Answer:
Jesicaa=$59
Ashley=$71
Devyn=$98
Step-by-step explanation:
Let Jessica's earning be x:
-Given that the total earnings for the three was$228. earnings per person is calculated as:
#Equate their earnings to the 228 to solve for x:
#Substitute for x in each earning equation to determine individual earnings:
Answer:
The answer is B.
Step-by-step explanation:
I converted everything into decimals and went from there.
Let's look at the picture, let's imagine that the gray line is the perimeter fence and that the red OR the blue is the one dividing it. We can see that the blue line is longer than the red one, so it will be advantageous, to have a bigger area, to have the dividing fence the smallest possible.
Let's say then that the width (W) is bigger (or equal) to the length (L), so we have:
The area is W*L, so we have
this function is a parabola facing down, its zeros are 0 and 80, therefore its maximum is when L=40
hence, L=40 and W=(240-120)/2=60
It will be a rectangle, measuring 60x40 and the divinding fence will be 40
Okay I dislike improper fractions but the way to do this
see how many times the bottom number (denominator) goes into the top number (numerator)
4 can go into 15 3 times so 3 is your whole number
now you have 15-12=3 and that last three will be your next numerator
so your answer will be
3 3/4
