USPshnik [31]
Depends on how the papers are connected. if they are connected with the 7cm side joining each other, use solution one. if they are connected with the 9cm side joining each other, use solution two.


perimeter of edges of sign= 2 [(9x3)+7]
= 68 inches

left over= 144-68
= 76 inches



OR


perimeter of edges of sign= 2[(7x3)+9]
= 60 inches

left over= 144-60
= 84 inches

Snezhnost [94]

Given:

Henry can type 3500 words in 70 minutes.

Colin can type 1500 in 30 minutes.

Brian can type 2200 words in 40 minutes.

To find:

The person who types at the fastest rate of words per minute.

Solution:

We know that,

\text{Rate of words per minute}=\dfrac{\text{Number of words}}{\text{Number of minutes}}

Using this formula, we get

\text{Henry's rate of words per minute}=\dfrac{3500}{70}=50

\text{Colin's rate of words per minute}=\dfrac{1500}{30}=50

\text{Brian's rate of words per minute}=\dfrac{2200}{40}=55

Since 55>50, therefore Brian's types at the fastest rate of words per minute.

Anit [1.1K]

The hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm

<h3>Common multiple</h3><h3 />
  • Hamster 4oz of food = 6 hours
  • Guinea pigs 12oz of food = 12 hours
  • Land tortoise 24oz of food = 24 hours

Find the lowest common multiple

  • 6 hours = 6, 12, 18, 24
  • 12 hours = 12, 34, 36
  • 24 hours = 24, 48, 72

The lowest common multiple of 6, 12 and 24 is 12

if Frankie starts at 6:00 Am?

6:00 am + 12 hours

= 6:00 pm

Therefore, the hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm
