Mathematics
1 answer:
frozen [14]3 years ago
4 0

Answer:

62.5%

Step-by-step explanation:

Total number of people at the concert = 10000

Number of adults = 6250

Percentage of adults = number of adults/ total number of people at the concert x 100%

That’s

6250/10000 x 100%

0.625 x 100%

62.5%

62.5% of the people at the concert are adults

trasher [3.6K]

Answer:

The first step is to ensure that all of the fractions have a common denominator.

3\dfrac{1}{3}+\left( -2\dfrac{1}{4} \right) + 1\dfrac{5}{6}= \\\\3\dfrac{4}{12} - 2\dfrac{3}{12} +1 \dfrac{10}{12}= \\\\1\dfrac{1}{12}+1\dfrac{10}{12}= \\\\\boxed{2\dfrac{11}{12}}

vivado [14]

Answer:

≈ 33°

Step-by-step explanation:

So, first, you can draw a visual. Refer to the image attached below:

Using this info, you can use trigonometric ratios. Recall that:

tangent = opposite side/adjacent side

sine = opposite side/ hypotenuse

cosine = adjacent side/hypotenuse

You can clearly see that you have an opposite side and a given hypotenuse. This means we'll be using sine.

So:

sinX = \frac{150}{275}

However, we're not trying to find sinX, we're trying to find X.

So we would have to use inverse sine, which would then be:

X = sin-1 (\frac{150}{275} )

Put this into your calculator, and:

X ≈ 33.05573115...
