Answer:
x ≈ 66.73
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan27° = 
= 
= 
( multiply both sides by x )
x × tan27° = 34 ( divide both sides by tan27° )
x = 
≈ 66.73 ( to 2 dec. places )
The probability to be inside the large square is 3/10 and the probability to be inside the small square is 7/10
Answer:
5 years
Step-by-step explanation:
Formula to calculate simple interest
<h3>A = P(1 + rt)</h3>
Where:
<em>A = Future amount = 2(100)</em>
<em>P = Principal Amount = 100</em>
<em>r = Rate of Interest per year in decimal</em>
<em>r = R/100 = 20/100 = 0.2</em>
<em />
To find,
t = Time Period
Put value in the formula
200 = 100(1 + 0.2t)
200/100 = (1 + 0.2t)
2 = (1 + 0.2t)
2 - 1 = 0.2t
1 = 0.2t
1/0.2 = t
t = 5 years
So, it will take 5 years to double money.
Answer:
V = 3533
Step-by-step explanation:
Volume of a cylinder is given by
V = pi r^2 h
Using 3.14 for pi
V = (3.14) (7.5)^2 * 20
V = 3532.5
To the nearest whole number
V = 3533
