Answer:

970 m²

Step-by-step explanation:

square area= 20×20=400m²

Triangle area=38×30/2=1140/2=570m²

total area=400m²+570m²=970m²

Answer:

Step-by-step explanation:

OK 20 by 20 is 40 so then 38 by 30 is 1140 then divide by 2 which is 570 then add 400 so the answer is 970 (im pretty sure this is wrong)

This month the Middle School Media newspaper has 25 pages. Twenty-five schools order the paper for each of their students. Each

musickatia [10]

Answer:

25^4

Step-by-step explanation:

Here, we want to find the expression that shows the total number of pages in all of the news papers

Number of pages per book = 25

Number of schools is 25

Number of classrooms is 25

Number of students per classroom is 25

Now; the number of students in each school

is 25 * 25

Number of students in all of the school will be;

25 * 25 * 25

So the number of pages in all of the schools will be;

25 * 25 * 25 * 25 = 25^4

Quadrilateral LMNO is similar to quadrilateral PQRS. Find the measure of side QR.

dalvyx [7]

Answer:

The measure of the side $QR$ is 8.8.

Step-by-step explanation:

Since $LMNO \sim PQRS$ , then $SP \propto OL$ , $RS \propto ON$ , $RQ \propto MN$ and $QP \propto LM$ . From figure we have the following relationship:

$k = \frac{OL}{SP} = \frac{ON}{RS} = \frac{MN}{QR} = \frac{ML}{QP}$ (1)

Where $k$ is the proportionality ratio.

If we know that $SP = 13, OL = 55, MN = 37$ , then the measure of side $QR$ is:

$k = \frac{OL}{SP}$ (1b)

$k = \frac{55}{13}$

$k = \frac{MN}{QR}$

$QR = \frac{MN}{k}$ (1c)

$QR = \frac{37}{\frac{55}{13} }$

$QR = 8.745$

The measure of the side $QR$ is 8.8.

Mark wants to improve his free throw percentage in basketball He has shot 1,250 free throws over the last 20 days. He shot eithe

Sedaia [141]

Let's use a for number of days when he shot 50 shots and b for number of days when he shot 100 shots.
We have:
a + b = 20

We also know that he shot total of 1250 shots:
50a + 100 b = 1250

We have two equations. We can solve them for a and b. Let's rearange first equation for a:
a= 20 - b
We insert this into second equation:
50 * (20 - b ) + 100b = 1250
1000 - 50b + 100b = 1250
50b = 250
b = 5
a = 20 - 5
a = 15

Mark shot 100 shots on 5 days.
