Answer:
93 pieces
Step-by-step explanation:
To cover his backyard with sod, he needs to cover the area of the backyard.
His backyard is a rectangle, and area of a rectangle is given as:
Where,
is the length, and
is the width
So, the area of Jim's backyard is square yards.
The area of each sods are solved using the area of the rectangle formula. So we have square yards as the area of each sod.
To find HOW MANY of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:
Since, fractional sods can't be bought, Jim has to buy 93 sods to cover his backyard.

Answer:
For an equation like:
y = a*x + b
a is the slope, and this is the rate of change of the function.
For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.
Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.
Answer:
The height of each step is 1957 yards
Step-by-step explanation:
we are given
Tristan is building steps up to a deck that is 15656 yards above the ground
so, total height =15656 yards
Number of steps =8
now, we can use formula
Height of each step = ( total height)/( number of steps)
now, we can plug these values
and we get
Height of each step is
