13 out of the 213 tagged returned
13/213 is estimate of how many fraction returned
proportional, marked/totalmarked≈caught/totalinlake
213/13=total/104
times both sides by 104*13 (cross multiply)
213*104=total times 13
22152=total times 13
divide both sides by 13
about 1704 bass in the lake

Answer: (C) divide by 1

<u>Step-by-step explanation:</u>

when dividing by x - 1, set the expression equal to zero to find the zero.  That is actually what you are dividing by:

x - 1 = 0   ⇒   x = 1

so the number outside of the synthetic division symbol is 1.

Can someone help me with this problem please? Thank you!
Olenka [21]

Answer:

50

Step-by-step explanation:

since the Pythagorean theorem is

c= √a^2+b^2

b is the bottom line (48)

a is the right line (14)

c is the top line (c)

plug that in

c = √14^2 + 48^2

then do the exponets

14^2 = 14 * 14 = 196

48^2 = 48 * 48 = 2304

then add them together

196 + 2304 = 2500

c = √2500

the sqrt of 2500 is 50 (50 * 50 = 2500)

c = 50

your answer is 50

hope this helps:)
