Two smaller triangle have areas of 75 m square and 12 m squared. find the ratio of their perimeters

Paul [167]

we know that two similar triangles will have ratio corresponding side is same.

ratio triangle 1 is 75m^2.

and triangle 2 is 12m^2.

$75:12=\frac{75}{12} =\frac{25}{4} .$

so we have ratio of area $25:4$ .

ratio of perimeter will be $\frac{25}{4} =\frac{50}{8} =\frac{25}{12}$ .

from these perimeter ratio also $\frac{25}{4} =25:4$ .

A cab company charges according to the following rate chart. Which graph correctly represents the charge, y, in dollars for a ca

77julia77 [94]

The graph is the one that correctly represents the linear piece-wise function is the first graph.

<h3>How to solve for the graph</h3>

First we have a linear function as

Mx + b

mc= slope, this is the rate of change, how y changes as x changes by 1.

b = y-intercept, y value as x = 0

y = 5 + x

x ≤ 10

at 10 we have 5 + 10 = 15

at 2 dollars

y = 15 + 2(x - 10)

at 14

y = 15 + 2(14 - 10)

15 + 2*4

= 23

Hence we can conclude that the first graph here is the correct one.
