Answer:

75

Step-by-step explanation:

We line up the tens place of 33 and 42 as well as the ones place so that it looks like:

33

+42

--------

Then we add first the ones, which is 3 + 2 for 5. Then we add the tens together, 3 + 4 is 7. We put the five first since its in the ones place and the 7 second since its in the tens place for 75.

Jacob is renting an auger (used to drill holes for posts). On Home Depot's website, the charge is $65 plus $7 per hour. At Lowes
Butoxors [25]

Answer:

10 hour rental

Step-by-step explanation:

Let x = number of hours

HD cost: 7x + 65

L cost: 4x + 95

Set the two cost expressions equal and solve for x, the number of hours.

7x + 65 = 4x = 95

3x = 30

x = 10

The costs are equal for a 10 hour rental.

Given

\{3,10,90,108\}

3x +3= 33

Required

Which is true for x

Explain how the Quotient of Powers Property was used to simplify this expression.
Simora [160]

Answer:

The answer is option 2, by simplifying 9 to 3² to make both powers base 3 and subtracting the exponents.

Step-by-step explanation:

You have to make the expressions into the same base :

\frac{ {3}^{4} }{9}  =  \frac{ {3}^{4} }{ {3}^{2} }

Next, you have to apply Indices Law :

{a}^{m}  \div  {a}^{n} \: ⇒ \: {a}^{m - n}

{3}^{4}  \div  {3}^{2}

=  {3}^{4 - 2}

=  {3}^{2}

Use slope formula to find the missing coordinate.<br><br> (r, 1) and (5, -7) Slope = 8/3
Lena [83]

Answer:

r=8

Step-by-step explanation:

The formula for slope is

m = (y2-y1)/ (x2-x1)

Substitute in what we know.

8/3 = (-7-1)/(5-r)

Simplify

8/3 = -8/(5-r)

We can use cross products to help us solve.

8 * (5-r) = 3 * (-8)

divide each side by 8

8/8 * (5-r) = 3 * (-8)/8

5-r = -3

Subtract 5 from each side

5-r-5 = -3-5

-r = -8

Multiply by -1

r = 8

Step-by-step explanation:

\sqrt[8]{8*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y}

Since there are eight y's in two groups we can take them out which turns into

y^2\sqrt[8]{8}
