Answer:
Step-by-step explanation:
Yes
Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
Answer:
RS = 2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
RS² + RT² = TS² , that is
RS² + 6² = 8²
RS² + 36 = 64 ( subtract 36 from both sides )
RS² = 28 ( take the square root of both sides )
RS =
=
= 2
≈ 5.3 ( to 1 dec. place )
The answer is B. A reflection across the x-axis.
Yes it will. For every one hour, the train travels 170 miles. That’s the rate of change/ the ratio-> 1:170
