Miles bought a new pair of baseball cleats for $64.95. The sales tax is 6.5%. What is the total cost that Miles will pay?

Answers

Answer: $69.17175

Step-by-step explanation:

The cleats are $64.95. Tax is a percentage taken off certain goods so

6.5% of $64.95 which can be also restructured as 6.5/100 times $64.95 which is $4.22175. Tax is added onto the final cost so he shall pay $64.95 plus $4.22175. (I think)

If line segment AB is 400%, what is the length of a line segment that is 100%?
_____ inch(es)
(Type a whole number or a decimal) ​

Answers

4 divided by 4, equals 1 so that means that 100% out of 400% of the line is equal to 1 inch

If line segment AB is 400%, 1 in is the length of a line segment that is 100%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

from the given diagram, we get,

the line AB = 4 in.

and,  line segment AB is 400%,

now, we have to find the length of a line segment that is 100%.

so, we get,

4 in = 400%

so, 100% = 4/ 400 * 100

               = 1 in.

Hence, If line segment AB is 400%, 1 in is the length of a line segment that is 100%.

A puddle originally contained 2.5 gallons of water. After a hot day, only 1 gallon of water remains.

What is the percent decrease?

Enter your answer in the box.

%

Answers

Answer:

60%

Step-by-step explanation:

There is a 60% decrease because 60% of 2.5 = 1.5

So, 2.5 - 1.5 = 1.

Or

1.5/2.5 = 0.60 (which is 60% as a percentage)

what is 7/12 x 3 as a fraction in simplest form

Answers

Answer:

7/4

Step-by-step explanation:

use cross multiplication and you are going to end up dividing 12 by 3 to get four as your denominator

The solution to the product of the fractions is 7/4

How to evaluate the product of the fractions

From the question, we have the following parameters that can be used in our computation:

7/12 * 3

Express 3 as 3/1

So, we have

7/12 * 3 = 7/12 * 3/1

Evaluate the products of 7 and 3

So, we have

7/12 * 3 = 21/12

Divide 21 and 12 by 3

7/12 * 3 = 7/4

Hence, the solution is 7/4

Answer:

0.6

Step-by-step explanation:

We know that there are 5 counters in total. 3 white and 2 black.

So we know that 3 out of 5 are white and 2 out of 5 are black.

Therefore the chance to get white is 3/5. And for black: 2/5.

We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)

And 2/5 = 0.4 (You can make it 4/10 to make it easier.)
