Meg is packing a shipping conditier.
allochka39001 [22]

Answer:

Boxes= 198

Step-by-step explanation:

<em>This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.</em>

<em></em>

<u>We have the following given parameters.</u>

<u>Shipping Container</u>

Dimension: 2ft\ by\ 3ft\ by\ 33ft

<u>The box</u>

Dimension: 1ft\ by\ 1ft\ by\ 1ft

First, we calculate the volume of the shipping container.

V_A  = 2ft * 3ft * 33ft

V_A  = 198ft^3

Next, we calculate the volume of the box.

V_B  = 1ft * 1ft * 1ft

V_B = 1ft^3

The number of box is then calculated as:

Boxes= \frac{V_A}{V_B}

Boxes= \frac{198ft^3}{1ft^3}

Boxes= \frac{198}{1}

Boxes= 198

Hence:

<em>198 boxes will occupy the empty space</em>

Haley is printing admission tickets for her school dance. So far, she has printed 112 tickets. She knows that she needs to print
crimeas [40]

Answer:

Haley needs to print 65% of the tickets.

Step-by-step explanation:

Given that:

Tickets printed by Haley = 112

Tickets needed to print = 320

Tickets left to print = 320-112 = 208

Percent of tickets left to print = \frac{Tickets\ left\ to\ print}{Total\ tickets}*100

Percent of tickets left to print = \frac{208}{320}*100

Percent of tickets left to print = 0.65*100

Percent of tickets left to print = 65%

Hence,

Haley needs to print 65% of the tickets.
