Answer:
Step-by-step explanation:
Basically, you want to know interest. I = prt is the formula. 'I' will be left blank b/c that's unknown. P is principal, 5000. R is rate, 4%, or 0.04 when turned into a decimal. T is time, 7 years. So now when using the formula, it will all become I = 5000(0.04)(7). What that means is you first multiply 5,000 by 0.04, getting 200. Then when you multiply 200 by 7, it's 1,400, which will leave you with I = 1,400. Interest is 1,400.
Answer
b 32
c 50
Step-by-step explanation:
The correct answer to this question is this one: "4/45"
inverse variation ---> wt = constant
let wt=k
<span>put w=4, t= 1/5 and find k
</span>
So the correct answer for k is 4/5
wt = 4* (1/5) = 4/5 = k\
so your function is
wt = 4/5 or t= 4/(5w)
now to get t, when w=9, just put w=9 in t=4/(5w)
So that makes 4/45
