If a baseball player hits 10 home runs in the first 45 game, at the same rate how many home runs can he expect to hit during the 162 game season
Using proportions, it is found that he can be expected to hit 36 home runs during the 162 game season.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the player hits 10 home runs in 45 games, hence the proportion is:
p = 10/45.
Then, in 162 games, the amount is:
HR = 10/45 x 162 = 36.

Given the mark up of all furniture in the store, the price that the manager should charge for the couch that just arrived is $163.85.
How much should the manager charge for the couch that just arrived?Given that;
Purchase price = $113.00 marks up = 45%Selling price = ?First, we determine the mark price.
Since the Furniture Store marks up all furniture by 45%.
Mark up price = mark up × purchase price
Mark up price = 45% × $113.00
Mark up price = 0.45 × $113.00
Mark up price = $50.85
Now, the selling price will be;
Selling price = Purchase price + mark up price
Selling price = $113.00 + $50.85
Selling price = $163.85

Answer:
[tex]\text{Perimeter of sector = 43.6 (Rounded to the nearest tenth.)}[/tex]
Step-by-step explanation:

Is 9 a solution to the equation 21=3p-5? Show work
Answer:
No
Step-by-step explanation:
21 = 3p - 5
Step 1 : Add 5 on both sides
21 + 5 = 3p
26 = 3p
3p = 26
Step 2 : Divide 3 on both sides
p = 26/3
Hence, the solution of the given equation is 26/3, not 9.
A coffee table is on sale for 20% off the original price of $115. If there is 7.5% sales tax, what is the final price of the coffee table?
Answer:
The final price for the coffee table is $98.9.
Step-by-step explanation:
1. First, is to convert the percentage to decimal form
We can do this by changing 7.5% to decimal number by dividing 7.5 by 100, we get:
\frac{7.5}{100}
100
7.5
= 0.0750.075
2. Then multiply 0.075 to the original price of $115
0.075(115) = 8.625
Then, add 8.625 to the original price of $115, we get:
115 + 8.625 = $123.625
3. After this, we subtract the 20% discount to $123.625
We can do this by converting 20% to decimal form, we get:
\frac{20}{100}
100
20
= 0.20.2
Then, multiply $123.625 by 0.2, we get:
123.625(0.2) = $24.725
4. Then subtract 24.725 from $123.625, we get:
123.625 -123.625−24.725 = $98.9
Final price of the table coffee which is on sale by 20% with a sales tax of 7.5% is $98.9.

Part 1
V = pi*r^2*h .... volume of a cylinder
250 = pi*r^2*h
h = 250/(pi*r^2)
Plug this into the surface area of a cylinder equation
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*pi*r^2 + 2*pi*r*( 250/(pi*r^2) )
SA = 2*pi*r^2 + 500/r
Now replace every copy of r with x to get this function
f(x) = 2*pi*x^2 + 500/x
x = radius
y = f(x) = surface area
Next we'll use Desmos to graph this function. See the screenshot below. It produces some kind of curve that has two pieces to it. We'll only focus on the curve where x > 0 and y > 0. It makes no sense to have a negative radius, and we cannot have a negative surface area either.
Click on the lowest point of the parabolic looking shaped piece (it's not really a parabola, but we'll imagine that it is for the sake of simplicity).
The coordinates of that local min point will show up and they are (3.414, 219.689)
We have (x,y) = (3.414, 219.689) lead to r = 3.414 and SA = 219.689
This means that a radius of approximately r = 3.414 cm leads to the smallest surface area of approximately 219.689 square cm. This is when the amount of material is minimized.
Use this value of r to find h
h = 250/(pi*r^2)
h = 250/(pi*3.414^2)
h = 6.828
Desmos not only graphs, but it is also a standard calculator. The calculation is also shown in the screenshot.
Answer: This can has a radius of roughly 3.414 cm and height 6.828 cm.=============================================================
Part 2
Find the three side lengths of each triangle. So you should have 6 sides total. Then divide the corresponding sides to see if you get the same ratio. If so, then the triangles are similar by the side side side (SSS) similarity theorem. Another method is to find the angle between two sides and use the SAS (side angle side) similarity theorem. This is when the two pairs of sides form the same ratio, and the angles mentioned are congruent to each other. The angles must be between the sides used.A proportion can be used to solve equations based on similar polygons. For example, we could have the proportion x/2 = 30/10 which solves to x = 6.The first step is to multiply the two numbers. Then apply the square root to them. Example: The geometric mean of 4 and 9 is 6 because [tex]\sqrt{4*9} = \sqrt{36} = 6[/tex]A parallelogram has a base of 16 centimeters and a height of 12 centimeters. What is the area of the parallelogram?
I think it's 192, am I correct?
Answer:
Correct (192)
Step-by-step explanation:
The formula for a parallelogram's area is just base times height. 16x12 is equal to 192, so you are correct.
A parallelogram can be:
The square, which has all its sides of equal length, and all its angles are right angles. The rhombus, which has all sides of equal length, and only two pairs of congruent angles. The rectangle, which has only its opposite sides of equal length, and all its angles are right angles.Therefore we calculate the rectangle of a square, which is a parallelogram.
To start solving, we obtain the following data:
Area = 16cmHeight = 12cmArea = ? ===> (It is the result that we are going to obtain)The formula to calculate the area is:
[tex]\bf{a=b*h }[/tex]
To calculate the area, multiply the base by the height (which is represented in "h")
We clear formula, calculate the area:
[tex]\bf{A=(16 \ cm)(12 \ cm) \ \ \ ==== > \ Multiply }[/tex]
[tex]\bf{A=192 \ cm^{2} }[/tex]
Answer: The area of the parallelogram is 192 cm2. So if you're right, it was a rectangle.

---Find a common denominator
6/8 + -5/8
---Simplify
1/8
Hope this helps!
Answer:
3/4 + -5/8 = 1/8
Step-by-step explanation:
When adding fractions, you always need to find a common denominator. 4 and 8 share a common denominator of 8.
You multiply 3/4 by 2/2 and get 6/8.
When adding negative numbers, it is the same as subtracting.
6/8 + (-5/8) =
