Let the Addison's candy count be a and Ronny's be r.

Then a = r - 15. This is an equation.

If you had a second equation, you could replace a with the expression (r - 15), which in itself is not an equation.

Let Ronny's candy be x and Addison's candy be y. Then it would read y=x-15.

This is an equation because this is saying that Ronny's amount of candy minus 15 is equal to amount of candy that Addison has. Once there is a useful equal then it is equation.

Answer/Step-by-step explanation:

3.a. length of AC.

Hypotenuse = AC

Opposite side to 60° = 7

Therefore, $sin(60) = \frac{7}{AC}$

$AC*sin(60) = \frac{7}{AC}*AC$

$AC*sin(60) = 7$

$AC = \frac{7}{sin(60)}$

$AC = 8.1$ (to nearest tenth)

b. Length of BC

Hypotenuse = BC

Opposite side to 50° = 7

Therefore, $sin(50) = \frac{7}{BC}$

$BC*sin(50) = \frac{7}{BC}*AC$

$BC*sin(50) = 7$

$BC = \frac{7}{sin(50)}$

$BC = 9.1$ (to nearest tenth)

c. Length of AB

Use the law of sines to find AB

$\frac{BC}{sin(A)} = \frac{AB}{sin(C}}$

m<C = 180 - (60 + 50) (sum of angles in a triangle) = 70°

m<A = 60°

BC = 9.1

AB = ?

$\frac{9.1}{sin(60)} = \frac{AB}{sin(70)}$

Cross multiply

$9.1*sin(70) = AB*sin(60)$

Divide both sides by sin(60)

$\frac{9.1*sin(70)}{sin(60)} = \frac{AB*sin(60)}{sin(60)}$

$\frac{9.1*sin(70)}{sin(60)} = AB$

$9.9 = AB$ (nearest tenth)

$AB = 9.9$

Which statement or statements apply to a bond which is selling at a premium?

SSSSS [86.1K]

Answer:

The best option is:

(a) I and II only

Step-by-step explanation:

Each kind of bond has a face value, usually known as par value. If a bond sells above the par value, it is a premium bond, if it sells below the par value, it is a discount bond. Hence first statement is true.

If a bond has a selling rate of 100, it means it is selling at its par value. For example if a bond has a par value of $100, then a selling rate of 100 means it sells at 100$, a selling rate of 90 means it sell at 90$, a selling rate of 120 means it sells at $120. For a premium bond, the selling rate is always above 100. Hence second statement is true.

Premium bonds are mostly sold by corporations, but alot of scheme of trading premium bonds have also been introduced by governments all around the world. We can say that the statement can be true for some specific country, but globally speaking, the statement is false.

Two cities are 252 miles apart. How far are the two cities from one another on a map with a scale of 1/4 inches: 18 miles?

tekilochka [14]

Answer:

3.5 inches

Step-by-step explanation:

create a proportion:

inches / miles = inches / miles

let 'x' = distance in inches

1/4 = x

18 252

18x = 252(1/4)

18x = 63

x = 63 / 18

x = 3.5
