We know that Ms Salazar's car wastes on average 25 miles per gallon of gasoline.

We also know that she filled the 10 gallon tank with gasoline, before travelling 200 miles. We are going to find the amount of gasoline she will have left, after the journey.

As salazar wastes 25 miles per gallon, we obtain:

$x=\frac{200 mi .lg}{25mi} =8g$

and she will waste 8 gallons by travelling 200 miles

This means that she will have left 2 gallons after the journey.

If ab = c - d, which of the following is an expression for d in terms of a, b, and c?

horsena [70]

ANSWER

$d = - ab + c$

EXPLANATION

The given expression is

$ab = c - d$

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.

This means that, we need to isolate d on one side of the equation while all other terms are on the other side.

We subtract from both sides of the equation to obtain,

$ab - c = - d$

We now divide through by -1, to get,

$- ab + c = d$

Or

$d = - ab + c$

Evaluate i^31 please help

Nadya [2.5K]

ANSWER

${i}^{31} = - i$

EXPLANATION

We want to evaluate

${i}^{31}$

Use indices to rewrite the expression as:

$= {i}^{30} \times i$

We know that

${i}^{2} = - 1$

So we rewrite the expression to obtain;

$= ({ {i}^{2}) }^{15} \times i$

This gives us;

$= {( - 1) }^{15} \times i$

This simplifies to

$= - 1 \times i$

$= - i$

Help me asap please!!!

Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that
$\sqrt{72}$ (<span>8.4852...)
</span>is equal to
$2* \sqrt{36}$ (12)

If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.

So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!

Kenny buys 4 1liter bottles of water how many millileters of water does Kenny buy

kenny6666 [7]

Kenny bought 4 1liter bottles of water

1liter is equal to 1,000 milliliters (milli means 1,000)

What that means is that in each bottle of water that he purchased, he has 1,000 milliliters

He has 4 bottles, so we simply take

4(bottles) x 1,000(amount of water in each bottle)

4 x 1,000 = 4,000 milliliters

Sophia puts $250 in the bank with a 2.5% annual interest rate compounded monthly. If Sophia does not touch his money, how much m

Fittoniya [83]

Answer:

Step-by-step explanation:

Deposited amount initially (P) = $250.

Rate of interest(r) = 2.5% compounded monthly = 0.025

Number of years (t) = 4.

Number of months in an year (n) = 12.

Formula for compound interest:

$A=P(1+\frac{r}{n})^{nt}$ .
