C, I’m pretty sure
Why do I have to write 20 words for this? This is why I’m rambling.
recall that a/b to decimal is just a ÷ b, so 2/9 is just 2 ÷ 9.
check the picture below.
Answer:
72°
Step-by-step explanation:
The cookie has a shape of a circle. A circle is the locus of a point such that its distance from a point (center) is always the same. The sum of angles around the circle center is 360°.
Let x be the measure of the angle in each slice. Therefore the sum of the total 5 slice is:
x + x + x + x + x = 360
5x = 360
Dividing through by 5:
5x / 5 = 360 / 5
x = 72°
Each slice has an angle measure of 72°
Answer:
x = 1
Step-by-step explanation:
2x + 1 = -1
2x = -1 - 1
2x = -2
x = -2 ÷ -2
x = 1
You can either do;
1. 90(2) = 100(2)
180 = 200
In 3 minutes, they can write 200 words. So now we can divide by 3.
3/3 = 1 minute
200/3 ≈ 66.666
or
2. 90/3 = 30 secs
100/3 ≈ 33.333
30(2) = 1 minute
33.333(2) ≈ 66.666
Either way, the admin assistant can write 67 words per minute. (Rounded to the nearest whole)
