Answer: 84.09%
Step-by-step explanation:
1. 220-30=? ?=185
2. Divide 185 by 220 (as a fraction, 185 out of 220 is 185/220 which also means divide) 185 divided by 220 is about 0.8409
3. Multiply 0.8409 by 100 (since there is two zeros in 100 we can move the decimal to the right twice which gets you 84.09
Given;
ABCDE is similar to VWXYZ
so, the corresponding segments are proportional
We need to find the length of XY
XY is corresponding to CD
CD = 1.2 cm
Finding another two corresponding sides
DE = 3.2 cm , YZ = 4 cm
so,

So, the length of XY = 1.5 cm
If two events are independent, then P(A and B) = P(A) x P(B).
In your situation, you need to solve 0.185 = 0.25 x P(B).
Can you take it from there?
Answer:
83.33%
Step-by-step explanation:
300 - 50 = 250
250/300 = 0.8333 or 83.33%
Let t is the amount of time that the gas is leaking (hour), g is the total of the gas leak.
