Apples are on sale at the grocery store at a price of 8 apples for $4.00 .Mark buys 12 apples. If he is charged the sale price for apples, how much will Mark pay?

Answers

Answer 1
Answer: You can do this problem 2 ways.  Whichever works easier for you:

Take the cost of 8 apples and divide it by 8 in order to find a per apple cost
4/8 = $.50 per apple
Then multiply the total number of apples by the cost per apple
12 * $.50 = $6.00 paid

Or

You can divide the total number of apples by 8 to find how many units of apples you have

12/8 = 1.5

Then multiply the number of units by the cost for 1 unit (8 apples)

1.5*$4 = $6.00

Mack designed a water fountain with a square pyramid flowing into a cube. The edges of the bases of the pyramid and the cube have the same length and the heights of the pyramid and the cube are the same. Describe the relationship between the volume of the cube and the volume of the pyramid.

Please help me on this question. There are six questions in total and I did the rest (finding the volume/surface area) but this one I just don't understand. I'm willing to give up 60 of the 70 points I have for help (help that tells me the answer and explains it). Maybe even all 70. Please help if you understand. Thank you, minna.

Answers

volume of pyramid = 1/3 b2h
volume of  cube = b3

now , provided pyramid and cube have same edges and same heights.

thus, volume of pyramid = 1/3 b3
volume of cube = b3.

thus, ratio = 1/3b3/ b3 = 1/3.

Thus, volume of pyramid = 1/3volume of cube
V_(cube)=a^3\ \ \ and\ \ \ V_(pyramid)= (1)/(3) \cdot a^2\cdot h=(1)/(3)a^3\n \n (V_(pyramid))/(V_(cube)) = ((1)/(3)a^3)/(a^3)= (1)/(3)\n \n \nA_(cube)=6a^2\n \nh^2=a^2+( (1)/(2) a)^2\ \ \ \Rightarrow\ \ \ h^2= (5a^2)/(4)\ \ \ \Rightarrow\ \ \ h= (a √(5) )/(2)\n\nA_(pyramid)=a^2+4\cdot (1)/(2)ah=a^2+2a\cdot (a √(5) )/(2) =a^2(1+ √(5)) \n \n (A_(pyramid))/(A_(cube))= (a^2(1+ √(5)) )/(6a^2) = (1+ √(5))/(6)

the distance between Columbus Ohio and New York City is about 560 miles how many hours would it take the train to travel between cities

Answers

The number of hours the train took to travel between the two cities is 2.09 hours.

Given that,

The distance between Columbus, Ohio, and New York City is about 560 miles.

And, The train travels 268 miles an hour.

We need to find out how many hours would it take the train to travel between the two cities.

Here, the train speed is,

= 268 miles per hour

And, the distance between the two cities.

= 560 miles

We have,

268 miles = 1 hour

Multiply both sides by 560

560 x 268 miles = 560 x 1 hour

Divide both sides by 268

560 miles = (560/268) x 1 hour

560 miles = 2.09 hours

Hence, the train will take 2.09 hours to travel 560 miles,

The complete question is,

The distance between Columbus, Ohio, and New York City is about 560 miles how many hours would it take the train to travel between the two cities The train travels 268 miles an hour.

2144 miles in 8 hours. In 1 hour = 2144 / 8 = miles in 1 hour and that = 268

NEED HELP FAST PLEASE URGENT!!!!( the James family went out to eat and their total bill was $110. Since the service was great, they will leave a 20% tip. How much money should the family leave for tip? Answer is in money format and should include the dollar sign in front of the solution)

Answers

The family should leave $22

All we have to do is multiple 110 by 0.20 to get the answer.

If we multiple the two numbers, we get the number 22, so the James family should leave a $22 tip.

By the by, if we combine the two numbers, we get 132, meaning that the James family will spend $132 in total.
