Answer:
B. 40/61
Step-by-step explanation:
There are 40 spots out of the 61 in the lot with numbers greater than or equal to 22. The probability of choosing one of them at random is 40/61.
_____
<em>About the answer choices</em>
61/21 and 61/40 are both numbers that are greater than 1. A probability is always a number between 0 and 1 (inclusive), so these answers can be rejected immediately.
There are 21 spots with numbers less than 22, so 21/61 is the probability of choosing one of those. That is not what the question is asking for.
We get all these to have the same denominators for all the fractions.
2*2/9*2 = 4/18
1*2/9*2 = 2/18
1*3/6*3 = 3/18
Now we can add all the numerators.
4/18 + 2/18 + 3/18 = 9/18
Simplify our answer by dividing both numbers by 3, then by 2.
9/3 and 18/3 = 3/6= 1/2
Our final answer is 1/2
The corresponding sides of the model and the actual bridge are in proportion because the two solids are similar.
The scale factor from the model to the actual bridge is 5/25 = 6/30 = 8/40 = 1/5.
Answer: 1/5
You need to multiply 30 by 6 so 30times6 =your answer
As the three longitudinal lines are parallel:
angle 4 = 5 = 6 = 82 degree (corresponding angles) = 9 = 8 = 7 = 82 degrees (vertical angles)
and
angle 11 = 180-82= 98 degrees (linear pair)
so:
angle 10 = 11 = 12 = 98 degrees (corresponding angles) = 3 = 2 = 1 = 98 degrees (vertical angles)
.
hope you got it
