A floor 10m by 40m is covered by square tiles 20cm. How many tiles are needed to cover the floor?
Lady_Fox [76]

Answer:

10,000

Step-by-step explanation:

We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.

1 m = 100 cm

10 m = 1000 cm

40 m = 4000 cm

area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2

area of tile = s^2 = (20 cm)^2 = 400 cm^2

number of tiles = 4,000,000/400 = 10,000

Answer: 10,000 tiles

ivann1987 [24]

Answer:

Option D: 7.59*10^{2}

Step-by-step explanation:

we know that

The volume of Saturn is about 8.27*10^{14}\ km^{3}

The volume of Earth is about 1.09*10^{12}\ km^{3}

Dividing Saturn's volume by Earth's volume

\frac{8.27*10^{14}}{1.09*10^{12}} =(\frac{8.27}{1.09})*10^{14-12} =7.59*10^{2}

13. t plus the product of three and t​
Sindrei [870]

Answer:

4t

Step-by-step explanation:

Let's form an equation here just to put it visually.

So it would be t+3*t

We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)

Now we can do t+3t which is 4t

If this doesn't make sense, then you can look at it this way

You do 1t+3t and since they're like terms, you can combine them and do 4t.
