The correct option is (B).
What is mean by Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Now, From 0-4 the graph is uniformly increasing which represents 3 hours that's it's moving.
Then from 2-3 there no increment or decrement which represents it is in rest.
Then, from 4 - 5 the graph is uniformly increasing again which represents 1 more hours it is moving.
Hence, We get;
⇒ It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.

Mike makes a commission of 10% on each TV set sold at store. Each TV costs $120. How much
money will he make as commission if store sells 25 TV sets?
Answer:
$300
Step-by-step explanation:
10% = .1 and each TV costs 120 so .1*120=12 then you take 12*25 since 12 is the money he makes for seeling the tv multiplied by the total TV's sold and you get 300 so Mike makes $300
Answer:
300 just cross multiply to get the answer.

What is the measure of arc c?
190
95
120
70
Answer:
70°
Step-by-step explanation:
By inscribed angle theorem:
[tex] 95° = \frac{1}{2}(c + 120°)\\\\
\therefore 95°\times 2 = c + 120°\\\\
\therefore 190° = c + 120°\\\\
\therefore c = 190° - 120°\\\\
\huge \orange {\boxed {\therefore c = 70°}} [/tex]
How do you determine if polygons are similar?
Answer:
To find the scale factor, we simply create a ratio of the lengths of two corresponding sides of two polygons. If the ratio is the same for all corresponding sides, then this is called the scale factor and the polygons are similar.
Find the length of AM.
Answer:
AM = 26
Step-by-step explanation:
AM = MC
x+20 = 5x-4
Subtract x from each side
x+20-x = 5x-x-4
20 = 4x-4
Add 4 to each side
20+4 = 4x-4+4
24 = 4x
Divide by 4
24/4 = 4x/4
6 =x
We want AM
AM = x+20
=6+20
=26
Answer:
26
Step-by-step explanation:
x+20=5x-4
x+24=5x
24=4x
x=6
x+20
substitute 6 for x
6+20

Calculate the volume of the 3-D composite figure please!! show how you got the volume
Answer: 10,488 cu. in.
Step-by-step explanation:
Volume of rectangular prism = l x w x h
= 16 x 18 x 23 = 6624 cu. in
Volumr of triangular prism = 1/2bh (height of prism)
= 1/2 x 23 x 21 x 16
= 3864 cu. in.
Volume of the figure = 6624 + 3864 = 10,488 cu. in

Write the equation of a line that passes through (4,-10) and has a slope of 2, please!
Answer:
y = 2x - 18
Step-by-step explanation:
There are lots of different methods to do these types of questions, but this is the way i like to do it.
Coordinate (x1, y1) : (4, -10) and Gradient (m): 2
Start with this generic equation:
y- y1 = m(x-x1)
Substitute in the values they have given you:
y - (-10) = 2(x-4)
This becomes:
y + 10 = 2x - 8
Keep solving by moving the 10 over to the other side:
y = 2x -8-10
y = 2x - 18
An easy way to double check:
1) the coefficient of x is the slope. We got 2x, and the slope is 2, so that's correct.
2) Substitute x=4 into the equation, and we get -10, which is the exact coordinate that they gave us. This is also right.
Hope this helped : )
What is the slope of the line on the graph?
Answer:
2
Step-by-step explanation:
We can find the slope by
m = (y2-y1)/(x2-x1)
= (4-2)/(-1 - -2)
= (4-2)/( -1 +2)
=2/1
= 2
Answer:
2
Step-by-step explanation:
slope= [tex] \frac{y1 - y2}{x1 - x2} [/tex]
Thus, slope of the line
[tex] = \frac{4 - 2}{ - 1 - ( - 2)} \\ = \frac{2}{2 - 1} \\ = \frac{2}{1} \\ = 2[/tex]

5. How many real number solutions does the equation have?
0= -4x^2+7x+8
A) two solutions
B) one solution
C) no solutions
D) infinitely many solutions
6. How many real number solutions does the equation have?
0= 3x^2+18x+27
Answer:
5. A) two solutions
6. one solution
Step-by-step explanation:
5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:
b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number
When the discriminant is positive, there are two real solutions.
__
6. The equation factors as ...
0 = 3(x +3)^2
This will have one real solution at x=-3.
Simplify each expression. -21v^6/-6v^8
3.5/v^2
Step-by-step explanation:
-21v^6/-6v^8
-21/-6=3.5
v^6-v^8=-2
since -2 cannot be expressed as v^-2 it must be expressed as 1/v^2
so 3.5/v^2 is your answer
Answer:
7/2v^2

Find the probability of the outcome
Step-by-step explanation:
Total marbles = 2 + 4 +1 + 8 = 15 marbles
Probability of blue marble = 4 / 15
Probability of green marble = 2 / 15
Answer:
4/105
Step-by-step explanation:
Total number of marbles: 2 + 4 + 1 + 8 = 15
Number of blue marbles: 4
First drawing:
p(blue marble) = 4/15
Now there are 14 marbles left.
Number of green marbles: 2
p(green marble) = 2/14 = 1/7
p(blue then green) = p(blue) * p(green) = 4/15 * 1/7 = 4/105
Answer: 4/105
WILL MARK BRAINLIEST-30 PTS---On a coordinate plane, polygon GHIJ translates 8 units to the left to form polygon G'H'I'J'. Which of the following equations is not necessarily true?
A.
GH = G'H'
B.
G'G = 8 units
C.
m∠HIJ = m∠H'I'J'
D.
m∠HI'J = m∠H'IJ'
Answer:
The question is asking to choose among the following choices that states the equation that is not necessarily true about the said coordinate plane and in my further calculation, the answer would be G'H' = 8 units.
( I think you made a mistake when writing the answer choice for B, because the correct answer is G'H' = 8 units )

20. In the figures below, the cube-shaped box is 6 inches wide and the rectangular box is 10 inches long, 4 inches wide, and 4 inches high. How much
of the cube-shaped box than the rectangular box?
A. 50 cubic inches
B. 60 cubic inches
C. 66 cubic inches
D. 56 cubic inches
Answer:
56 cubic inches
Step-by-step explanation:
Volume of cube box = 6^3 = 6 *6*6 = 216 , Volume of rectangular box = 10*4*4 = 160 . Difference = 216 - 160 = 56 cubic inches. 56 cubic inches greater is the volume of the cube-shaped box than the rectangular box.
Answer:
Step-by-step explanation:
cube volume=side^3
given that the side is 6, the volume is 6^3 or 216 cubic inches
volume regular rectangular prism=length times width times height
given that length=10, width is 4 and height is 4, volume=10*4*4=160 cubic inches
how much greater
216-160=56
it is 56 cubic inches greater
this is ur answer buddy]
