A Japanese garden has a circular koi pond in the middle that has a radius of 3 feet. A rectangle with length of 16 feet and widt

Mariulka [41]

Answer:

first, find the area of the circle cut.

r= 3 feet

π=3.14

area of a circle= πr²= 3.14×3×3= 28.26 sq.feet

Now, find the area of the rectangle and subtract it by the area of the circle.

area of rectangle = l×b

length of the rectangle= 16 feet

breadth/width of the rectangular garden= 14 feet

area= 16×14= 224 sq. feet

now, area of the garden surrounding the koi pond= 224-28.26

=195.74 sq. feet

Three red rods are 2cm longer than two blue rods. Three blue rods are 2cm longer than four red rods. How long is each rod?

nydimaria [60]

Answer:

The length of each red rod is 10 cm and the length of each blue rod is 14 cm

Step-by-step explanation:

Let

x ----> the length of each red rod in centimeters

y ----> the length of each blue rod in centimeters

we know that

$3x=2y+2$ ----> equation A

$3y=4x+2$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (10,14)

see the attached figure

therefore

The length of each red rod is 10 cm and the length of each blue rod is 14 cm

natali 33 [55]

Answer: 0.4207

Step-by-step explanation:

Let $\overline{x}$ be the sample mean area.

Given: Population mean : $\mu=250$ sq. feet

Standard deviation: $\sigma=2$ sq. feet

Sample size : n= 10

The probability that the sample mean area is $249.6 \text{ ft}^2$ or less if the manufacturer’s claim is true.

$P(\overline{x}$

Required probability = 0.4207
