a new gym is being built at greenfield middle school. The length of the Gym is 12 inches on the builders blueprint. Find the actual length of the gym if the scale is 3/4 in = 5ft

Answers

Using scale conversion in mathematics, we set up a proportion based on the blueprint scale of 3/4 in equals 5 ft. Solving this proportion, we find the actual length of the gym is 80 feet.

In mathematics, this problem is about scale conversion.

The blueprint scale in this case is 3/4 in equals 5 ft.

To find out the actual length of the gym, we need to set up a proportion and solve for the missing value.

We know that 3/4 inches represents 5 feet on the actual gym.

According to the blueprint, the length of the gym is 12 inches.

First, let's set up the proportion: 3/4 in: 5 ft = 12 in: x ft.

Now we can cross multiply and solve for 'x'. (3/4) * x = 12 * 5, which simplifies to (3x/4) = 60.

Multiply both sides by 4 to isolate 'x': 3x = 240.

Finally, divide both sides by 3, we get x = 80.

Therefore, the actual length of the gym is 80 feet.

Jac thinks of a number. 25% of his number is 35. What is 1/10 of Jac's number?​

Answers

Answer:

Step-by-step explanation:

Let Jack’s number be x.

25% of x = 35

(25/100) . x = 35

x = 35 . 4 = 140

So Jack’s number is 140. 1/10 of 140 will be (1/10). 140 = 14

Answer: 14

What is the difference in elevation between High Point (673 feet above sea level) and Low point (80 feet below sea level)?

Answers

Answer:

The difference in elevation between High Point and Low Point is of 753 feet.

Step-by-step explanation:

Since High Point is located at 673 feet above sea level (+673) and Low Point is located at 80 feet below sea level (-80), in order to know the difference in elevation between both points we have to do the following calculation:

673 - (-80) = Difference

673 + 80 = Difference

753 = Difference

The difference in elevation between High Point and Low Point is of 753 feet.

Difference is subtraction so 673-80 = 593. 593 is your answer. ;) Hope I helped.

Ken drew a pair of intersecting rays and marked the angle between them.Which of these statements best compares the pair of intersecting rays with the angle?
-The rays and the angle have two endpoints each.
-The rays and the angle have their lines extending in opposite directions.
-The rays have a number of points lying on them and the angle has only one point lying on it.
-The rays extend infinitely and the angle is made by the rays which have a common endpoint.
...?

Answers

The best and most correct answer among the choices provided by your question is the fourth choice.

The rays extend infinitely and the angle is made by the rays which have a common endpoint.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:

-The rays extend infinitely and the angle is made by the rays which have a common endpoint.

Step-by-step explanation:

A ray starts from one point and extends in one direction forever.

An angle is the space between two intersecting lines at or close to the point where they meet. In this case two rays intersect each other at one point
