Find all the number in the set that are less than -7.
The 'bigger' the negative number seems, the smaller it is.
So -15, -10.5, and -7.2 are all less than -7.
Answer:
Part 1 : 
Part 2 : Half life is 84 minutes ( approx )
Step-by-step explanation:
Part 1 : Suppose the function that shows the amount( in grams ) of the substance after t minutes,

If t = 0 min, A = 250 grams,


If t = 250, A = 32 grams,



Taking ln both sides,


Hence, the equation that shows this situation,

Part 2 : If A = 250/2 = 125,


Taking ln both sides,


Therefore, the half life of the substance would be 84 minutes.
Answer:
A - They Have Too Much Caramel
Step-by-step explanation:
Ari likes 3 oz caramel for 5 scoops ice cream.
Freeze Zone makes 6 oz caramel with 8 scoops of ice cream.
Divide both amounts of Freeze Zone by 2.
6 oz caramel for 8 scoops of ice cream is the same ratio as
3 oz caramel for 4 scoops of ice cream.
Since Ari likes 3 oz caramel for 5 scoops ice cream,
he will think it's too much caramel for the ice cream.
Answer: A - They Have Too Much Caramel
Answer:
Step-by-step explanation:
Answer: c)She should have multiplied 15 by 3 instead of dividing.
Step-by-step explanation:
Number of quilts Ruby plan to make in one month= 3
which means if Ruby makes more than 3 quilts, the time will be more than 1 month.
To find the number of months to make 15 quilts, she need to divide 15 by 3
Thus, the number of months to make 15 quilts=5
Her answer was 1/5 which was absolutely wrong as if she is making 3 quilt in 1 month then in 1/5 month she would make fewer than 3 quilts.
She divides 3 by 15 instead of 15 by 3, thus but the unit is quilts not months.
Thus the only wrong option is c)She should have multiplied 15 by 3 instead of dividing.
