ra1l [238]

Answer:

Common ratio is 3

The three terms are 162, 486, 1458

Step-by-step explanation:

Given: The first 4 terms of a sequence are 2,6,18,54

To find:

A. the common ratio

B. the next 3 values in the geometric sequence

Solution:

Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.

A.

\frac{6}{2}=3\\\\\frac{18}{6}=3\\\\\frac{54}{18}=3

So, the common ratio is 3

B.

The next three values are as follows:

54(3)=162\\162(3)=486\\486(3)=1458

HELP!!Part B What is the approximate volume of each slice that Hattie's grandma cut? (arc length of each slice is 3 in, vol. of
GalinKa [24]

The approximate volume of each slice will be 63.5 inch². The total cake is divided into the four cylindrical slice.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

The volume of the slice is;

\rm V = \pi r^2 h\\\\\ \rm 81 \pi = \pi  \times (r)^2 \times 4 \\\\ r= 4.5 \ inch

If the grandma cut four pieces, is the approximate volume of each slice that Hattie's grandma cut will be;

The approximate volume of each slice will be;

\rm V = \PI r^2 h \\\\ \rm V = 3.14 \times (4.5)^2 \times 1 \\\\ V=63.5 \ inch^2

Hence, the approximate volume of each slice will be 63.5 inch².

Name the prism in each case given that all lateral faces are rectangles and the bases are: Equilateral triangles
Cloud [144]
This is a triangular prism.

The lateral faces are triangles; this means that the two bases are parallel to one another.  This makes it a prism instead of a pyramid.

The bases being triangles makes it a triangular prism.

Mr. Perkins wants to rent a car for a day. It will cost the daily fee of $75 plus $0.55 per mile driven, which expression shows
Alla [95]

Answer:

B. 75 + 0.55m

Step-by-step explanation:

We know that the constant is $75. You only pay this once.

Whereas $0.55 you pay per mile. Which means that you will multiply 0.55 by how many miles you drive.

This means that the equation will look like:

75 + 0.55m

Hope this helps! :)
