Jeff has 242 DVDs. He has 2 shelves that can each hold 120 DVDs. Does he need to buy another shelf
Answer:
Here's my way
Step-by-step explanation:
he has 242, and 2 shelves for 120
120 + 120 = 240,
which leaves 2 off.
so, either you can put:
"Yes, because he has 2 remaining" (Not recommended)
Or
"No, because he put 240 on the shelves , he can put the other 2 somewhere else" (Recommended)
let f(x)=|2x+10| and g(x)=|2x-24|. find all the values of x for which f(x)=g(x).
Answer:
8.5
Step-by-step explanation:
two cases:
1) 2x + 10 = 2x - 24, 10 = -24, impossible!
2) 2x + 10 = -(2x - 24)
2x + 10 = -2x - 24
4x = 34
x = 34/4 = 17/2 = 8.5

Are they similar or why are they not
Answer:
Yes they are similar due to the parallel lines of XY & BC. So, technically, the small and big triangle both will share the same base angles because corresponding angles are equal. Thus, angle AYX will be equal to angle YCB, for example.
In addition, two shapes are similar if one is an enlargement of another.

solve for p..........
Answer:
the answer is p = 15
Step-by-step explanation:
first you set the equation to 2p + 9 = 3p - 6
then solve out the equation by adding 6 to both sides
the equation will now look like this, 2p + 15 = 3p
now you subtract 2p from both sides
the equation now looks like 15 = p
I always flip my equations so I can read it better,
p = 15

Two vehicles, a car and a truck, leave an intersection at the same time. The car heads east at an average speed of 30 miles per hour, while the truck heads south at an average speed of 40 miles per hour. Find an expression for their distance apart d (in miles) at the end of t hours.
Step-by-step explanation:
the car distance to the intersection will be
30t (30 miles for every hour).
the truck distance to the intersection will be
40t (40 miles for every hour).
the distance between the car and the truck will always be the Hypotenuse of a right-angled triangle with the legs being the actual distances from the starting intersection.
so, we use Pythagoras :
d² = (30t)² + (40t)² = 900t² + 1600t² = 2500t²
d = sqrt(2500t²) = 50t
so, their distance will increase 50 miles every hour.

Answer:
First you need to make 3 1/2 into a improper fraction so you multiply 3 x 2 and then add 1 which is 7/2. Next you need to divide it by 5/8. So to divide fraction you have to do K.C.F. (Keep, change, flip). So you keep the 7/2 change the division symbol to a multiplication symbol. and then flip the 5/8 into 8/5. So the whole problem would be 7/2 x 8/5. next you just multiply.
7 x 8 = 56
2 x 5 = 10
next you just need to simplify into the smallest fraction and you can simplify both by 2. So 56 / 2 = 28 and 10 / 2 = 5. That's how the solution is 28/5.
Also, the value of the expression 5 x 8/5 is 25/8.
Answer:
make 3 1/2 into a improper fraction by multiplying the 3 and the 2 in the denominator together and then add 1 in the numerator to get 7 then make it 7/2 since the 2 was the denominator in the mixed fraction. Then keep the 7/2 the same turn the division symbol to a multiplication symbol then turn the 5/8 into 8/5 by flipping it then multiply. 7×8= 56 2×5=10 now you have 56/10 so you need to simplify. 2 is common between 56 and 10 so you multiply 56/10 and 2 together. 56÷2= 28 and 10÷2= 5 so now it is 28/5.

The number of classified documents has increased approximately linearly from 8.2 million documents in 2001 to 17.4 million documents in 2005. Let n be the number
of documents (in millions) labeled as classified in the year that is tyears since 2000. Find
an equation of a linear model to describe the data.
Answer:
n -8.2 = 2.3(t -1)
Step-by-step explanation:
You are given definitions for the variables t and n, along with two data points:
(t, n) = (1, 8.2) and (5, 17.4)
The slope of the line between these points is ...
m = (y2 -y1)/(x2 -x1)
m = (17.4 -8.2)/(5 -1) = 9.2/4 = 2.3
The equation can be written in point-slope form as ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
n -8.2 = 2.3(t -1) . . . . a linear model describing the data
______
Additional comment
If we eliminate the parentheses and add 8.2, we get the point-slope equation ...
n = 2.3t +5.9
Find the average of -4, -8, -12, 0, and -6.
Find the distance between (−4, −3) and (−2, 0). Round your answer to the nearest tenth.
Answer:Given the two points you entered of (-4, -3) and (-2, 0), we need to calculate 8 items:
Item 1: Calculate the slope and point-slope form:
Slope (m) = y2 - y1
x2 - x1
Slope (m) = 0 - -3
-2 - -4
Slope (m) = 3
2
Calculate the point-slope form using the formula below:
y - y1 = m(x - x1)
y - -3 = 3/2(x + 4)
Item 2: Calculate the line equation that both points lie on.
The standard equation of a line is y = mx + b where m is our slope, x and y are points on the line, and b is a constant.
Rearranging that equation to solve for b, we get b = y - mx. Using the first point that you entered = (-4, -3) and the slope (m) = 3/2 that we calculated, let's plug in those values and evaluate:
b = -3 - (3/2 * -4)
b = -3 - (-12/2)
b = -6

b = 6

This fraction is not reduced. Using our GCF Calculator, we see that the top and bottom of the fraction can be reduced by 6
Our reduced fraction is:
1
0.33333333333333
Now that we have calculated (m) and (b), we have the items we need for our standard line equation:
y = 3/2x + 3
Item 3: Calculate the distance between the 2 points you entered.
Distance = Square Root((x2 - x1)2 + (y2 - y1)2)
Distance = Square Root((-2 - -4)2 + (0 - -3)2)
Distance = Square Root((22 + 32))
Distance = √(4 + 9)
Distance = √13
Distance = 3.6056
Item 4: Calculate the Midpoint between the 2 points you entered. Midpoint is denoted as follows:
Midpoint =
x2 + x1
2
,
y2 + y1
2
Midpoint =
-4 + -2
2
,
-3 + 0
2
Midpoint =
-6
2
,
-3
2
Midpoint = (-3, -3/2)
Item 5: Form a right triangle and calculate the 2 remaining angles using our 2 points:
Using our 2 points, we form a right triangle by plotting a 3rd point (-2,-3)
Our first triangle side = -2 - -4 = 2
Our second triangle side = 0 - -3 = 3
Using the slope we calculated, Tan(Angle1) = 1.5
Angle1 = Atan(1.5)
Angle1 = 56.3099°
Since we have a right triangle, we only have 90 degrees left, so Angle2 = 90 - 56.3099° = 33.6901
Item 6: Calculate the y intercept of our line equation
The y intercept is found by setting x = 0 in the line equation y = 3/2x + 3
y = 3/2(0) + 3
y = 3
Item 7: Determine the parametric equations for the line determined by (-4, -3) and (-2, 0)
Parametric equations are written in the form (x,y) = (x0,y0) + t(b,-a)
Plugging in our numbers, we get
(x,y) = (-4,-3) + t(-2 - -4,0 - -3)
(x,y) = (-4,-3) + t(2,3)
x = -4 + 2t
y = -3 + 3t
Calculate Symmetric Equations:
x - x0
z
y - y0
b
Plugging in our numbers, we get:
x - -4
2
y - -3

The distance between (-4, -3) and (-2, 0) rounded to the nearest tenth is approximately 3.6 units.
What is coordinate geometry?A coordinate plane is a 2D plane created by the junction of the x-axis and y-axis, two perpendicular lines. A coordinate system in geometry is a way to use one or more integers or coordinates to determine the positions of the points.
The distance between two points (x1, y1) and (x2, y2) in a 2-dimensional plane is given by the distance formula:
D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]
Using this formula, we can find the distance between (-4, -3) and (-2, 0) as follows:
D = √ [ ( 0 + 3)² + (-2 + 4 )² ]
D= √(2² + 3²)
D = √(13)
D ≈ 3.6
Therefore, the distance between (-4, -3) and (-2, 0) rounded to the nearest tenth is approximately 3.6 units.
