For a party, three solid cheese balls with diameters of 2 inches, 4 inches, and 6 inches, respectively, were combined to form a
schepotkina [342]

Answer:

The radius of the new cheese ball formed is approximately 6.603 inches.

Step-by-step explanation:

We are given the following in the question:

Radius of three cheese ball = 2 inches, 4 inches, and 6 inches

They were combined to form a new cheese ball.

Thus, we can write

Volume of three cheese balls =  Volume of new cheese ball.

Let r be the radius of new cheese ball.

Volume of sphere =

\displaystyle\frac{4}{3}\pi r^3

Putting values, we get:

\displaystyle\frac{4}{3}\pi r_1^3 + \displaystyle\frac{4}{3}\pi r_2^3 +\displaystyle\frac{4}{3}\pi r_3^3 =\displaystyle\frac{4}{3}\pi r^3\\\\\frac{4}{3}\pi(2^3 + 4^3 + 6^3) = \displaystyle\frac{4}{3}\pi r^3\\\\2^3 + 4^3 + 6^3 = r^3\\\Rightarrow 288 = r^3\\\Rightarrow r = (288)^{\frac{1}{3}}\\\Rightarrow r \approx 6.603

Thus, the radius of the new cheese ball formed is approximately 6.603 inches.

Really easy math question

Number of sodas sold = 130

Number of hot dogs sold = 65

Step-by-step explanation:

Given,

Combined number of sodas and hot dogs sold = 195

Let,

x represent the number of sodas sold

y represent the number of hot dogs sold

According to given statement;

x+y=195     Eqn 1

x = 2y        Eqn 2

Putting value of x from Eqn 2 in Eqn 1

2y+y=195\\3y=195

Dividing both sides by 3

\frac{3y}{3}=\frac{195}{3}\\y=65

Putting y=65 in Eqn 2

x=2(65)\\x=130

Number of sodas sold = 130

Number of hot dogs sold = 65
