Answer:
-3 4/9
Step-by-step explanation:
The fractions all have the same denominator, so are easily added.
Of course, you know how to add signed integers.
4/9 - 3/9 - 5/9 + 5 - 8
= (4 -3 -5)/9 +(5 -8)
= -4/9 -3
= -(3 4/9)
So it must have side length √16 = 4 cm and diagonal length 4√2 cm.
Answer:
y = 3/2x
Step-by-step explanation:
it seems what they are asking for here is our slope.
To find this, we must figure out the change in y over the change in x.
This can be viewed as:
Δy/Δx = slope
In this case, we can see that the line crosses at (4,6), and at (0,0)
Since our y changes by 6, and our x changes by 4, our slope is:
6/4 = slope
Or:
3/2 = slope
So your answer is 3/2x.
Hope this helps!
Answer:
a) 198.7% interest
Not too sure about answer to (b)
b) 4.75% annualized
Step-by-step explanation:
a) i used Interest = Principal x Rate x Time
40 = 525 x 
x r
40 = 20.13r
r = 1.987 or 198.7%
b) i used this proportion: 
= 
'x' represents annualized rate
1/24 represents 2 weeks out of a year
1/24x = 1.98
x = 4.75%
