Answer:

There are 19.5 extinguishers needed.

Step-by-step explanation:

Given that,

One fire extinguisher be available for every 4,520 square feet in a building.

We need to find the value of x if the number of fire extinguishers needed for a building that has 88,140 square feet.

x = (Area of building)/(Area of one fire extinguisher)

So,

x=\dfrac{88140}{4520}\\\\x=19.5

So, there are 19.5 extinguishers needed.

Write equations to solve these problems
dangina [55]

Answer:

Step-by-step explanation:

a) 60 = 50x

x = 60 / 50 = 1.20

1.20(100) = 120%

b 50 = 60x

x = 50/60 = 0.83333....

0.83333(100) = 83.333... % or 83⅓%

horsena [70]

Answer:

$6.25

Step-by-step explanation:

1. Variables

Let's the variable for socks will be s

2. Set up an equation

21.75 + 3s = 40.50

3. Subtract 21.75 from both sides

3s = 18.75

4. Divide 3 from both sides

s = $6.25

Presumably, h(x)=3(5)^x. In that case,

(A)
The average rate of change over the interval 0\le x\le1 is

\dfrac{h(1)-h(0)}{1-0}=\dfrac{15-3}1=12

and over 2\le x\le3, it's

\dfrac{h(3)-h(2)}{3-2}=\dfrac{375-75}1=300

(B)
\dfrac{300}{12}=25, i.e. the average rate of change over the second interval is 25 times higher. That's to be expected; 3(5)^x is an exponential function. As x gets larger, the rate of change of h(x) gets larger too.
