The Cholula pyramid in Mexico has a height of approximately 217 feet and a base approximately 1476 feet by 1476 feet.The Cheops pyramid(part of the great pyramids) is taller with an approximate height of 480 feet but with a 755 feet by 855 feet base. Determine which pyramid has the most volume

Answers

Answer 1
Answer: To solve this problem you must apply the proccedure shown  below:

 1- You must apply the formula for calculate the volume of a square pyramid and the formula for calculate the volume of a rectangular pyramid.

 2- You have that the Cholula pyramid in Mexico has a height of approximately 217 feet and a base approximately 1476 feet by 1476 feet. Therefore, it is a square pyramid. So, you have:

 V1=(a^2)h/3
 V1=(1476 feet)^2(217 feet)/3
 V1=1.58x10^8 feet^3

 3- The Cheops pyramid has an approximate height of 480 feet and 755 feet by 855 feet base. It is a rectangular pyramid:

 V2=lwh/3
 V2=(855 feet)(755 feet)(480 feet)/3
 V2=1.03x10^8 feet^3

 The answer is: The Cholula pyramid has the most volume.

A bad contains 42 cups of dog food your dog eats 2 1/3 cups of dog food each day how many days does the bag of dog food last

Answers

It will last 18 days
In this situation, you are dividing 42 by 2 1/3. What you would need to do is make 2 1/3 an improper fraction. You'd multiply the denominator by the whole number and then add the numerator. Once
you get that (It's 7), you would use the same denominator as the original fraction. Now you would use what I call, the keep, change and flip method. That is basically making 42 a fraction (42/1), changing the division sign into a multiplication sign, and flipping the numerator and denominator so that it will be 3/7. You then evaluate the equation, and your answer should be 126/7. To get the amount of days the bag of dog food will last, you need to divide 126÷7. You will see 18 and a bunch of numbers after a decimal, but just use 18 as your answer. Hope this will help you!

In Bisbee, Arizona, an old mining town, you can buy souvenir nuggets of gold, silver, and bronze. For $20, you can buy any of the following mixtures of various nuggets: (a) 14 gold, 20 silver, and 24 bronze

(b) 20 gold, 15 silver, and 19 bronze

(c) 30 gold, 5 silver, and 13 bronze



Write the Systems of Equations to represent these equations.



(There are Three answers)

14g + 15s + 13b = 20
30g + 5s + 13b = 20
5g + 13s + 20b = 30
24g + 15s + 14b = 5
20g + 15s + 19b = 20
14g + 20s + 24b = 20
30g + 15s + 24b = 20
20g + 20s + 20b = 20

Answers

Let g dollars be the price of gold nuggets, s dollars - the price of silver nuggets and b dollars - the price of bronze nuggets.

1)

  • If 1 gold nuggets costs $g, then 14 gold nuggets cost $14g;
  • If 1 silver nuggets costs $s, then 20 silver nuggets cost $20s;
  • If 1 bronze nuggets costs $b, then 24 bronze nuggets cost $24b.

In total they cost $20, then

14g+20s+24b=20.

2)

  • If 1 gold nuggets costs $g, then 20 gold nuggets cost $20g;
  • If 1 silver nuggets costs $s, then 15 silver nuggets cost $15s;
  • If 1 bronze nuggets costs $b, then 19 bronze nuggets cost $19b.

In total they cost $20, then

20g+15s+19b=20.

3)

  • If 1 gold nuggets costs $g, then 30 gold nuggets cost $30g;
  • If 1 silver nuggets costs $s, then 5 silver nuggets cost $5s;
  • If 1 bronze nuggets costs $b, then 13 bronze nuggets cost $13b.

In total they cost $20, then

30g+5s+13b=20.

Emilio paid $287.50 in taxes to the school district that he lives in this year. This year’s taxes were a 15% increase from last year. What did Emilio pay in school taxes last year? PLEASE HELP

Answers

Let the Taxes she paid last year be 'x'
So percentage increase = 15% of x
= 15x/100

So,
this year's taxes = Last year's taxes + increment
287.50 = x + 15x/100
287.5 = 115x/100
x = 250

So, she paid $250 as taxes last year.
