Let x = hours worked as a clerk ($12 per hour).
Let y = hours worked as a cashier ($8.25 per hour).
She worked 55 hours, therefore
x + y = 55 (1)
She earned $585, therefore
12x + 8.25y = 585 (2)
From (1), obtain
y = 55 - x (3)
Substitute (3) into (2).
12x + 8.25(55 - x) = 585
12x + 453.75 - 8.25x = 585
3.75x = 131.25
x = 35
y = 55 - x = 55 - 35 = 20
Answer: a) Office clerk: 35 hours; cashier: 20 hours.
How many seconds are in a minute?
We need to multipy the number of ft falling per second by 60 to get fpm.
60 x 176 = 10,560 fpm
Answer:
8 dollar/hr
Step-by-step explanation:
she worked 2 1/2 hrs yesterday and 4 1/4 hrs today
2 1/2 + 4/14
2+4 is 6
and 1/2+1/4 multiply 2 to both numerator and denominator of 1/2 so that the denominator of both fraction is like
it will now become 2/4+1/4 which equals 3/4
This means that she worked total of 6 3/4 hour in all yesterday and today
she is paid 54 dollar
we will need to divide 6 3/4 or written as 6.75 by 54 to find how much she earns per hour
and that would be 8
so she earns 8 dollar per hour.
To find a,construct a line that parallel to AB and DE cutting c, which you could refer to the photo((sorry for my terrible diagram ^^;;
from the photo,we can see that
a= <BCG + <GCE
<BCG=44° (alt.<, AB//FG)
<GCE=20° (alt<, FG//DE)
thus,a= 44°+20° =64°
hope it helps!
