Please tell me what is 5mi in feet

Answers

To find out what 5 miles in feet would be, you simply have to multiply the amount of feet per mile by 5.

5280 * 5 = 26400

There are 26,400 feet in 5 miles.
Hope that helped! =)
one mile will be converted into 5280 feet so you multiply 5280*5= 26400

A truck can be rented from Company A for ​$80 a day plus ​$0.30 per mile. Company B charges ​$20 a day plus ​$0.50 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same

Answers

Write equations for both companies:

Company A = 80 + 0.30x

Company B = 20 + 0.50x

X = number of miles.

Set the equations to equal and solve for x:


80 + 0.30x = 20 + 0.50x

Subtract 0.30x from both sides:

80 = 20 + 0.20x

Subtract 20 from both sides:

60 = 0.20x

Divide both sides by 0.20:

x = 60 / 0.20

x = 300


The answer is 300 miles.

Identify the hypothesis of the following conditional statement: If an angle measures 120°, then it's an obtuse angle. Question 12 options: A) An angle doesn't measure 120°. B) It isn't an obtuse angle. C) It's an obtuse angle. D) An angle measures 120°.

Answers

Answer: Option D.

Step-by-step explanation:

The "skeleton" of a logic statement is usually:

If "something true" then "this is also true"

Where the correct way to write this is:

"if hypothesis" then "conclusion".

Or

"Conclusion" only if "hypothesis"

There are other ways to write a logical statement, but this gives a general idea.

The hypothesis is the part of a logical statement that gives the premise on which the conclusion is based.

Now, in our statement we have:

If an angle measures 120°, then it's an obtuse angle.

Here the premise, the thing that needs to be true "first" in order to go to the conclusion, is "an angle measures 120°"

Then the correct option is D.

Answer:

D
