what fraction are the water rides
1/4 is the fraction of the water rides
How to determine what fraction are the water rides?A fraction represents the parts of a whole or collection of objects e.g 3/4 shows that out of 4 equal parts, we are referring to 3 parts.
Given: the diagram shown in the image
Examining the image, you will notice that the Family ride(cyan color) divides the circle into two equal parts. That implies the Family takes half (1/2) of the whole thing.
Also, the combined total of Thrill and Water rides take the remaining half (1/2). Also, notice that the Thrill and Water rides further divide the total into two equal parts. That is:
(1/2) / 2 = 1/4
Therefore, the fraction of the water rides is 1/4

Determine if a triangle can have the given side lengths. If yes, which type of triangle is formed by the side lengths. Choose the correct answer for both rows of the table. HELP GODDD PLZ PLZ PLZ HELP
Answer:
B and H.
Step-by-step explanation:
By the triangle inequality, any two sides of a triangle must be greater than the remaining side.
Triangle 1)
The side lengths are 9, 40, and 41.
We only need to check the two smaller sides. 9 + 40 = 49 which is indeed greater than 41. Therefore, this is indeed a triangle.
Remember that if:
\(c^2=a^2+b^2\)
We have a right triangle.
\(c^2>a^2+b^2\)
We have an obtuse triangle.
And if:
\(c^2<a^2+b^2\)
We have an acute triangle.
In all of these, c is the longest side.
Therefore, we will substitute 41 for c and 9 and 40 for the others:
\(41^2\text{ }?\text{ }40^2+9^2\)
Evaluate:
\(1681=1681\)
Since the two values are equivalent, the first triangle is a right triangle.
Triangle 2)
Again, adding up the two smaller sides gives that 8 + 10 = 18.
However, 18 is less than 21, so it does not satisfy the triangle inequality.
Therefore, the given side lengths cannot form a triangle.

An automobile manufacturer can produce up to 300 cars per day. The profit made from the sale of these vehicles can be modelled by the function p(x) = -x²+ 350x-6600 where p(x) is the profit in thousand Rupees and x is the number of automobiles made and sold. Answer the following questions based on this
model:
(i) When no cars are produce what is a profit/loss?
(ii) What is the break even point? (Zero profit point is called break even)?
(iii) What is the profit/loss if 400 cars are produced?
i) The profit/loss when no cars are produced is a loss of 6600 Rupees.
II) The break even point is at 20 cars
III) The profit/loss if 400 cars are produced is; a loss of 13400Rupees.
How to solve Profit functions?(i) When no cars are produced, x = 0.
Thus, plugging this value into the function p(x) = -x² + 350x - 6600, we have;
p(0) = -0² + 350(0) - 6600 = -6600.
Therefore, the profit/loss when no cars are produced is a loss of 6600 thousand Rupees.
(ii) The break-even point is the point at which the profit is zero, i.e., p(x) = 0. Setting p(x) = 0 and solving for x, we find that;
-x² + 350x - 6600 = 0
x = 20
Therefore, the break-even point is x = 20 cars. T
(iii) If 400 cars are produced, the profit can be found by plugging this value into the function p(x) = -x² + 350x - 6600.
We find that p(400) = -400² + 350(400) - 6600
= -160000 + 140000 + 6600 = -13400. Therefore, the profit/loss if 400 cars are produced is a loss of 13400 Rupees.

A neighborhood is trying to set up school carpools, but they need to determine the number of students who need to travel to the elementary school (ages 5-10), the middle school (ages 11-13), and the high school (ages 14-18). A histogram summarizes their findings:
Histogram titled Carpool, with Number of Children on the y axis and Age Groups on the x axis. Bar 1 is 5 to 10 years old and has a value of 3. Bar 2 is 11 to 13 years old and has a value of 7. Bar 3 is 14 to 18 years old and has a value of 4.
Which of the following data sets is represented in the histogram?
{3, 3, 3, 7, 7, 7, 7, 7, 7, 7, 4, 4, 4, 4}
{5, 10, 4, 11, 12, 13, 12, 13, 12, 11, 14, 14, 19, 18}

{3, 5, 10, 11, 13, 7, 18, 14, 4}
The correct answer is that the data set {3, 7, 4} is represented in the given histogram.(option-a)
The given histogram represents the number of children in each age group who need to travel to school. Since the histogram has only three bars, we can conclude that there are only three age groups.
The first bar represents children aged 5-10, of which there are 3. The second bar represents children aged 11-13, of which there are 7. The third bar represents children aged 14-18, of which there are 4.
Therefore, the data set that is represented in the histogram is:
{3, 7, 4}
None of the other data sets given match the values in the histogram. The first data set has duplicate values and is not sorted by age group. The second data set includes ages that are not represented in the histogram. The third data set has values for ages 6, 11, 12, 13, 14, 15, 17, and 18, but the histogram does not have bars for all those ages. (option-a)

Angle Q is 51°
Angle R is 96°
(x=5 and the exterior angle is 84°)
Step-by-step explanation:
Exterior Angle Theorem says that angle that's outside the triangle (extend a side and see the angle between the side extension and the side) IS Equal to the sum of the two angles that are farther away.
17x - 1 = 33 + 10x + 1
Get all the x's on one side of the equation.
17x-10x - 1 = 33 + 10x-10x+1
7x - 1 = 33 + 1
7x - 1 = 34 add 1 to both sides
7x = 35 divide by 7
7x/7 = 35/7
x = 5
Not finished ! Find Angle Q
10x+1 = 10(5)+1= 51°
Angle PRQ is insidethe triangle. All the angles of a triangle add up to 180°

find the value of the expression -x^3+3 x^2-x+20 if x=-1
The value of the expression -x³ + 3x² - x + 20 when x = -1 is 23.
What is the value of the given expression when x = -1?Given the expression in the question;
-x³ + 3x² - x + 20
x = -1To determine the value of the expression,
First, we substitute -1 for x in the expression:
-( -1 )³ + 3( -1 )² − ( -1 )) + 20
Next, we simplify each term using the order of operations (also known as PEMDAS):
-( -1 )³ = -( -1 ) = 1
(recall that the exponent is evaluated first, then the negative sign is applied)
3( -1 )² = 3(1) = 3
(recall that the exponent is evaluated first)
-( -1 ) = 1
(recall that subtracting a negative is the same as adding a positive)
Now, putting these simplified terms back into the original expression, we get:
1 + 3 + 1 + 20
Finally, we add these terms together to get the final answer:
23
Therefore, the value of the expression is 23.

A cylinder with a radius of 3 inches and height of 5 inches.
Recall the formula S A = 2 pi r squared + 2 pi r h.
48 square inches
151 square inches
251 square inches
414 square inches
Answer: 151sq
Step-by-step explanation:
You may use the formula for a cylinder's surface area to determine the candle's surface area:
SA = 2πr^2 + 2πrh
Given:
Radius (r) = 3 inches
Height (h) = 5 inches
Pi (π) = 3.14 (approximately)
Now, enter the values into the formula to get:
SA = 2 * 3.14 * 3^2 + 2 * 3.14 * 3 * 5
SA = 2 * 3.14 * 9 + 2 * 3.14 * 3 * 5
SA = 56.52 + 94.2
SA ≈ 150.72 square inches
The candle has a surface area of around 151 square inches.
