Paige works at a department store and has a commission rate of 3 percent. Her sales for the quarter were $4,596. If she earns $5

vagabundo [1.1K]

If she gets 3% of what she sells you multiply the decimal form of the percent by the amount she has made:
50*.03=1.5
So she make $1.50 for every $50 of sales, so you multiply the amount she made by her commission each day by the number of days she worked:
1.5*30=45

She earned a total of $45<span />

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)

so

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

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

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

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

Give that T = 37v/6v-5.4m a. Make V the subject of relation b. If T = 4.5 and M =7x10(7),calculate the value of v , leaving your

PilotLPTM [1.2K]

Answer:

$v = \frac{5.4mT}{6T - 37}$

$v = -1.701*10^8$

Step-by-step explanation:

Given

$T = \frac{37v}{6v-5.4m}$

Solving (a): Make v the subject

$T = \frac{37v}{6v-5.4m}$

Cross Multiply:

$(6v-5.4m)T = 37v$

Open bracket

$6vT - 5.4mT = 37v$

Collect Like terms

$6vT - 37v= 5.4mT$

Factorize:

$(6T - 37)v= 5.4mT$

Make v the subject

$v = \frac{5.4mT}{6T - 37}$

Solving (b):

$T = 4.5$

$m = 7 * 10^7$

So, the expression becomes:

$v = \frac{5.4mT}{6T - 37}$

$v = \frac{5.4*7*10^7*4.5}{6*4.5 - 37}$

$v = \frac{170.1*10^7}{27 - 37}$

$v = \frac{170.1*10^7}{-10}$

$v = -17.01*10^7$

$v = -1.701*10*10^7$

$v = -1.701*10^8$
