What is the answer, What is mCD?
Answer:
In English, we would call these terms the “Greatest Common Denominator” and the “Least Common Multiple”. It looks like in Italian at least, MCM stands for “Minimo Comune Multiplo” (aka Least Common Multiple) and MCD stands for “Maximo Comune Divisor” (aka Greatest Common Denominator).

A = (1/2)(7 units)(7 units) = 49/2 units squared
4b. A cell phone plan costs $200 to start. Then there is a $50 charge each
month. What is the total cost for x months? *
answer:
the equation would be
200 + ( 50 * x ) = total cost
x is variable for the number of months
but lets use the number 2 ( 2 months ) for example
200 + ( 50 * 2 ) =
using pemdas we solve what is in the parentheses first
50 * 2
= 100
then just add the following numbers since they are the only ones left over in the problem
100 + 200
= 300
now we know that in 2 months and if you chose this cell phone plan, you will have to spend 300 dollars even!
hope this helps you and if you ever need anymore help or just not understanding this topic then please feel free to ask me! :)
and just in cause you dont know what pemdas stands for,
parentheses, exponents, multiplication/division ( always start from left to right ), addition/subtraction ( and again always start from left to right )

( 1.) A biker takes off on a course that begins with a small ramp. The biker bikes up a hill and across a flat portion of the course before heading down a steep descent.
( 2.) A driver leaver her house and slows down to make a stop at her neighbor's house. She then drives at a constant speed and stops at a house further down the street. After visiting with her neighbor, she quickly drives back home.
( 3.) A hiker begins hiking, but shortly after realized he left his water bottle in his car. He turns around to get his water bottle and then starts hiking again at a constant rate. The hiker stops for lunch at the furthest point of his hike and then hikes back at a quicker constant rate.
The slope of the curve is positive between the times t=0\text{ s}t=0 st, equals, 0, start a text, space, s, end text, and t=2 \text{ s}t=2 st, equals, 2, start a text, space, s, end text since the slope is directed upward. This means the acceleration is positive.
The slope of the curve is negative between t=2 \text{ s}t=2 st, equals, 2, start a text, space, s, end text, and t=8 \text{ s}t=8 st, equals, 8, start a text, space, s, end text since the slope is directed downward. This means the acceleration is negative.
At t=2\text{ s}t=2 st, equals, 2, start a text, space, s, end text, the slope is zero since the tangent line is horizontal. This means the acceleration is zero at that moment.
Concept check: Is the object whose motion is described by the graph above speeding up or slowing down at time t=4\text{ s}t=4 st, equals, 4, start a text, space, s, end text?
[Show me the answer.]
What does the area under a velocity graph represent?
The area under a velocity graph represents the displacement of the object. To see why to consider the following graph of motion that shows an object maintaining a constant velocity of 6 meters per second for a time of 5 seconds.
To find the displacement during this time interval, we could use this formula
\Delta x=v\Delta t=(6\text{ m/s})(5\text{ s})=30\text{ m}Δx=vΔt=(6 m/s)(5 s)=30 mdelta, x, equals, v, delta, t, equals, left parenthesis, 6, start text, space, m, slash, s, end text, right parenthesis, left parenthesis, 5, start text, space, s, end text, right parenthesis, equals, 30, start text, space, m, end text
which gives a displacement of 30\text{ m}30 m30, start text, space, m, end text.
Now we're going to show that this was equivalent to finding the area under the curve. Consider the rectangle of the area made by the graph as seen below.
The area of this rectangle can be found by multiplying the height of the rectangle, 6 m/s, times its width, 5 s, which would give
\text{ area}=\text{height} \times \text{width} = 6\text{ m/s} \times 5\text{ s}=30\text{ m} area=height×width=6 m/s×5 s=30 mstart text, space, a, r, e, a, end text, equals, start text, h, e, i, g, h, t, end text, times, start text, w, i, d, t, h, end text, equals, 6, start text, space, m, slash, s, end text, times, 5, start text, space, s, end text, equals, 30, start text, space, m, end text
This is the same answer we got before for the displacement. The area under a velocity curve, regardless of the shape, will equal the displacement during that time interval. [Why is this still true when velocity isn't constant?]
\text{area under curve}=\text{displacement}area under curve=displacementstart text, a, r, e, a, space, u, n, d, e, r, space, c, u, r, v, e, end text, equals, start text, d, i, s, p, l, a, c, e, m, e, n, t, end text
[Wait, aren't areas always positive? What if the curve lies below the time axis?]
What do solved examples involving velocity vs. time graphs look like?
Example 1: Windsurfing speed change
A windsurfer is traveling along a straight line, and her motion is given by the velocity graph below.
Select all of the following statements that are true about the speed and acceleration of the windsurfer.
(A) Speed is increasing.
(B) Acceleration is increasing.
(C) Speed is decreasing.
(D) Acceleration is decreasing.
Options A, speed increasing, and D, acceleration decreasing, are both true.
The slope of a velocity graph is the acceleration. Since the slope of the curve is decreasing and becoming less steep this means that the acceleration is also decreasing.
It might seem counterintuitive, but the windsurfer is speeding up for this entire graph. The value of the graph, which represents the velocity, is increasing for the entire motion shown, but the amount of increase per second is getting smaller. For the first 4.5 seconds, the speed increased from 0 m/s to about 5 m/s, but for the second 4.5 seconds, the speed increased from 5 m/s to only about 7 m/s.
Example 2: Go-kart acceleration
The motion of a go-kart is shown by the velocity vs. time graph below.
A. What was the acceleration of the go-kart at time t=4\text{ s}t=4 st, equals, 4, start a text, space, s, end text?
B. What was the displacement of the go-kart between t=0\text{ s}t=0 st, equals, 0, start text, space, s, end text and t=7\text{ s}t=7 st, equals, 7, start text, space, s, end text?
A. Finding the acceleration of the go-kart at t=4\text{ s}t=4 st, equals, 4, start a text, space, s, end text
We can find the acceleration at t=4\text{ s}t=4 st, equals, 4, start a text, space, s, end text by finding the slope of the velocity graph at t=4\text{ s}t=4 st, equals, 4, start a text, space, s, end text.

Two brothers went shopping at a back-to-school sale where all shirts were the same price, and all the shorts too. The younger brother spent $230 on 8 new shirts and 10 pairs of shorts. The older brother purchased 8 new shirts and 4 pairs of shorts and paid a total of $116. How much did each item cost?
Answer:
Younger: 12.78 per item
Older: 9.67 per item
Step-by-step explanation:
Well, if all the shirts and shorts were the same price divide the total price and total amount of items they bought.
Younger Brother:
8 shirts + 10 shorts = 18 items for $230
$230 ÷ 18 items = about 12.78 per item (it comes out to a lot of number so I estimated it the nearest hundredth)
Older Brother:
8 shirts + 4 shorts = 12 items
$116 ÷ 12 items = about 9.67 per item (estimated again)

Calculate the length of the side LN given the following data for 37°.
Sin 37° = 0.602
Cos 37° = 0.790
Tan 37° = 0.754
pls help ASAP
Answer:
It is given that,
Sin 37° = 0.602
Cos 37° = 0.790
Tan 37° = 0.754
To find:
The length of side LN.
Solution:
In a right angle triangle,
[tex]\sin\theta =\dfrac{Perpendicular}{Base}[/tex]
Using this in triangle LMN, we get
[tex]\sin (37^\circ) =\dfrac{LM}{LN}[/tex]
[tex]0.602=\dfrac{6}{LN}[/tex]
[tex]0.602LN=6[/tex]
Divide both sides by 0.602.
[tex]LN=\dfrac{6}{0.602}[/tex]
[tex]LN=9.966777[/tex]
[tex]LN\approx 9.97[/tex]
Therefore, the correct option is C.

back up and begin with a running start.
Answer: Make the ramp longer
making the ramp shorter and making the ramp steeper would be the same, and backing up wouldn't really help
Pickle should make the ramp longer in order to be successful.
Option A is the correct answer.
What is a ramp?The ramp refers to a sloped surface that connects a lower level to a higher level.
We have,
- A longer ramp will provide a more gradual slope, which will make it easier for the cart to move up the ramp.
- If the ramp is too short,
The slope will be too steep and it will be difficult to push the cart up.
- Making the ramp steeper will also make it more difficult to push the cart up.
- Starting with a running start may provide some initial momentum, but it will not address the underlying problem of the ramp being too short.
Thus,
Pickle should make the ramp longer in order to be successful.

Use the Distributive Property to simplify the expression.
1(8+x+4) = 0
Answer:
x + 12 = 0
Step-by-step explanation:
Answer:
x = -12
Step-by-step explanation:
1 x 8 = 8
1 x x = 1x
1 x 4 = 4
rewrite expression
8 + 1x + 4 = 0
combine like terms
8 + 4 = 12
1x + 12 = 0
subtract 12 from both sides
12 - 12 = 0
0 - 12 = -12
1x = -12
divide by 1 on both sides to get x by itself
1x/1 = x
-12/1 = -12
