Dimension of one of the floors of one room that David wants to install tiles is 18feet long by 12 feet wide
Then
Area of the above room = 18 * 12 square feet
= 216 square feet
Dimension of the floor of the other room that David wants to install tiles is 24 feet long and 16 feet wide
Then
Area of the other room = 24 * 16 square feet
= 384 square feet
Then
The total square feet of the
rooms that David wants to install tiles = 216 + 384
= 600 square feet
Cost of the tile that covers 1 square feet = $5
Cost of the 4 tiles that cover 4 square feet = $17
Then
Area that can be covered with 4 square feet of tiles = 600/4 square feet
= 150 square feet
Minimum cost of covering
the two rooms that David wants to install tiles = 150 * 17 dollars
= 2550 dollars
So the minimum cost of installing the tiles on the two floors of David's two rooms is $2550. I hope the procedure is simple enough for you to understand.
Answer:
The answer is 16%
Step-by-step explanation:
use the percent error formula.
in this problem,
e= 75
t=90
substitute and solve.
16%
we are dealing with percents so rounding to nearest whole number will suffice.
hope this helps!
Answer:
angelfish can swim faster by 12.5 feet per second
Step-by-step explanation:
60 feet in 6 seconds is 10 feet per second
45 feet in 2 seconds is 22.5 feet per second
A rainbow fish can swim 10 feet per second but an angelfish can swim 22.5 feet per second which means, the angelfish can swim faster by 12.5 feet per second.
We don’t know which one is the hypotenuse. So if we were to plug it into the Pythagorean theorem, we wouldn’t know where to put it. Two possible answers:
8 squared (copy pasting the symbol here is an inconvenience) + b squared = 10 squared which is 6m after solving.
Or you could say 8 squared + 10 squared = c squared. Solving for C would get us 12.8m as our second possibility.
