Answer:
Length of QR = 7
Step-by-step explanation:
20 - 13 = 7
<u>Answer</u>
3.5 hours.
<u>Explanation</u>
The first step is to calculate the constant of proportionality.
t ∝ 1/n
t = k/n Where t = time, K= constant and n = number of people
t = k/n
k =tn
= 5×7 = 35
The equation becomes;
t = 35/n
for n = 10,
t = 35/10
t = 3.5 hours.

Answer:
see below
Step-by-step explanation:
The area of a square is the square of the side length, as shown in the given table.
The area of a circle is pi (π) times the square of the radius. For a radius that is the same as the side length of a square, the circle will have an area π times as large.
For an input of 3, the square area function outputs 9.
For an input of 3, the circle area function outputs 9π, about 28.3.
Step-by-step explanation:
let gold fish= X
let Plecos fish= Y
X +Y = 17................(I)
13.49X + 3.25Y =198.61........(II)
solve simuteniously to get
X = 14
Y = 3.....therefore
she bought 14 gold fish and 3 plecos fish
