Answer: Question 1
a)5.47
b)4.53
Step-by-step explanation:
Answer: plants are same height in 30 days; Plant A is tallest in 6 weeks
Step-by-step explanation:
x = number of days
4 + (2/3)x = 9 + (1/2)x
(2/3)x - (1/2)x = 9 - 4
(1/6)x = 5
x = 30, number of days for Plant A and Plant B to be same height.
6 wks = 42 days
Plant A in 42 days: 4 + (2/3)(42) = 32 inches
Plant B in 42 days: 9 + (1/2)(42) = 30 inches
Answer:
Width = 30
Step-by-step explanation:
Area = 18x * 10y = 180xy
Length = 6xy
Width = ?
Since the shape of the office complex is a rectangle,
Area of a rectangle = length × width
180xy = 6xy × width
Width = 180xy / 6xy
Width = 30
4*200+4*70+4*5, or you can just use a calculator.
