Answer:
Percentage of hits in English,French,Spanish and Japanese are 0.59%,0.16%,0.13% and 0.11% respectively.
Step-by-step explanation:
We have to find the percentage of hits for each version of the website.
The hits for the versions are
- English = 4860
- French = 1350
- Spanish = 1080
- Japanese = 900
<u>Total number of hits = 8190 hits.</u>
Percentage of hits =
Percentage of English =
= 0.59 %
Percentage of French =
= 0.16 %
Percentage of Spanish =
= 0.13 %
Percentage of Japanese =
= 0.11 %
These are the required percentages.

The size of angle PRQ is 15°
Step-by-step explanation:
In any regular polygon of n-sided
- All sides are equal in length
- All angles are equal in measure
- The measure of each interior angle is
- The measure of each exterior angle is
- The sum of the measures of the interior and exterior angle at the same vertex is 180°
∵ PQ and QR are two sides of a regular 12-sided polygon
∴ PQ = QR
∵ PR is a diagonal
∴ ∠PQR is an interior angle of the polygon
- By using the rule of the interior angle above
∵ n = 12
∴ m∠PQR =
∴ m∠PQR = 150°
In Δ PQR
∵ PQ = QR ⇒ sides in a regular polygon
- Δ PQR is an isosceles Δ
∴ m∠PRQ = m∠RPQ ⇒ base angles of an isosceles Δ
The sum of the measures of the interior angles of a triangle is 180°
∵ m∠PQR + m∠PRQ + m∠RPQ = 180°
∴ 150 + m∠PRQ + m∠RPQ = 180°
- Subtract 150 from both sides
∴ m∠PRQ + m∠RPQ = 30
∵ m∠PRQ = m∠RPQ
- Divide their sum by 2 to find the measure of each one
∴ m∠PRQ = m∠RPQ = 30 ÷ 2 = 15°
∴ m∠PRQ = 15°
The size of angle PRQ is 15°
