Find the area of the circle below

Answer:

1

Step-by-step explanation:

⅓Log₁₀(125/8) – 2Log₁₀(2/5) + Log₁₀(80/125)

The above expression can be simplified as follow:

⅓Log(125/8) – 2Log(2/5) + Log(80/125)

Recall:

a LogM = Log Mᵃ

Therefore,

⅓Log(125/8) – 2Log(2/5) + Log(80/125)

= Log(125/8)¹/³ – Log(2/5)² + Log(80/125)

= Log(5/2) – Log(4/25) + Log(16/25)

Recall:

Log M – Log N = Log M/N

Log(5/2) – Log(4/25) = Log (5/2 ÷ 4/25)

Log(5/2) – Log(4/25) = Log (5/2 × 25/4)

Log(5/2) – Log(4/25) = Log (125/8)

Therefore,

Log(5/2) – Log(4/25) + Log(16/25)

= Log (125/8) + Log(16/25)

Recall:

Log M + Log N = Log MN

Log (125/8) + Log(16/25)

= Log (125/8 × 16/25)

= Log 10

= Log₁₀10 = 1

Therefore,

⅓Log(125/8) – 2Log(2/5) + Log(80/125)

= 1

Answer:

This is the math riddle for pi..

Step-by-step explanation:

They mean by this question,  What do you get if you divide the circumference of a pumpkin pie by its diameter?

Pi is the ratio of circumference and the diameter.  and people want to understand why pi =3.14. ... very long explanation. This will be college level to understand these math.

We don’t really need the diagram at this stage of course.

The internal angle is  180o−360o / 24=180o−15o =1 65o . Half of this is  82.5o . The perimeter is now  24x  so we have:

24 x /h  = 24 / tan(82.5o) Rather remarkably:

So tan(82.5o) =√+2 + √+3+√+4+√+6

24 x / h = 24    / ( √+2 + √+3+√+4+√+6 ≈3 .1596599421

Step-by-step explanation:

Use the slope formula (rise/run):

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

(375 - 150)/(5-2) = 225/3 = 75

Answer:

D) 500 square feet

Step-by-step explanation:

20x40=800

30x10=300

800-300=500

Answer:

500 square feet

Step-by-step explanation:

Walk way A=bh

A=40 times 20

A=800

garden

A=30 times 10

A=300

Now subtract walkway from the garden. 800 - 300= 500

Answer:

150 trees

Step-by-step explanation:

If 40% of the trees is 300, you'd expect that 20% (half the percentage) is also half the trees.

Answer:

150 trees

Step-by-step explanation:

40 % / 2 = 20%

300 / 2 = 150 trees

Answer:

it is B

Step-by-step explanation:

Answer: B)  4 & 1/6

Nice work on getting the correct answer.

============================================================

Explanation:

x is opposite the marked acute angle

5 is opposite the corresponding acute angle

So x and 5 are proportional to each other. We can form the ratio x/5

Similarly, 10 and 12 are proportional to one another. We can form the ratio 10/12.

Set those ratios equal to each other and solve for x

x/5 = 10/12

12x = 5*10 ... cross multiply

12x = 50

x = 50/12 ...... divide both sides by 12

x = (25*2)/(6*2)

x = 25/6

x = (24+1)/6

x = 24/6 + 1/6

x = 4 + 1/6

x = 4 & 1/6 which shows why choice B is the answer.

Side note: 25/6 = 4.167 approximately

Answer:

[tex]Probability = \frac{1}{11}[/tex]

Step-by-step explanation:

Given

Marbles = 12

Selection without replacement

Required

Determine the probability of selecting 2 primes

Between 1 and 12, the prime digits is 4, and they are: 3, 5, 7 and 11

So, when the first marble is picked, the probability that it will be prime is:

[tex]P(First) = \frac{4}{12}[/tex]

Now there are 3 primes left and 11 marbles in total. So, the probability of selecting another prime is:

[tex]P(Second) = \frac{3}{11}[/tex]

The required probability is:

[tex]Probability = P(First) * P(Second)[/tex]

[tex]Probability = \frac{4}{12} * \frac{3}{11}[/tex]

[tex]Probability = \frac{1}{11}[/tex]

Answer:

a [tex]A = 30 + 0.45 n[/tex]

b [tex]A = 90.3[/tex]

c 0 customers

Step-by-step explanation:

Given

[tex]Base\ Amount = 30[/tex]

[tex]Rate = 0.45[/tex] per customer

Solving (a): Amount (A) on n customers

This is calculated as:

[tex]A = Base\ Amount + Rate * n[/tex]

[tex]A = 30 + 0.45 * n[/tex]

[tex]A = 30 + 0.45 n[/tex]

Solving (b): Amount on 134 customers

In this case: n = 134

So:

[tex]A = 30 + 0.45 * 134[/tex]

[tex]A = 30 + 60.3[/tex]

[tex]A = 90.3[/tex]

Solving (c): Customers at noon.

At noon, the amount is 30.

So:

[tex]A = 30 + 0.45 n[/tex]

[tex]30 = 30 + 0.45n[/tex]

Collect like terms

[tex]0.45n = 30 - 30[/tex]

[tex]0.45n =0[/tex]

[tex]n = 0[/tex]

Answer:

Monday hours        +    Thursday hours         =      Total hours

            1 1/2                 +        2 3/4                   =       3 +    (? how do you add 1/2+3/4)

 Now, you could convert to all improper fractions:

               3/2                 +        11/4

               6/4                 +         11/4               [4 is the Least Common Multiple of 2 and 4]

                           17/4

                           4 1/4                                   [then back to mixed numbers]

 Or. you could add 1+2=3

     and    1/2  +  3/4

              2/4   +  3/4

                    5/4

                 1 1/4        [convert to mixed number]

         3 + 1 1/4  = 4 1/4        [remember to add the 3]
