Answer:
x = 19cm
Step-by-step explanation:
use pythagorean theorem:
a² - c² = b²
10² - 22² = b²
100 - 484 = b²
384 = b²
√384 = b
19cm = b or x

Equation: 6.05n=12.4=
Answer:
7200 people
Step-by-step explanation:
Let's say x amount of people tried out.
After round 1: 1/2 x are left.
After round 2: 1/3 (1/2 x) are left
After round 3: 1/4 (1/3(1/2 x))) are left
Each time we multiply by the fraction that are left. By the end we will have
1/6(1/5(1/4(1/3(1/2 x))))
So to find it multiply the denominator out:
To find x, we set it equal to 10.
Answer:
Step-by-step explanation:
in quadrant 1 cos and sec are positive.
cos(θ)=√(1-sin²θ)=√(1-(12/13)²)=√((169-144)/13²)=5/13
secθ=13/5
