iren2701 [21]

Answer:

Last year the cost was $28.

This year the cost is $36.

$36 - $28 = $8

Percent of increase = amount of increase ÷ original amount

$8/$28 = $0.286

$0.286 · 100 = 28.6%

There has been a 28.6% of change in the cost.

An insect crawls up 5cm every second on a 6cm vertical rod and then falls down 2cm over the next second. How many seconds will i
makkiz [27]

Answer:

3 seconds

Step-by-step explanation:

It's quite simple. First, add 5cm to the progress of the insect, counting it as 1 second. Then subtract 2cm because it falls over the next second, thus taking another second. Then finally, plus 5cm, making it 3 seconds. It's not 4 seconds because at 3 seconds it had already reached the top.

If I didn't clear everything or messed up, please comment.

A shelter has 5 dogs for every 4.cats. How many cats will the shelter have if they have 25 dogs?
olga_2 [115]

Answer:

20 cats

Step-by-step explanation:

A proportion has to be setup to answer this

5/4 = 25/x

x represents the missing number of cats

This fraction represents the relationship amongst dogs and cats

----

To solve cross multiply

5x = 100

(let me down below if you need an explanation on how to cross multiply)

Divide both sides by 5 in order to get the variable by itself

100/5 = 20

x = 20

The shelter has 20 cats
