Answer:

∠ O = 72°

Step-by-step explanation:

the inscribed angle R is half the measure of its intercepted arc NQ , then

arc NQ = 2 × 36° = 72°

the central angle O is equal to the measure of the arc that subtends it , so

∠ O = arc NQ = 72°

En algunos bancos, cuentas de ahorro o incluso en prestamos y empeños podemos observar que se cobra un interés mensual. Esto no significa que todos los intereses deban ser así.

NEED HELP! ASAP! 50 POINTS!

Lerok [7]

Answer:

$y=13\text{ miles per gallon}$

Step-by-step explanation:

We have the two points: (0, 11) and (3, 50).

And we want to find the rate of change in y relative to x, where x is the gallons and y is the miles.

In simple terms, we want to find the slope between the two points.

So, let's use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let (0, 11) be (x₁, y₁) and let (3, 50) be (x₂, y₂). Substitute. Let's also put "miles" in the numerator with the Ys and "gallons" in the denominator with the Xs. This yields:

$y=\frac{50-11\text{ miles}}{3-0\text{ gallons}}$

Subtract and reduce:

$y=39\text{ miles}/3\text{ gallons}=13\text{ miles per gallon}$

And we're done!

Completing the Square: -b/(2a)

Step-by-step explanation:

Step 1: Define

x² - 8x + 15 = 0

Step 2: Solve for x

[Subtraction Property of Equality] Subtract 15 on both sides: x² - 8x = -15
Complete the Square [Addition Property of Equality]: x² - 8x + 16 = -15 + 16
[Complete the Square] Simplify: (x - 4)² = 1
[Equality Property] Square root both sides: x - 4 = ±1
[Addition Property of Equality] Add 4 on both sides: x = 4 ± 1
Evaluate: x = 3, 5

A book sold 31,100 copies in its first month of release. Suppose this represents 7.8% of the number of copies sold to date. How

zvonat [6]

For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
