Answer:

  4.2π cm ≈ 13.19 cm

Step-by-step explanation:

The length s of an arc of a circle with radius r and central angle θ (in radians) is ...

  s = rθ

Here, we have ...

  s = (5.6 cm)(3π/4) = 4.2π cm ≈ 13.19 cm

By comparing medians which person went to the movies the most per month
Nimfa-mama [501]

I think they all went to the movies equally per month if you simply compare medians? Since in the second chart, they each have a median of 2 times per month, that makes it equal. If you aren’t sure if this is correct, you have to order how many times each person went to the movies, from least to greatest. For example, John’s would be 1,1,1,2,2,2,2,3,3,3,4,5. Then you would start crossing numbers off from each end. First you would cross off 1, then 5, and then 1, and then 4, and keep going until you reach the number in the very middle, which is 2. Do this with all of the other people, and check if everybody has 2 for a median. I believe they do, however it’s always best to check and be safe. Good luck

Answer:

P=23.9\ inches

Step-by-step explanation:

<u>Formula Evaluation</u>

Formulas are expressions where a sequence of letters, numbers or symbols have a determined meaning in given system.

Formulas are usually expressed as mathematical operations that connect one or more variables.

The perimeter of a triangle is the sum of the lengths of its sides. Being a,b, and c their sides, then the perimeter has the formula

P=a+b+c

We are given the values of

a=13\ inches

b=7.2\ inches

c=3.7\ inches

Thus the perimeter is

P=13\ inches+7.2\ inches+3.7\ inches

\boxed{P=23.9\ inches}

The trapezoid ABCD has angle C=70 degrees and D=50 degrees. Find the size of angle A and angle B
uranmaximum [27]

Angle A = 130° and Angle B = 110°

Solution:

Given ABCD is a trapezoid with ∠C = 70° and ∠D = 50°

If ABCD is a trapezoid, then AB is parallel to CD.

AD is a transversal to AB and CD and

BC is a tranversal to AB ad CD.

Sum of the interior angles on the same side are supplementary.

∠A + ∠D = 180°

⇒ ∠A + 50° = 180°

Subtract 50° on both sides to equal the expression.

⇒ ∠A = 180° – 50°

⇒ ∠A = 130°

Similary, ∠B + ∠C = 180°

⇒ ∠B + 70° = 180°

Subtract 50° on both sides to equal the expression.

⇒ ∠B = 180° – 70°

⇒ ∠B = 110°

Hence, angle A = 130° and angle B = 110°.
