How many revolutions is 900 degrees
9 revolutions
3 revolutions
2.5 revolutions
4.5 revolutions
Answers
Answer: 2.5
Step-by-step explanation:
One complete revolution equals 360 degrees. To find out how many revolutions 900 degrees represent, you divide 900 by 360 resulting in 2.5 revolutions.
Explanation:To ascertain the number of revolutions in 900 degrees, consider that a full circle encompasses 360 degrees. Dividing 900 by 360 yields 2.5, revealing that 900 degrees translates to 2.5 revolutions. This calculation stems from the fundamental concept that each complete revolution covers 360 degrees. In essence, the formula involves dividing the given degree measure by the standard degree value for a full revolution. Consequently, this approach facilitates the conversion of angular measurements into a more comprehensible representation of revolutions, aiding in the interpretation of rotational or circular motions within mathematical or physical contexts.

Law of sines.
The sine is a trigonometry function that is equal to the ratio of the opposite side of the given triangle and is considered to be from e right-angled triangle. The question states the start fraction for the sine in upper case A and the end fraction for lower case B. Hence the answer is given.
Answer is over c end fraction in triangle BCD, where d is equal to 3, b is equal to 5 and angled is at 25 degrees.
Thus the statement refers to the start and the end fractious of the upper and lower cases found in the right-angled triangle and has a function of sine.The possible approx. the measure of the angle B is 20 and 110 degrees is correct.Find more information about the law of sins.
brainly.com/question/13773515.
By applying the Law of Sines and solving for sin(B), we find that the possible approximate measures of angle B are 45° and 135°. Therefore, the correct answer is option D.
To determine the possible measures of angle B in triangle BCD using the Law of Sines, start with the given information:
d = 3, b = 5, and m∠D = 25°.Using the Law of Sines:
sin(D) / d = sin(B) / bSubstitute the known values:
sin(25°) / 3 = sin(B) / 5Calculate sin(25°):
sin(25°) ≈ 0.4226Set up the equation:
0.4226 / 3 = sin(B) / 5Cross-multiply to solve for sin(B):
3 × sin(B) = 5 × 0.42263 × sin(B) = 2.113sin(B) = 2.113 / 3sin(B) ≈ 0.7043We now find B using the sine inverse function:
B = sin-1(0.7043) ≈ 45° or 135°Thus, the possible approximate measures of angle B are 45° and 135°.
The correct answer is option D: 45° and 135°.

Mr. fudge is going to roll two fair dice. what is the probability that the sum will be 4 or less?

Answer:
I think it's 8\12
Step-by-step explanation:
there are numbers from 1 to six on each dice that means there are 12 numbers on the two dice together and it says four or less there are 1,2,3 and four on the dice that is four or less double that and you get 8when you put that over 12 it becomes 8/12. I hope it helps alot
The probability of rolling a sum of 4 or less with two dice is 6 out of 36 outcomes, which simplifies to 1/6 or 0.1667 when rounded to four decimal places.
Explanation:To calculate the probability that the sum of two rolled dice will be 4 or less, we can list all possible outcomes (the sample space) and then count the favorable outcomes. A single six-sided die has 6 faces, so the total number of outcomes when rolling two dice is 6 × 6 = 36. The pairs of dice that sum to 4 or less are: (1,1), (1,2), (1,3), (2,1), (2,2), and (3,1). There are 6 such pairs, so the probability of rolling a sum of 4 or less is 6/36, which simplifies to 1/6.
The probability should be rounded to four decimal places if necessary, but in this case, the fraction simplifies exactly to 1/6. Therefore, the probability is 0.1667 when rounded to four decimal places.

Answers
Answer:
125=15d+50
Step-by-step explanation:
Subtract what she has from what she needs so 125-50=75
Then divide that by the amount of money she makes a day to figure out how many days she'll need to work so, 75/15=-5
She will have to work 5 days in order to have enough to buy her ticket
Answer:50+15d=125
5 days
Step-by-step explanation:
Subtract 50 from both sides to get 15d=75 then divide both sides by 15 and the answer is 5 days

The fictitious state of Aribraska has a graduated state income tax.
Residents pay 3% on the first $15,000 of income.
The next $25,000 earned is taxed at a rate of 5%.
Any money earned above $40,000 is taxed at 7%.
The income tax for Aribraska is modeled by a piecewise defined function.
Over which part of the domain is the piecewise function defined as
f(x) = 0.05x – 300?
An Aribraska resident who earns $32,000 would owe how much in tases?
$1,300
$1,600
$1,740
Answers
Answer:
$1300
Step-by-step explanation:
The piecewise function is defined as f(x) = 0.05x - 300 over the income range of $15,000 to $40,000. An Aribraska resident who earns $32,000 would owe $1,600 in taxes.
Explanation:The piecewise function is defined as f(x) = 0.05x - 300 over the part of the domain where the income is between $15,000 and $40,000. This is because the tax rate of 5% is being applied to the income in this range. For any income above $40,000, the tax rate is 7%, so the function would not be equal to 0.05x - 300.
To calculate the amount of taxes owed by an Aribraska resident who earns $32,000, we need to determine the income range that applies to this amount. Since $32,000 is within the range of $15,000 to $40,000, we can use the piecewise function to calculate the taxes:
f(32,000) = 0.05(32,000) - 300 = 1,600
Therefore, an Aribraska resident who earns $32,000 would owe $1,600 in taxes.

A 3" × 5" rectangle is dilated by a scale factor of 2. what will its new perimeter be?
Answers
When u dilate a rectangle by a scale factor of two, each side measurement is multiplied by 2, therefore the new rectangle is a 6” X 10”
Because it is a rectangle that means 2 sides are 6” and 2 other sides are 10” so you would add 10+10+6+6 which gets u 32.
Answer:
6" × 10"
Step-by-step explanation:
Because the dilation is a whole number we know the rectangle will be enlarging, and we are told this is by two. So you will take and multiply the dimensions by two.

Answers
Answer:
31.2
Step-by-step explanation:
Ratio shows us the number of times a number contains another number. The weight of the fruit box is 31.2 lbs.
What is Ratio?A ratio shows us the number of times a number contains another number.
As it is given the ratio of the fruits oranges, apples, and pears is 2:5:6. And the weight of the oranges in the box is 4.8 lbs.
Let's assume that the weight of the oranges, apples, and pears is 2x, 5x, and 6x respectively.
Now, as the weight of the oranges is 4.8 lbs, therefore,
The weight of the oranges, 2x = 4.8 lbs
x = 2.4 lbs
Now, as we know the value of x, therefore, the weight of the fruit box is,
[tex]\begin{aligned}\text{Total weight of the fruit box} &= 2x + 5x+ 6x \\&=13x \end{aligned}[/tex]
Now, substitute the value of x, therefore, we can write it as,
