You have to subtract $40 from $68 make sure the larger number is in the front. If you did that all you would get $28.
Answer:2/7 You can solve it with a calculator too
Given:
Denver can plant 3 rows of a certain length with 2 seedlings leftover or 4 rows of the same length with 3 seedling spots left empty.
To find:
The equation for the given problem and its solution.
Solution:
Let x be the length of each row.
Denver can plant 3 rows of a certain length with 2 seedlings leftover.
Total number of seeds he has = ...(i)
Denver can plant 4 rows of the same length with 3 seedling spots left empty.
Total number of seeds he has = ...(ii)
Using (i) and (ii), we get
Isolate variable terms.
Therefore, the required equation is and the values of x is 5. Each row is 5 meters long.
Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then
If y is inversely proportional to x, then
It is given that u varies directly with the square of p and inversely with d. So,
It can be written as:
Where, k is the constant of proportionality.
Therefore, the required equation is .
If the first bird is on top of the bird watcher and the height of the tree is the same, then we form a right triangle with right angle on the second bird.
We can solve the angle of depression by trigonometric functions. So,sin θ = 29.7 / 42.1θ = sin-1 (29.7/42.1)θ = 44.87°
Therefore, the angle of depression of the second bird and the bird watcher is 44.87°.
