verifiable record that is widely accepted in a given country or socioeconomic environment as payment for products and services and repayment of debts, such as taxes.

Money enables us to meet our most basic requirements, such as purchasing food and shelter and paying for healthcare. Meeting these demands is critical, and if we don't have enough money to do so, our personal well-being and the community's overall well-being suffer considerably.

In this case, saving the money means that the person is careful with spending and doesn't want to waste the money. This implies thrifty.

282The number of germs in a sample can be measured by the equation f(x)=15x + 145. Temperature represents the domain of the sample while the range isthe number of germs. If a doctor wants to keep the amount of germs to be less than 300,what is the approximate domain of temperatures to keep the sample under 300?

Answers

Answer

The approximate domain temperature is 10

Step-by-step explanation:

Given the following model function

f(x) = 15x + 145

Mathematically

15x + 145 < 300

Collect the like terms

15x < 300 - 145

15x < 155

Divide both sides by 15

15x/15 < 155/15

Robin Sparkles invests $3,760 in a savingsaccount at her local bank which gives 1.8%simple annual interest. She also invests$2,400 in an online savings account whichgives 5.3% simple annual interest. After fiveyears, which one will have earned moreinterest, and how much more interest will ithave earned, to the nearest dollar?

Answers

The formula for determining simple interest is expressed as

I = PRT/100

where

I = interest

P = principal or amount invested

T = time in years

R = interest rate

Considering the amount invested in her local bank,

P = 3760

R = 1.8

T = 5

I = (3760 x 1.8 x 5)/100 = 338.4

Considering the amount invested in online savings,

P = 2400

R = 5.3

T = 5

I = (2400 x 5.3 x 5)/100 = 636

After 5 years, the investment in the online savings account earned more interest.

The difference in interest earned is

636 - 338.4 = $298 to the nearest dollar

It has earned $298 more than the local bank's interest

find the sum to infinity 16,4,1,1/4

Answers

Answer:

The sum to infinity of the given series is;

[tex]S_{\infty}=21\frac{1}{3}[/tex]

Explanation:

From the given series, we can see that the series is a Geometric Progression (GP) because it has a common ratio;

[tex]\begin{gathered} r=\frac{4}{16}=\frac{1}{4} \\ r=0.25 \end{gathered}[/tex]

The formula to calculate the sum to infinity of a GP is;

[tex]\begin{gathered} S_{\infty}=\frac{a}{1-r} \\ \text{For;} \\ 0Where;

a = first term = 16

r = common ratio = 0.25.

substituting we have;

[tex]\begin{gathered} S_{\infty}=\frac{16}{1-0.25}=\frac{16}{0.75} \\ S_{\infty}=21\frac{1}{3} \\ S_{\infty}=21.33 \end{gathered}[/tex]

Therefore, the sum to infinity of the given series is;

Suppose that an airline uses a seat width of 16.2 in. Assume men have hip breadths that are normally distributed with a mean of 14 in. and a standard deviation of 1 in. Complete parts (a) through (c) below.

Answers

Given:

population mean (μ) = 14 inches

population standard deviation (σ) = 1 inch

sample size (n) = 126

Find: the probability that a sample mean > 16.2 inches

Solution:

To determine the probability, first, let's convert x = 16.2 to a z-value using the formula below.

[tex]x=\frac{\bar{x}-\mu}{\sigma\div\sqrt{n}}[/tex]

Let's plug into the formula above the given information.

[tex]z=\frac{16.2-14}{1\div\sqrt{126}}[/tex]

Then, solve.

[tex]z=\frac{2.2}{0.089087}[/tex][tex]z=24.6949[/tex]

The equivalent z-value of x = 16.2 is z = 24.6949

Since we are looking for the probability of greater than 16.2 inches, let's find the area under the normal curve to the right of z = 24.6949.

Based on the standard normal distribution table, the area from the center to z = 24.6949 is 0.5

Since we want the area to the right, let's subtract 0.5 from 0.5.

[tex]0.5-0.5=0[/tex]

Therefore, the probability that a sample mean of 126 men is greater than 16.2 inches is 0.

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 65%pure antifreeze. The company wants to obtain 260 gallons of a mixture that contains 45% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be

Answers

Answer:

80 gallons of water

180 gallons of premium antifreeze solution.

Explanation:

Let's call X the number of gallons of water and Y the number of gallons of the premium antifreeze solution.

The company wants to obtain 260 gallons of the mixture, so our first equation is:

X + Y = 260

Additionally, the mixture should contain 45% of pure antifreeze and the premium antifreeze solution contains 65% pure antifreeze. So, our second equation is:

0.45(X + Y) = 0.65Y

Now, we need to solve the equations for X and Y. So, we can solve the second equation for X as:

[tex]\begin{gathered} 0.45(X+Y)=0.65Y \\ 0.45X+0.45Y=0.65Y \\ 0.45X=0.65Y-0.45Y \\ 0.45X=0.2Y \\ X=\frac{0.2Y}{0.45} \\ X=\frac{4}{9}Y \end{gathered}[/tex]

Then, we can replace X by 4/9Y on the first equation and solve for Y as:

[tex]\begin{gathered} \frac{4}{9}Y+Y=260 \\ \frac{13Y}{9}=260 \\ 13Y=260\cdot9 \\ 13Y=2340 \\ Y=\frac{2340}{13} \\ Y=180 \end{gathered}[/tex]

Finally, replacing Y by 180, we get that X is equal to:

[tex]\begin{gathered} X=\frac{4}{9}Y \\ X=\frac{4}{9}\cdot180 \\ X=80 \end{gathered}[/tex]

Therefore, the solution should have 80 gallons of water and 180 gallons of premium antifreeze solution.
