33°
Since it's a right triangle that has an immediate 90° angle, we have 90°'s left to worry about. We have two angles to worry about it, and since one angle is bigger than the other by 24°, it means that the gap between them is 24°. After doing some mental math, you get 57° + 33°. The gap between them is 24°, and they add up to 90°. Finally, since you're looking for the smaller angle in this problem, then 33° would be your answer.

p(x) = x² + 9.[tex]q(x) = \sqrt{x + 8}[/tex]From the composition of q and p, we have that:
[tex](q \circ p)(x) = q(p(x)) = q(x^2 + 9) = \sqrt{x^2 + 9 + 8} = \sqrt{x^2 + 17}[/tex]
At x = 8, the numeric value is found replacing the lone instance of x by 8, hence:
[tex]\sqrt{8^2 + 17} = \sqrt{81} = 9[/tex]
From the composition of p and q, we have that:

Answer:
A.
Step-by-step explanation:
There is a difference in collecting information about a number, such as height, versus a subjective value, such as favorite ice cream. One can be quantified, and the other is described. This is the difference between categorical and numerical variables. Categorical variables may also be described as qualitative variables. Numerical variables may also be described as quantitative variables.
Not all data that use numbers are truly numerical. For example, if you survey individuals to get their area code, the result will show a variety of numbers. However, area codes are not a value that is logical to use for analysis. It is not useful to take the average of a group of social security numbers either. Use caution when classifying variables.
A bar graph or bar chart is typically used to represent categorical data.
Bar charts are used to represent categorical univariate data.

Complete the table using equivalent ratios.
The numbers that correctly complete the ratios if Pat drives 36 kilometers for every 3 liters of gas are 4 and 11.
What is a ratio?A ratio is an expression commonly used in mathematics to show the relationship or proportion between two elements. For example, the proportion of cats to dogs might be expressed as 10:12, which means there are 10 dogs for every 12 cats.
How to complete the missing ratios?The ratio given is 3 liters of gas to 36 kilometers, which means that to drive 36 kilometers 3 liters of gas are required. Let's simplify this expression:
36 / 3= 12. This means that for every liter you can drive 12 kilometers. Based on this let's find the new ratio:
48 kilometers / 12 = 4 liters of gas
132/ 12 = 11 liters of gas
This means that to drive 48 kilometers Pat needs 4 liters of gas and to drive 132 kilometers she needs 11 liters of gas.

Work out the total cost of the bottles of orange squash Jill needs to buy.
The total cost of squash needed for the 50 people is £10
How to solve an equationJill makes orange juice for 50 people. Each person would need 2 full glasses, hence:
Total glasses of juice = 50 people * 2 glasses per person = 100 glasses
Each glass is 250 milliliters, hence:
Total volume of juice = 100 glasses * 250 ml per glass = 25000 ml
1000ml = 1l
25000 ml = 25000 ml * 1l per 1000ml = 25 liters
1 part of orange squash is mixed with 4 part of water, hence:
Amount of squash = (1/5) * 25 liters = 5 liters

find the coordinate of a triangle a(1,3) , b(2,5) and c(3,3) after being rotated about fixed point p(2,4) by 45 in clockwise direction and then translate (3,4) .
After the transformation point A will be at (5, 6.586), point B will be at (5.121, 7.121) and point C will be at (6.121, 5.121).
STEPS FOR FIND THE COORDINATEThe coordinates of a triangle after rotation and translation can be found using the following steps:
Rotation: To rotate a point (x, y) about a fixed point (a, b) by an angle θ (in this case, 45 degrees in the clockwise direction), you can use the following formulas to find the new coordinates:x' = (x - a) * cos(θ) - (y - b) * sin(θ) + a
y' = (x - a) * sin(θ) + (y - b) * cos(θ) + b
Translation: To translate a point (x, y) by a distance (dx, dy) in the x and y direction, you can use the following formulas to find the new coordinates:x' = x + dx
y' = y + dy
So for the first vertex of the triangle(1,3) after being rotated about fixed point p(2,4) by 45 in clockwise directionx' = (1 - 2) * cos(45) - (3 - 4) * sin(45) + 2 = -1.121 + 1.121 + 2 = 2.000
y' = (1 - 2) * sin(45) + (3 - 4) * cos(45) + 4 = -0.707 - 0.707 + 4 = 2.586
And after the translation (3,4) for point Ax' = 2 + 3 = 5
y' = 2.586 + 4 = 6.586
similarly for point B(2,5) will be (5.121,7.121)
and for point C(3,3) will be (6.121,5.121)
So after the transformation point A will be at (5, 6.586), point B will be at (5.121, 7.121) and point C will be at (6.121, 5.121)Learn more about coordinate of a triangle here:

It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

In the given parallelogram, the value of a is 40 and b is -10.
What is a parallelogram?A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.
Given a parallelogram ABCD
Since, two opposite angles of Parallelogram is equal
Thus, ∠ B = ∠ D and ∠ A = ∠ C
From above equations
3a + b = 110....(1)
Since, sum of all angles in quadrilateral is 360
Thus,
110 + 3a + b + 2(a - 3b) = 360
110 + 110 + 2(a -3b) = 360
2 (a - 3b) = 360 - 220 = 140
a- 3b = 70.....(2)
From equation 1 and equation 2
Multiply with 3 in equation 1 and then add with equation 2
9a + 3b + a - 3b = 330 + 70
10a = 400
