Althea’s family decided to attend the yearly sailing festival in their town. This year the boat races will include both rowing a

nd sailing craft. Althea was excited about watching the racing events, as well as participating in the activities and seeing the informational booths for children.
1. Althea saw different types of sailboats on the water. She noticed that while each sailboat had triangular sails, different types of boats had different sizes and different numbers of sails. Here are two of the sailboats she saw:

Answer:

(a)

Area= 27ft^2 --- the catboat

Area = 25ft --- the sloop

(b)

Cost = \$40.5 -- the catboat

Cost = \$37.5 --- the sloop

Step-by-step explanation:

Incomplete question (See attachment)

For the catboat, we have:

Base = 9ft\\Height = 6ft

For the Sloop, we have:

Base = 7 + 3 = 10ft

Height = 5ft

Solving (a): The area of both sailboats.

Since both are triangular, we use:

Area= 0.5 * Base * Height

For the catboat

Area= 0.5 * 9ft*6ft

Area= 27ft^2

For the sloop

Area = 0.5 * 10ft * 5ft

Area = 25ft

<em>The catboat has the greater sail area because 27 > 25</em>

Solving (b): Cost of sail for each.

We have the unit price to be:

Unit = \$1.50/ft^2

So, the cost is calculated by multiplying the unit price by the total area.

So, we have:

For the catboat;

Cost = 27ft^2 * \$1.50/ft^2

Cost = \$40.5

For the sloop

Cost = 25ft^2 * \$1.50/ft^2

Cost = \$37.5

Step-by-step explanation:

Given

p = 4 -- independent variables

n = 47 ---- observations

Required

The numerator and denominator degrees of freedom

The denominator degrees of freedom is:

df =n - p - 1

df =47 - 4 - 1

df =42

For the numerator, we have:

df = p

df = 4

In ΔRST, m &lt; R = 104°, r = 20, and t = 10. Find the m &lt; S, to nearest degree.
Mrrafil [7]

9514 1404 393

Answer:

  47°

Step-by-step explanation:

The law of sines helps you find angle T. From there, you can find angle S.

  sin(T)/t = sin(R)/r

  sin(T) = (t/r)sin(R) = (10/20)sin(104°)

  T = arcsin(sin(104°)/2) ≈ 29°

Then angle S is ...

  S = 180° -R -T = 180° -104° -29°

  ∠S = 47°
