A circle has an area of 20cm. What is its diameter?
Answer:
should be 5.05
Step-by-step explanation:
rounded to nearest hundredth
Answer:
5.02
Step-by-step explanation:
Formula for area= π x r^2
(π is 3.14)
Formula for diameter= 2 x r
So all you basically have to do is go backwords with the first equation
20/π=6.36
Now you have 6.36, though you need to go even further back because of the ^2
√6.36=2.51
Now we have the radius, so stick that into the diameter formula
2 x 2.51
5.02 is the diameter :)

If a1= 3 and an= 2an-1 then find the value of 06.
Answer:
a₆ = 96
Step-by-step explanation:
assuming you mean find a₆
using the recursive rule and a₁ = 3 , then
a₂ 2a₁ = 2 × 3 = 6
a₃ = 2a₂ = 2 × 6 = 12
a₄ = 2a₃ = 2 × 12 = 24
a₅ = 2a₄ = 2 × 24 = 48
a₆ = 2a₅ = 2 × 48 = 96

Given C is the midpoint of line AB, D is the midpoint of line AC, and E is the midpoint of line DC. If AE=16, what is DB?
Answer:
DB = 32
Step-by-step explanation:
Given :
⇒ C is the midpoint of the line AB
⇒ E is the midpoint of the line DC
⇒ AE = 16
=============================================================
Understanding :
⇒ AC = BC = 1/2AB
⇒ AD = DC = 1/2AC = 1/4AB
⇒ DE = 1/2AD = 1/4AC = 1/8AB
=============================================================
Finding AB :
⇒ AE = AD + DE
⇒ 16 = 1/4AB + 1/8AB
⇒ 3/8AB = 16
⇒ AB = 16 x 8 / 3
⇒ AB = 128/3
=============================================================
Finding DB :
⇒ DB = DC + CB
⇒ DB = 1/4AB + 1/2AB
⇒ DB = 3/4AB
⇒ DB = 3/4 × 128/3
⇒ DB = 128/4
⇒ DB = 32

Complete the ratio table to convert the units of time from hours to weeks or weeks to hours.
Hours
Weeks
168

1,008

The correct answers are 1008 hours are 6 weeks and 5 weeks are 840 hours.
What is the ratio?The ratio indicates how many times one number is to the other number.For example, if you have 4 chocolates and 2 cakes the ratio of the chocolates and the cake will be 2:1 which means that chocolate is 2 times then the cake.
It is given that 168 hours is equal to 1 week. we need to find 1008 hours has how many weeks and 5 weeks has how many hours.
1.) 1008 hours has how many weeks
168 hours = 1 week
1 hour = 1 / 168 weeks
1008 hours = 1008 / 168 = 6 weeks
So 1008 hours has 6 weeks
2.) 5 weeks has how many hours.
1 week = 168 hours
5 weeks = 5 x 168 hours
5 weeks = 840 hours
So 5 weeks will have 840 hours.
Therefore correct answers are 1008 hours are 6 weeks and 5 weeks are 840 hours.

Let O be an angle in quadrant III such that cos 0 = -2/5 Find the exact values of csco and tan 0.
well, we know that θ is in the III Quadrant, where the sine is negative and the cosine is negative as well, or if you wish, where "x" as well as "y" are both negative, now, the hypotenuse or radius of the circle is just a distance amount, so is never negative, so in the equation of cos(θ) = - (2/5), the negative must be the adjacent side, thus
[tex]cos(\theta)=\cfrac{\stackrel{adjacent}{-2}}{\underset{hypotenuse}{5}}\qquad \textit{let's find the \underline{opposite side}} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ \pm\sqrt{5^2 - (-2)^2}=b\implies \pm\sqrt{25-4}\implies \pm\sqrt{21}=b\implies \stackrel{III~Quadrant}{-\sqrt{21}=b}[/tex]

Determine the equation of the elastic curve for the beam using the x1 coordinate for 0 ≤ x1 ≤ l/2
The elastic curve between 0 to L/2 is a cubic curve. And the elastic curve is shown in the given diagram.
What is an elastic curve?The flexible curve of a beam is the curve generated by the crossover of the horizontal member with the beam's side, with continuous stresses on the fibers considered to be within the elastic limit.
The slope at L/2 will be
[tex]\rm \theta _{L/2} = \dfrac{PL^2}{8EI}[/tex]
The deflection of the beam at L/2 will be
[tex]\rm y_{L/2} = \dfrac{P(L/2)^3}{3EI}\\\\\rm y_{L/2} = \dfrac{PL^3}{24EI}[/tex]
And the deflection of the beam at L will be

Find the value of x. (‼️‼️‼️‼️
Answer: 5
Step-by-step explanation:
What does x equal with this equation
x/6-33= -27
Answer:
The first thing that we have to do is add 33 to both sides to try to reduce the amount of variables on the left hand side.
[tex]\frac{x}{6} - 33 = -27[/tex]
[tex]\frac{x}{6} - 33 + 33 = -27 + 33[/tex]
[tex]\frac{x}{6} = 6[/tex]
Now that we have simplified the left hand side even more we only have one part left to get x by itself which is to multiply both sides by 6.
[tex]\frac{x}{6} = 6[/tex]
[tex]\frac{x}{6} * 6 = 6 * 6[/tex]
[tex]x = 36[/tex]
Therefore, our final answer for what the value of x equals is 36.

Completely factor the given polynomial: 2x^2 - 8x - 10
Answer:
2(x - 5)(x + 1)
Step-by-step explanation:
2x² - 8x - 10 ← factor out 2 from each term
= 2(x² - 4x - 5) ← factor the quadratic
consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)
the factors are - 5 and + 1 , since
- 5 × 1 = - 5 and - 5 + 1 = - 4 , then
x² - 4x - 5 = (x - 5)(x + 1)
then
2x² - 8x - 10 = 2(x - 5)(x + 1) ← in factored form

Step-by-step explanation:
Given M is the midpoint
We know that midpoint of a line divides the line into two equal parts
Therefore on equating we get
[tex]4x + 1 = 8x - 15[/tex]
[tex]1 + 15 = 8x - 4x[/tex]
[tex]16 = 4x[/tex]
[tex]x = 4[/tex]
Steps:
[tex]4x+1= 8x-15[/tex]
=>subtract 4 on both sides with 8x
[tex]1=4x-15[/tex]
=>now do add 15 both sides
[tex]16=4x[/tex]
=>Now divide 4x both sides
[tex]\frac{16}{4} =\frac{4x}{4}[/tex]

Let's solve this problem step-by-step:

x: it is the delta in the equation given in your pictureWe know (7*10) - (7*x) is equivalent to the 7*(10-x)
⇒ based on the Distributive Properties
[tex]a*(b+c) = ab + ac[/tex]
[tex]7*(10+(-x))=(7*10)+(7*(-x)=(7*10)-(7*x)[/tex]
So:
[tex]7*9=7(10-x)\\9=10-x\\x=10-9\\x= 1[/tex]
Thus delta (the little triangle in this problem) in this case is 1

What is the expression that we have to simplify?It is given by:
[tex]\frac{3 + 5\sqrt{x^2}}{4\sqrt{6x^2} - \sqrt{x}}[/tex]
We rationalize the denominator, using the subtraction of perfect squares, hence:

Then, solving the expression:
[tex]\frac{(3 + 5\sqrt{x^2})(4\sqrt{6x^2} + \sqrt{x})}{16(6x^2) - x}[/tex]
[tex]\frac{12\sqrt{6x^2} + 3\sqrt{x} + 20x^2\sqrt{6} + 5\sqrt{x^3}}{96x^2 - x}[/tex]
