C

28

= π

The diameter is equal to twice the radius.

C = 2πr

C = 2(14)π

C = 28π

C

28

= π

Answer and explanation:

Given : The radius of a circle is 14.

To find : Which equation expresses the ratio of the circumference of the circle to the circle's diameter?

Solution :

The circumference of the circle is C=2\pi r

Radius is r=14

The circumference of the circle is C=2\pi\times 14=28 \pi

The circle's diameter is d=2r

The ratio of the circumference of the circle to the circle's diameter is given by,

C:d=2\pi r : 2r

C:d=\pi : 1

Therefore, option B is correct.

Say that Thailand has a workforce of 35,709,487 people, each of whom earns an average salary of (equivalent USD) $8,630 annually
marysya [2.9K]

The income tax rate must be 29%.

Given that,

Thailand has a workforce of 35,709,487 people, each of whom earns an average salary of (equivalent USD) $8,630 annually.

If the Thai government wants to raise $70 billion in tax revenue,

We have to find,

The approximately where should it set the income tax rate?

According to the question,

Thailand has a workforce of 35,709,487 people, each of whom earns an average salary of (equivalent USD) $8,630 annually.

\rm Total \ income = Number \ of \ people \times Income \ per \ person\\\\Total \ income = 35,709,487 \times 8,630\\\\Total \ income = 308,172,872,810

If the Thai government wants to raise $70 billion in tax revenue,

Then,

The income tax rate is,

\rm Tax\  rate = \dfrac{70,000,000,000,}{308,172,872,810}\\\\Tax \ rate = 0.29\\\\Tax \ rate = 29 \ percent

Hence, The income tax rate must be 29%.

Urgent help algebra 2

Slope-intercept you have right:
y=3/4x-7

Point slope form is:
y − y1 = m(x − x1)

so

y +7 = 3/4(x -0)

or

y + 7 = 3/4x

Timed quiz help please! <br> 2 2/5 kilometers in 3 3/4 minuets.
shepuryov [24]

Answer: 16/25 (sorry I'm not really sure bc I'm just  a middle schooler)

Step-by-Step explanation:

2 2/5 km=2.4 kilometers

3 3/4 minutes=3.75 minutes

2.4/3.75=240/375

240/375=48/75=16/25=64/100=0.64

0.64 km/minute (0.64 km per minute)

you can solve the problem using the fractions...

2 2/5=12/5

3 3/4=15/4

(12/5)/(15/4)=(12/5)*(4/15)=48/75=16/25=0.64 again, or you can simplify before multiplying...

(12/5)/(15/4)=(12/5)*(4/15)=(4/5)*(4/5)=16/25...
