Answer:
O Dependent: miles; Independent: gallons
Step-by-step explanation:
An independent variable is one which can stand alone. Its values is not affected(gets changed) by change in other variable.
Example : your age
value of your age will not change in other factor like how much you run, sleep etc.
A dependent variable is one which cannot stand alone. Its values gets affected(gets changed) by change in other variable.
Example : weight: weight of human is dependent on food you eat and hence more you eat more is the chance of weight being increased.
hence, weight is dependent variable.

Given
A car uses a gallon of gas for every 45 miles driven.
thus, there are two variable, which as identified is
miles and gallons
given that
in 1 gallon , car gets driven 45 miles
so if there are n gallons car will get driven 45*2 = 90 miles
in there are n gallons, car will get driven 45*n= 45n miles
hence , miles is dependent on no of gallons hence
miles is dependent variable.
thus, we see there is relationship between miles and gallon as
miles = 45n, where n is the no of gallons
here no of gallons is independent variable as its value can stand alone, its value does not change with miles.
hence
gallons is independent variable.
thus,
correct choice is
O Dependent: miles; Independent: gallons
While traveling across flat land, you notice a mountain directly in front of you. The angle of elevation to the peak is 1.5°. After you drive 23 miles closer to the mountain, the angle of elevation is 13°. Approximate the height of the mountain.
Answer:
0.68 miles
Step-by-step explanation:
Let's say that the height of the mountain is h
The distance between the mountain and the car, after moving 23 miles closer to the mountain, will be x (let's pose it as x for now)
tan(1.5°) = opposite/adjacent = h/23 + a
=> h = (23 + a)tan(1.5°) ---- (1)
tan(13°) = h/a
=> h = a(tan(13°)) ---- (2)
Now since h is common among the two equations, we can equate them;
[tex]\left(23+a\right)\tan \left(1.5^{\circ \:}\right)=a\left(\tan \left(13^{\circ \:}\right)\right),\\23\tan \left(1.5^{\circ \:}\right)+\tan \left(1.5^{\circ \:}\right)a=\tan \left(13^{\circ \:}\right)a,\\\\\tan \left(1.5^{\circ \:}\right)a-\tan \left(13^{\circ \:}\right)a=-23\tan \left(1.5^{\circ \:}\right),\\\left(\tan \left(1.5^{\circ \:}\right)-\tan \left(13^{\circ \:}\right)\right)a=-23\tan \left(1.5^{\circ \:}\right),\\\\[/tex]
[tex]a=\frac{23\tan \left(1.5^{\circ \:}\right)}{\tan \left(13^{\circ \:}\right)-\tan \left(1.5^{\circ \:}\right)} = 2.94249...[/tex]
[tex]h = 2.94249tan\left(13^{\circ }\right) = 0.67932\dots[/tex]
The height of the mountain ≈ 0.68 miles

What is the midpoint of -1.9 and 5.1 on a number line??!
Answer:
Add them and divide by 2. 5.1 + -1.9= 5.1 - 1.9, which is 3.2. 3.2 divided by 2 is 1.6. That is their midpoint on the number line(I can't plot it).

-2x<-2 and x-2<8
Answer:
x > 1, x < 10
Step-by-step explanation:
Part 1:
-2x < -2
Simplify (divide by -2)
x > 1-------------
Part 2:
x - 2 < 8
Simplify (add 2 to both sides)
x < 10
7x - 2(3x + 16) = -23
simplify the expression

Find the distance between the cities. Assume that Earth is a sphere of radius 4000 miles and that the cities are on the same longitude (one city is due north of the other). (Round answer to one decimal place.)
City Latitude
San Francisco, California 37° 47' 36" N
Seattle, Washington 47° 37' 18" N
_____Miles
The required distance between the two cities is 684.1 miles.
What is an arc?Arc is the measure of the angle on the circumference of a circle.
Length of an Arc = θ × (π/180) × r
Here,
San Francisco, California 37° 47' 36" N
Seattle, Washington 47° 37' 18" N
Differences in latitude,
Seattle, Washington 47° 37' 18" N
San Francisco, California -37° 47' 36" N
= 9° 49' 42"
Now converting all in degrees
Difference = 9° + 49 / 60 + 42/3600
Difference = 9 + 0.82 + 0.012
Difference = 9.832
Difference = 9.8°
Now,
the arc between two cities = 9.8 * π / 180 * 4000
= 684.1 miles
Thus, The required distance between the two cities is 684.1 miles.

What is the equation of the line that is perpendicular to y = -4x +5 and passes
through the point (4, -3)?
A.y=4x-19 B.y=-4+13 C.y=1/4x-4 D.y=-1/4x-2
Answer:
The answer is C, y = 1/4x - 4
Step-by-step explanation:
First, we have to find the slope of the perpendicular line, and to do so you must take the slope of the given line and opposite reciprocate it.
To do so, you first reciprocate the slope by flipping the numerator and denominator which now makes -4 into -1/4.
Then we have to make it the opposite value, like making a negative into a positive or a positive into a negative. In this case you make -1/4 into a positive 1/4.
We now have the slope of the perpendicular line and can make out answer choices A and B. Which now leaves us with C and D.
The line must go through the point (4, -3). To do that we must adjust the y-intercept until it goes though that point.
We get the y-intercept of -4 and the line that has the y-intercept of -4 and the slope of 1/4 is C.
You answer is C, y = 1/4x - 4.

[tex]d = 4\sqrt{2}[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(-4-0)^2+(-4-0)^2}[/tex]
[tex]d = \sqrt{(-4)^2+(-4)^2}[/tex]
[tex]d = \sqrt{16+16}[/tex]
[tex]d = \sqrt{32}[/tex]
[tex]d = 4\sqrt{2}[/tex]
