Answer:

Choice B. 16 feet.

The height of the tree is 16 ft

Step-by-step explanation:

Similar Triangles

Similar triangles have their corresponding side lengths proportional by a fixed scale factor.

We are given the drawings of a tree and a wall and it's assumed both triangles are similar. We need to find the scale factor and find the height of the tree.

Comparing the corresponding distances from the viewer to the base of the tree and the base of the wall, we can calculate the scale factor as 24/6=4.

Applying the same factor to the height of the model, we get the height of the tree is 4*4 = 16 ft.

Choice B. 16 feet

The height of the tree is 16 ft

Michael wants to take French or Spanish, or both. But classes are closed, and he must apply and get accepted to be allowed to en

Brums [2.3K]

Answer:

80%.

Step-by-step explanation:

Given the following probabilities:

P(Micheal Being admitted to French), P(F)=50%
P(Micheal Being admitted to Spanish), P(S)=50%

In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:

P(Micheal Being admitted to BOTH French and Spanish), $P(F \cap S)=20\%$

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).

Probability of either A OR B = $P(F \cup S)$

From Probability Theory:

$P(F \cup S) = P(F)+P(S)-P(F \cap S)\\P(F \cup S) =50+50-20\\P(F \cup S) =80$

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.

What is the percent of change?

Xelga [282]

Percent means parts out of 100
x%=x/100

find change
10 to 60=50 (60-10=50)

percent change=change/originla
original=10
change=50
50/10=x%
5/1=x/100
multiply both sides by 100
500=x

answer is 500%
