15% of $70 =$10.5.

You would do
15x70=1050
1050/100 because a percent is always equal to 100
1050/100=10.5

Christian purchased a new car. The value of the car is depreciating at a
LenKa [72]

18000 represents the price of the new car.

The value of the car in 6 years can be found by substituting 6 for the variable t, as follows:

V = 18000(1-.12)^6\\V = 18000(0.4644)\\

In 6 years, it will be worth around $8359.27.

The equation for the car worth $20000 is this:

V = 20000(1-.15)^6\\V = 20000(0.3771)\\

In 6 years, the other car will be worth $7542.99, so the car worth $18000 will have more value in 6 years.

The U.S. annual energy consumption is roughly 1 x 1020 joules per a year. If there are 350,000,000 people in the U.S., express t
AnnZ [28]

Answer with Step-by-step explanation:

Given the total energy consumption for all of the population is

E=1\times 10^{20}Joules

Thus energy consumed by each person per year can be obtained by dividing the total energy consumed by the total population Thus we get

E_{per\cdot person}=\frac{1\times 10^{20}}{350\times 10^{6}}\\\\E_{per\cdot person}=28.57\times 10^{10}Joules/Year

Now the energy consumed in each second assuming that there are 365 days in each year equals

E_{second}=\frac{28.57\times 10^{10}}{365\times 24\times 3600}\\\\E_{second}=9059.49Joules

Do the side lengths 15,20 and 25 form a right triangle?<br><br><br> PLEASEEEE HELPPPP!!! asap
sveticcg [70]
<h3>Answer: Yes, those sides form a right triangle</h3>

===================================================

Work Shown:

a^2+b^2 = c^2

15^2+20^2 = 25^2

225+400 = 625

625 = 625

Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.

Side note: c is always the longest side.

Vocabulary: What does it mean for an equation to express y in terms of x?
Vika [28.1K]
It means you have to express y in terms of x.
in other words it means you have to re write the equation so that y is in one side and x and some other numbers should be in the other side. 
example- y=2x+4 or
                y= 5x+6
