Answer: 35.4 feet.
Step-by-step explanation:
Given data:
Height of the roof = 24 feet
Height of the ladder = 26 foot
Solution:
c^2 = a^2 + b^2
a = 24
b = 26
c^2 = 24^2 + 26^2
c = √576 + 676
c = √1252
c = 35.4 feet
The foot of the ladder is 35.4 foot away from the top of the ladder.
K = y/x OR y = kx
hope it helps!
Answer:
t = 35/12
Step-by-step explanation:
t - 7/4 = 2/5 t
t = 2/5 t + 7/4
t - 2/5 t = 7/4
t*(1-2/5) = 7/4
t*3/5 = 7/4
t = (7/4)/(3/5)
t = 7*5/4*3
t = 35/12
Question 2: The answer is A. 90, 45, 45 because one angle is a right angle which is always 90 degrees and the two remaining angles are the same. Also, all triangles have to have a total amount of 180 degrees when all angle-degree-measurements are combined, which leaves A as the only possible answer.
Question 3: The answer is D. To solve this question you simply multiply all the dimensions of the triangular prism together. That would be: 10 x 14 x 8 = 1,120 in squared
Question 4: Sorry, didn't get this one :(
Question 5: The answer is B. 4pi. Sorry, don't have a good explanation for this one, but I'm pretty sure it is correct.
Question 6: Can't see the question, so I can't help you :(
Question 7: The answer is A. 5 feet. Using the power of elimination you can conclude that the three other options to the answer are improbable.
Question 8: The answer is B. 180 - x. To get this you need to know that 180 degrees is a flat line angle. Since angle x and angle y stem from the same two flat lines intersecting diagonally, you can determine the 180 - angle x would equal angle y.
Answer:
Part #1: 13/15
Part #2: 11/45
Part #3: 23/45
Step-by-step explanation:
Part #1: So add the total amount of coins: 4 + 7 + 12 + 22 = 45
Since the only coins that are at most $1 are: The $1 coins, 50 cent coins, and the 20 cent coins. That is a total of 7 + 12 + 20 = 39
39/45
13/15
Answer: 13/15
Part #2: Since the only coins that are $1 or $2: The $1 coins and the $2 coins. That is a total of 4 + 7 = 11
11/45
Answer: 11/45
Part #3: Since the only coins that are at least 50 cents: The $1 coins and the $2 coins and the 50 cent coins. That is a total of 4 + 7 + 12 = 23
23/45
Answer: 23/45
