Answer:
Option B is correct.
volume in cubic millimeters is, 8000 cubic mm
Step-by-step explanation:
Volume of a cube is found by multiplying the length of any edge by itself twice.
It is given by:
cubic units,......[1] where V represents the volume of a cube and a represents the side of a length.
From the given figure;
Length of a side(a) = 2 cm
Use conversion, to convert cm into mm;
1 cm = 10 mm
then;
2cm =20 mm
⇒length of a side(a) = 20 mm
Substitute the value of a = 20 mm in [1];
cubic mm
Simplify:
Therefore, the volume in cubic millimeters is, 8000 cubic mm
Answer:
s/2πh =r
Step-by-step explanation:
s=2πrh
Divide both sides by 2πh to isolate r
s/2πh =2πrh /2πh
s/2πh =r
Answer:
32
Step-by-step explanation:
77 quarters and dimes
q + d = 77
subtract q from both sides
d = 77 - q
---------------------------
A collection of quarters and dimes is worth $12.50 (1250 cents)
25q + 10d = 1250
substitute for d
25q + 10(77 - q) = 1250
distribute
25q + 770 - 10q = 1250
Combine like terms
15q + 770 = 1250
subtract 770 from both sides
15q = 480
divide both sides by 15
q = 32
Answer:
The square root of 162 in its simplest form means to get the number 162 inside the radical √ as low as possible.
Here is how to do that! First we write the square root of 162 like this:
√162
The largest perfect square of the factors of 162 is 81. We can therefore convert √162 like this:
√81 × 2
Next, we separate the numbers inside the √ as such:
√81 × √2
√81 is a perfect square that equals 9. We can therefore put 9 outside the radical and get the final answer to square root of 162 in simplest radical form as follows:
9√2
Step-by-step explanation:
Eight less than the product of 2 and a number x is: 2x-8
