Answer:
2.5x + 20 = y
Step-by-step explanation:
first, assign a variable to each unknown:
since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y
x = number of videos rented
y = total cost
so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.
So, the equation is 2.5x + 20 = y

18% discount on a list price of $25
Answer:
$20.50
Step-by-step explanation:
100% price - 18% discount = 82%.
82% can be written as .82
The original price was 25, so we multiply 25 by 0.82. We get $20.50.
If you are looking for the amount saved, subtract 20.5 from 25. We get $4.50.
There is a bag filled with 4 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 red?
Answer:
im not sure but this is just a guess (please keep it in mind)
Step-by-step explanation:
4+5= 9 marbles all together
9-1= 8
1 in 8? or 1 in 9
this is becuase we dont know if the one that was taken out randomly first wasnt a red or not but then i could be wrong and the fact if it was red or blue in the first place might not even matter. it really depends.

Find the area of the composite figure?
Answer:
128
Step-by-step explanation:
Let's start by figuring out the last side of the triangle
we can use the pathagoryous theroem and get
11.9²+x²=16.9²
Solve this and get x=12
Let's now compute the area of the triangle
b*h*.5
12*11.9*.5=71.4
So 71.4 is the area of the triangle
we now need to find the area of the semi circle.
to do this we are going to find the area and then divide it by 2
We know that the length is equal to 12 which means that the radius is 6
so we have
π6²/2
which is 56.55
We add the 71.4+56.55= 127.94 which rounds to 128
Answer:
212.758
Step-by-step explanation:
Find the semi-circle first, the diameter is 16.9 ft.
To find area:
Formula:
pi x radius x radius x 1/2
16.9 ÷ 2 = 8.45 (radius)
22/7 x 8.45 x 8.45 = 224.407 (Circle)
224.407 ÷ 2 = 112.203 (Semi circle)
Find the triangle:
1/2 x base x height or length x base x height
But for now, we will use the first one.
1/2 x 16.9 x 11.9 = 100.555
Now add them up.
100.555 + 112.203 = 212.758

Answer:
-3/2
Step-by-step explanation:
Parallel lines have same slopes.
please help me will give you brainliest!!
Answer:
yes, no, no, yes
Step-by-step explanation:
Plug in each point into both equations to see which ones fit.
For the first point, (4,1) it works for both equations.
1=-2( 4 ) + 9, 1= -8 + 9, 1=1
4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18
Do it for the rest of the points and plug them in and you get,
no for (5,-3) because -1 does not equal to -3
no for (6,0) because -3 does not equal to 0
(-5,19) is yes because 19=19 and 18=18

The length (JL) of the right-angle triangle will be 1.732 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
In the right triangle shown, angle ∠K = 60° and KL is 2. Then the measure of the length JL will be given by the sine the angle ∠K. Then the equation is given as,
JL / KL = sin ∠K
h / 2 = sin 60°
h / 2 = √3 / 2
h = √3
h = 1.732 units
The length (JL) of the right-angle triangle will be 1.732 units.

A. 3
B. 2
C. 1
D. 0
The total number of common tangents that can be drawn to the circles is 3 Hence, the correct option is (A).
What is tangent?The tangent is a line that goes by touching the circle.
If we meet that point to the circle then it gives us 90 degrees.
Given that the circle are intersecting so a common tangent will be
The First will be at the intersection point of that circle.
The second will be the upper portion of the circle.
The third will be the lower portion of the circle.

building. Mark realizes that when he looks up from the ground.
60 m away from the flagpole, that the top of the flagpole and the
top of the building line up. If the flagpole is 35m tall, and it is
310 m from the building, how tall is the building? Explain your
answer. On your answer sheet.copy the diagrams and label all
parts)
Answer:
Step-by-step explanation:
Let h bet the height of the building.
Mark is 60+310 = 370 m from building.
35/60 = h/370
h = 1295/6 = 215⅚ meters

Replace x with any number and solve for Y.
Do this at least twice to get 2 points.
Place these points on the graph and draw a line through them.
See attached graph.
Let x = 2
y = 1.4(2)
y = 2.8
First point = (2,2.8)
Let x = 5
y = 1.4(5)
y = 7
Second point = (5,7)
The y-intercept is zero, that means the line is passing through origin.
What is the equation of line?The equation of line is given as
y = mx + c
Where m is the slope and c is the y-intercept.
The equation is given below.
y = 1.4x
In the above equation, y-intercept is not there, which means the line is passing through origin.

The midpoint of \overline{\text{AB}} AB is M(5, 1)M(5,1). If the coordinates of AA are (3, 6)(3,6), what are the coordinates of BB?
Answer:
(7, -4)
Step-by-step explanation:
The formula for calculating midpoint is expressed as;
M(X, Y) = (x2+x1)/2, (y1+y2)/2
X = x1+x2/2
Y = y1+y2/2
Given
X = 5, Y = 1, x1 = 3, y1 = 6
Get x2
X = x1+x2/2
5 = 3+x2/2
10 = 3+x2
x2 = 10-3
x2 = 7
Get y2;
Y = y1+y2/2
1 = 6+y2/2
2 = 6+y2
y2 = 2-6
y2 = -4
Hence the coordinate of B is at (7, -4)
