PLease help . . . . . . . .
blagie [28]

Traveling m miles on this taxi costs

c=2.5+3.25m

In fact, we spend 2.50 no matter what, and then we add 3.25 (i.e. the cost of a mile) multiplied by the number of miles.

This quantity has to be less than or equal to 61, so we have

2.5+3.25m\leq 61

Solving for m, we start by subtracting 2.5 from both sides:

3.25m\leq 58.5

Then, we divide both sides by 3.25:

m\leq 18

Besides math name a reason why someone would need to find the volume of a cone, and a prism?
storchak [24]

Answer:

The volume of a cone is given by the equation:

V=\frac{1}{3}\pi r^2 h

where

r is the radius of the cone

h is its height

We have several examples of cones in real life: for instance, the cone of an ice-cream, it has a conic shape.

The volume of a prism instead is given by:

V=lwh

where:

l is the length of the base

w is the width of the base

h is the height of the prism

Again, we have several examples of prisms in daily life: for example, boxes have usually the form of a prism, so it can be useful to know their size in order to calculate their volume.

Last year, Lien earned $1,600 more than her husband. Together they earned $51,000. How much did each of them earn?
jok3333 [9.3K]

HELP±! FAST<br><br>What is the scale factor?
cupoosta [38]

Given that the triangles are similar then the ratios of corresponding sides are equal.

To determine the scale factor calculate the ratio of corresponding sides, that is

\frac{NO}{GH} = \frac{15}{9} = \frac{5}{3}
