write as single power of 7?

(7^2)^-2​

Answers

Answer 1

Answer:

[tex]7^{-4}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

[tex](7^2)^{-2}[/tex]

= [tex]7^{2(-2))}[/tex]

= [tex]7^{-4}[/tex]

u=8

3u+5u=64

8u=64

u=8

finish

Hey there!

FIRST: you have to SIMPLIFY BOTH SIDES of your given EQUATION (there’s approximately 3 ways but we will use 2)

• 3u = 64 – 5u

• 3u = –5u + 64

SECOND: ADD by 5u on BOTH SIDES

• 3u + 5u = –5u + 64 + 5u

• CANCEL: –5u + 5u because that gives you 0

• KEEP: 3u + 5u because it can help us solve for you u-value

“3u + 5u = 8u”

New equation: 8u = 64

THIRD: DIVIDE by 8 on BOTH SIDES

• 8u/8 = 64/8

• CANCEL out: 8u/8 because that gives you 1

• KEEP: 64/8 because that gives you your u-value

“64/8 = u”

“64/8 = 8”

• Therefore your ANSWER: u = 8 ☑️

Good luck on your assignment and enjoy your day!

For a school picnic, leslie ordered a box of fresh-baked gingerbread cookies and sugar cookies. She got 60 cookies in all. 15 of the cookies were gingerbread. What percentage of the cookies were gingerbread.

Answers

Answer:

Pretty sure 25%.

Step-by-step explanation:

First, you would need to see how many times 60 goes into 100, because a percent is ALWAYS over 100. You should get an answer of 1.66666667. Then you if you multiply it to one of the numbers then you have to do it to the other number. So, you would do 15 times 1.66666667. You would get 25. So, that would be 25 over 100 or 25/100. And 25 over 100 is 25%.

I hope I helped! :) Sorry if it's wrong :(

Answer:

∠ EBF = 40°

Step-by-step explanation:

Given BF bisects ∠ CBE , then

∠ CBF = ∠EBF , substitute values

7x - 2 = 6x + 4 ( subtract 6x from both sides )

x - 2 = 4 ( add 2 to both sides )

x = 6

Thus

∠ EBF = 6x + 4 = 6(6) + 4 = 36 + 4 = 40°

In a candy store in California using a 6% tax sale, three jars of candy are labeled $35.00 after tax. What is the sale price of each jar of candy after tax?

Answers

Answer:

Step-by-step explanation:

You first have to find 6% of 35. Which is 2.1 and so you then multiply 2.1×3 which is 6.3 and then subtract 6.3 from 35. 35-6.3 which is 28.7 and then divide that by 3. Which is essentially 9.6 if you round up the decimal. Otherwise it'd just be 9.566667. So, I'd say each is 9.6 or 10 if you're rounding for the nearest whole number.

Chris is at the florist and wants to buy flowers. Arrangements of daisies are $4.25 and the arrangements of roses are $6.50. He wants to spend less than $39 and wants to buy at least 4 arrangements.

Answers

Answer:

Let's define the variables:

D = arrangements of daisies that he buys

R = arrangements of roses that he buys.

Each arrangement of daisies costs $4.25, then for D of them, the total cost is:

D*$4.25

And for the roses, the cost of each one is $6.50, then the cost for R of them is:

R*$6.50

We know that he wants to spend less than $39, then we have the inequality:

D*$4.25 + R*$6.50 < $39

And we also know that he wants to buy at least, 4 arrangements, then:

D + R ≥ 4

Now we have a system of inequalities:

D + R ≥ 4

D*$4.25 + R*$6.50 < $39

This has quite a few solutions, for example, he could buy 3 arrangements of daisies and 2 of roses, the total cost would be:

3*$4.25 + 2*$6.50 = $25.75, which is less than $39, and he is buying 5 arrangements, more than 4 as he wanted.

And there are a lot of other possible options.
