Variables: x and y
Coefficients: 5 and 2
Constants: 4
Exponents: 2 (if 3y is being squared)
So there are 50 teens total
16% have no sibblings
so we must find 16% of 50
16%=16/100=0.16
'of' can be translated as multiply so
0.16 times 50=8
there were 8 teens who have no sibblings
Answer:
i think is probably 70 sec or 75
Step-by-step explanation: idk
Okay,
so first you gotta know that cos(90-x) is equal to sinx and sin(90-x) is equal to cosx!!
Now all you gotta do is replace the cos(90-x) to sinx in the numerator and sin(90-x) to cosx in the denomenator inorder to make the numerator all into sin and denomenator all into cos.
After that, open up the brackets and solve...
At the end you'll hopefully get something like this :( 1+sin90 ÷ 1+cos90 )
And since sin90 is 1 (put it in the calculator!) and cos90 is 0, you'll get 2÷1 which is equals to 2!!
Hope this helped! :)
The ratio is 1:5 tbh or that’s what I think ahahahah
