Answer: 2000/25 = 80 tiles
Step-by-step explanation:
Date: s=20
equation of surface area of a cube prism: surface area = 6s*2
the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2
subtitute values: surface area = 5(20)*2
= 5(400)
surface area = 2000
area of 2 tile is 5*2 = 25 square inches
2000/25 = 80 tiles
Answer:
1 mile
Step-by-step explanation:
We can write a ratio to solve
We know 1 hour is 60 minutes
1/6 mile x miles
------------ = ---------------
10 minutes 60 minutes
Using cross products
1/6 miles * 60 minutes = 10 minutes * x
10 = 10x
Divide by 10
1 = x
1 mile
Edit: Bottom left is correct.
Answer:
unit rate is 2
Step-by-step explanation:
Notice that if we multiply both '1' and '3' in 1/3 by 2, we get:
4/6 : 2/6,
which reduces to 4/2, or 2, which is the desired unit rate.
Answer:
14 + 5x = 39
Step-by-step explanation:
first I had to remember the keywords that gave me a hint of what I have to write. I figured out that more is plus ( + ) , times is multiplication ( x ) , and is is the equal sign ( = ).
