Shall we make life simpler by eliminating unnecessary numbers.
<span>Totally, my expenses would be 60+200 = $260. Let us say that of this $100 would be met by the weekly bonus so that the residual part of the requirement is $160. </span>
<span>Let x be the number of hours I work. Then my earning would be 11x. For break even, earning should equal requirement. That is 11x = 160. And so, x = 160/11 = 14.55 hours/week </span>
Answer:
6
Step-by-step explanation:
Since you're familiar with your multiplication tables, you know that ...
42 = 6 × 7
There are 6 tiles in each of the 7 rows.
For a 45-45-90 triangle if the sides rae x then the the hytponuse is x√2
(x is the missing side)
5. 10=x√2
10/√2=x
rationalize denom, times top and bottom by √2
10√2/2=x
5√2=x=XY
6. 12√2=YZ
7.
7√2=XZ
8.
7*2=14=XZ
for 30-60-90
the side oposite the 30 deg is x
side oposite 60 is x√3
side oposite right angle is 2x
hyptonuse is oposite right angle
20=2x
10=x=shorter leg
shorter leg is 10 units
the hyptonuse
Given:
60% of what he earns is for spending.
40% of what he earns is for savings.
n = earnings
r = savings
r = n(100-60%)
r = 109 (40%) = 43.60
r = 200 (40%) = 80.00
r = 400 (40%) = 160.00
r = 500 (40%) = 200.00
n r
109 43.60
200 80.00
400 160.00
500 200.00
