the first thing to note is since one gallon= 60 miles then 1/2 gallon= 30 miles, now I know 1/2 is not an answer but it is easiest to decrease in moderate amounts. 1/2 gallon= 48 Km so we are close, and 1/2=0.5 so if we brought it down to 0.42 we would have 25.2 miles and 25.2 miles = 40.32. The question wants to know the approximate number and 40.32 is the closest we are going to get so the answer is 0.42

question 3

Answer:

80 + 65x ≤ 425

Step-by-step explanation:

First of all we know that the 425 must be greater than or equal to the other side, so the symbol to show that would be ≤. We also know that the forklift is a fixed price by the words 'each day'. And the to hire a single crew member would be $65 unless there are more crew workers, which would be multiplied with the 65.

question 4

Jimthompson5910Expert

Part A

Yes y is a function of x. Specifically the equation is y = x^5

For any given input, there is exactly one output

Notice how if x = 1 then y = x^5 = (1)^5 = 1

Notice how if x = -1 then y = x^5 = (-1)^5 = -1

Notice how if x = -2 then y = x^5 = (-2)^5 = -32

Notice how if x = 2 then y = x^5 = (2)^5 = 32

In general,

x^5 = x*x*x*x*x

there are five copies of x multiplied

A more specific example

3^5 = 3*3*3*3*3

there are five copies of '3' multiplied

=====================================================

Part B

All we do is replace x with 4 and use PEMDAS to simplify

f(x) = 2x+12

f(4) = 2(4)+12

f(4) = 8+12

f(4) = 20

The value of f(4) is 20

What does it mean? It is the total cost of renting the bowling lane for 4 hours. If you rent it for four hours, then you'll pay a total of $20. 

The portion 2x = 2*4 = 8 is the variable cost which depends on how long you play. The more hours, the more the variable cost goes up

The fixed cost is 12. This is always fixed as this is the price to get in the door. If you play for 0 hours, but somehow got in the door, then you still pay $12

In total, variableCost+fixedCost = 8+12 = 20 = totalCost

What is the y-intercept of the line -7x-5y=-45?
Goshia [24]

Answer:

The y-intercept is at the point (0, 9).

Step-by-step explanation:

WE have the y intercept when x = 0:

-7(0) - 5y = -45

-5y = -45

y = -45/-5 = 9.

please help me- this along with the last one and many more are worth a project grade and i need to pass school- quq
Alex

Each person would get \frac{5}{8} pizza.

Solution:

Total quantity of pizza = 1\frac{7}{8}

Number of persons shared = 3

To find how much pizza would each person get:

Let us first convert  improper fraction into mixed fraction.

$1\frac{7}{8}=\frac{1\times8 + 7}{8}=\frac{15}{8}

Now divide the total quantity of pizza by the number persons shared.

$\text{Quantity of pizza each person get}=\frac{(\frac{15}{8}) }{3}

                                                    $=\frac{15}{8\times3}

                                                    $=\frac{15}{24}

Divide both numerator and denominator by 3.

                                                    $=\frac{15\div3}{24\div3}

                                                    $=\frac{5}{8}

Quantity of pizza each person get = \frac{5}{8}

Hence each person would get \frac{5}{8} pizza.
