Answer:
Step-by-step explanation:
"Best estimate' doesn't happen automaticallly, because you have to define "best" in this context. We could merely round all numbers and work with the results:
For example, starting with the work inside parentheses, we have:
5 5/6 - (1 + 4) = 5 5/6 - 5. We must round 5 5/6 up to 6. Then the "best estimate' is 6 - 5, or just 1.

Answer:
2250 watt-hours
Step-by-step explanation:
Okay, so we first need to find out how many watt-hours the light bulb consumes in 1 hours, so we need to divide 600 by 24 hours, which gives us a rate of 25 watt-hours per hour.
So if the light bulb consumes 600 hours per day, and it runs for 3 days, you multiply 600 by 3 to get 1800.
And because we know that it also consumes 25 watt-hours per hour, we multiply 25 and 18 together to get 450 hours.
Finally, you add 1800 and 450 together to get 2250 watt-hours.
Hope this helps :)
75 - 18.5 = 56.5
the number is 56 1/2 or 56.5
Answer:
a right triangle
is equal to
Step-by-step explanation:
Pythagorean's theorem is a²+b²=c² with c being the longest sides. If it is true then it is a right triangle.
<u>18²</u> + <u>24²</u> = <u>30²</u>
324+576=900
This is true so the triangle is a right triangle
