The answer is True.

A compound event is one in which there is more than one possible outcome. It is also defined as a probabilistic event with two or more favorable outcomes. For example, when you throw a die (singular for dice), it is called a simple event. On the other hand, when you throw a dice, it is known as a compound event.

A tank initially contains 20 gallons of water. If water is flowing into the tank at a rate of 0.1 L/sec what is the volume of wa

IRISSAK [1]

The total volume of water in the tank after 3 mins 24.75 gallons.

<h3>New volume of water in the tank</h3>

The new volume of water that entered into the tank is calculated as follows;

V₁ = 0.1 L/sec x (3 x 60 s)

V₁ = 18 L

<h3>Volume of water in liters to gallon</h3>

1 liter = 0.264 gallons

18 Liter = ?

= 18 x 0.264

= 4.75 gallons

<h3>Total volume of water in the tank after 3 mins</h3>

V = 20 gallons + 4.75 gallons

V = 24.75 gallons

A sail in the form of a right triangle the angle at its lower edge is 55 what is the size of the angle formed at the top of the

Mars2501 [29]

Answer:

The size of the angle formed at the top of the sail is 35.

Step-by-step explanation:

We know that the sum of all angles inside a triangle must be 180. This is a rule.

So we know that a right triangle is called like that because one angle is a 90-degree angle.

Then we have that:

180 = right angle + lower edge angle + angle top of the sail

180 = 90 + 55 + angle top of the sail

Solving for 'angle top of the sail' we have:

angle top of the sail = 180 - 90 - 55 = 35

The size of the angle formed at the top of the sail is 35.

Identify is this is percent increase or percent decrease, then calculate percentage

<em>Last year the chess club had 30 members. This year the club has 24 members. </em>

Last year, the chess club had 30 members. This year, the club has 24 members. Since this year had less than last year ( 30 > 24), the percent will be decreasing.

To find the percent decrease, you have to use the following formula.

$\frac{Difference}{Original} \times 100$

Difference refers to the difference between the two numbers, 24 and 30. The difference between 24 and 30 is 6. Original refers to the original number, which is last year's amount of members in the chess group. Therefore, original = 30.

Substitute the numbers into the formula.

$\frac{Difference}{Original} =\frac{6}{30} =0.2$

To convert the decimal to a fraction, multiply the decimal by 100.

$0.2 \times 100 = 20 \%$

The answer is the number of chess members decreased by 20%.

____

Since I started off by identifying whether it was decreasing or increasing, I did the work a bit differently. When finding the difference, you would usually subtract 30 from 24, which results in -6. Above I used 6, but if you used -6, you would end up with a result of -20%, which means it decreased by 20%. They bot end up with the same result, but you don't always have to first identify whether it's decreasing or increasing.
