The landscaping project you are working on has a circular flower garden 18 feet in diameter. To determine the number of plants t

o put in the garden, you need to calculate the area. What is the approximate area of the flower garden in square feet?
Mathematics

Answer:

The approximate area of the flower garden is 254.34\ ft^{2}

Step-by-step explanation:

we know that

The area of the circle ( circular flower garden) is equal to

A=\pi r^{2}

we have

r=18/2=9\ ft ----> the radius is half the diameter

substitute

A=\pi (9^{2})=81\pi\ ft^{2} ----> exact value of the area

Find the approximate value of the area

81(3.14)=254.34\ ft^{2}

What is the equation of the line that passes through the point (- 1, 5) and is parallel to the line y = - 3x + 5
Harlamova29_29 [7]

Answer:

<h2>          y - 5 = -3(x + 1)</h2>

Step-by-step explanation:

Parallel lines has the same slope.

The equation of a line that passing through point (x₁, y₁) with a slope of m is:

y - y₁ = m(x - x₁)

m = -3

(-1, 5)   ⇒  x₁ = -1,  y₁ = 5

Therefore the equation:

y - 5 = -3(x + 1)

Find the GCF of numbers 132 and 242 using prime factorization.
tatyana61 [14]

Answer:

1)Find the prime factorization of 242

242 = 2 × 11 × 11Step-by-step explanation:

2)Find the prime factorization of 132

132 = 2 × 2 × 3 × 11

3)To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 11

The lost one 4) GCF = 22

34,258 and 47,163 <br> The value of 4 in------ is ----- times<br> The value of 4 in -------
Mariulka [41]
The value of 4 in 47,163 is 10 times greater than the value of 4 in 34,258.

Each time you move one place over (e.g. tens to hundreds) the number gets 10 times larger if you move to the left and 10 times smaller if you move to the right. So, for example you go from tens to hundreds it is 10 times larger, but if you go from hundreds to tens then it is 10 times smaller.

In a continuous series, mean(x) = 80, assumed mean(A) = 60 and<br>EF=40 then find the value of EFd.​
Aneli [31]

Using the given information, the value of Σfd is 800

<h3>Calculating mean using Assumed mean </h3>

From the question, we are to determine the value of Σfd

The formula for mean, using the assumed mean method is given by

\bar x = A + \frac{\sum fd}{\sum f}

Where \bar x is the mean

A is the assumed mean

From the given information,

\bar x = 80

A = 60

\sum f = 40

Putting the parameters into the equation, we get

80 = 60 + \frac{\sum fd}{40}

80-60 = \frac{\sum fd}{40}

20 = \frac{\sum fd}{40}

\sum fd = 20 \times 40

\sum fd = 800

Hence, the value of Σfd is 800
