Answer:

282.5 inches squared

Step-by-step explanation:

A triangle is half the area of a square.

So we will solve the area as if we were finding the area for a square, and then we halve the result.

Length multiply by height to get the area:

28.25 × 20 = 565 inches squared

Now, half the answer to get the area of the triangle:

565/2=282.5 inches squared

In 2002, there were 972 students enrolled at Oakview High School. Since then, the number of students has increased by 1.5% each
Katarina [22]

Answer:

The number of student increased each year by 986.58.

Step-by-step explanation:

Given : In 2002, there were 972 students enrolled at Oakview High School.

To find : The number of students has increased by 1.5% each year ?

Solution :

Using the exponential growth function,

P(t)=P_o(1+r)^t

Here, P_o=972 is the initial population

r=1.5%=0.015 is the rate

t=1 time

P(t)=972(1+0.015)^1

P(t)=972(1.015)

P(t)=986.58

i.e. the number of student increased each year by 986.58.

Francis mixes 3/8 gal of white paint, 2 7/8 gal of blue paint, and 1 1/4 gal of red paint.
Rina8888 [55]

List all the info:

3/8 gallon of white paint

2 7/8 gallon of blue paint

11/4 gallon of red paint

First, let’s answer the first question.

Francis has made _____ gal of paint when he first mixes the three colors.

Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.

Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.

Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)
