In Triangle ABD using Pythagoras theorem we can write

AB^2=AD^2+BD^2\\ \\ AB^2=9^2+BD^2\\ \\ AB^2=81+BD^2\\

Now In Triangle BCD Using Pythagoras theorem we get

BC^2=BD^2+CD^2\\ \\ z^2=7^2+BD^2\\ \\ z^2=49+BD^2\\

Now in larger Triangle ABC using Pythagoras theorem we can write

AB^2+BC^2=AC^2\\

Now substitute the values from above two equations we get

AB^2+z^2=(9+7)^2\\ \\ 81+BD^2+z^2=16^2\\ \\ BD^2=z^2-49\\ \\ 81+z^2-49+z^2=256\\ \\ 2z^2=224\\ \\ z^2=112\\ \\ z=4\sqrt{7}

Which equation can be used to find the number of fish in the pond on June 1?
olga_2 [115]

Answer: The required equation is f-52=63 and the number of fishes in the pond on June 1 = 115


Step-by-step explanation:

Given: The number of fishes in pond on July 1 = 63

Also, it is said that the number of fishes in pond on July 1 is 52 fewer(lesser) than the number of fishes in pond on June 1.

Let f be the number of fishes in pounds on June 1.

then the required equation will be

f-52=63

Now, add 52 on both the sides  of the equation, we get

f=63+52\\\Rightarrow\ f=115

Someone pls help me plsss
Lelu [443]

Answer:

A) 2 5/12

Step-by-step explanation:

The word <u>MORE </u>refers to subtraction. If you know how to calculate fractions. Great! You should know what 2 3/4 - 1/3 equals. But if you do not:

You can use a regular calculator. Just convert everything to decimals. ( "/" means divide)

3/4 (3÷4) = 0.75 (dont forget the 2 since is has 2 3/4) so 2.75.

1/3 (1÷3) = 0.33<u>3 </u>(underline or overline (above the number) means that number repeats. if you are using a calculator. just max the numbers out till you can put it anymore.

2.75 - 0.<u>3</u> = 2.41<u>6</u>. Now you dont know what that 416 is so just subtract the answers until it matches.

B) 1 ÷ 12 = 0.8<u>3. </u> well it isnt 416 so that isnt right.

4 ÷ 7 = 0.571... (... means a bunch of numbers that go on and on.) again that isnt correct. Now lets try A):

5 ÷ 12 = 0.41<u>6</u>!

Hope this helps!
