Hello, i really appreciate your ! !
tricia uses the fermi process to estimate the number of buckets of sand she could store in a warehouse. the buckets are shaped like cylinders. the warehouse is shaped like a rectangular prism.
she estimates the buckets have a height of 15 inches and a diameter of 20 inches.
she estimates the warehouse is 250 feet long, 80 feet wide, and 20 feet high.
which expression should tricia use in the process?
a) 7×10^9/5×10^4
b) 5×10^6/5×10^3
c) 7×10^8/5×10^3
d) 5×10^7/5×10^4

  C)  7×10^8/(5×10^3)

Step-by-step explanation:

In cubic inches, the volume of a bucket of sand is ...

  (π/4)(20 in)²(15 in) = 1500π in³ ≈ 5×10^3 in³

__

The volume of the warehouse is

  (250 ft)(80 ft)(20 ft) = 400,000 ft³ = 4×10^5 ft³

The conversion to cubic inches is ...

  (4×10^5 ft³)(1728 in³/ft³) = 4×1.727×10^8 in³ ≈ 7×10^8 in³

Dividing the warehouse volume by the bucket volume gives the approximate number of buckets that will fit in the warehouse:

  (7×10^8)/(5×10^3) . . . . . matches choice C

7x10^8/5x10^3

Step-by-step explanation: I got it correct on the test :)

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
