He has 2 jobs paying different rates.
At $15/hr for 8 hours, he earns $120.
At $18/hr for 4 hours, he earns $72.
Summing these up: $120 + $72 = $192
Dividing by the total # of hours worked (12),
$192
--------- = $16/hr (average rate)
12 hr
Infinite they’re all multiples, so they are the same line
Slopes of perpendicular segments are always negative reciprocal of each other. Or, we can say product of slopes of perpendicular segments is always -1.
Given the slope of PQ is 5/2.
So the slope of its perpendicular segment should be -2/5.
Finding slopes of given options:-
From above calculations, it is clearly visible that slopes of RS and VW are negative reciprocal of slope of PQ.
So, correct answers are RS and VW.
A 4/52 7.69%
b 1/52 1.92%
c 2/52 3.84%
d 13/52 25.00%
e 39/52 75.00%.
f 16/52 30.76%
g 3/52 <span>5.76%.</span>

The minimum number of T-shirt that they must sell to raise $500 is 67 T-shirts
Let x represent the number of Pi Day T-shirts sold.
They are selling Pi Day T-shirts for $7.50 each, So to raise $500:
7.5x > 500
Dividing through by 7.5:
7.5x / 7.5 > 500 / 7.5
x > 66.7
Hence, the minimum number of T-shirt that they must sell to raise $500 is 67 T-shirts
