Answer:

3c + 43 >_ 100

Step-by-step explanation:

Answer:

The answer is 1008 degrees

Step-by-step explanation:

The sum of 7 of the interior angles of a regular decagon is 1008°.

S = (n - 2) × 180°, where n is the number of sides of the regular polygon.

"It is a polygon having ten sides, ten interior angles and ten vertices."

For given example,

We need to find the sum of 7 of the interior angles of a regular decagon.

Number of sides of decagon (n) = 10

Using the formula of sum of interior angles,

⇒ S = (n - 2) × 180°

⇒ S = (10 - 2) × 180°

⇒ S = 1440°

This means the sum of all interior angles of a regular decagon is  1440°.

We know, there are 10 interior angles of regular decagon.

Let  'x' represents the measure of each interior angle of a regular decagon.

⇒ 10x = 1440°

⇒ x = 1440/10

⇒ x = 144°

This means, the interior angle of a regular decagon measures 144°

So, the sum of 7 of the interior angles would be,

7 × 144° = 1008°

Therefore, the sum of 7 of the interior angles of a regular decagon is 1008°.

Answer:

450 miles

Step-by-step explanation:

First you calculate miles per gallon, which you do by dividing 300/20. This gives us 15. So you can go 14 miles on one gallon.

From there you multiply 15 by 30, since you'll be driving 30 miles. This gives us 450 miles.

Step-by-step explanation:

[tex] \frac{300}{x} \times \frac{20}{30} = \frac{20x}{20} \frac{9000}{20} x = 450miles[/tex]

Answer:

400 seconds

Step-by-step explanation:

150/20 m/s

vt = d

t=d/v

t = 3000m / (150/20m/s)

t = 400 sec

Answer:

The constant of proportionality of the equation is 1.5.

Step-by-step explanation:

Equation of proportional measures:

Suppose that y and x are proportional measures. This situation can be equatialized is:

y = ax

In which a is the constant of proportionality.

y = 1.5x. What is the constant of proportionality of the equation?

a = 1.5, so the constant of proportionality of the equation is 1.5.

Answer:

Answer:

B.

Step-by-step explanation:

When you want to move a function on a graph from left to right, you "move" the x, and when moving the x; it's the opposite. So, C would move the function 5 units to the right because it is subtracting.

The correct option will be f(x) = 3^(x - 5)

A translation is a transformation that moves every point in a figure the same distance in the same direction.

Given that, the function f(x) = 3ˣ, being translated 5 units to the left.

Since, the function is being translated in left, therefore, we subtract 5 from x,

i.e. f(x) = 3⁽ˣ⁻⁵⁾

Hence, f(x) = 3⁽ˣ⁻⁵⁾ is the function shows the function f(x) = 3ˣ being

translated 5 units to the left.

Answer:

choice 1) 0, -4/5

Step-by-step explanation:

1/(t² + t) = 1/t - 5

multiply both sides of the equation by (t² + t):

1 = (t² + t)/t - 5t² - 5t

1 = t + 1 - 5t² -5t

-5t² - 4t = 0

t(-5t - 4) = 0

t = 0

-5t = 4

divide both sides by -5:

t = -4/5

Answer:

A sample of 2084 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In an earlier study, the population proportion was estimated to be 0.19.

This means that [tex]\pi = 0.19[/tex]

98% confidence level

So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].

How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 98% confidence level with an error of at most 0.02?

This is n for which M = 0.02. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.02 = 2.327\sqrt{\frac{0.19*0.81}{n}}[/tex]

[tex]0.02\sqrt{n} = 2.327\sqrt{0.19*0.81}[/tex]

[tex]\sqrt{n} = \frac{2.327\sqrt{0.19*0.81}}{0.02}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.19*0.81}}{0.02})^2[/tex]

[tex]n = 2083.4[/tex]

A sample of 2084 is needed.
