Answer:
The dimensions of the vegetable patch is 8 m by 7 m.
Step-by-step explanation:
Area of a vegetable patch is 56 square meters and the perimeter is 30 m.
If l is length and b is breadth, then area and perimeter of a rectangle is given by :
Substituting the values in the above formulas as :
and
We need to solve equation (1) and (2) to find the values of l and b such that :
Equation (2), l = 15 - b
Equation (1) becomes,
If b = 7 m, so, l = 8 m
If b = 8 m, l = 7 m
So, the dimensions of the vegetable patch is 8 m by 7 m.
The common denominators of ¹/₄ and ⁷/₁₀ are; 20 and 40
<h3>How to find the denominator?</h3>
The numerator of a fraction is the top value while the denominator of a fraction is the value at the bottom.
Now, we want to find the common denominator of ¹/₄ and ⁷/₁₀.
The common denominator can't be less than 4 or 10 and so has to be at least two terms that are divisible by 4 and 10. The next two common denominators that are greater than 10 but divisible by both 4 and 10 are 20.

Answer:
The length of the ramp must be at least 14.71 feet
Step-by-step explanation:
Given
<em>See attachment for complete figure</em>
Required
Length of the ramp (z)
To do this, we consider sin of angle A (
).
So, we have:
This gives:
Make z the subject
<em>The length of the ramp must be at least 14.71 feet</em>
1.65 i think but i might be wrong
In 1 minute, 4 litre water leaves = 4*1000 cubic cm = 4000
so, the height decrease = Volume/area =
hence water level in cm falling per min = 0.318
hence water level in cm falling per hr= 0.318 * 60 = 19.09
