Answer:

$480

Step-by-step explanation:

Perry makes 15% commission for each TV he sells.

How much would he have to sell a TV to get $72

First of all, let's call the unknown variable x

So 15% of x= $72

Mathematically, this would be represented as 15/100 * x= 72

15/100x= 72

Breaking down further,

15/100 can be broken down to 3/20

3/20x= 72

So to find the value of x, we divide both sides by 3/20

x= 72 ÷ 3/20

x= 72 * 20/3 (using the law of indices)

x= 1440/3

x= $480 dollars.

So, Perry would have to sell a TV for $480 to make a $72 commission.

A ramp was constructed to load a truck. If the ramp is 10 feet long and the horizontal distance from the bottom of the ramp to t
NeX [460]

Pythagoras theorem is a basic relationship in geometry between the three sides of a right triangle. The height from the ground to the top of the ramp 6. 0 ft. Option D is correct.

<h3>What is the  Pythagoras theorem?</h3>

Pythagoras theorem is a basic relationship in geometry between the three sides of a right triangle.

It indicates that the area of the hypotenuse square is equal to the sum of the areas of the squares on the other two sides.

The given data in the problem will be;

L is the length of ramp=  10 feet

x is the horizontal distance from the bottom of the ramp = 8 feet

h is the height from the ground to the top of the ramp=?

According to Pythagoras theorem,

\rm H^2=P^2+B^2 \\\\  \rm l^2=h^2+X^2 \\\\ \rm 10^2=h^2+8^2 \\\\ \rm h=\sqrt{100-64 }  \\\\ \rm h=36 \\\\  \rm h=6 ft

Hence the height from the ground to the top of the ramp 6. 0 ft. Option D is correct.

The distance between the baseball stadium and the airport is 1.6×10^6 centimeters.Which unit of measurement is most appropriate
Ad libitum [116K]

Answer:

<em>'Kilometers' is the most appropriate unit to measure this distance. </em>

Step-by-step explanation:

The distance between the baseball stadium and the airport is  1.6\times 10^6 centimeters.

(1.6\times 10^6)cm = (16\times 10^5)cm

Now,  <u>10⁵ centimeters is equal to 1 kilometer</u>.

That means,  (16\times 10^5)cm = (16\times 1)km= 16 km

So, 'Kilometers' is the most appropriate unit to measure this distance.

Write a function in terms of t that represents the situation. A company profit of $20,000 decreases by 13.4% each year
Thepotemich [5.8K]

Answer:

P(t)=20000(0.866)^{t}

Step-by-step explanation:

we can use formula

P(t)=P_0(1-r)^{t}

where

P(t) is the profit after t years

Po is initial profit or profit is at t=0

r is decreasing rate

t is time in years

we are given

A company profit of $20,000 decreases by 13.4% each year

so,

Po=20000

r=13.4%=0.134

now, we can plug values

P(t)=20000(1-0.134)^{t}

we get

P(t)=20000(0.866)^{t}
