Answer:

5√7

Step-by-step explanation:

c is the hypotenuse NOT the leg (I just took a quiz and had the exact same question). Therefore:

16^2 - 9^2  = a^2

256 - 81 = a^2

175 = a^2

a^2 = 5√7

If c is the hypotenuse and b is the leg, then the third side (a):
a= \sqrt{c^2-b^2}= \sqrt{16^2-9^2}= \sqrt{256-81}= \sqrt{175}=5 \sqrt{7}

If b and с are legs, then hypotenuse (a):
a= \sqrt{b^2+c^2}= \sqrt{9^2+16^2}= \sqrt{81+256}= \sqrt{337}

Answer:

-9 + 21 = t t = 12°C.

Step-by-step explanation:

For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees  it will give us our original degrees. Solve. -9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12) 12 = t So, the original degrees in the beginning of the day was 12°C.

what is the answer to the multiplication problem. Jhon has 20 fish if he lets 6 fish go how many fish dose Jhon have?
spayn [35]
Isn't this a subtraction problem, not a multiplication problem?

If John starts out with 20 fish and lets 6 go, he still has (20-6), or 14, fish.
