Answer:
D. 18 bags
Step-by-step explanation:
Given:
Matilda is filling a circular section of her porch with colorful pebbles.
Diameter of circular section = 15 feet.
Each bag of pebbles covers 10 square feet.
Question asked:
How many bags of pebbles will Matilda need?
Solution:
Diameter of circular section = 15 feet
Radius, r =
10 square feet is covered by number of bag of pebbles = 1
1 square feet is covered by number of bag of pebbles =
176.78 square feet is covered by number of bags of pebbles =
We found up to 17 bags of pebbles there is still some place left to fill the section:-
Thus, Matilda need about 18 bags of pebbles to fill the circular section of her porch.

Answer:
The total cost for 1.5 pounds of apples is $5.25
Step-by-step explanation:
To find the total cost using partial products, you can do the following:
Calculate the cost for 1 pound of apples, which is $3.50.
Since Zoe bought 1.5 pounds of apples, you can use partial products to find the total cost:
First, calculate the cost for 1 pound: $3.50.
Next, calculate the cost for 0.5 pounds (half of 1 pound), which is half of $3.50: $3.50 / 2 = $1.75.
Finally, add the cost for 1 pound and 0.5 pounds to find the total price: $3.50 + $1.75 = $5.25.
So, the total cost for 1.5 pounds of apples is $5.25.
y = - 25
since x varies directly with y then we can express the relationship as
x = ky ← k is the constant of variation
to find k use the given condition y = - 10 when x = 4
k = = = -
hence x = - y
when x = 10
10 = - y
multiply both sides by - 5 and divide both sides by 2 )
- 50 = 2y ⇒ y = - 25
