Answer:
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
Step-by-step explanation
supplementary angle=180
(5x + 27)° + (5x – 7)º=180
5x+27+5x-7=180
10x+20=180
10x=180-20
10x=160
x=160/10
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
107+73=180
Answer:
300ft^2
Step-by-step explanation:
Total surface area = Area of base + (1/2) x perimeter of base x slant height
Area of base = length² = 10 x 10 = 100
Perimeter of base = 2 ( length + breadth)
2 x 20 = 40
slant height = 10
100 + (1/2) x 40 x 10 = 300 ft^2

Answer:
The height of the pile is increasing at the rate of 
Step-by-step explanation:
Given that :
Gravel is being dumped from a conveyor belt at a rate of 20 ft³ /min
i.e 
we know that radius r is always twice the diameter d
i.e d = 2r
Given that :
the shape of a cone whose base diameter and height are always equal.
then d = h = 2r
h = 2r
r = h/2
The volume of a cone can be given by the formula:




Taking the differentiation of volume V with respect to time t; we have:


we know that:

So;we have:



The height of the pile is increasing at the rate of 
1/2 gallon of paint covers 1/12 of a wall
, 12 times as much paint will cover 12 times the area you can solve this by 12*1/2=6.
