If I owe you $1.76 in overtime pay, you receive $19.50 for each hour of OT. How many hours overtime are you owed?

Lady_Fox [76]

Answer: 0.09 hours

Step-by-step explanation:

You are owed $1.76 in overtime pay.

The hourly rate for overtime is $19.50 per hour.

To find the number of hours owed, you need to divide the amount owed by the amount owed per hour.

The number of hours you are owed is therefore:

= Amount owed / Amount owed per hour

= 1.76 / 19.50

= 0.09 hours

What are the zeros of this function? (pictured above) How do you know?

arlik [135]

Answer:

x=-1 and x=3

Step-by-step explanation:

The zeroes of a function are its x-intercepts when the function passes through the x-axis. In this case, the parabola passes through (0,-1) and (0,3) which means the x-intercepts are x=-1 and x=3, which are also the zeroes.

One month ruby worked 8 hours more than Issac,and Shetland worked 4 times as many hours as ruby. Together they worked 136 hours.

Natalka [10]

R=number of hours ruby worked
i=number of hours issac worked
s=number of hours shetland worked

ruby worked 8 more than issac
r=8+i

shetland worked 4 times as many as ruby
s=4r

total they worked 136
r+i+s=136

so

we gots
r=8+i
s=4r

for r=8+i
solve for i
minus 8 both sides
r-8=i

so

r+i+s=136
subsitute r-8 for i and 4r for s
r+r-8+4r=136
6r-8=136
add 8 to both sides
6r=144
divide both sides by 6
r=24

sub back

r-8=i
24-8=i
16=i

s=4r
s=4(24)
s=96

ruby worked 24 hours
issac worked 16 hours
shetland worked 96 hours
