The function w=30-3/4n represents the weight w in pounds of the papers in tyrones newspaper delivery bag after he delivers n newspapers. Find the zero and explain what it means in the context of this situation. Find the domain and range
Answer:
domain (−∞,∞)
range (−∞,∞)
n = 40 and it refers to the fact that after delivering 40 newspapers, there will be no paper left in the bag
Step-by-step explanation:
To find the zero, we equate the linear equation to zero
w = 30 - 3n/4
3n/4 = 30
3n = 120
n = 120/3
n = 40
What this mean in this context is that the the bag becomes empty after he has delivered 40 newspapers or we can say that the maximum number of papers the bag can take is 40
The range refers to the number on the y-axis
Here the range is (−∞,∞)
The domain refers to the x axis values
We have (−∞,∞)
Substitute the given values into the formula, and solve for the unknown variable.

Answer:
Lines J, K, and M are all parallel to each other.
Step-by-step explanation:
Parallel lines are two or more lines that are on the same plane but never intersect. Because they don't intersect they the same distance apart no matter what point you measure from on the line. Line N is the transversal for lines J, K, and M.

In Exercises 1 and 2, find the coordinates of point Q along the directed line segment LM so that LQ to QM is the given ratio. 1. L(-1, -2), M(3, 6); 5 to 3
Answer:
The coordinates of Q are (1.5,3)
Step-by-step explanation:
Here, we simply want to divide the line segment in the given ratio
We can use the internal division formula here;
The coordinates of Q will be;
(x,y) = (nx1 + mx2)/(n + m) , (ny1 + my2)/(n + m)
m = 5, n = 3
(x,y) = (3(-1) + 5(3))/(5 + 3) , (3(-2) + 5(6)/(5 + 3))
(x,y) = (-3 + 15)/8 , (-6 + 30)/8
(x,y) = 12/8, 24/8
(x,y) = (1.5,3)

Step-by-step explanation:
Teri invested $2500 in an account with an interest rate of 2.75% compounded continuously. How
long will it take for Teri's account to earn $6000?
The time it will take for Teri's account to earn $6000 = 87 years
The total amount of money invested by Teri ( p) = $2500
The interest rate of the investment (r) = 2.75%
The simple interest is ( I) = $6000
Therefore the time to generate the interest of $6000
[tex] \frac{i \times 100}{p \times r \: } = t[/tex]
Therefore, time =
[tex] \frac{6000 \times 100}{2500 \times 2.75} [/tex]
[tex] \frac{600000}{6875} [/tex]
=87 years.
Therefore, the time it will take for Teri's account to earn $6000 = 87 years

According to the graph, what is the experimental probability of selecting the letter T?
1/20
4
1/4
1/5
Answer: the answer is 1/5 I put 4 and got it wrong, after submitting the test it showed me the answer
Experimental probabilities are based on the results of an experiment.
The experimental probability of T is (d) 1/5
From the graph, we have:
[tex]\mathbf{M = 6}[/tex]
[tex]\mathbf{A = 3}[/tex]
[tex]\mathbf{T = 4}[/tex]
[tex]\mathbf{H = 7}[/tex]
So, the experimental probability of T is:
[tex]\mathbf{P(T) = \frac{T}{M + A + T + H}}[/tex]
This gives
[tex]\mathbf{P(T) = \frac{4}{6 + 3 + 4 + 7}}[/tex]
[tex]\mathbf{P(T) = \frac{4}{20}}[/tex]
Simplify
[tex]\mathbf{P(T) = \frac{1}{5}}[/tex]
Hence, the experimental probability of T is (d) 1/5

Answer:
A. x=8 y=21
Step-by-step explanation:
line l and line m are parallel, and both angles that have x in the values are on the same side, so they are equal to each other.
7x+12=12x-28
+28 +28
7x+40=12x
-7x -7x
40=5x
/5 /5
8=x
Since A is the only choice that has x=8, it must be the right answer.
Answer:
x = 8, y = 21
Step-by-step explanation:
parallel means they're equal so..
7x + 12 = 12x - 28
-7x -7x
12 = 5x -28
+28 +28
40 = 5x
8 = x
plug in 8 to 12x - 28
12(8) - 28
96 - 28 = 68
180 - 68 = 112
9y - 77 = 112
+77 +77
9y = 189
y = 21

Carlo and Helen spend the same amount of money on art supplies. Carlo buys 4 glue sticks and spends $3 on glitter. Helen buys 2 glue sticks, and she spends $3.75 on tape and $2.75 on paint. What is the cost, x, of each glue stick
Answer:
1.75
Step-by-step explanation:
none try your best
The cost of each glue stick is $1.75 if Carlo and Helen spend the same amount of money on art supplies.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Carlo and Helen spend the same amount of money on art supplies.
Let the cost of each glue stick is x
Carlo spent: 4x + 3
Helen spent: 2x + 3.75 + 2.75
4x + 3 = 2x + 3.75 + 2.75
2x = 6.5 - 3
2x = 3.5
x = 3.5/2
x = $1.75
Thus, the cost of each glue stick is $1.75 if Carlo and Helen spend the same amount of money on art supplies.

A city planner uses a coordinate grid to model the streets of a city. Each unit on the coordinate grid represents one city block. City hall is located at (0,0).The downtown area is represented by rectangleABCD, which has the vertices listed below. A(9,9) B(9,−2) C(−8,−2) D(−8,9) What is the perimeter of the downtown area?
Answer:
The perimeter of the downtown area is 56 units.
Step-by-step explanation:
From Geometry we know that perimeter ([tex]p[/tex]), dimensionless, is the sum of the lengths of the rectangle, that is, its 4 sides:
[tex]p = AB + BC + CD + DA[/tex] (1)
Where [tex]AB[/tex], [tex]BC[/tex], [tex]CD[/tex] and [tex]DA[/tex] are the sides of the rectangle, dimensionless.
Each side length is determined by Pythagorean Theorem:
[tex]AB = \sqrt{(9-9)^{2}+(-2-9)^{2}}[/tex]
[tex]AB = 11[/tex]
[tex]BC = \sqrt{(-8-9)^{2}+[-2-(-2)]^{2}}[/tex]
[tex]BC = 17[/tex]
[tex]CD = \sqrt{[-8-(-8)]^{2}+[9-(-2)]^{2}}[/tex]
[tex]CD = 11[/tex]
[tex]DA = \sqrt{[9-(-8)]^{2}+(9-9)^{2}}[/tex]
[tex]DA = 17[/tex]
Then, the perimeter of the downtown area is:
[tex]p = 11+17+11+17[/tex]
[tex]p = 56[/tex]
The perimeter of the downtown area is 56 units.

Find the equation of OP.
The required equation of a circle P is x² + (y −3)² = 4. The correct answer is option (F).
As per the shown figure, the circle P with a center at (0, 3) and a radius is 2 units.
The center of the circle is given as (h,k) = (0, 3)
So the equation of the circle is:
⇒ r² = (x − h)² + (y − k)²
Substitute the values of r, h, and k in the above equation,
⇒ 2² = (x − 0)² + (y −3)²
⇒ 4 = x² + (y −3)²
⇒ x² + (y −3)² = 4
Hence, the equation of a circle P is x² + (y −3)² = 4.
