Ok, so if janelle earns 16 dollars for 2 hours, then this means that she earns 8 dollars for 1 hour.
So now you will divide 40 by 8 to get 5 hours

The next model of a sports car will cost 4.4% more that the current model. The current model costs $48,000, How much will the pr
podryga [215]

Answer:

$50,112.  Increase is $2,112

Step-by-step explanation:

1st way.  $48,000 x 1.044 = $50,112.  1.044 is the same thing as saying 104.4% of the total price in decimal form, which is what the new price would be when adding 4.4% to the 100% of the original price.  To get the amount of increase just find the difference in the two.  $50,112-$48,000 = $2,112

2nd way.  $48,000 x .044.  =  $2,112 .044 is 4.4% in decimal form. So you found the increase here.  Add the increase to the original price.  $48,000 + $2,112 to get the new price of $50,112.

Is a triangle with the given side lengths of 15cm, 17cm, and 19cm a right triangle?
Alexandra [31]
Lets see!
We need to use the pythagorean theorem (a^2+b^2=c^2) to check.
So..
15^2+ 17^2 = 19^2
225+ 289= 361
Hm 225 and 289 do NOT equal 361 therefore it is NOT a right triangle.
