Answer:

72 cans

Step-by-step explanation:

step 1

Find the number of people

we know that

She ordered 1 pizza for every 4 people

using proportion

Find out the number of people for 6 pizzas

$\frac{1}{4}=\frac{6}{x}\\\\x=24\ people$

step 2

Find the number of cans ordered

we know that

Charissa ordered 3 cans of lemonade for each person

using proportion

Find out the number of cans of lemonade she ordered for 24 people

$\frac{3}{1}=\frac{x}{24}\\\\x=24(3)\\\\x=72\ cans$

The perimeter of a playing card is 30 centimeters. It is 9 centimeters tall. How wide is it?PLS HELP!

zlopas [31]

Answer:

6 cm.

Step-by-step explanation:

The perimeter = 2(H + W) where H = height and W = width. So we have:

30 = 2(9 + W)

30 = 18 + 2W

2W = 30 - 18 = 12

W = 6 cm.

Answer:

Question 1. Correct choice A

Question 2 Correct choice A

Step-by-step explanation:

To answer the first question, let's do the following operation, subtract the salary for n years of education with the salary for n-1 years of education:

$(125.66x_{2}-846.3) - (125.66x_{1}-846.3)\\$

Where:

$x_{2}$ represents n years of education

$x_{1}$ represents n-1 years of education.

Then, solving:

$(125.66x_{2}-846.3) - (125.66x_{1}-846.3) = 125.66x_{2}-846.3-125.66x_{1} + 846$ .

$= 125.66x_{2}-125.66x_{1}\\$

$= 125.66 (x_{2}-x_{1})$ Since $x_{2}$ is always a unit greater than $x_{1}$ , its subtraction is always equal to 1.

$= 125.66(1)\\ = 125.66$

This result shows that the increase for an additional year of education is always equal to the value of the slope of the line, that is, $ 125.66. Therefore the correct option for this question is "A".

In cuano to the second question:

The intersection of the line with the y-axis occurs when the value of x is equal to zero, or in this case, when the years in the collage are 0.

This means that when there are no years of education in the collage, the salary is expected to be equal to the value of the intersection of the line with the axis y, that is, equal to 24,600 thousand dollars.

Then the correct option is A.
