Which is a correct classification for the triangle? equiangular triangle obtuse triangle acute triangle right triangle Triangle with two angles labeled 22 degrees and 63 degrees

Answers

None of the classifications. 22 + 22+ 63 = 107 degrees but a triangle mus t have 180 degrees.

Answer:

The triangle is obtuse triangle.

Step-by-step explanation:

Given two angles of triangle labelled as 22° and 63°. we have to classify the triangle.

Let the third angle be x°

By angle sum property of triangle,

22°+63°+x=180°

⇒ 85°+x=180° ⇒ x=95°

An equiangular triangle is a triangle where all interior angles are equal.

An obtuse triangle is a triangle in which one of the angles is obtuse angle.

An acute triangle is a triangle have all three angles acute.

For right triangle one angle must be of 90°.

Hence, one angle of the triangle is 95° which is obtuse i.e greater than 90°

∴ Given triangle is obtuse.

How can I rename 82 thousands?

Answers

82,000. hope that helped

Final answer:

82 thousands can be renamed as 8 ten thousands and 2 thousands, or as 0.082 hundred thousands in the decimal system.

Explanation:

Renaming 82 thousands means expressing this amount in another unit of place value. In the standard decimal system, the next unit larger than thousands is ten thousands. The digit in the ten thousands place represents the number of ten thousands in that number. If you have 82 thousands, this equals 8 ten thousands and 2 thousands, because 82 divided by 10 equals 8 with a remainder of 2. Therefore, 82 thousands can be renamed as 8 ten thousands and 2 thousands. Similarly, 82 thousands can also be expressed as 0.082 hundred thousands, as 82 divided by 1000 equals 0.082.

A drivers uses 2.7 gallons of gasoline to drive her car 72.9 miles. what was her cars mileage?

Answers

divide 72.9 by 2.7

72.9 / 2.7 = 27 miles per gallon

Answer:

27 mi/gal

Step-by-step explanation:

The car mileage refers to the number of miles that a vehicle can run per gallon of fuel. A higher car mileage is desirable because it means that the vehicle has a better performance (travels more distance per gallon of fuel.) A driver uses 2.7 gallons of gasoline to drive her car 72.9 miles. The car mileage is:

72.9 miles / 2.7 gallon = 27 miles/gallon

The car can travel 27 miles per gallon of gasoline.

A cylinder has a height of 16 cm and a radius of 5 cm. A cone has a height of 12 cm and a radius of 4 cm. If the cone is placed inside the cylinder as shown, what is the volume of the air space surrounding the cone inside the cylinder? (Use 3.14 as an approximation of π.)

A.452.16 cm3

B.840.54 cm3

C.1,055.04 cm3

D.1,456.96 cm3

Answers

Ok so the end equation here is going to be VCy-VCo=
air space. So we need to find the volume of the cone and the volume of the cylinder.

Lets start with the volume of the cylinder since its easiest. The volume of a cylinder is Pi*r^2*h = Volume.
We already know that the radius is 5 and the height is 16 so lets plug them in and solve. 3.14*5^2*16=1,256

Now lets solve to find the volume of the cone. Now this ones a bit harder, the equation is: Pi*r^2*(h/3)= Volume.
The radius is 4 and the height is 12, so now just solve! 3.14*4^2*(12/3)=201

Now we just need to subtract the Volume of the cylinder from the volume of the cone. 1,256-201=1,055

What is the scale factor of 3,6 and 4.5, 9

Answers

To determine scale factor, we have to see what the common factor we multiply each term by in order to get the other two terms. To do this, we have to divide the corresponding values: 4.5/3 = 1.5. 9/6 = 1.5. Thus, since both pairs of numbers produced the same factor, it is 1.5

Final answer:

The scale factor between the numbers (3, 6) and (4.5, 9) is 2, since the second number in each pair is twice as large as the first number.

Explanation:

The scale factor is a ratio that describes how to enlarge or reduce the dimensions of an object to create a new object that is similar to the original. To figure out the scale factor between two similar figures, we calculate the ratio of any two corresponding lengths in the figures.

As per the student's question:

For the pair of numbers (3, 6), the scale factor can be calculated by dividing 6 by 3, which gives us a scale factor of 2.For the pair of numbers (4.5, 9), dividing 9 by 4.5 gives us a scale factor of 2 as well.

In each case, the corresponding lengths in the second object are twice those in the first, meaning you can multiply the dimensions of the first figure by 2 to get the dimensions of the second figure.

Productive use of machinery on a farm made it possible to decrease the number of tractors by 12 how many tractors does the farm have now if it used to have 1.5 times more

Answers

So first off, the answer to this is 24 now think of x as the real or original sum or amount, also y as the new sum or amount.
y * 1.5 is x, and y+12 is x. Now flip that to figure out what is y, also which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to minus 12, which can help you get the answer which is 24.

The probability that a given computer chip will fail is 0.02. find the probability that of 5 delivered chips, exactly 2 will fail.

Answers

Since the chip either passes or fails, this problem is one in binomial probability, with p(fail)=0.02 and n=5.

If your calculator features probability functions such as binompdf(n, p), use it.
Mine is a TI-83 Plus.

The probability that exactly two chips will fail is

binompdf(5,0.02,2) = 0.0038. This is quite a small probability.

Probability of an event is the measure of its chance of occurrence. The probability that of 5 delivered chips, exactly 2 will fail is 0.003764768 or approx 0.0004

How to find that a given condition can be modeled by binomial distribution?

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

For the given case, as failing or working of chips usually doesn't depend on other chips' working condition, so they're independent(assuming). There are two cases for each chip's working(random experiment) that it is either working or failed.

If we take Success of the considered binomial experiment(working status of chip) = Chip working fine

Then, as per given data, we have

P(chip working fine ) = 1 - P(chip not working) = 1 - 0.02 = 0.98 = Probability of success in Bernoulli experiment (chip's working status).

There are n = 5 chips, p = probability of success = 0.98, q = 1-p = 0.02

If we take X = number of chips of of 5 chips working, then:

[tex]X \sim B(n = 5, p = 0.98)[/tex]

Then, the needed probability is P(Exactly two chips fail) = P(Exactly 5-2 = 3 chips work) = P(X = 3)

And thus, the needed probability is calculated as:

[tex]P(X = 3) = \: ^5C_3(0.98)^3(0.02)^2 = \dfrac{5.4.3}{3.2.1} \times 0.941192 \times 0.0004 = 0.003764768[/tex]

(using the probability mass function of binomial distribution).

Thus, the probability that of 5 delivered chips, exactly 2 will fail is 0.003764768 or approx 0.0004

Given two angles that measure 50 degrees and 80 degrees and a side that measures 4 feet, how many triangles, if any, can be constructed?

Answers

Can 2 sides be 4 feet because given those angles you'd have to make an isosceles triangle (where 2 sides are the same length). If so, id say 2 triangles because the 4 ft side could be one of the congruent sides or the base side. If you cant use it for 2 sides, just 1 triangle can be made

Angle 1 = 50°

Angle 2 = 80°

Angle 3 = x°

The sum of the interior angles of a triangle is 180°

50 + 80 + x = 180

130 + x = 180

x = 180 - 130

x = 50°

Hence, angle 3 = 50°.

Now, we see that two angles of the triangle are equal, hence, the triangle that will form will be an isosceles triangle.

An isosceles triangle has two equal sides whose opposite angles are equal.

So, there could be a chance that two sides of the triangle are 4 ft in length.

a rectangle has a perimeter,p, length,l, and width,w. which of the following represents l in terms of p and w?

Answers

P = 2 (l + w)
l = length
w = width

so
l + w = P/2
l = P/2 - w

Final answer:

To find the length (l) of a rectangle in terms of the perimeter (p) and width (w), use the formula l = (p - 2w) / 2.

Explanation:

To find the length (l) of a rectangle in terms of the perimeter (p) and width (w), we can use the formula for the perimeter of a rectangle, which is given by:

p = 2l + 2w

Now, solve the equation for l by subtracting 2w from both sides:

p - 2w = 2l

Finally, divide both sides by 2:

l = (p - 2w) / 2

so. she charges then for every hour 1 1/5x. First let's convert that mixed fraction to "improper" and check what is "x". Bearing in mind that, the 470 is for 7 hours of work, but the hourly rate only applies to the 1 1/5x, NOT the fixed consulting fee rate.

[tex]\bf x+7\left( 1\frac{1}{5}x \right)=470\implies x+7\left( \cfrac{1\cdot 5+1}{5}x \right)=470 \\\\\\ x+7\left( \cfrac{6}{5}x \right)=470\implies x+\cfrac{42x}{5}=470\implies \cfrac{5x+42x}{5}=470 \\\\\\ 5x+42x=2350\implies 47x=2350\implies x=\cfrac{2350}{47}\implies \boxed{x=50}[/tex]

what's her hourly rate? well (6/5)x

What are the 3 numbers in Marlene's puzzle if the quotient of a & c is 8, the quotient of a & b is -16, the quotient of b & c is -0.5, the product of a & c is 2, the product of a & b is -1,?

Answers

a = 4, b = -0.25, c = 0.5

or a = -4, b = 0.25, c = -0.5

Write down what you know in the form of equations:

a / c = 8

a / b = -16

b / c = -0.5

a * c = 2

a * b = -1

Now see if you can express one variable in terms of another. The a * c = 2 expression looks like a nice place to begin.

a * c = 2

Divide both sides by c

a = 2/c

Now look for another expression that uses a and c. The expression a/c = 8 looks like a good possibility.

a/c = 8

Substitute the expression defining a in terms of c into the expression

(2/c)/c = 8

Multiply both sides by c

2/c = 8c

Multiply both sides by c again

2 = 8c^2

divide both sides by 8

2/8 = c^2

1/4 = c^2

Take the square root of both sides

1/2 = c

0.5 = c

Now that we know the value for c, Calculate a using the a = 2/c expression we made.

a = 2/c = 2/.5 = 4

So we now know that a = 4, and c = 0.5

Look for an expression using b that we can solve. a / b = -16 looks like a good place to try

a / b = -16

Substitute the known value of a

4 / b = -16

Multiply both sides by b

4 = -16 b

Divide both sides by -16

-4/16 = b

Simplify

-0.25 = b

So a = 4, b = -0.25, c = 0.5

Verify using the equations given

a / c = 8: 4 / 0.5 = 8 Correct.

a / b = -16: 4 / (-0.25) = -16 Correct

b / c = -0.5: -0.25 / 0.5 = -0.5 Correct

a * c = 2: 4 * 0.5 = 2 Correct

a * b = -1: 4 * -0.25 = -1 Correct

All of the quotients and products come out as they should, so the values determined for a,b,c are correct.

Note: Since the square root was taken for the equation

0.25 = c^2

0.5 = c

The value of either 0.5, or -0.5 is correct for c. So this problem actually has 2 solutions.

They are a = 4, b = -0.25, c = 0.5

or a = -4, b = 0.25, c = -0.5
