Answer:
two ways
Step-by-step explanation:
there are two ways to do this
640/4 =160
take 160x16 = 2,560
OR
640x4 = 2,560
4 because 4x4 = 16
Inverse variation is of the form y=k/x (direct variation is of the form y=kx)
We are given that x=2 when y=1 so using the inverse form y=k/x we can solve for the constant of variation...
1=k/2
k=2
so the equation is:
y=2/x now they want us to find y when x=-1 so
y=2/-1
y=-2
Answer:
25 cm
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 24^2 = c^2
49 + 576 = c^2
c^2 = 625
c = 25
Answer: 25 cm
The deposit is 4,000 so P = 4000.
The interest rate is 9.5%
9.5 ÷ 100 = 0.095.
r = 0.095: I = P*r*t*: I = P*r*tl = 4000*0.095*
(270/365)I = 281.095890410959 I = 281.10
So your answer would be: 281.10
First markdown: 0.75($500) = $375
Second markdown: 0.75($375) = $281.25
Third markdown: 0.75($281.25) = $210.94
