If 1/4
inch equals 50 miles, find the miles represented by 4 1/2
inches.

Answers

Answer 1
Answer:

Answer:

900

Step-by-step explanation:

Given: 1/4 in. = 50 miles

Find the amount of miles per inch. Multiply 4 to both sides of the equation.

(1/4 in.) x (4) = (50 miles) x (4)

4/4 in. = 200 miles

1 in. = 200 miles

Now, find the amount of miles for 4 1/2 in. Multiply 4 1/2 to both sides.

Note that 4 1/2 = 4.5

(1 in.)(4.5) = (200 miles) x (4.5)

4.5 = 200 x 4.5

4.5 = 900

900 miles is your answer.

2 1/3 + 1 2/3 = 3 3/3

2 1/3 + 1 2/3 = 4
2 + 1 = 3; 1/3 + 2/3 = 1
3 + 1 = 4

3 3/3 = 4
3 = 3; 3/3 = 1
3 + 1 = 4

Now, let's come up with a fraction that is equal to 4.

2 6/3

This answer works because we already have 2 as an integer, and 6/3 is 2.
2 + 2 = 4

Hope this helps!

How would I figure out what L= is if V=168 yd W= 7 yd H= 3 yd?

Answers

We can assume that the shape is a rectangular prism by the given dimensions

Volume of a rectangular prism
Volume = Area of Base × Height of prism
             = Length × Width × Height of prism
Substitute!
168 = L × 7 × 3
168 = L × 21
Divide 21 on either sides to isolate L

(168)/(21) = (L*21)/(21)
21 and 21 cancels out

8 = L
L = 8 yd
