Why does sin(15) always equal the same number, no matter how big or small you make the triangle.

This is because sin is opposite over adjacent and this ratio will always be the same in every triangle because a triangle must always add up to 180.

Sin is equal to the same number, no matter how big or small you make the triangle because the sine of the angle is equal to the opposite side divided by the hypotenuse.

Vikentia [17]

Answer:

6 m

Step-by-step explanation:

The sine of an angle is the ratio between the opposite side of the angle and the hypotenuse.

Hence, sin 30° = $\frac{a}{c}$

= $\frac{a}{12}$

a = 12sin30°

a = 6m

Pls help ????????????

Answer:

let the missing values be a , b , c ,d and e

So the mean of these values is $ 2225

(a + b + c + d + e + 1900 + 2300 + 3000)/8 = 2225

a + b + c + d + e + 7200 = 2225*8

a + b + c + d + e = 17800 - 7200

a + b + c + d + e = 10600 -------------------- let this be our first equation

Since the range is 3000 and the data is already in increasing order:

3000 - a = 2100

a = $ 900 --------- one down, 4 to go

Now lets get another equation through Median:

So the median value is 2450, since median is the middle value when the given set is written in increasing or decreasing order

since we are already given the increasing order of the numbers, we will make use of that

So, since there is no middle number since there are even amount of numbers, the average of the 2 mid numbers will be the Median

so, (2300 + c)/2 = 2450

2300 + c = 4900

c = $ 2600 ---------------------- two down, 3 to go

Now we will try to get another equation through mode

We are given that the mode of the numbers is 2900

we will take some help from the first equation for this part

a + b + c + d + e = 10600

900 + 2600 + b + d + e = 10600

b + d + e = 10600 - 3500

b + d + e = 7100

Since the mode is 2900, lets check if b + d + e = 3 (2900) since that would mean that 2900 is repeated 3 times

b + d + e = 2.45(2900)

since b + d + e is 2.45 times 2900 and 2900 is the most repeated number,

we can say that 2 of the 3 values is 2900

so,

2900 + 2900 + b = 7100

e = 7100 - 5800

e = $ 1300

so the complete list is: 900 , 1300 , 1900 , 2300 , 2600 , 2900 , 2900 , 3000

Mia is 7.02576 × 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume a year has 36

Naya [18.7K]

Answer:

Number of days = 4879 days

Number of months = 162.63 months

Number of years = 13.37 years

Step-by-step explanation:

Given

Mia's age (in minutes) = $7.02576 * 10^6$

Required

Calculate age in years, months and days.

For ease of work, we'll start by converting to days.

First, it should be noted that there are 24 hours in one day

And there are 60 minutes in an hour.

This means that there are 24 * 60 minutes in a day

Number of minutes = 24 * 60 minutes

Number of minutes = 1,440 minutes

So, if number of minutes in a day is 1,440

Number of days in $7.02576 * 10^6$ minutes is calculated as follows

Number of days = $\frac{7.02576 * 10^6}{1440}$

Number of days = 4879 days

Now, we can convert this to month and year, easily.

From the question, it should be assumed that there are 30 days in a month.

If 1 month = 30 days

Then, there are $\frac{4879}{30}$ months in 4879 days

Number of months = $\frac{4879}{30}$

Number of months = 162.63 months

Converting to year

From the question, it should be assumed that there are 365 days in a month.

If 1 year = 365 days

Then, there are $\frac{4879}{365}$ years in 4879 days

Number of years= $\frac{4879}{365}$

Number of years = 13.37 years

Absolute 10.7 of percent 11

leva [86]

Answer: = 11.88

This is a 3 step / 4 show workings.

10.7 + Percentage increase = 11%

10.7 + (11% × 10.7) = 10.7 + 11% × 10.7

(1 + 11%) × 10.7 = (100% + 11%) × 10.7

111% × 10.7 = 111 ÷ 100 × 10.7

111 × 10.7 ÷ 100 = 1,187.7 ÷ 100

11.877 ≈ 11.88
