Cerial: $3.14 for 11.2oz;
Cookies: $5.04 for 18 cookies;
Eggs: $2.04 for half dozen;
Grapes: $9 for 5lbs;
Orange juice: $2.08 for 16oz;
Watermelon: $3.72 for 4lbs.
The way to solve for these or to check is by dividing the price by the amount. For Cookies, $5.04 is best because [ 5.04 / 18 = $0.28/cookie ] and not $4.50 because [ 4.50 / 15 = $0.30 / cookie. ]. Hopefully this helps!
He is incorrect. you first have to find the least common denominator and that is 6. so then you would have 3/6- 2/6. that would equal 1/6.
Answer:
For 90 minutes of TV there will be 24 mins of commercials
Step-by-step explanation:
You start with 30 and keep adding 30 mins each time until you get to 90. (So..30..60..90) each time you add 30mins you add 8 more minutes to the commercials)
30 mins tv----8mins commercials
60 mins tv----16mins commercials
90 mins tv----24mins commercials
Hope this helps, good luck!
Yes! It is correct!!!!!!!
Answer:
<h3>19,133.067</h3>
Step-by-step explanation:
Volume of the ball (spherical in nature) Vb = 4/3πrb³
Volume of the hole Vh = 4/3πrh³
rb is the radius of the ball
rh is the radius of the hole
If a ball of radius 17 has a round hole of radius 7 drilled through its center, the volume of the resulting solid will be expressed as:
V = Vb - Vh
V = 4/3πrb³ - 4/3πrh³
factor out the like terms;
V = 4/3π(rb³-rh³)
Given
rb = 17
rh = 7
V = 4/3π(17³-7³)
V = 4/3π(4913-343)
V = 4/3π(4570)
V = (4π*4570)/3
V = 57,399.2/3
V = 19,133.067
Hence the volume of the resulting solid is 19,133.067
