Step-by-step explanation:
clockwise 270°
B.
clockwise 360°
C.
counterclockwise 180°
D.
counterclockwise 90°
Answer:
C. counterclockwise 180°
Step-by-step explanation:
Hi! A and B are definitely not the right answers, because that’s basically rotating it forward even more. Rotating a polygon in Quadrant II 370 degrees clockwise is like rotating it 99 degrees counterclockwise, because the next 90 degrees you were to rotate it, it would be in it’s original position. The answer is C.
Answer:
Step-by-step explanation:
Let us translate it step by step:
m reduced by 3 is subtracting from m, therefore: m - 3
Then the quotient of that and 5 is the division or fractions of m-3 over 5:
That is the expression for the quotient of the quantity m reduced by 3 and 5.
Answer:
30
Step-by-step explanation:
First, find out how many half-lives have passed. Divide the number of minutes by the length of a half-life.
20÷10=2
2 half-lives have passed.
Now figure out how much nitrogen will be left after 2 half-lives have passed. Multiply the starting amount of nitrogen by
1/2
a total of 2 times.
120x1/2 1/2=30
That calculation could also be written with exponents:
120x(1/2)2=30
After 2 half-lives, the amount of nitrogen left will be 30 grams.
