The width is 3m because 3*7 is 21m^2. Also they said the length is 4 more than the width (3+4=7)
Answer:
The answer is "0.45385".

The time is taken to reach the coast 
The time is taken to reach Q after reaching the coast 
Total time, 
This has to be minimum,
x=0.45385
Answer:
The answer to your question is the slope of line e is 
Step-by-step explanation:
If two lines are parallel they have the same slope.
If two lines are perpendicular their slopes are reciprocals and of different signs.
In this question, line d is parallel to line e, which means that they have the same slope.
Answer:
Not sure if this was meant to be a multi choice question, but I'll try help anyway.
As long as you times the denominator and the numerator by the same number, many fractions can be of the same value as 16/-3.
For example, a potential answer to this could be 32/-6.
If we simplify this, we still get 16/-3.
They're different fractions, but of the same value.
Hope this helps!!
Estimation is the process of making quick mental calculation of a value, quantity, or number.
We basically do estimation every day of our lives.
For example, we want to order several pizzas. We know that each pizza costs between $5 to $10. We order 3 pizza pies; Pie 1 = $6; Pie 2 = $8; Pie 3 = $9.
In getting an estimate, we either overestimate or underestimate. We know that whether a product of an estimate is overestimated or underestimated by the direction of the rounded up numbers.
We overestimate, when we round up the numbers
We underestimate, when we round down the numbers.
Overestimate: $10 x 3 pizza = $30 total cost
Underestimate: $5 x 3 pizza = $15 total cost
Actual cost: $6 + $8 + $9 = $23
In estimating expenses, it is better to overestimate. This gives us an allowance when incidental expenses incur.
In estimating income, it is better to underestimate. It gives us a more realistic value of the income.
