Answer:
$30.00
Step-by-step explanation:
Jack's original salary before it was doubled was $15.00 per day.
Let's assume Jack's original salary is "x" dollars per day.
According to the given information, Bill makes $30.00 per day, which is twice as much as Jack made before his salary was doubled. So, before Jack's salary was doubled, he made "x" dollars per day.
After Jack's salary was doubled, he makes 2 * x = 2x dollars per day.
Now, we know that Bill makes $30.00 per day, which is equivalent to the new salary of Jack after it was doubled.
So, we can set up an equation:
2x = $30.00
To find the value of "x," we can divide both sides by 2:
x = $30.00 / 2
x = $15.00
Therefore, Jack's original salary before it was doubled was $15.00 per day.

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of a right cylinder that
has the same base and height as the cone?
Answer:
The volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.
Step-by-step explanation:
Given that,
The volume of a right circular cone is 300 cubic inches
We need to find the volume of a right cylinder that has the same base and height as the cone.
Volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
And volume of a cylinder is given by :
[tex]V'=\pi r'^2 h'[/tex]
If the base and height of cone and cylinder are same, r=r' and h=h'
[tex]\dfrac{V}{V'}=\dfrac{1/3\pi r^2 h}{\pi r'^2h'}\\\\=\dfrac{1/3\pi r^2 h}{\pi r^2h}\\\\\dfrac{V}{V'}=\dfrac{1}{3}\\\\V'=3V[/tex]
So, the volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.

Speaking from experience, when you work with rational (fraction) polynomials on paper, it often tends to take up a bit of space and get messy. Therefore, I'd suggest you tried solving one equation at a time if you have the same issue.
Also, sometimes you may come across values that you don't want to type again in your calculator (like non-recurring decimals). For these, use the store function on your calculator to get maximum accuracy. With TI-84 and 83s, you can save values as letters (X, Y, etc.). Hence, you can just write out your equation using these, and hence significantly reduce the risk of typing the number wrong, while saving yourself some time.

Step-by-step explanation:
In this graph the y-intercept of the line is (Blank). The equation of the line is y=(Blank) x (Blank) .
Answer:
In the graph, the y-intercept is -2. The equation of the line is [tex] y = x - 2 [/tex]
Step-by-step explanation:
The equation of the line can be written in the slope-intercept form, y = mx + b.
First we need to find:
The slope = m
the y-intercept = b
Using two points on the line, (0, -2) and (2, 0) the slope can be calculated as follows:
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 -(-2)}{2 - 0} = \frac{2}{2} = 1 [/tex]
The y-intercept is simply the point at which the line intercepts the y-axis. It is the value of y when x = 0.
Therefore, the y-intercept, b, = -2.
Substitute m = 1 and b = -2 into [tex] y = mx + b [/tex].
Thus, the equation if the line would be:
[tex] y = (1)(x) + (-2) [/tex]
[tex] y = x - 2 [/tex]

Which is the graph of the line y − 2 = 3(x − 1)?
Answer:
d i have this ? to so thats how ik
Step-by-step explanation:
so the problem is y-2=3(x-1)
in this problem you have to rmb the forumla
y-y1=m(x-x1)
to find the points
so in the equation -1 would be x1 thats one point but you turn the -1 into a postive one dont know why thats just what my tutor said
so know you know one of the points (1,
to find the other you have to seaarch for y1 which from using the forumla you would know is -2 but you have to turn it in to a postive
This actually the answer for a deff problem but if you got the problem thats asking for which quarterpoints then this is it
so the points are (1 , 2)
The equation of a line in slope-intercept form is expressed as y = mx + b
m is the slope of the line
b is the y-intercept
Given the equation y − 2 = 3(x − 1), express in the form y = mx + b
y - 2 = 3x - 3
y = 3x - 3 + 2
y = 3x - 1
Graph the equation y = 3x - 1 as shown:

Answer:
Step-by-step explanation: I’m on this lesson right now, I took a guess at it because I don’t understand it at all (I’m supposed to be financial literacy, then trig) but I know that the first one is E and that the second one is NOT A, the third one is NOT D, and the fourth one is NOT F.

The following points of the figure match with the following polar coordinates:
(- 4, - 3π/4) → E(4, 7π/4) → F(4, 3π/4) → C(- 4, - 7π/4) → D
How to match polar coordinates with a given figure
Polar coordinates are described by magnitude (r) and direction (θ), in radians. When the magnitude is negative is antiparallel to the positive case, that is, the direction of the form is π radians more in the direction orientation.
Based on the comparison between the given points and graphs, we have the following conclusions:
(- 4, - 3π/4) → E
(4, 7π/4) → F
(4, 3π/4) → C

Mega Melt's food truck is known for their grilled cheese sandwiches. Yesterday, they made 56 grilled cheese sandwiches in 2 hours. Today, Mega Melt will be open for 3 hours.
If they make the grilled cheese sandwiches at the same rate, how many of them will Mega Melt's food truck make today?
Answer:
84
Step-by-step explanation:56 ÷ 2 ≡ 28
28 × 3 ≡ 84
Mega Melt's food truck can make 84 grilled sandwiches in 3 hours today.
Given that, yesterday, Mega Melt's food truck made 56 grilled cheese sandwiches in 2 hours.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here,
The number of sandwiches grilled in 1 hour = Total number of sandwiches grilled/Number of hours
= 56/2
= 28
Number of sandwiches grilled in 3 hour = 28×3
= 84
Therefore, Mega Melt's food truck can make 84 grilled sandwiches in 3 hours today.
