Okay so its really simple you just add all your numbers together and you have your answer so i came up with 2,620
To estimate the volume, you will use the formula for finding volume of a pyramid.
You will need to convert the height, given in feet, to yards.
(48 x 10)/3= 160 yards
You also need to convert the area of the base to square yards.
571536 ft.²/ 9 ft.² (1 square yd)= 63,504 yd.².
V = 1/3 BH, where B is the area of the base.
V = 1/3 x 63504 x 160
V = 3,386880 cubic yards
The approximate volume of The Great Pyramid is 3,386,880 yd.³.
Answer:
Present Time
Let X= Eric's age (4/5)X= Seth's age
Question: What are their ages now?________________________________________________________________________
Past (21 years ago)
X-21 =Eric's age (4/5)X-21=Seth's age
2*[4/5(X-21]=Eric's age
Therefore, X-21= 2*[4/5(X)-21]=Eric's age Substitution
_______________________________________________________________________
X-21= 8/5 X - 42 Solve for "X" by adding 42 to both sides.
X-21+42=(8/5) X
X+21 = (8/5)X Subtract "X" from both sides.
21=(3/5)X Multiply both sides of equation by reciprocal of (3/5), which is 5/3
21*(5/3)= X Finish the problem to find value of "X," which is Eric's age.
Then find 4/5 (X)= Seth's age
Answer:
5/2
Step-by-step explanation:
The scale factor for linear measures, such as perimeter, is the square root of the scale factor for areas. The ratio of larger area to smaller is ...
... 75/12 = 25/4
so the ratio of the larger perimeter to the smaller is ...
... √(25/4) = 5/2
