B. 90/360, because this is 1/4 from circle. It's even shown in the picture.
Example: If you take a protractor at 180°, then if you mirror it, then 360° will comeout, i.e. a circle.
Answer:
(√3 tan x + 1) / (√3 - tan x)
Step-by-step explanation:
Answer:
21, 28, 36
Step-by-step explanation:
1 + 2 = 3
3 + 3 = 6
6 + 4 = 10
10 + 5 = 15
Next three terms,
15 + 6 = 21
21 + 7 = 28
28 + 8 = 36.
If it takes a ball to roll 12 meters per sec, and asks how far it will roll for 3 seconds you would multiply 12 and 3 getting 36.
The ball will roll 36 meters for 3 seconds
Answer:
x = 20
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
1 3/4 14
------------ = --------
2 1/2 x
where x is the unknown number.
Converting the mixed numbers to improper fractions, we get:
7/4 14
------ = -----
5/2 x
Here there are two numerators and two denominators. Multiplying all four quantities by 4 will remove some of the fractions:
7 56
------ = -------
10 4x
Cross multiplying, we get:
28 x = 560, or x = 20
