The whole pie is 1, because 1 is 100%. Tom ate 2/3 of 1 and Sam ate 1/4 of the pie.
So, here's how to determine how much is left:
1 - (2/3 + 1/4) = 1 - (8/12 + 3/12) = 1 - 11/12 = 12/12 - 11/12 = 1/12

The correct answer is that 1/2 of the pie is left.

The surface area of this rectangular prism is 1,414 square meters. What is the volume?

Mice21 [21]

Answer:

2940

Step-by-step explanation:

Surface Area of a rectangular prism is 2(LW)+2(HW)+2(LH)

We have that the surface area is 1414 where L=c , H=20, W=7

Let's plug all of this in to solve for c:

2(LW)+2(HW)+2(LH)=1414

2(c*7)+2(20*7)+2(c*20)=1414

14c+280+40c=1414

54c+280=1414

54c=1414-280

54c=1134

c=1134/54

c=21

Now the volume of a rectangular prism is V=L*W*H

So plug in our values L=21, H=20, W=7

V=21*20*7=2940

Answer:

1 ÷ 6

Step-by-step explanation:

1/6 is a division expression. It means "one divided by six."

The slash (/) can be replaced by the "divided by" symbol (÷), if you like.

1/6 = 1 ÷ 6 . . . . means "one divided by six"

Do 18/24 and 10/15 have the same value? Explain your answer in complete sentences.

LenaWriter [7]

Answer:

Step-by-step explanation:

We can either cross multiply or turn into decimal form to see if they have the same value.

I will be showing both.

Cross Multiply: Decimal Form:

$\frac{18}{24} \;[\;\;] \frac{10}{15}$ $\mathrm{To\;turn\;fraction\;into\;decimal\;just}$

$18\times15=270$ $\mathrm{Divide\;numerator \;by \;denominator\;}$

$24\times10=240$ $\mathrm{18\div24=0.75}$

$\frac{18}{24} \;[ > ] \frac{10}{15}$ $\mathrm{10\div15=0.66666666666}$

$\mathrm{As\;a\;result\;we\;can}$ $0.75 > 0.66666666666$

$\mathrm{conclude\;that\;\frac{18}{24} \;is\;greater\;than\;\frac{10}{15}}$ $\frac{18}{24} \;[ > ] \frac{10}{15}$

We can conclude that 18/24 and 10/15 are not the same.

Trevor tutors French for $15 and hour and scoops ice cream for $10 an hour. He is going to work 15 hours this week. How many hou

VladimirAG [237]

Total number of hours = 15
Let the hours spent tutoring french be x.
Therefore hours spent on scooping ice cream = (15 - x)
Amount: Tutoring french is $15 an hour, total for x hours = 15x
For scooping ice cream it is $10 an hour 10*(15 - x) = 150 - 10x
To make more than $180
15x + (150 - 10x) > 180
15x + 150 - 10x > 180
15x - 10x > 180 - 150
5x > 30
x > 30/5
