Hopefully try is works. Took me a few hrs to figure it out but I think I got it
Answer:
x + y = 60 and 1.55x + 1.4y = 88.20 and the solution is x = 32 and y = 28.
Mr. Sanchez’s class earned more money by $10.4.
Step-by-step explanation:
Mr. Sanchez’s class sold fruit pies for $1.55 each and Mr. Kelly’s class sold bottles of fruit juice for $1.40 each.
Let the number of sold fruit pies is x and bottles of fruit juice is y.
So, from the given condition we can write
x + y = 60 ........ (1)
⇒ 1.4x + 1.4y = 84 ....... (2) and
1.55x + 1.4y = 88.20 ........ (3)
Now, solving equations (2) and (3) we get (1.55 - 1.4)y = (88.2 - 84)
⇒ y = 28
And from equation (1) we get x = 60 - 28 = 32.
Therefore, Mr. Sanchez’s class earned more money. (Answer)
Now, this class have earned $(32 × 1.55 - 28 × 1.4) = $10.4 more. (Answer)
Answer: y = 4x/3 - 5/2
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
c represents the y intercept
m = slope = (y2 - y1)/(x2 - x1)
The given line, L1 passes through A(6, - 7) and B(- 6, 2). The slope of line L1 is
m = (2 - - 7)/(- 6 - 6) = 9/ -12 = - 3/4
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.
Therefore, the slope of line L2 passing through the midpoint, M is 4/3
The formula determining the midpoint of a line is expressed as
[(x1 + x2)/2 , (y1 + y2)/2]
Midpoint, M = [(6 + -6)/2 , (- 7 + 2)/2]
= (0, - 5/2]
This means that the y intercept of line L2 is - 5/2
The equation of L2 becomes
y = 4x/3 - 5/2
Answer:
On first visit, weight =550 g
Weight gained on second visit= 350 g
Weight gained on third visit= 300 g
Present weight=550+350+300= 1200
Weight gained=1200-550=650
Percentage of weight increased
-------->650/550 × 100 = 118.18\%
So the kitten gained 118% weigh
