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 =
Putting values, we get:
Thus, the radius of the new cheese ball formed is approximately 6.603 inches.
Answer:
So a bag of chip costs $2.39
Step-by-step explanation:
Let x = cost of a bag of chip
Let y = cost of a box of pretzel
Micheal buys two bags of chips and three boxes of pretzels for $5.13
This means
2x + 3y = 5.13 - - - - - - - - - -1
He then buys another bag of chips and 2 boxes of pretzels for $3.09
This means
x + 2y = 3.09 - - - - - - - - - - - -2
Solving equation 1 and equation 2 simultaneously and using the elimination method,
Multiply equation 1 by 1 and equation 2 by 2
2x + 3y = 5.13
2x + 6y = 6.18
Subtracting,
-3y = -1.05
y = -1.05/-3= $0.35
Put y= 0.35 in equation, x + 2y = 3.09
x + 2(0.35)= 3.09
x + 0.7= 3.09
x = 3.09-0.7 = $ 2.39
So a bag of chip costs $2.39
It already is in simplest form because the numerator and denonimator don't have a common factor to then divide them by.
