Answer:
A = l * w. We can substitute the expressions for length and width into the equation for area ... values in the formula for perimeter, we will get. P = 2l + 2w. P = 2(5)+2(3) P = 10+6 ... L = 18 cm. B = 7 cm. Perimeter of rectangle = 2(length + breadth) P = 2 (L + B) ... Total time taken = Total distance walked × time taken to walk 1m.
Answer:
1.6 hours
Step-by-step explanation:
Number of opening hours a day = 8
Number of groups = 5
Dividing the number of opening. Hours equally among the 5 groups :
8 hours / 5
= 1.6 hours per group per day
The direct variation between x and y may be written as,
y = kx
where k is the constant of variation. From the first set of values of the variables,
12 = k(8)
the value of k is 1.5. Substituting the next set to the same equation,
y = 1.5(14)
The value of y is 21.
