Answer:
468 minutes
Step-by-step explanation:
Given data
At a race a few months ago, she finished in 360 minutes
let us find 30% of 360 minutes
=30/100*360
=0.3*360
=108 minutes
Hence she finished with an added time of 108minutes
Therefore, in all she finished in
=108+360
=468 minutes
The product of 23 and a letter
-4 cause a negative plus a negative is a negative
The dimensions of the rectangular plot of land that sits on a riverbank is 32 m by 9 m or 18 m by 16 m.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.
Let x represent the length and y represent the width. Hence:
x + 2y = 50
x = 50 - 2y
Also:
xy = 288
(50 - 2y)y = 288
y = 9; and y = 16
x = 32; and x = 18
The dimensions of the rectangular plot of land that sits on a riverbank is 32 m by 9 m or 18 m by 16 m.
