Find the area AND perimeter of this shape.

Mathematics
1 answer:
RoseWind [281]2 years ago
3 0

Answer:

Area: 2206.86 square m

Perimeter: 194.25 m

Step-by-step explanation:

Area:

30 x 50 = 1500 square m

30/2 = 15 = the radius of the semi circles

pi x 15^2 = 706.86 square m

1500 + 706.86 = 2206.86 square m

Perimeter:

pi x 15 x 2 = 94.25 m

94.25 (perimeter of both semi circles) + (50 x 2) = 194.25 m

Answer:

read explanation

Step-by-step explanation:

rearrange equations to form y=mx+b

-2x+4=2y

-x+2=y

-y=-2x-5

y=2x+5

use these equations to find slope and y intercepts, and match those with the right graph

slope of first: -1

slope of second: 2

y-int of first: 2

y-int of second:5

The length of a rectangle is five less than its width. The area of the rectangle is 84 square feet. Write a quadratic equation i
salantis [7]

<u>Given</u>:

The length of a rectangle is 5 less than its width.

The area of the rectangle is 84 square feet.

We need to determine the quadratic equation in standard form that represents the area of the rectangle.

<u>Dimensions of the rectangle:</u>

Let l denote the length of the rectangle.

Let w denote the width of the rectangle.

Since, it is given that the length is 5 less than its width, it can be written as,

l=5-w and w=w

<u>Area of the rectangle:</u>

The area of the rectangle can be determined using the formula,

A=length \times width

Substituting A = 84, l=5-w and w=w, we get

84=(5-w)\times w

84=5w-w^2

Adding both sides of the equation by w², we have;

w^2+84=5w

Subtracting by 5w on both sides, we get;

w^2-5w+84=0

Thus, the quadratic equation in standard form for the area of the rectangle is w^2-5w+84=0

Thomas has $6.35 in dimes and quarters. The number of dimes is three more than three times the number of quarters. How many quar
Misha Larkins [42]

q = quarters

dimes is 3 plus 3times quarters

 so 3q is 3 times quarters

 so 3q+3 would be 3 times plus 3


 equation is 3q+3


the value would be 10(3q+3)
