Hack way
25%=1/4
13 is 1/4 of something
1/4 times 4=4/4=1
therefor
13 times 4=1 whole
13*4=52
the original number is 52
Answer:
-27.26 ----------- -52.89 - (-25.63)
135.03 ----------- 49.40 - (-85.63)
-120(2)/(3) ----------- -96(2)/(9) - 24(4)/(9)
-15(3)/(5) ----------- -18(1)/(5) - [-2(3)/(5)]
Answer:
I believe that the answer is over by 3,-1
Step-by-step explanation:
and also is there any a,b,c,d, multiple choice answers?
Answer:
8835.73ft^3
Step-by-step explanation:
First:
Find area of the base circle.
Diameter is 15, so radius is 7.5
Area of the base circle is 56.25pi (use formula: A=pi(r)^2 ) (also ill convert pi into decimals only later)
next find the volume of the cylinder
height is 40 so volume = 56.25pi*40 = 2250pi
next find the volume of the dome at the top.
you know the radius is 7.5
Use volume of sphere formula below :
4
/3πr^3
=1767.15
alright now add the two bolded values
1767.15+2250pi
= 8835.73
hope this helps
Your answer would be postulates.
