Answer:

I put all the steps down. I don't know which one you want. I hope you understand it now.

Step-by-step explanation:

Megan bought 2 1/4 pounds of bananas for $0.80 per pound and 1 1/2 pounds of strawberries for $1.10 per pound. How much more did
Dennis_Churaev [7]

Answer:

$0.15

Step-by-step explanation:

Cost of each pounds of banana = $0.80

Number of pounds of banana = 2 1/4 pounds

Total cost of banana = $0.80 × 2 1/4 pounds

= 0.80 × 9/4

= 0.80 × 2.25

= 1.8

Total cost of banana = $1.8

Cost of each pounds of strawberry = $1.10

Number of pounds of strawberry = 1 1/2 pounds

Total cost of strawberry = $1.10 × 1 1/2 pounds

= 1.10 × 3/2

= 1.10 × 1.5

= 1.65

Total cost of strawberry = $1.65

How much more did Megan spend on bananas than on strawberries?

Total cost of banana - Total cost of strawberry

= $1.8 - $1.65

= $0.15

A right circular cylinder has a height of 20 1/2 ft and a diameter 1 1/5 times its height.
AfilCa [17]
  • Height=h=20-1/2=20.5ft
  • Diameter=1-1/5=1.2
  • Radius=1.2/2=0.6ft

\\ \sf\longmapsto V=\pi r^2h

\\ \sf\longmapsto V=3.14(0.6)^2(20.5)

\\ \sf\longmapsto V=3.14(0.36)(20.5)

\\ \sf\longmapsto V=23.17ft^3

Y= f(x)=2x find f(x) when x=2
mina [271]

According to the problem, y = f(x) = 2x

Here the value of x = 2.

We have to put the value of x in place of x in 2x to calculate the actual value of 2x.

Therefore, after putting the value of x in 2x we get 2x = 2 x 2 = 4

This means the value of 2x is 4. This is because we have included the given value of x to get the value of 2x.

Again the value of f(x) = 2x.

Therefore, the value of f(x) = 2x = 4.
