Answer:

Part A:  A ratio of 2:1  means that he uses 2 cups of yellow paint for each cup of blue paint.

-------------------------------------------------------------------------------------------------

Part B: The ratio of yellow to blue is 2:1 = 2/1. So, if for 2 yellow is 1 blue, then for 1 yellow is x:

2/1 = 1/x

x = (1*1) / 2

x = 1/2

For each cup of yellow paint, Greg should add 1/2 cup of blue paint.

-------------------------------------------------------------------------------------------------

 Part C: 6 cups cost $54, then 1 cup cost:

54 / 6 = 9

The price per cup of yellow paint is $9.

A.  The number of cups of yellow paint that Greg mixed with each cup of blue paint is (1/2) cup.

B.  Greg should add 2 cups of blue paint to each cup of yellow paint.

C. The unit price of per cup of yellow paint is 9 dollars.

The ratio compares similar quantities in simplest form.

Given that the ratio of the number of cups of yellow paint to the no. of cups of blue paint to make a green shade paint is 2:1.

This can also be written as

(yellow paint/blue paint) = (2/1).

∴ 1 cup of yellow paint and 2 cups of blue paint is required to make a green shade of paint.

A. The number of cups of yellow paint that Greg mixed with each cup of blue paint is (1/2) cup.

B. Greg should add 2 cups of blue paint to each cup of yellow paint.

C. The unit price of per cup of yellow paint is (54/6) = 9 dollars.

The function relating in indira‘s height to the number of hours she mountain climbing is: y = -36.5x + 182.5

A linear equation is given by:

y = mx + b;

where m is the slope(rate of change), b is the initial value of y, y is the dependent variable and x is the independent variable.

Let x represent the number of hours spent climbing the mountain and y represent the distance above see level.

She starts at 182.5 meters above sea level, hence; b = 182.5 meters

She descends 36.5 meters each hour, hence m = -36.5 meter per hour

Therefore the equation becomes:

y = -36.5x + 182.5

Based on past data, we can expect that 2 preschoolers will be reading books today out of the total of 24 preschoolers present. we can apply this ratio to the total number of preschoolers present today.

To determine the expected number of preschoolers who should be reading books today, we can use the ratio of the number of preschoolers who chose to read books yesterday to the total number of preschoolers present yesterday.

Yesterday, there were 24 preschoolers present, and 2 of them chose to read books. Therefore, the ratio of preschoolers reading books to the total number of preschoolers yesterday is:

2 / 24

To find the expected number of preschoolers reading books today, we can multiply this ratio by the total number of preschoolers present today (which is 24):

(2 / 24) * 24

Simplifying this expression, we find:

2

Answer:

x = - 7

Step-by-step explanation:

Sum of interior angles is a triangle is 180,

70 + 55 + 62 + x = 180

187 + x = 180

x = 180 - 187

x = - 7

Answer:

C) -7

Step-by-step explanation:

1. All the angles in a triangle add up to 180°. This means that x + 62 + 70 + 55 = 180.

2. (Solving equation above)

Step 1: Combine like terms.

Step 2: Subtract 187 from both sides.

Step 3: Check if solution is correct.

Therefore, the answer is C) -7.

Answer:

∛27 = 3

Step-by-step explanation:

A radical is simply a fractional exponent: [tex]a^{(\frac{m}{n})} = \sqrt[n]{a^{m} }[/tex]

Hence, ∛27 = [tex]27^{(\frac{1}{3})}[/tex]

Since 27 = 3³, then:

You could rewrite ∛27 as ∛(3)³.

[tex]\sqrt[3]{3^{(3)} } = 3^{[(3)*(\frac{1}{3})]}[/tex]

Multiplying the fractional exponents (3 × 1/3) will result in 1 (because 3 is the multiplicative inverse of 1/3). The multiplicative inverse of a number is defined as a number which when multiplied by the original number gives the product as 1.

Therefore, ∛27 = 3.

Hi there!

We know that:

m∠WXZ = 112°

Since m∠1 is 48° greater than m∠2, we can write an expression:

m∠2 = x°

m∠1 = (x + 48)°

Since both angles sum up to m∠WXZ, we can write this as:

112° = x° + (x + 48)°

Solve for x:

112 = 2x + 48

64 = 2x

x = 32°
