Each side is 8 inches. To find volume, you do length x width x height. A cube has all equal sides. 8x8x8=512
Answer:
b. 1/2, -1/2
Step-by-step explanation:
)
It would be B. y = 7 because it says write the equation for the VERTICAL LINE which is the y axis. Since the points are (-7, 7), it is the same thing as (x, y) the positive 7 is where the y is, so it would be y = 7
Answer:
102 ≤ heart rate ≤ 183.6
Step-by-step explanation:
... lower limit ≤ heart rate ≤ upper limit
Put 16 where "a" is and do the arithmetic.
... lower limit = 0.5(220 -16) = 102
... upper limit = 0.9(220 -16) = 183.6
Then the inequality is ...
... 102 ≤ heart rate ≤ 183.6
