since our denominator in 6/15 is 15, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:
100 ÷ 15 = 6.6666666666667
Once we have that, we can multiple both the numerator and denominator by this multiple:
6 x 6.6666666666667/15 x 6.6666666666667
= 40/100
Now we can see that our fraction is 40/100, which means that 6/15 as a percentage is 40%.
We can also work this out in a simpler way by first converting the fraction 6/15 to a decimal. To do that, we simply divide the numerator by the denominator:
6/15 = 0.4
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.4 x 100 = 40%
And there you have it! Two different ways to convert 6/15 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.
Answer:
40%
Step-by-step explanation:
6/15 = 0.4 = 40%
All these mean the same them, but what we are looking for is a percentage, which is 40%.

six times a number is 21 less than nine times the same number
Answer:
7
Step-by-step explanation:
6*7=42
9*7=63
63-42
Answer:
number is 7
Step-by-step explanation:
let the number be n , then
6n = 9n - 21 ( add 21 to both sides )
21 + 6n = 9n ( subtract 6n from both sides )
21 = 3n ( divide both sides by 3 )
7 = n
That is the number is 7

Find the product of (x − 3)2. X2 6x 9 x2 − 9 x2 − 6x 9 x2 9.
Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex](x-3)^2[/tex] is [tex]x^2 - 6x + 9[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
For the given case, the product needed can be calculated as:
[tex](x-3)^2 = (x-3) \times(x-3) = x(x-3) - 3(x-3) = x^2 - 3x - 3x + 9\\\\(x-3)^2 = x^2 - (3+3)x + 9 = x^2 - 6x + 9[/tex]
(coefficients of like terms were added)
Thus, the product result of given expression is

Decide whether the given ordered pair is a solution to the system of equations.
-5x+y=12
y=-x
(-2,2)
Answer:
no
Step-by-step explanation:
Doesn't add to 12
[tex] - 5x + y = 12[/tex]
Add both sides 5x
[tex] - 5x + 5x + y = 5x + 12[/tex]
[tex]y = 5x + 12[/tex]
&
[tex]y = - x[/tex]
Thus :
[tex] - x = 5x + 12[/tex]
Add both sides x
[tex] - x + x = 5x + x + 12[/tex]
[tex]0 = 6x + 12[/tex]
Subtract both sides 12
[tex]0 - 12 = 6x + 12 - 12[/tex]
[tex] - 12 = 6x[/tex]
Switch sides
[tex]6x = - 12[/tex]
Divide both sides by 6
[tex] \frac{6x}{6} = \frac{ - 12}{6} \\ [/tex]
[tex]x = - 2[/tex]
We found the x-coordinate of the solution point ; to find the y-coordinate we just need to put the value of x in one 0f the given equations :

Answer:
1. 4/5, 3/5, 4/3 || 2. x = 13.78
Step-by-step explanation:
1)
Sin = Opposite/Hypotenuse = 16/20 = 4/5
Cos = Adjacent/Hypotenuse = 12/20 = 3/5
Tan = Opposite/Adjacent = 16/12 = 4/3
So the answer is 4/5, 3/5, 4/3
2) The unknown side is the opposite, and 21 is the hypotenuse. Opposite/Hypotenuse is the sine function.
Sin(41) ≈ 0.656
0.656 = x/21
x = 13.776
The closest answer to this is 13.78
Is 5x+2 equivalent to 5x+2x ?

I don't think so
Step-by-step explanation:
If I remember (based on memory) it's not equivalent
Reasoning: there's a different amount of Xs
Answer:
Please answer my question if you can, and gl understanding this! <3
Step-by-step explanation:
No, for if we subtract them, when we cancel out the 5x, 2, the integer, will not be equal to 2x, for not only is 2 already there, it is also being multipled by an integer. It possibly can equal though, if x was either 0, or positive 1, but if the x is not given, then no, they're not equivalent.
Given sin 0 and angle 0 is in Quadrant II, what is the exact value of cos 0 in
simplest form? Simplify all radicals if needed.
sin = 3/7
1 = sin²0 + cos²0
cos²0 = 1 - 9/49
cos²0 = 40/49
cos0 = √(40) / 7
since its in Quadrant 2 the sin is positive and cos is negative
cos0 = - √(40) / 7

what means "average" ?
well, the average of a defined set of data points is the sum of the data divided by the number of data points (or samples).
that way you get a mean value for each time the system is "measured" (a data point is created).
each new measurement / data point changes the mean value (or average).
this is used all the time - in sports statistics (e.g. the average score of a team), in daily life (like the average height of a human being that defines sizes of clothes, beds, chairs, tables, even the typical height of ceilings and so on).
the average of these 8 data points is therefore :
(36+37+34+23+47+27+31+21)/8 = 256/8 = 32
so, if he wants to raise his average score to 35 with the results of the next 2 games, this has 2 things to be considered :
1. the number of days points will be then 8+2=10 (and not just 8).
2. we need to add 2 data points, so that the sum of all 10 data points divided by 10 is then 35.
(36+37+34+23+47+27+31+21+x+y)/10 = 35
(36+37+34+23+47+27+31+21+x+y) = 350
x + y = 350 - 256 = 94
that means, he has to score a total of 94 points in the next 2 games.
it does not matter, how many in any single game, as long as the sum of both games is 94.
since the question is phrased "how many in each of the next 2 games", we simply take the target average of these 2 games.
remember, sum/amount = 94/2 = 47.
so, he would have to score 47 points in each of the next 2 games to raise his general average score to 35.

Micah jogs on a path at the park at 5 miles per hour. He has jogged 2 miles when Luke starts running on the same path at 5 miles per hour. If they maintain their pace, when will Luke catch up to Micah?
Answer:
no because micah started before and they are running at the same pace.
Step-by-step explanation:
If they maintain their pace, Luke will not catch up to Micah because the gap of the 2 miles will be maintained.
What is the application of subtraction?In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that Micah jogs at a 5 mph pace along a park trail. Luke begins running on the same path at a speed of five miles per hour after he has jogged two miles.
After 2 kilometers of jogging by Micah, Luke begins running along the same route. Luke moves at a 5 mph speed.
Because Micah and Luke move at the same speed. There will be a 2-mile separation between them. Luke will not catch up to Micah
Thus, if they maintain their pace, Luke will not catch up to Micah because the gap of the 2 miles will be maintained.

Express $18\sqrt 8$ in the form $a\sqrt b$, where $a$ and $b$ are integers and $b$ is as small as possible.
By simplifying the given expression we will get that:
18*√8 = 36*√2
How to find an equivalent expression?
Here we start with:
18*√8
We can rewrite 18 as:
18 = √324
Replacing that in our expression we get:
√324*√8 = √(324*8) = √(2,592)
Now we need to rewrite 2,592 as the product of a square number and a non-square number (such that the non-square number is the smallest possible one).
If we divide 2,592 by 2, we get:
2592/2 = 1296
Then we can rewrite:
√2592 = √(2*1296) = √2*√1296 = √2*36
So this is the expression we wanted:
18*√8 = 36*√2
