Given:

The satang coin from Thailand has a radius of about 7 mm.

We need to determine the diameter and circumference of the coin.

Diameter of the coin:

The diameter of the coin can be determined by multiply the radius by 2.

Thus, we have;

$d=2r$

Substituting r = 7, we get;

$d=2(7)$

$d=14 \ mm$

Thus, the diameter of the coin is 14 mm.

Circumference of the coin:

The circumference of the coin can be determined using the formula,

$C=\pi d$

Substituting $\pi=3.14$ and $d=14$ , we get;

$C=(3.14)(14)$

$C=43.96 \ mm$

Thus, the approximate value of the circumference of the coin is 43.96 mm

Answer:

The correct answer is -7.5 years.

Step-by-step explanation:

Given:

Principle amount = 12000

Interest = 4320

time = ?

rate = 4.8 simple interest

Solution:

We know that simple Interest I = (P*t*r)/100

then t = I*100/p*r

putting values in formula:

t = 4320*100/4.8*12000

= 432000/57,600

= 7.5 years

Complete the table of values fory=2x^2+x

Semmy [17]

Complete question:

y = 2x² + 2x - 3

x = -2 -1 0 1 2

Answer:

Complete table of values

x: -2 -1 0 1 2

y: 1 -3 -3 1 9

Step-by-step explanation:

Given;

y = 2x² + 2x - 3

To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.

when, x = -2

y = 2(-2)² + 2(-2) - 3

y = 8 - 4 - 3

y = 1

when x = -1

y = 2(-1)² + 2(-1) - 3

y = 2 - 2 - 3

y = -3

when x = 0

y = 2(0)² + 2(0) - 3

y = 0 - 0 - 3

y = -3

when x = 1

y = 2(1)² + 2(1) - 3

y = 2 + 2 - 3

y = 1

when x = 2

y = 2(2)² + 2(2) - 3

y = 8 + 4 - 3

y = 9

Complete table

x: -2 -1 0 1 2

y: 1 -3 -3 1 9

Answer:

? =6.97

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hyp

sin 35 = 4 / ?

Multiply each side by ?

? sin 35 = 4

Divide each side by sin 35

? = 4/sin 35

? =6.973787182

To the nearest hundredth

? =6.97

Solve for t. t + 19 = 45) it will give u 29 points if u help me!

Oksi-84 [34.3K]

Hi there!

Answer:

t=26

*The answer must have a positive sign.*

Step-by-step explanation:

First, you subtract by 19 from both sides of an equation.

$t+19-19=45-19$

Then, you subtract by the numbers from left too right.

$45-19=26$

Final answer is t=26

I hope this helps you!

Have a nice day! :)
