Answer:

$26\pi\text{ inches}\approx 81.64\text{ inches}$

Step-by-step explanation:

We have been given an image of a circle . We are asked to find the length of arc ZV.

We will use arc length formula to solve our given problem.

$\text{Arc length}=\frac{\theta}{180}\times \pi r$ , where, r represents the radius of the circle.

$r=\frac{90}{2}=45$

$\text{Arc length ZV}=\frac{104}{180}\times \pi\times 45$

$\text{Arc length ZV}=0.57777777\times \pi\times 45$

$\text{Arc length ZV}=26\pi$

$\text{Arc length ZV}=81.64$

Therefore, the length of arc ZV is 81.64 inches.

Table: <u> Algebra | No algebra | Total</u>

Physics | 4 Step 1: 8 12

No physics |Step 2: 15

Total | 19 30

We look for the number of people who are in algebra and no physics or physics and no algebra.

1. 12 - 4 = <em>8</em>

2. 19 - 4 = <em>15</em>

3. We find the total of those numbers: <em>15 + 8 =</em> 23

The weight, w, of a spring in pounds is given by 0.9 times the square root of the energy, E, stored by the spring in joules. If

frutty [35]

For this case we have the following equation:
$w = 0.9* \sqrt{E}$
Where,
w: The weight of a spring in pounds
E: the energy stored by the spring in joules.
Substituting values we have:
$w = 0.9* \sqrt{12}$
Making the corresponding calculation:
$w=3.12$
Answer:
the approximate weight of the spring in pounds is:
$w=3.12$

Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply.

blagie [28]

<h3>Option D</h3><h3>The expression can be used to find the price of a $400 telescope after a 32% markup is: 400 + 400 (0.32 )</h3>

<em><u>Solution:</u></em>

Given that,

Price of telescope = $ 400

Mark up = 32 %

To find: Cost after mark up

The formula used is:

<h3>Cost after mark up = Price of telescope + 32 % of Price of telescope</h3>

Therefore,

Cost after mark up = 400 + 32 % of 400

$\text{Cost after mark up } = 400 + \frac{32}{100} \times 400\\\\\text{Cost after mark up } = 400 + 0.32 \times 400\\\\\text{Cost after mark up } = 400 + 128\\\\\text{Cost after mark up } = 528$

Thus cost after mark up is $ 528 and expression is 400 + 400 (0.32 )

Find a single expression that represents the area of the outer ring of the circle if the area of the whole circle is represented

sp2606 [1]

Answer: The answer is $A_o=2\pi\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Step-by-step explanation: Given that the area of the whole circle is represented by the expression

$A_c=25x^2-12x-9.$

We are to find the area of the outer ring of the circle, i.e., to find the circumference of the circle.

Now, if 'r' represents the radius of the circle, then we have

$A_c=\pi r^2\\\\\Rightarrow \dfrac{22}{7}r^2=25x^2-12x-9\\\\ \Rightarrow r^2=\dfrac{7}{22}(25x^2-12x-9)\\\\\Rightarrow r=\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Thus, the area of the outer ring is

$A_o=2\pi r=2\pi\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Now, use your research to decide which business is the best choice for this community.

larisa86 [58]

Answer:

Step-by-step explanation:

the best business for this area is The Shoe Hut. This is the case for several reasons. First, there is less competition for custom sporting goods, as the supply in the area is lower. Survey data shows that there are more individuals who desire custom outdoor sporting goods than there are people who desire more coffee shops. Finally, the overall capital required to start and maintain The Shoe Hut is lower. Less equipment is needed, any building can be rented, and if an employee cannot be hired immediately, I can run the store on my own.
