Answer:
Terrance is incorrect
Step-by-step explanation:
Supplementary angles add to 180 degrees
4x+30 + 2x+6 = 180
Combine like terms
6x+36 = 180
Subtract 36 from each side
6x+36-36 = 180 -36
6x =144
Divide by 6
6x/6 = 144/6
x =24
16.625
Step-by-step explanation:
a=pi*radius squared
3.14*2.5*2.5
16.625

Step-by-step explanation:</h2>
Multiplication is when you have a number that you need to multiply by that number. Okay, let me give you an example:
2x4 means = 2+2+2+2 or 4+4
3x6 means = 3+3+3+3+3+3 or 6+6+6
the answer will always be the same.
GOOD LUCK !! :)

Answer: b=2(square root of 2) and a=4
Step-by-step explanation:
Since this is a 45-45-90 triangle we know that side b is equal to
.
In a 45-45-90 triangle, the hypotenuse is equal to
this means in order to find missing side length a, we have to multiply
this will give us 4
so the missing side lengths are,
and 
Answer:
About 36%.
Step-by-step explanation:
The formula for the rate of return on investment is the total value minus the initial cost divided by the initial cost.
The total value is $1,500. The initial cost is $1,100.
(1,500 - 1,100) / 1,100 = 400 / 1,100 = 4 / 11 = 0.363636363636
So, Dean's rate of return on investment is about 36%.
Hope this helps!
