Answer:

1 : 6

Step-by-step explanation:

From the question given above, the following data were obtained:

Radius (r) = 10 cm

Height (h) = 15 cm

Ratio of TSA and CSA =?

Next, we shall determine the total surface area (TSA) of the cylinder. This can be obtained as follow:

Radius (r) = 10 cm

Height (h) = 15 cm

Pi (π) = 3.14

Total surface area (TSA) of the cylinder =?

TSA = 2πr(r + H)

TSA = 2 × 3.14 × (10 + 15)

TSA = 6.28 × 25

TSA = 157 cm²

Next, we shall determine the curve surface area (CSA) of the cylinder. This can be obtained as follow:

Radius (r) = 10 cm

Height (h) = 15 cm

Pi (π) = 3.14

Curve surface area (CSA) of cylinder =?

CSA = 2πrh

CSA = 2 × 3.14 × 10 × 15

CSA = 942 cm²

Finally, we shall determine the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder. This can be obtained as follow:

TSA = 157 cm²

CSA = 942 cm²

Ratio of TSA and CSA =?

TSA : CSA = 157 / 942

TSA : CSA = 1 / 6

TSA : CSA = 1 : 6

Thus, the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder is 1 : 6

74% of 19 year old males are atleast 172 pounds , what percent of the males are not atleast 172 pounds?

Answers

Answer:

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

Step-by-step explanation:

Step(i):-

Given that 74% of 19 -year -old males are at least 172 pounds

Let 'X' be a random variable in a binomial distribution

P( X≥172) = 74% = 0.74

we have to find that the percentage of males are not at least 172 pounds

Step(ii):-

The probability of males are not at least 172 pounds

P(X⁻≥172) = 1- P( X≥172)

                 = 1- 0.74

                 = 0.26

Final answer:-

The percentage of males are not at least 172 pounds

P(X⁻ ≥ 172) = 0.26

A pipe can fill a tank in 3 hours. A second pipe can fill the tank in 5 hours.
How long will it take to fill the tank with both pipes running at the same time?

Answers

Answer:

15 hours

Step-by-step explanation:

3: 3, 6, 9, 12, 15

5: 5, 10, 15, 20

15 is the lcm of 3 and 5

Answer:

15 hrs

Step-by-step explanation:

Time for One pipe = 3 hrs

Amount of tank it can fill in 1 hr = 1/3

Time for Second  pipe = 5 hrs

Amount of tank it can fill in 1 hr = 1/5

Tank they can fill together in 1 hr = 1/3 x 1/5= 1/15

Time it takes to fill full tank = 15/1

question: solve the solution using substitution.

Answers

Answer:

x = -3

y = -8

Step-by-step explanation:

2y = x - 13

3x = y - 1;  let y = 3x + 1

substitute to solve for 'x':

2(3x + 1) = x - 13

6x + 2 = x - 13

5x + 2 = -13

5x = -15

x = -3

solve for 'y':

3(-3) = y - 1

-9 = y - 1

-8 = y

Answer:

(-3,-8)

Step-by-step explanation:

Get one of the variables by themself.

3x = y-1

y = 3x+1

Plug that equation into the other one

2(3x+1) = x-13

Distribute the 2 to 3x+1

6x+2 = x-13

Combine like terms

6x+2 = x-13

-x       -x

5x+2 = x-13

    -2        -2

5x = -15

Divide by 5 on both sides

5x = -15

÷5   ÷5

x = -3

Find y

3(-3) = y-1

-9 = y-1

+1       +1

y = -8

Step-by-step explanation:

a) 3(x squared plus 3x cubed - 2)​

x squared = x²

3x cubed = 3x³

3(x squared plus 3x cubed - 2)​

= 3(x² + 3x³ - 2)

= 3x² + 9x³ - 6

Rearrange according to power

= 9x³ + 3x² - 6

When the expression is divided by 3, it is equivalent to

Answer:

x ≈ 7.7

Step-by-step explanation:

Using Pythagoras' identity on the right triangle on the right side

let the third side be y , then

y² + 4² = 10²

y² + 16 = 100 ( subtract 16 from both sides )

y² = 84

Using Pythagoras' identity on the right triangle on the left side

x² + 5² = y²

x² + 25 = 84 ( subtract 25 from both sides )

x² = 59 ( take the square root of both sides )

x = [tex]\sqrt{59}[/tex] ≈ 7.7 ( to the nearest tenth )
