PolarNik [594]3 years ago

The formula for arc length is:

s= r∅

Given that ∅= 7π/4

and r= 5

Therefore, arc length s= 7π/4 *5 = 35π/4

Answer:  The required arc length will be 27.5 units.

Step-by-step explanation:  We are given to find the arc length with the following information :

\theta=\dfrac{7\pi}{4},~~~\textup{radius},~r=5.

We know that the length of an arc with angle subtended at the center α and radius of the circle r units is given by

\ell=r\alpha.

Therefore, the required arc length will be

\ell=r\theta=5\times\dfrac{7\pi}{4}=\dfrac{35}{4}\times \dfrac{22}{7}=\dfrac{5\times 11}{2}=\dfrac{55}{2}=27.5.

Thus, the required arc length will be 27.5 units.

A 1,000 mL solution of acetic acid contains 26 mL of pure acetic acid. Find the percent concentration of this solution.
Mrac [35]

Given:

Total solution : 1000mL

Pure acetic acid = 26mL

To find:

The percent concentration of given solution.

Solution:

We know that,

\text{Percent concentration}=\dfrac{\text{Pure acetic acid}}{\text{Total solution}}\times 100

Putting the given values, we get

\text{Percent concentration}=\dfrac{26}{1000}\times 100

\text{Percent concentration}=\dfrac{26}{10}

\text{Percent concentration}=2.6

Therefore, the percent concentration of this solution is 2.6%.

F(x + 1) = 3x - 7<br> f(x) = ?<br> Cevabi kitabda=3x-10<br> Nasil yapmiş kitabda
lina2011 [118]

Answer:

<h2>f(x) = 3x + 4</h2>

Step-by-step explanation:

f(x + 1) = 3x - 7

f(x) = f(x + 1 - 1) = 3(x - 1) + 7 = 3x - 3 + 7 = 3x + 4

Check

f(x) = 3x + 4

f(x + 1) = 3(x + 1) + 4 = 3x + 3 + 4 = 3x + 7 CORRECT

Masteriza [31]

Answer:

63 Lights

Step-by-step explanation:

First you can convert the feet to inches:

The length of decorative lights is 264 inches

You can then subtract 16 from 264

264 - 16 = 248

248/4 = 62

Adding one extra light at the end of the string of decorative lights you can get 63 lights on the string
