Part A:
First, we will need to compute the area of the lawn.
We are given that the lawn is a rectangular plot with dimensions 60 ft and 90 ft.
Area of rectangle = length * width
Area of lawn = 60 * 90 = 5400 ft^2
Now, we will compute the number of ounces.
We are given that:
<span>Each ounce of grass seed will cover 120 square feet. Therefore, to know the number of ounces needed to cover 5400 square feet, all we have to do is cross multiplication as follows:
1 ounce ---------> 120 square feet
?? ounce --------> 5400 square feet
Number of ounces needed = (5400*1) / (120) = 45 ounces
Part B:
We know that one ounce is equivalent to 0.0625 pounds.
For the lawn, we need 45 ounces, this means that:
number of pounds needed for the lawn = (45*0.0625) / (1) = 2.8125 pounds
which is approximately 3 pounds.
We know that each bag weighs one pound, therefore:
number of bags needed = 3 bags
Hope this helps :)

Answer:
$13
Step-by-step explanation:
First, find how much she put into the bank:
84 - 45 = $39
Then, multiply this by 2 to find how much she made, because this was half of the money she got:
39(2) = 78
Then, divide this by 6 to find how much she makes a day:
78/6 = 13
= $13
Answer:
56w+79
Step-by-step explanation:
Given the operation (134w+56)−(78w−23), the result of the operation can be gotten as shown below;
(134w+56)−(78w−23)
= 134w+56−78w+23)
= 134w-78w+56+23
= 56w+79
The equivalent operation is 56w+79
Answer:
===========================================================
Explanation:
We start with y = 1/x
Vertically stretching it by a factor of 4 gets us to y = 4/x. Simply multiply the right hand side by 4.
Then reflecting over the y axis means we replace every x with -x to get y = 4/(-x) but that simplifies to y = -4/x. So we can see that any y axis reflection is identical to an x axis reflection, and vice versa. This is due to the symmetry of hyperbolas like this.
Next, we replace x with (x+5) so that we shift the xy axis 5 units to the right, giving the illusion the curve shifts 5 units to the left.
Lastly, we tack on a +4 to shift the graph up 4 units.
The final result is
