Edges: 37
Faces: 25
Vertices: ?
Answer:
Step-by-step explanation:
Comment
The formula that relates edges faces and vertices is F + V = E + 2
Givens
Edges (E): 37
Faces (F) = 25
Vertices: x
Solution
25 + x = 37 + 2 Subtract 25 from both sides.
25-25 +x= 37 - 25 + 2 Combine
x = 12 + 2
x = 14
Answer: The vertices = 14

A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 35 ft long and 22Ft wide. Find the area of the garden. Do not round any intermediate steps. Round your final answer to the nearest hundredth and be sure to include the correct unit.
Answer:
Step-by-step explanation:
Area of rectangle: 35*22=770
Area of semi circle: 1/2pi(11)^2=60.5 pi
Area of garden 770+60.5 pi or 959.97 ft squared if pi =3.14
What is the volume of the following rectangular prism? 1 3/4 units
1/2 units
7/8 or 0.88
Explanation :-Just recall the formula for the volume of a prism: area of the base times its height. Now, is common to associate the base of a prism to the side which serves as a ‘‘base’’, i.e., the one in the bottom from our perspective.
This formula is right, but not quite precise. A better formulation for the formula would be: ‘‘the volume of a rectangular prism is equal to the area of a side times its relative height’’. Notice that we only need to rotate a prism to have a different side as a basis.
In the figure we have that the area of the green side is 1/2, and its relative height is 1 3/4. Thus, its volume is
Solution :-V=(1/2)*(1 3/4) = 7/8 = 13.5
Padma has room to line up 8 figurines in a display case how many different ways can she arrange the figurines in the display case? Enter your answer in the box
Answer:
it can be arranged in 40320 ways
Step-by-step explanation:
this is simply permutation,
so the ways of arrangement = 8!
=8×7×6×5×4×3×2×1
=40320
please mark brainliest:)
There are 40,320 different ways for Padma to arrange the 8 figurines in the display case.
What is the permutation?The permutation is defined as considered an ordered combination.
To determine the number of different ways Padma can arrange the 8 figurines in the display case, we can use the concept of permutations.
The number of permutations of n objects taken r at a time is given by the formula:
P(n, r) = n! / (n - r)!
In this case, Padma has 8 figurines, and she wants to arrange all of them in the display case, so r = 8.
P(8, 8) = 8! / (8 - 8)!
Simplifying:
8! / 0! = 8!
Calculating 8! (8 factorial):
8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40,320
Therefore, there are 40,320 different ways for Padma to arrange the 8 figurines in the display case.

The population of a small town was 10,800 in 2002. Since then the population has decreased at a rate of 2.5% each year. Write an exponential function to model the situation then find the population of 2020
Answer:
See below
Step-by-step explanation:
A 2.5 % decrease means 97.5 % remains (.975)
population = 10800 ( .975) ^n where n = years past 2002
in 2020 n = 18
10800 (.975)^18 = 6847 people

The answer is (5/2, 4/3)
Answer:
C. (5/2, 4/3)
Step-by-step explanation:
The system of equations that are given are:
[tex]3x + 5y = 14[/tex][tex]6x - 4y = 9[/tex]To solve, let's use the substitution method.
Note: The substitution method for solving two-order systems involves solving one equation using the terms of the other equation.See Below:
So solving by substitution:
// Solve equation [2] for the variable x
[2] 6x = 4y + 9 [2] x = 2y/3 + 3/2// Plug this in for variable x in equation [1]
[1] 3•(2y/3+3/2) + 5y = 14 [1] 7y = 19/2 [1] 14y = 19// Solve equation [1] for the variable y
[1] 14y = 19 [1] y = 19/14// By now we know this much :
x = 2y/3+3/2 y = 19/14// Use the y value to solve for x
x = (2/3)(19/14)+3/2 = 101/42Therefore, the solution is:
[tex]{x,y} =\frac{101}{42} ,\frac{19}{14}[/tex]

A particular fruit's weights are normally distributed, with a mean of 615 grams and a standard deviation of 10 grams.
The heaviest 10% of fruits weigh more than how many grams?
Give your answer to the nearest 0.1 gram.
The heaviest 10% of fruits weigh more than 814.79 grams.
The problem setup implies that the weight of this fruit is a random variable when it says a particular fruit's weights are normally distributed.
What are the formula weights are normally distributed?Define X = Random Variable of the fruit's weight
[tex]X \sim N(mean = 760, standard deviation = 39)[/tex]
We want to find the specific gram value for which 8% of the fruits are heavier
The 92nd percentile of X's normal distribution
[tex]Solve for x: Pr( X < x ) = Normal( 760, 39 ) CDF = .92[/tex]
Standardizing we obtain
[tex]Pr( [X - 760]/39 < [x - 760]/39 ) = Pr( Z < [x - 760]/39 ) = .92,[/tex]
where Z is a standard normal random variable
[tex]Pr( Z < [x - 760]/39 ) = Standard \ Normal \ CDF( [x - 760]/39 )[/tex]
==> Set this equal to .92:
[tex]Standard \ Normal \ CDF( [x - 760]/39 ) = .92[/tex]
Then, from the standard normal table:
[tex][x - 760]/39 = Inverse Standard Normal[/tex]
[tex]CDF( .92 ) = 1.405[/tex]
Use algebra to solve for x:
[tex]x = 39 * 1.405 + 760 = 814.795[/tex]
Therefore the heaviest 10% of fruits weigh more than 814.79 grams.
