Answer:

Step-by-step explanation:

well i dont know what you are asking the measurment for but as you can see it is a circle which is automatically 360 degrees and than theres a line through the middle which is measurments F TO E which will make each side of the equation 180 automatically so for example;

CAE would be something that equals 180 hope this helps

<h3>Answer: Choice D) 56 degrees</h3>

How I got that answer:

Angle DCE is given to be 62 degrees. By the inscribed angle theorem, It doubles to 124 degrees, which is the measure of central angle DAE.

Note how angles DAF and DAE are a linear pair. This means they are adjacent supplementary angles. So they add to 180

(angle DAF)+(angle DAE) = 180

(angle DAF) + (124) = 180

angle DAF = 180-124

angle DAF = 56

A 0.8-liter bottle of Mexican wine costs 101 pesos. At thatprice, how much would a half-gallon jug of the same wine cost ind

Answer:

$12.18

Step-by-step explanation:

Given:

Cost of 0.8 liter bottle of Mexican wine = 101 pesos

cost of 1 liter bottle of Mexican wine = $\frac{\textup{101}}{\textup{0.8}}$ pesos

Now,

1 Mexican pesos = 0.051 dollars

thus,

cost of 1 liter bottle of Mexican wine = $\frac{\textup{101}}{\textup{0.8}}\times0.051$ dollars

also,

1 gallon = 3.78541 Liter

Thus,

half gallon = $\frac{\textup{3.78541}}{\textup{2}}$ = 1.892705 Liters

therefore,

cost of half gallon jug = $\frac{\textup{101}}{\textup{0.8}}\times0.051\times1.892705$ dollars

cost of half gallon jug of wine = $12.18

The force, F newtons (N) between two particles is inversely proportional to the square of the distance, d m, between them. When

allsm [11]

The force is 1.6N and the distance between them is 1.3 meters

<h3>The force between them</h3>

An inverse variation from force to the square of distance is represented s:

k = Fd^2

Where k represents the variation constant

When F = 10, d = 2.

So, we have:

k = 10 * 2^2

k = 40

Substitute k = 40 in k = Fd^2

Fd^2 = 40

When d = 5, we have:

F * 5^2 = 40

This gives

25F = 40

Divide by 25

F = 1.6

Hence, the force is 1.6N

<h3>The distance between them</h3>

In (a), we have:

Fd^2 = 40

When F = 25, we have:

25 * d^2 = 40

This gives

25d^2 = 40

Divide by 25

d^2 = 1.6

Take the square root of both sides

d = 1.3

Hence, the distance between them is 1.3 meters
