The height of the can of cylinder shape is 9.14 cm.
What is a cylinder?
In mathematics, a cylinder is a three-dimensional solid that maintains two parallel bases separated by a curved surface at a specific distance. These bases frequently have a circular shape (like a circle), and an axis connects their respective centres.
We are given the diameter as 4 cm.
So, the radius is 2cm.
Also, it is given that the surface area of the can is 140 square centimeters.
So, using the surface area of cylinder, we get
⇒Area = 2πr (h + r)
⇒140 = 2π * 2 (h + 2)
⇒140 = 4π (h + 2)
⇒140 = 4 * 3.14 * (h + 2)
⇒140 = 12.56 * (h + 2)
⇒11.14 = h + 2
⇒h = 9.14
Hence, the height of the can of cylinder shape is 9.14 cm.

The diameter of a circle is 10 3/4 inches.
What is the radius, r, of the circle?
Enter your answer as a mixed number in simplest form by filling in the boxes.
Answers
Answer: The radius of the circle is 5 3/8 inches.
Step-by-step explanation:
The radius of the circle is half of the diameter. We can start by converting the mixed number diameter to an improper fraction:
10 3/4 = (10 × 4 + 3)/4 = 43/4
So, the diameter of the circle is 43/4 inches. The radius is half of this, which we can find by dividing by 2:
r = (43/4) ÷ 2 = 43/8
To simplify the fraction, we can divide the numerator and denominator by their greatest common factor (GCF), which is 1:
r = 43/8 = 5 3/8
Therefore, the radius of the circle is 5 3/8 inches.
Answer:5 3/4
Step-by-step explanation:
10 3/4 * 1/2
1/2 * 43/4 = 43/8

Answers
Answer:
b. The method used to calculate the confidence interval has a 90% chance of producing an interval that captures the population mean number of annual pass holders in the park on any given day.
Step-by-step explanation:
The confidence interval calculated from the sample at a particular confidence level, gives a certain percentage of confidence based on the confidence level that the true mean of the population exists within the confidence interval Calculated.
For the scenario above, we can say that there is a 90% chance that the population mean number of annual pass holders in the park on a given day is within the interval (35, 51)

The sales price should be $75.00 for the first two quarters and $82.50 for the last two quarters.
Prepare the Production Budget assuming: 1. The company believes it can meet future sales needs with an ending inventory of 25% of the next quarter, for the first two quarters, and 35% of the next quarter, for the last two quarters. 2.

Sales Price $75.00 $75.00 $ 82.50 $82.50
Sales $ 600,000 720,000 594000 825,000
We calculate the sales volume by applying the given percent to the sales units for each quarter. Then multiply it with the sales price to get the sales budget.
Production Budget

We find the production budget units by adding the desired ending inventory and subtracting the opening inventory from the sales units calculated above.

The second one includes 3 small tiers and 5 large tiers, which is enough servings for 316 guests. How many guests does each size of tier serve?
A small tier will serve guests and a large tier will serve guests.
Answers
Answer:
small tier: 22large tier: 50Step-by-step explanation:
If cakes of 4 small and 4 large tiers serve 288 guests, and 3 small and 5 large tiers serve 316 guests, you want to know the number of guests served by a tier of each size.
SetupLet 's' and 'l' represent the numbers of guests served by small and large cake tiers, respectively. The first cake serves ...
4s +4l = 288
And the second cake serves ...
3s +5l = 316
SolutionSubtracting 3/4 of the first equation from the second gives ...
(3x +5l) -3/4(4s +4l) = (316) -3/4(288)
2l = 100
l = 50
4s +4(50) = 288 . . . substitute for l in the first equation
4s = 88 . . . . . . . . . . subtract 200
s = 22 . . . . . . . divide by 4
A small tier will serve 22 guests; a large tier will serve 50 guests.
JKL is an isosceles triangle. Jk=jl. JK = 2x+3, and KL=10-4x what is the perimeter of jkl
Answers
The perimeter of an isosceles triangle JKL will be 16.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
JKL is an isosceles triangle.
And, JK = JL
Measure of JK = 2x + 3 and KL = 10 - 4x
Now,
Since, JKL is an isosceles triangle.
And, JK = JL
Hence, Measure of JK = Measure of JL
So, The perimeter of a triangle = JK + JL + KL
Substitute all the values, we get;
The perimeter of a triangle = (2x + 3) + (2x + 3) + (10 - 4x)
= 2x + 3 + 2x + 3 + 10 - 4x
= 4x + 6 + 10 - 4x
= 16
Thus, The perimeter of an isosceles triangle JKL will be 16.

Prove that 3-2√5 is irrational.
Answers
Our assumption that 3-2√5 is a rational number is false, and hence it is an irrational number.
Let's prove that 3-2√5 is irrational. Let's suppose that 3-2√5 is a rational number, it means it can be represented as a ratio of two integers. Thus, we can write
3-2√5 = p/q, where p and q are integers with no common factors. Assume q≠0. Rearranging, we get:
3 = (2√5)q + p
Now, squaring both sides we get:
9 = 20q2 + 2pq√5 + p2(5)
Since p and q are integers, we have that 5q2 and p2(5) are both multiples of 5, and hence their difference is also a multiple of 5. Thus, 5 divides 9-p2(5) which means that 5 also divides (3-p)(3+p). Since 5 is prime and it divides the product of (3-p)(3+p), it must divide 3-p or 3+p (or both).
Hence, either 3-p or 3+p is divisible by 5. However, the possible values of p are ...,-3,-2,-1,0,1,2,3,... and thus p+3 is also in this set. Since 5 divides p+3, it must be the case that p+3 = 5n for some integer n. Hence p = 5n - 3. Now we have:
3 = (2√5)q + p = (2√5)q + (5n - 3)
Rearranging, we get:
(2√5)q = 6 - 5n
Since 2√5 is irrational, we have a contradiction because we have found that 2√5 is a rational number which is impossible.
Therefore, our assumption that 3-2√5 is a rational number is false, and hence it is an irrational number.

Find the selling price, Cost to store:$120 Markup:60%
Answers
The selling price for the item would be $192.
To find the selling price, we need to consider the cost to store and the markup percentage. The markup percentage is 60%, which means the selling price will be 60% higher than the cost to store.
First, we calculate the markup amount by multiplying the cost to store by the markup percentage:
Markup amount = Cost to store * Markup percentage/100
= $120 * 60/100
= $72
Next, we add the markup amount to the cost to store to get the selling price:
Selling price = Cost to store + Markup amount
= $120 + $72
= $192
The selling price is determined by adding the markup amount, which is calculated by multiplying the cost to store by the markup percentage, to the cost to store itself. In this case, with a cost to store of $120 and a markup of 60%, the selling price would be $192.

a 13 foot ladder is leaning against the side of a house when its base starts to slide away. by the time the base is 12 feet from the house, the base is moving at a rate of 5 feet per second.
Answers
If the base of the ladder is moving at 5 ft/s , then the speed of top of the ladder is 12ft/s .
Pythagoras Theorem states that the relation between the square of the longest side is equal to the squares of the other two sides .
the length of the ladder (L) = 13 ft ;
the rate of movement of the base (dx/dt) = 5 m/s ;
By Pythagoras Theorem ,
13 = x + y ....eqn(1)
So , y = √(169 - x)
putting x = 12 , we get ;
y = √(169 - 144) = 5 ft ;
Differentiating eqn(1) , w.r.t. "x" ,
we get ;
0 = 2x(dx/dt) + 2y(dy/dt)
So , dy/dt = (-x/y)(dx/dt)
putting the values ,
we get ;
dy/dt = -12 ft/s .
Therefore , the ladder is sliding down the wall at 12 ft/s .
