Answer:
4
Step-by-step explanation:
Both triangles are the same shape, just to different scales. In order to find out the length of side AB in triangle ABC, you have to find out the length of side PQ in triangle PQR and how much bigger than side AB is.
You can tell that sides AC and PR are similar, and 30/5 is 6. You see also that sides BC and QR are similar, and 42/7 is also 6. We have now discovered that triangle PQR is 6 times bigger than triangle ABC.
So now, to find the length of the missing side, we have to shrink side PQ by 6. 24/6 is 4. Therefore, the length of side AB is 4.
Answer: 2x - 1
(9x - 7) - (7x - 6)
9x - 7 - 7x + 6
2x - 1
Answer: Hello mate!
Two independent events, mean that the fact that, if the event A occurred, this has no effect in the probability of the event B to occur after.
For example, a coin flip.
The first result has no effect on the next result.
Then the notation P(A/B) is the probability of the event A when the event B occurred before, but as we know, the fact that the event B occurred before has no effect in it; so:
P(A/B) = P(A) = 0.30
Answer:160 miles
Step-by-step explanation:
Since one inch is equal to 20 miles, multiply 8 by 20. 8*20 = 160
Answer:
12
Step-by-step explanation:
Assume the hidden number is x;
So, if x*12= 16,836
Next, divide both sides by 12 to solve for x;
x= 16,836 / 12
x= 1,403
So the number hidden by spilt ink is 1,403.
Next, to answer the question, divide 16,836 by the hidden number,1403;
16,836 / 1403 = 12
Therefore, it will be equal to 12 which is basically the reverse of the first equation.
