Answer:
26
Step-by-step explanation:
The formula should be
s=
2
r
If 90 inches is the full diameter, cutting it by half will give you the radius, then you just plug in everything else.
*2**45= 26 inches
This answer is better to leave it as pie, so multiply everything else besides the pie.
For this one, plug in your <em>x </em> and <em>y</em> intercepts for the corresponding letters and see which one is true. I always start with the first equation and then see which ones solve it first, that will cut your time down on a test.
Lets start with A. (4,5)
and the first equation y=x+1
5=4+1, which is true so A is a potential answer
B. (2,3)
3=2+1, B is a potential as well
C. (-2,1)
1=-2+1, which is false so C is out
D. (-4,-3)
-3=-4+1, which is true.
To cut down on time, do the same thing with the second equation and your final answer will be A. (4,5)
Answer:
a series of numbers or quantities in geometric progression.
Step-by-step explanation:
Answer: The length is 24 inches
Step-by-step explanation:
It would be between 11 and 12 because 11 times 11 = 121 and that is smaller than 123. Also 12 times 12 is 144 and 12 a whole number.
