Answer:

  1/5

Step-by-step explanation:

When the dilation is centered at the origin, the dilation factor is applied to each pre-image coordinate to get the image coordinate.

  k(10, -15) = (2, -3)

  k = 2/10 = -3/-15 = 1/5

The scale factor of the dilation is 1/5.

Answer:

[tex]15360\,\,rupees[/tex]

Step-by-step explanation:

Let sides of the triangle be [tex]a,b,c[/tex]

[tex]a=40\,,\,b=24\,,\,c=32[/tex]

Semi-perimeter (s) = [tex]\frac{a+b+c}{2}[/tex]

[tex]=\frac{40+24+32}{2}\\ =\frac{96}{2}\\=48[/tex]

Area of one tile [tex]=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

[tex]=\sqrt{48(48-40)(48-24)(48-32)}\\ =\sqrt{48(8)(24)(16)}\\ =\sqrt{147456} \\=384\,\,cm^2[/tex]

So,

Area of 20 tiles [tex]=20(384)=7680\,\,cm^2[/tex]

Cost of polishing the floor at the rate of 2 rupees per sq.cm = [tex]7680(2)=15360\,\,rupees[/tex]

Answer:

The opposite of 1/2 is -2/1, which can also be written as -2.

[tex]given \: that \: :[/tex]

[tex]x \: = - 9[/tex]

[tex]then \: 3x \: will \: be : [/tex]

[tex]3 \times x[/tex]

[tex]3 \times - 9[/tex]

[tex] = - 27[/tex]

[tex]∴3x = - 27 \: ( \: x \: = - 9)[/tex]

Answer:G=1/4 or the same as g=0.25

Step-by-step explanation:

Answer:

1/4 is the answer.

Step-by-step explanation:

So first, you subtract the g-9g. You get -2 = -8g, correct?

Next, you divide -2 by -8, you then get -2/-8

This simplifies to 1/4.

Hope this helped. :)

first, love the killua profile picture ! i love hunterxhunter i am currently on season 5, episode 44 or 45 aka 119 or 120 but anyways,

answer:

b = 2

step-by-step explanation:

because its roots are -4 and 2,

and a = 1 [The coefficient of [tex]x^2[/tex]] we know that [tex]x^2 + bx + c = (x - (-4)) (x-2)=(x+4)(x-2) = 0.[/tex]

using the distributive property we get,

[tex]x^2 + 2x - 8 = 0.[/tex]

by equating coefficients (common strategy for partial fractions and undetermined coefficient method of solving ODE), we get b = 2 and c = -8 ( solved c just for fun guess :) ) .

hope this helps :)

To determine the amount of Inventory, we multiply the designated market value with the quantity, then sum all the results up but in the last part,we use the cost per unit instead becuase it is lower than the designated market value.

Answer:

In y intercept form, the equation would be: Y= -1/3x -6

Step-by-step explanation:

In order to find the equation, you can use any points given. In this case, I used (-6,-4) and (-3,-5).

With these points, you must find the slope. The change in our y values is -1 and the change in our x values is +3.

Now we have Y= -1/3x

To find the y intercept, you look on the graph for where there's a point that is lying on y line. In this case (0,-6) is lying on the y line. This means that the Y intercept for our equation is -6. Another example is (0,8), our y intercept would be 8 because the x value is 0!

In conclusion, our equation in y intercept form would be Y= -1/3x-6

Hope this helps!! :)

Answer:

[tex]2x + 11[/tex]

Step-by-step explanation:

1) Expand by distributing terms.

[tex]2x + 6 + 5[/tex]

2) Collect like terms.

[tex]2x + (6 + 5)[/tex]

3) Simplify.

[tex]2x + 11[/tex]

The first step to do this equation is to expand.which means to solve whats inside the parentheses first. If you expand you'll get a answer of 2x + 11.

Answer:

No

Hi There

Your answers are:

4) 12/3

-10) YES!

0/10) 0 (zero)

2 & 3/4 ) 11/4

10 & 1/2 ) 21/2

.3) 3/10

-.16) -4/ 25

3.17) 3 & 17 /100

.3 repeating ) YES

.16 repeating) 1/ 6

-1.2 repeating ) YES!

If a decimal does not terminate or repeat is is not a rational number

Step-by-step explanation:

For 4)

4/1 = 12/x

Ask yourself, how do i get from 4 to 12?

Multiply by 3! HOWEVER, whats done to the numerator MUST be done to the denominator!

4/1 * 3/3 = 12/3

For -10 )

-10/1 = -20/2

Simplify -20/2!

Divide -20 by 2 = -10

-10/1 = -10/1 YES!

For 0/10 )

When you have ZERO tenths, what does that equal? Zero!

For 2 & 3/4ths )

To change to an improper fraction, multiply the 2 by the denominator and add that to the numerator. Put that over the original denominator

(2*4 +3) / 4

8+3 / 4 = 11/4

For 10 & 1/2 )

Repeat what you did for 2& 3/4ths!

(10*2+1)/2

20+1/2

21/2

Answer:

a. 14,000 pesos

b. 23 years

Step-by-step explanation:

Answer:

y=-2/3x+7

Step-by-step explanation:

Since you know the path is parallel to the equation y+-2/3x+12, you already know the slope is -2/3.

It says y is the height above street level, so that is 3. The problem says x is time, which is 6, so all you have to solve for is the y intercept.

3 (y, or the height above street level) = (-2/3) 6 (x, or time) + b (unknown y intercept)

3 = -4 + b

7 = b

So, y = -2/3x + 7
