On which surface is the student unable to apply enough force to overcome the force of friction
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.

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
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

H is the circumcenter, or point of concurrency, of the perpendicular bisectors of ΔACE.
Triangle A C E is shown. Point H is the circumcenter of the triangle. Lines are drawn from each point of the triangle to point H. Lines are drawn from point H to the sides of the triangle to form right angles. Line segments H B, H F, and H D are formed.
Which statements must be true regarding the diagram?
Answer:
∠HDC ≅ ∠HDE, AB ≅ BC, HC ≅ HE
Step-by-step explanation:
yup
The circumcenter describes the point of intersection of three perpendicular bisectors. Any point on the perpendicular bisector is equidistant from the endpoint of the segment. Hence, the true statements are :
HC ≈ HE∠HDC ≈ ∠HDEAB = BCThe intersection point H is equidistant from the vertices of the triangle A, C and E
Therefore, HA ≈ HC ≈ HE ; Hence, the expression ;
HC ≈ HEB is the midpoint of the line AC ; Hence, using the midpoint rule ; AB = BC
∠HDC ≈ ∠HDETherefore, only the three statements are true.

The sum of three consecutive number is 54
Find the first two
number.
a = 17
b = 18
c = 19
Step-by-step explanation:Hi there !
a + b + c = 54
b = a + 1
c = a + 2
replace b ; c
a + (a + 1) + (a + 2) = 54
3a = 54 - 3
3a = 51
a = 51 : 3
a = 17
b = 18

The perimeter of the square kitchen floor measures 48 feet what is the area of the kitchen floor
Answer:
the answer is 144 feet
Step-by-step explanation:
to find the how long each sides of the square is divide 48 by 4 (because that's how many sides there are on a square). by doing that you get 12
to find the area of the square you do A= lw which in this case it would look something like this:
A= 12(12) you use 12 twice because square sides are always equal
then you multiply which gives you A= 144

Mr. Bell wants to plant a rectangular garden in his backyard. He has 100 feet of fence to
enclose his garden. He wants the length to be 5 feet more than the width. What are the
dimensions, in feet, of the garden?
What is the total LENGTH in feet?
Answer:
The dimensions of the garden are 22.5ft by 27.5ft
Step-by-step explanation:
Here, we want to calculate the dimensions of the garden.
let the length be x ft
we are told that the he wants the length to be 5 feet more than the width;
That means the width will be (x-5) ft
Mathematically;
Since the shape is rectangular, the perimeter will be 2( l + w)
Thus; 2(x + x-5) = 100
2(2x-5) = 100
divide both sides by 2
2x-5 = 50
2x = 50 + 5
2x = 55
x = 55/2
x = 27.5 ft
The width is thus; 27.5ft - 5ft = 22.5ft
the dimensions of the garden are 27.5 ft by 22.5 ft

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)
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] #
Which value of n makes this equation true?
3n + 3/5 = 5n-1/9
A.
n=-16
B.
n=-2
c.
n= 2
D
n = 16
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.

Answer: y=2x-2
Step-by-step explanation: First you plot those two points and make a line, then find the rest below. Slope formula is y=mx+b. M is the slope, rise over run, which is 2, and b is the y-intercept, where it meets the y-axis, which is -2.
Which linear equation is best represented by the graph?
Answer:

Step-by-step explanation:
A linear equation is in the form of y=mx+b
You need to find the slope and y-intercept.
The slope is 2/3 Up 2, over 3 to the right.
The y-intercept is (0,-2)
So the equation would be, y=2/3x-2
