let's take 6 to the other side ~

[tex] \\ \bold{\implies \: r = 12 \times 6} \\ \\ \implies \: \bold\pink{r = 72}[/tex]

hope helpful ~

Answer:

r=72

Step-by-step explanation:

multiply both sides by 6 —> 12x6=r/6x6

12x6=r

73=r

Answer:

x-intercept: [tex]\frac{3}{13}[/tex]  or about 0.231 which is also written as ([tex]\frac{3}{13}[/tex], 0)

y-intercept: 3 which is also written as (0, 3)

[Solution One]

   We can find the answer by graphing. See attached. The points at which the line intersects the different axes is the answer.

[Solution Two]

   We can solve by plugging into the equation. We will do this by setting the other variable, the one we aren't solving for, to 0.

For the x-intercept:

   y = −13x + 3

   (0) = −13x + 3

   0 - 3 = -13x + 3 - 3

   -3 = -13x

   [tex]\frac{3}{13}[/tex] = x

For the y-intercept:

   y = −13x + 3

   y = −13(0) + 3    

   y = 3

The rule which represents the translation from the pre-image (Δabc), to the image (Δa'b'c') is (x, y) → (y, x).

A triangle simply refers to a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.

Based on this triangle, we can deduce the following points:

By critically observing the triangle, we can also deduce that points were swapped as (x, y) → (y, x) and this is a reflection across line y = x.

Answer:

Tn= -9+(n-1)×3

Step-by-step explanation:

d= t2-t1 =t3-t2....

=-6-(-9)=3

We realize that this is an arithmetic sequence

Therefore Tn= a + (n-1)d, whereby a if the first term= - 9,d=3

Tn=-9+(n-1)×3

Answer:An=-9+3(n-1)

Step-by-step explanation:

First, find the common difference (the amount you are adding each time). You can find this by taking the second term and subtracting the first term.  Now, identify the first term.  This is the first number in your list.  Finally, plug the first term in for A1 and the common difference in for d in the equation an=a1+d(n-1)  Note: Leave the variable n as part of the equation.

The volume of the unit cell that is a simple cubic is 1.1661622e⁻²⁰.

Volume is the space occupied by a three-dimensional object.

By the formula of volume of atom

[tex]\rm Volume(atom) = \dfrac{4}{3} \times \pi \times r^3\\Volume(atom) = \dfrac{4}{3} \times \pi \times (161 \times 10^-^2^3)^3\\Volume(atom) = 2.1574e^-^2^1[/tex]

There are total 4 atoms, in a  FCC unit cell.

The total volume is

[tex]2.1574e-21 \times 4 = 8.6296e^-^2^1[/tex]

Volume of a unit cell will be

[tex]\dfrac{8.6296e-21}{0.74} = 1.1661622e^-^2^0[/tex]

Thus, the volume of the unit cell is [tex]\rm 1.1661622e^-^2^0[/tex]

To solve this problem, we have to use the area of both gauze or the dimensions on each gauze and compare them. we can see that the sheets are not similar as they have different areas.

The area of a rectangle is given as the product between the length and it's width.

Data;

[tex]area = length * width[/tex]

In the first gauze, the area is given as 45in^2 and we have value of the length. To find the width of the first gauze can be calculated as

[tex]A = length * width\\width = \frac{area}{length} \\width = \frac{45}{9} \\width = 5in[/tex]

We can see that the width are not equal so is their length.

But if we would truly compare them, the accurate way to do that is by their area

The area of the second gauze is given by

[tex]a = 3 * 4 = 12in^2[/tex]

From the above calculations, we can see that the sheets are not similar as they have different areas.

Step-by-step explanation:

the sum of the interior angles of a triangle is 180

so,

70+47= 117

180-117= 63

Answer:

Your answer is 63°

Explanation:

47 + 70 + angle C = 180° (Sum of all angles of a triangle is 180).

117 + angle C = 180°

So,angle C =180 - 117= 63°

The division equation that has a quotient of 13 is 1/1/13 = 13

The given parameters are:

A division equation is represented as:

Dividend/Divisor = Quotient

Substitute 13 for the Quotient

Dividend/Divisor = 13

Recall that:

Unit fraction = 1/n

So, we have:

Dividend/1/n = 13

Let n = 13.

So, we have:

Dividend/1/13 = 13

This gives

13 * Dividend = 13

Divide both sides by 13

Dividend = 1

So, we have:

1/1/13 = 13

Hence, the division equation is 1/1/13 = 13

Answer:

Hamburger is 320 calories. Pack of french fries is 280 calories

Step-by-step explanation:

Represent Hamburgers as H and pack of French Fries as P then set up the equations

5H+2P=2160

If he starts paying after four years, the worth of the loans by then is b. $31,616.16

This refers to the amount collected from a lender to be repaid after a given time, usually with added interest.

Hence, we can see that:

The effective monthly interest rate is:

i = 0.053/12 = 0.0044

The effective annual interest rate is:

i = (1 + 0.0044)^12 -1 = 0.0543

The present worth of all the loans is:

P = 6125 + 6125 (1 + 0.0543)^-1 + 6125 (1 + 0.0543)^-2 + 6125(1 + 0.0543)^-3

P = $22,671.40

If he pays them prompty, then the total lifetime cost would be

P = 22671.40 (1 + 0.0543)^4 = $31,616.16
