Answer:
The perimeter of the rectangle is 93.4m
Step-by-step explanation:
F
irst of all we have to calculate the width, for this we will use the area formula of a rectangle
a = area = 159.1m²
l = length = 3.7m
w = width
a = l * w
w = a / l
we replace the known values
w = 159.1m² / 3.7m
w = 43m
Now we use the formula to calculate perimeter of a rectangle
p = perimeter
w = width = 43m
l = length = 3.7m
p = 2w + lw
p = 2 * 43m + 2 * 3,7m
p = 86m + 7.4m
p = 93.4m
The perimeter of the rectangle is 93.4m
Answer:
c
Step-by-step explanation:
Its c because 10/3.69=0.369 then you tomes that by twelve and itequals 4.428 round that up and its 4.43.
If we need sections that are 18 ft. long from available 78 ft. long line than we will divide 78/18 =4.(3)
So we will get 4 sections that are 18 ft. long and we will have a remainder of 6 ft line not used.
Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
Answer:
y
x
