Roxanna earns $18 per hour.
If Roxanna earns $72 in 4 hours, then the equation to find how much she earns per hour is:
72/4 = x
x = 18
Hope this helps! Feel free to ask questions.
The tax is found by mult. the total purchase by 1.07:
1.07(3)($0.99) = $3.18 (rounded up to the nearest cent)
given the function, there is no independent variable, x. Because of that your equation remains constant at the y axis, where you get f(x)=57. This means that for any input of x you’ll get 57 as the output. Because youre looking for average rate of change, you would use delta y/ delta x.
(2,57) and (6,57)
When you solve for change between the y and x, you get (57-57)/(6-2
) which ultimately gives you an average rate of change of 0.
Answer:
1200
Step-by-step explanation:
Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute. Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.
(I might get this wrong, so like yeah.)
Well what you do is the square root of 7 Is 49 so if you done 49 divided by 7 it would equal 7 if you squared a number you would times it by itself the square root is the opposite
