Answer:

The area of the sector should be 9.42[tex]cm^2[/tex] .

Step-by-step explanation:

-The formula for finding the area of a sector:

[tex]A = \frac{Arc}{360} \pi r^2[/tex]

-Next use the arc measure and the radius in order to solve and get the answer:

[tex]A = \frac{120\textdegree}{360\textdegree}\pi 3^2[/tex]

-Solve:

[tex]A = \frac{120\textdegree}{360\textdegree}\pi 3^2[/tex]

[tex]A = \frac{120\textdegree}{360\textdegree}\pi \times3^2[/tex]

[tex]A = \frac{1}{3} \pi \times 3^2[/tex]

[tex]A = \frac{1}{3} \pi \times 9[/tex]

[tex]A = 3\pi \approx 9.424[/tex]

-Round to the nearest hundredth:

[tex]A \approx 9.42[/tex]

A, B, D

Step-by-step explanation:

Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.

33x-33= 33x + 25

33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.

33x+33=33x+25

33x+8= 33x nope no solution

33x+25=33x+25

33x = 33x both sides identical so there is a solution

33x-25 = 33x +25

33x= 33x+50

1/9 = 0.111111111..., No

7/9 = 0.777777...8, No

9/10 = 0.9, Yes

Dividing by a non-factor of 9 by 9 will always result in an infinite decimal, similar to dividing a non-factor of 3 by 3 or a non-factor of 7 by 7.

However, dividing a number by 10 will simply move the decimal one value to the right, so 9.0 divided by 10 is 0.90.

Answer: (pi) (6 squared)

Step-by-step explanation:

Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:

Area of a circle: (pi) radius^2

The diameter (d) of a circle is equal to: 2 radius

So:

D = 2r

Replacing with the value given:

12 =2r

12/2=r

radius= 6 inches

Back with the Area formula:

A = (pi) 6^2

B is correct

Answer:

V≈3.09×108

Step-by-step explanation:

Shape: Cylinder

Solved for volume

Radius: 333

Height: 888

Formula: Radius, Height

Exact answer: V≈3.09×108

Hope this helps.

The volume of the cylinder is = 98,469,432π

The radius of the cylinder = 333

The height of the cylinder = 888

Therefore the volume is = ?

The formula for the volume of cylinder = πr²h

V = π× 333² × 888

V = π × 110,889× 888

V = 98,469,432π

Therefore, the volume of the cylinder is = 98,469,432π

Answer:

number five: 37.065 number six 241

Step-by-step explanation:

FOR NUMBER FIVE:

so for the rectangles, the formula is L * W.   L for length W for width

so 5×3 = 15. and there are 2 rectangles with the same measurment so its

15 + 15 which is 30 (for both rectangles)

and for the circle formula its pi r^2 where pi is 3.14 and r is radius

so 3.14 × 3^2 = 28.26. but since its a quarter of a circle, divide it by four which is 7.065.

so 30 + 7.065 = 37.065

FOR NUMBER SIX:

the area of a triangle formula is b * h ÷ 2 where b is base and h is height

so its 22 * 8 / 2 = 88

and for the trapezoid the formula is [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is height

so its[tex]\frac{12+22}{2} *9[/tex] = 153

88+153= 241

Answer: 1/9

Step-by-step explanation:

You have 3 possible options. The probablility of the spinner landing on 3 is 1/3. The probability of it landing on 2 is also 1/3. For them to happen together, you multiply them. 1/3 * 1/3 = 1/9.

The probability of landing on a 3 and then landing on a 2 is,

⇒ 1/9

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Given that;

You spin the spinner twice.

Now, The probability of the spinner landing on 3 is,

⇒ 1/3.

And, The probability of it landing on 2 is,

⇒ 1/3.

Hence, The probability of landing on a 3 and then landing on a 2 is,

⇒ 1/3 × 1/3

⇒ 1/9.

Step-by-step explanation:

How much money she makes from each bracelet:

9-4.35=$4.65

How much money she makes from the 15 bracelets:

4.65 x 15= $69.75

Answer:

Part 1: 4.65

Part 2: 69.75

Step-by-step explanation:

The first question is "How much money does she make from each bracelet after she pays herself back for the materials?"

To answer that, we must find how much she is selling them for ($9) and subtract the cost of the materials from it ($4.35), which equals 4.65

The second question is How much money does becca make from the sale of 15 bracelets?

In other words, they are only asking for the profit made which means they don't want the materials used cost included. So we can use the answer from before and multiply by 15, so 4.65*15=69.75.

Hope that makes it clear, and good luck with studies :)
