∠1 and ∠2 are a linear pair. If the m∠2 = 33°, find the m∠1.

Answers

Answer:

157 degrees

Step-by-step explanation:

A linear pair is 180 degrees.

180-33 = 157

Answer:

m∠1 = 147°

Step-by-step explanation:

Since both angles are a linear pair, they both add up to 180°. This means that if m∠2 = 33°, then m∠1 would be 180°-33° which is 147°.

180°-33°=147°

What is the equation for the line that passes through (3, 2) and has a slope
equal to 12
3

Answers

Answer:

Step-by-step explanation:

Remark

I'm not sure I know what you intend for the slope. I will take it as 12/3 = 4

If that is the case then what you have so far is

Solution

y = 4x + b

The given point determines b

Givens

x = 3

y  = 2

Given point

2 = 4*3 + b

2 = 12 + b

b = 2 - 12

b = -10

The equation is y = 4x - 10

Many professional schools require applicants to take a standardized test.
Suppose that 1000 students take such a test. Several weeks after the test,
Pete receives his score report: he got a 63, which placed him at the 73rd
percentile. This means that... *
Pete scored less than about 73% of the test takers.
Pete scored less than about 63% of the test takers.
Pete scored more than about 63% of the test takers,
Pete scored more than about 73% of the test takers,
Pete's score was below the median.

Answers

Answer:

if pete placed in the 73rd percentile, this means that his score was better than 73% of the other test takers, so the fourth option: he scored more than about 73% of the test takers

Step-by-step explanation:

hope this helps :)

The meaning is Pete scored more than about 73% of the test takers.

What is data?

Data is information that has been translated into a form that is efficient for movement or processing.

Given situation:

Pete receives his score report: he got a 63, which placed him at the 73rd

percentile.

Percentile is a comparison score between a particular score and the scores of the rest of a group.

So,  73 percentile shows he had done better then 73% of people.

Hence, Pete scored more than about 73% of the test takers.

what is an equation of the line that passes through the points (-2,-7) and (-1,-3)

Answers

Answer:

y=4x+1

Step-by-step explanation:

First you need to solve for slope using the equation:

y2-y1/x2-x1

It doesn't matter what point is 1 or what point is 2. Lets just say that (-2,-7) is point 1, and (-1,-3) is point 2.

(-3)-(-7)/(-1)-(-2)=-4/-1=4

Next you find the y-intercept. To do this you can plug in plug in everything we know into the equation: y=mx+b, and solve for b.

(Lets use point one)

-7=4(-2)+b

-7=--8+b

1=b

Last we can put it all together.

y=4x+1

Why is it important to read division problems carefully before giving the answer

Step-by-step explanation:

1. Express 0.00456 in standard form.

Answers

Answer:

Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.

Answer: 4.56 x 10^-3

Step-by-step explanation: To convert scientific notation to standard form, all you have to do is move the decimal to the left or the right until you get a number that is more than 1 and less than 10, then count however many spaces you had to move and add that as your exponent over 10 (if you move left, the exponent is positive, and right is negative). Basically, this just lets you know that the actual number is that many times smaller or larger than the number in your answer.

A long year-end status report for work is 81 pages long. You need to print 12 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.96 each.

Give your answer to the nearest cent, only for the paper you use (partial reams are OK)

Answers

Answer:

770cents

Step-by-step explanation:

If a report is 81 pages long, 12 copies will be (81 * 12)pages long

12copies = 972 pages long

If 500 pages costs $3.96 each

972 pages will cost $x

Cross multiply

500x = 972 * 3.96

500x = 3,849.12

x = 3,849.12/500

x = 7.69824

Hence the cost of the reports is $7.69824

Convert to cents;

$1 = 100cents

$7.69824 = y

y = 7.69824 * 100

y = 769.824 cents

y ≈ 770 cents (to the nearest cent.)

Hence the paper is going to cost 770cents (to the nearest cent)

Answers

Answer: y = -3/4x - 0.75

Step-by-step explanation:

The slope needs to be negative so that it's perpendicular to

y = 3/4x - 1

The equation then looks like this

y = -3/4x

We can get an exact y intercept number by using the cordinates

Lets input cordinates (3,-3)

-3 = -3/4(3)

-3 = -2.25 - 75 ( I inferenced )

-3 = -3

now that we got the y intercept lets put it all together

y = -3/4x - 0.75

Anthony is laying concrete for a driveway. The driveway is to be 24 feet long by 11 feet wide by 8 inches deep. Answer parts (a) through (c)

(a) Determine the volume of concrete needed in cubic feet.

(b) If 1 cubic yard = 27 cubic feet, how many cubic yards of concrete are needed?

(c) If the concrete costs $36 per cubic yard, what is the cost of the concrete? Concrete must be purchased in whole cubic yards​

Answers

Answer:

a) The volume of concrete needed in cubic feet is 2,112. b) The number of cubic yards of concrete needed in cubic yards is about 79. c) The cost of the concrete using cubic yards is $2,844.

Step-by-step explanation:

a) The formula of the volume is l*w*d. 24 * 11 * 8 = 264 * 8 = 2,112.

b) The way to find this is that you take 2,112 and divide it by 27. Since the answer is 78.2 repeating, you round it up to 79 so it will fill up all of the concrete.

c) Since you need 79 cubic yards of concrete, you do 79 multiplied by $36 to get the total cost of $2,844.

Which of the following is the closest estimate for how many of the graduating seniors are going to an in-state school? A Bee MysteryRecent surveys around the world have found some very sad and troubling news. Bees are not doing well. According to Time: Science & Space, "an estimated ten million beehives ... have been lost since 2006." What's worse, scientists are not sure why. Most beekeepers will tell you that bees tend to die in large numbers every spring. This is normal and necessary to keep a hive of bees healthy. But when the deaths add up to more than half the bees in an entire country, that is something altogether different and dire. Scientists have called this "colony-collapse disorder" or CCD. This name describes the effect, though, and not the cause of the die-out. Scientists simply do not know what is killing the bees.Many things make it hard for bees. Varroa mites move into a colony and weaken it. Further, these mites carry viruses that attack those that survive. In addition, a new bacterium was recently discovered that attacks bees intestinally and kills them. Beekeepers go to great lengths to protect bees from these invaders, and for many years have been able to control them. All these attackers and the methods used to combat them do stress the bees, however.Many feel the problem is not some new threat, but a decline in the habitat available to bees. Development of grasslands once home to wild flowers and food for bees has been universal. Pavement makes it easy to drive, but it replaces wild grasses and other food sources for bees. Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health. We plowed under a varied habitat and plantedin many casesa single plant like beets. Then we sprayed all kinds of chemicals on the beets to keep other bugs away and in doing so also harmed bees. Now, to treat all the mites and other invaders, bee keepers use additional chemicals to kill the invaders. These chemicals also shorten the life of the bees. Have the use of chemicals, loss of habitat, and invading parasites made life impossible for bees? Experts continue to argue various theories, but few have any answers.Colony collapse disorder is perhaps one of the most mysterious problems modern science has tried to solve. Whether the problem is environmental or an unknown disease, we will all feel the effects if bees continue to decline. Bees affect almost every aspect of the human food chain. From the fruits, vegetables, and grains we eat, to the grasses and grains we feed our livestock, we depend on bees to keep us healthy. According to the Natural Resources Defense Council, bees account for 15 billion dollars in crops. Honey is a treasure for sure, but the real gold is in the strawberries, apples, peaches, and green beans we eat and need to stay healthy ourselves. All told, the outlook for bees is not good. The outlook for humans may not "bee" so good either.Read this sentence from the text:Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health.How does this line function in the text?A.
