Answer:

Step-by-step explanation:

let the number be 'x'

95 % of x = 38

(95 / 100)x =38

x = 38 × 100 / 95

x = 2 × 100 / 5

x = 2 × 20

x = 40

PLEASE HELP ME WITH THIS I NEED TO GET IT DONE WITH

stepan [7]

Answer:

Correct answer: V = 82.5 in³

Step-by-step explanation:

This is a regular five sided prism.

Given:

The base edge a = 4 in

The radius of the inscribed circle or the height of an isosceles triangle

Ri = h = 2.75 in

Prism height H = 3 in

The base consists of five isosceles triangles

The area of one triangle is:

A₁ = a · h / 2

The area of the base is:

B = 5 · A₁ = 5 · a · h / 2

B = 5 · 4 · 2.75 / 2 = 27.5 in²

The volume of the prism is:

V = B · H = 27.5 · 3 = 82.5 in³

V = 82.5 in³

A man drove x miles per hour for 3e hours and (2x-60) miles per hour for the next 4.75 hours. Express the total distance he trav

avanturin [10]

Answer:

A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.

Total distance covered by the man in terms of 'x' = (12.5x-285)miles

Step-by-step explanation:

Given:

Speed of a man = 'x' miles/hour

Time taken = $3$ hour

So, distance = product of speed and time.

Distance covered in term of 'x' $=(d_1=3x)$

Now,

Speed = $(2x-60)$ miles/hour

Time taken= $4.75$ hours

Distance $(d_2)$ = $(2x-60)\times 4.75$

= $(2x\times 4.75) -(60\times 4.75)$

= $(9.5x - 285)$ miles

Total distance covered by the man = Summation of $d_1$ and $d_2$

= $(9.5x-285+3x)$

= $(12.5x-285)$ miles

So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.

Which of these pairs of costs and revenues could a company have if it's at its<br> break-even point?

sertanlavr [38]

Answer:

At break even cost = revenue

Step-by-step explanation:

A company is said to be at break even if the cost of producing an item is equal to the revenue generated from the sell of that item, that means there is no loss or gain.

If the cost function C(x) = 200 + 10x and the revenue function R(x) = 60x - x², where x is the amount of items produced. At break even, R(x) = C(x)

60x - x² = 200 + 10x

x² - 60x + 10x + 200 = 0

x² - 50 x + 200 = 0

x = 46 or x = 4 is the break even point

Matt and his dad are building a tree house. They buy enough flooring material to cover an area of 36 square ft. What are all pos

vodomira [7]

Answer:

Factor pairs of 36 are ...

1×36, 2×18, 3×12, 4×9, 6×6 . . . and the reverse of these

There is nothing in the problem statement limiting the dimensions to integer numbers of feet, so any dimensions x and 36/x will do. (x in feet)

Step-by-step explanation:

Area is the product of length and width. The desired dimensions are the length and width of the floor, so any pair of numbers resulting in a product of 36 will be a possible set of dimensions.

If the dimensions are supposed to be integer numbers of feet, then the possibilities for length×width are ...

1×36, 2×18, 3×12, 4×9, 6×6, 9×4, 12×3, 18×2, 36×1

_____

As a practical matter, the tree house probably needs to be wider than 2 feet, leaving 3×12, 4×9, and 6×6 as possible dimensions (length×width or width×length). Depending on the flooring material and the difficulty of cutting it, there may be other limitations on the dimensions.
