Answer:

Step-by-step explanation:

The surface area (A) of a sphere is calculated as

A = 4πr² ← r is the radius

The diameter is given as 10, hence r = 5

A = 4π × 5² = 4π × 25 = 100π ≈ 314.16 mi² ( to 2 dec. places )

Answer:

Angle 1=66

Step-by-step explanation:

Step 1, solve for angle 2

<2+123=180 degrees

Angle 2=57 degrees

Step 2, solve for angle 1

Since this is an isosceles triangle, to solve for angle 1, the equation is 2(57)+x=180

Angle 1=66 degrees

timofeeve [1]

Answer:

Step-by-step explanation:

A = 70*M

B = 500 + 50*M

Costing the same means equal, so we have the equation:

70M = 500 + 50M

-50M -50M

20M = 500

20M / 20 = 500 / 20

m- 25 months

5 goodie bags
25 pies
25/2= 12.5
12.5=2.5
The answer varies if you choices are whole numbers or fraction, right now it would be 2 and a half pies but it could change if they are asking for a whole number
