What is the ratio of red sections to total sections, in lowest terms?

Tanzania [10]

Hello there! Your answer would be 1/4.

So to start, count up the total number of sections, and the number of red sections. There are 16 sections total, and 4 of them are red.

This can give us the ratio 4/16.

But next we need to simplify. What is the biggest number that can be divided by both 4 and 16? 4. So, divide both 4 and 16 by 4 to get your simplified answer.

4÷4/16÷4

1/4

So, the ratio of red sections to total sections, in lowest terms is 1/4.

A rectangle and a square have the same area. The length of the rectangle is seventy feet more than two times its width. The leng

Zanzabum

Using the side of the square find the area:

Area = 30^2 = 900 square feet.

The rectangles area is the same, 900 square feet.

Let the width = X

The length would be 2X + 70

Area = length x width

X * 2x+ 70 = 900

This expands to 2x^2 * 70x = 900

Use the quadratic formula to solve for x:

-70 +/- sqrt(70^2-4*2(-900))/2*2

X = 10

Width = x = 10 feet

Length = 2x + 70 = 90 feet

Can you plz solve 6-8 on this pic you have to find the area for it plz

Sergio039 [100]

Answer:

Figure 3: 28.5 units²

Figure 4: 33 units²

Figure 5: 25 units²

Figure 6: 30 units²

Figure 7: 25 units²

Figure 8: 32 units²

Reasons:

Figure 3 consists of 2 shapes, A rectangle and a square

████████ ◣

rectangle: ████████ triangle: █◣

████████ ██◣

rectangle:

to calculate a rectangle's area: multiply the lengths of the width and height:

████████= width 8 █

█ =height 3

█

$area=w(h)$

now substitute the values of W and H:

$8(3)=24$

rectangle area = 24

Triangle:

to find the area of a triangle, multiply the width and height and divide by two:

◣ + ◣ = █ 0.5 + 0.5 = 1

█

███=width 3 █ =height 3

█

$area=\frac{w(h)}{2}$

now substitute W and H

$area=\frac{3(3)}{2}$

$area\frac{9}{2}$

Triangle area: 4.5

Now add the Rectangle Area To the triangle Area:

4.5 + 24 = 28.5

Final answer:

AREA =2 8.5

hope this helps!
