A cone has a volume of 47.1 cm³ and a radius of 3 cm what is its height?

Answers

Radius of cone ( r ) = 3 cm,

Curved surface area of a cone= 47.1 cm²

Curved surface area of a cone= πrl

47.1 = πrl

47.1 = 3.14 × 3 × l

l = 47.1 / (3.14 × 3)

l = 15.7 / 3.14= 1570/314= 5 cm

slant height (l) = 5 cm

Height of a cone (h) = √(l²) - (r²)

h = √ 5² -3²

h = √ 25 - 9 = √ 16 = 4 cm

h = 4 cm

Volume of cone= ⅓(πr²h)

= ⅓(3.14 × 3 × 3 × 4)

= 3.14 × 12= 37.68 cm³

Hence, the volume of a cone is 37.68 cm³.

It took Hank 3.4 hours to travel 124 miles. At that rate, how long will it take Hank to travel 310 miles?

Answers

Answer: Time = 8.5 hours

Step-by-step explanation:

Step 1

Speed = distance / time

Distance  traveled by  Hank = 124 miles

Time = 3.4 hrs

Speed= Distance / Time

= 124/ 3.4 = 36.47 miles per hour

Step 2

At this same rate of speed =36.47 miles per hour, if he travels 310 miles, he will spend=

Time = Distance / Speed

Time = 310/ 36.47

Time =8.5 hours

Solve for n:
1-5|n-9|=-74

I need answer by 12:10, please help!!!

Answers

Answer:

[tex]n=-6, 24[/tex]

Step-by-step explanation:

We are given:

[tex]1-5|n-9|=-74[/tex]

Subtract 1 from both sides:

[tex]-5|n-9|=-75[/tex]

Divide both sides by -5:

[tex]|n-9|=15[/tex]

By definition of absolute value:

[tex](n-9)=15\text{ or } -(n-9)=15[/tex]

Solve for each case:

[tex]n=24\text{ or } n=-15+9=-6[/tex]

Therefore, our two solutions are:

Write the linear equation in slope-intercept form given the following:
(-3, 7) and (6, -8)

Answers

Answer:

y = - [tex]\frac{5}{3}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 3, 7) and (x₂, y₂ ) = (6, - 8)

m = [tex]\frac{-8-7}{6+3}[/tex] = [tex]\frac{-15}{9}[/tex] = - [tex]\frac{5}{3}[/tex] , then

y = - [tex]\frac{5}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (6, - 8) , then

- 8 = - 10 + c ⇒ c = - 8 + 10 = 2

y = - [tex]\frac{5}{3}[/tex] x + 2 ← equation of line

Radium-226 has a half-life of 1660 years. How many years does it take a radium sample to decay to 55% of the original amount? Round your answer to the nearest year.

Answers

Answer:

1432 years

Step-by-step explanation:

A(t) = I(0.5)^t/t1/2

Where t1/2 = half life = 1660

Final amount, A(t) = 0.55 of its original amount =. 0.55I

Hence, we have

0.55I = I(0.5)^t/1660

Take the log of both sides

Log(0.55) = log(0.5)^t/1660

t/1660 = log(0.55) / log(0.5)

t/1660 = 0.8624964

t = 0.8624964 * 1660

t = 1431.7441

t = 1432(nearest whole number)
