AREA OF A RECTANGLE IS 42 UNITS
Rectangle: Triangle:
A = L * W A = hb / 2
A = (x-8) * 6 A = (7(x-3)) / 2
A = 6x - 48 A = (7x - 21) / 2
Since the problem states that both rectangle and triangle have the same area.Then:
6x - 48 = (7x - 21) / 2
1) Eliminate the denominator 2 by multiplying both sides by 2.
2 * (6x - 48) = 2 * ((7x - 21) / 2)
12 x - 96 = 7x - 21
Find x. Transfer like numbers and change their signs.
12x - 7x = 96 - 21
5x = 75
5x / 5 = 75 / 5
x = 15
Substitute x by its value:
Rectangle: Triangle
A = (x-8) * 6 - A = (7(x-3)) / 2 Areas of both Rectangle
A = (15 -8 ) * 6 A = (7(15-3)) / 2 and Triangle is the same.
A = 7 * 6 A = (7 * 12) / 2
A = 42 units A = 84 / 2
A = 42 units
Answer:
B
Step-by-step explanation:
Since both angles together need to equal 180, set up your formula as
(x+30)+(x+10)=180
2x+40=180
Answer:
1. V = 94 meters cubed
2. V = 8 feet cubed
3. V = 57 inches cubed
Step-by-step explanation:
The volume of a cone is 1/3 the volume of a cylinder. So all you need to do is plug the numbers into the formula for the volume of a cylinder and then you have the answer.
The formula for a cylinder is V= (3.14 or pi) * radius squared * height
The formula for a cone is V= (3.14 or pi) * radius squared * height * 1/3
So here you go.....
1. V= 3.14 x 9 x 10 x 1/3 V = 94 meters cubed
2. V= 3.14 x 4 x 2 x 1/3 V = 8 feet cubed
3. V = 3.14 x 9 x 6 x 1/3 V = 57 inches cubed
