Answer:
(4,2)
Step-by-step explanation:
So proportional means that it is the same rate. I believe it is (4,2) because from 4 to eight is 4 and from 2 to 6 is also 4 and there for it is proportional.
Solve for y. 2(2y+6)=28
Answer:
y=4
Step-by-step explanation:
2(6 + 2y) = 28
(6 x 2 + 2y x 2) = 28
(12 + 4y) = 28
12 + 4y = 28
12 + -12 + 4y = 28 + -12
12 + -12 = 0
0 + 4y = 28 + -12
4y = 28 + -12
28 + -12 = 16
4y = 16
16\4
y = 4

Step-by-step explanation:
Joshua's goal is to sell more than 20 items at a farmers' market. So far, he has sold 6 items. Each customer buys 2 items. Let c represent the number of additional customers Joshua must have to meet his goal.
Drag and drop the answer into the box to correctly complete the statement:
Joshua needs to have more than ___ additional customers to meet his goal
additional customers to meet his goal.
A. 3
B. 7
C. 8
D. 14
Answer:
20-6= 14
14 divided by 2 equals 7
he needs 7 more customers
Step-by-step explanation:
have a wonderful day! brainliest?
Answer:
B. (7)
Step-by-step explanation:
First, we figure out how many more items Joshua needs to sell so we do 20 - 6.
20 - 6 = 14.
Next, we do 14 / 2 because each customer buys 2 items.
14 / 2 = 7
Therefore, Joshua must have 7 additional customers to reach his goal.

the area is 254.34 sq. ft.
Answer:
254.34 ft²
Step-by-step explanation:
diameter = 18 feet
radius = 18/2 = 9 feet
Area = pi x r²
= pi x 9²
= pi x 81
= 254.34 ft²

Find the measure of the angle
Answer:
27
Step-by-step explanation:
The triangle shown is an isoceles triangle. This means that there are two congruent base angles and a vertex angle. In this case, angle X and angle Y are the base angles, so we can set up an equation to first find the value of t.
5t - 13 = 3t + 3
2t - 13 = 3 (Subtract 3t from both sides)
2t = 16 (Add 13 to both sides)
t = 8 (Divide both sides by 2)
Now that we have the value of t, we can plug it back in to the expression for angle X to find its measure.
5(8) - 13
40 - 13
27
So, the measure of angle X is 27

Pls help math problem
Answer:
angle plm+angle lpm+angle pml=180°[by angle sum property]
21°+angle lpm+38°=180°
59°+ lpm=180°
lpm=180°-59°
lpm=121°
lpm+npl=180°[by limear pair]
121°+npl=180°
npl=180°-121°
npl=59°

f(x) = 8x - 1
Find f(-10) =
Answer:
-81
Step-by-step explanation:
f(x) = 8x -1
f(-10) = 8(-10) -1
f(-10) = -80-1
f(-10) = -81
Find the location of the center of a circle if the endpoints of the diameter are at (-10,
-5) and (8,4).
Answer:
(- 1, - [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
The centre is located at the midpoint of the diameter.
Using the midpoint formula , then
centre = [tex]\frac{-10+8}{2}[/tex], [tex]\frac{-5+4}{2}[/tex] ) = ( [tex]\frac{-2}{2}[/tex], [tex]\frac{-1}{2}[/tex] ) = (- 1, - [tex]\frac{1}{2}[/tex] )

Step-by-step explanation:
The daily advertising revenue (in dollars) for a local newspaper is given by the function R(t) = -18t2 + 720t – 103, where t is number of years that the paper has been in production. What is the daily advertising revenue after the paper has been in business for 15 years?
Answer:
6647
Step-by-step explanation:
The computation of the advertising revenue for 15 years is shown below:
Given that
r(t) = -18t^2 + 720t - 103
where
t = number of years = 15
now put the value of t in the above equation
= -18(15)^2 + 720(15) - 103
= -4050 + 10,800 - 103
= 6647

Are these proportional? And I need to show work sooo for example on the first question we did in class we wrote down
-3/1
-6/2=-3/1
-9/3=3/1
I hope I’m not asking for too much but I want to start off my trimester strongly.
Answer:
Step-by-step explanation:
If y is proportional to x,
y ∝ x
y = kx
k = [tex]\frac{y}{x}[/tex]
Here, k = Proportionality constant
For y = -8 and x = -4,
k = [tex]\frac{-8}{-4}[/tex]
k = 2
For y = -4 and x = -2
k = [tex]\frac{-4}{-2}[/tex]
k = 2
For all values of x and y proportionality constant = 2.
For x = 0 and y = 0,
If we graph a line passing through these points, the line will pass through the origin (No y-intercept).
And we know that any line passing through the origin represents the proportional relation between x and y variables.
Therefore, given table represents the proportional relation.

Find the area of the shaded region. Use 3.14 for pi.
Answer:
The shaded region is [tex]353.25m^2[/tex].
Step-by-step explanation:
The area of a circle is defined by the multiplication of the square of its radius, or half its diameter, by pi, or simply [tex]A=\pi r^2[/tex].
15m is the radius of the large circle, and also the diameter of the smaller circles.
The area of the shaded region will be the subtraction of the area of the two smaller circles from the area of the larger circle.
As such:
[tex]A=\pi(15)^{2}-2(\pi(\frac{15}{2} )^{2})\\\\A=(3.14)(15)^{2}-2(3.14)(\frac{15}{2} )^{2}\\A=706.5-353.25\\A=353.25[/tex]
Answer:
353.25 m²Step-by-step explanation:
Shaded region is the difference in the area of the bigger circle and two smaller circles.
Radius of bigger circle = 15 mRadius of smaller circles = 15/2 = 7.5 mThe shaded area:
A = π(15²) - 2π(7.5²) = π(225 - 112.5) = 3.14(112.5) = 353.25 m²URGENT!

Michael has $68. Craig has $24 less than Michael has. Michael spends $20 on a new hat. Michael has $68. Craig has $24 less than Michael has. Michael spends $20 on a new hat. Write an equation where the solution represents the amount of money (x), in dollars, craig has after michael buys the hat. Explain how you came to this equation.
Answer:
X + 4 = 48
Step-by-step explanation:
Before hat purchase :
Michael has $68
Craig has $24 less than Michael;
Hence, Craig = $68 - $24 = $44
Michael purchased hat worth, $20
x = amount Craig has after Michael purchase hat:
x = Amount Michael has - $24
Amount Michael has after hat purchase = $68 - $20 = $48
x + 4 = 44 + 4
X + 4 = 48

Calculate the area
Answer:
140 feet squared
Step-by-step explanation:
Let's do this step by step. First, let's find the area of the rectangle, which is 8 times 10. It equals 80. Next, do the trangle. 6 times 10 is 60. So, 60 plus 80 equals 140.
Answer:
area of rectangle =L*B
8*10=80ft^2
area of triangle=1/2b*h
h is 8 ft
1/2*6*8
3*8
24ft^2
total area is 80+24
104ft^2
nearest tenth = 100 ft^2
