Answer:
(2^2)(z^7)

Explanation:
The quotient rule states that if two powers have the same base and are on opposite places of a fraction (one is on the numerator, the other on the denominator), you subtract the exponents.

First looking at the powers with the bases of 2, 2^8 is the numerator and 2^6 is the denominator. When we subtract 8-6 we get 2, so 2^8/2^6 would simplify to 2^2.

Then, we look at the powers with the base of z. z^10 is the numerator and z^3 is the denominator. When we subtract 10-3 we get 7, so z^10/z^3 would simplify to z^7.

I hope this helps! Please comment if you have any questions:)

Answer:

The answer is (Choice C) It is just right.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water. Peggy made a 12-liter batch of iced tea with 90 tea bags. What will Kermit think of Peggy's iced tea? Choose 1 answer: (Choice A) It is too strong. (Choice B) It is too weak. (Choice C) It is just right.

Now, to find which of the choice is correct.

So, we find first the unit rate of Peggy's iced tea bags per liter:

If, Peggy made a 12-liter batch of iced tea with 90 tea bags.

Then, Peggy would made a 1-liter batch of iced tea with = $\frac{90}{12} =7.5\ tea\ bags.$

Now, to get the unit rate of Kermit's iced tea bags per liter:

If, Kermit made a 2 liter of iced tea with 15 tea bags.

Then, Kermit would made a 2 liter of iced tea with = $\frac{15}{2} =7.5\ tea\ bags.$

Thus, the quantity of tea bags per liter is same of both Kermit and Peggy.

Hence, Kermit will think of Peggy's iced tea that it is just right.

Therefore, the answer is (Choice C) It is just right.

110 is 60% of what number?

Zigmanuir [339]

Answer: 183.33

Step-by-step explanation:

We have, 60% × x = 110

or,

100

× x = 110

Multiplying both sides by 100 and dividing both sides by 60,

we have x = 110 ×

100

x = 183.33

If you are using a calculator, simply enter 110×100÷60, which will give you the answer.

Sladkaya [172]

Kian has to work with 6 square inches

Step-by-step explanation:

Given that the logo has to be created in a rectangular shape

Length = 3 inches

Width = 2 inches

We have to calculate the area of the given space to find out that how much area Kian will work with.

So,

$Area = Length*Width\\=2*3\\=6\ in^2$

Hence,

Kian has to work with 6 square inches

URGENT!! HELP! 25 POINTS FOR THESE QUESTIONS!

avanturin [10]

Answer:

The correct options are;

A. 120

B. 34

Step-by-step explanation:

The given parameters are;

Required to find how many of the permutations of 1, 2, 3, 4, 5, 6, have 1, 2, 3 arranged one after the other in the given order

Requirement to arrange 6 digits, 1, 2, 3, 4, 5, 6 in the order such that 1, 2, and 3 always appear in turn, they are as follows

When the first digit is 1, and the 2nd digit is 2 the number of ways of selecting the other digits is 24

Arrangement, Number of ways

1, 2, 3, 4, 5, 6, 24

1, 4, 2, 18

1, 4, 5, 2, 12

1, 4, 5, 6, 2, 6

4, 1, 2, 18

4, 1, 5, 2, 12

4, 1, 5, 6, 6

4, 5, 1, 2, 12

4, 5, 1, 4, 2 6

4, 6, 5, 6

Total = 24 + 18 + 12 + 6 + 18 + 12 + 6 + 12 + 6 + 6 = 120 ways

The correct option is A. 120

2. The dimensions of the original rectangle = L by W

The dimensions of the lager rectangle = 1.5·L by 2·W

1.5·L × 2·W = 30

Given that L > W

∴ L×W = 30/(1.5 × 2) = 30/3 = 10

The possible integers that have a product of 10 are;

1 × 10 and 5 × 2

Therefore, since L > W, The dimensions of the larger rectangle are either 15 by 2 or 7.5 by 4

Which gives the perimeters as 2*(15 + 2) = 34 or 2*(7.5 + 4) = 23

Therefore, the largest possible rectangle is 34

The correct option is B. 34.
