Joe made a scale drawing of the community pool in his town.
Effectus [21]

Answer:

The length of the pool is 28 meters and the width of the pool is 10.5 meters.

Step-by-step explanation:

In the scale drawing of Joe, the community pool has (length : width) = 8 : 3  

Let the actual length of the pool is 8x meters and the actual width is 3x meters.  

Now, given that the actual pool has a perimeter of 77 meters.  

So, 2(8x + 3x) = 77  

⇒ 22x = 77  

⇒ x = 3.5  

So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)

wea re going to the carnival on friday night . It costs $2 for each ride and $5 for snacks. Lelia has 23 total to spend. Write a
777dan777 [17]

Answer:

In total you can buy 3 snacks and ride 4 rides.

Step-by-step explanation:

$2 per ride

$5 for snacks

The equation here is $2r + $5s = $23

First I found out how many times I could multiply 5. First I though 4 but 2 doesnt go into the remaining 3, so I lowered it down to 15 which is 3.

So s = 3

Now our equation is 2r + 15 = 23

Subtract 23 - 15 = 8

Now divide

r = 8 / 2

r = 4

Which is bigger, one fourth of 16 or one third of 24?
sesenic [268]
One third of 24 because 3 is a whole number smaller than 4 so the answer would be 3/24 not 4/16.
