Answer: 16

Step-by-step explanation: Here's a little tip for you. Any number can be converted to a fraction if you use 1 as the denominator:

64/1

So now that we've converted 64 into a fraction, to work out the answer, we put the fraction 1/4 side by side with our new fraction, 64/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

1x64/4x1 = 64/4

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers:

The GCF of 64 and 4 is 4.

We can now divide both the new numerator and the denominator by 4 to simplify this fraction down to its lowest terms:

64/4 = 16

4/4 = 1

When we put that together, we can see that our complete answer is:

16/1

The complete and simplified answer to the question what is 1/4 of 64 is:

Hopefully, this tutorial has helped you to understand how to find the fraction of any whole number. You can now go give it a go with more numbers to practice your newfound fraction skills.

A neighborhood development that is 4 acres is to be divided into 2/3 acre lots. How many lots can be created?

mihalych1998 [28]

6 lots can be created

Solution:

Given that neighborhood development that is 4 acres is to be divided into $\frac{2}{3}$ acre lots

To find: number of lots created

From given information,

Total acres = 4

one lot = $\frac{2}{3} \text{ acres }$

So number of lots created can be found by dividing the total acres by acre of 1 lot

Thus the formula is:

$\text{ Number of lots } = \frac{\text{ total acres }}{\text{ acre of 1 lot }}$

Substituting the values we get,

$\text{Number of lots } = \frac{4}{\frac{2}{3}} = 4 \times \frac{3}{2} = 6$

Thus 6 lots can be created

a sporting goods store offers a 40% discount on all golf clubs. Rocco spent 20% of the money in his savings account on a golf pu

Inessa05 [86]

$189

If the discounted price is $210, and his friend gets a 10% discount on that price, you can divide 210/10 and get 21.

Rocco's friend gets a $21 discount on the $210 irons, so therefore he will be paying $189

Based on concerns raised by his preliminary research, the biologist decides to collect and examine 150 frogs.

Delicious77 [7]

Answer:

Answered and explained below

Step-by-step explanation:

A) We are told that frequency of the trait is still 1 in 8. Thus, population proportion; p = 1/8 = 0.125

Sample size; n = 150

Formula for mean is;

μ = np

μ = 150 × 0.125

μ = 18.75

Formula for standard deviation is;

σ = √(np(1 - p))

σ = √(150 × 0.125(1 - 0.125))

σ = √16.40625

σ = 4.05

B) usually, when np ≥ 10 , we make use of normal distribution.

I'm this case, it is 18.75 which is greater than 10.

Thus,we can use a normal model to approximate the distribution.

C) we are told that he found the trait in 22 of the frogs.

Thus;

Proportion is now; 22/150 = 0.1467

This is a higher probability that the initial one of 0.125 and we can say that the trait has become more common.

A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 9 inches, a width of 3 inches, and a h

Answer:

$Area = 138in^2$

Step-by-step explanation:

Given

$L = 9; W =3; H =3\frac{1}{2}$

Required

The surface area

This is calculated as:

$Area = 2(LW + LH + WH)$

So:

$Area = 2(9*3 + 9*3\frac{1}{2} + 3*3\frac{1}{2})$

$Area = 2(27 + 31\frac{1}{2} + 10\frac{1}{2})$

$Area = 2*69$

$Area = 138in^2$
