Answer:
a = 7
Step-by-step explanation:
The Pythagorean theorem tells you the value of 'a' is ...
a^2 = b^2 - c^2
a^2 = 25^2 -24^2 = 625 -576 = 49
a = √49 = 7
The length of side 'a' is 7 units.
Answer:
L = 0.02d + 10
Step-by-step explanation:
The hair starts at 10 inches long.
L = 10
Now we add 0.02 inches in length per day.
In 1 day, it grows 0.02 inches.
In 2 days, it grows 0.02 * 2 inches.
In d days, it grows 0.02d inches.
Now we add the starting length, 10, and the growth per day, 0.02d, to get:
L = 0.02d + 10
Answer:
the answer would be 0 because 0+5=5
<span>The question is asking us to multiply three numbers and then to round the result to the nearest hundredth. First we will calculate: 7.2 * 12 * 0.23 = 19.872. Now we have to round it to 2 decimal places. If we had 19.875 as a result we would round it to 19.88. But we have 19.872 ( 2 is smaller than 5 ) and we will round it to 19.87. Answer: C ) 19.87. </span>
21.12 is 25.6% of 82.5. I hope this helps. :)
