How many square tiles of side 10cm each will be needed to tile a floor which is 300cm long and 150cm wide?
S_A_V [24]

Step 1

Find the area of one tile

we know that

the area of a square is

A=b^{2}

where b is the length side of the square

In this problem

b=10\ cm

Substitute

A=10^{2}=100\ cm^{2}

Step 2

Find the area of the floor

The area of a rectangle is equal to

A=LW

where

L is the length of the rectangle

h is the width of the rectangle

In this problem

L=300\ cm

W=150\ cm

Substitute

A=300*150=45,000\ cm^{2}

Step 3

Find the number of tiles needed

by proportion

\frac{1}{100} \frac{tile}{\ cm^{2}} =\frac{x}{45,000} \frac{tile}{\ cm^{2}} \\ \\x=45,000/100 \\ \\x=450 \ tiles

therefore

<u>the answer is</u>

450 \ tiles

What is the unit rate to this equation? 346 miles on 22 gallons
kondaur [170]
Calculating the unit rate is not that problematic if you can understand the requirement. Using the details given the answer to the question can be easily determined.
Number of miles that it goes in 22 gallons = 346
Then
Number of miles that it goes in 1 gallon = (346/22) miles
                                                                = 15.73 miles
So
The unit rate to this equation is 15.73 miles per gallon. I hope the procedure is clear enough for you to understand.You can always use this procedure for solving similar problems in future.

last month, dory biked 11 times as many miles as karly. together they biked a total of 156 miles. how many miles did dory bike l
Anni [7]

Hi there

Let x be the number of miles Karly biked
Dory biked 11 times as many miles as Karly, therefor, Dory = 11x
The total number of miles back by both is 156
The equation will be:
11x + x = 156
Before we can get the number of miles Dory biked, we must first get the number of miles
Karly biked represented by x.
Get the x
12x = 156
12x/12 = 156/12
<span>x = 13 </span>
Karly = x = 13 miles biked
Dory = 11x = 11(13) = 143 miles biked
to check:
11x + x = 156
11(13) + 13 = 156
143 + 13 = 156
<span>156 = 156
  i hope it helps have a nice day:)

Which is greater 3 miles or 5,000 yards? How much greater? Explain.
Mariulka [41]

Answer:

3 miles is greater than 5000 yards by 280 yards.

Step-by-step explanation:

There are 1760 yards in a mile.

3*1760=5280

That means there are 5280 yards in 3 miles.

5280 > 5000

This means that:

3 miles > 5000 yards

Now, we can find the difference.

5280-5000=280

3 miles is greater than 5000 yards by 280 yards.
