The slope of Helaine's line is 3
Explanations:Note that:
The slope - Intercept form of the equation of a line is:
y = mx + c
Where m = the slope
c = the intercept
The given equation is:
12x - 4y = 3
Rewrite the above equation in the form y = mx + c
4y = 12x - 3
Divide through by 4
[tex]\begin{gathered} \frac{4y}{4}=\frac{12x}{4}-\frac{3}{4} \\ \\ y\text{ = 3x - }\frac{3}{4} \end{gathered}[/tex]The slope, m = 3
The intercept, c = -3/4
Therefore, the slope of Helaines line is 3

5) Kendall is making a cone shaped party hats for his birthday. Then, each hatwill be filled with candy. The height on each cone is 7.5 inches and theradius is 1.5 inches. If she has 12 friends coming, how many cubic incheswill he need to fill all 12 hats with candy?
Explanation
In the question, we are given that,
[tex]\begin{gathered} height\text{ of cone = 7.5 inches} \\ radius\text{ of cone = 1.5 inches} \end{gathered}[/tex]We will need to find the volume of the cone.
[tex]volume\text{ of a cone =}\pi r^2h[/tex]Therefore, we will have;
[tex]V=\pi\times1.5^2\times7.5=53.0144[/tex]So for 12 hats with candy, we will have;
[tex]12\times V=12\times53.0144=636.1728[/tex]Answer: 636.1728 cubic inches
Finds the measures of angle b and d given that m ll n. Explain.
Answer:
b = 60.7
d = 43.1
Explanation:
The angles of measure 60.7 and b are alternate interior angles because they are on opposite sides of the transversal and in the inside of the parallel lines m and n. These angles have the same measure, so
b = 60.7
Angle d and the angle of measure 136.9 form a straight line, so they sum to 180 degrees. Therefore, the measure of angle d is
d = 180 - 136.9 = 43.1
Therefore, the answers are
b = 60.7
d = 43.1

According to the diagram, we get the following equations:
Equation 1:
[tex]m\angle1\text{ + m}\angle2=180^{\circ}[/tex]Equation 2:
[tex]m\angle4\text{ + m}\angle3=180^{\circ}[/tex]the angle 3 is 112 degrees, so replacing this value into the previous equation, we get:

[tex]m\angle4\text{ }=180^{\circ}-112^{\circ}=68^{\circ}[/tex]now, note that
Equation 3:
[tex]m\angle4\text{ + m}\angle1=180^{\circ}[/tex]but the angle 4 is 68 degrees, so replacing this into the above equation, we get:
[tex]68^{\circ}\text{ + m}\angle1=180^{\circ}[/tex]solving for angle 1, we get :
[tex]\text{ m}\angle1=180^{\circ}-68^{\circ}=112^{\circ}[/tex]Finally, from equation 1, we get:
[tex]112^{\circ}\text{ + m}\angle2=180^{\circ}[/tex]then,
[tex]\text{ m}\angle2=180^{\circ}-112^{\circ}=68^{\circ}[/tex]we can conclude that the correct answer is:

Peanuts are sold in 8 ounce and 12 ounce packages. what is the fewest number of ounces you can buy of each package to have equal amounts of each package size
The lowest common denominator is defined as the set of fraction denominators with the lowest common multiple. The lowest positive integer with more than one denominator in the set is LCD.
Given that the Peanuts are sold in 8-ounce and 12-ounce packages
We have to determine the number of ounces you can buy from each package to have equal amounts of each package size
8 = 2 × 2 × 2
12 = 2 × 2 × 3
The LCDs 8 and 12 are 24
Thus, three 8 oz packets and two 12 oz packets.
Therefore, you can buy from each package to have equal amounts of each package size the number o ounces as 3 packets of 8 ounces and 2 packets of 12 ounces.
A 40 kilogram bag of seeds are spread out throughout the entire yard, how much in kilograms of seeds will not be watered? Percentage of my previous question is 96.1%In the last question 96.1% of grass was covered in water Their were 123 squares that got water except 5 of them so I divided 123 by 128 to find the percentage of grass covered by waterIf their were 5 squares that didn’t get water out of 128 then can’t we work from that? To find the 40 kilograms that wouldn’t get water from those 5 squares
5 squares of 128 didn't get water.

[tex]undefined[/tex]Drag the red and blue dots along the x-axis and y-axis to graph 7x+3y=127x+3y=12
Answer:
Explanation:
A linear equation can be graphed in a simple manner. We just have to find two points that lie on the line of the equation and then connect them to produce a line.
Now what two points lie on 7x + 3y = 12?
Well, let us pick a point where x = 0. What is the y-coordinate? Putting x = 0 into our equation gives
[tex]\begin{gathered} 7(0)+3y=12 \\ 3y=12 \end{gathered}[/tex]diving both sides by 3 gives
[tex]\begin{gathered} y=12/3 \\ y=4 \end{gathered}[/tex]Hence a point with x = 0, y= 4 lies on the line. In other words, (0, 4) lies on the line.
We now need to find a second point that lies on the line. How about

[tex]3.77\times10^7[/tex]Lincoln went into a movie theater and bought 2 bags of popcorn and 4 candies, costing a total of $34. Zoey went into the same movie theater and bought 6 bags of popcorn and 5 candies, costing a total of $74. Determine the price of each bag of popcorn and the price of each candy.
12 each bags
Step-by-step explanation:
2x +4y =34
6x +5y =74
x =34- 4y ÷2
y = $3
x= $ 11
bag each price is $11
The price of one bag of popcorn is $9 and the price of one candy is $4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Let the price of 1 bag of popcorn = x
And price of 1 candy = y
Given that,
Lincoln buys 2 bags of popcorn and 4 candies for $34
implies that,
2x + 4y = 34 (1)
Also, Zoey buys 6 bags of popcorn and 5 candies for $74
implies that,
6x + 5y = 74 (2)
By solving equation (1) and (2),
x = 9 and y = 4
The price of one bag of popcorn is $9 and the price of one candy is $4.

Tom buys some shirts for $15 each. He has a coupon for $9 dollars off the total price. If he pays $36, how many shirts, s , did he buy
We have to find how many shirts (s) he has bought.
We know that each shirt costs $15, so the total cost of the shirts should be 15*s.
If we substract the discount, we have the total final cost C as:
[tex]C=15\cdot s-9[/tex]If we know that this total cost was $36, we can find the number of shirts as:
[tex]\begin{gathered} C=36 \\ 15s-9=36 \\ 15s=36+9 \\ 15s=45 \\ s=\frac{45}{15} \\ s=3 \end{gathered}[/tex]Answer: He bought 3 shirts (s = 3).

I know that the equation is 5/9 (x-1) squared -3 What is the y-coordinate for the point where the parabola intersects the x-axis?
Answer:
-22/9
Explanation:
If the equation of the parabola is
y = 5/9 (x - 1)² - 3
The y-coordinate for the point where the parabola intersects the x-axis can be calculated by replacing x = 0, so
y = 5/9 (0 - 1)² - 3
y = 5/9 (-1)² - 3
y = 5/9 (1) - 3
y = 5/9 - 3
y = -22/9
Therefore, the y-coordinate is -22/9
Melissa is choosing between two exercise routines,In Routine #1, she burns 42 calories walking. She then runs at a rate that burns 14.25 calories per minute.In Routine #2, she burns 25 calories walking. She then runs at a rate that burns 18.5 calories per minute.For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #27Use t for the number of minutes spent running, and solve your inequality for t.
Suppose in routine 1 and 2, Melissa rune for t minutes.
She burns 42 calories walking and then she runs at a rate that burns 14.25 calories per minute in rouitne 1.
So, total calories she burns in routine 1 is

Which of the following is a function?(A)(B)(C)(D) {(-5,9), (-2,-5),(1,-5),(5,-2)} (E){(-5,9),(-2,-5),(1,-5).(-5,-2)}
Explanation:
A relation is a function if and only if there is one value of x for different values of y.
This means that if we see repeated x-values then it's not a function. We can see this clearly in the graphs by drawing a vertical line for the values of x. Of the line crosses the graph more than once, then it's not a function.
In every graph the line crosses the graph more than once, so none of these options are functions.
Then, for a set of points we have to check the x-coordinate of each pair. If one repeats in the set, then it's not a function.
In the relation E x = -5 is repeated, so it's not a function. On the other hand, for relation D none of the x-coordinates are repeated. Therefore relation D IS a function
Answer:
Option D is a function

Using the normal distribution, it is found that, the standard deviation is 0.86
What does "normal" describe in statistics?Normal usually refers to the word "normal" in a normal distribution.
The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from the mean, its chances decrease.
In a normal distribution with mean μ and standard deviation σ, the z-score of a measure X is;
σ = √np(1- p)
After finding the z-score, we need the p-value associated with this z-score, which is the percentile of X.
The given parameters are:
n = 3 ---- the number of flips
p = 0.5 --- the probability
The standard deviation is calculated as:
σ = √np(1- p)
σ = √3 (0.5) (0.5)
σ = 0.86
Hence, the standard deviation is 0.86
