<span>To solve this problem, we can use this formula d = rd (distance = rates x time)
She runs at a speed of 9 mph and walks at a speed of 3 mph.
Her distance running is
d = 9tr
where tr is the time she spends running
Her distance walking is
d = 3tw
where tw is the time she spends walking
The distances are the same so
9tr = 3tw
We also know that the total time is 5 hours
tr + tw = 5
tr = 5-tw
Substitute this value of tr in the first equation
9tr = 3tw
9(5-tw) = 3tw
45-9tw = 3tw
45 = 12tw
3.75= tw
Denise will spend 3.75 hours (3 hours, 45 minutes) walking back and 1.25 hours (1 hour, 15 minutes) running.</span>
Answer:
gallon

A gallon is a measuring unit used to measure the liquid capacity. It helps in measuring the volume and capacity of a fluid. The capacity of one gallon is equivalent to 3.79 liters. It is used to denote the measurement of approximately four liters of liquid.
Mrs. Larivierre had filled a tub with water. To measure the water content of the tub, the most appropriate unit would be a gallon.
-9 -4 = -13
-4 - 3 = -7
vector is <-13, -7>
We are given
Jim's backyard:
Length is
width is
Since, this is rectangle
so, we can find area of rectangle
Area of one sod:
length is
width is
Since, it is rectangle in shape
so,
Number of pieces of sod:
we can use formula
Number of pieces of sod = (area of Jim's backyard)/(area of one sod)
now, we can simplify it
pieces need ..............Answer
