Answer:

its 42 the other answer is wrong

Step-by-step explanation:

First calculate how long it will take one person to paint one wall.

Hint #22 / 5

It will take \dfrac{1}{4}

start fraction, 1, divided by, 4, end fraction of the time to paint one wall. So it will take 888 minutes for 333 people to paint one wall.

Hint #33 / 5

For only one person, it will take 333 times as long, so it will take 8 \cdot 3 = 248⋅3=248, dot, 3, equals, 24 minutes for one person to paint one wall.

Hint #44 / 5

So, the number of minutes it will take for one person to paint 777 walls is 24 \cdot 7 = 16824⋅7=16824, dot, 7, equals, 168.

Hint #55 / 5

The number of minutes it will take for 444 people to paint 777 walls is 168 \div 4 = 42168÷4=42

Find an equation for the nth term of the sequence. -4, -16, -64, -256, ...

Andrews [41]

This is a geometric sequence with first term a1 = -4 and common ratio r = 4

so nth term = a1* r^(n-1)

= -4 *4^(n-1)

John is driving around town. When he reaches the gas station, he notes that he has traveled 20 miles. He reaches home 2 hours la

Troyanec [42]

Answer:

$d=5t+20$

Step-by-step explanation:

The equation that will model this situation will be of the form

$d=mt+b$

where $t$ is the time in hours john has traveled since the gas station, and $d$ is the distance.

Now we know that John has already traveled 20 miles when he is at the gas station, this means at $t=0$ , $d=20$ ; or

$20=m(0)+b$

$\boxed{b=20}$

Thus we have

$d=mt+20$ .

Now we need to figure out $m.$

When John reaches home 2 hours later he notes that he has traveled 30 miles, which means he has traveled 30 - 20 = 10 miles; thus we have

$m= \frac{\Delta d}{\Delta t} =\frac{10 miles}{2hours} =5$

$\boxed{m=5}$

Now we have the full equation:

$\boxed{d=5t+20}$
