Answer:
45.3 grams will be left
Step-by-step explanation:
Use the formula
A = P(1 - r)^t where A is the final amount, P is the initial amount, r is the percent change as a decimal, and t is the amount of time
Plug in what we know, we are given P = 780, r = 0.163, and t = 16
A = 780(1 - 0.163)^16
Now simplify...
A = 780(0.837)^16
A = 45.25868493
A = 45.3
Answer: angle B will be 90°
Sum of the angles = 180°
All you need to do is solve it

or

When solved your answer is
0.25 or 1/4
------------------------
What I did to solve it was....
1. Divide top fraction by bottom fraction to get decimal
1 ÷ 2 = 0.5
2. Then multiply 0.5 by its self (the same as putting it to the ^2)
0.5 x 0.5 = 0.25
Answer:
x<7.5
Step-by-step explanation:
Answer:
1. Positive, 1+2=3
2. Negative, -1-2=-3
Step-by-step explanation:
If you look at both in a graphing perspective, the point (1,2) is in Quadrant I. likewise, adding 2 to the x-coordinate will also result in the point (3,2), also in Quadrant I, where the x coordinate is positive. The point (-1,2) is in Quadrant II, and adding -2 to the x coordinate keeps it in Quadrant II, where the x-coordinate is negative.
