Answer:
5/9
Step-by-step explanation:
Let the total number of buttons is x.
- Round buttons = 80% of x = 0.8x
- Square buttons = 0.2x
<u>Number of red buttons:</u>
- 0.1*0.8x + 0.5*0.2x =
- 0.08x + 0.1x =
- 0.18x
Number of red square buttons is 0.1x
<u>Required probability:</u>
- P = 0.1x/0.18x = 10/18 = 5/9
Take 9 from 6 = -3
Take 10 from 9 = -1
Take 50 from 40 and leave 6 = -4
Answer:
$123.48 per week
Step-by-step explanation:
$ = (13.72)(9)
Multiply:
$123.48
Step-by-step explanation:
step 1. The segment x is made up of 2 equal lines which are connected in the middle to another segment 12 units long.
step 2. the intersection of these two segments must create a 90° angle because the two lines are equal.
step 3. The lower segments are identical to the upper segments.
step 4. therefore x = 11(2) = 22.
