Answer:
-90
Step-by-step explanation:
The full circle is 360 degrees, so is you turn one way say 10 degrees, then you would need to move 350 degrees in opposite direction.
So, in this case moving 270 one way would be equivalent to moving 360-270=90 degrees in the opposite direction

Which of the following is true of functions and their inverses?
The inverse of a quadratic function is not a function.
The inverse of a quadratic function is always a function.
The inverse of a linear function is not a function.
The inverse of a linear function is always a function.
The inverse of a quadratic function is not always a function, as it can assign multiple outputs to a single input. Conversely, the inverse of a linear function is always a function because it strictly assigns one output to each input.
Explanation:The presented statements about the nature of functions and their inverses are particularly related to the definition of a function. A function is a rule which assigns to each input exactly one output. Considering this, the inverse of a quadratic function is not always a function because it can assign multiple outputs (y-values) to a single input (x-value). This is why the graph of a quadratic function doesn't pass the 'horizontal line test', which is a criterion for a graph to represent a function.
On the other hand, the inverse of a linear function is indeed always a function. Because a linear function always assigns exactly one output to each input, its inverse will also satisfy the definition of a function.

What is the median of the data in this stem-and-leaf plot? 31.0 31.5 32.0 32.5 Untitled Stem and leaf plot. Vertical line separates each stem number from its first leaf number. First row. Stem 2. Leaves 6, 7, 7. Second row. Stem 3. Leaves 0, 2, 3, 3, 4. Third row. Stem 4. Leaves 0, 5. Key. 3 vertical line 0 means 30.
Answer:
32.5
Step-by-step explanation:
there are 4 rows
1 = 3
2 = 5
3 = 2
so there is 10 numbers
We go for the middle number which is 2-3 so the answer must be 32.5.
We know it is between 2-3 as the same as 1-10
1,2,3,4,5, ------ 6,7,8,9,10
So the imput numbers are listed 2 + 3 in your stem diagram where so 5 + 6 would be in the explanation. As 10 +1 = 11 then 11/2 = 5.5 - this means 5.5 = 32.5 as 33 would be the 6.

7. A box contains fifteen billiards balls, numbered 1 through 15. Anna draws a ball, records the number, and then returns it to the box. Then Vicki draws a ball. Find the probability of getting a 9 then a 3. *
The probability of first drawing a ball numbered 9 and then drawing a ball numbered 3, with each ball being returned to the box between draws, is 1 in 225.
Explanation:The question is about calculating the probability of two specific events occurring consecutively when drawing billiard balls from a box that contains numbers 1 through 15. We focus on the probability of first drawing a ball numbered 9 and then, after returning it, drawing a ball numbered 3. Since each ball is returned to the box before the next draw, the number of possible outcomes does not change between draws.
For the first draw, the probability of drawing a 9 is 1 out of 15 (since there is one '9' ball and 15 total balls). When the 9 ball is returned, the probability of drawing a 3 on the second draw is also 1 out of 15. Because these two events are independent (the outcome of the second draw does not depend on the outcome of the first), we multiply the probabilities of each event to find the overall probability of both events occurring:
Probability of drawing a 9 and then a 3 = (1/15) * (1/15) = 1/225.
This means there is a 1 in 225 chance of drawing a 9 followed by a 3 when both balls are returned to the box in between draws.
Write the unit rate for 5 revaluations in 50 seconds
The unit rate for 5 revaluations in 50 seconds is 1 revaluation per 10 seconds.
Explanation:To find the unit rate, divide the number of revaluations by the number of seconds. In this case, the unit rate is 5 revaluations per 50 seconds. To simplify this, divide both numbers by 5 to get 1 revaluation per 10 seconds. So, the unit rate is 1 revaluation per 10 seconds.

Step-by-step explanation:
12 squared + 12 squared = 288
square root of 288 = 16.97056275
The measure of the hypotenuse of an isosceles triangle with equal sides measureing 12 units is 16.97 units
What is an isosceles triangle?An isosceles triangle is a triangle that has two of its sides equal to each other . The base angle is also equal to each other.
The isosceles triangle is a right triangle. Since, one of the leg is 12 units, the other leg is also 12 units.
Using pythagora's theorem,
c² = a² + b²
c = √12² + 12²
c = √144 + 144
c = √288
c = 16.9705627485
c = 16.97 units
Therefore, the length of the hypotenuse is 16.97 units.

Results in 3 sets
Answer:
She bought 3 necklace and bracelet sets
If i can be brainliest that would be great
Step-by-step explanation:
Each set contains a necklace and a bracelet
∵ Each necklace cost $9.99
∵ Each bracelet cost $7.99
∴ The cost of one set = (9.99 + 7.99)
∵ She spent on them $53.94
- Add the cost of a necklace and the cost of a bracelet and
multiply the sum by x and then equate the product by 53.94
∴ (9.99 + 7.99)x = 53.94
∴ 17.98 x = 53.94
- Divide both sides by 17.98

Triangle DEF is similar to triangle ABC, and the length of EF is 5cm. What are the lengths of sides DE is 6cm and DF is 8cm centimeters?
The lengths of the sides corresponding to DE and DF in triangle ABC are 3.75cm and 5cm respectively as triangles DEF and ABC are similar and their sides are in proportion.
Explanation:Since triangles DEF and ABC are similar, then their corresponding side lengths are proportional. This means the ratio of the lengths of corresponding sides in both triangles remains constant.
Therefore, the lengths of the corresponding sides in triangle ABC will be in the same ratio as that of the sides in triangle DEF. Since we know the lengths of sides DE and DF in triangle DEF are 6cm and 8cm respectively, we can conclude that the lengths of the sides corresponding to DE and DF in triangle ABC will be in the same ratio as 6 and 8.
The ratio of 6 and 8 can be simplified to 3:4. Therefore, given that the length of side EF in triangle ABC is 5cm, we can apply cross-multiplication to find the lengths of the other sides. For example, using the ratio 3:4 to find the length corresponding to DE in triangle ABC, we would get 5/4 * 3 = 3.75cm. Similarly, "for DF we would get 5/4 * 4 = 5cm".

The lengths of sides DE and DF in triangle DEF are 6 cm and 8 cm, respectively.
Since triangle DEF is similar to triangle ABC, the corresponding sides of both triangles are proportional. This means that the ratio of any two corresponding sides in the two triangles will be the same. Let's denote the lengths of the corresponding sides in triangle ABC as follows: side AB corresponds to DE, side BC corresponds to EF, and side AC corresponds to DF.
Given that EF is 5 cm, we can set up the following proportion using the corresponding sides of the two triangles:
[tex]\[\frac{DE}{AB} = \frac{EF}{BC} = \frac{DF}{AC}\][/tex]
We know the lengths of DE and DF, so we can express the lengths of AB and AC in terms of the lengths of DE and DF, using the proportion:
[tex]\[\frac{6}{AB} = \frac{5}{BC} = \frac{8}{AC}\][/tex]
From the proportion, we can solve for AB and AC:
[tex]\[AB = \frac{6}{5} \times BC\][/tex]
[tex]\[AC = \frac{8}{5} \times BC\][/tex]
Since we do not have the actual length of BC, we cannot determine the exact lengths of AB and AC. However, we can express them in terms of BC, the corresponding side in triangle ABC. If BC is known, we can simply multiply it by the respective ratios to find AB and AC.
In conclusion, the lengths of sides DE and DF in triangle DEF are 6 cm and 8 cm, respectively, and the lengths of the corresponding sides AB and AC in triangle ABC can be calculated once the length of BC is known, using the ratios derived from the similarity of the triangles.

1-bedroom apartments in New York had an average rent of 800 dollars in 2000
The best interpretation of this y-intercept is the model indicates that 1-bedroom apartments in New York had an average rent of 800 dollars in 2000.
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Thus, y-intercept of y = f(x) is y = f(0)
In this case, x be the number of years after the year 2000.
Then we can show that x = 0, represents the year 2000 itself.
Now, the y-intercept is the value of y when we have x = 0.
So, the y-intercept gives information about the average price of a 1-bedroom apartment in the year 2000.
