6 points Emily’s family needs to rent a moving truck to move their belongings to a different house. The rental cost for Trucks-A

Alexxx [7]

Answer/Step-by-step explanation:

Equation to represent the daily rental cost for each type of truck can be written as follows:

Daily rental cost for Trucks-A-Lot = 42 + 0.72m

Daily rental cost for Move-in-Truckers = 70 + 0.12m

Where, m = Emily's mileage

To determine the number of miles for which the truck cost the same amount, set both equations equal to each other and solve for m.

$42 + 0.72m = 70 + 0.12m$

Collect like terms

$0.72m - 0.12m = 70 - 42$

$0.6m = 28$

Divide both sides by 0.6

$\frac{0.6m}{0.6} = \frac{28}{0.6}$

$m = 46.7$

At approximately 47 miles, both trucks would cost the same amount.

Check:

Daily rental cost for Trucks-A-Lot = 42 + 0.72m

Plug in the value of x = 47

= 42 + 0.72(47) = $75.84 ≈ $76

Daily rental cost for Move-in-Truckers = 70 + 0.12m

Plug in the value of x = 47

= 70 + 0.12(47) = $75.64 ≈ $76

Estimate how many 12 inch rulers will be about the same length as a bike

navik [9.2K]

Answer:

So that means length of the bike is approx 5.7 rulers.

Step-by-step explanation:

the question says to estimate how many 12-inch rulers will be about the same length as a bike. In other words we have to measure the length of bike by in terms of ruler like 3 ruler length or 5 rular length etc.

Type of bike is not mentioned so i'm going to use bicyle.

From internet I found that approx lenght of a bike ( bicycle) is = 68 inches.

Given that 1 ruler = 12 inches

So number of rulers that can fit into 68 inches can be found by dividing 68 by 12

68/12 = 5.7

A cube has side length a. The side lengths are decreased to 50% of their original size. Write an expression in simplest form for

vaieri [72.5K]

Answer:

V = a³/8

Step-by-step explanation:

The volume of the original cube is the cube of the side length:

V = a³

When the side length is reduced to half its former value, the new volume is ...

V = (a/2)³ = a³/2³

V = a³/8 . . . . volume of the new cube

When plucked, the high E string on a guitar has a frequency of 330 cycles per second. What sine function represents this note wh

Ber [7]

Let's analyse the function

$y = f(x) = A\sin(\omega x)$

The amplitude is A, so we want A=1.5

Now, we start at x=0, and we have $1.5\sin(0)=0$

After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be $330\cdot 2\pi$

So, we have

$f(1)=1.5\sin(\omega) = 1.5\sin(660\pi)$

so, the function is

$f(x) = 1.5\sin(660\pi x)$
