Answer:
2/9
12.5%, 30% ,45%
Step-by-step explanation:
Possible outcomes
W = wild
S = sandy shores
G = green hills
W6 W7 W10
S6 S7 S10
G6 G7 G10
There are 9 outcomes
2 are over a week without hills (W10 and S10) and
P(10 days not at hills) = # more than 7 days no hills/total
=2/9
We need all the numbers in the same form, I will change to decimal
1/8 = .125
30% = .30
.45
Smallest to largest
.125 <.30 <.45
1/8 < 30% < .45
Changing to percent form
12.5%, 30% ,45%
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°
