What is the height of the 8 stacks

Okay so to find volume of an object, it's "length×height×width/breadth".

Volume= length×height×width

V = l × h × w

In this case, you're sort of going backwards, trying to find the height.

So input the info you have:

10 (2)/(3) = 1 (1)/(3) × 4 × height

Multiply...

10 (2)/(3) = 5 (1)/(3) × h

Move them by using the simple algebra rules

10 (2)/(3) ÷ 5 (1)/(3) = h

2 cubic feet = height

Barrett and Penelope have some quarters for the vending machine.
lutik1710 [3]

Answer:

if we take the number of quarters Barrett have to be x we know Penelope has twice that ie 2x. so in total they have 2x+x = 60, 3x = 60; so x= 60/3 = 20.

Barrett has 20 quarters.

Write a statement that why isn't 6.5 / 0.5 = 3.25
maxonik [38]

Step-by-step explanation:

6.5 / 0.5

= 6.5 / (1/2)

= 6.5 * (2/1)

= 13.

Since 13 is unequal to 3.25,

we conclude 6.5 / 0.5 = 3.25 is false.

the length of a rectangle is 9 centimeters more than the width. the area is 112 square centimeters. find the length and width of
NeX [460]
Here,
let width(b)be x then,
length (l)=9cm+x
area =112 sq cm
now,
area of rectangle=l*b
or, 112=(9+x)x
or, 112=9x+x^2
or, 0=x^2+9x-112
or, 0=x^2+(16-7)x-112
or, 0=x^2+16x-7x-112
or, 0=x(x+16)-7(x+16)
or, 0=(x-7)(x+16)
either,
0=x-7
or,7=x
x=7cm
Or,
0=x+16
or, -16=x
x= -16[impossible,as distance is never negative] so,
x=7cm
therefore,length = 7cm + 9 cm = 16cm and width = 7cm.
