1 answer:
Answer:
1/6
Step-by-step explanation:
Number of orange crayons = 2
Total number of crayons = 2 + 4 + 1 + 2 + 3 = 12
Probability is calculated as:
Here the favorable or desired outcome is picking up an orange crayon. So number of favorable outcomes will be 2 as 2 orange crayons are available.
Total number of outcomes is 12 which is the sum of all the crayons available.
So, the probability the crayon she pulls out will be orange =

The answer is 80 ft.
Based on the diagram we know that the tree triangle and the building triangle are similar triangles where the lengths of each are proportional to the other.
The lengths of the triangle the tree makes are half of the lengths of the building triangle. So this problem can be solved using ratio and proportion:
to solve for x, all you need to do is cross multiply then divide.
The answer is then 80ft.
Another way to solve this is just by using logic. If the lengths of the tree triangle is half of the building, simply divide the lengths of the building triangle by two.
160ft/2 = 80ft.
