Answer:
$ 8.74
Step-by-step explanation:
After Yu spends the 2.80, he is left with 17.49
Half of 17.49 is 8.74
Convert "inches" to "feet" here. 30 in 1 ft 30
--------- = --------- = --------- ft
1 12 in 12
Now find the ratio of (30 ft / 12) to 9 ft:
30 ft
------
12 30
==== = ----------- Reduce this fraction; one way would be to
9 ft 12(9) write 30/9 as 10/3:
30 10
------- = ------------ = 5/18 (answer)
12(9) 12(3)
Answer:
$15
Step-by-step explanation:
If you have 2 smoothies for $5 you need to take 5 times 3. Cause we have split the 6 into 3 cause you get 2 smoothies for $5.
To change 3 1/4 to an improper fraction, we must transfer the mixed number, which contains a fraction (1/4) and whole number (3), to just a fraction.
To do this, we must transfer 3 to a fraction with the denominator being 4
We can do 3 x 4 to find the number on top.
3 x 4 = 12
To check to make sure we did it right, we can do 12 / 4 which = 3 (√ check!)
Then we add 1/4 to 12/4 to get B. 13/4
Apply the Pythagorean Theorem.
a^2 + b^2 = c^2
The largest side is always C.
so 8^2 + 15^2 = 17^2
64 + 225 = 289
The equation true is so it is a right triangle
