A local gym instructor has a course load that allows her to teach eight classes. At an interest meeting, 8 people wanted high-‐

cricket20 [7]

Answer:

The final curse load of the local gym instructor is this:

High-‐impact aerobics = 1

Low-‐impact aerobics = 4

Jazzercise = 1

Step exercise = 2

Step-by-step explanation:

1. Let's apportion the class load using the Hamilton method

Number of classes the local gym instructor can teach = 8

Total number of students that want to take a class = 114 (8 people wanted high-‐impact aerobics, 64 wanted low-‐impact aerobics, 11 wanted jazzercise, and 31 wanted step exercise)

Standard divisor = 114/8 = 14.25

Now, we can apportion the students in in Standard quotas, this way:

High-‐impact aerobics = 8/14.25 = 0.5614

Low-‐impact aerobics = 64/14.25 = 4.49

Jazzercise = 11/14.25 = 0.7719

Step exercise = 31/14.25 = 2.1754

Now, we find the Minimum quota, just considering the whole number and don't taking into account the decimals, this way:

High-‐impact aerobics = 0

Low-‐impact aerobics = 4

Jazzercise = 0

Step exercise = 2

As we can see we have 6 classes and there are 2 still pending. Those 2 goes to the classes with the highest decimal portion, in this case, Jazzercise .7719 and High-‐impact aerobics with .5614.

The final course load is this:

High-‐impact aerobics = 1

Low-‐impact aerobics = 4

Jazzercise = 1

Step exercise = 2

A rectangular auditorium seats 1302 people. The number of seats in each row exceeds the number of rows by 11. Find the number of

sveticcg [70]

Number of seats = 42

Seats per row x row = 1302
s x r = 1302

rows + 11 = seats per row
r + 11 = s

s x r = 1302
(r + 11) x r = 1302
r^2 + 11r = 1302
r^2 + 11r - 1302 = 0
(r + 42) x (r - 31) = 0
r = -43 or 31

Cannot have negative rows so the number of rows is 31, and the number of seats per row is 31 + 11 = 42

Check: 31 x 42 = 1302 :)

The great Pyramid outside Cairo, Egypt, has a square base measuring 756 feet on a side and a height of 480ft

Vlada [557]

Answer:

V = 3,386,880 cubic yards

V = 91445760 cubic feet

V = (1/3) · b2 · h so 1/3 x 756^2 x 480 = 91445760 ft^3

Answer = 91445760 ft^3

Step-by-step explanation:

converting feet into yards

let

1 yard = 3 ft

1 ft = (1/3) yard

a = 756 ft = 756*(1/3) yards the length of the side of the square base

h = 480 ft = 480*(1/3) yards the height of the pyramid

a.) the volume of the pyramid V = (a^2*h)/3 = (a^2*h)(1/3)

V = (756*(1/3))^2*480*(1/3)*(1/3)

V = 3,386,880 cubic yards
