It’s 20 I believe. All together it should be 160 so you add 118 and 22 to get 140. Then subtract that from 160 and you get 20.

On Friday there were 8 snowboarders for every 3 skiers at Slovak ski resort. On Saturday the ratio of the number of snowboarders

atroni [7]

Answer:

There are 46 more skiers than snowboarder

Step-by-step explanation:

Given

Ratio of Snowboarders to Skiers

On Friday:

$Ratio = 8 : 3$

On Saturday:

$Ratio = 4 : 7$

Population = 168

Required

Determine the difference in the number of skiers and snowboarders on Saturday

On Saturday, we have

$Ratio = 4 : 7$

Calculate Total

$Total = 4 + 7$

$Total = 11$

Calculate the number of skiers

$Skiers = \frac{7}{11} * 168$

$Skiers = \frac{1176}{11}$

$Skiers = 107$ (Approximated)

Calculate the number of snowboarders

$Snowboarders = \frac{4}{11} * 168$

$Snowboarders = \frac{672}{11}$

$Snowboarders = 61$ (Approximated)

Calculate the difference

$Difference = 107 - 61$

$Difference = 46$

<em>Hence, there are 46 more skiers than snowboarder</em>

What is the slope of a line whose graph is parallel to the graph of -3x+y=2?

liq [111]

Answer:

Step-by-step explanation:

if the lines are parallel they have the same gradient.

rearrange the equation to make y the subject and then use the m value as gradient.

-3x=2-y

-3x-2=-y

y=-(-3x-2)

y=3x+2

therefore m=3

slope is 3
