Well, let's see how it'll effect your grade...
75% ÷ 90% = 0.83
0.83 x 100 = 83%
It would effect your grade by 7 percent, lowering it to 83%
I hope this helps!
According to the Triangle Midsegment Thereom, if the midsegment of a triangle is parallel to a side of the triangle, then the midsegment is half the length of side it is parallel to, therefore...
45=(7x+13)/2
And after that, you continue to solve the problem using Algebra
90=7x+13
77=7x
11=x
I hope this answer was helpful! :)
Answer:
t ≥ 96 test score must be 96 or greater
Step-by-step explanation:
Let t - score on his third test
(75 + 81 + t) ÷ 3 ≥ 84
⇒ (75 + 81 + t) ≥ 84 x 3
⇒ (75 + 81 + t) ≥ 252
⇒ 156 + t ≥ 252
⇒ t ≥ 252 - 156 ≥ 96
Try this option:
1) q: What is the slope of the line and what does it mean in this situation?
a: the slope is 2.5 and it means '<u>ammount of the rain is 2.5 mm. per hour</u>'.
2) the slope of the line is '<u>2.5</u>'
3) this means that '<u>2.5</u>' mm. of the rain falls every '<u>1</u>' hour.
Sin(a+b)=sin(a)cos(b)+cos(a)sin(b).
Let a=42 and b=17 so sin(42+17)=sin59.
