A school bus requires 40 liters of fuel per week. If your school district runs 5,000 school buses, how many liters of fuel will
Butoxors [25]

Answer:

C. 10.4 million liters.

Step-by-step explanation:

1. First, you want to create an equation to help you solve this.  You know that there are 5,000 school buses and they use 40 liters of fuel per week.  So, you know that 5,000 · 40x would be the amount of fuel for x weeks (where x is the number of weeks).

2. To figure out how many liters would be used in 52 weeks, simply put 52 in for x.  So, the expression is 5,000·40(52).

3.  Multiply 40(52) to get 2,080.  Your expression now looks like this: 5,000·2,080

4. Multiply 5,000(2,080) to get your answer of 10,400,000 liters.

Hope this helps! :) If you could give me Brainliest that would be super helpful!

Find the coordinates of the points that are 10 units away from the origin and have a y- coordinate equal to -8
MrRissso [65]

Answer:

(-6, -8) and (6, -8)

Step-by-step explanation:

Think of this as a right triangle

The hypotenuse is 10

The "y" leg is |-8| = 8

x² + 8² = 10²

x² + 64 = 100

x² = 36

x = ±6

two points

(-6, -8) and (6, -8)

Hello from MrBillDoesMath!

Answer:  6 * p^(3/2) * q^4


Discussion:

We are evaluating

sqrt  { 36 * p^3 q^8 }

where "sqrt" indicates the square root and the ^ (as in q^8) means "raised to the power of:

The square root of the product is the product of the square roots. (Say that 5 time out loud quickly!). So the above equation becomes

sqrt  { 36 * p^3 q^8 }  =

sqrt( 36) * sqrt( p^3) * sqrt (q^8)

The square root of 36 is 6 as 6* 6 = 36 so the equation equals

6 *  p ^ (3/2) * q^ (8/2)        

Note that  the square root of a number, for example, r, is the same as raising the number to the (1/2) power.  That's where the (1/2) terms came from above.

But 8/2 = 4 so the equation simplifies to

6 * p^(3/2) * q^4



Thank you,

MrB
