Answer:
40
Step-by-step explanation:
dilated by a factor 8 => the area of a rectangle would be (8x8) times of the origin,
5/8 × (8x8) = 5/8 × 64 = 40 ft²
It’s 16, you get the answer by counting the outside ones
Answer:
38
the angles need to add up to 180 degrees because they are supplementary.
Do 180-142=38
Hope this helps. Supplementary means when you add the angles together they add up to 180.
Step-by-step explanation:
First, work out the difference(increase) between the two numbers you are comparing. So, the difference would be <em>100-80</em>, which will equal <em>20</em>.
Then, divide the increase by the original number and multiply the answer by 100. So, that would be <em>20÷100</em>, which would be <em>0.2</em>, then it would be <em>0.2⋅100</em>, so back to <em>20</em>.
The percent of increase should be 20.
The probability that either the girls' or boys' team gets a game is 0.85
Step-by-step explanation:
Step 1:
Let P(G) represent the probability of girls team getting a game and P(B) represent the probability of the boys team getting a game.
P(B ∪ G) represents the probability of either girls and boys team getting a game.
P(B ∩ G) represents the probability of both girls and boys team getting a game.
Step 2:
It is given that P(G) = 0.8, P(B) = 0.7 and P(B ∩ G) = 0.65
We need to find the probability of either girls or boys team getting a game which is represented by P(B ∪ G)
Step 3:
P(B ∪ G) = P(B) + P(G) - P(B ∩ G)
= 0.8 + 0.7 - 0.65 = 0.85
Step 4:
Answer:
The probability that either the girls' or boys' team gets a game is 0.85
