Answer:2 7/12 hours.

Step-by-step explanation: First, convert 1 3/4 to improper fraction form which will give you 7/4. Then find the common denominator of 5/6 and 3/4. The common denominator is 24. 5/6=20/24. 7/4=42/24. 20/24+42/24= 2 7/12.

Answer:

330cm

Step-by-step explanation:

The formula to find the surface area of a rectangular prism is 2(lh+hw+lw)

(lh) in this formula is length times height

(hw) is height times width

(lw) is length times width

To find the answer to this problem lets make the height 3/5cm the width 10cm and the length 15cm

so now you would do (15*3/5) which is 9. This solve (lh)

then you would find (3/5*10) which is 6. This solves (hw)

and lastly you would find (15*10) which is 150. This solves (lw)

Now that you now the value of each one of these you replace it in the equation as so: 2(9+6+150)

now you solve the brackets which leaves us with 2(165)

now you multiply 2 with 165

and the answer is 330cm

Surface area = 330cm

An appliance company uses the function f(h) = 40h + 120 to calculate the total repair bill, f(h), for h number of hours worked.
Verdich [7]

Answer:

fh. = 40h + 120,  fh. = $200

200 = 40h + 120

200 - 120 = 40h

80 = 40h

80/40  = h

 2 = h

h = 2 hours.
