How many square inches of paper did Benjamin use to wrap the box

Mathematics
1 answer:
ozzi3 years ago
7 0

Answer:

2,124\ in^{2}

Step-by-step explanation:

we know that

The surface area of a rectangular prism is equal to

SA=2B+Ph

where

B is the area of the base

P is the perimeter of the base

h is the height

In this problem we have

B=18*24=432\ in^{2}

P=2(18+24)=84\ in

h=15\ in

substitute

SA=2(432)+(84)(15)=2,124\ in^{2}

Two cones have the same radii but one has a height four times larger than the other. How many small cones would be needed in ord
hram777 [196]
Since the radius is the same but the height changes, the volume would change by the multiple of the height.
 In this case the volume of the larger cone would be 4 times as large as the smaller cone so you would need 4 small cones

Which do the following equations represent? -4x-5y=-4 and 10x-8y=-1
kicyunya [14]
Parallel have same slope
Perpendicular have opposite reciprocal slopes. Ex. 2/3 is slope of one line so the perpendicular line would have slope of -3/2.

Find slopes of these lines.

-4x-5y=-4
-4x+4 =5y
Divide by 5

Y= -4x/5 +4/5

Second line: 10x-8y=-1

10x+1=8y
Divide by 8

10x/8 +1/8 =y

Y= 5x/4 +1/8

So if you look at slope of line 1= -4/5 and line 2 it’s 5/4 so these both are perpendicular.

Plz gyz ineed the calculation
postnew [5]

Answer:

1/8

Step-by-step explanation:

1st day......1/3

2nd day....1/6

3rd day....3/8

common denominator of 24

1/3 + 1/6 + 3/8 = 8/24 + 4/24 + 9/24 = 21/24 (this is water used)

that means that : (24/24 - 21/24) = 3/24 reduces to 1/8 .....water in the tank
