Answer:
Gina 2.5 * 1.38 = $3.45
Amy 3.5 * .98 = $3.43
Gina spent more money by .02
Step-by-step explanation:
There are 45 pounds and 30 pounds of each type respectively.
Step-by-step explanation:
Since we have given that
Cost of first type = $2 per pound
Cost of second type = $7 per pound
Cost of mixture = $4 per pound
So, we need to find the quantity of each type to make 75 pounds of a blend.
We will use "Mixture and Allegations":
First type Second type
2 7
4
---------------------------------------------------
7 - 4 : 4 - 2
3 : 2
So, Quantity of first type would be

Quantity of second type would be

Hence, there are 45 pounds and 30 pounds of each type respectively.
so, we know both the rectangular prism and the cylinder got filled up to a certain height each, the same height say "h" cm.
we know the combined volume of both is 80 cm³, so let's get the volume of each, sum them up to get 80 then.

Answer:
t= - 48
Step-by-step explanation:
t/8 - 6= -12 add 6 to both side
t/8= -6 multiple by 8
t= -48
