Step-by-step explanation:
First we have to try all of the options to see if it is right
12.50(8)+20=120
(12.50*8)+20=120
100+20=120

What is the median of 5,2,9,21,12,3
Answer: 7
Step-by-step explanation:
First order the numbers by least to greatest
2, 3, 5, 9, 12, 21
Then find the number inbetween
In this case it's a tie between 5 and 9.
Find the average of those two numbers
The average is 5+9/2 = 7
Median is 7
Does the point (4, 1) lie on the line y = 3x + 1 ?
Answer:
no
Step-by-step explanation:
To determine if the point lies on the line, substitute x = 4 into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line.
y = 3(4) + 1 = 12 + 1 = 13 ≠ 1
Thus (4, 1) does not lie on the line
Replace x in the equation with the x value of the point and solve for y. If Y equals the y value of the point then the point lies on the line.
y = 3x + 1
y =3(4) +1 = 12 +1 = 13
y = 13, this does not equal the y value of the point which is 1, so point (4,1) does not lie on the line.
15.00 + 1.75x = 7.50 + 2.25
Carmena and Alicia go to the supply store to purchase packs of
pens and paper. Carmen bought 5 packs of paper and 3 packs
of pens for $36.60. Alicia bought 6 packd of paper and 6
packs of pens for $53.40. What is the price of one pack of
paper and one pack of pens?
Pens Are 4:95
Paper is 3:95
The prices for both the things are $4.95 and $3.95 respectively.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
Given that,
The price for 5 packs of paper and 3 packs of pens is $36.60.
And, for 6 packs of paper and 6 packs of pens is $53.40.
Suppose the price of one paper pack be x and of pens be y.
Then, the given case can be written in terms of equation as,
5x + 3y = 36.60 (1)
6x + 6y = 53.40 (2)
Solve the equations by multiplying equation (1) by 4 and (2) by 2 and then subtracting as follows,
2(6x + 6y) - 4(5x + 3y) = 2 × 53.40 - 4 × 36.60
=> 12x - 20x = 106.80 - 146.40
=> -8x = -39.60
=> x = 4.95
Substitute x = 4.95 in equation (2) to get,
6 × 4.95 + 6y = 53.40
=> 6y = 53.40 - 29.70
=> y = 23.70/6
= 3.95
Hence, the prices of one pack of paper and one pack of pens are $4.95 and $3.95 respectively.

Step-by-step explanation:
A garden is in a shape of an equilateral triangle with side 4 ft.
The objective is to find the area of the garden.
The formula to find the area of the triangle is, A= 1/2• b • h
Here, b represents the side of the triangle and h represents and h represents the height of the triangle.
The height of an equilateral triangle can be calculated by,
H = /3/2 • b
= /3/2 • 4
=
[tex] \sqrt[2]{3} [/tex]
Now substitute the value of b and h in the formula of area of triangle.
A = 1/2 • 4 •

from a point 12 ft from the base of a building, the angle of elevation from the ground to the top of the building is 70 degrees. Which is the closest to the height of the building
Answer:
c 33ft .....
Step-by-step explanation:
c is correct
The possible height of the building is 33 ft.
What is Angle of Elevation?
The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
Here, Let the height of the building be x ft
Base = 12ft.
Angle of Elevation = 70⁰
Now, tan α = perp. / base
tan 70⁰ = x/12
2.74 = x/12
x = 12 X 2.75
x = 33
Thus, the possible height of the building is 33 ft.

The original price of a bicycle was $375. Now it is on sale for $295. What percentage of the original price was the markdown?
Answer: $80
Step-by-step explanation:
Answer:
The percentage of the original price that was discounted is 21.33%
Step-by-step explanation:
The original price of a bicycle was $375. Now it is on sale for $295.
The discounted price of a product is calculated as the percentage of discount that you want to apply multiplied by the price of the product. This is the amount of money that is discounted. But to calculate the sale price, the original price of the product must be subtracted minus the discounted quantity.
So, this expressed in this case is:
375-x*375=295
The value of x is the discount that you want to calculate expressed in decimal number. This result will then be multiplied by 100 to obtain the discount expressed as a percentage.
Isolating the value of x you get:
-x*375=295-375
-x*375=-80
x=(-80)÷(-375)
x=0.2133
As a percentage, it is 0.2133*100= 21.33%
The percentage of the original price that was discounted is 21.33%

On a coordinate plane, a piecewise function has 3 lines. The first line has a closed circle at (negative 3, negative 4) and continues horizontally to an open circle at (0, negative 4). The second line has a closed circle at (0, 2) and continues horizontally to an open circle at (4, 2). The third line has a closed circle at (4, 3) and continues horizontally through (5, 3) with an arrow instead of an endpoint.

Answer:Answer:
f(-2) = 2
f(0) = 3
f (4) = -1
Step-by-step explanation:
The equation of the straight line passing through the points (0,3) and (-4,1) is
⇒ 2(y - 1) = x + 4
⇒ 2y - 2 = x + 4
⇒ 2y = x + 6
⇒
Again, the equation of the line passing through the points (0,1) and (4,-1) is
⇒ - 2 ( y + 1) = x - 4
⇒ - 2y = x - 2
⇒
Therefore, the function is defined as
for x ≤ 0 ........... (1) and
for x > 0 ............ (2)
Therefore, f(-2) = 2 from equation (1).
f(0) = 3 from equation (1)
And f (4) = -1 from equation (2). (Answer)

in the sequence: 67, 55, 46, 34, 25,…, what number should come next?
a) 16
b) 13
c) 15
d) 19
Answer:
b) 13
Step-by-step explanation:
67 - 55 = 12
55 - 46 = 9
46 - 34 = 12
34 - 25 = 9
25 - x = 12
rearrange that so,
25 - 12 = x
x = 13
Answer:
b) 13
Step-by-step explanation:
67 - 12 = 55
55 - 9 = 46
46 - 12 = 34
34 - 9 = 25
pattern: subtract 12, subtract 9
the pattern tells us to subtract 12, so take take 25 and subtract 12 from it:
25 - 12 = 13
