Answer:
x=27
y=9√3
Step-by-step explanation:
Since the angles in a triangle add up to 180, and we know that one angle is 30 and the other 90, the last angle is (180-90-30)=60°. Then, we can identify this as a 30-60-90 triangle, so the side opposite the 90 degree angle is a value of 2a, the side opposite the 30 degree one a, and the side opposite the 60 degree one a√3. We know 2a to be 18√3, so y, the side opposite the 30 degree angle, is a (18√3/2=9√3) and x, the side opposite the 60 degree angle, is a√3, or 9√3*√3=9*3=27
The answer is b hope is the correct one
The given inequality is:
-5c + 2 ≤ 27
Subtracting 2 from both sides, we get:
-5c + 2 - 2 ≤ 27 - 2
-5x ≤ 25
Dividing by 5 on both sides we get:
- x ≤ 5
Multiplying by -1 we get:
x ≥ 5
Remember that multiplying or dividing by a negative number changes the direction of inequality symbol.
From the given options, the second graph correctly represents this solution.
Answer:$249895.46
Step-by-step explanation:
Well, if 2250 dollars increase by 17% every year for 30 years, then it will be 2250*(1.17)^30
which would be $249895.46
so if you could increase money by 17% every year, 2250 dollars now will be worth a lot in 30 years!
<u><em>Answer:</em></u>
Emma is 111 months old
<u><em>Explanation:</em></u>
We know that one year has 12 months:
<u>Therefore:</u>
9 years have 12*9 = 108 months
0.25 of a year = 0.25 * 12 = 3 months
<u>Since Emma is 9.25 years old, therefore:</u>
Emma is 108 + 3 = 111 months old
Hope this helps :)
