Answer:

Step-by-step explanation:

When we add the area of semicircle I and III  of same radius, we get a cirlce.

diameter = 48 cm

r = 48/2 = 24 cm

Area of I and III = area of circle

                         = πr²

                         = 3.14 * 24 *24

                         = 1808.6 cm²

Figure II:

length =  diameter of the bigger semicircle = 48 cm

width = diameter of the smaller circle = 14 cm

Area of rectangle (figure II) = length *width

                                            = 48 * 14

                                            = 672 cm²

Smaller semicircle A & B

diameter = 14 cm

r = 14/2 = 7 cm

Area of Semicircle A & B = Area of a circle

                                         [tex]\sf = \dfrac{22}{7}*7*7\\\\ = 22*7\\\\= 154 \ cm^{2}[/tex]

Area of shaded region =  area of rectangle II + area of figure I & III - area of A &B

            = 672 + 1808.6   - 154

           =  2326.6cm²

Answer:

Step-by-step explanation:

The only way I can solve this is by assuming the letter on the far left is a B. If that is the case, <BAC and <EAC are supplementary.

Ignore the line going from C to D and look at the angle that is left. <EAC is out in the open. What happens is that <EAC and <BAC share the same starting poing which is A.

Each of the angles divide the diameter in two. The construction makes a total angle of 180 degrees which makes them supplementray.

<BAC + <EAC = 180o

<EAC = 31 degrees         Given. Substitute that value into the equation above.

<BAC + 31 = 180              Subtract 31 from both sides.

<BAC +31-31 = 180 - 31    Combine

<BAC = 149

Answer:

C

Step-by-step explanation:

given the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{LM}{PR}[/tex] = [tex]\frac{LN}{PQ}[/tex] ( substitute values )

[tex]\frac{n}{1.8}[/tex] = [tex]\frac{4.35}{3}[/tex] ( cross- m ultiply )

3n = 7.83 ( divide both sides by 3 )

n = 2.61 cm

Answer:

Below in bold.

Step-by-step explanation:

The hexagon is made up of 6 equilateral triangles.

So the Base = 12 cm.

Height a = 12 cos 30 = 10.392 cm

So area of 1 triangle =  1/2 * 12 * 10.392 cm^2

- and total area =  6 *  1/2 * 12 * 10.392

= 36 * 10.392

= 374.11 cm^2 to the nearest hundredth.

Answer:

960 cm^3

Step-by-step explanation:

The volume of any object is found by multiplying the area of the base times the height. I'll use the triangular sides as the base in this case. The area of the triangle is (bh)/2, so this calculation is:

(16x12)/2 = 96

The height is 10, so Volume is 96 x 10 = 960 cm^3

Answer:

Option A for part (a) and Option B for part (b)

Step-by-step explanation:

Step 1:  Determine the ratios in part a

First Batch --> 8 minutes / 2 customers = 4 minutes per customer

Second Batch --> 18 minutes / 6 customers = 3 minutes per customer

Third Batch --> 21 minutes / 7 customers = 3 minutes per customer

In part (a) we would choose option a which is that it does not always take the same amount of time to serve each customer.

Step 2:  Determine the ratios in part b

First Batch --> 27 points / 3 dollars = 9 points per dollar

Second Batch --> 45 points / 5 dollars = 9 points per dollar

Third Batch --> 63 points / 7 dollars = 9 points per dollar

In part(b) would choose option b which is that each dollar spent appears to earn the same number of points which would give us 8 dollars for 72 points.

Answer: Option A for part (a) and Option B for part (b)

Answer:  The answer is C ≈ 18.85 meters.

Step-by-step explanation: The formula that you need is...

2 × π (pi or approximately 3.14) × r (which is the radius)

In this case, your radius is 3, so you solve by 2 × π (pi or approximately 3.14) × 3 which equals 18.8495559215 but you round to your nearest hundredth which gets you to have 18.85 meters as your answer! I hope this helps!

Answer:

1/27

Step-by-step explanation:

Okay first, calm down. Math is always hard when your stressed.

First step is to elimate b and write the equation in terms of a. So rearrange a-b=3 to b=a-3. Substitue that into the equation. Now you have :

27^1/3(a-3)

---------------

9^1/2(a)

Now rewrite the equation in terms of 3, you do this by realizing that 9 is simply 3^2 and 27 is simply 3^3. This gives you

3^(a-3)

---------

3^a

Now you use the laws of powers, and you get 3^-3, which is essentially 1/27.
