Estimate the amount of the tip by rounding the bill to the nearest 10 dollars before calculating
15% tip on a bill of $483.82
the amount of the tip is approximately $_.
Answer:
My estimate is 73
Step-by-step explanation:
15% ?
____ ______
100 483.82
Steps:
1.First multiply 15 and (483.82).You should get (7257.3).
2.Next you have to divide 7257.3 and 100 which gets you 72.573.
3.Estimate:Round 72.573
73

Use the sliders to change the values of a, b, and cin
the sine function. Which equation has a maximum at
(Pi/4, 3) and a minimum at (pi/4, -3)
y=-3 cos(2x) is the equation has a maximum at (4π , 3) and a minimum at (4π , -3)
What is Trigonometry?The study of correlations between triangles' side lengths and angles is known as trigonometry.
The sine function's parameters, a, b, c, and d, must be adjusted using the sliders.
Now, Finding the equation with a maximum at (4π , 3) and a minimum at (4π , -3) is necessary.
Thus, Setting the values for the slider requires setting a to -3, b to 2, and c to 0.
Hence, The solution, y=-3 cos (2x), should match the equation obtained from the sliders.

Answered correctly on edge
In the morning, Marco sold 12 cups of lemonade for $3. By the end of the day, he had earned $9. How many cups of lemonade did he sell in all?
Kaycee wrote the proportion StartFraction 12 over 3 EndFraction = StartFraction 9 over c EndFraction for this situation. Identify the error and give two ways to write the proportion correctly.
Answer:
Marco earned $2.25.
Step-by-step explanation:
1. If Marco sold 12 cups of lemonade for 3$, we would divide 12 cups and how much he earned from the 12 cups (3$). 12/3 = 4
2. By the end of the day, Marco earned $9. So, 4 cups = 1$. To break it down, 1$ = 100 cents and 100 cents divided by 4 is 25 cents. Cups to Cost. ( 4 : 1 ) and/or ( 1 : 0.25 )
3. 8 cups = 2$ plus 1 cup (0.25) = 2.25.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Answer:
Kaycee did not keep lemonade and dollars in corresponding positions in the ratios of the proportion. The proportion should be 12/3=c/9 or it could be written 3/12=9/c. Dollars should be in the same position and cups should be in the same position across ratios.

Step-by-step explanation:
Solve the equation.
a
-9x + 1 = -x + 17
O x=-8
O x = -2
Ox= 2
O x = 8
The solution of the given equation is x = -2.
What is an Equation?An equation is a mathematical statement containing two expressions on either sides which are connected with an equal to sign.
Either sides of an equation is called as left hand side and right hand side.
Given equation is,
-9x + 1 = -x + 17
We have to find the solution of the given equation.
Take the like terms together.
Subtracting one on both sides,
-9x = -x + 16
Adding x on both sides,
-8x = 16
Dividing by -8 on both sides,
x = -2
Hence the solution is x = -2.

PLEASE HELP!! DUE SOON :( Question: Find the value of x.
Answer:
Ooh man, this was back in geometry I think, I think the answer is 4 if my calculations are correct.
i think the bigger side is twice the size of the smaller side, so 2 times 8 is 16,
16 = 5x - 4
x = 4

Answer:
Line 1: m = 2
Line 2: m = 2
The lines are parallel.
Step-by-step explanation:
First, ensure both lines are in the slope-intercept form given as y = mx + b. where m is the slope of the line.
If the slope of both lines are the same, they are parallel.
If the slope of one is the negative reciprocal of the other, they are perpendicular.
If the slope of both lines are different and one is neither the reciprocal of the other, then they are neither parallel nor perpendicular.
✍️Line 1, y = 2x + 5, is already in the slope-intercept form.
✅The slope of Line 1 is 2
✍️Line 2, y - 3 = 2(x + 15), is in point-slope.
We can decide to rewrite in the slope-intercept form or directly determine the slope as it is given. The slope is 2. But to be sure, let's rewrite as y = mx + b.
y - 3 = 2(x + 15)
y - 3 = 2x + 30
Add 3 to both sides
y = 2x + 33
✅As we can see, the slope of line 2 is 2.
✍️Line 1 and line 2 has the same slope of 2, therefore the lines are parallel.

find the slope of the line (12,-18), (11,12)
Answer:
-30
Step-by-step explanation:
To find slope, subtract two y's and then subtract the x's in the same order.
12-(-18)=30=-30
11-12 -1
You could also switch the order like this...
-18-12=-30=-30
12-11 1
As you can see, both of the ways of solving for slope resulted in -30.

Answer:
False
Step-by-step explanation:
In mathematics, a reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis or plane of reflection. The image of a figure by a reflection is its mirror image in the axis or plane of reflection.
