Question 2: D, 84°
Step-by-step explanation:
Answer:
2. d. 84°
3. d. 90°
Step-by-step explanation:
Q2
32 + 64 + x = 180x + 96 = 180x = 84°Q3
20 + 70 + x = 180x + 90 = 180x = 90°
A line passes through the points (2, 1) and (4, 9). What is its equation in slope-intercept
form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Explanation:
Let's find the slope of the line through those two points.
[tex](x_1,y_1) = (2,1) \text{ and } (x_2,y_2) = (4,9)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{9 - 1}{4 - 2}\\\\m = \frac{8}{2}\\\\m = 4\\\\[/tex]
Then we can apply point-slope form to transform it into slope-intercept form.
[tex]y-y_1 = m(x - x_1)\\\\y-1 = 4(x - 2)\\\\y-1 = 4x - 8\\\\y = 4x - 8+1\\\\y = 4x - 7\\\\[/tex]
Answer:
let point A be (2,1) and
B be (4,9)
Now,Slope =y2-y1-----------------
x2-x1= 9-1---------
4-2=8-----
2=4Select the correct answer. In which of the scenarios can you reverse the dependent and independent variables while keeping the interpretation of the slope meaningful? A. As the number of cigarettes smoked in a day increases, the risk for lung cancer increases. B. As the age of an infant increases, the height of the infant increases. C. As the number of vehicles in a city increases, the amount of pollution in the city increases. D. As the concentration of salt in water increases, the density of water increases. E. As the number of calls made by a cell phone increases, the cell phone bill amount increases. Reset Next
Answer:
In Option A, we can see that the reverse may not be true as the increase in the risk for lung cancer may not necessarily mean an increase in cigarette smoked in a day. For example, high risk of lung cancer may be due to high exposure to asbestos dust too.
In Option B, again we can see that the reverse may not be true as an increase in the height of an infant does not necessarily mean that the age of the infant is increasing too. For example the infant may have a rapid gain in height even if the age is not increasing as rapidly.
In Option C, too, that an increase in the amount of pollution in a city does necessarily mean that the number of vehicles in the city has increased. For example, this increase in pollution may be due to the establishment of a high pollution causing industry in the city or in it's vicinity.
Likewise, in Option D, an increase in the density of water does not necessarily mean that the concentration of salt in the water has increased.
Only in Option E do we see a possible reverse dependence happening because an increase in the phone bill amount does usually mean an increase in the number of calls made by the cell phone.
So, in the given list of Options only in Option E can we reverse the dependent and independent variables while keeping the interpretation of the slope meaningful.

There are 6 marbles in a bag: 1 blue, 1 red, 1 white, 1 yellow, 1 green, and 1 black. Mary picks one marble at random and then her sister chooses another from those left in the bag.
What is the probability that Mary picks the red marble and her sister picks the blue marble?
Answer:
1 in 30
Step-by-step explanation:
1 in 6 chance Mary picks the red marble in the first place. After this there is a 1 in 5 chance her sister picks the blue one. 5 multiplied by 6 is 30.
The probability that Mary picks the red marble and her sister picks the blue marble is [tex]\frac{1}{30}[/tex] .
Concept:Firstly, we need to find the probability of Mary picking a red marble from the 6 marbles.Secondly. we need to find the probability of Mary's sister picking a blue marble from the 5 left marbles.As both are mutually exclusive events , the required probability is the multiplication of both above.How to solve the given question?P(A) = Mary picking a red marble out of 6 marbles = [tex]\frac{1}{6}[/tex]P(B) = Mary's sister picking a blue marble out 5 left marbles = [tex]\frac{1}{5}[/tex]P(E) = Required probability = P(A) × P(B) = [tex]\frac{1}{6}[/tex] × [tex]\frac{1}{5}[/tex] =Thus, the probability that Mary picks the red marble and her sister picks the blue marble is [tex]\frac{1}{30}[/tex] .

1 minus StartFraction 9 over 16 EndFraction
This is the same as writing 1 - 9/16
======================================================
Explanation:
9/16 is the fraction 9 over 16
It is a shorthand way of saying 9 squares are shaded out of 16 total.
When writing 1 - 9/16 or 1 - (9/16), this represents the number of white squares that aren't shaded blue.
------------
This is what happens when you simplify the expression
1 - 9/16
16/16 - 9/16
(16-9)/16
7/16
This shows that there are 7 white squares.
------------
Or if you want, you can think of it like this:
16 squares total, 9 are blue
16-9 = 7 squares are white
7/16 is the fraction of squares that aren't shaded blue.
A company earns $7 for every book sold. The company can sell 200 books in 2 hours. At this rate, how much money would the company earn in 8 hours of selling books?
Answer:
$5,600
Step-by-step explanation:
1. divide 200 by 2 (this gives you the rate for 1 hour of book sales)
2. multiply the answer by 8 hours
3. multiply your answer (800) by $7
4. You solved it! $5,600 is how much money a company would earn if they sold books for 8 hours.
Answer:
The company earns $5,600 per 8 hours of book sellingStep-by-step explanation:
Step 1
Find how much books the company sells in 8 hours of selling books
To find this, we see that 2 hours = 200 books. Also, 8/2=4. That means that if we multiply 200 by 4, then we will get our total amount of books sold in 8 hours.
200x4=800
800 books sold in 8 hours
Step 2
Find how much money does 800 books equal to get FINAL ANSWER
To find this, we need to know the price of 1 book, the price of one book is 7$, that means that if we do 7$x800books, then we get our FINAL ANSWER
7x800=$5,600
Hence, the company earns $5,600 for sellings books for 8 hours.PLSS HELPP

What is the price, in dollars, of 11 towel?
Answer: $54.45
Step-by-step explanation:
First, we will find the price of one towel.
-> We will divide the cost by the towels bought.
$39.60 / 8 = $4.95
Now, we can find the price of 11 towels.
-> We will multiply the cost of one towel by 11 to find the total cost.
$4.95 * 11 = $54.45
Answer:
$54.45
Step-by-step explanation:
Given:
Number of towels = 8
Money spent on towels = $39.60
To Find:
What is the price, in dollars, of 11 towel?
Solve:
Since, each towels cost the same amount then we can divide the cost by number of towels.
39.60/8 = 4.95
Thus, Each towel costs $4.95
Then we are trying to find the price in dollars of 11 towels.
Knowing that 1 towels cost $4.95 then 11 towels:
4.95 × 11 = $54.45
