The percent increase is 80%

Step-by-step explanation:

Percent increase is given by:

Percent\ Increase=\frac{Increase}{Previous\ value}*100\\While\\Increase= New\ value - Old\ value\\

Here

New value = 36

Old Value = 20

Increase = 36-20 = 16

So,

Percent\ increase=\frac{16}{20}*100\\=0.8*100\\=80\%

Hence,

The percent increase is 80%

Determine if y varies directly with x. Give the constant of variation, when appropriate. (picture below)
maxonik [38]

Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.

<h3>Variation</h3>

y = k × x

where,

k = constant of proportionality

y = -40

x = -5

y = k × x

-40 = k × -5

-40 = -5k

k = -40/-5

k = 8

when,

y = 8 and x = 2.5

y = k × x

8 = k × 2.5

8 = 2.5k

k = 8/2.5

k = 3.2

when,

y = 5 and x = 4

y = k × x

5 = k × 4

5 = 4k

k = 5/4

k = 1.25

(1) 16 liters of kerosene is needed for 12 stoves 14
Nastasia [14]

9514 1404 393

Answer:

  12 liters

Step-by-step explanation:

The kerosene usage is assumed to be jointly proportional to the number of stoves and the number of hours. That is ...

  v = k·s·h . . . . . for s stoves running h hours

Then the value of k is ...

  k = v/(sh) = (16 L)/(12·14) = 2/21 . . . . liters per stove-hour

Then the volume of kerosene required for 7 stoves and 18 hours is ...

  v = (2/21)·s·h

  v = (2/21)(7)(18) = 12 . . . liters

You roll a standard number cube. Find P(number is not 2).
Morgarella [4.7K]
A standard number cube has 6 sides, and so the numbers are:

1,2,3,4,5,6

P, is any of those numbers that <em>are not 2</em>.

2 is one of the numbers in 6, and so it is 1/6 of the die.

6/6 - 1/6 = 5/6

C) 5/6 is your chance of getting a number that is not 2


hope this helps
