Answer:
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
The correct representation of data on x-axis and y-axis is:
x-axis: minutes in increments of 5; y-axis: temperature in increments of 5
Step-by-step explanation:
The minutes will be plotted along the x-axis with increment of 5 minutes because the minutes represents here the independent variable
and the temperature will be plotted along the y-axis with the increment of 5 degrees Celsius because the temperature denotes the dependent variable.
Step-by-step explanation:
i) x (x+2)(3x)
ii) 3x^3+6x^2
iii) (x^2+2x) +(3x^2+6x) +(3x^2)
iv)7x^2+8x
Answer:
a) 17.88 m/s
b) 12.34 m/s
Step-by-step explanation:
Given:
Total time time taken to reach the cottage = 4 hours and 28 minutes
or
= 4 × 60 + 28 = 268 minutes
= 268 × 60 = 16080 seconds
Total distance covered = 178.7 miles
also,
1 miles = 1.609344 km
thus,
178.7 miles = 178.7 × 1.609344 km = 287.5897728 Km
also,
1 Km = 1000 m
287.5897728 Km = 287.5897728 × 1000 = 287589.7728 m
Total displacement = 123.3 miles = 123.3 × 1.609344 km = 198432.1152 m
Now,
a) Speed =
or
Speed =
or
Speed = 17.88 m/s
b) Velocity =
or
Velocity =
or
Velocity = 12.34 m/s
Answer:
2 1/2
Step-by-step explanation:
- 5/8 / 1/4
- 5/8 x 4/1
- cross cancel 4 and 8 to get 5/2 x 1/1
- answer 5/2 or 2 1/2
