No solution simply because the expression cannot be solved with rational numbers
B and E are the correct answers, as 2/100 is the same thing as 0.02.
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
Answer - Width 23
Length - 26
W = Width
L + 3 = Length
Perimeter = 2L = 2W
98 = 2(W + 3) + 2W
98 = 2W + 6 + 2W
98 = 4W + 6
92 = 4W
W = 92/4
W = 23
Width is 23 inches
Length is 3 more -- 23 + 3 = 26
We can double check our work:
26 + 26 + 23 + 23 = 98 Inches

To answer this item, we have 4 as the speed of the kayaker in still water and the speed of current be y.
When the karayaker moves upstream or against the current, his speed would be 4 - y. Further, if he moves downstream or with the current, the total speed would be 4 + y. The time utilized for the travel is equal to the ratio of the distance and the speed.
Total time = 9/(4 - y) + 9/(4 + y) = 6
We multiply the equation by (4-y)(4+y)
9(4-y) + 9(4 + y) = 6(4-y)(4+y)
Simplifying,
72 = 96 - 6y²
Transposing all the constants to only one side of the equation and rearranging,
6y² = 96 - 72
y² = 4
y = 2
Hence, the speed of the river's current is 2 miles/hr. <em>The answer is letter B.) 2 miles/hour.</em>
