Answer:
Savings = 
- 
dollars.
Step-by-step explanation:
We are given that,
Juanita usually buys 50 pounds of mulch for $6.99.
That is, total cost of 254.7 pounds of mulch = dollars.
Now, since there is sale on the price of the mulch, we have,
Price of 50 pounds of mulch on sale = $5.99
Then, price of 254.7 pounds of mulch on sale = dollars.
Thus, the savings Juanita had = Original price of 254.7 pounds of mulch - Price of 254.7 pounds of mulch on sale.
Hence, savings = - dollars.
18+18=36. 20% is 9 apples. 36+9=45. 45 apples at the stand. (not good for business)
$3.75/6 ounces
= 0.625 unit price
QUESTION 12
The given figure has five unequal sides.
The perimeter is the distance around the figure.
So we add all the lengths of the sides of the rectangle to get,
We regroup the like terms to obtain,
This will simplify to give us,
QUESTION 13
The given figure has two pairs of sides that are equal in length and three unequal sides.
The perimeter can be found by adding all the lengths of the sides of the of the figure.
This will give us
We regroup like terms to obtain,
This finally simplifies to ,
.
QUESTION 14
This plane figure has four sides that are equal to 4j and two sides that are equal to 2h.
We add all the lengths of the sides of the plane figure to get,
This will simplify to give us,
Answer:
5) Part A: The rate of change, also known as the slope, is the "0.6x" part of the equation. It means that for every week the puppy is alive, x, that number is multiplied by 0.6 pounds.
Part B: The y-intercept is 4 pounds, which represents a puppy being 4 pounds at birth.
Part C: y = 0.6x + 4
y = 0.6(8)+4
y = 8.8
At 8 weeks, a puppy is estimated to be 8.8 pounds.
Part D: y = 0.6x + 4
22 = 0.6 + 4
-4 -4
18 = 0.6x
18/0.6 = 0.6x/0.6
30 = x
It would take a puppy 30 weeks to reach 22 pounds.
