Answer:
-8
Step-by-step explanation:
First combine like terms:
4x-8=32+9x
-40=5x
-8=x
Answer:
See below
Step-by-step explanation:
Use the formulae directly
For a cone, with base radius = r and height = h, here are the related formula
(1)


(2)
(3)
Therefore directly plugging in the numbers in the above equations:
Note:
l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm
Figure(a)
r = 4, h = 8

Figure(b)
r = 7, h =15


Figure (c)
r = 5, l = 8

Answer:
3x - 14
Step-by-step explanation:
Perimeter = 2(length+width)
= 2[(½X-7) + (x)]
= 2[½x + x - 7]
= 2[1.5x - 7]
= 3x - 14
Find his rate:
120 / 15 = $8 per hour
Multiply the rate by hours:
$8 x 20 hours = $160
He will earn $160
