30 miles per hour.3,520 feet per minute.who runs faster and by how many miles per hour? There 5,280 feet in one mile

Answers

Answer 1

Answer: First let's convert 30 miles to feet.

30 x 5,280 = 158400

Now let's find how many feet the first person runs per minute.

158400/60 = 2640

The first person runs 2,640 feet per minute, and the second person runs 3,520 feet per minute.
Since the second person runs fast, let's find by how many miles per hour they're faster than the first person.

3520-2640 = 880
How many miles is 880 feet?
5280/880 = 0.17

The second person runs faster by 0.17 miles per hour.

Hope this helps! :)

Answer 2

Answer: Hello!

CORRECTION: "A white-tailed deer can sprint at speeds up to 30 miles per hour. American bison can run at speeds up to 3,520 feet per minute. Which animal is faster and by how many miles per hour? There are 5,280 feet in one mile. "

OPTIONS:

B: A bison is 10 miles per hour faster than a deer.

C: A deer is 0.66 miles per hour faster than a bison.

D: A bison is 0.66 miles per hour faster than a deer.

This is what you meant right!? ^^^

I've done this Question before, so i'll Help You Then!

We 1st off, have to convert the ft/min speed into miles/hour:

3520 feet ... 1 mile ..... 60 minutes ... 3520 x 60 miles
-------------- x ------------- x ---------------- = ---------------
1 minute ... 5280 feet .... 1 hour .......... 5280 hours

= (3520 * 60) / 5280
= 40 miles/hour

The Correct Answer Is:
B. The bison is 10 miles per hour faster than a deer.

Hope this Helps! Have A Wonderful Day! :)

After 25% of a bill is paid $80 still remains to be paid. how much was the bill?

Answers

the original bill was valued at 106.67 $

if 25% was paid, and 80 dollars are left, this means that 80 dollars is 75% of the bill. 25% is a quater, and 75% is three quarters.

here, we can divide 80 into three parts ->

80 ÷ 3 ≈ 26.67
that means a quater of the bill is 26.67 $

if 80$ were left to be paid, just add the 26.67$ from the first quater ->

80 + 26.67 = 106.67 $

Which statement about this linear system must be true?

a) x must equal 6

b) y must equal 6

c) there is no solution to this system

d) there are infinitely many solutions to this system

Answers

There are infinitely many solutions because the first two equations are actually the same just arranged differently so there's not enough information to know what x or y are in other words they could be anything.

Answer:

-1/2 or -1.5

Step-by-step explanation:

The y intercept is where the line or function crosses the y axis or the up and down axis or vertical axis. As you can see, f(g) is the blue line, and it crosses the y axis at about -1.5 or 1/2. HOPE THIS HELPS!
