The number of hours she volunteers each week is 19.834 hours and this can be determined by using the unitary method.
Given :
Emma volunteered at an animal shelter for a total of 119 hours over 6 weeks.
The following steps can be used in order to determine the number of hours she volunteered each week:
Step 1 - The unitary method can be used in order to determine the number of hours she volunteered each week.
Step 2 - According to the given data, Emma volunteered at an animal shelter for a total of 119 hours over 6 weeks.
Step 3 - If Emma volunteers at an animal shelter for a total of 119 hours over 6 weeks then in 1 week she volunteers:
Step 4 - Simplify the above expression.
= 19.834 hours
So, the number of hours she volunteers each week is 19.834 hours.

Answer:
x = -1 and x = 4
Step-by-step explanation:
Firstly solve the quadratic expression of
2x^2-6x-8 = 0....it gives you the two brackets of.....(2x-8)(x+1)=0
then...you equate the two brackets to 0.separately
2x-8 = 0....which gives you...x = 4...as the first solution..then..;
x+1 = 0....which gives you...x = -1...as the second solution
To win a lollipop players have to score exactly 7.
Each lollipop costs the school 30p.
How much should the school expect to raise for charity
if 120 people play the game?
Answer:
The answer is "1500p".
Step-by-step explanation:
The given probability is = 7. so, it is
It implies, that only if people enjoy the sport, its school will gather
But, its side will survive = 30 people, as well as the school would have to invest
for lollipops So, the school will collect =
Answer:
£15
Step-by-step explanation:
First lets find out how much the school earns when 120 play the game.
20p=£0.20 pounds
120 x 0.2= £24 that the school earns
Now to find how much the school needs to pay.
There are 3 out of 12 spaces on the possibility space that are 7's so 3/12 win which simplifies to 1/4.
1/4 of 120= 30 people who win the game
30p=£0.30 pounds
30 x 0.3= £9
What the school earns for people playing the game - money spent on lollipops= money raised for charity
£24-£9=£15
So the answer is £15. Hope this helps and is clear enough.
