Answer:

e = -2

Step-by-step explanation:

from the question we are required to solve for the value of e. to solve for e is very simple but always take note of the positive and negative sign for accuracy in your result.

9e-7=7e-11

collect the like terms

9e- 7 - 7e = -11

9e - 7e = -11 + 7

2e = -4

divide both sides by the coefficient of e which is 2

2e/2 = -4/2

e = -2

to check if your answer is correct put the value of e into the question and see if your right hand side equals your left hand side

9e-7=7e-11

9(-2) - 7 = 7(-2) - 11

-18 - 7 = -14 - 11

-25 = -25

Answer:

e = -2

Step-by-step explanation:

9e-7=7e-11

Subtract 7e from both sides

9e-7e -7=7e -7e-11

2e -7 = -11

Add 7 to each side

2e -7+7 = -11+7

2e = -4

Divide each side by 2

2e/2 = -4/2

e =-2

A tile factory earns money by charging a flat fee for delivery and a sales price of $0.25 per tile. One customer paid a total of
Alona [7]
Flat fee is computed by:

The sales price of each tile is 0.25 and the customer only bought 10,000 tiles.
So, $0.25 x 10,000 = $2500
So the total sales price per tile sold was $2,500.

The buyer paid $3,000, so the flat fee was included there.
So, $3,000 - $2,500 = $500

So the flat fee was $500.
~
The revenue function is the total income from producing the units. And it has a equation of: R(x) = price per unit x number of units sold plus any fee that is included

So the function describing the revenue of the tile from this sale is:
R(x) = 0.25x + 500

Sam bought brushes for $8, a palette for $5, and oil paints for $15. He paid $29.82 in all. What sales-tax rate did Sam pay?
klio [65]
Total purchased w/o tax: $8 +$5 + $15 = $28
He paid (w/tax) $29.82 so 
$ 29.82 - $28 = $1.82 (sale tax)

Now we need to find the sales tax rate:

$1.82 / $28 * 100 = 0.065 *100% = 6.5%

Double check:

$28 *6.5 / 100  = $1.82

$28 + $ 1.82 =  $29.82 total amount he paid..

So the sales tax rate is 6.5%
