Answer:
C. (-5, 3)
Step-by-step explanation:
Point C is currently (5,3).
If it is reflected over the y-axis, that means while the <em>y-coordinate stays the same, the x- coordinate is negative of what is was before</em>.
C is the only answer that keeps the y-coordinate constant, so just by looking at that, we can say that the answer is C.
1st half life: 195/2 = 97.5 g
2nd half life: 97.5/2 = 48.75 g
3rd half life: 48.7/2 = 24.375 g
4th half life: 24.375/2 = 12.1875 g
5th half life: 12.1875/2 = 6.09375 g
or you can do
195(2)^(-5) = 6.09375
** rounded to nearest gram = 6 g
Answer:
A. x + y = 34; 10x + 15y = 410
Step-by-step explanation:
Jody's total hours will be the sum of the hours spent on each job:
x + y = 34 . . . . . total hours
Jody's total earnings will be the sum of the earnings from each job:
10x +15y = 410 . . . total earnings
So, the system of equations is ...
- x + y = 34
- 10x + 15y = 410
Answer:
117.8
Step-by-step explanation:
i used heron's formula
√s(s-a)(s-b)(s-c)
s= (20+16+33)/2 = 34.5
√34.5(34.5-20)(34.5-16)(34.5-33)
= 117.8
