The function C(f) = (f – 32) converts a temperature, f, in degrees Fahrenheit, to a

Vera_Pavlovna [14]

That function is incorrect.
The correct function is . . . . C(f) = (5/9) (f - 32) .

If a Fahrenheit thermometer reads 52° ,
then a Celsius thermometer should read . . .

C (52) = (5/9) (52 - 32) =

(5/9) (20) = <em>(11 and 1/9)°C</em>.

A right cylinder has a radius of 6 m and a surface area of 84 m². Find the surface area of a similar cylinder with a radius of 2

dlinn [17]

Answer:

The surface area of the second cylinder is equal to $9.33\ m^{2}$

Step-by-step explanation:

we know that

If two figures are similar then

the ratio of their surfaces areas is equal to the scale factor squared

Let

z-------> the scale factor

x------> the surface area of the smaller cylinder (second cylinder)

y-------> the surface area of the original cylinder (first cylinder)

$z^{2}=\frac{x}{y}$

Step 1

Find the scale factor

$z=\frac{2}{6}=\frac{1}{3}$

Step 2

Find the surface area of the second cylinder

we have

$z=\frac{1}{3}$

$y=84\ m^{2}$

substitute and solve for x

$(\frac{1}{3})^{2}=\frac{x}{84}$

$x=\frac{1}{9}*84=9.33\ m^{2}$

gladu [14]

Answer:

12 rides

Step-by-step explanation:

First, get the total and subtract it from the expenses.

34 - 8.50 - 4.50 = 21

Then divide the answer by how much each ride costs to find the answer

21 ➗1.75 = 12

So Sam can ride 12 rides.
