Answer:

C. 8.66 in

Step-by-step explanation:

Using the formula of circumference of a circle

[tex]2\pi \: r [/tex]

then,

first find r by plagging in the given data.

so, r = 4.33 in

since it's diameter needed, then

r + r = d

4.33 in + 4.33 in = 8.66 in

Answer:

[tex](\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3=\frac{81}{25}[/tex]

Step-by-step explanation:

Given expression is,

[tex](\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3[/tex]

By solving the given expression,

[tex](\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3=(\frac{\frac{1}{3}+\frac{1}{2}}{\frac{1}{5}})^{-1}+3[/tex]

                     [tex]=(\frac{\frac{2+3}{6}}{\frac{1}{5}})^{-1}+3[/tex]

                     [tex]=(\frac{\frac{5}{6}}{\frac{1}{5}})^{-1}+3[/tex]

                     [tex]=(\frac{5}{6}\times \frac{5}{1})^{-1}+3[/tex]

                     [tex]=(\frac{25}{6})^{-1}+3[/tex]

                     [tex]=\frac{6}{25}+3[/tex]

                     [tex]=\frac{6+(25\times 3)}{25}[/tex]

                     [tex]=\frac{81}{25}[/tex]

Answer is 2

If 8x = 16y

on rearranging question,

x/y = 16/8 = 2

Answer:

x = 1°

Step-by-step explanation:

Bisection means splitting the angle in to 2

So that means 4x-1 = 2x+1

4x-1 = 2x +1

4x = 2x + 2

2x = 2

x = 1°

================================================

Explanation:

a || b means the two lines a and b are parallel

If a || b and b || c, then a || c by the transitive property. Think of it like chaining pieces together.

Since a || c, this means the alternate exterior angles |5x+15| and 100 are congruent, or the same measure.

Solve for x

|5x+15| = 100

5x+15 = 100 or 5x+15 = -100

5x = 100-15 or 5x = -100-15

5x = 85 or 5x = -115

x = 85/5 or x = -115/5

x = 17 or x = -23

The value of x is 17.

When a transversal intersects two or more lines, alternate exterior angles are produced. These angles are created on the various transversal sides' outer edges.

Any two parallel lines that cross a transversal produce a few pairs of angles with the transversal. In the area inside the parallel lines, interior angles are generated, whilst alternative external angles are created in the area outside the parallel lines.

Given:

<1 = 5x + 15

<2 = 100

Using alternate exterior angle

5x + 15 = 100

5x = 100- 15

5x = 85

x= 85/5

x= 17

Hence, the value of x is 17.

Step-by-step explanation:

x int: (1/2,0) and y int (0,2)

Using it's concept, it is found that there is a 0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, it is found that there are 30 students with no cell phones, and of those, 18 are in grade 11, hence the probability is given by:

p = 18/30 = 0.6.

0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

Answer:

11

Step-by-step explanation:

this equation can be derived from the question

45 oz - 17.3 oz - 0.83x oz = 18.57 oz

where x = number of muffins made

combine like terms

45 oz - 17.3 oz - 18.57 oz = 0.83x

9.13 = 0.83x

x = 9.13 / 0.83

x = 11

Answer:

79 is the value

Step-by-step explanation:

Answer:

Ok ok, I see. So the answer is -9.

Step-by-step explanation:

We know the expresion is:

-3(-2+5)

We need to distrubute the -3 to what is in the parthese.

When I say distribute, basically you need to multiply the numbers inside the parethese by -3. So we can think of it as:

-3*-2=6

and:

-3*5=-15

Which we can rewrite as:

(6-15)

Subtract 15 from 6 and you get -9:

6-15=-9

Step-by-step explanation:

Answer:

θ = 0° , 60°

Step-by-step explanation:

[tex]\cos^2\theta + \sqrt{3}\sin \theta \cos \theta = 1[/tex]

[tex]=> \cos^2\theta + \sqrt{3}\sin \theta \cos \theta - 1 = 1 - 1[/tex]

[tex]=> \cos^2\theta + \sqrt{3}\sin \theta \cos \theta - 1 = 0[/tex]

[tex]=> (\cos^2 \theta - 1 )+ \sqrt{3} \sin \theta \cos \theta = 0[/tex]

[tex]=> -\sin^2 \theta + \sqrt{3} \sin \theta \cos \theta = 0[/tex]

[tex]=> \sin \theta(- \sin \theta + \sqrt{3}\cos \theta) = 0[/tex]

Now solve each part separately :-

1) [tex]\sin \theta = 0[/tex]

[tex]=> \theta = \sin^{-1}0 = 0[/tex]

2) [tex]-\sin \theta + \sqrt{3} \cos \theta = 0[/tex]

[tex]=> \frac{-\sin \theta + \sqrt{3}\cos \theta }{\cos \theta} = \frac{0}{\cos \theta}[/tex]

[tex]=> \frac{-sin \theta}{\cos \theta} + \frac{\sqrt{3} \cos \theta}{\cos \theta} = 0[/tex]

[tex]=> -\tan \theta + \sqrt{3} = 0[/tex]

[tex]=> -\tan \theta + \sqrt{3} + \tan \theta = 0 + \tan \theta[/tex]

[tex]=> \tan \theta = \sqrt{3}[/tex]

[tex]=> \theta = \tan^{-1}\sqrt{3} = 60[/tex]

∴ θ = 0° , 60°

Answer:

Solution given:

[tex] \large{ {cos}^{2} \theta + \sqrt{3} sin \theta cos \theta = 1}[/tex]

[tex] 1-sin^{2} \theta+\sqrt{3} sin \theta cos \theta = 1[/tex]

[tex] 1-1 +sin^{2}\theta=\sqrt{3} sin \theta cos \theta = 1[/tex]

[tex] Sin\theta(sin\theta -\sqrt{3}cos\theta)[/tex]

Either

[tex] sin\theta=\sqrt{3} cos \theta [/tex]

[tex] \sqrt{sin\theta}{cos \theta}=\sqrt{3} [/tex]

[tex] Tan \theta =\sqrt{3}[/tex]

[tex] Tan \theta =Tan 60,Tan(180+60),Tan (360+60)[/tex]

[tex] \theta =60°,240°,420°[/tex]

in terms of π is

[tex] \theta =⅓π,\frac{4}{3}π,[/tex]

Or

[tex] Sin\theta=1[/tex]

[tex]Sin\theta=Sin0° ,Sin180°[/tex]

In terms of π is

Answer:

The slope is 5/8

Step-by-step explanation:

-5x+8y = 30

Add 5x to each side

8y = 5x+30

Divide by 8

8y/8 = 5/8x+30/8

y = 5/8x + 15/4

This is in slope intercept form y = mx+b where m is the slope and b is the y intercept

The slope is 5/8

Answer: 5/8

Step-by-step explanation:

You would first need to put the equation into standard form. so you add 5x on both sides

Then you divide 8 on both sides

that would give you y=5/8x+3.75

The slope is 5/8

Answer:

Step-by-step explanation:

The inverse proportional formula is

[tex]y=\frac{k}{x}[/tex] where y is the number of cookies sold, and x is the price per cookie. If we fill in the info given, we can find what it is we are being asked.

When x = 4 (the price of each cookie is $4), 50 cookies are sold (y = 50). Filling in to solve for k:

[tex]50=\frac{k}{4}[/tex] so

k = 200. Using that value of k along with a price of 2 (x = 2), we can find the number of cookies sold, y.

[tex]y=\frac{200}{2}[/tex] so

y = 100 cookies sold when the price is $2 per cookie.

The equation can be solved to find the height of the lamppost 'h' is

D. tan52° = h/18

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

From the given information we have a reference angle of 52° opposite to it is the height(h) of the pole and a shadow which is the adjacent side is 18 feet.

We know, tan = opposite/adjacent.

Therefore, tan52° = h.18.
