Answer:
B -2x - 12y
Step-by-step explanation:
-8x + 6x = -2x
12y - 24y = -12y
-2x - 12y
Answer:
Step-by-step explanation:
Let the base camp is point A and boats' locations after two hours are points B and C.
By connecting the three points together we get a triangle ABC with sides:
- AB = 50*2 = 100 km
- AC = 70*2 = 140 km
The angle between AB and AC is:
- 60 + 50 = 110 degrees (opposite directions from south)
We are looking for the distance BC, which can be found by using the law of cosines:
- BC² = AB² + AC² - 2AB*AC*cos ∠BAC
- BC² = 100² + 140² - 2*100*140*cos 110°
- BC² = 39176.56 (rounded)
- BC = √39176.56 = 197.93 km (rounded)
The distance between the boats is 197.93 km.
Answer:
Volume of a hexagonal pyramid = 588 square meter
Step-by-step explanation:
Given:
Base area of hexagonal pyramid = 147 square meter
Height of hexagonal pyramid = 4 meter
Find:
Volume of a hexagonal pyramid
Computation:
Volume of a hexagonal pyramid = Base area of hexagonal pyramid x Height of hexagonal pyramid
Volume of a hexagonal pyramid = 147 x 4
Volume of a hexagonal pyramid = 588 square meter
