Answer:
width = 6.5
length= 10
Step-by-step explanation:
area of the pond is 50*50 = 2500 square meters
the walkway is 5 meters wide so the outside dimensions would be 60 meters by 60 meters
area of that is 60 *60 = 3600 meters
area of walkway is 3600 - 2500 = 1100 square feet
number of crates needed: 1100 / 45 = 24.44, round up to 25 crates
25 crates x $74 each = $1,850 total
D = 25 ft is the length of a shadow. L - the length of a tree.
Two angles are 85° and 65° and the third is 180° - ( 65° + 85° ) =
= 180° - 150° = 30°.
We will use the Sine Law:
25 / sin 30° = L / sin 65°
25 / 0.5 = L / 0.9063
25 * 0.9063 = 0.5 L
22.6577 = 0.5 L
L = 22.6577 : 0.5
L = 45.3 ft.
Answer: the approximate length of the tree is 45.3 ft.
Answer:
20 = 6m or m = 20/6 = 10/3
Step-by-step explanation:
Let's say Samantha has s marbles and Paul has m marbles.
We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.
Substitute 20 in for s:
20 = 6m
m = 20/6
Thus, the equation is m = 20/6.
