0.11 acres can be planted per pound of seed
<em><u>Solution:</u></em>
Given that it takes 63 pounds of seed to completely plant a 7 acre field
To find: acres can be planted per pound of seed
Let "x" be the acres which can be planted per pound of seed
Therefore, from given question,
63 pounds of seed = 7 acre field
1 pound of seed = "x" acre field
This forms a proportion and we can solve the sum by cross multiplying
Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction
Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction
Set the two products equal to each other
Solve for the variable
Thus 0.11 acres can be planted per pound of seed
no this relation is not a function, because for each input (x), there is no output (y)
Answer:
a x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
sqrt(7x) [ sqrt(x) - 7sqrt(7)]
Distribute
sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)
We know that sqrt(a) sqrt(b)= sqrt(ab)
sqrt(7x^2) - 7sqrt(7^2 *x)
Now lets separate out the perfect squares
sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)
x sqrt(7) - 7*7sqrt(x)
x sqrt(7) - 49sqrt(x)
The length of rectangle is 15 feet and width is 7 feet.
Step-by-step explanation:
Given,
Width of rectangle = w
Length of rectangle = 2w+1
Perimeter = 44 feet
Perimeter = 2(Length+Width)
Dividing both sides by 6
The width of rectangle is 7 feet.
Length of rectangle = 2(7)+1 = 14+1 = 15 feet
The length of rectangle is 15 feet and width is 7 feet.
