Answer:
192m³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a square based pyramid
The highlighted figure is a square based pyramid
The volume of a pyramid is
V=a²h/3
Where a= base length
h= height
Given a= 8m
h= 9m
Volume = 8²*9/3
Volume = 64*3
Volume = 192m³
<span>3a(8a – 6b)
= 24a^2 - 18ab
answer is </span><span>24a2 – 18ab (the last one)</span>
Answer:
11 hours
Step-by-step explanation:
The number of machines working in the factory = 6 machines
Decreasing it by a factor of 2 =
6 ÷ 2 = 3 machines.
Hence:
If 6 machines complete a big order = 22 hours
3 machines = x hours
Cross Multiply
6 machines × x hours = 22 hours × 3 machines
x hours = 22 hours × 3/6
= 66/6
x = 11 hours
Therefoee, it would take 11 hours to fill the order if the number of working machines decreased by factor of 2.
Answer:
10%
Explanation:
Use future value formula
Future Value = Present Value ((1+r)^n)
26,600 = 20,000 ((1+r)^3
26,600/20,000 = (1+r)^3
1.33 = (1+r)^3
1.33^1/3 = 1+r
1.0997 = 1+r
1.0997 - 1 = r
r = 0.997 = 9.97% = 10% (rounded of to the nearest whole percentage)

The answer is c (x+21) and (x-2) you have to find two numbers that multiply yo give you -42 and add to give you 19
