The measure of arc ECF in circle G is 98°. The correct option is the second option 98°

From the question, we are to determine the measure of arc ECF

By using the one of the circle theorems

The angle subtended by an arc of a circle is twice the angle it subtends anywhere on the circle's circumference

In the given diagram,

∠F = 1/2 ×104°

∠F = 52°

∠D + ∠E + ∠F = 180° (Sum of angles in a triangle)

∠D + 79° + 52° = 180°

∠D = 180° - 79° - 52°

∠D = 49°

m arc ECF = 2 × m ∠D

m arc ECF = 2 × 49°

m arc ECF = 98°

Hence, the measure of arc ECF in circle G is 98°. The correct option is the second option 98°

EOQ=√148,400

EOQ=385

b. Reorder point

Reorder point=5300/250×12 days

Reorder point=254

c. Reorder point

Reorder point=5300/250×35 days

Answer:

41.83 inches

Step-by-Step Explanation:

You have to trust me. I helped my brother with this.

The length of the shortest side of the hexagon is approximately 41.83 inches

Let's denote the length of the shortest side of the hexagon as "x" inches. According to the given information, each side of the hexagon is 10 inches longer than the previous side.

So, the lengths of the sides of the hexagon can be expressed as follows:

First side: x inches

Second side: (x + 10) inches

Third side: (x + 20) inches

Fourth side: (x + 30) inches

Fifth side: (x + 40) inches

Sixth side: (x + 50) inches

To find the perimeter of the hexagon, we sum up the lengths of all the sides:

Perimeter = x + (x + 10) + (x + 20) + (x + 30) + (x + 40) + (x + 50)

We know that the perimeter is given as 401 inches, so we can set up the equation:

401 = x + (x + 10) + (x + 20) + (x + 30) + (x + 40) + (x + 50)

Simplifying the equation:

401 = 6x + 150

Subtracting 150 from both sides:

251 = 6x

Dividing both sides by 6:

x = 251/6

Therefore, the length of the shortest side of the hexagon is approximately 41.83 inches (rounded to two decimal places).

first lets find the volume of the cylinder the formula for the volume of a cylinder is pi times radius squared times height. so after plugging in the height and radius you get 689.64242

cone:

radius=5.6 height=6.8

now the volume of the cone, the formula for the volume of a cone is pi times radius squared times height/3. so after plugging in the height and radius of the cone you get 223.31278

Answer:

a. 17

b. 30

c. 5

Step-by-step explanation:

English (E) = 28 - 15 (10+8-3) = 13

Amharic (A) = 30 - 10 (8+5-3) = 20

Afan Oromo (AO) = 42 - 12(10+5-3) = 30

E+AO = 10

E + A = 8

A + AO = 5

A + AO + E = 3

a. 13 people spoke just English+ 20 people who just spoke Amharic + 30 people who just spoke Afan Oromo+ The multilingual people (10+8+5-3=20) which is 83, so that means that 17 learned no language.

b. 42 People learned Afan Oromo, but only 30 of them learned that language separately. 10 People learned it along with English, and 5 learned it with Amharic. However, 3 of those people were the same, so 12 people of those 42 spoke multiple languages. Therefore, only 30 people spoke just Afan Oromo.

c. This one is kinda just a trick question, they want you to overthink it because of the 3 who learned all, but it's just 5 like it says in the question.

The future value is $10,354.72.

The total interest earned is $754.72.

When an amount is compounded quarterly, it means that both the amount deposited and interest already earned increases in value every quarter.

The future value = quarterly deposit x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

Annuity factor = [1.01^16) - 1 ] / 0.01 = 17.26

17.26 x 600 = $10,354.72
