The answer is B estimated number is 20
Answer:
correct option is C) 2.8
Step-by-step explanation:
given data
string vibrates form = 8 loops
in water loop formed = 10 loops
solution
we consider mass of stone = m
string length = l
frequency of tuning = f
volume = v
density of stone = 
case (1)
when 8 loop form with 2 adjacent node is 
so here
..............1
and we know velocity is express as
velocity = frequency × wavelength .....................2
= f × 
here tension = mg
so
= f × ..........................3
and
case (2)
when 8 loop form with 2 adjacent node is
..............4
when block is immersed
equilibrium eq will be
Tenion + force of buoyancy = mg
T + v × × g = mg
and
T = v × - v × × g
from equation 2
f × 
= f × 
.......................5
now we divide eq 5 by the eq 3
solve irt we get
so
relative density 
relative density = 2.78 ≈ 2.8
so correct option is C) 2.8
Answer:
Domain: All real numbers greater than or equal to 1.
Step-by-step explanation:
Answer 1: -14 is not in the domain
Answer 2: 4 is included in the domain
The equation that represents the situation will be (0.75x) + 0.8(x + 10) = 101
<h3>How to compute the equation?</h3>
From the information, Jared attempted x shots and made 75% of them. Zach attempted 10 more shots than Jared did and made 80% of them.
Therefore the equation that represents the situation will be:
= (0.75 × x) + 0.8(x + 10) = 101
= 0.75x + 0.8(x + 10) = 101.
Therefore, the equation that represents the situation will be (0.75x) + 0.8(x + 10) = 101

Start with the distance equation D=RT, then plug in numbers
194=R x 4.2, so all we have to do is divide 194 by 4.2.
