I need help with this, please. Your family is driving from Harrisburg Pennsylvania to San Antonio, Texas a trip of 1430 miles. Y
olga_2 [115]

Estimate the total amount you should plan to spend on gasoline for the entire trip

<em>Total distance of the trip</em> = 1430 miles

<em>After 350 miles, refill tank</em> = $35

This means 350 miles cost $35

1430 miles cost $x

solve using ratio

350 : 35 = 1430 : x

350/35 = 1430 / x

10 = 1430/x

<em>cross product</em>

10x = 1430

<em>Divide both sides by 10</em>

x = 1430 / 10

x = $143

Therefore, the total amount you should plan to spend on gasoline for the entire trip is $143

larry earned $11 walking his neighbors' dogs on saturday. he earned some extra money on sunday doing the same thing. write an ex
jok3333 [9.3K]
This is easy. He first earned $11 on Saturday and then on Sunday he earned some money. We don't know how much he earned, we just know he earned some money. Let's put the expression together. A good place to start would be the $11. Let's add eleven to the expression. And because he earned some more money, it's going to be addition. So currently, the expression stands at $11 + 
And because we don't know how much money he made on Sunday, x will be the variable for how much he earned. So the expression will be 

11 + x

The ubiquitous 12oz aluminum cans used to distribute drinks in this country have a diameter of approximately 2.75 inches and a h
gayaneshka [121]

Answer:

3.5%

Step-by-step explanation:

The volume of a cylinder = \pi r^2h

<em>r</em> = radius of cylinder,

<em>h</em> = height of cylinder

For the non-optimal can,

<em>r</em> = 2.75/2 = 1.375

<em>h</em> = 5.0

V = \pi(1.375^2)\times 5.0 = 9.453125\pi

<em />

For the optimal can,

<em>d</em>/<em>h</em> = 1,

<em>d</em> = <em>h</em>

2<em>r </em>=<em> h</em>

<em>r</em> = h/2

V = \pi\left(\dfrac{h}{2}\right)^2\times h = \pi\left(\dfrac{h^3}{4}\right)

They have the same volume.

<em />\pi\dfrac{h^3}{4} = 9.453125\pi<em />

h^3 = 37.8125

h=3.36 (This is the height of the optimal can)

r = \dfrac{3.36}{2} = 1.68 (This is the radius of the optimal can)

The area of a cylinder is

<em />A = 2\pi r(r+h)<em />

For the non-optimal can,

A = 2\pi\times\dfrac{2.75}{2}\left(\dfrac{2.75}{2}+5.0\right) = 17.53125\pi

For the optimal can,

A = 2\pi\times1.68\left(1.68+3.36\right) = 16.9344\pi

Amount of aluminum saved, as a percentage of the amount used to make the optimal cans = \dfrac{17.53125\pi - 16.9344\pi}{16.9344\pi}\times 100\% = 3.5\%

What is the slope of the line represented by the equation y = -x-3?
wariber [46]

Answer:

(C) 1/3

Step-by-step explanation:

The slope intercept form: y = mx + b.

Note:

m = slope

b = y-intercept

x & y = (x , y) for the points.

You are trying to get the y-intercept of the following function given:

f(x) or y = (-2/9)x + (1/3)

1/3 is your answer, or (C), for 1/3 replaces the <em>b</em> inside the equation.

If you really need the slope, the slope of the following equation is (-2/9), which replaces the <em>m</em> inside the equation.
