Answer:
1 : 10
Step-by-step explanation:
Let :
Water = x
Milk = y
Purchase = 6.4 * y = 6.4y
Sales = 8(x + y)
Profit accrued = 37.5%
Sales = profit made from sales
8(x + y) = 6.4x * (100%+37.5%)
8(x + y) = 6.4x * 1.375
8x + 8y = 8.8x
8y = 8.8x - 8x
8y = 0.8x
y/x = 8/0.8
y/x = 10 / 1
y : x = 10 : 1

Justin wanted to walk 3.5 miles a day for a whole year if he meets his goal of walking 3.5 miles a day for the entire year, how total miles will Justin walk in a year?
Answer:
1277.5
Step-by-step explanation:
365 days in a year. If he walks daily 3.5 miles, then 3.5*365
3.5*365= 1277.5

what are the value of x in the equation x^2+4-1 =0
Answer:
x = ±sqrt(3) i
Step-by-step explanation:
x^2+4-1 =0
Combine like terms
x^2 +3 = 0
Subtract 3 from each side
x^2 +3-3 = 0-3
x^2 = -3
Take the square root of each side
sqrt(x^2) = sqrt(-3)
x = ±sqrt(3) sqrt(-1)
x = ±sqrt(3) i
1. Samuel is out with a kite. When he takes a break he attaches it to the floor. The kite is on a thread that is 16 meters long and makes a 30 degrees angle with the floor. How high above the floor is the kite?
Answer:
[tex]h=8m[/tex]
Step-by-step explanation:
From the question we are told that:
Slant height [tex]S=16meters[/tex]
Angle [tex]\theta =30[/tex]
Generally the equation for Height h is mathematically given by
[tex]h=Ssin\theta[/tex]
[tex]h=16*sin30[/tex]
[tex]h=8m[/tex]
y+1=3(x – 4)
2-intercept:
C
y-intercept:
Answer:
x-intercept is (13/3, 0)
y-intercept is (0,-13)
Step-by-step explanation:
change y+1 = 3(x-4) into slope-intercept form:
y+1 = 3x-12
y = 3x-13
y-intercept is (0,-13)
to get x-intercept, plug zero in for 'y' and solve for 'x':
0 = 3x-13
13 = 3x
13/3 = x
x-intercept is (13/3, 0)

The graph shows two lines, A and B, that Harry graphed.
Part A: How many solutions to the pair of equations for lines A and B does Harry find? Explain how he knows this.
Part B: Write the solution to Harry's equations of line A and B in (x, y) format? Explain to Harry how you know this is the solution for both equations. This is NOT the same as the explanation in Part A.
Answer:
We see two intersecting lines.
It means there is one solution, it is the intersection point.
Solution is (3, 4)
It was easy to find the solution as both lines and their intersection is visible on the graph.
With two parallel lines we would have no solutions and with overlapping lines we would have infinitely many solutions.
If you only have the equations of the lines you need to compare the slopes, if they are different it means lines are intersecting at one point hence one solution.
With same slopes and different y-intercepts there is no solution.
With same slopes and y-intercepts there is infinitely many solutions.

Answer:

Step-by-step explanation:
Determine wether the lines are parallel perpendicular or neither
Answer:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
