a) If volume of a cylinder is 4817 and the radius is 4, find the height.
Answer:
71. 8
Step-by-step explanation:
volume of a cylinder = 4/ 3 π r² h
=> 4817 = 4/ 3 × 22/ 7 × 4² × h
=> h = (4817 × 3 × 7)/ (4 × 22 × 4²)
=> h = 71.8

Answer:
5,1
Step-by-step explanation:
x= tan27⁰ x 10 ≈ 5,1
.....
Answer:
b or c or 5.1
Step-by-step explanation:
The basic trig identity that does not involve the hypotenuse is the Tan(theta).
Tan(theta) = opposite / adjacent. That definition applies only to a right triangle. It has to be modified if the triangle is some other kind.
The opposite side is the one not making up the reference angle (x in this case).
The adjacent side is the one making up the angle that is not the hypotenuse.
opposite side = x
adjacent side = 10
theta = 27 degrees.
Tan(theta) = opposite / adjacent
Tan(27) = x / 10
Tan(27) = 0.5095
0.5095 = x / 10 Multiply by 10
10*0.5095 = x
x = 5.095
It rounds to 5.1
No one except the answer key can know whether to choose b or c.

Please help me show my work for, Larry has a piece of wood that is 2.45 feet long and 2.097 inches wide. Part B: Using the width of the wood in Part A, what is the area, in square feet, of the piece of wood rounded to the nearest hundredth? Plsss hurry and help me
Answer: 0.43ft²
Step-by-step explanation:
You didn't really specify part A but In assuming that the question you posted is part A. Anyways in this case, area will be calculated by multiplying the length by the width.
Since the piece of wood has a length that is 2.45 feet and width that is 2.097 inches, then the area will be:
= 2.45 × 0.17475
= 0.4281375 ft²
= 0.43ft² to nearest hundredths
Note 1 foot = 12 inches
Therefore, 2.097 inches = 2.097/12 = 0.17475 feet
Find the area of the shaded region.
Answer:
Area of shaded region = 134.13 square feet
Step-by-step explanation:
Area of the shaded region = Area of square - Area of circle
[tex]= ( 25 \times 25) - ( \pi 12.5^2)\\= 625 - 490.87\\= 134.13 ft^2[/tex]
P= -4b^2+6b-9
Q= 7b^2-2b-5
P-Q=
Answer:
P - Q = - 11b² + 8b - 4
Step-by-step explanation:
P - Q
= - 4b² + 6b - 9 - (7b² - 2b - 5) ← distribute parenthesis by - 1
= - 4b² + 6b - 9 - 7b² + 2b + 5 ← collect like terms
= - 11b² + 8b - 4
someone PLEASE help me. this is an area of sectors problem and im confused.

The radius of a circle is 6 feet. What is the area of a sector bounded by a 126° arc?
give your exact answer in SIMPLEST FORM
Answer:
12 3/5 pi
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = pi ^^2
A = 36 pi
Then find the fraction of the circle that is shaded
A circle is 360 degrees
126/360 =7/20
Multiply the area by the fraction
7/20 * 36 pi
63/5 pi
12 3/5 pi
Answer:
the area of sector is
[tex] \frac{126}{360} \times \pi \times 6 {}^{2} = \frac{63}{5} \pi[/tex]
Determine the discriminant for the quadratic equation 0=-2x^2+3. Based on the discriminant value, how many real number solutions does this equation have ? Discriminant = b^2-4ac
Answer:
Two real distinct solutions
Step-by-step explanation:
Hi there!
Background of the Discriminant
The discriminant [tex]b^2-4ac[/tex] applies to quadratic equations when they are organised in standard form: [tex]ax^2+bx+c=0[/tex].
All quadratic equations can be solved with the quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex].
When [tex]b^2-4ac[/tex] is positive, it is possible to take its square root and end up with two real, distinct values of x.
When it is zero, we won't be taking the square root at all and we will end up with two real solutions that are equal, or just one solution.
When it is negative, it is impossible to take the square root and we will end up with two non-real solutions.
Solving the Problem
[tex]0=-2x^2+3[/tex]
We are given above equation. Notice how there are values for a and c but none for b, as there is no bx term. This means that the value of b is 0. We can rewrite the equation so it shows this:
[tex]0=-2x^2+0x+3[/tex]
Now that we have the values of a, b and c, we can plug them into the discriminant:
[tex]D=0^2-4(-2)(3)\\D=-4(-2)(3)\\D=-4(-6)\\D=24[/tex]
Because 24 is positive, there are two real, distinct solutions for this equation.
I hope this helps!

2x^2 − 5x − 1 = 0
Answer:
x = 2.69 or x = -0.19
Step-by-step explanation:
Given:
2x² − 5x − 1 = 0
x = {-b ± √b² - 4ac} / 2a
a = 2
b = -5
c = -1
x = {-b ± √b² - 4ac} / 2a
= {-(-5) ± √(-5)² - 4(2)(-1)} / 2 * 2
= {5 ± √25 - (-8)} / 4
= {5 ± √25 + 8} / 4
= 5 ± √33 / 4
= 5 ± 5.75 /4
x = 5/4 + 5.75/4 or x = 5/4 - 5.75/4
x = 10.75/4 or x = -0.75/4
x = 2.69 or x = -0.19

The seating capacity of a basketball stadium is 5,782. The seats are arranged in 24 sections of the same size. Any seats that are leftover from the 24 sections are called priority seats. How many seats are priority seats? I did not understand how to solve this problem.
Divide capacity by sections:
5782 / 24 = 240.9167
The number of seats in each section is needs to be a whole number so there are 240 seats per section:
240 seats per section x 24 sections = 5,760 seats.
Priority seats is capacity - total section seats:
5782 - 5760 = 22
There are 22 priority seats

Calculate the exact value of 0.5/0.5 * 0.3. Show working please
Answer:
0.3 if you typed the calculating correctly.
because then all operations are of the same priority and ranking, and we go simply from left to right :
0.5/0.5 = 1
and then there is 1 × 0.3 = 0.3
but if you missed to write any brackets like for
0.5/(0.5 × 0.3)
then this goes differently, because now 0.3 is in the bottom part of the division/quotient.
we can still shorten the expression, as the 0.5 on top and on the bottom eliminate each other to 1. but it leaves us with
1/0.3
now, what is 0.3 ?
it is actually 3/10.
so, we have 1/(3/10) which is the same as
(1/1) / (3/10)
to solve this, the two inner numbers of the quotient multiply and the two outer numbers multiply giving us
(1×10) / (1×3) = 10 / 3 = 3.33333...
so, please pick the solution that best fits your actual question.
