Answer:
Volume of sphere is 
Step-by-step explanation:
It is given that Hal says that volume of sphere is 
Volume of sphere is given by 
Now using 3.14 in place of 
Now volume of sphere is
Therefore volume of sphere when we use 3.14 in place of is
And the Hal likely error is he uses directly for calculation of volume.
Okay. So in order to solve this problem, we really have to try out each answer and divide it by 9. A is not correct, because it does not divide evenly. B works, but let's check the others. C and D do not work, but E also works as well. If you can have two answers, 504 and 882 are both exactly divisible by 9. The answers are B: 504 and E: 882.
To answer this question you must find the percentage of the children that read before bed and compare it to the adults bag read before bed’s percentage.
To do this, start by dividing the number of children that read before bed by the total number of children surveyed.
This leaves you with:
6/13= 0.4615
To find the actual percentage, multiply this result by 100.
0.4615 x 100 = 46.15
This percentage rounded is 46%
So, now you can compare the percentages. The percentage of children that read before bed is 46% and the percentage of adults that read before bed is 54%. So, the group with the greatest percentage was the adults.
I hope this helps!
Answer:
C
Step-by-step explanation:
Given
+ 
← factor the denominator of first fraction
= 
+
Multiply the numerator/ denominator of second fraction by (x + 2)
= + 
The denominators are now common, so add the numerators leaving the denominator, that is
= 
= 
→ with numerator 4x + 6 → C
V (7,9) would make PRTV a square
