Answer:

1/20 liters per statue

so you divide 7/8 by 1/20

7/8*20/1

17.5 statues

but there cant be decimal statues,

so 17 statues is the answer

Answer:

17 statues.

Step-by-step explanation:

7/8 / 1/20

= 7/8 * 20

= 140/8

= 17.5.

Answer:

26 students/bus

Answer

925 students brought their lunch.

Explanation

First let's rewrite the equation.

You know that "of" means multiply and "is" means equal.

Okay, so let's break it down.

The question says, "At your school, 74% of students brought their lunch at the cafeteria. There are 1250 students in the school."

This means that 74% of 1250 students brought their lunch at the cafeteria.

You are trying to find how many students brought their lunch. This will be x.

So the equation would be this.

74% × 1250 = x

74% is 0.74.

0.74 × 1250 = x

0.74 × 1250 = 925

So 925 students brought their lunch.

Answer:

The perimeter is 19.7

Step-by-step explanation:

The question is not complete and there is no attachment. Nevertheless, we can make do with the given information.

we can picture that the shape is a circle and we are required to find the perimeter/circumference of the circular shape

Given

The radius r= 3.142

Step two:

the perimeter/circumference is expressed as

C=2πr

C= 2*3.142*3.142

C= 19.7

Dimes are 0.10 each

Pennies are 0.01 each

You need 4 pennies to get the 0.04

Then you would have 3 dimes .

3 x 0.10 = 0.30

4 x 0.01 = 0.04

0.30 + 0.04 = 0.34

Answer:

20 feet

Step-by-step explanation:

Parimeter is how far you would walk if you made a lap around the shape, walking on the edge lines like a balance beam.

To find perimeter, we need to add up all the sides.

Because it's a square each side has the same length.

There are 4 sides.

5 x 4 = 20

or 5 + 5 + 5 + 5 = 20

The perimeter is 20 feet

Answer:

SSS

Step-by-step explanation:

The SSS theorem is the side-side-side theorem. Basically, since all three sides from one triangle is congruent to the corresponding sides of the other triangle, then the triangles have to be congruent. There are other theorems such as the SAS theorem (side-angle-side), but since the question only give us the fact that the sides are congruent, its SSS. Sorry, I hope this is good enough. XD

Answer:

50  miles

Step-by-step explanation:

50 because 1 inch is 20 miles. There is two and a half inches.

Answer:

x = 7

Step-by-step explanation:

Given

2(2x + 1) = 30

4x + 2 = 30

4x = 30 - 2

4x = 28

x = 28/ 4

x = 7

Hope it helps :)❤

Answer:

x= 7

Step-by-step explanation:

2(2x+1) =30

2×2x+2×1=30

4x+2=30

4x=30-2

4x=28

x=28÷4

x=7

Answer:

23 ft

Step-by-step explanation:

The computation of the maximum length of the base of the triangle is as follows:

Area of triangle is = 4 × 6 ÷ 2

= 12 ft²

Now the maximum area of the rectangle is

= 150 - 12

= 138 ft²

L = ?

W = 6 ft

Area of rectangle is  = L × W

L × 6 = 138

L = 138 ÷ 6

= 23 ft

Answer:

 y = -1/3x + 3 2/3

Step-by-step explanation:

step 1. find the slope of the given line

y2-y1/x2-x1          2 - 4/ 3 + 3 = - 1 / 3

take the opposite of that and there is your slope

step 2. plug in the values to the following equation using the given point:

y - y1 = m ( x - x1 )          y - 4 = - 1/3 ( x + 1 )

step 3. solve for y

y-4 = -1/3(x+1)

-1/3(x) and -1/3(1)  ----> y-4 = -1/3x-1/3

y-4+4 = -1/3x-1/3+4  ---->  y = -1/3x + 3 2/3
