Answer:
700 teens
Step-by-step explanation:
If five out of 7 teens do homework every night
There are 980 teens
How many out of 980 teens would do homework every night?
Firstly divide 980 teens by 7
Which is 980/7=140
Next is,
Out of 7 teens, there are 5 who do homework every night
So, multiply 140 by 5
140×5=700 teens
This means, the reasonable prediction of teens who do homework every night out of 980 is 700 teens
Note that sin 45 deg = opposite side / hypotenuse.
1 7sqrt(2)
Here, sin 45 deg = ----------- = --------------
sqrt(2) x
Cross multiplying, we get x = 7 [sqrt(2) ]^2 = 7(2) = 14 (answer)
Answer:
Sine, cosine and tangent formulas are used in RIGHT triangles. So you have one 90 degree angle and two acute angles that add up to 90 degrees (they are complimentary). So the cosine of one angle would be the same as the sine of the compliment to that angle... and vice versa. To answer this question, sin 81 = cos 9, since 81 and 9 are the two acute angles of the triangle and they both add up to 90 degrees. "Cos 9" is the answer when you wish to write "sin 81" in terms of "cosine."

The solution to the problem is as follows:
The savings left is just $72 - $8 = $64.
Therefore, the ratio is $64 : $72 = 8 : 9.
