28) Find the circumference of a circle with a diameter of 2.5 inches. (it = 3.14)

**Answer: Circumference = 7.85 inches**

**Concept:**

Here, we need to know the idea of circumference.

The circumference is the perimeter of a circle. The perimeter is the curve length around any closed figure.

Circumference = 2πr

r = radius

π = constant

**Solve:**

Given information

r = (1/2) d = (1/2) (2.5) = 1.25 inches

π = 3.14

Given formula

Circumference = 2πr

Substitute values into the formula

Circumference = 2 · (3.14) · (1.25)

Simplify by multiplication

Circumference = (2.5) · (2.14)

Circumference = [tex]\boxed {7.85 inches}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

**Step-by-step explanation:**

Using the formulas

C=2πr

d=2r

Solving forC

C=πd=π·2.5≈7.85398in

How do I do this, is the equation 40=ksqrt(65)?

**Answer:**

**Step-by-step explanation:**

Start a little more generally. Carefully find k

distance = k * speed ^2

112 = k*40^2

112 = k * 1600 Divide by 1600

112/1600 = k

k = 0.07

Now do the question you are asked to do.

distance = k * speed^2

distance = 0.07 * 65^2

distance = 295.75

Now having done that, you can set up a proportion.

d1 / d2 = k speed1^2/kspeed2^2 Cancel the ks

112/d2 = 40^2 / 65^2 Cross multiply

112 * 65^2 = 40^2 * d2 Divide by 40^2

112 * 65^2/40^2 = d2 Expand the squares

112 * 4225 / 1600 = d2

295.75 = d2

The second way is shorter, but I suggest the long way until you get comfortable with it.

Look at the triangle below.

Which equation is equivalent to the law of cosines?

A

a2=c2−2cx+h2

B

a2=c2−2cx+x2+h2

C

a2=c−x2+h2

D

a2=c2−x2+h2

**Answer:**

I believe the answer is B. a^2 = c^2 - 2cx + x^2 + h^2

**Step-by-step explanation:**

The law of cosines states: c^2 = a^2 + b^2 - 2bc * cos(C). If we plug in the values from the diagram, we'll have (c-x)^2 = a^2 + h^2 -2ah * cos(90)

cos(90) = 0, so now we have just (c-x)^2 = a^2 + h^2

Let's expand this to c^2 -2cx + x^2 = a^2 + h^2

Isolate a^2 and we now have **a^2 = c^2 -2cx + x^2 + h^2**

Point V is on line segment UW. Given VW = 5x - 4, UV = 2x, and UW = 5x, determine the numerical length of VW

**Answer:**

VW = 6

**Step-by-step explanation:**

To find x, set up the following equation:

(5x - 4) + (2x) = 5x

Solve out left side

7x - 4 = 5x

Subtract 5x from both sides

2x - 4 = 0

Add 4 to both sides

2x = 4

Divide both sides by 2

x = 2

Plug into 5x - 4

5(2) - 4

10 - 4

6

Answer:

6

Step-by-step explanation:

5x - 4 + 2x = 5x

7x - 4 = 5x

-4 = -2x

2 = x

5(2) - 4

10 - 4

4. In a class of 35 students, 20 offer Physics,

18 offer Chemistry and 2 offer neither

Physics nor Chemistry

1) Illustrate the information on a Venn

diagram

il) How many students offer all the two

subjects?

1) How many students offer Physics!

1) How many students offer only one

subject

**5 students** offers all the two subjects.

Student that offers Physic only = **15 students**

Student that offers chemistry only = **13 students**

Students that offers only one subject = **28 students**

Total student in the class = **35**

**20 offer physics.**

18 offer chemistry

2 offer neither physics nor chemistry.

Therefore,

x = student that offer both subject

**35 = 20 + 18 - x + 2**

35 - 2 - 20 - 18 = -x

-5 = -x

**x = 5**

Therefore, **5 students** offers all the two subjects.

Student that offers Physic only = 20 - 5 = 15

Student that offers chemistry only = 18 - 5 = 13

Students that offers only one subject = 13 + 15 = 28
