Answer:
80 m/s
Step-by-step explanation:
Hi there.
A prime number is a number that cannot be divided into a smaller whole number aside from 1 and itself. An example would be 3; it cannot be divided into a smaller whole number unless it was divided by itself.
Let's look at the factors of 63:
1 * 63
3 * 21
7 * 9
On the left side of our multiplication table above, we have the list of prime numbers (1, 3, and 7). To the right, we don't (63, 21, and 9).
From our answer choices, we have B.) 7 included, so that is your answer.
To debunk the right side of the table:
63 can be divided into smaller numbers, which are listed above.
21 can be divided into 3 and 7.
9 can be divided into 3 and 3.
I hope this helps!
Answer:
78º
Step-by-step explanation:
<u>Note</u> : -
In mathematics, the reference angle is defined as the acute angle and it is measuring less than 90 degrees. It is always the smallest angle, and it makes the terminal side of an angle with the
x - axis.
<u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>1</u> : -
Find where 192º lies in which quadrant.
192º lies in 3rd quadrant ( between
180º and 270º )
<u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>2</u> : -
Subtract : 270 - 192
270 - 192 = 78º
( Since, 192º is greater than 180º, is subtracted from 270º )
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u> : -
78º is the reference angle for 192º.
So
10^x times 0.02=20
divide both sides by 0.02
10^x=1000
10^3=1000
answer is 3rd power of 10
