Answer: multiply 8 on all x number of books read
Step-by-step explanation:
1 is 8 because 8 × 1 is 8
2 is 16 because 8 × 2 is 16
3 is 24 because 8 × 3 is 24
4 is 32 because 8 × 4 is 32
5 is 40 because 8 × 5 is 40
6 is 48 because 8 × 6 is 48
7 is 56 because 8 × 7 is 56
8 is 64 because 8 × 8 is 64
9 is 72 because 8 × 9 is 72
10 is 80 because 8 × 10 is 80
Answer:
Derivative: P’(x) = 200 - 2x
If P’(x) = 0 , x = 100
Therefore P’ is positive and P increases until x = 100
So the maximum units to maximize profits is 100 units
And for 100 units the profit in dollar is:
20000 - 10000 = 10000
10000 dollars
If you multiply 6 times 8 there are 48
Answer: 7740
Step-by-step explanation: take 180(n-45) and n represents the sides
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°
