Which of the following graphs shows a direct variation (proportion)?

Answer:

$960.5 dollars the answer is $960.5 the tax was 110.5

Answer:

Step-by-step explanation:

The center of a circle is the midpoint of any diameter. The midpoint of a segment has coordinates that are the average of the coordinates of the segment end points.

The length of the radius is the distance from the center to an end point of a diameter. Alternatively, it is half the length of the diameter.

__

Center = (A +B)/2 = ((7, -5) +(-1, 10))/2 = (6, 5)/2 = (3, 2.5)

Radius = 1/2|AB| = 1/2√((7 -(-1))² +(-5 -10)²) = 1/2√(64 +225) = 1/2√289

= 17/2 = 8.5

The center of the circle is (3, 2.5), and the radius is 8.5 units.

__

Additional comment

The differences of diameter end point coordinates are 8 and 15, suggesting the Pythagorean triple {8, 15, 17} will come into play. It does.

Answer:

No solution (C)

Step-by-step explanation:

System of Linear Equations given :

  [1]    7x + 4y = 16

  [2]    42x + 24y = 110

Solve by Substitution :'

// Solve equation [2] for the variable  y

 [2]    24y = -42x + 110

 [2]    y = -7x/4 + 55/12

// Plug this in for variable  y  in equation [1]

  [1]    7x + 4•(-7x/4+55/12) = 16

  [1]    0 = -7/3 =>  NO solution

Answer:

2.67857142855

Step-by-step explanation:

every M of cloth costs 0.17857142857rs (10/65=0.17857142857)

So, 15m of cloth costs 2.67857142855rs (0.17857142857*15= 2.67857142855)

Answer:2.7rs

Step-by-step explanation:

First find the cost of one m:

We can set it up as a fraction in the form of cloth (mm)/cost(rs)

=
56m/10rs

let x be the cost in rs of 1m:

1m/x

This is kind of like a ratio where 56/56=1 so therefore 10/56 (because whatever you do to the top you do to the bottom) will give us x or in other words the cost of 1 meter of cloth:

so after dividing both 56 and 10 by 56 we get:

1/0.18 (it would be a longer decimal but always try to round it if you can!)

That mean 1m of cloth costs 0.18 rs

So now let’s apply the same rule as before (treating the fraction as a ratio and doing the same on both top and bottom and let’s apply it again to find the cost of 15 meters!)

1m * 15

————-

0.18 * 15

=

15m

———-

2.7rs

therefore the cost of 15 m is 2.7rs

confirm with your teacher wether they want you to round it or not however.

Hope this helps!

Answer:

D)  y = -2x - 6

Step-by-step explanation:

Given:

Using the point-slope form of a linear equation: [tex]\mathsf{y-y_1=m(x-x_1)}[/tex]

Answer:

r = p - q

Step-by-step explanation:

Write the two given vectors using i and j components.

i = unit vector in x direction

j = unit vector in y direction

p = -i - 3j

q = 3i - 4j

Now how can you combine these two vectors and get r when

r = -4i + j?

Adding p and q gives this:

p + q = -i - 3j + 3i - 4j = 2i - 7j

That is not r, so the addition of the vectors p and q does not work.

How about subtraction?

Start with -i from p and subtract 3i from q. You do get -4i which is the x-component of r.

Then start with -3j from p and subtract -4j from q. You get -3j - (-4j) = -3j + 4j = j which is the y-component of r.

That subtraction works.

p - q = -i - 3j - (3i - 4j) = -i - 3j - 3i + 4j = -4i + j which is exactly what r is.

Answer: r = p - q

Answer:

24 is the answer

Step-by-step explanation:

To solve this problem, we first do two thirds of 180, and then we do one fifth of the solution you got for "two thirds of 180"

[tex]\mathrm{Two\:thirds\:of\:180 = (\frac{2}{3}) 180\:\:or\:\:\frac{2}{3}\times180}[/tex]

[tex]\mathrm{Turn\:\frac{2}{3}\:into\:a\:decimal,\:by\:dividing\:2\:by\:3}[/tex]

[tex]\mathrm{0.6666666666666667\times180}[/tex]

[tex]\mathrm{Multiply\:0.6666666666666667\:and\:180}[/tex]

[tex]\mathrm{120}[/tex]

Now we do one fifth of 120

[tex]\mathrm{One\:fifth\:of\:120 = (\frac{1}{5})120\:or\:\frac{1}{5}\times120}[/tex]

[tex]\mathrm{Turn\:\frac{1}{5}\:into\:a\:decimal,\:by\:dividing\:1\:by\:5}[/tex]

[tex]\mathrm{0.2\times120}[/tex]

[tex]\mathrm{Multiply\:0.2\:and\:120}[/tex]

[tex]24[/tex]

So the answer to "What is one fifth of two thirds of 180", would be 24

By multiplying the number by the corresponding fractions, we can see that the fifth part of two-thirds of 180 is 24.

The fifth part of two-thirds of 180 is 24.

To calculate it:

Step 1: Find two-thirds of 180, Just multiply the fraction 2/3 by the number

(2/3) * 180 = 2 * 180 / 3 = 360 / 3 = 120

Step 2: Find the fifth part of the result from Step 1, similar like we did above, multiply the number by the fraction 1/5.

(1/5) * 120 = 120 / 5 = 24

So, the fifth part of two-thirds of 180 is 24.
