Marina86 [1]

Answer : The correct option is, (A) 10

Step-by-step explanation :

First we have to calculate the volume of cylinder shaped can.

Formula used:

Volume of cylinder = π r² h

where,

r = radius of cylinder

h = height of cylinder

Given:

Diameter of cylinder = 3 in

Height of cylinder = 6 in

Radius of cylinder = $\frac{Diameter}{2}=\frac{3in}{2}=1.5in$

Now putting all the given values in the above formula.

Volume of cylinder = π r² h

Volume of cylinder = 3.14 × (1.5 in)² × 6 in

Volume of cylinder = 42.39 in³

Now we have to determine the number of soda cans are in a pack.

Number of soda cans are in a pack = $\frac{\text{Volume of soda pack}}{\text{Volume of cylinder shaped can}}$

Number of soda cans are in a pack = $\frac{423.9in^3}{42.39in^3}$

Number of soda cans are in a pack = 10

Therefore, the number of soda cans in a pack are 10.

What are two fractions equal to 2/5?

ycow [4]

4/10 and 6/15. I got these answers by multiplying the numerator and denominator by 2 to get 4/10 and then multiplied the numerator and denominator by 3 to get 6/15. If you were to simplify these fractions completely, you would be left with the original fraction, 2/5.

Firlakuza [10]

Answer:

Jenna spent 7 hours babysitting.

Step-by-step explanation:

With the information provided, you can say that Jenna's total earnings are equal to the amount she earned cleaning her neighbor's basement plus the result of multiplying the charge per hour for babysitting for the number f hours, which is:

e=20+5x, where:

e represents the total earnings

x is the number of hours

Now, you can replace e with 55 that is the toal amount she earned and solve for x:

55=20+5x

55-20=5x

35=5x

x=35/5

x=7

According to this, the answer is that Jenna spent 7 hours babysitting.
