Answer:
Step-by-step explanation:
What this question is asking of you is what is the greatest common divisor of 12 and 15. Or, what is the biggest number that divides both 12 and 15.
in order to find this we have to split each number into it's prime components.
for 12 they are 2,2 and 3 (
2
⋅
2
⋅
3
=
12
)
and for 15 they are 3 and 5 (
3
⋅
5
=
15
)
Out of those two groups (2,2,3) and (3,5) the only thing in common is 3, so 3 is the greatest common divisor. That tells us that the greatest number of groups that can exist and have the same number of girls and the same number of boys for each group is 3.
Now to find out how many girls and boys there are going to be in each group we divide the totals by 3, so:
12
3
=
4
girls per group, and
15
3
=
5
boys per group.
(just as a thought exercise, if there were 16 boys, the divisors would have been (2,2,3) and (2,2,2,2), leaving us with 4 groups [

] of 3 girls [12/4] and 4 boys [16/4] )
Q20) c < 82-76
c < 6

Answer:I think it would be $9
Step-by-step explanation:
50% of 20 is $10
10% of $10 is $1
Subtract 1 from 10, which gives you $9
<u>Cold Farms: </u>
<u>Small box </u>
1 pint = $2.50
1 quart = $4.50
<u>Large Box</u>
1 quart = 2 pints .
2 pints = $4.50
1 pint = $4.50 / 2 = $2.25
<u>Cone Dreams:</u>
<u>Small box </u>
1 quart = $4.25 and
1 pint = $4.25/2 = $ 2.125
<u>Large Box</u>
1 gallon = $9.50.
1 gallon = 8 pints
8 pints = $9.50.
1 pint = $9.50 / 8 = $ 1.1875.
<h3>15) Therefore, large size container of Cold Farms ice cream is better deal for Sheldon because it cost $2.25 per pint of ice cream as compared to small box cost
$2.50 per pint.</h3><h3 /><h3>16) Cone Dreams Large size container cost just $ 1.1875 per pint of ice cream. So, Cone Dreams Large size container is best deal.</h3>
The rate of change is also called the slope
the formula foe the rate of change is (y2-y1) / (x2-x1)
x1 = -3
x2 = 6
y1 = 14
y2 = -1
rate of change = (-1 - 14) / (6- (-3)
= -15 / 9
= -5/3
