1,284 because you have to divide the students in half because it is every two students. And each pair gets three bottles.

What are the coordinates of the point that is 1/6 of the way from a(14,-1) b(-4,23)

Nimfa-mama [501]

Answer:

$\text{The coordinates of point is }P(a,b)=(\frac{80}{7}, \frac{17}{7})$

Step-by-step explanation:

$\text{Given the coordinates of point that is }\frac{1}{6}\text{ of the way from a(14, -1), b(-4, 23)}$

$\text{If a point }P(a, b)\text{ divides the line joining two points }(x_1,y_1)\text{ and }(x_2, y_2)\\ \text{ in the ratio m:n internally, then the coordinates of point P are given by}$

$P(a,b)=(\frac{mx_2+nx_1}{m+n}, \frac{my_2+ny_1}{m+n})$

The two points given are a(14, -1), b(-4, 23) and ratio m:n=1:6

$P(a,b)=(\frac{1(-4)+6(14)}{1+6}, \frac{1(23)+6(-1)}{1+6})$

$P(a,b)=(\frac{80}{7}, \frac{17}{7})$

Hey can you please help! posted picture of question

frosja888 [35]

The solution of the system can be x - 3y = 4 only if both the equations can be simplified to x - 3y = 4.

This will mean that both the equations will result in the same line which is x - 3y = 4 and thus have infinitely many solutions.

Second equation is:

Qx - 6y = 8
Taking 2 common we get:

(Q/2)x - 3y = 4

Comparing this equation to x- 3y = 4, we can say that

Q/2 = 1
So,
Q = 2

Therefore, the second equation will be:

2x - 6y = 8

PLEASE HELP ASAP !!

ololo11 [35]

Answer:

MK

Step-by-step explanation:

ML is the short side of right triangle MLK. MJ is the hypotenuse of right triangle MKJ. This gives you a clue that the ratios of interest are the short side to the hypotenuse. All these right triangles are similar, so ...

ML/MK = MK/MJ . . . . . ratio of short side to hypotenuse is the same

ML·MJ = MK² . . . . . . . cross multiply

MK = √(ML·MJ) . . . . . the geometric mean of ML and MJ is MK

The sum of three numbers $x$ ,$y$, $z$ is 165. When the smallest number $x$ is multiplied by 7, the result is $n$. The value $n$

babymother [125]

You're given

<em>x</em> + <em>y</em> + <em>z</em> = 165

7<em>x</em> = <em>n</em>

<em>n</em> = <em>y</em> - 9

<em>n</em> = 9 + <em>z</em>

and you want to find <em>xyz</em>.

Solve the last three equations for <em>x</em>, <em>y</em>, and <em>z</em> :

7<em>x</em> = <em>n</em> → <em>x</em> = <em>n</em>/7

<em>n</em> = <em>y</em> - 9 → <em>y</em> = <em>n</em> + 9

<em>n</em> = 9 + <em>z</em> → <em>z</em> = <em>n</em> - 9

Substitute <em>x</em>, <em>y</em>, and <em>z</em> into the first equation and solve for <em>n</em> :

<em>n</em>/7 + (<em>n</em> + 9) + (<em>n</em> - 9) = 165

<em>n</em>/7 + 2<em>n</em> = 165

<em>n</em> + 14<em>n</em> = 1155

15<em>n</em> = 1155

<em>n</em> = 77

Now solve for <em>x</em>, <em>y</em>, and <em>z</em> :

<em>x</em> = 77/7 = 11

<em>y</em> = 77 + 9 = 86

<em>z</em> = 77 - 9 = 68

Then the product is

<em>xyz</em> = 11 • 86 • 68 = 64,328
