➡️ 37,680m² will be the curved surface area of the cylindrical tank.

${\purple{\underline{\textsf{\textbf{Explanation : }}}}}$

Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm

We need to find the curved surface area

<u>We know that</u>,

➩ Curves surface area of a cylinder = 2πrh

r (radius) = 30cm.

h (height) = 200cm.

Therefore,

➩ Curves surface area of a cylinder:

➩ 2 × 3.14 × 30 × 200

➩ 2 × 18,840

➩ 37,680 m² ans.

Factories 24x^2-41x+12

andriy [413]

Answer:

(3x - 4)(8x - 3)

Step-by-step explanation:

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 24 × 12 and sum = - 41

The required factors are - 32 and - 9

Use these factors to split the x- term

24x² - 32x - 9x + 12 ( factor the first/second and third/fourth terms )

= 8x(3x - 4) - 3(3x - 4) ← factor out (3x - 4) from each term

= (3x - 4)(8x - 3) ← in factored form

The equation sin(40o) =b/20 can be used to determine the length of line segment AC. What is the length of AC? Round to the neare

boyakko [2]

For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9

John Gray brought a basic car for $8,250.00, with options that cost $324.00. There's a 6% sales tax in his state and a combined

dybincka [34]

Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
      = 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
   = 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
      = 9138.44 dollars
<span>$9,138.44</span> is the correct option in regards to the question given.

An epidemiologist is observing the decay pattern of a pathogenic bacteria after applying a vaccine. He starts with 2,000 bacteri

Viktor [21]

Answer:

Number of bacteria after 36 hour (A) = 381 (Approx)

Step-by-step explanation:

Given:

Number of bacteria (p) = 2,000

Total time (n) = 36 hours

Decay rate = 4.5 % = 0.045 per hour

Find:

Number of bacteria after 36 hour (A)

Computation:

$A=p(1-r)^n$

Number of bacteria after 36 hour (A) = 2,000[1-0.045]³⁶

Number of bacteria after 36 hour (A) = 2,000[0.955]³⁶

Number of bacteria after 36 hour (A) = 2,000[0.190599333]

Number of bacteria after 36 hour (A) = 381.19866

Number of bacteria after 36 hour (A) = 381 (Approx)
