<u>Given</u>:
The satang coin from Thailand has a radius of about 7 mm.
We need to determine the diameter and circumference of the coin.
<u>Diameter of the coin:</u>
The diameter of the coin can be determined by multiply the radius by 2.
Thus, we have;
Substituting r = 7, we get;
Thus, the diameter of the coin is 14 mm.
<u>Circumference of the coin:</u>
The circumference of the coin can be determined using the formula,
Substituting and , we get;
Thus, the approximate value of the circumference of the coin is 43.96 mm
Answer:
If he sells $2500 worth of merchandise, his salary is $800.
Step-by-step explanation:
You can find a function that gives you his salary as a function of the sales.
You have two points: (100, 500) and (700, 575).
y = mx + b
m = (575 - 500)/(700 - 100) = 75/600 = 0.125
Now use point (100, 500) to find b.
y = mx + b
500 = 0.125(100) + b
500 = 12.5 + b
b = 487.5
y = 0.125x + 487.5
If he sells $2500, then x = 2500.
y = 0.125x + 487.5
y = 0.125(2500) + 487.5
y = 800
If he sells $2500 worth of merchandise, his salary is $800.
I’m pretty sure it’s 14 km. Hope I helped :) Since I did 56 divided by 4 since it will be one cm is 14 km.
