Answer:
yes, it uses the same ratio of flour and milk.
Step-by-step explanation:
A pancake recipe calls for 4 cups of flour and 3 cups of milk.
The ratio of flour and milk for the recipe = 4 : 3
The ratio of flour and milk for the recipe calling for 2 cups flour and 1.5 cups of milk = 2 : 1.5
In order to solve the ratio we convert it into a fraction.
Therefore, 2 : 1.5 =
removing the decimal, 2:1.5 =
=
= 4 : 3
Hence yes, it uses the same ratio of flour and milk.
the pancake recipe calls for a ratio of 4:3 flour to milk
the other recipe is 2:1.5 flour to milk
if you multiply both the flour and the milk in the 2nd recipe by 2
it becomes 4:3 flour to milk
just like converting amounts of recipes
if you change the denominator so that it is equal to the original recipe
the numerator has to change with it giving you an exact comparison

Answer:
6 pounds.
Step-by-step explanation:
70-25.36= 44.64 (the amount of money she spent)
44.64/7.44 (per pound cost)= 6
Answer:
Rachel bought 6 pounds of coffee.
Step-by-step explanation:
First, do $70-$25.36, because that will give you the total amount of money she spent on coffee.
$70-$25.36= $44.64.
Rachel spent $44.64 on coffee.
Next, you know that every pound of coffee costs $7.44.
So, $7.44x = $44.64
x= the number of pounds of coffee Rachel purchased.
So, we have to now isolate x.
$7.44x / $7.44 = $44.64 / $7.44
x= 6
Therefore, Rachel purchased 6 pounds of coffee.

Circumference:
2*π*radius.
2*3.14*5
31.4
Circumference = 31.4
Surface area:
Substitute the values of the radius (r=5), the height (h=9), and an approximation for π(3.14) into the formula.
SA=2(3.14)(5)^2+2(3.14)(5)(9)
Simplify each term.
SA=157+282.6
Add 157 and 282.6 to get 439.6.
Surface area=439.6cm^2
Volume:
Substitute the values of the radius (r=5), the height (h=9), and an approximation of Pi (3.14) into the formula to find the volume of the cylinder.
V≈3.14⋅5^2⋅9
Raise 5 to the power of 2 to get 25.
V≈+3.14⋅25⋅9
Simplify
Volume = 706.5cm^3

Circumference=56.52
Surface area:
Substitute the values of the radius (r=9), the height (h=24), and an approximation for π(3.14) into the formula.
SA=2(3.14)(9)^2+2(3.14)(9)(24)
Simplify each term.
SA=508.68+1356.48
Add 508.68 and 1356.48 to get 1865.16.
Surface area = 1865.16in^2
Volume:
Substitute the values of the radius (r=9), the height (h=24), and an approximation of Pi (3.14) into the formula to find the volume of the cylinder.
V≈3.14⋅9^2⋅24
Raise 9 to the power of 2 to get 81.
V≈+3.14⋅81⋅24
Multiply 3.14 by 81 to get 254.34.
