Answer:
18.2%
Step-by-step explanation:
The total number of trees in the wood = 420 + 160 + 300
= 880 trees
∴ The percentage of the oak trees =
= %
= %
= 18.181818...%
In 1 decimal place = 18.2%
Hope this helps!!
Answer:
No of these answers has a slope of . My guess is B becasue its close to
unless the 5 is supposed to be negative
Step-by-step explanation:
You have to use the slope formula
(,
), (
,
)
(4, 0), (-2, 10) you have to simplfy, the answer will be
(10, -2), (0, 4) you have to simplfy, the answer will be
(4, 2), (10, 4) you have to simplfy, the answer will be
(-4, -10),(0, -2) you have to simplfy, the answer will be
The distance travelled from the starting point is 29 km , the bearing is 344 degree
The missing diagram is attached with the answer.
<h3>What is Bearing Angle ?</h3>It is the horizontal angle between the object and another object.
It is given that the car starts from point travels for 30km on a bearing of 145, then 10 km on a bearing of 250
(a) the distance travelled from the starting point
It can be understood from the diagram that
To determine the distance , b is to determined4
By applying Cosine rule
b² = a² +c²-2ac cos
b² = 10² +30² - 2* 30*10 cos75
b² = 100+900 -600* 0.2588
b² = 100-155.2914
b² = 844.7
b = 29 km
Therefore the distance travelled from the starting point is 29 km.
(b) the bearing of the starting point from the car.
To determine the bearing ,
angle C has to be determined
By sine rule
sin C / c = sin B / b
sin C = sin 75 * 30 / 29
sin C = 0.9970
C = sin⁻¹ 0.9970
C = 85.59 degree
angle C = α +70 degree
α = 15.59 degree
Bearing = 70 + 20 + 9 0 + 90+74 = 244 degree
