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

Travis wants to buy some CDs over the Internet. Each CD costs $8.01 and has a shipping cost of $9.95 per order. If Travis wants to spend no more than $50 for his CDs, which inequality shows the maximum number of CDs, p, that he can buy?


9.95p − 8.01p ≤ 50, so p ≤ 2

9.95p + 8.01p ≤ 50, so p ≤ 4

9.95 + 8.01p ≤ 50, so p ≤ 5

9.95 − 8.01p ≤ 50, so p ≤ 6

Answers

Answer:

9.95 + 8.01p ≤ 50, so p ≤ 5

Step-by-step explanation:

So to set up the equation you must first add 9.95+ because every order has a shipping fee of 9.95

Then you put in 8.01 is less than or equal to 50 because p representing a number of players is being multiplied by the unit cost 8.01. Trace is also wants the total to be under 50 dollars

Finally p is less than or equal to 5 because if you put the value 5 in for p in the equation, the equation is true.

The whole equation is 9.95 + 8.01p ≤ 50, so p ≤ 5

9.95 + 8.01p ≤ 50, so p ≤ 5

Cindy has a poster in the shape of a parallelogram.

What is the area of this parallelogram?

Answers

Answer:

3.60

Step-by-step explanation:

took the test

Answer:

Area of the parallelogram is 3.69 ft²

Step-by-step Explanation:

We have,

A parallelogram in shape of a poster.And we need to find the area of parallelogram.

For solving,

The parallelogram is divided in 3 parts. 2 triangles and one rectangle.We will find all of there areas separately and then will add it up to have the final area of parallelogram.

★Area of triangles:

= ½ × base × height

= ½ × 0.5 × 1.5

= 0.5 × 0.75

= 0.375 ft²

Since there are to triangles of same size,

= 2 × 0.375

= 0.75 ft²

★Area of rectangle:

= Length × breadth

= 1.9 × 1.5

= 2.85 ft²

★Final area of parallelogram:

= Area of both triangles + area of rectangle

= 0.75 + 2.85

= 3.60 ft²

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)

Suppose a cheetah could travel 1.5 hours a top speed covering 111.9 miles how far could the cheetah travel in 1 hour

Answers

1 hour = 74.6
u get that by doing :
37.3(2) which equals 74.6

The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

A cheetah could travel for 1.5 hours at a top speed covering 111.9 miles.

The ratio of the number of miles to time = 111.9/1.5

With the same ratio, the number of miles x in 1 hour will be as,

x/1 = 111.9/1.5

x = 74.6 miles.

Hence "The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles:".

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)
