25% 6 divided by 24 will give you the percentage of copper in the bar
Answer:
540 ft^2.
Step-by-step explanation:
The area of the trapezoid = h/2 (10 + 18) = 14h.
By Pythagoras the height h = √(5^2 - 4^2) = 3.
So the area of the 2 trapezoidal bases = 2 * 14*3
= 84 ft^2.
Now we calculate the area of the four lateral rectangular sides:
= 10*12 + 18*12 + 2*5*12
= 456 ft^2.
Total area = 456 + 54
= 540 ft^2.
Answer:
282 hr <======= see below
Step-by-step explanation:
Distance / rate = time
2.4 x 10^9 mi / 85 m/hr = 28235294 hr
You must have left the power of 10 off of your speed
probably should be 8.5 x 10^6 perhaps? then answer is 282
<h3>If speed was 8.5 x 10^5
then answer becomes ~ 2820 </h3>
Lab Safety is the main starting point on the scientific process.
