Answer:

When using the given information, the diameter of the circle is going to be 28 mL.

Step-by-step explanation:

First, we need to know the formula for finding the area of a circle.

[tex]Area=r^2\pi[/tex]

Now, we need to rearrange the formula so we can find the radius.

[tex]Radius=\sqrt{\frac{A}{\pi} }[/tex]

Next, we plug in the given area into the equation.

[tex]Radius=\sqrt{\frac{615}{\pi}}[/tex]

[tex]Radius=\sqrt{196}[/tex]

[tex]Radius=14[/tex]

Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.

[tex]14 * 2=28[/tex]

So, the diameter of the circle is 28 mL

Answer: 1. [tex]3.72\times10^5[/tex]

2. [tex]6.9\times10^{-1}[/tex]

3. [tex]5.30196\times10^{3}[/tex]

Step-by-step explanation:

We use Standard form to expresss a very large or very small numberc in the product of a decimal form of number [generally between 1 and 10] and powers of ten.

For example : Thirty seven thousand four hundred thirty can be written as 37,430 or it can be written as [tex]3.743\times10^4[/tex].

Let's write the given numbers as

1. Three hundred seventy-two thousands

= 372,000

[tex]=3.72\times10^5[/tex]

2. six nine hundredths

[tex]0.69=\dfrac{69}{100}=6.9\times10^{-1}[/tex]

3. Five thousand, three hundred one and ninety six thousandths

= 5,301. 96

[tex]= 5.30196\times10^{3}[/tex]

Answer:

B, C and F

Step-by-step explanation:

Given

f(x) = [tex]\frac{7}{2x(x+3)(x-9)}[/tex]

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.

solve

2x(x + 3)(x - 9) = 0

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0 → C

x + 3 = 0 ⇒ x = - 3 → B

x - 9 = 0 ⇒ x = 9 → F

Answer: 9, 0, -3

Answer:

Step-by-step explanation:

Carter got twice number of candies in comparison to Sullivan or Sullivan got half number of candies compare to Carter.

" Amount is defined as the representation of total quantity of given object."

According to the question,

Number of candies Sullivan got = s

Number of candies Carter got = 2s

 Compare the given amount of data we get,

Number of candies Carter got = 2(Number of candies Sullivan got )

This shows Carter got twice number of candies comparison to Sullivan.

or

Number of candies Sullivan got = [tex]\frac{1}{2}[/tex] (Number of candies Carter got)

Sullivan got half number of candies compare to Carter.

Hence, we conclude Carter got twice number of candies in comparison to Sullivan or Sullivan got half number of candies compare to Carter.

Answer:

The measure of angle b is 15 degrees,

Step-by-step explanation:

Both triangles are isosceles. The inside one is also a right triangle. Since the big triangle is isosceles and the two angles add up to 120 degrees, they also have to be equal, meaning ∠P≅∠R=60 degrees. The inside triangle is also isosceles, meaning that m∠a=60°-b, which 60°-b representing the measure of the last angle in the smaller triangle. Since ∠a and the third angle are congruent, they each have to equal 45°. 60°-45°=15°. The measure of ∠b=15°.

Answer:

1) B

2) A

Step-by-step explanation:

1) When a triangle is similar it means that all the angle measures are the same.

So for triangle UVT the angle measures are:

U=29.95, V=56.25, T=93.82

For triangle RSQ the angle measures are:

R=29.95, S=56.25, Q=93.82

So the answer is that they are similar (triangle UTV ~triangle RQS)

2) For this problem each sided is proportional because of the parallel lines. (It's been a while since I've done this kind of math but I'll give it a go)

30/25=x/35

25x=30(35)

25x=1050

x=42

Answer:

[tex]y - 308x = 0 \\ y - 122x = 2338 \\ y - 308x = 0ndy - 122x = 2338 \\ y - y - 308x + 122x = - 2338 \\ - 308x + 122x = - 2338 \\ - 186x = - 2338 \\ x = \frac{1169}{93} \\ y = 122 \times ( \frac{1169}{93} ) = 2338 \\ y - ( \frac{360052}{93} ) \\ [/tex]

Answer:

D

Step-by-step explanation:

[tex]KQ = PN[/tex]

We can't state that because we don't know if ∠NPK is 90º

Triangle KPN is similar to triangle KQN

It is the same case as the alternative a, we can't say the triangles are similar because we don't the angles for KPN. We know that LN is perpendicular to NP, but we don't if NP is perpendicular to PK, ∠NPK might be 89,9º, that is almost 90º.

KP = 0.5 LN

Once the four sides of the square are equal, LQ = QN. But from the picture we can only state that KP length is approximately the length of NQ (or 0.5 LN)

PN || KM

That's the correct answer! Once ∠QNP is 90º, PN is perpendicular to KM.

Im pretty sure its 2 but not exactly

Answer:

Step-by-step explanation:

-x - 5y = -29 + 4y - y + 5

Add x to both sides

-x - 5y + x = -29 + 4y - y + 5 + x

-5y = 4y - y  -29 +5 + x  {Add the like terms}

-5y = 3y - 24 + x  {subtract 3y form both sides}

-5y - 8y = 3y - 24 + x - 3y

-13y = x - 24

Divide both sides by (-13)

y = (x-24)/-13

y = -(x-24)/13

Answer:

180-60 = 120 if triangle is not equilateral it cannot be isosceles then depending where the angles are they will show  60,60,60 if equilateral

For isosceles it would need to be 58 61 61 as 60, 60,60 cannot be isosceles.

Vectors 60 if right angled triangle = 90-60 = 30

So angles = 30 and 90 degree or just 120 if angle theta is a vector as explained below.
