<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:
B: x=-1
Step-by-step explanation:
5x+6=1
5x+6-6=1-6
simplify
divide by 5 on both sides
x=-1
Answer:
x = 11
Step-by-step explanation:
Properties of a square,
1). Diagonal of a square bisect the opposite angles.
2). All interior angles of a square measure 90°.
From these properties,
m∠PQR = 90°
Since, diagonal QS bisects angle PQR,
m∠PQS = m∠RQS = 45°
(6x - 21)° = 45°
6x = 45 + 21
6x = 66
x = 11
Answer:50 x 2 = 100.
100 ÷ 5 = $20 off.
50 – 20 = $30 sale price.The sale price is $30.
Answer:
Today's price P must be 74% (100% - 26%) of yesterday's price Y. P = $555 = 74%*Y = 0.74*Y. Y = $555/0.74.
