Answer:
Height, h = 9 m
Step-by-step explanation:
Given that,
The volume of a water tank, V = 254.34 m³
The diameter of the tank, d = 6 m
We need to find the height of the clinder. The volume of a cylinder is given by :
[tex]V=\pi r^2h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{254.34}{3.14\times (3)^2}\\\\h=9\ m[/tex]
So, the height of the cylinder is 9 m.
Find the product.
(x-3)(x+5)
Answer:
x2+5x-3x-15=x2+2x-15
Step-by-step explanation:
(x)(x)=x2,(x)(5)=5x
(-3)(x)=-3x,(-3)(5)=-15
Answer: X^2 + 8x -15
Step-by-step explanation:
Use the foil method.
First, outer, inner, last
Multiply the first numbers inside each parenthesis. X*X = x^2
Next multiply the outer number in each parenthesis. X*5 = 5x
Then multiply the inner numbers of the parenthesis. -3*x= 3x
Finally multiply the last numbers in the parenthesis. -3*5 = -15
Now add all of these together
X^2 + 5x + 3x + -15
Combine like terms
X^2 + 8x -15
X can be solved from here, however it does not seem that you are asked to solve for x
this will help me a lot if you anwser this

How is the quotient 5 to the 8th power expressed as a power of 5
Answer:
5^4
Step-by-step explanation:
When dividing exponents with the same base, you subtract their exponents.
8-4=4
This means that 5^8 / 5^4 is equal to:
5^4
Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
Answer:
4[tex]x^{2}[/tex]-16x+8
Step-by-step explanation:
4(x - 2)(x - 2) - 8 = 4([tex]x^{2}[/tex] - 4x + 4) - 8 = 4[tex]x^{2}[/tex] - 16x + 16 - 8 = 4[tex]x^{2}[/tex] - 16x + 8.
Answer:
[tex]f(x) = 4x^2 -16x + 16[/tex]
Step-by-step explanation:
f(x)=4(x-2)² Simplify.
f(x) = 4x^2 - 16x + 16
Form f(x)=ax²+bx+c.
f(x) = 4x^2 - 16x + 16

Step-by-step explanation:
A number m is no less than –1 or less than or equal to −5.
Answer:
-1 < m ≤ - 5
Step-by-step explanation:
Your expression includes: m, -1, -5, >, ≤
m is the value being compared so it will be in the middle.
# sign m sign #
m is no less than -1: no less than means it is greater than -1, but does not include -1. Therefore, our sign is >
m > -1
m is less than or equal to -5. This means we use ≤ because it can equal -5.
m ≤ -5
Now combine the two expressions
m > -1 – This can also be written as -1 < m.
m ≤ -5
-1 < m ≤ - 5

The six sides of a number cube are labled 1,2,3,4,5,6, . You flip a coin and roll the number cube what is the probability that you land on tails and get a number less than 3.
Answer:
1/6 or 16.67%
Step-by-step explanation:
The probablility for the coin is 50% and the probablility for the cube is 2/6 or 1/3 aka 33.3%. You need to multiply these together to figure out the percentage so 1/2 time 1/3 is 1/6.
yeah, i need help solving this and i need help quick please.
In band, there are 3 woodwinds for every 1 percussion
player. What is the ratio of woodwinds to percussion players?
Answer:
3:1
Step-by-step explanation:
For every 3 woodwinds, there is 1 percussion.
Note:
6:2, 9:3, 12:4 are equivalent to 3:1.
Every time you add 3 to the first value, and 1 to the second value.
Answer:
3:1
Step-by-step explanation:
it is pretty self-explanatory. For every x amount of percussionists there are y amount of woodwinds.
y:x
y=3
x=1

What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6?
Answer:
The coordinates of the point P in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:
(x, y) = (-1, -7)Step-by-step explanation:
Let P be the point.
As the point P is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6
i.e.
(x₁, y₁) = (-2,-8)
(x₂, y₂) = (5,-1)
Rise = y₂ - y₁ = -1 - (-8) = -1 + 8 = 7
Run = x₂ - x₁ = 5 - (-2) = 5 + 2 = 7
1 : 6 ratio means the point P lies at
[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]
Thus,
rise for P = 7 × 14% = 1
run for P = 7 × 14% = 1
Thus, coordinates of P will be:
x = -2 + 1 = -1
y = -8 + 1 = -7
Thus,
The coordinates of the point P in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:
(x, y) = (-1, -7)work out the value of 7^2+4^3x2^5

4. Your job as a carpenter pays $20/hour and you worked 40 hours last week. The taxes
withheld from your wages were $83 federal tax and $19 state tax. Your total check is
a. $698
b. $720
c. $810
d. $912
Answer:
698.00 (A)
Step-by-step explanation:
20.00x40=800.00
83.00+19.00=102.00
800.00-102.00=698.00
The total amount of the check will be $698. Then the correct option is A.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Your job as a carpenter pays $20/hour and you worked 40 hours last week.
Then the amount that you earn in 40 hours will be
⇒ $20 x 40
⇒ $800
The taxes withheld from your wages were $83 federal tax and $19 state tax. Then the total amount of the check will be
⇒ $800 - $83 - $19
⇒ $800 - $102
⇒ $698
The total amount of the check will be $698. Then the correct option is A.

Step-by-step explanation:
Answer:
b=21
Step-by-step explanation:
For this problem we need to use Pythagorean theorem (a^2+b^2=c^2):
20^2+b^2=29^2
Simplify the squares:
400+b^2=841
Subtract 400 from both sides:
b^2=441
Take the square root of both sides:
b=21
