Tommy works two jobs. As a clerk he earns
$7 an hour. As a receptionist he makes $9 an
hour. One week he worked 24 hours and
earned $200. How many hours did he work
at each job that week?

Clerk: 8 hours

Receptionist: 16 hours

Step-by-step explanation:

Hours as a clerk: x

Hours as a receptionist: y

x + y = 24

x = 24 - y

7x + 9y = 200

7(24 - y) + 9y = 200

168 - 7y + 9y = 200

2y = 32

y = 16

x = 24 - 16 = 8

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
