Answer:
73.4846922835 = 73.5 and no it is not a perfect square 5400/100 = 54
Answer:
V = 8 cm³
Step-by-step explanation:
This is basically the formula for volume of pyramid:
Volume of Pyramid = 1/3 × Base Area x Height
OR
Volume of Pyramid = (Base Area x Height)/3
V = Bh/3
Given:
B = 4 cm²
h = 6 cm
V = Bh/3
= (4 x 6) / 3
= 24 / 3
V = 8
Hence
V = 8 cm³
If you want to represent this into inches simply divide 8 with 2.54 as
1 cm = 2.54 inches So,
8 cm / 2.54 cm = 3.15 in
shorter side : longer side = 3 : 7
Equate 3 parts tp 9 inches:
3 parts = 9 inches
Find 1 part:
1 part = 9 ÷ 3 = 3 inches
Find 7 parts:
7 parts = 3 x 7 = 21 inches
Area = Length x Width = 21 x 9 = 189 in²
Answer: The longer side is 21in and the area is 189 in²
Answer:
1,735-3
Step-by-step explanation:
It said decreases so it would be subtracted
The solution to the equation would be 21.5
Why?
If you do the equation backwards
30 - 8.5 = x
You would get 21.5
You can plug it into the first equation to check!
