17. Mike has $50 more than Kemone has. Together they have $730. How much does Kemone have?
Answer:
340
Step-by-step explanation:
$730 - $50 = $680
$680 / 2 = 340
they both have an equal of 340 and then mike adds in 50 more so:
340 + 340 = 680 + mike's $50 = $730.

A 0.68 kg tennis ball is given an angular momentum of 2.72 X 10-3 kg.m2/s when struck by a racquet. If its radius of gyration is 2 cm what is its angular velocity?
50 POINT QUESTION!! Any help is appreciated, thank you!
Answer:
The angular velocity of the tennis ball is 10 radians per second.
Step-by-step explanation:
The tennis ball can be represented as a particle, the angular momentum ([tex]L[/tex]), in kilogram-square meter per second, of the tennis ball is described by the following formula:
[tex]L = m\cdot r^{2}\cdot \omega[/tex] (1)
Where:
[tex]m[/tex] - Mass of the tennis ball, in kilograms.
[tex]r[/tex] - Radius of gyration, in meters.
[tex]\omega[/tex] - Angular velocity, in radians per second.
If we know that [tex]m = 0.68\,kg[/tex], [tex]r = 0.02\,m[/tex] and [tex]L = 2.72\times 10^{-3}\,\frac{kg \cdot m^{2}}{s}[/tex], then the angular velocity of the tennis ball is:
[tex]\omega = \frac{L}{m\cdot r^{2}}[/tex]
[tex]\omega = \frac{2.72\times 10^{-3}\,\frac{kg\cdot m^{2}}{s} }{(0.68\,kg)\cdot (0.02\,m)^{2}}[/tex]
[tex]\omega = 10\,\frac{rad}{s}[/tex]
The angular velocity of the tennis ball is 10 radians per second.

1- The acceleration of a particle is defined by the relation a = 6 ft/s 2. Knowing
that s =-32 ft when t = 0 and v= -6 ft/s when t = 2 s, determine the velocity, the
position, and the total distance traveled when t = 5 s.
help fast
Answer:
The initial velocity of the particle is
v' = -6 - 6.2 = -18 ft/s
at t = 5s, the velocity is v = -18 + 6.5 = 12 ft/s
the position is
[tex]x = - 32 - 18 \times 5 + \frac{1}{2} \times 6 \times 5 {}^{2} = - 47 \: ft[/tex]
the total distance traveled is
[tex]s = | \frac{12 {}^{2} - 18 {}^{2} }{2 \times 6} | = 15 \: ft[/tex]

1 light second into Kilometers
Answer by using two significant figures
Answer:
3.0 x 10^5 km
Step-by-step explanation:
c = 299,792,458 metres per second
c = 299,792 km per second
1 light second = 299,792 km
To two significant figures
300,000 km
3.0 x 10^5 km
In 1 light second there are [tex]3\times 10^5[/tex] kilometers.
[tex]1 \text{light seconds}=3.0\times 10^5 km[/tex]
Step-by-step explanation:
The definition of speed is the distance covered per unit time.The speed of the light in a vacuum is [tex]3.0\times 10^8 m/s[/tex]..The 1 light second is defined as the distance traveled by light in 1 second in free space.To find:
Value of 1 light second into Kilometers
Solution:
Speed of light in space = [tex]3.0\times 10^8 m/s[/tex]
This means that in 1 second light travels [tex]3.0\times 10^8 m/s[/tex].
1 m = 0.001 km
The distance traveled by the light in Km in a second will be:
[tex]3\times 10^8 m= 3\times 10^8\times 0.001 km =3.0\times 10^5 km[/tex]
So, from this, we can conclude that in 1 light second there are [tex]3\times 10^5[/tex] kilometers.
[tex]1 \text{light seconds}=3.0\times 10^5 km[/tex]

You know that 4 notebooks and 3 pens cost $96, while 2 pens and 2 notebooks cost
$54. How many dollars are 8 notebooks and 7 pens worth?
Answer:
Let p be the number of pens and let n be the number of notebooks.
4 notebooks + 3 pens cost $96 so 4n + 3p = 96
2 notebooks + 2 pens cost $54 so 2n + 2p = 54
We find n and p by solving the system of linear equations:
4n + 3p = 96
2n + 2p = 54
4n + 3p = 96
4n + 4p = 108 (we multiply this by 2 to cancel out 4n in both equations)
We then subtract the two equations:
(4n + 3p) - (4n + 4p) = 96 - 108
-p = -12
p = 12
So, a pen costs 12 dollars. We can use p to find n. We substitute 12 for p in one of our earlier equations:
2n + 2p = 54
2n + 2(12) = 54
2n + 24 = 54
2n = 30
n = 15
So, a notebook costs 15 dollars and a pen costs 12. Now, we need to find the cost of 8 notebooks and 7 pens:
8n + 7p = ?
8(15) + 7(12) = ?
120 + 84 = 204.
Thus, 8 notebooks and 7 pens cost 204 dollars (why is it so expensive lol).
Answer:
204

what is the value of y in the following system of equations ? 2x + 3y = 6 2x + y = -2
y = 4
Step-by-step explanation:
2x + 3y = 6. #1
2x + y = -2. #2
Subtract Eq 2 from Eq 1,
3y - y = 6 - (-2)
2y = 8
or
y = 4
Answer:
y = 4
Step-by-step explanation:
2x + 3y = 6
2x + y = -2
Let's set the second equation equal to y. This means that y will be alone on one side of the equal sign.
2x + y = -2
Subtract 2x from both sides.
y = -2x - 2
Now that we have y as an expression, plug it into the first equation.
2x + 3y = 6
2x + 3(-2x - 2) = 6
Distribute the 3 across the parentheses by multiplying.
2x - 6x - 6 = 6
Combine like terms.
-4x = 12
Divide both sides by -4.
x = -3
Now we have solved x.
To solve for y, plug x back into one of the equations.
y = -2x - 2
y = -2(-3) - 2
Multiply.
y = 6 - 2
Subtract.
y = 4
Check your answer by plugging both values back into the original equations.
2x + 3y = 6
2(-3) + 3(4) = 6
Multiply.
-6 + 12 = 6
Add.
6 = 6
Your answer is correct.

A paper company sells paper for $1.50 per package. They have an overhead cost of $1800. Write an equation which depicts their situation.
Answer:
x = 1.50p - 1,800
Step-by-step explanation:
The equation that depicts their situation is -
1.50[tex]x[/tex] - 1800 = 0
We have a paper company sells paper for $1.50 per package with an overhead cost of $1800.
We have to write an equation which depicts their situation.
What is Overhead cost?Overhead cost to the company are the expenses other than the expenses during the generation of any product or service by that company. These expenses are somewhere needed and a certain amount of money is spent on them independent of the fact how much profit your product or service is generating. Concluding, we can say -
Overhead cost = Unwanted expense to the company
According to question -
Let's assume that the company sells [tex]x[/tex] pieces of paper for $1.50.
The overhead expenses = $ 1800
Hence, the equation that depicts their situation is -
1.50[tex]x[/tex] - 1800 = 0

Which figure is described below?
The locus of points in a plane
equidistant between y = 5 and
y = -3.
A. 1 line
B. 1 plane
C. 2 planes
D. 2 lines
============================================================
Explanation:
The graph of y = 5 is the horizontal line through 5 on the y axis. Two points on this line are (0,5) and (1,5).
Similarly, the graph of y = -3 is the same idea, but the horizontal line goes through -3 this time. Two points on this line are (0,-3) and (1,-3)
Let's say we're at (0,5). Directly below this point, on the other line, is (0,-3). The midpoint of (0,5) and (0,-3) is (0,1)
The midpoint of (1,5) and (1,-3) is (1,1)
We form a horizontal line through (0,1) and (1,1). This is the locus of points equidistant from the lines y = 5 and y = -3. It's the middle line halfway between the two given lines. Think of it as the median of the highway (the two shoulders of the highway being y = 5 and y = -3).
So that's why the answer is A) 1 line
------------
Side note: any time we have parallel lines like this, the locus of points equidistant from the two lines is always one single line, and it's the median/middle line as described above. This applies to diagonal parallel lines as well, and vertical parallel lines.

The area of the given rectangle is 10 1/8 units².
What is Surface Area?The region is the space taken up by a flat, two-dimensional surface. Its unit of measurement is the square. A three-dimensional object's surface area is the area occupied by its exterior surface. It is also measured in square units.The total surface area is the area encompassing the base(s) and the curving part. It is the whole area that the surface of the object takes up. A shape with a curved base and surface has a total area equal to the sum of the two areas.
As per the given data:
Measurement of the rectangle is given by
2 1/4 units by 4 1/2 units
= 2 1/4 × 4 1/2 units²
To find the area of a rectangle:
Area = length × width
From the given data
length = 4 1/2 units
width = 2 1/4 units
Area = 2 1/4 × 4 1/2 units²
= 9/4 × 9/2 units²
= 81/8 units²
= 10 1/8 units²
Hence, The area of the given rectangle is 10 1/8 units².
