Answer:
36
Step-by-step explanation:
Okay! This question is a very simple one, but without a calculator, your answer could easily vary from others! So, let´s do this one together!
The equation:
0.810x0.00048/0.000400x0.027
Let´s do the top :
0.810 x 0.00048 = 0.0003888
I will leave these numbers the same until the last part, lets not round them.
Bottom:
0.0004 x 0.027 = 0.0000108
And again I am not going to round this number.
Now we can divide!
0.0003888/0.0000108 = 36
I hope this helped!
Answer:
2 weeks
Step-by-step explanation:
Given in the question that,
Equation that represent Lisa's total amount of money
f(x) = 20 - 13x
Equation that represent Joey's total amount of money
g(x) = x² - 10
To find weeks, x, after which they will have same amount of money, we will equate both equation
<h3>20 - 13x = x² - 10</h3>
x² - 10 - 20 + 13x = 0
x² - 30 + 13x = 0
x² + 13x - 30 = 0
(x - 2)(x + 15) = 0
x = 2 or x = -15
Weeks, x, can not be negative so we will reject x = -15
Hence, after 2nd week Lisa and Joey will have the same amount of money save.
