Answers

The distribution of the balls is an illustration of proportions, and 4 of the golf balls are yellow

How to determine the number of yellow golf balls?

The distribution of the balls are given as:

Total = 28

Yellow = 1/7

The number of yellow balls is given as:

Yellow = 1/7 * Total

This gives

Yellow = 1/7 * 28

Evaluate the product

Yellow = 4

Hence, 4 of the golf balls are yellow

Answers

Answer:

A. (3 x 5) + (3 x 8)

Step-by-step explanation:

The Distributive property distributes the common factor that the numbers in the parenthesis are multiplied with.

Ex. A(B + C) will equal (A x B) + (A x C).

3 x (5 + 8) will equal (3 x 5) + (3 x 8).

Use trigonometry!

since we know the adjacent and hypotenuse sides, use cos.

Answers

The hypotenuse of the right triangle is 29 units.

The ratios are as follows:

sin x = 20 / 29

cos y = 20 / 29

What is a right angle triangle?

Right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios. The sides can also be solved using Pythagoras theorem.

The hypotenuse side is the longest side of a right angle triangle.

Therefore,

c² = a² + b²

c = √20² + 21²

c = √400 + 441

c = √841

c = 29

hypotenuse = 29 units

sin x = opposite / hypotenuse = 20 / 29

cos y = adjacent/ hypotenuse = 20 / 29
