Answer:
C and D give rational numbers, as the square root of 49 is ±7 and the square root of 100 is ±10.
To find the approximately volume you will use the formula for finding the volume of a cylinder:
V = pi x r^2 x h
3.14 x 0.5^2 x 21
V = 16.485
The volume is approximately 16.49 cubic inches.
Answer:
~ Well congruent means that all sides and angles are equal, so if sides aren’t congruent it means they are not the same size, angle or sides.
Answer:
Add the exponents and keep the bases the same. Then find the reciprocal and change the sign of the exponent
Step-by-step explanation:
When multiplying exponents with the same base number, you can add the powers. (If it was dividing, you would subtract the powers). You would then get
.
- 2³ = 8,
- 2² = 4,
- 2^1 = 2,
- 2^0 = 1
The pattern is to divide by 2. This means that
would be 1 ÷ 2 which is 1/2.
Tip: Any number to the power of -1 means to give its reciprocal.
Hope this helps!
