Answer: Hi, first lets give our variables some names.
Lets call Ks to Karen's salary and Js to Jason's salary.
then, in 1995:
Ks₁ - Js₁ = 2000$
in 1998:
Ks₂ - Js₂ = 2440$
now, we know that Ks₂ = (1 +p)*Ks₁ and Js₂ = (1+p)*Js₁
so we can write the second equation as:
p*(Ks₁ - Js₁ ) = 2440$
replacing the parentesis with the first equiation
(1+p)*(2000$) = 2440$
(1+p)= 2440/2000 = 1.22
so p = 0.22, or a 22%
Your answer is 6 times 6 =36 and 9+1=10 , 8+2=10, and so on
Answer:
72
Step-by-step explanation:

Answer:
2/9
Step-by-step explanation:
28 marbles in all
"Half of the marbles are red."
28/2 = 14 red
"Half of the non-red marbles are white..."
14/2 = 7 white
"...and the rest are blue."
25 -14 -7 = 7 blue
"Todd chose a <u>white marble</u> at random... " -from the bag that has...
14 red 7 white 7 blue
"... and <u>kept it</u>."- so now the marbles left in the jar are...
14 red 6 white 7 blue
P (white) = Number of white marbles/ Total number of marbles = 6/27 = 2/9
Step-by-step explanation:
x² = 25/784
Since 25 = 5² and 784 = 28²,
x = ±(5²/28²) = ±5/28.
