Answer:
c
Step-by-step explanation:
volume of cylinder = πr^2h
r = 6.5
h = 13+13+13 = 39
cylinder volume = 1647.75π cm^3
volume of one sphere = 4/3 π r^3
= 366.16π cm^3
space not occupied by tennis balls = 1647.75π-3(366.16π)=549.25π cm^3
Complement angles means that the sum of the two angles equal to 90°.
Thus,
x + 8x = 90
9x = 90
x = 10°
8x = 80°
The complement is 80°
Answer: x=-11
Step-by-step explanation:
4(6x+12)=-216 Distribute the 4 in the parenthesis
24x+48=-216
24x=-216
-216 divided by 24
answer= -11
The answer is 73567374 so even
Answer:
D. Kailey is not correct:
is not written in scientific notation.
Step-by-step explanation:
We have been given that Kailey wrote 8,912,000 in scientific notation as
. We are asked to choose the statement that best describes Kailey's work.
We know that to convert a number into scientific notation, we write the given number as product of two numbers. One factor is a number between 1 and 10, while the 2nd factor is power of 10.
Upon looking at
, we can see that 1st factor is 89.10, which is greater than 10. This means that Kailey did not write 8,912,000 in scientific notation.
Therefore, option D is correct choice.
