insurance with her remaining savings?
Answer:
3 full years
Step-by-step explanation:
First figure how much she has left over.
15,000-12700=2300
Each year insurance costs $600.
$2300/600 = 3.8
She almost has 4 years but can't quite pay the 4th year so the answer is 3 years.
Answer:
81 π
Step-by-step explanation:
The total central angle for a circle is 360 degrees.
In the question the sector with angle 120 degrees has area 27π.
So the circle can be considered as a combination of 3 sectors having angle 120 degrees each. Refer to the figure below.
Thus area of the circle will be three times of the area of the sector.
Area = 3 × 27π = 81π
Answer:
Step-by-step explanation:
81pi
A gardener is building a flower garden with a border of mulch around it. A model of the design is shown.
A large rectangle with dimensions of 10.5 feet by 16 feet. A smaller rectangle with dimensions of 5.5 feet by 8 feet inside of the larger one.
Part A: Find the area of the mulch border that surrounds the 5.5 ft by 8 ft flower garden. Show all work.
Part B: If the mulch cost $3.64 per sq ft, how much will the mulch for this project cost? Show all work.
Answer:
Part A:
To find the area of the mulch border, we need to subtract the area of the smaller rectangle (flower garden) from the area of the larger rectangle.
The area of the larger rectangle is given by:
Area = length * width = 10.5 ft * 16 ft = 168 sq ft
The area of the smaller rectangle (flower garden) is given by:
Area = length * width = 5.5 ft * 8 ft = 44 sq ft
Therefore, the area of the mulch border is:
Area of mulch border = Area of larger rectangle - Area of smaller rectangle
Area of mulch border = 168 sq ft - 44 sq ft = 124 sq ft
Part B:
To find the cost of the mulch for this project, we need to multiply the area of the mulch border by the cost per square foot.
Cost of mulch = Area of mulch border * Cost per sq ft
Cost of mulch = 124 sq ft * $3.64/sq ft
Multiplying the values gives:
Cost of mulch = $451.36
Therefore, the mulch for this project will cost $451.36.
