39/69 = 13/23 is in simplest form
First you do 39 divide by 3 = 13 and do 69 divid by 3 = 23
Answer:
x=31
Step-by-step explanation:
we need to isolate x so we put 48 t the other side to make -x=17-48
we do 17-48 =-31 so -x=-31
x=31
Answer:
Justification:As told in the statement, n stands for the number of bits, and

is the highest number of ways n bits can be arranged in the system.
Now, Antonio wants to show that the character can collect one less key than that. So, that number is

less 1, which is what the formula

- 1 states.
Answer:
<u>405</u>
Step-by-step explanation:
<u>Given</u>
<u>Solving</u>
- a₂ = -3a₁ = -3(5) = -15
- a₃ = -3a₂ = -3(-15) = 45
- a₄ = -3a₃ = -3(45) = -135
- a₅ = -3a₄ = -3(-135) = <u>405</u>
Given:
b1 = 17 ft
b2 = 20 ft
h = 13 ft
r = 17/2 = 8.5 ft
Area of the Semi-circle = 1/2 π r²
= 1/2 (22/7) (8.5²)
= (11/7) (72.25)
= 113.535 ft²
Area of the trapezium = (h) (b1 + b2) / 2
= (13)(17 + 20)/2
= 240.5 ft²
Total area of the amphitheater stage = Area of Semi-circle + Area of the trazezium = 113.535 + 240.5 = 354.035 ft²
