Answer: $95450

Step-by-step explanation:

We obviously want to look in the 3rd column.

Income that can be taxed is within interval for 33%, so (0.33)(315000) = $103950.

Subtract the tax credit, and we get $103950 - $8500 = $95450.

A cup of coffee at 85 degrees Celsius is placed in a room at 25 degrees Celsius. Suppose that the coffee cools at a rate of 5 de

Answer: k = - 6.6667

Step-by-step explanation:

this is quite very simple to begin. I would encourage you take other practice questions similar to help with understanding it.

let us begin.

Given that ;

dT/dt = k ( Tm - T) where Tm is the temp of the medium

dT/dt = 5 degrees Celsius per minute when T = 70

so we have that, 5 = k ( 25 - 70)

remember to convert 5 degree celsius per minute to seconds

we have that;

5*60(sec) = k ( 25 - 70)

k = 5*60 / ( 25 - 70)

k = - 6.6667

note K is negative because we consider it for cooling process (temp decreasing).

cheers i hope this helps!!!

Cost of painting is GHe 109,320

Given:

Floor measure = 15 m by 8 m

Cost of carpeting = GHe 890 per square meter

Total cost of painting and carpeting = GHe 216,120

Find:

Cost of painting

Computation:

Area of floor = 15 × 8

Area of floor = 120 square meter

Cost of carpeting = 120 × 890

Cost of carpeting = GHe 106,800

Cost of painting = Total cost of painting and carpeting - Cost of carpeting

Cost of painting = 216,120 - 106,800

Cost of painting = GHe 109,320
