Answer:

44°

Step-by-step explanation:

First, m ∠ D=112° and  ∠ABC are congruent in a parallelogram and congruent angles have same measure so m ∠ ABC=112° as well

Second, ∠ABC and ∠CBE are supplementary angels so they add up to 180° because adjacent angles that form a line are suplementary, therefore, ∠CBE=180-112=68°

Third, ∠CBE≅∠BCE because the ΔCEB is isosceles since is given CE≅BE and base angles of isosceles triangles are congruent.

Congruent ∠s have same measure so m∠BCE =68° as well

Last sum of angles in a Δ is 180° so from  ΔCEB we have

m ∠E = 180-68-68=44°

Answer:

The correct answer is b) 1100 adults and 1400 students.

Step-by-step explanation:

To find this, set up a system of equations in which x is the number of students who attend and y is the number of adults who attend.

First start by creating an equation for money made.

5x + 10y = 18,000

Now write an equation for the amount that attend.

x + y = 2,500

Now multiply the bottom equation by -5 and add the equations together.

-5x - 5y = -12,500

5x + 10y = 18,000

5y = 5,500

y = 1,100

Since this is the number of adults, we can plug into an original equation to find the number of students.

x + y = 2,500

x + 1,100 = 2,500

x = 1,400

A sphere has a diameter of 14.5 inches.
dlinn [17]

Answer:

≈ 660.5 in²

Step-by-step explanation:

The surface area (A) of a sphere is calculated using the formula

A = 4πr² ← r is the radius

Given diameter = 14. 5 then radius = 7.25, thus

A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²
