We are given that the surface area A is:

A = 5.2 ft^2

To convert this into in^2, we know that there are 12 inches in 1 feet, so 12 in = 1 ft:

A = 5.2 ft^2 * (12 in / 1 ft)^2

yulyashka [42]

Their error is that they divided 12 by 30, instead of 30 by 12 in order to get the price per pair

the correct unit price is $2.50 per pair

Which choices are equivalent to the fraction below check all the apply ""24" over 30

user100 [1]

Answer:

c) The reduced form of the given fraction $\frac{24}{30} = \frac{4}{5}$

Step-by-step explanation:

Here, the given expression is "24 over 30".

The given expression is is equivalent to $\frac{24}{30}$

Now by Prime Factorization:

24 = 2 x 2 x 2 x 3

30 = 2 x 3 x 5

⇒ The common factors in 24 and 30 is 2 x 3 = 6

So, $\frac{24}{30} = \frac{2 \times 2 \times 2 \times 2 \times 3}{2 \times 3 \times 5} = \frac{6 \times 4}{6 \times 5} = \frac{4}{5}$

Hence the reduced form of the given fraction $\frac{24}{30} = \frac{4}{5}$

Which is equivalent

arlik [135]

Answer:

D 8√(10) ^3x

Step-by-step explanation:

We have

sqrt(10) ^ (3/4x)

We can rewrite the sqrt as ^1/2

10 ^ (1/2) ^ (3/4x)

We know that a^b^c = a^(b*c)

10 ^(1/2 *3/4x)

10 ^(3/8 x)

The numerator is the power

The denominator is the root

8√(10) ^3x
