We believe that the angles are in quadrant 1.
<span>sin(6m-8) = cos (2m)
</span>⇒ 6m-8 = 90 - 2m
<span>
6m + 2m = 90 + 8
8m = 98
m = 98 / 8 = 12.25
</span>
Answer:
Let the test scores be x1, x2, x3, x4
(x1 + x2 + x3)/3 = 88
x1 + x2 + x3 = 264
(x1 + x2 + x3 + x4)/4 = 90
264 + x4 = 360
x4 = 360-264
x4 = 96
Therefore he should get 96 marks in his 4th test to raise his mean test score to 90
The mean score is the total of all scores divided by the total no. Of tests
Hope this helps!
Solve within parenthesis first so .49 +.045 =.535 so then divide by five which is .107
The answer is =
Any number divided by itself = 1
Whatever% of anything, is just (whatever/100) * anything.
the syrup is going to be 5lbs total, that includes the sugar in it as well as the water mix.
keeping in mind that the syrup will be a 1.5% syrup, namely 1.5% of it will be sugar, the rest just water then, how much is 1.5% of 5?
well, is just(1.5/100) * 5 or 0.075, namely lbs.
so, 0.075 lbs will be sugar and the rest water, the rest will be 5 - 0.075, or 4.925 lbs.
