A dolphin ate 2604 pounds of fish during the 31 days in march. What is the average amount of fish the dolphin ate per day.
Ivanshal [37]

To find the average of something you add up all of the data points (in this case it would be how many pounds offish were eaten per day but this is already done for us) then you would divide by the number of points you have (the number of days which is 31). So all you have to do is 2604/31. This equals 84 pounds of fish per day on average.

Help is needed please help
Anna007 [38]

You have to do Pythagorean theorem:

a^{2} +b^{2}  = c^{2}

"a" and "b" are the legs. In this case 7 is a leg and x is a leg

"c" is the hypotenuses, which is 19 here

so...

a = 7

b = x

c = 19

Plug the numbers above into the equation:

7^{2} + x^{2} = 19^{2}

49 +x^{2} = 361

Isolate x by subtracting 49 to both sides:

(49-49) + x^{2} = 361 - 49

x^{2} = 312

To solve for x you have to take the square root to both sides of the equation:

\sqrt{x^{2} } = \sqrt{312}

x = 17.6635

x = 17.7

Hope this helped!

Solve for angle A with sides 6,10,9
OLga [1]

Answer:

c = 13.52 units.

Step-by-step explanation:

So for this, lets use the Law of Sines, which says that:

Sin A / a = Sin B / b = Sin C / c

We have everything for this except the the angle measure of angle C. This can be found by doing 180 - 80 - 33, since the total interior angle measure of a triangle always equals 180 degrees.

180 - 80 - 33 = 67 degrees

With this, we can use the angle & side of A/a as well as the angle of C to get the side of c by using the Law of Sines

Sin A / a = Sin C / c

sin 33/8 = sin 67/c

c = 8*sin67 / sin 33

c = 13.52 units.

4/4 plus 4/4 please help
krek1111 [17]
Simplifying is basically 1 + 1, so the answer is 2, or 8/4 whichever you prefer. 
It can also be 4/2, or 2/1...
