Factoring this out will be: (a-5) (a+4)
Answer:
the answer is c) 182.25
Step-by-step explanation:
The information provided gives you a scale that will ultimately allow you to determine the height of the larger cylinder.
Since it tells us the two are similar, we can use the scale to solve for the second height.
Set up your math like this:
h represents the height you are trying to find.
using a common multiple, you can solve for h.
16 times 4 is 64. so 729 divided by 4 is 182.25

To calculate for the percent of decrease:
First: work out the difference between the two numbers that you are given with.
Decrease = Original Number - New Number
Second: divide the decrease by the original number and multiply the answer by 100.
In formula terms it would look like this percent of decrease = Decrease ÷ Original
Number × 100
= (87-75) / 87 x 100
= 12/87 x 100
= 0.137931034 x 100
=13.79%
Answer:
The sum of its 30 terms is 38167.5
Step-by-step explanation:
Given:
The First term in the AP is -504
The Sum of its 9 terms is -126
To Find:
The sum of its 30 terms = ?
Solution:
The sum of n terms of an AP:
The sum of 9 terms of an AP:
(-4536) +36d = -126
36 d = -126+4536
36 d= 4410
d = 122.5
The sum of its 30 terms is
