Answer:
9). x = 36.9°
10). x = 18.3°
Step-by-step explanation:
9). By applying tangent rule in the given triangle,
tan(x) = 
tan(x) = 
x = 
x = 36.87°
x = 36.9°
10). By applying sine rule in the given triangle,
sin(x) = 
sin(x) = 
x = 
x = 18.32
x ≈ 18.3°
Answer: 0.000274 dragon fly per day.
Step-by-step explanation:
First convert the 10 years into days:
10 × 365 = 3650 days.
This means that one dragon fly dies every 3650 days.
Now, to find how many that dies in a day:
1 ÷ 3650 = 0.000274, corrected to three significant figure.
Looks more like a probability question.
Multiple: 15 * 3 = 45
Multiple: 15 * 12 = 180
Add: 45 + 180 = 225
Unary plus: +15 = 15
Multiple: 225 * 15 = 3375
= (3375)
Multiple: 5 * 7 = 35
Add: +(35) = 35
= (35)
Answer:
D 20 *1.10 * 1.05
Step-by-step explanation:
We have 19.8 tons of wheat. That is close to 20 tons
We increase by 9.8 percent. 9.8% is close to 10%
When we increase, that is 100% of what we had plus the increase, so we multiply by 100 +10% or 110%. In decimal form that is 1.1
20 *1.10
Then the next year we increase by 5.1%. That is close to 5%
We have 100% plus the 5% or 105%, which in decimal form is 1.05
We multiply what we had (20 *1.10) by 1.05
20 *1.10 * 1.05
This is the total amount we have
