A city employee paints curbs in parking lots and replaces road signs. It takes 0.5 hour to paint a parking lot curb and 2.5 hour

Genrish500 [490]

Question is incomplete. Here is the complete question.

A city employee paints curbs iin parking lots and replaces road signs. It takes 0.5 hour to paint a parking lot curb and 2.5 hours to replace a road sign. The function below can be used to find c, the number of parking lot curbs the employee paints when he replaces r road signs in a 40-hour workweek.

$c=\frac{40-2.5r}{0.5}$

If the employee painted 20 curbs in one week, how many road signs did he replace that week?

a) 20 b) 30 c) 0 d) 12

Answer: d) 12

Step-by-step explanation: In one week, the employee painted 20 curbs.

c is the number of curbs painted in one week, so: c = 20

$20=\frac{40-2.5r}{0.5}$

$40-2.5r=20*0.5$

$-2.5r=10-40$

$-2.5r=-30$

$r=\frac{-30}{-2.5}$

r = 12

In one week, the employee replaced 12 road signs.

Fter completing the fraction division 7/3 : 2/9 , Bai used the multiplication below to check his work.

Vitek1552 [10]

First off all, let's find
$\dfrac{7}{3} : \dfrac{2}{9} = \dfrac{7}{3} \cdot \dfrac{9}{2}= \dfrac{63}{6} = \dfrac{21}{2}$ .

This shows that Bai found the correct quotient.

If $a:b=c$ , then $a=c\cdot b$ . Using this rule, you have to check that $\dfrac{7}{3}$ is equal to product $\dfrac{21}{2} \cdot \dfrac{2}{9}$ .

Thus, Bai checked his work using multiplication correctly.

Answer: Correct choice is A.

What does the Exponential Decay Variables Mean? For Half Lifes Y=Ae^-bX

kompoz [17]

A is the initial population

b is the decay coefficient

X is normally the time.

$Y = Ae^{-bx}$

then is the population half of the initial population of A

for half life you will have

$\frac{Y}{A} = \frac{1}{2}$

so the equation becomes

$\frac{1}{2} = e^{-bX}
\\
\\\ln{ \frac{1}{2}} =\ln{e^{-bX}}
\\
\\ \ln{1}-\ln{2}=-bX
\\bX=\ln{2}$
