Answer:
222 2/9 hours
Step-by-step explanation:
Income = hours * dollars per hours
We need an income of 2000
We get $9/ hour
Substitute in what we know
2000 = hour * $9
Divide by 9 on each side
2000/9 = hours
222.222(repeating) = hours
222 2/9 hours
If we want to know how many days, we will divide by 5 since she works 5 hours a day
222 2/9 ÷5
44 4/9 days
Answer:
Depends on domain of x, could be
-√(y+10)/7; √(y+10)/7 or no solutions
Step-by-step explanation:
You need to solve it for x:
y=7x^2-10
7x^2=y+10
x^2=(y+10)/7
In order for this equation to have an inverse, you need to check the domain of x. There needs to be only one solution for x^2=(y+10)/7 - either positive or negative, depending on the domain.
Answer:
Step-by-step explanation:
Draw a picture. Seriously, this time you need to, so you can see that PS is the hypotenuse of a right triangle with legs of length 3 and 4 .
PS = √(3² + 4²) = 5
Perimeter = PQ + QR + RS + PS = 9 + 4 + 6 + 5 = 24 cm
Answer:
226.08 square inches
Step-by-step explanation:
Area of a circle is given by

Where r is the radius and r is the area.
For this case, since one half is painted yellow and another red, then the area for each paint will be given by

Substituting 12 inches for r then

Therefore, each paint occupies approximately 226.08 square inches
