Which of the following equations represents a line that is perpendicular to the line represented by x + 2y = 6 and passes through the point (3 , –4)?
Answer:
y=2x-10
Step-by-step explanation:
First change to equation into slope intercept form
2y=-x+6
y=-1/2x+3
slope=2 (beacause it is perpendicular)
y--4=2(x-3)
y+4=2x-6
y=2x-10

Answer:
1.25
Step-by-step explanation:
Answer:
7.5
Step-by-step explanation:
you put all numbers from least to greatest then you get the small nd big number nd subtract them

39.25 - 31.75 = 7.5
Roshanda was curious if students in her class would complete a maze faster if fast-paced music was playing in the background. She randomly assigned each student in her class to one of three groups: fast-paced music, slow-paced music, or no music. She timed each student as they individually completed a maze with their corresponding music (or no music) in the background. Students who worked with the fast-paced music, on average, completed the maze significantly faster than students in the other groups.
Can we conclude that the fast-paced music caused her classmates to finish the maze faster? Why?
(A) Yes, because the study included each student in her class
(B) Yes, because the adults were randomly selected
(C) Yes, because the students were randomly assigned to treatment and control groups
(D) Not necessarily, because the sample size was too small
(E) Not necessarily, because this wasn't an experiment
Answer: (E) Not necessarily, because this wasn't an experiment
Step-by-step explanation:
As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.
An experiment is planned and is scientific. It has more stringent requirements that ensure causation that Roshanda did not meet before she engaged in this trial so we cannot say for a fact that her findings are objective.
Answer: C. yes, the students were randomly assigned to treatment and control groups.

Answer:
20
Step-by-step explanation:
you use the pathagorian theorem which is a suqared plus b squared equals c squared.
it would be 12*12 plus 16*16 equals x squared. so 144 plus 256. that equals 400. then you take the square root of it which is 20. therefore x equals 20.

Gary has 30 blueberry muffins which is 30%Of all blueberry muffins in her basket how many muffins are in her basket
Answer:
100
Step-by-step explanation:
If 30% of all of her muffins are blueberry muffins, that means that 30% of 100% are blueberry. We want to find how many total muffins there are in her basket. Using a ratio:
30 muffins 30%
----------------- = --------
x muffins 100%
Cross multiply:
30 (100) = 30 (x)
3000 = 30x
3000/30 = 30x/30
100 = x
x muffins = 100 muffins
So there are a total of 100 muffins in Gary's basket.

Answer:
$15.78
Step-by-step explanation:
I) Remove tax:
$50.18 - $2.84 = $47.34
II) Construct an equation to find the cost of each shirt:
47.34 = 3s
III) Solve:
Divide each side by 3:
15.78 = s
Each shirt costed $15.78
Answer:
15.78

Lyn either travels by bus or walks
when she visits the shops.
The probability that she catches
the bus To the shops is 0.2
The probability that she catches
the bus FROM the shops is 0.6
0.2
Walk
a) Complete the tree diagram.
b) Show that the probability that Lyn
walks at least one way is 0.88.
I’m forced to write an explanation, sorry for the useless text
The probability tree has been drawn below and the probability that Lyn
walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.
What is probability?The probability of an event occurring is defined by probability.
Do not take underestimate probability it has several uses in daily life whether forecasts like that.
As per the given probability tree,
(a)
The probability in branches adds to 1 thus,
0.2 + probability that she walks to the shop = 1
Probability that she walks to the shop = 1 - 0.2 = 0.8
The probability in the same branches multiplies as,
The probability that she took a bus to the shop x from the bus she again took the bus.
Similarly, the tree diagram has been drawn below.
(b)
The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.
Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The correct option is C.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
In the two of the given equation, to eliminate x we need to make the coefficients of x in both the terms equal, therefore, if we take the LCM of the two terms then it will be 42.
Thus, to make the coefficient of x equal to 42, we need to multiply the first equation should be multiplied by 7 and the second equation by -6.

A circle has a diameter of 62.8 cm. What is the length of this circle's radius?
Pls give me an actual answer
Answer:
Step-by-step explanation:
The diameter of the circle is the length of a line going through the middle from one side to the other.
The radius is the length of a line going from the middle of a cricle to the side.
So, the radius is half of the diameter.
62.8÷2=31.4
The radius is 31.4 cm.
