Answer:
Each interior angle = 180° -60° = 120°
Step-by-step explanation: We know that the three angles in a triangle, add up to 180°, and all the three angles are 60° in an equilateral triangle. The total number of angles of an enclosed space is 180° (n-2) where in is the number of sides.
A hexagon has six sides, so: s= 180° (6-2)
s= 180° x 4
s= 720°
now since in a regular shape, each interior angle is equal. We just divide the total interior angle with a number of sides
6.
720° divided by 6 is equal to 120°
Answer: A) and B)
Step-by-step explanation:
So for the first one, a closed circle means that it includes the point and the graph proceeds in the positive direction. So it will be whatever number it starts on in the x axis is less than or equal to x.
The second one you find the distance it moves each second.
You do this by distance over time d/t. Then you divide the 408 by that number.
So 264cm / 11 seconds = 24 cm/sec
Then 408cm/ 24cm per sec = 17s
Answer:
D
Step-by-step explanation:
even
4(-x^3) = 4x^3
-4x^3 = 4x^3 (false)
odd
-4x^3 = 4(-x^3)
-4x^3 = -4x^3
500 (the current collection) + 10 (the weekly addition) x 20 (weeks to add)
500 + 10*20 (Multiplication comes before addition)
500+200
700
If 55% of the student body are boys, then 45% are girls.
35% of boys are on the honor roll, so 35% of 55% are on the honor roll.
40% of girls are on the honor roll, so 40% of 45% are on the honor roll.
So now we need to find each of those numbers...
35% of 55% =
.35 * .55 = .1925 multiply by 100 to convert to percent
19.25% of boys (in the student body) are on honor roll
40% of 45% =
.40 * .45 = .18 multiply by 100 to convert to percentage
18% of girls (in the student body) are on honor roll
Add the two together to get the total percentage of student body that is on the honor roll...
19.25% + 18% = 37.25%
Round to the nearest percent
37%
