Answer:

$Area = 112.1 m^2$

Step-by-step Explanation:

Given:

∆WXY

m < X = 130°

WY = x = 31 mm

m < Y = 26°

Required:

Area of ∆WXY

Solution:

Find the length of XY using Law of Sines

$\frac{w}{sin(W)} = \frac{x}{sin(X)}$

X = 130°

x = WY = 31 mm

W = 180 - (130 + 26) = 24°

w = XY = ?

$\frac{w}{sin(24)} = \frac{31}{sin(130)}$

Multiply both sides by sin(24) to solve for x

$\frac{w}{sin(24)}*sin(24) = \frac{31}{sin(130)}*sin(24)$

$w = \frac{31*sin(24)}{sin(130)}$

$w = 16.5 mm$ (approximated)

$XY = w = 16.5 mm$

Find the area of ∆WXY

$area = \frac{1}{2}*w*x*sin(Y)$

$= \frac{1}{2}*16.5*31*sin(26)$

$= \frac{16.5*31*sin(26)}{2}$

$Area = 112.1 m^2$ (to nearest tenth).

10.In Star School, the ratio of students who bring

Rina8888 [55]

Answer:

There are 406 students in the school

Step-by-step explanation:

Let the number of students in the school be x

The total ratio is 11 + 3 = 14

The ratio that buys lunch is represented by 3

So, we have it that;

3/14 * x = 87

3x = (14 * 87)

x = (14 * 87)/3

x = 406

For the dinner special at a restaurant, the customer must choose an appetizer, a salad, an entree, a side dish, and a dessert. H

Ostrovityanka [42]

Answer:

The number of possible dinner specials are 4368.

Step-by-step explanation:

The number of dinner specials = 5

They include appetizer, a salad, an entree, a side dish, and a dessert.

Possible items to choose from = 16.

They are 1. Appetizer Chicken strips, 2. Shrimp cocktail, 3. Buffalo wings, 4. Potato skins, 5. Salad Garden, 6. Caesar Entree T-bone steak, 7. Pot roast, 8. Lamb Side dish Corn, 9. Rice, 10. French fries, 11. Baked potato, 12. Pinto beans, 13. Dessert Chocolate cake, 14. Brownies, 15. Ice cream, 16. Apple pie

This is a combination problem requiring a combination solution with the following formula and steps:

C (n, r) =? C (n, r) = ?

n choose r

n (objects) = 16

r (sample) = 5

C (n, r) =? C (n, r) = ?

C (n, r) =C (14,5) C (n, r) =C (16,5)

=16! (5! (16−5)!) =16! (5! (16−5)!)

= 4368
