apply the 30-60-90 triangle theorem to find the length of the shorter leg of a triangle if the length of the hypotenuse is 20 cm ​

Answers

The shorter side is of measurement of 10 cm.

Given that:

The length of the hypotenuse = 20 cm.

The triangle has its angle as 30, 60 and 90 degrees.

Since the given triangle is a right angle, thus we can use trigonometric ratios.

Taking the 60 degree angle we will have:

Similarly,

Thus, the shorter side is base with the measurement of 10 cm.

The instructions on a bottle of laundry detergent tell you to add two capfuls of detergent to each gallon of water. One capful of detergent is equal to about one tablespoon. if your washing machine holds 11 gallons of water, how many tablespoons of detergent will you need to add? How many fluid ounces of detergent?

Answers

Answer:

A.You will need to add 22 tablespoons of detergent to a washing machine that holds 11 gallons of water

B. You will need to add 11 fluid ounces of detergent to a washing machine that holds 11 gallons of water

Step-by-step explanation:

1. Let's review all the information provided to answer the question:

2 capfuls of detergent to 1 gallon of water

1 capful of detergent = 1 tablespoon

2. If your washing machine holds 11 gallons of water, how many tablespoons of detergent will you need to add? How many fluid ounces of detergent?

For finding the amount of capfuls for 11 gallons of water, we multiply this way:

11 * 2 = 22 capfuls of detergent

Now, we can calculate the number of tablespoons, this way:

22 capfuls = 22 tablespoons

You will need to add 22 tablespoons of detergent to a washing machine that holds 11 gallons of water

Fiinally, let's calculate the amount of fluid ounces of detergent, this way:

1 tablespoon = 0.5 fluid ounces

22 tablespoons * 0.5 = 11 fluid ounces

You will need to add 11 fluid ounces of detergent to a washing machine that holds 11 gallons of water

Find the area of a trapezoid if the altitude is 6 inches and the median is 8 inches. (Hint: Recall that the median of a trapezoid is equal to half the sum of the bases.)
24 sq units
48 sq. units
96 sq. units

Answers

Answer:

48 sq. units

Step-by-step explanation:

The area of a trapezoid is given by half sum of the bases multiplied by the height

where a and b are the two parallel sides of the trapezoid and h is the height or amplitude of the trapezoid

But you are aware that, the median of a trapezoid is equal to half the sum of the bases, thus the first part of the formulae  is covered by the median

Hence area, A, of a trapezoid is simplified to product of median and amplitude

Answer:

=48 sq. units.

Step-by-step explanation:

Area of a trapezoid =h× (a+b)/2

(a+b)/2 is the median ( half of the sum of the two parallel sides also called the bases.

Median=8 inches

Altitude is the distance between the two parallel sides= 6 inches

A=6 inches×8 inches

=48 sq. units.
