GEOMETRY The combined volume of a cube and a cylinder is 1000 cubic inches. If the height of the cylinder is
twice the radius and the side of the cube is four times the radius, find the radius of the cylinder to the nearest tenth
of an inch
The radius of the cylinder with a combined volume of 1000 cubic inches is 2.4 inch
What is an equation?An equation consists of numbers and variables linked together by mathematical operations to form an expression.
Let r represent the radius of the cylinder/cone.
For the cylinder:
Volume = π * radius² * height
but height is twice the radius, height = 2r, hence:
Volume = π * r² * 2r = 2πr³
For the cube:
Volume = side³
but side is four times the radius, side = 4r, hence:
Volume = (4r)³ = 64r³
The combined volume of a cube and a cylinder is 1000 cubic inches, hence:
1000 = 2πr³ + 64r³
r³(2π + 64) = 1000
r³ = 1000/(2π + 64)
r³ = 14.228
r = 2.4 inch
The radius is 2.4 inch

The drama club earned $1040 from a production. A total of 64 adult tickets and 132 student tickets were sold. An adult ticket costs twice as much as a student ticket. What is the price of each type of ticket sold? Use x for adult tickets and y for student tickets.
Answer: $8
Step-by-step explanation:
one adult ticket costs twice as much as one student ticket so
cost of 1 student ticket=x
cost of one adult ticket=2x
total money made=1040
adults+students=1040 so
64(2x)+132(x)=1040
128x+132x=1040
260x=1040
divide both sides by 260
x=4
1 student ticket=$4
1 adult ticket=2x=2(4)=$8

Higher Order Thinking Lauren has a stamp collection. She gives Kristen 12 stamps and Ethan 15 stamps. Lauren has 22 stamps left. How many stamps did she have at the start?
Answer: 49 Stamps
Step-by-step explanation:
If Lauren gave Kristen and Ethan 12 stamps and 15 stamps respectively, that means that she gave them a total of 27 stamps. This leaves her with 22 stamps left. In order to find the number of stamps she had at the start, add the stamps she gave away to the stamps she had left at the end. So,
15 stamps + 12 stamps + 22 stamps = 49 stamps total at the start
Lauren had 49 stamps in the beginning. Since she gives Kristen 12 stamps, and Ethan 15 stamps, we can add both amounts to assume the total number of stamps she gave away. 15+12=27, so she gave away 27 stamps. Lauren was left with 22 stamps. We can add 22 to 27 to find out how many stamps she had in all. 27+22=49. Therefore, we can come to the conclusion that Lauren had 49 stamps at the start.

The amount of snow that falls from time t = 0 to time t = 5 hours is 20(1-e^(-0.5)) inches.
What is integration ?
Integration is the process of finding an antiderivative of a function. An antiderivative of a function is a function whose derivative is equal to the original function. In other words, integration is the reverse process of differentiation. The process of integration can be thought of as the summing of an infinite number of infinitesimal "slices" of the function being integrated, over a given interval. The symbol ∫ is used to denote integration.
The amount of snow that falls between time t = 0 and time t = 5 hours can be found by evaluating the definite integral of the rate of snowfall with respect to time over the interval [0, 5].
∫[0,5] 2e^(-0.1t) dt
The antiderivative of 2e^(-0.1t) with respect to t is -20e^(-0.1t)
Therefore, the definite integral is
-20e^(-0.15) - (-20e^(-0.10))
= -20e^(-0.5) + 20 = 20(1-e^(-0.5))
Therefore, the amount of snow that falls from time t = 0 to time t = 5 hours is 20(1-e^(-0.5)) inches.

In the ΔWXY, with the incenter of the triangle being Z.
1. The measure of m∠WYZ = 43°.
2. The measure of m∠WXY = 66°.
3. The measure of m∠YWX = 28°.
4. The measure of m∠ZWX = 14°.
What is an incenter?
The intersection of the triangle's three interior angle bisectors forms the triangle's incenter. Due to the junction point of the central axis being the centre of the triangle's inscribed circle, this point is equally spaced from the sides of a triangle.
In ΔWXY, the incenter of the triangle is Z.
This means that ∠W, ∠Y and ∠X are equally bisected angles.
It is given that the measurement of ∠WYX = 86° and ∠WXZ = 33°
1. The measure of angle ∠WYZ.
The angle ∠WYX is bisected by the line segment YZ.
It forms two angles ∠WYZ and ∠XYZ.
So, the measurement of ∠WYZ = ∠WYX/2
∠WYZ = 86°/2
∠WYZ = 43°
Therefore, the measurement of ∠WYZ = 43°.
2. The measure of angle ∠WXY.
The angle ∠WXY is bisected by the line segment XZ.
It forms two angles ∠WXZ and ∠ZXY.
The measurement of angle ∠WXZ = 33°.
So, the measurement of ∠WXY = ∠WXZ × 2
∠WXY = 33° × 2
∠WXY = 66°
Therefore, the measurement of ∠WXY = 66°.
3. The measure of angle ∠YWX.
According to the properties of the triangle, the sum of three angles of triangle is 180°.
So, the equation will be -
∠YWX + ∠WXY + ∠XYW = 180°
∠YWX + 66° + 86° = 180°
∠YWX + 152° = 180°
∠YWX = 180° - 152°
∠YWX = 28°
Therefore, the measurement of ∠YWX = 28°.
4. The measure of angle ∠ZWX.
The angle ∠YWX is bisected by the line segment WZ.
It forms two angles ∠YWZ and ∠ZWX.
So, the measurement of ∠ZWX = ∠YWX/2
∠ZWX = 28°/2
∠ZWX = 14°
Therefore, the measurement of ∠ZWX = 14°.

The separation between endpoints A and B is the length of this line segment. An area or portion of a line with two endpoints is known as a line segment. A line segment has a set length as opposed to a line. Both metric measurements, such as millimeters and centimeters, as well as conventional units, such as feet or inches, can be used to measure the length of a line segment. The length of one line segment in comparison to the other when there are two can be determined just by glancing at them. The line segment CD is longer than AB, as can be seen.
given
ST = 2y + 9 RS = 7y + 3
RT = 14y - 8
S lies between R and T, hence we can deduce that:

The metre, the fundamental linear unit in the metric system, has largely replaced the foot, with its multiples and subdivisions, in most nations and in all scientific applications. In the United States, the definition of a foot as exactly 30.48 cm went into effect in 1959.
We know that
1 feet = 12 inches
So, 5 feet 8 inches = 5[tex]\frac{2}{3}[/tex] feet
Now, lets find the shadow of tree
5[tex]\frac{2}{3}[/tex]/2 = 321/x
x = 113[tex]\frac{5}{11}[/tex]
x = 113.29
Thus, the tree's shadow at the same time of day was 113.29 foot long

The graph at the right illustrates the rate at which Dave and Joe are saving money.
a. Estimate the solution to the system.
b. Explain what this means in the context of
the saving money scenario.
This problem can be solved using a system of equations.
What is the system of equations?
A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and graphical solutions are possible for these equations. The point of intersection of two lines represents the system of equations' solution.
Line 1
Taking two points on this line (0,300) and (4,450)
Equation of line y = mx+c
m = [tex]\frac{450 - 300}{4 - 0}[/tex] = 37.5
y = 37.5x + c
Substituting (0,300) in the above equation
300 = 37.5 * 0 + c
c = 300
Line equation y = 37.5x + 300
Line 2
Taking two points on this line (0,400) and (5,500)
m = [tex]\frac{500 - 400}{5 - 0}[/tex] = 20
y = 20x + c
Substituting (0,400) in the above equation
400 = 250* 0 + c
c = 400
Line equation y = 20x + 400
a) The solution of the system is when both lines coincide
37.5 x + 300 = 20x + 400
17.5 x = 100
x = 5.7
y = 20 * 5.7 + 400 = 514
Therefore the solution of the system is ( 5.7 , 514)
b) In terms of saving money scenario. This means that Dave and Joe have the same amount of savings at this point.
Therefore these are the solutions to the above system of equations.

For which interval is the function constant?
(−∞,−6)
(2,∞)
(−6,0)
(0,2)
The function is constant in the interval (-6 to 0).
The correct option is (C).
What is a Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
If the value of one of the variables does not alter the value of the other, the function is said to be constant.
As we can see, the function is constant in the range from x=-6 to 0, because the value of y in the function does not change as the value of x changes (-6 to 0).
