Answer:
2/5 or 40 percent
Step-by-step explanation:
All we need to solve this problem are the total number of boys and the total number of girls. Since we already know how many boys there are (6) , let's start by finding the girls, which is marked as b. Looking at the chart, we can tell that
8 + a = b
but we don't know what a is yet. How about we find that out first? If we look vertically, we can see that
a + 4 = 5
so
a = 1.
Now, we can find b.
b = 9
To find the probability of selecting a boy, we have to divide the number of boys by the total number of people.
boys/total = 6 / 15
Simplifying, we get the answer
2/5.

Answer:
69100-241/729Step-by-step explanation:
Put the numbers where the variables are and do the arithmetic. Your calculator can help.
1. 6x -2y +5y = 6(10) -2(3) +5(3) = 60 -6 +15 = 69

2. add 16 to find x.
x -16 = 29
x = 45
Then do the substitution:
2(45 +5) = 2(50) = 100

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.
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 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]

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.

Step-by-step explanation:
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).

204
