Spotlight Dance increased the number of dancers on its competition team. Last

Mathematics
1 answer:
Nana76 [90]3 years ago
3 0

Answer:

80%

Step-by-step explanation:

To find percentage increase, we use the following formula:

Percentage Increase = \frac{New-Old}{Old}*100

Here

New means the latest value (which is 18 dancers)

Old means the previous value (which is 10 dancers)

The Multiplication by 100 is to convert the decimal answer to percentage.

So, we have:

New = 18

Old = 10

Now we substitute and find:

\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80

So, there was an increase of 80%

A wall with a height of 20 feet is braced with a support post that forms a 30 degree angle with the top of the wall. What is the
dexar [7]

The length of the support post is 40 ft.

<u>Solution:</u>

Given, the height of the wall is 20 ft; support post forms 30 degree

Refer the attached image

Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and \angle A is 30 degree (\theta) and AC is the length of the post.

To find: The length of the post (AC)

we know the formula, sin\theta=\frac{opp}{hyp} (trigonometric formula)

On substituting the values we get,

\Rightarrow sin(30^{\circ})=\frac{20}{AC}

The value of sin 30 degree is 0.5

\Rightarrow 0.5=\frac{20}{AC}\rightarrow AC=\frac{20}{0.5}\rightarrow AC=40 ft

A place kicker in pro football has a 77% probability of making a field goal over 40 yards, and each attempted field goal is inde
Mice21 [21]

The probability that the team will win the sport is 77%.

Given that an area kicker in pro football incorporates a 77% probability of creating a field goal over 40 yards and every attempt field goal is independent.

Probability is how something is likely to happen. The probability of a happening is calculated by the probability formula by simply dividing the favorable number of outcomes by the overall number of possible outcomes.

So, his team will win the sport if he makes a goal otherwise loses.

Therefore, the Probability that his team will win the sport P[E] =P[making a field goal]

P[E]=77%

Hence, the probability that the team will win the sport when making a field goal is 77%.
