mr mohr wants to build a rectangular patio the patio will measure 13.5 feet by 43 feet what is the area of the patio if he uses tiles that are 12 inches square to cover the area of the patio how many tiles will he need I need help

Answers

Answer 1

Answer: Area of a rectangle is (length) x (width) . (You're supposed to know this.)

Area of Mr. Mohr's patio = (13.5) x (43) = 580.5 square feet.

12 inches = 1 foot

Area of each tile = (1 foot) x (1 foot) = 1 square foot.

So Mr. Mohr needs at least 581 tiles to cover the whole patio.

That's if he's really good at cutting tiles into smaller pieces, because
he can't use all whole tiles to cover the 13.5 feet dimension.

In any case, the patio is 580.5 square feet, and each tile is 1 square foot,
so he needs to buy a minimum of 581 tiles.

Answer 2

Answer: 13.5*43=580.5
580.5/1=580.5
The area of the patio is 580.5² ft and he will need to purchase 581 tiles.

A drawer has some red ,green and blue marbles.there are 33 marbles . there are 4 times as many red marbles as green marbles.there are half as many blue marbles as green marbles.how many blue marbles are in the drawer?

Answers

Answer:

The number of blue marbles be 3.

Step-by-step explanation:

As given

A drawer has some red ,green and blue marbles.

There are 33 marbles .

there are 4 times as many red marbles as green marbles.

Let us assume that the number of green marbles be g .

Than Red marbles = 4g

There are half as many blue marbles as green marbles.

Than

$Number\ of\ blue\ marbles =\frac {Number\ of\ green\ marbles}{2}$

$Number\ of\ blue\ marbles =(g)/(2)$

Than the equation becomes

$g + 4g + (g)/(2) = 33$

Than simplify the above

$2g + 8g + g = 33* 2$

$11g = 66$

$g= (66)/(11)$

g = 6

$Number\ of\ blue\ marbles =(6)/(2)$

Number of blue marbles = 3

Therefore the number of blue marbles be 3 .

$g-green\ marbles\nr-red\ marbles\nb-blue\ marbles\ng+r+b=33\n\n4g-red\ marbles\n(1)/(2)g-blue\ marbles\n\ng+4g+(1)/(2)g=33\n\n5(1)/(2)g=33\n\n(11)/(2)g=33\ \ \ \ /\cdot(2)/(11)\n\ng=3\n\nAnswer:b=(1)/(2)g\to b=(1)/(2)\cdot6=3$

Kim and Sam went to Mexico Restaurant for lunch. The total bill was $21.58. They decide to leave an 18% tip. How much will the tip be? How much total will they spend on lunch?

Answers

Answer:

$3.88

Step-by-step explanation:

You want to leave a 18% tip on a meal that cost $21.58.

First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.

Second, you need to find out what 18% of your $21.58 meal cost is.This is always done by multiplying 0.18 by $21.58, or 0.18 x $21.58=$3.88.

So, the amount of tip you are going to leave is $3.88.

Ruby ate 1/3 of a pizza, and Angie ate 1/5 of the pizza. How much of the pizza did they eat in all?

Answers

Find common denominators. Multiply 5 to numerator and denominator of 1/3, and 3 to the numerator and denominator of 1/5

(1/3)(5/5) = 5/15

(1/5)(3/3) = 3/15

Add

5/15 + 3/15 = 8/15

Ruby and Angie ate 8/15 of the pizza.

hope this helps
