Answer:
21.068 rounded to the nearest 10th is 21.1
Step-by-step explanation:
To round a number to the nearest tenth , look at the next place value to the right . If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
Answer:
n(n - 3)/2
Step-by-step explanation:
We are told that;
A square has 4 sides and 2 diagonals.
Now, a pentagon will have 5 sides and 5 diagonals
A hexagonal when drawn will have 6 sides and 9 diagonals
Thus, we see that;
When n = 4, d = 2
When n = 5, d = 5
When n = 6, d = 9
Using combination, we will find number of pairs of 2 vertices that can possibly be formed from n-vertices. Thereafter we will subtract n from that since it's neighboring vertices can't combine with the current one.
Thus, we have;
C(n, 2) - n
This gives s;
(n(n-1)/2) - n
Simplifying this gives;
(n(n - 1) - 2n)/2
>> (n² - n - 2n)/2
>> (n² - 3n)/2
>> n(n - 3)/2
Answer:
4 carrots 12 radishes
Step-by-step explanation:
c=carrors
3c=radishes(3 times the carrots)
c+3c=16
4c=16
c=4 (four carrors)
4*3=12 (12 radishes)
Answer:
- Quadrant I
- Quadrant IV
Step-by-step explanation:
Angles are measured counterclockwise from the positive x-axis, so after 360°, the terminal side starts again in Quadrant I.
1. Since the angle is between 360° and 450°, its terminal side is in Quadrant I.
2. When an angle represents a clockwise rotation from the positive x-axis, it is given a negative angle measure. After -360° the terminal side starts again in Quadrant IV. Since the angle is between -360° and -450°, its terminal side is in Quadrant IV.
