Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Let the price of the room be p

Let the size of the room be s

To find the size of a kitchen that costs $3,824.00 we must first find the relationship between them

The statement

The price of tiling a room varies directly as the size of the room is written as

<h3>p = ks</h3>

where k is the constant of proportionality

when

p = $4,224.00

s = 264 square feet

Substitute the values into the expression to find k

That's

4224 = 264k

Divide both sides by 264

k = 16

So the formula for the variation is

<h3>p = 16s</h3>

when

p = 3824

s =  \frac{p}{16}

s =  \frac{3824}{16}

s = 239

The final answer is

239 square feet

Hope this helps you

Suppose Y(t) = 25e^3t + 12 represents the number of bacteria present at time t minutes. At what time will the population reach 1
Levart [38]

Given:

The given function is:

Y(t)=25e^{3t}+12

Where Y represents the number of bacteria present at time t minutes.  

To find:

The time taken by bacteria population to reach 100 bacteria.

Solution:

We have,

Y(t)=25e^{3t}+12

Putting Y(t)=100, we get

100=25e^{3t}+12

100-12=25e^{3t}

88=25e^{3t}

Divide both sides by 25.

\dfrac{88}{25}=e^{3t}

Taking ln on both sides, we get

\ln (\dfrac{88}{25})=\ln e^{3t}

\ln(\dfrac{88}{25})=3t                  [\because \ln e^x=x]

Divide both sides by 3.

\dfrac{1}{3}\ln(\dfrac{88}{25})=t

Therefore, the required time is \dfrac{1}{3}\ln(\dfrac{88}{25}) minutes.

Factor completely 2r²-32​
diamong [38]

Answer:

2(r+4)(r-4)

Step-by-step explanation

First, you want to factor out 2 from both terms, which gives you 2(r^2-16). Then you want to recognize that (r^2-16) is factorable into 2 terms. If you multiply (r+4) by (r-4) then you are given (r^2-16) as a result.

kari74 [83]

Answer:

  x = -6

Step-by-step explanation:

Maybe this means you want to solve ...

  -3x -8 = 10

  -3x = 18 . . . . . add 8 to both sides

  x = -6 . . . . . . . divide both sides by -3
