By pythagoras
53^2 = h^2 + 45^2 where h is the height of the television.
h^2 = 53^2 - 45^2 = 784
h = sqrt 784 = 28 inches Answer
Answer:
5/48, 1/2 and 3/4
Step-by-step explanation:
You need to make a common denominator for all the numbers first.
1/2 is equal to 24/48
-multiply both sides by 24 because 48 divided by 2 is 24
3/4 equals 36/48
-multiply both sides by 12 because 48 divided by 4 equals 12
so you get:
24/48 (1/2)
36/48 (3/4)
and 5/48
now you order them:
5/48
24/48
36/48
and then you change them back to their original form:
5/48
1/2
3/4
This one was a little more complex. I factored in 6 to get rid of fraction since standard for is just integers. Then I followed the steps from before.
Answer:
22) 119
24) 15
Step-by-step explanation:
22) 61 + b = 180 <-- supplementary because on the same line
b = 119 <-- subtracted 61 from both sides
24) 87 + (6x + 3) = 180 <-- supplementary because on the same line
87 + 6x + 3 = 180 <-- take out parantheses
90 + 6x = 180 <-- add like terms
6x = 90 <-- subtracted 90 from both sides
x = 15 <-- solve for x by dividing 6 from both sides
