When you raise an exponent to another exponent, you multiply the exponents. (7^2)^3 = 7^(2 x 3) = 7^6.

When you multiple 2 number with different exponents but same base, you add the exponents.

7^6 x 7^0 = 7^(6 + 0) = 7^6

And so....

<h2><u>7^6 is the answer!</u></h2><h3>(7 to the exponent of 6)</h3>

Svetach [21]

to increase each dimension by equal lengths so that its area triples is 12 feet.

The given dimensions are 18 feet by 15 feet.

We need to find how much should each dimension increase.

Shaquana wants to increase each dimension by equal lengths so that its area triples.

Let the increased length be x.

So, length =18+x feet and width=15+x feet.

As we know, the area of a deck=Length×Width

The original area of a deck=18×15=270 square feet.

Now, the new area of a deck=(18+x )×(15+x)=3×270

⇒270+15x+18x+x²=810 square feet

⇒x²+33x-540=0

Here, a=1, b=33 and c=-540 in $x=\frac{-b\±\sqrt{b^{2-4ac} } }{2a}$ .

⇒ $x=\frac{-33\±\sqrt{33^{2} -4 \times (-540)} }{2 \times 1}$

⇒ $x=\frac{-33\±\sqrt{1089 +2160} }{2 \times 1}=\frac{-33\±57}{2}$

⇒x=-45 or x=12

Length can not be a negative integer.

Therefore, to increase each dimension by equal lengths so that its area triples is 12 feet.

Chris purchased a new mattress for $1,399. he will need to pay $78 each month on his interest-free loan to pay off the total pri

viva [34]

At least 24 times he need to deposit $ 50 to paying off his total purchase.

<h3>What is Savings?</h3>

Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.

Here, cost of mattress = $ 1399

cost of EMI = $ 78

Duration of EMI = 18 months

Total payable amount = 18 X 78

= $ 1404

Current account balance = $ 250

Per month savings = $ 50

Duration at which total balance is equivalent to payable amount

= (1404 - 250)/50

= 1154/50

= 23.08

Thus, At least 24 times he need to deposit $ 50 to paying off his total purchase.

Factory produces 6 motorcycles in 9 hours determine how many hours it takes to produce 16 motorcycles at this rate

LUCKY_DIMON [66]

So 6 is to 9
6:9
16 is to x
16:x
they are eual so change to fraction and solve
6/9=16/x
multiply both sides by x

6x/9=16
multil yboth sides y 9
6x=144
divide by 6
x=24
answer is 24 hours
