What is area of rectangle?Area of rectangle is the product of its sides

What is area of circle?The area of a circle is pi times the radius squared (A = π r²).
What is circumference of circle?The circumference of a circle is defined as the linear distance around it.
( C= 2πr)
The can of red bull is in shape of cylinder.
If we open the cylinder it will have two circular surfaces( at bottom and top) and one rectangular sheet.
Like the given figure given.
The can is 6.5 inches tall and has a diameter of about 2.5 inches.
It shows that the two circle will have the diameter 2.5 inches.
d= 2.5 inch
= 0.208 ft
radius, r= [tex]\frac{d}{2}[/tex]
r= [tex]\frac{0.208}{2}[/tex]
r= 0.104 ft
To get the length of the rectangle , we have to calculate the circumference of the circle.Circumference of the circle be,
= 2πr
= 2 x 3.14 x 0.104
= 0.653 ft
The rectangular sheet will have,
length= 0.653 ft, breadth= 6.5 inches = 0.541 ft
Now, area of rectangular sheet be,= length x breadth
= 0.653 x 0.541
=[tex]0.3532 ft^{2}[/tex]
Area of 2 circle( top and bottom of can) be,= 2 x π[tex]r^{2}[/tex]
= 2 x 3.14 x 0.104 x 0.104
= 6.28 x 0.010816
= 0.0679 [tex]ft^{2}[/tex]
Total area of can be,= Area of rectangular sheet + Area of 2 circle( top and bottom of can)
= 0.3532 + 0.0679
= 0.4211 [tex]ft^{2}[/tex]
Now, we have the wall of dimensions
length= 9 ft, breadth= 20 ft
Area of wall be,= length x breadth
=9 x 20
= 180 [tex]ft^{2}[/tex]
Number of cans required to cover the whole wall be,=[tex]\frac{area \;of\; wall}{area \;of\; can}[/tex]
=[tex]\frac{180}{0.4211}[/tex]
= 427.45 cans

The perimeter of an equilateral triangle must be at most 57 feet. Create an inequality to find what the length of the sides should be. Solve the inequality by showing all of your work and explaining each step.
Answers
Answer:
[tex]L[/tex] ≤ [tex]29[/tex]
Step-by-step explanation:
Given
Perimeter = 57 (at most)
Required
Determine the length of each side
The term at most in the values of the perimeter shows that the expression is an inequality and it means that perimeter can't exceed that value;
Let L represents the length of each sides;
Perimeter [tex]=L+L+L[/tex]
So,
[tex]L+L+L[/tex] ≤ [tex]57[/tex]
[tex]3L[/tex] ≤ [tex]57[/tex]
Divide both sides by 3

D. r = 9sec^2 theta
Answers
From the graph and orientation of the parametric equations: A. the graph is a circle with a radius of 4. The orientation is counterclockwise as t increases.
How to find a polar function?In geometry, the relationship between the rectangular coordinates (x, y) and polar coordinates (r, t) is given by these polar functions:
x = rcost and y = rsint.
Where:
t is the angle.r is the radius of a circle.Mathematically, the standard form of the polar equation of a circle is given by;
x² + y² = r²
Given the following data;
x = 16cost ⇒ x² = 16cos²t
y = 16sint ⇒ y² = 16sin²t
Evaluating, we have:
x² + y² = 16
r² = 16
r = √16
Radius, r = 4.
Also, the orientation is counterclockwise as t increases because the angle gets bigger (increases).
How to determine polar form of the parametric equations?x = 3t .....equation 1.
y = t² .....equation 2.
Making t the subject of formula in eqn. 1, we have:
t = x/3 .....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
y = (x/3)²
rsinθ = (rcosθ/3)²
rsinθ = r²cos²θ/9
9rsinθ = r²cos²θ
9sinθ = rcos²θ
r = 9sinθ/cos²θ
r = 9 × (sinθ/cosθ) × 1/cosθ

Dan purchased a set of knitting needles for $11 and 6 identical packs of yarn. The total cost was $89.
How much did each pack of yarn cost?
Answers
Answer:
13$
Step-by-step explanation:
Dan purchased a set of knitting needles for $11 and 6 identical packs of yarn. The total cost was $89.
How muc[tex]rweds[/tex]h did each pack of yarn cost?
The total cost of each pack of yarn is $13.
What is a total cost?The total cost of an item is the sum of the cost of all items that are purchased. Total cost for more items can be found by multiplying the number of items and the cost of the individual item.
For the given situation,
There are two items purchased knitting needles and packs of yarn.
Cost of knitting needle = $11
Number of packs of yarn purchased = 6
Total cost = $89
Let the cost of yarn be x.
The cost of the yarn can be find by using the equation,
Total cost = Cost of knitting needle + (number of yarn purchased × x)
⇒ [tex]89=11+6x[/tex]
⇒ [tex]6x=78[/tex]
⇒ [tex]x=13[/tex]
Hence we can conclude that the cost of each pack of yarn is $13.

Permutation helps us to know the number of ways an object can be arranged in a particular manner. The number of ways the remaining player can be arranged is 1,814,400.
What is Permutation?Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.
[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]
where,
n is the number of choices available,
r is the choices to be made.
Given that the team has 11 players while there are only 9 positions available, therefore, the number of ways the coach can choose 9 people and arrange them is,
[tex]^{11}P_9 = \dfrac{11!}{(11-9)!} = \dfrac{11!}{2!} = 19,958,400[/tex]
Now, since Amy does not want to be a pitcher, therefore, the number of ways the remaining people can be arranged in the place of the pitcher is 10. Also, the position remaining in the team is 8, while the number of people remaining is 10. Thus, the number of ways the remaining people can be arranged are,
[tex]\text{Number of ways}= ^{10}P_8 =\dfrac{10!}{(10-8)!} = 1,814,400[/tex]

Answer:
sinA = 0.79 tanA = 1.3
Step-by-step explanation:
Step1:
Find the length of the line going through the middle from A to C by using pythagorean theorem.
a = 13
b = 12
c= ?
c = sqrt(a^2 + b^2)
c = sqrt(13^2 +12^2)
c = 17.69
Step 2:
Use pythagorean theorem again to find the length of the line going from A to D.
a = ?
b = 14
c = 17.69
c^2 = a^2 + b^2
Now solve for a.
a^2 = c^2 - b^2
a = sqrt(c^2 - b^2)
a = sqrt(17.69^2 - 14^2)
a = 10.81
Step 3:
Use trignometry to find the values of sinA and tanA
sinA = opposite/hypotenuse = 14/17.69 = 0.79
tanA = opposite/adjacent = 14/10.81 =1.3

Answers
Answer:
The expression represent the total amount of price money is 3x-150.
The expressions let X be the amount of money for first place. This means X-50 would be the amount of second place because each subsequent place after 1st wins $50 less than the previous place. Thirds, would be X-50-50 or X-100.
That is X = first place and each place after that is 50 less so 2nd place would be x - 50 and third place would be x - 100.
Thus the total amount of money would be all of the values combined which is
x + (x - 50) + (x - 100)
Combinimg the like terms
What is the combinimg the like terms?
To combine like terms, we have to add the coefficients and keep the variables the same. We add like terms to make one term.
x+x-50+x-100
3x-150
3x - 150
Therefore the option b is correct.
So the expression represent the total amount of price money is 3x-150.
