Answer: Height of the block of southern pine is 7 cm.

Step-by-step explanation:

Since we have given that

Mass = 54.6 g

Density = 0.65 g/cm³

First we calculate the "Volume ":

Density=\dfrac{Mass}{volume}\\\\0.65=\dfrac{54.6}{Volume}\\\\\dfrac{54.6}{0.65}=Volume\\\\Volume=84\ cm^3

Length of rectangular prism = 4 cm

Width of rectangular prism = 3 cm

Height of rectangular prism be 'h'.

So, Volume of rectangular prism = Length×Width×Height

84=4\times 3\times h\\\\84=12\times h\\\\\dfrac{84}{12}=h\\\\7=h

Hence, height of the block of southern pine is 7 cm.

David brought a variety pack of delicious donuts for his daughters Amy & Anna. Amy ate 2/3 of the pack and Anna devoured 1/4
Naya [18.7K]

Answer:

12

Step-by-step explanation:

Let the total number of donuts in the pack be x.

Amy = 2/3x

Anna = 1/4x

David = 1

x - 2/3x - 1/4x = 1

Find common denominators for 2/3 and 1/4

The common denominator is 12

2/3 * 4/4 = 8/12

1/4 * 3/3 = 3/12

x - 8/12x - 3/12x = 1

x - 11/12x = 1

1/12x = 1

x = 12

You can always check

Amy = 8

Anna = 3

So David must equal to 1

Hope this helps :)

Have an awesome day!
