The height of the cup that can be made from the least amount of paper is 17 cm.

A cone-shaped paper cup is to hold 100 cubic cm of water. Find the height and the radius of the cup that can be made from the least amount of paper.

Use the volume of a cone formula: (1/3)*pi*r^2*h = V; to find h in terms of r.

(1/3)*pi*r^2*h = 100

multiply equation 3 to get rid of the denominator

pi*r^2*h = 300

h = 300/(pi * r^2)

:

Using the surface area equation: SA = pi*r^2 + (pi*r*L), find L using r and h

L = \(\sqrt{h^{2} +r^{2} }\)

Substitute above for L in the SA equation

:

\(SA = \pi r^{2} + \pi r\sqrt{\frac{300}{\pi r^{2} } + r^{2} }\)

:

Using this equation in my TI83, the graph showed the minimum radius to occur at appox 2.37 cm

:

Find the height using this value:

h = 17 cm

Check solution by finding the volume

V = (1/3) * pi * 2.37^2 * 17

V = 99.994 ~ 100 cm

Hence , the height of the cup that can be made from the least amount of paper is 17 cm.

The volume of the ring-shaped solid that remains after drilling is 3961.73cm³.

The radius of the cylindrical drill is 5cm and the radius of the sphere is found to be 10cm.

After drilling,

The radius of the of the sphere will act as a hypotenuse to the triangle where the base is the radius of the cylinder and the perpendicular is the height of the cylinder.

So, we can say,

Height H of cylinder = √(10² - 5²)

Height H of cylinder = 8.66 cm.

The volume V of the ring shape remaining,

V = Volume of sphere - volume of cylinder

V = 4/3πR³ - 1/3πr²H

R is the radius of sphere and r is the radius of cylinder,

Putting values,

V = 4/3π(10)³ - 1/3π(5)²8.66

V = 3961.73 cm³.

So, the volume that remains is 3961.73cm³.

If Caron gives $75, he will get $21 as a change, when he buys a constellation display.

To estimate the amount of change Caron will get back, we need to calculate the total cost of the two-sided tape and the star stickers. The two-sided tape costs $12 and Caron wants to buy 3 packs of star stickers which cost $14 each, so the total cost of the star stickers is 3 * $14 = $42. The total cost of both the two-sided tape and the star stickers is $12 + $42 = $54.

If Caron gives $75, he will get $75 - $54 = $21 as change. This is a rough estimate of the amount of change Caron will get back, and it's always a good idea to have a little extra money in case the actual cost is slightly higher.

Given:

Selling price of each pound of strawberries = $2.50

Selling price of each pound of raspberries = $3.75

Total quantity = 65 pounds

Total sales = $225

To find:

The number of pounds of strawberries sold, and the number of pounds of raspberries sold graphically.

Solution:

Let x be the number of pounds of strawberries and y be the number of pounds of raspberries sold.

According to the question,

Total quantity : \(x+y=65\)      ...(i)

Total sales : \(2.50x+3.75y=225\)      ...(ii)

Table of values for equation (i) is

x          y

0        65

65       0

Table of values for equation (ii) is

x          y

0        60

90       0

Plot these point on coordinate plane and connect them by straight lines as shown in the below graph.

From the graph it is clear that both lines intersect each other at (15,50). So,

\(x=15, y=50\)

Therefore, the number of pounds of strawberries sold is 15 and the number of pounds of raspberries sold is 50.

The number of pounds of strawberries sold and the number of pounds of raspberries sold is 15 and 50

here we assume the strawberries be x

and, the raspberries be y

Now

x + y = 65

It can be written as y = 65 - x

2.50x + 3.75y = 225

From the graph we can say that it should be 15 and 50.

Step-by-step explanation:

Using the congruent theorem,

a. ∠XBC will be equal to ∠AXY as the lines are parallel to each other for which the angles are corresponding to each other.

b. ∠BXC = 70°

Equal amounts of angles are referred to as congruent angles. As a result, congruent angles are those whose measures are the same. They can be found anywhere, including in isosceles triangles, equilateral triangles, and situations where a transversal joins two parallel lines.

Here in the question,

∠AXY = 55°

XY ║ BD

XB = XC

a.

So, from the figure:

∠XBC will be equal to ∠AXY as the lines are parallel to each other for which the angles are corresponding to each other.

So, ∠XBC = ∠AXY =55°

b.

Now,

In ΔXBC, XB = XC

So, ∠XBC = ∠XCB = 55°.

As per angles in a triangle,

∠XBC + ∠XCB + ∠BXC = 180°

⇒ ∠BXC = 180 - 55 - 55

⇒ ∠BXC = 70°

Transitive property of segment congruence states that if two segments are congruent to the same segment, then they are congruent to each other. Mathematically, it can be written as, if AB ≅ JK and JK ≅ ST, then AB ≅ ST.

In the given problem, it is given that AB is congruent to JK and JK is congruent to ST. Therefore, it can be concluded that AB is congruent to ST because of the transitive property of segment congruence, i.e., AB ≅ JK ≅ ST ⇒ AB ≅ ST.Let’s have a brief discussion on how transitive property of segment congruence holds true.

It is based on the fact that segments that are equal to the same segment are equal to each other. Therefore, if AB ≅ JK, then AB and JK have the same length. Similarly, if JK ≅ ST, then JK and ST have the same length. Now, since AB and JK have the same length, and JK and ST also have the same length, it can be concluded that AB and ST are also equal. Hence, AB ≅ ST is proved using the transitive property of segment congruence.

Answer: That is incorrect because the garden will be 17 ft by 17 ft meaning it will be 289 square feet.

Step-by-step explanation:

The relationship between the base of the power, the expression f(x+1)/f(x), and the common ratio of the corresponding geometric sequence is that they are all equal.

To see this, let's first write out the function f(x) and f(x+1):

f(x) = a× \(b^{x}\)

f(x+1) = a×\(b^{x+1}\) = a×\(b^{x}\) × b

Now, let's find the expression f(x+1)/f(x):

f(x+1)/f(x) = (a×b^x × b) / (a×\(b^{x}\))

= b

So, the expression f(x+1)/f(x) is equal to the base of the power, b.

Next, let's consider the corresponding geometric sequence. A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a constant, called the common ratio. In this case, the common ratio is the base of the power, b.

So, the relationship between the base of the power, the expression f(x+1)/f(x), and the common ratio of the corresponding geometric sequence is that they are all equal to the base of the power, b.
