Answer:
No solution
Step-by-step explanation:
A = (b1 + b2)h/2
A = 35 cm²
h = 16 cm
b1 = 25 cm
b2 = ?
35 = (25 + b2)(16)/2
70 = (25 + b2)(16)
70 = 400 + 16b2
16b2 = 330
b2 = 330/16 = -20.625
The answer is a negative number. Since the base of a trapezium cannot have a negative length, there does not exist a trapezium with the given information.
Answer:

Step-by-step explanation:
Okay what we need to do first is add the whole numbers.
1 1/3 and 2 1/4 and the whole numbers are 1 and 2.
1+2 is 3.
Now to add 1/3 and 1/4, but something is wrong. We need the denominator to be the same.
So we need to find the same denominator.
We need to multiply the denominators by each other.
So the denominators are 3 and 4 of 1/3 and 1/4.
3*4 and 4*3 is both 12.
What you do to the bottom is what you need to the top the numerator.
1*4 is 4 and 1*3 is 3.
4/12 + 3/12.
Since the denominators are the same don't add those together keep them the same.
4/12 + 3/12 = 7/12
Now add the whole number 3 to 7/12
3 7/12 is your answer.
Answer: The speed of the boat in still water is 6.5 mph.
The speed of the current is 2.5 mph
Step-by-step explanation:
Let x represent the speed of the boat in still water.
Let y represent the speed of the current.
A boat going upstream on The River averages 4 mph. Assuming it travelled against the current while going upstream, its total speed would be (x - y) mph. It means that
x - y = 4- - - - - - - - - - - -1
Going downstream, the boat averages 9 mph. Assuming it travelled with the current while going upstream, its total speed would be (x + y) mph. It means that
x + y = 9- - - - - - - - - - - -2
Adding both equations, it becomes
2x = 13
x = 13/2
x = 6.5 mph
Substituting x = 6.5 into equation 1, it becomes
6.5 - y = 4
y = 6.5 - 4
y = 2.5 mph
