write the equation of a line parallel to the line with the equation
a. 3x- 6y=12 b. 5x-y=10
Answer:
[tex]y=\frac{1}{2}x+6[/tex] and [tex]y=5x+8[/tex]
Step-by-step explanation:
The big thing to remember with this is that parallel lines have the same slopes. We can isolate the y-variable in both of these to get the slope-intercept form, which just makes it easier to see the slope.
a. 3x-6y=12
[tex]-6y=-3x+12\\y=\frac{1}{2}x-2\\[/tex]
Now that we know the slope, we can have any y-intercept except for the original one, they just need to have the same slope. So an equation that could work is [tex]y=\frac{1}{2}x+6[/tex].
b. 5x-y=10
This equation can be solved in the exact same way.
[tex]-y=-5x+10\\y=5x-10[/tex]
Parallel line: [tex]y=5x+8[/tex]
Again, it does not matter what the y-intercept is, they just can't have the same one. The slopes have to be the same.
Hope this helps!

The European Working Time Directive (EWTD) directs that staff should work no more than an average of 48 hours a week, over a 13-week period. You work from 9:00 - 18:45 with a 30 minutes lunch break for three days a week and from 10:30 - 21:00 two days a week with a 45 minutes break. You also work from 10:00 – 14:00 every second Sunday. Are your hours EWTD compliant?
Answer:
it is not EWTD compliant
Step-by-step explanation:
Given that :
Directive = maximum average working hours per week = 48 hours
Engagement :
9:00 - 18:45 = (9 hrs 45 mins) - 30 mins = 9hrs 15 mins
9 hrs 15 mins for 3 days = 27 hours 45 mins
10:30 - 21:00 = (10 hrs 30 mins) - 45 mins = 9 hrs 45 minutes
Sundays (10:00 - 14:00) = 4 hours
Total work hours per week :
2(9hrs 15 mins) + 3(9hrs 45 mins) + 4 hours =;
18 hrs 30 mins + 29 hrs 15 minutes + 4 hours
(18 + 29 + 4) + 45 minutes
51 hours 45 minutes.
51 hours 45 minutes > 48 hours ; a Hence, it is not EWTD compliant
A Ferris wheel at an amusement park is modeled by (x – 70)2 + (y – 77)2 = 5,184, where the measurements are in feet. A slingshot attraction is modeled by y = –4x2 + 40x + 50. Which attraction reaches a greater height, and what does it represent in terms of the context?
A. The slingshot reaches a greater height at 50 feet, which is the vertex of the parabola.
B. The Ferris wheel reaches a greater height at 184 feet, which is the highest point on the circle.
C. The Ferris wheel reaches a greater height at 149 feet, which is the highest point on the circle.
D. The slingshot reaches a greater height at 150 feet, which is the vertex of the parabola.
Answer:
D. The slingshot reaches a greater height at 150 feet, which is the vertex of the parabola.
Step-by-step explanation:
First let's examine the given equations
[tex]\displaystyle \rm\\(x -70)^2 + (y-77)^2 = 5184 ............. (1)\\y = -4x^2 + 40x + 50 ............... (2)[/tex]
Equation (1) is of the form of a standard equation for a circle
[tex]\displaystyle \rm (x-a)^2 + y-b)^2 = r^2\\\\[/tex]
where (a, b) is the center of the circle and r is the radius
Equation (2) is the standard equation of a parabola
y = ax² + bx + c where a, b and c are constant
So we know that the Ferris wheel motion is circular while the slingshot motion is parabolic
Let's compute the highest point at which the Ferris wheel reaches.
Given,
[tex]\displaystyle (x-70)^2 + (y-77)^2 = 5184[/tex]
We can see that r² = 5182 by comparing it to the circle equation[tex]\displaystyle x_v=-\dfrac{40}{2\left(-4\right)}[/tex]
Therefore r = √5184 = 72. The diameter = 144 which is the highest point vertically from the center of the circle
The highest point on the circle = 144 + 5= 149 m since there is a 5' gap between the Ferris wheel and the ground at the lowest point so that has to be taken into account
For the parabola the vertex is the highest point and its x-coordinate given by [tex]\displaystyle \dfrac{-b}{2a}[/tex] in the standard equation for a parabola
Comparing the given equation with the standard equation we see that a = -4, b = 40 and c= 50
Therefore [tex]x_v[/tex] the x-coordinate of the vertex:
[tex]\displaystyle x_v=-\dfrac{40}{2\left(-4\right)} = 5[/tex]
The y coordinate of the vertex can be found by plugging in this value into the parabolic equation
[tex]\displaystyle y_v=-4\cdot \:5^2+40\cdot \:5+50 = 150[/tex]
This being the vertical coordinate of vertex of the parabola, the highest point that the slingshot reaches is 150'
So correct answer is D

Answer:
A
Step-by-step explanation:
Lian's work is shown below. Steps Lian's Work Step 1 s + 40 = 68 Step 2 s + 40 minus 40 = 68 minus 40 Step 3 s = 28 In which step, if any, did Lian first make a mistake in her work? step 1 step 2 step 3 no mistake
Answer:
No mistakeStep-by-step explanation:
Given the equation solved by Lian expressed as;
s + 40 = 68
Lian is to find the value of s from the equation, to do that you will follow the steps below;
Step 1: Substract 40 from both sides of the equation;
s + 40 - 40 = 68 - 40
Step 2: Solve for s;
s + 40 - 40 = 68 - 40
s + 0 = 68 - 40
s = 28
Based on the calculation, we can say that Lian made no mistake when solving
Answer:
D, no mistake.

1.Find the compound interest on Rs25000 for 3 years at 10% per annum ,Compounded annually.
Plzz answer this question in step by step explanation.
Answer:
The compound interest is Rs8275
Step-by-step explanation:
The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where
A is the new amountP is the initial amountr is the interest rate in decimaln is the number of periodst is the timeThe interest I = A - P
∵ The amount of investment is Rs25000 for 3 years
∴ P = 25000
∴ t = 3
∵ The rate of interest is 10% per annum, compounded annually
∴ r = 10% = 10 ÷ 100 = 0.1
∴ n = 1 ⇒ compounded annually
→ Substitute these value in the 1st rule above to find the new amount
∵ A = 25000[tex](1+\frac{0.1}{1})^{1(3)}[/tex]
∴ A = 25000[tex](1.1)^{3}[/tex]
∴ A = Rs33275
→ Use the 2nd rule above to find the interest
∵ I = 33275 - 25000
∴ I = 8275
∴ The compound interest is Rs8275

The scale of a map is 3 ft = 84
miles
Map: 4.5 ft
Actual miles:
The actual miles calculated for the given scale of a map is 126 miles.
What is referred as the unitary method?It is a technique that determines the value of a single unit through subtracting the significance of multiple units from the value of a single unit.
The unitary method provides the value of many items, and we must either figure out the amount of more or lesser items.To do so, we must first figure out the worth of one item by division and afterwards multiply the value of more and fewer items.Now, the given question;
The scale of a map is 3 ft = 84 miles
Using unitary method for solving this.
Convert the value for 1 foot.
1 foot = 84/3 miles = 28 miles.
Now, calculate the value for the map of 4.5 ft.
4.5 feet = 28×4.5 miles
4.5 feet = 126 miles
Therefore, the value for map of 4.5 feet is estimated as 126 miles.

please help me out!! it’s either option 1, option 2, option 3, or option 4
Answer:
It's option 2
Step-by-step explanation:
parallel to the x-axis basically means that it mirrors the x-axis since parallel lines have the same slope. since the question wants the graph with the line that is also below the x-axis, the correct graph would be option 2
Answer:
Option 2 is parallel to the x axis because only option 1 and 2 are a line across and option 1 is 3.2 units above.
The perimeter of a rectangular pool is 336 m.
If the width of the pool is 73 m, what is its length?
Length of the pool:
Answer:
The length of the pool is 462 m.
Step-by-step explanation:
The length of the pool is 462 m. We know this is the answer because, if we plug in the known width and known perimeter into the equation for the perimeter of a rectangle, we get:
73 * 462 = 336
Therefore, the length of the pool is 462 m.

A theater charges $8 for an adult ticket, and $6 for a children's ticket. On a certain day, a total of 255 tickets were sold for a total cost of $1,850. How many more children's tickets were sold than adult tickets?
A. guess, check and revise
B. use a formula
C. work backwards
D. look for a pattern
Answer:
B
Step-by-step explanation:
By making an equation where x = number of adult tickets and y = number of children tickets, we can get 2 equations:
8x + 6y = 1850
x + y = 255
then we solve the equation to get each of the amounts
Denver, Colorado often experiences snowstorms resulting in multiple inches of accumulatedsnow. During the last snow storm, the snow accumulated at (0.8) inch/hour. If the snow54continues at this rate for hours, how much snow will accumulate?
Answer:
43 inches
Step-by-step explanation:
Accumulation rate per hour = 0.8 inch / hour
If the snow continues at that rate for 54 hours ;
To obtain the amount of snow that will accumulate, we multiply the Accumulation rate per hour by the number of hours given ;
Accumulation rate per hour * number of hours
= 0.8 inch/hour * 54 hours
= 43.2 inches
= 43 inches (nearest whole number)
