Last year He was 7 years old.
His father is 4 times the age 7 x 4 = 28
Last year his dad was 28, so this year he is 29.
Combined age this year = 29 + 8 = 37
51 - 37 = 14 years
14/ 2 people = 7 years
8 + 7 = 15
29 + 7 = 36
15 + 36 = 51
It will take 7 years.
It's an isosceles triangle because they have two angles and two sides that are identical
Answer:
B
Step-by-step explanation:
Answer:
9.42
Step-by-step explanation:
Hey There!
The first step of this problem is to find the formula for arc length
r=raduis
0 = angle
now we just plug in the values
so the arc length equals 9.424777961
the last step is to round to the nearest hundreth
so your final answer is 9.42
Answer: The correct equation is the option A.)A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
Step-by-step explanation:
To find the painted area of the theater room in square feet, the following steps must be followed:
1. Determine the area of the theater room
Length: x
Width: x-4
A (theater room) = x (x-4)
2. Determine the area of the right triangle
Height: x-4
Base: 8
A (right triangle) = 0.5 (8) (x-4)
3. Determine the area of the rectangle inside labeled closet
Length: 8
Width: 4
A (closet) = 8 (4)
4. The area to be painted will be the substraction between the total area of the theater room, less the area of the right triangle and less the area of the rectangle of the closet like this:
A= A(theater room) - A(right triangle) - A (closet)
A = x (x-4) -0.5 (8) (x - 4) - 4 (8)
Therefore, the correct equation to solve by area is option A
