Original formula:

P/2-5 when p=14

You just need to plug in 14 in place of where the variable p is at. This is called substitution.

14/2-5

By the rules of PEMDAS, we will execute 14/2 first. (7)

7-5

2 is your final answer.

Giovanna used the calculations below to determine the height of a stack of 7 books that are each 2 and StartFraction 5 over 8 En

igor_vitrenko [27]

The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)

<h3>Fraction</h3>

Her calculation:

7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)

7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)

14 + StartFraction 5 over 8 EndFraction: 14 + 5/8

14 and StartFraction 5 over 8 EndFraction: 14 5/8

Her error was multiplying 7 by 2 and adding with 5/8(step 3)

Correct calculation:

7(2 + 5/8)

= 14 + 35/8

= (112+35) /8

= 147/8

= 18 3/8

Rectangular prism container holds about 1320 ml of water. Its length, width and height are consecutive whole number. It's dimens

Black_prince [1.1K]

Answer:

$10cm\times 11 cm\times 12 cm$

Step-by-step explanation:

We are given that

Volume of water=1320 ml=1320 cubic cm

1ml=1 cubic cm

One dimension of rectangular prism=l=10 cm

Length,width and height are consecutive whole number

Breadth of rectangular prism=x+1

Height of rectangular prism=x+2

Volume of rectangular prism=lbh

Using the formula

$1320=10(x+1)(x+2)$

$x^2+x+2x+2=\frac{1320}{10}=132$

$x^2+3x+2-132=0$

$x^2+3x-130=0$

$x^2+13x-10x-130=0$

$x(x+13)-10(x+13)=0$

$(x-10)(x+13)=0$

$x-10=0\implies x=10$

$x+13=0\implies x=-13$

x=-13

It is not possible because length cannot be negative.

Length of rectangular prism=10 cm

Breadth of rectangular prism==10+1=11 cm

Height of rectangular prism==10+2=12 cm

Dimensions of the prism is given by

$10cm\times 11 cm\times 12 cm$
