I think this is how you do it, each triangle is 3, and the square is .5625 so 3 x 4 is 12+ .5625 so 12.5625, i hope i helped
The probability of no rain is .13 Probability should add up to 1.00 (100%)
Y =

This is because 16 needs to be added to the base amount since the teachers cost is automatically added in.
P = $1,100
r = 7.25% = 0.0725
A= P(1+r)^t
⇒ 6600 = 1100(1+0.0725)^t
⇒ 6600/1100 = 1.0725^t
⇒ 1.0725^t = 6
Use log to solve it
log(1.0725^t) = log 6
⇒ t * log 1.0725 = log 6
⇒ t * 0.0303973 = 0.7781512
⇒ t = 0.7781512/0.0303973
⇒ t = 25.599 ≈ 25.60 years
Answer:
x = 15
Step-by-step explanation:
<u>Step 1: Make an expression</u>
<em>4/6 = 10/x</em>
<em />
<u>Step 2: Cross multiply</u>
4/6 = 10/x
<em>4x = 60</em>
<em />
<u>Step 3: Divide both sides by 4</u>
4x / 4 = 60 / 4
<em>x = 15</em>
<em />
Answer: x = 15
