describe what would happen if you change the number of balls on the display, how would that change the number of balls on 6 display

Answers

Answer 1

Final answer:

If we modify the number of balls on a display it would alter the number of balls on the other displays based on an underlying mathematical rule or pattern.

Explanation:

The number of balls on the display could potentially represent a mathematical relationship or pattern. If we increase or decrease the number of balls on one display, it would change the number of balls on the other displays in a way that reflects this pattern.

For example, let's assume that the pattern is such that each display has twice the number of balls as the one before it. So if the first display has 1 ball, the second has 2, the third has 4, and so on. If you change the number of balls on the first display to 2, then the number of balls on the 6th display would increase according to the rule, and would become 2^6=64 instead of 1^6=32.

However, the relationship or pattern between the displays would need to be known in order to accurately predict how changing the number of balls on one display would affect the others.

The length of the base of a triangle is twice its height. If the area of the triangle is 64 square kilometers, find the height.

Answers

Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8

Final answer:

To find the height of the triangle with an area of 64 square kilometers and a base twice its height, we use the area formula: A = (1/2) × base × height, which leads us to determine that the height is 8 kilometers.

Explanation:

The question given involves finding the height of a triangle when the area is known and the relation between the base and height is given. Since the base is twice the height (b = 2h), and we know the formula for the area of a triangle is A = (1/2) × base × height, we can substitute the known area and the base-height relationship into this formula to solve for the height.

The area (A) is given as 64 square kilometers, which leads to the equation:

A = (1/2) × b × h = (1/2) × (2h) × h = h²,

Therefore, with A = 64 km², we obtain:

64 = h².

Taking the square root of both sides gives us the height (h):

h = √64 km = 8 km.

So the height of the triangle is 8 kilometers.

A conical cup is made from a circular piece of paper with radius 6 cm by cutting out a sector and joining the edges as shown below. Suppose θ = 5π/3.

Answers

The [tex]r[/tex], [tex]h[/tex], and 6 cm form a right triangle, so you find [tex]h[/tex] with the Pythagorean Theorem.

[tex]r^{2}+h^{2}=6^{2}[/tex]
We have [tex]r=5[/tex], so
[tex]5^{2}+h^{2}=6^{2}[/tex]
[tex]\rightarrow 25+h^{2}=36[/tex]
[tex]\rightarrow h^{2}=11[/tex]
[tex]\rightarrow h=\sqrt{11}[/tex]

Answer:

(a) 10π cm

(b) r = 5 cm

Step-by-step explanation:

(a) The surface of the opening the cup is circular in shape and a sector is cut from circle is calculate by formula,

C = r × θ

here, r = 6 cm

and θ = [tex]\frac{5\pi}{3}[/tex]

⇒ [tex]C = 6 \times \frac{5\pi}{3} = 10\pi[/tex]

(b) For finding the radius of the cup,

As the circumference of the circle is 10π

and we know that area of cone is calculate by formula, 2πr

⇒ 2πr = 10π

⇒ r = 5 cm

Radius = 5 cm

Thus, using Pythagoras theorem,

l² = h² + r²

⇒ h² = l² - r²

⇒ h² = 36 - 25

⇒ h = √11 cm

C - Suzanne makes wooden dolls. She made 2 in the morning and 2 in the afternoon. She did this for 4 days. How many dolls did she make?

A Danny's Problem
B Bobby's Problem
C Suzanne's Problem

Answers

The answer is A.

He ran for six (6) miles every day. 4 in the morning and 2 at night = 6 per day.

He did this for four (4) days. The way to figure this would be to go 6 * 4. This equals 24 miles.

Go back a few steps (punny!).

So days multiplied by how many miles he ran a day which is calculated by miles in morning added to miles at night.

days*(miles per morning + miles per night)

days=4
miles per morning=4
miles per night = 2

4 * (4+2)

Calculating this out....

4 * (4+2)

(4+2 = 6)

4 * 6 = 24.

So A is the answer.

Jim wants to build a rectangular parking lot along a busy street but only has 2,200 feet of fencing available. If no fencing is required along the street, find the maximum area of the parking lot.

Answers

The perimeter of the parking :
2 W + L = 2,200 ( there is no fence along the street )
L = 2200 - 2 W
The area of the parking is:
A = W x L = W ( 2,200 - 2 W ) = 2,200 W - 2 W²
A` = 2,200 - 4 W
2,200 - 4 W = 0
4 W = 2,200
W = 2,200 : 4 = 550 ft
L = 2,200 - 1,100 = 1,100 ft
The maximum area is:
A max = 1,100 x 550 = 605,000 ft²

Final answer:

The problem is an optimization problem in mathematics where one must use algebra and calculus to maximize the area of a rectangular parking lot with a given amount of fencing along three sides. By setting up a function for the area in terms of width and differentiating, the maximum area can be found.

Explanation:

The problem presented involves finding the maximum area of a rectangular parking lot given a certain amount of fencing, when one side of the rectangle requires no fencing. This is a classic optimization problem in mathematics which involves the use of algebra and calculus. By setting up a function for the area of the rectangle in terms of one variable and differentiating to find the maximum value, we can determine the solution.

Lets assume that the length of the lot that is along the busy street doesn't require fencing, and let the width of the lot be w and the length be l. Since fencing is only required for three sides, and we have 2,200 feet of fencing, the perimeter equation is 2w + l = 2,200. Solving for l, we get l = 2,200 - 2w. The area A of the parking lot will be given by the equation A = w * l. Substituting the expression for l into the area equation, we get A = w(2,200 - 2w) or A = 2,200w - 2w^2. To find the maximum area, we take the derivative of A with respect to w, set it to zero, and solve for w. Once the width is found, we can find the length using the perimeter equation and thus calculate the maximum area of the lot.

What type of simple machine is the crescent wrench

Answers

The crescent wrench is a type of lever, a simple machine that amplifies force to provide greater torque on fasteners with less input effort.

The crescent wrench is a type of simple machine, specifically it is a form of a lever. When you use a crescent wrench, you apply force to the handle, which then applies force to the object you are turning. The pivot point, or fulcrum, is the adjustable jaw which grips the nut or bolt. This allows the user to exert a greater torque on the fastener with less force than would be needed if just using one's hands.

Like other levers, the crescent wrench allows for a mechanical advantage, which is the ratio of output to input forces for any simple machine. By lengthening the handle of the wrench (the effort arm), we achieve a greater mechanical advantage, and thus, can apply more torque to the bolt or nut we are trying to turn.

A rectangular room is 1.5 times as long as it is wide, and its perimeter is 35 meters. find the dimesions of the room

Answers

Final answer:

The width of the room is 7 meters and the length is 10.5 meters.

Explanation:

To find the dimensions of the rectangular room, let's assume the width of the room is x meters. According to the given information, the length of the room is 1.5 times the width, so the length would be 1.5x meters.

The perimeter of a rectangle is calculated by adding twice the length to twice the width. So, we have the equation:

2x + 2(1.5x) = 35

Simplifying the equation, we get:

2x + 3x = 35

Combining like terms, we have:

5x = 35

Dividing both sides of the equation by 5, we find that x = 7.

Therefore, the width of the room is 7 meters and the length is 1.5 times the width, which is 1.5 * 7 = 10.5 meters.

Answers

There are total of 5 digits, of which we arrange 3 of them.
Therefore using permutations we can find total possible 3-number combinations.
5P3 = 5*4*3 = 60

To be greater than 600 means first digit must be 6. (1 possibility)
A number is even only if last digit is even, 2 or 4. (2 possibilities)
The 2nd digit then can only be 3,5, (2 or 4). (3 possibilities)
The total possible even 3-digit numbers greater than 600 is product of each digit's possibilities.
---> 1*3*2 = 6

Therefore probability is 6/60 = 1/10.

Use the method of cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis. xy = 9, x = 0, y = 9, y = 11

Answers

When integrating using shells, the first step is to plot the graph. I personally plotted it with the x and y axis switched, because it aids me in picturing the graph. The integral ranges from 9 to 11, since those are the limits from the two lines y = 9 and y = 11. The reason that these are the limits is because it is rotating around the x, not the y.
[tex] \int\limits^{11}_{9}[/tex]
Now that you have the limits of the integral, you have to find what goes inside it.
Because you are integrating using shells, you need to remember to include the [tex]2\pi y[/tex] Again, there is a y here instead of an x, because you are rotating around the x axis. Then you just need to input the function f(y). If you look at the graph that you (hopefully) plotted, you can see that this function ranges between the y axis and the curve [tex]f(y) = \frac{9}{y}[/tex]. Put together the pieces, and you have the integral
[tex] \int\limits^{11}_{9} {2 \pi y*f(y)} \, dy [/tex]
After substituting in [tex]f(y) = \frac{9}{y}[/tex], you get
[tex] \int\limits^{11}_{9} {2 \pi y*\frac{9}{y}} \, dy [/tex]
Simplified, this is [tex] 18\pi\int\limits^{11}_{9} \, dy [/tex]
Integrating, we get [tex] 18\pi * 2[/tex]

Therefore, the solution is [tex] 36 \pi [/tex]

Note: I didn't spend very much time reviewing these integrals, so I may be incorrect.

Final answer:

The volume of the solid obtained by rotating the region bounded by the curves about the x-axis is found using cylindrical shells, resulting in a total volume of 36π cubic units.

Explanation:

To find the volume of the solid obtained by rotating the region bounded by the curves xy = 9, x = 0, y = 9, and y = 11 about the x-axis, we will utilize the method of cylindrical shells. The curves define a region in the xy-plane which, when rotated about the x-axis, forms a solid with varying radii. To apply the method, we first need to express the variable x in terms of y from xy = 9 to obtain x = 9/y.

Next, the volume of a representative cylindrical shell with thickness dy and height x = 9/y is given by the circumference of the shell (2πy) times the height (9/y) times the thickness (dy). This leads to the volume element dV = 2πy(9/y)dy = 18πdy. Integrating this volume element with respect to y between the limits 9 and 11 yields the total volume.

Using the integral calculus, the volume V is:
V = ∫911 18π dy = 18π [y]∫911 = 18π(11 - 9) = 36π cubic units.

Thus, the volume of the cylinder is 36π cubic units.
