Muffy ordered 3 muffins and 2 lattes for $7. Sammy ordered 4 muffins and a latte for $6. Create a system of equations. ​

Answer:

X = 90 , Y = 37 and Z = 53 Degrees.

Step-by-step explanation:

Z = 53 as opposite angles of a parallelogram are equal

Therefore, Z + Y + 90 = 180 ( Angle sum Property of a triangle)

= 53 + Y + 90 = 180
Y = 180 - 143
Y = 37

Now to find x , we know Y is the Alternate Interior angle of the angle adjacent to the 90*

Keeping that angle as "o"

Angle O = Angle Y by Alternate Interior Angle Therom

Therefore , Angle X + Angle O + 53 = 180 (ASP of triangle)

Angle X + 37 + 53 = 180

Angle X = 180 - 90
Angle X = 90*


In summary , X = 90 , Y = 37 and Z = 53.

Hope it helps.

After answering the presented question, we can conclude that As a equation result, approximately 44.4% of the original trees are still living after three years.

An equation is a mathematical statement that proves the equality of two expressions connected by the equal symbol '='. 2x - 5 Equals 13, for example. Expressions include 2x-5 and 13. The character '=' joins the two expressions. A mathematical formula with two algebraic expressions on either side of an equal sign (=) is known as an equation. It demonstrates the relationship of equivalence between the left and right formulas. In every formula, LHS = RHS (left side = right side).

Assuming that all of the trees on the farm are cut down each year, the percentage of trees that survive after three years is as follows:

60% of the trees die after the first year, leaving only 40% of the original trees.

Following the first year, 40% of the original trees are still standing.

Following the second year, 40% of the original trees remain + (40% of the original trees * 100% - 60% = 40% stump growth) = 64% of the original trees remain.

Following the third year, 40% of the original trees remain + (64% of the original trees * 100% - 60% = 4.4% stump growth) = 44.4% of the original trees remain.

As a result, approximately 44.4% of the original trees are still living after three years.

The factored form of 3x^2 + 13x - 10 is (3x - 2)(x + 5).

To factor 3x^2 + 13x – 10 by grouping, we need to find two numbers whose product is 3(-10) = -30 and whose sum is 13.

Let's list all the factor pairs of -30:

-1, 30

-2, 15

-3, 10

-5, 6

Out of these pairs, the pair that adds up to 13 is -2 and 15.

We can use these numbers to rewrite the middle term:

3x^2 - 2x + 15x - 10

Now, we can group the first two terms and the last two terms:

(3x^2 - 2x) + (15x - 10)

We can factor out the greatest common factor from each group:

x(3x - 2) + 5(3x - 2)

Now, we can see that we have a common factor of (3x - 2):

Nora can construct a kite with diagonals that bisect each other if the kite is in the shape of a rhombus.

The way that a Rhombus is drawn is such that ∠ GKJ and ∠ HGK would add up to 180 degrees. If these angles are bisected as shown, then the corresponding angles would add up to 90 degrees as a result.

Step-by-step explanation:

The probability that a random sample of 106 pregnancies has a mean gestation period of 262 days or less is 0.00003.

What is probability?

Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probabilities are usually expressed as fractions, decimals, or percentages.

(a) To find the probability that a randomly selected pregnancy lasts less than 262 days, we need to standardize the value using the formula z = (x - μ) / σ, where x is the value we're interested in, μ is the mean, and σ is the standard deviation.

z = (262 - 266) / 16 = -0.25

Using a standard normal distribution table or calculator, we find that the probability of getting a z-score of -0.25 or less is 0.4013. Therefore, the probability that a randomly selected pregnancy lasts less than 262 days is 0.4013.

(b) The sampling distribution of the sample mean length of pregnancies is approximately normal with mean μ = 266 and standard deviation σ = 16 / sqrt(51) = 2.2449. This is known as the central limit theorem.

Using a standard normal distribution table or calculator, we find that the probability of getting a z-score of -2.8304 or less is 0.0023. Therefore, the probability that a random sample of 51 pregnancies has a mean gestation period of 262 days or less is 0.0023.

(d) Using the same formula as in part (c), we have:

z = (262 - 266) / (16 / sqrt(106)) = -4.0077

Using a standard normal distribution table or calculator, we find that the probability of getting a z-score of -4.0077 or less is 0.00003.

Therefore, the probability that a random sample of 106 pregnancies has a mean gestation period of 262 days or less is 0.00003.

The baby will drink 45 liters of milk in 30 days when baby drink 3 liters of milk in 2 days.

To solve this problem, we can set up a proportion using the fact that the amount of milk the baby drinks is directly proportional to the number of days:

milk consumed / number of days = constant

Let's call the constant of proportionality k. Then we can write:

3 liters / 2 days = k

To find the value of k, we can solve for it:

k = 3 liters / 2 days = 1.5 liters/day

Now we can use this value of k to find how much milk the baby will drink in 30 days:

milk consumed / 30 days = 1.5 liters/day

Multiplying both sides by 30, we get:

milk consumed = 1.5 liters/day x 30 days = 45 liters

Therefore, the baby will drink 45 liters of milk in 30 days.

As per the volume, the height of the fish tank is 0.4 inches.

First, we are given that the width of the tank is w inches, the length is w+8 inches, and the height is 18-w inches. We also know that all dimensions are greater than 6 inches. Using the formula for the volume of a rectangular prism, we can write:

V = lwh

Substituting the given values, we get:

1440 = (w+8)(w)(18-w)

Now, we can simplify this equation by expanding the product on the right-hand side:

1440 = 18w² + 8w(18-w)

Simplifying further, we get:

1440 = 18w² + 144w - 8w²

Combining like terms, we get:

10w² + 144w - 1440 = 0

Dividing both sides by 10, we get:

w² + 14.4w - 144 = 0

Now we can solve for w using the quadratic formula:

w = (-b ± √(b² - 4ac)) / 2a

where a = 1, b = 14.4, and c = -144. Plugging in these values, we get:

w = (-14.4 ± √(14.4² - 4(1)(-144))) / 2(1)

Simplifying, we get:

w = (-14.4 ± √(432.16)) / 2

w = (-14.4 ± 20.8) / 2

w = -17.6 or w = 3.6

Since we know that all dimensions are greater than 6 inches, we can eliminate the negative solution and conclude that w = 3.6 inches is not valid. Therefore, the width of the tank is w = 17.6 inches.

Now we can use this value to find the height of the tank. Substituting w = 17.6 into the expression for the height, we get:

h = 18 - w

h = 18 - 17.6

h = 0.4

Therefore, the height of the tank is h = 0.4 inches, or equivalently, 4/10 of an inch.

5/6

Answer:

See below.

Step-by-step explanation:

We are asked to Add Fractions.

Fractions are parts of a single whole number.

To make adding these fractions similar, we should have a common denominator.

[tex]\frac{Numerator}{Denominator}[/tex]

When we add common denominators, they remain the same. This makes adding fractions much easier.

Let's identify the common denominator by finding the Least Common Multiple. (LCM)

The LCM is the smallest common multiple that 2 numbers have. A multiple is the product of that number.

An Example of Multiples:

[tex]4; 4 \times 1, 4 \times 2, 4 \times 3, 4 \times 4, 4 \times 5, 4 \times 6.\\4; 4, 8, 12, 16, 20, 24.[/tex]

An Example of the LCM:

[tex]4; 4, 8, 12, 16, 20, [24], 28\\6; 6, 12, 18, [24], 30, 36, 42. \\The \ LCM \ is \ 24.[/tex]

Let's use the example above as a guide, but for our values in the denominator.

[tex]2; 2, 4, [6], 8, 10, 12, 14.\\3; 3, [6], 9, 12, 15, 18, 21.\\The \ LCM \ is \ 6.[/tex]

Our Denominators will be 6.

Multiply both the Numerator and the Denominator by the number needed to make the denominator 6.

[tex]\frac{1 \times 3}{2 \times 3}=\frac{3}{6} \\\frac{1 \times 2}{3 \times 2} = \frac{2}{6}[/tex]

Add:

[tex]\frac{3}{6} + \frac{2}{6} = \frac{5}{6} \\[/tex]

Our final answer is [tex]\frac{5}{6} .[/tex]
