Answer:
The Third Choice
Step-by-step explanation:
In this question, we have to compare the sine of angle A and the cosine of angle B. As a review, the sine function is
\(\text{sine} = \frac{\text{opposite}}{\text{hypotenuse}}\)
and the cosine function is
\(\text{cosine} = \frac{\text{adjacent}}{\text{hypotenuse}}\).
For angle A, side BC is the opposite side, while side AB is the hypotenuse. [The hypotenuse of a right triangle is the side that is opposite to the 90 degree angle. In this case, AB is the hypotenuse because it is opposite of angle C, which measures 90 degrees.]
Now, we can determine the sine of angle A.
\(\text{sine(A)} = \frac{\text{BC}}{\text{AB}} = \frac{4}{5}\).
For angle B, side BC is the adjacent side, while side AB is the hypotenuse.
Using this information, we can determine the cosine of angle B.
\(\text{cosine(B)} = \frac{\text{BC}}{\text{AB}} = \frac{4}{5}.\)
As we can see, both the sine of angle A and the cosine of angle B have the same value. In other words, they are equal to each other. Therefore, the correct answer is the third choice.

The event organizers are putting together two different types of treat bags. One type will contain a small container of bubbles and 1.5 ounces of gummy bears. The other type of treat bag will contain two small pieces of sidewalk chalk and four stickers.
Melanie and Bruce are in charge of purchasing supplies for the treat bags. They already purchased two 6-pound bags of gummy bears for $6.98 per bag and two rolls of 150-count stickers for $4.99 per roll. They still need to purchase the bubbles and sidewalk chalk.
Bubbles come in a pack of eight bottles, for $2.99. Melanie takes $25 to the store and purchases as many packs of bubbles as she can with the money.
Sidewalk chalk comes in a pack of 24, for $2.59. Bruce takes $20 to the store and purchases as many packs of sidewalk chalk as he can with the money.

Answers
Answer: B (population is total number of people who go to the mall, and sample is first 75 people at the mall)
Step-by-step explanation:
The question is only talking about the people who go to the mall (population), but the sample is specifically the first 75 people. This is because the survey was only asked to these random 75, so it is the sample.
Determine whether this system of equations has one solution, no solution, or infinitely many solutions. y=8x+2 y=-8x+2
Answers
Answer:
Step-by-step explanation:
Since you already have y isolated in one equation, you can plug it in and use it in the other equation2y = 8x + 122(4x + 6) = 8x + 128x + 12 = 8x + 12Get the x's to one side 12 = 12Meaning you have infinitely many solutions. Try plugging in any x value you can think of and the left side will always equal the right side. sox = 0 --> 8(0) + 12 = 8(0) + 1212 =12x = 1 --> 8(1) + 12 = 8(1) + 1220 = 20and so on.I graphed it here for you and the 2 functions are on top of each other which means at every x value y = 4x + 6 is equal to 2y = 8x + 12
A.) They are the same, so keep that in mind.
2.) are the initial values (b) different or the same?
A.) They are the same.
Now we can determine that the variables and initial values are the same, meaning that the two equations overlap on a graph. This means there are infinity solutions! :)

The Hydro water department has a monthly service charge of $13.90 and a volume charge of $1.45 for every 100 cubic feet of water.
The total monthly cost is equal to the service charge plus the charge for the volume used during the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have:
total monthly cost = volume charge + service charge
y = 1.45x + 13.90
If the Johnson family used 200 ft3 more water this month than last month, then they can expect
A. an increase in their water bill of $2.90.
B. an increase in their water bill of $27.80.
C. a decrease in their water bill of $2.90.
D. a decrease in their water bill of $27.80.
Answers
Answer: A
Step-by-step explanation:
In this question, you can disregard the initial $13.90 cost because we're only looking for an INCREASE in price. If the Johnson family used 200 cubic feet MORE of water, we need to multiply 2 * 1.45 which gets us 2.90. We multiply 2 by 1.45 because 200 represented in x is 2, since x is represented in hundreds.

A bag has 8 red marbles, 4 green marbles, and 2 yellow marbles. Bill draws a red marble from the bag and does not replace it. What is the probability of Bill drawing a yellow marble next? A. 1/7 B. 1/13 C. 2/13 D. 1/14
Answers
Answer:
c. 2/13
Step-by-step explanation:
The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.
So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.
7+4+2 = 13
2/13
So the probability of Bill drawing a yellow marble would be 2/13.

can someone explain how to do this, I don't want the answer?
Answers
The table is filled out by following these steps:
Step 1) Pick any number you want for x. Usually small values work such as x = 0, but you can choose anything you want. Be sure it fits within the window of the graph.Step 2) Replace x with that number you picked. If you picked x = 0, then y = (1/3)x becomes y = (1/3)*0 = 0. Meaning x = 0 leads to y = 0. The point (0,0) is on the graph.Step 3) Go back to step 1 and repeat the process with other x values. I recommend picking multiples of 3 so you can avoid fractional values of y.Follow those steps listed above so you can fill out the table. Each row of the table generates a different (x,y) point on the graph. Then draw a line or curve through the points. In this case, it's a straight line.
This straight line has a slope of 1/3 because y = (1/3)x is in slope-intercept form y = mx+b where,
m = 1/3 = slopeb = 0 = y interceptA slope of 1/3 means "go up 1, over to the right 3" when hopping from point to point along the line.
The unit rate and slope are the same thing when it comes to linear equations.
