Answer:

400

Step-by-step explanation:

Enough that you will need a large piggy bank to take money out of.\

There are 4 squares of equal size that will fit the floor of a 20 by 20 foot room.

Therefore you will need 4 * 100 = 400 tiles.

You could do it by noting that the floor has 20 by 20 tiles which is 20^2 which is 400.

William has been contracted to paint a school classroom. The classroom is 20 m long, 15 m wide and 5 m high. There are four wind
valina [46]

Answer:

Step-by-step explanation:

l -> length

b -> width

h -> height

Find the area of four walls and ceiling. then subtract the area of four windows and a door form that area.

Area of four walls + <u>ceiling</u> = 2( lh + bh) +<u>lb</u>

 = 2*(20*5 + 15*5) + 20*15

= 2( 100 + 75) + 300

= 2* 175 + 300

= 350 +300

= 650 sq m

Area of window = 2 *3 = 6 sq.m

Area of four windows = 4*6 = 24 sq.m

Area of door = 2 * 1 =  2 sq.m

Area of four walls excluding 4 windows and door = 650 - 24 - 2 = 624 sq.m

Cost of painting = 624 * 6.50

                          = $ 4056

If Sarah has 50 Nickles and 20 dimes and Bill has 230 pennies and 5 quarters. Who has the more amount of money?
ser-zykov [4K]

Hi,

Your Question states: If Sarah has 50 Nickles and 20 dimes and Bill has 230 pennies and 5 quarters. Who has the more amount of money?

Answer: Sarah

Explanation: Sarah amount is $2.50, because the amount of nickels is 5 cents and if you multiply 5 times 50 you answer becomes $2.50. 20 dimes and every dime is 10 multiples up to $2.00. 230 is $2.30, and 5 quarters each being 25 cents is $1.25 so your answer is Sarah with 50 nickels.

I Hope I Helped!
