Step-by-step explanation: cost =422+3x, where x= number of miles covered

Earnings=400+5x

St break even, cost = earnings, then solving the linear equation, by collecting like terms, and dividing through by 22. x=11, the Pu x=11 in the either the cost or earnings expressing to get 455

Answer:

y = x³

Step-by-step explanation:

Note that

1³ = 1 × 1 × 1 = 1 ← value of y- coordinate

2³ = 2 × 2 × 2 = 4 × 2 = 8 ← value of y- coordinate

3³ = 3 × 3 × 3 = 9 × 3 = 27 ← value of y- coordinate

4³ = 4 × 4 × 4 = 16 × 4 = 64 ← value of y- coordinate

5³ = 5 × 5 × 5 = 25 × 5 = 125 ← value of y- coordinate

The rule is that the y- coordinate is the cube of the x- coordinate, that is

y = x³

Onondaga Electronics operates on a net-profit rate of 20% on its printer cables. If the markup is $8.95 and the overhead is $4.3

asambeis [7]

Answer:

The selling price be $79.56 .

Step-by-step explanation:

Let us assume that the cost price be x.

As given

If the markup is $8.95 and the overhead is $4.31 .

Selling price = Cost price + Markup price + Overhead price

= x + 8.95 + 4.31

= x + 13.26

Profit = Selling price - Cost price

= x + 13.26 - x

= $ 13.26

Formula

$Profit\ percentage = \frac{Profit\times 100}{Cost\ price}$

Putting the values in the above formula

$20= \frac{13.26\times 100}{x}$

$x= \frac{13.26\times 100}{20}$

$x= \frac{1326}{20}$

x = $ 66.3

Thus cost price be $66.3 .

Thus

Selling price = $66.3 + $13.26

= $ 79.56

Therefore the selling price be $79.56 .

A commercial building has seven levels of car parking spaces. Each level has four rows and each row has 38 car spaces. How many

tatyana61 [14]

So, all we have to do here is multiply:

First, the amount of car spaces by the amount of rows:

38 x 4 = 152

This is the number of parking spots per level.

Then, the number of levels by the number of parking spots on each level:

152 x 7 = 1064

So, a total of 1,064 cars can be parked in this building!

If y varies directly as x, and y is 400 when x is randy is r when x is 4, what is the numeric constant of variation in this rela

juin [17]

The numeric constant of variation is 100

Step-by-step explanation:

Direct proportion means that increase in one variable cause increase in other variable

Here,

It is given that

y varies directly as x

y∝x

when the proportionality symbol is removed a proportionality constant is introduced

$y = kx$

Given that

y = 100 when x = 4

Putting the values

$400 = k * 4\\k = \frac{400}{4}\\k = 100$

The numeric constant of variation is 100
