Answer:
1. 3:1
2. also 3:1
Step-by-step explanation:
ratio has nothing to do with measurements
Answer:

Step-by-step explanation:
Notice that the series: 1 - 3 + 9 - 27 +... clearly has powers of the factor 3 in its terms and it is also an alternate series (the terms alternate from positive to negative). The terms are positive for
(even terms) , while the odd terms
are negative. (so most likely there should be a factor (-1) in the common ratio.
We can then represent it with the following summation expression:
given that each of its first four terms are:

Answer: 12,8 approximately 13 cones
Step-by-step explanation:
1] volume of a cone
V=1/3πr^2h
V=1/3π(3)^2(5)
V=47,12 cubic inches
2] volume of a cylinder
V=πr^2h
V=π(8)^2(3)
V=603.19
Now devide the volume of a cylinder by the volume of a cone
603,19÷47,12=12,8 cones
Answer:
-x - 29
Step-by-step explanation:
-2(5x + 1) + 3(3x - 9) = First, distribute the numbers in the parenthesis
-10x - 2 + 9x - 27 = Then, combine like terms
(-10x + 9x) + (-2 - 27)= Next, distribute the digits
-x - 29
