If there are 30 Apple computers and 7 of the computers have a specialized movie editing software, then that would be 23.3333333% of the Apple computers can be used for editing movies.
7/30x100= 700/30
700/30= 23.33%
Answer:
x = 3
Step-by-step explanation:
Equation: 4x = 3(1 + x)
Distribute the 3: 4x = 3 + 3x
Subtract 3x from both sides: x = 3
Answer:
The statement that's known to be always true is known as tautologies whereas the statement that's known to be always false is known as contradiction.
Answer:
width = 20
length = 28
Step-by-step explanation:
perimeter=96
width=x
length=x+8
(length*2) + (width*2) = perimeter
2(x+8) + 2(x) = 96
2x+16+2x=96
4x+16=96
4x=80
x=20
width = 20
length = 28
For partial circles, first imagine that there is an entire circle. To find the area of a cicle, you use the formula A=pi*r^2 or A=3.14*r^2. Then determine how much of a circl you have so you can alter the formula. Since you have a semicircle, or half a circle, simply divide the formula in half:
A=(3.14*r^2)/2
Then plug in your radius to find the area. So for this problem you do:
A=(3.14*3^2)/2
A=28.26/2
A=14.13 is the area of the semicircle
Then since the rectangle would be 108 (18*6)
The total area is 122.13 (14.13+108)
Hope this helps!
