A car uses a gallon of gas for every 45 miles driven. Identify the
independent and dependent variables of this situation.*
O Dependent: miles; Independent: gallons
O Dependent: gallons, Independent: miles
Dependent: miles, Independent: hours
O Dependent: cars, Independent: gallons
Answers
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

On which surface is the student unable to apply enough force to overcome the force of friction
Answers
Rough surfaces
Ex=carpet
The student unable to apply enough force to overcome the force of friction on rough surfaces.
What is Force?
A force is an influence that can change the motion of an object.
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
We need to find the type of surface the student unable to apply enough force to overcome the force of friction.
A rough surface will have more friction because on the rough surface there will be more irregularities.
So rough surface is the student unable to apply enough force to overcome the force of friction.
Hence, the student unable to apply enough force to overcome the force of friction on rough surfaces.

Answers
Answer: x2 + 34x - 13
Step-by-step explanation:
STEP
1
Trying to factor by splitting the middle term
1.1 Factoring x2+34x-13
The first term is, x2 its coefficient is 1 .
The middle term is, +34x its coefficient is 34 .
The last term, "the constant", is -13
Step-1 : Multiply the coefficient of the first term by the constant 1 • -13 = -13
Step-2 : Find two factors of -13 whose sum equals the coefficient of the middle term, which is 34 .
-13 + 1 = -12
-1 + 13 = 12
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
x2 + 34x - 13

What is an equation in slope intercept form of a line that passes through points (0,5) and (4,0)
Answers
Answer:
y = -5/4x + 5
Step-by-step explanation:
If you use rise/run it rises down 5 and runs to the right 4, therefore your slope is -5/4x and for your Y-intercept its 5 because (0,5) is already on the Y-axis, so your answer is y = -5/4x + 5
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ m=\frac{0-5}{4-0} \\m=\frac{-5}{4} \\m=-\frac{5}{4}[/tex]
Therefore the slope is m = -5/4
Find the equation
Let [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Substitute m = -5/4 in the equation,
[tex]y=-\frac{5}{4}x+b[/tex]
Substitute any ordered pairs that are given. I'll use (4,0) instead.
Substitute y = 0 and x = 4
[tex]0=-\frac{5}{4}(4)+b\\ 0=-5+b\\5=b\\[/tex]
Thus, the y-intercept is 5 (b is 5)
Therefore, the equation is [tex]y=-\frac{5}{4}x+5[/tex] #

Bob, Sally, and Billy Bob Joe are sharing jelly beans. Bob started with 77 jelly beans, Sally started with 12 jelly beans, and Billy Bob Joe started with 19 jelly beans. Bob gave 45 jelly beans to Sally. Sally gave 29 jelly beans to Billy Bob Joe, and Billy Bob Joe ate 30 jelly beans. How many jelly beans does Billy Bob Joe have left?
Answers
Answer:
Billy Bob Joe now has 18 jelly beans left
Step-by-step explanation:
Bob initially has 77 jelly beans, Sally initially has 12 jelly beans and Billy Bob Joe initially has 19 jelly beans.
If Bob gives 45 jelly beans to Sally, Bob now has 77 - 45 = 32 jelly beans and Sally now has 12 + 45 = 57 jelly beans.
Sally now gives 29 jelly beans to Billy Bob Joe. Sally now has 57 - 29 = 28 jelly beans and Billy Bob Joe now has 19 + 29 = 48 jelly beans.
If Billy Bob Joe now eats 30 jelly beans, he now has 48 - 30 = 18 jelly beans.
So, after eating 30 jelly beans, Billy Bob Joe now has 18 jelly beans left.

Once a month, volunteers from the Green Sea Club clean up litter at the beach. Last month, the volunteers picked up 8 pounds of trash in 4 hours. This month, the same group of volunteers will spend 3 hours picking up trash.
If they pick up trash at the same rate, how many pounds of trash should the volunteers pick up this month?
Answers
Answer:
Step-by-step explanation:
8 pounds.... 4hours
x pounds.... 3 hours
x=3 ×8 :4
x=24 :4
x=6 pounds of trash
The number of pounds of trash should the volunteers pick up this month is 6.
Calculation of the number of pounds:Since Last month, the volunteers picked up 8 pounds of trash in 4 hours. This month, the same group of volunteers will spend 3 hours picking up trash.
So here we can do
x=3 ×8 :4
x=24 :4
x=6
Hence, The number of pounds of trash should the volunteers pick up this month is 6.

6. Which of the following values are the zeroes of the expression 2x(x - 5)(x+7)?
(1) {-7,0,5)
(3) {-5, -2,7}
(2) {-7, -2,5)
(4) {-5,0,7}
Answers
Answer:
Step-by-step explanation:
To get the zeros of the expression 2x(x - 5)(x+7), we are going to equate the expression to zero and find the corresponding value of x as shown;
2x(x - 5)(x+7) = 0
2x = 0
x-5 = 0
x+7 = 0
From 2x = 0
x = 0/2
x = 0
From x-5 = 0
x = 0+5
x = 5
From the equation x+7 = 0
x = 0-7
x = -7
Hence the values of the zeros are {-7, 0, 5}

Answers
The value of n makes this equation true is -16.
How can we find the solution to an equation?We do same operations on both the sides so that equality of both expressions doesn't get disturbed. Solving equations generally means finding the values of the variables used in it for which the considered equation is true.
Sometimes we can find such value, and sometimes it is not possible at all, or sometimes, there are infinite number of solutions.
WE have been given an expression as;
3n + 3/5 = 5n-1/9
Combine the like terms;
3n + 3/5 = 5n-1/9
3n - 5n = -3/5 -1/9
-2n = -27 - 5 / 45
n = -16
The value of n makes this equation true is -16.

Suppose m∠3 = 128 and m∠6 = (10x + 8). What value of x would result in a || b?
A. 8.2
B. 4.4
C. 17.2
D. 12.0
Answers
Answer:
x = 12
Step-by-step explanation:
The attached figure shows the measures of the angles. Here, line a is parallel to line b.
Given that,
m∠3 = 128 and m∠6 = (10x + 8)
We need to find the value of x.
Here,
[tex]\angle 3 =\angle 6[/tex] (alternate interior angles)
So,
[tex]10x+8=128\\\\10x=128-8\\\\10x=120\\\\x=12[/tex]
So, the value of x is 12. Hence, the correct option is (D).
