Answer: 18
Step-by-step explanation:
Evaluate 7 r − 15 /s
Given that r = 3 and s = 5
7r - 15/s
Substitute 3 for r and 5 for s in the above expression
7(3) - 15/5
= 21 - 3
= 18

Answer:
Step-by-step explanation:100,60,36
hello :
the common ratio in the sequence:100,60,36 ( geometric sequence )
is : r = 60/36 = 36/100 = 0.6 the first term is : A1= 100
the n-ieme term is : An= A1× r ^(n-1)
An = 100× (0.6) ^(n-1)
the 6th term is : A6 = 100×(0.6)^5
The volume of pyramid B (3,136 in.³) is 323% bigger than the volume of pyramid B (972 in.³).
<h3>What is the Volume of a Square Pyramid?</h3>
Volume of square pyramid = 1/3(a²)h
Given the following:
- Volume of pyramid B = 3,136 in.³
- Base side length of pyramid A (a) = 18 in.
- Height of pyramid A (h) = 9 in.
Volume of square pyramid A = 1/3(a²)h = 1/3(18²)9 = 972 in.³
3,136/972 × 100 = 323%
Pyramid B volume is 323% bigger than the volume of pyramid A.
