Answer:
a. 360.323 m
b. 
Step-by-step explanation:
Distance covered from A to B = speed x time
= 110 x 2.8
= 308 m
Distance covered from B to C = speed x time
= 110 x 1.7
= 187 m
The sum of angles at B = 
+ 
= 
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.
= 
+ 
- 2ac Cos B
Sot hat;
= 
+ 
- 2(187 x 308) Cos
But, Cos = 0
So that,
= +
= 34969 + 94864
= 129833
b = 
= 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
= 
= 
= 
Sin A = 
= 0.5190
⇒ A = 
0.5190
= 
The bearing of the plane from its original location = +

Answer: 10.3 pounds of CO2 is produced
Step-by-step explanation:
Assuming there are 30 days in a month, if the microwave is run for 10 minutes per day, then the number of minutes for which the microwave is run in a month is
30 × 10 = 300 minutes
We would convert from minutes to hours
60 minutes = 1 hour
Therefore,
300 minutes = 300/60 = 5 hours
Also,
1000 watts = 1 kW
Therefore,
1500 watts = 1500/100 = 1.5kw
Therefore, the number of kWh is
1.5 × 5 = 7.5 kWh
If 1.37 pounds CO2 per kWh, then
If 1kWh = 1.37 pounds CO2, then
7.5 kWh = 7.5 × 1.37 = 10.3 pounds rounded to the nearest tenth
Answer:
Width of rectangular garden = 10 meter
Step-by-step explanation:
Given;
Area of rectangle garden = 150 m²
Length of rectangular garden = 5 meters more than its width
Find:
Width of rectangular garden
Computation:
Assume;
Width of rectangular garden = W
So,
Length of rectangular garden = 5 + W
Area of rectangle garden = length x width
(W)(W + 5) = 150
W² + 5W = 150
W² + 5W - 150 = 0
W² + 15W - 10W - 150 = 0
W(W + 15) - 10(W + 15) = 0
(W + 15)(W - 10)
So,
W = -15, W = 10
Width of rectangular garden = 10 meter
