Answer:
9 Is the answer.
Step-by-step explanation:
So you have to substitute these values in to the equation and solve.
3(-2) +5(11-8)
-6+5(3)
-6+15
9
Answer:
28 4/9oz.
Step-by-step explanation:
I'd convert this to ounces. A gallon is 128oz.
2x128=256
Now, divide by 9.
256/9≈28.44oz., or 28 4/9 oz.
Answer:
0.03 feet
Step-by-step explanation:
d = 0.03r² + r
When d = 0: 0.03r² + r = 0
r(0.03r + 1) = 0
∴ r = 0
When r = 0: d = 0.03 feet
Using proportions, the approximate length of time, in years, for the watch to lose exactly 24 hours is:
(d) 240.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
24 hours have 24 x 3600 = 86400 seconds, hence the <em>rule of three</em> is given by:
One second - 1/365 year
86400 seconds - x years
Applying cross multiplication:
x = 86400/365
x = 240.
Hence option D is correct.
