Explain your reasoning
B. What does the point (3,90) represent in the context of this situation?
C. Based on the graph, how many dollars will Mr. David earn if he works
10 hours? Show or explain how you got your answer.
D. Write an equation that could be used to find y, the number of dollars
Mr. David earns for working x hours.
Answers
Answer:
A. Proportional by $30
B. 3 represents the hours he works
90 represents the money he earned
C. $300
D. I don know, sorry
Step-by-step explanation:
The relationship is linear, the point (3, 90) represents in 3 hours he earns 90 dollars, in 10 hours, he earns 300 dollars, and the linear equation is y = 30x.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
This graph shows the relationship between x, the number of hours Mr. David works, and y, the number of dollars he earns.
A. Based on the graph, the relationship between x and y proportional is a linear relationship.
B. The point (3,90) represents in 3 hours he earns 90 dollars.
D. The linear equation will be
[tex]\begin{aligned} \rm y - 30 &= \rm \dfrac{90-30}{3-1} (x - 1)\\\\\rm y - 30 &= \rm 30x - 30\\\\\rm y &= \rm 30x \end{aligned}[/tex]
C. Based on the graph, the amount of money in dollars will Mr. David earn if he works 10 hours will be
y = 30x
y = 30 × 10
y = $300

What are the ratios for SIN A and COS A
Answers
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=Opposite over Hypotenuse
Cos=Adjacent over Hypotenuse
Tan=Opposite over Adjacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].

with slope –1/4, passing through (-4, -1)
Answers
Answer:
[tex]y = -\frac{1}{4}x - 2[/tex]
Step-by-step explanation:
i'm not sure if you're trying to find the equation of the line ?? but i'll assume that's the case and find the slope-intercept form equation of the line.
slope intercept form is [tex]y = mx + b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept. since the slope is already identified, you can plug in [tex]-\frac{1}{4}[/tex] for [tex]m[/tex].
[tex]y = mx + b[/tex] ⇒ [tex]y = -\frac{1}{4}x+b[/tex]plug in the [tex]x[/tex] and [tex]y[/tex] values from the coordinate pair that passes through the line, which is (-4, -1). you can start with either [tex]x[/tex] or [tex]y[/tex], but i'm going to start with [tex]x[/tex].
first, plug in [tex]-4[/tex] for [tex]x[/tex].
[tex]y = -\frac{1}{4}x+b[/tex] ⇒ [tex]y = -\frac{1}{4}(-4)+b[/tex]now plug in [tex]-1[/tex] for [tex]y[/tex].
[tex]y = -\frac{1}{4}(-4)+b[/tex] ⇒ [tex]-1 = -\frac{1}{4}(-4)+b[/tex]after plugging in all of the given values, the equation is now [tex]-1 = -\frac{1}{4}(-4)+b[/tex], in which you need to solve for [tex]b[/tex].
now it's time to solve! begin by multiplying [tex]-\frac{1}{4}(-4)[/tex] in order to simplify the right side of the equation.
[tex]-\frac{1}{4}(-4) = 1[/tex]you now have [tex]-1 = 1 + b[/tex]. subtract 1 from both sides of the equation. on the right side, it cancels itself out, leaving you with [tex]b[/tex]. on the left side of the equation, you now have [tex]-1 - 1[/tex], which equals [tex]-2[/tex].
therefore [tex]-2 = b[/tex], or [tex]b = -2[/tex].
now that you've solved for your [tex]b[/tex] value, plug it into your initial slope-intercept form equation!
[tex]y = -\frac{1}{4}x + b[/tex] ⇒ [tex]y = -\frac{1}{4}x - 2[/tex]if you want to check to make sure that the values are correct, plug (-4, -1) into your completed slope-intercept form equation. as you did in the beginning, plug in [tex]-4[/tex] for [tex]x[/tex] and [tex]-1[/tex] for [tex]y[/tex].
[tex]y = -\frac{1}{4}x - 2[/tex] ⇒ [tex]-1 = -\frac{1}{4}(-4) - 2[/tex]begin simplifying by multiplying [tex]-\frac{1}{4}(-4)[/tex].
[tex]-1 = -\frac{1}{4}(-4) - 2[/tex] ⇒ [tex]-1 = 1 - 2[/tex]subtract [tex]1 - 2[/tex].
[tex]-1 = 1 - 2[/tex] ⇒ [tex]-1 = -1[/tex]since both sides of the equation are equal, that means your [tex]b[/tex] value of [tex]-2[/tex] is correct because it makes the equation true!

Answers
Answer:
40
Step-by-step explanation:
Cost of the bottles of water = $0.75
Sales of the bottle= $1.05
markup Price= [(Sales of the bottle)-(Cost of the bottles of water)]/Cost of the bottles of water
= ($1.05- $0.75)/$0.75

There are 7 ted marbles. 7 blue marbles, and 7 green marbles.If a person randomly selects 1 marble from the bag, what is the probability that the person selects a blue marble.
Answers
Answer:
there are an equal amount of all three colors of marbles in the bag, so the probability of selecting a blue marble is just 1/3.
Let me know if this helps!
There is 21 marbles and if you divided by 3 it gets 7.
7/21 is equal to 1/3
Therefore the possibility of picking a blue marble is 1/3.

An employee at a company that assembles chandeliers is packing boxes
for shipping. In the first box, he packed 3 small chandeliers and 4 large
chandeliers, which weighed a total of 122 kilograms. In the second box,
he packed 3 small chandeliers and 2 large chandeliers, which had a
weight of 76 kilograms. Assuming the weight of the box isn't included in
the shipping weight, how much does each size of chandelier weigh? *
Answers
Answer:
Each Large chandelier weighs 23 kilograms (fat chandelier) and each small chandelier weighs 10 kilograms.
Step-by-step explanation:
I found this by subtracting the 122 from the 76 which gave me a 46 difference I then divided it by 2 since they took away 2 large chandeliers which gave me 23. I then multiplied 23 by 4 which gave me 92 and I saw that to get to 122 I would need 30 kilograms so I divided the 30 by the 3 small chandeliers.

complimentary angles equal 90 degrees so 1 and 2, 3 and 4, 9 and 10, 11 and 12 would be complimentary
supplementary angles equal 180 degrees so 6 and 5, 5 and 7, 7 and 8, and 8 and 6 would be supplementary
First, a complementary angle are two angles that add up to 90. while supplementary add up to 180.
Complementary angles; 1 & 2, 3 & 4, 9 & 10, 11 & 12. (these all make one line which equals 180.)
Supplementary angles; 7 & 8, 5 & 7, 6 & 5, 8 & 6. (these all make up a 90 degree angle.)
