to find the hypotenuse (or the ramp in question 4) you can use the equation
with a and b being the 3 feet and 9 feet and c being the unknown (ramp).
So if you plug 3 and 9 into the equation, it looks like this.
then square them.
simplify.
take the square root of both sides.
is approx. 9.5 so the answer would be H.
Answer:
Length = 9 inches
Step-by-step explanation:
The perimeter of a rectangle is:
perimeter = 2(length + width)
24 = 2(a+b)
a = b + 6
a = length
b = width
then:
24 = 2((b+6)+b)
24/2 = b+6+b
12 = 2b + 6
12-6 = 2b
6 = 2b
b = 6/2
b = 3 inches
a = b+6
a = 3+6
a = 9 inches
Check:
24 = 2(9+3)
24 = 2*12
Answer:
96 cm^2
Step-by-step explanation:
All faces of a cube are equal in area.
Therefore the Formula for SA of a cube is 6*s^2
SA = 6*4*4 = 96
Answer:
an = 7.5 - 5.5(n - 1).
Step-by-step explanation:
The common difference d = -5.5.
The first term is given as 7.5.
Explicit formula is
an = a1 + (n - 1)d
= 7.5 + (n - 1)-5.5
= 7.5 - 5.5(n - 1)
