1 answer:
ehidna [41]3 years ago
4 0

Answer:

Volume = 3.15 cm³

Step-by-step explanation:

mass = 5 gram

density = 1.59 g/cm³

now

density = mass/ volume

or, 1.59 = 5/v

or, v = 5/1.59

so, v = 3.15 cm³

The population of Mathloversville is given by the equation P=38e^0.095t , where t is the number of years from now. How long will
lys-0071 [83]

Answer:

Approximately 107years

Step-by-step explanation:

Given the population of Mathloversville modelled by the equation P=38e^0.095t where t is the number of years from now.

To find the time it will take the population to reach 1million from now, we will substitute P = 1,000,000 into the equation given

1,000,000 = 38e^0.095t

Dividing both sides by 38

1,000,000/38 = e^0.095t

Taking the ln of both sides

ln(1,000,000/38) = ln e^0.095t

ln26,315.79 = 0.095t

10.18 = 0.095t

t = 10.18/0.095

t = 107.16years

It will take approximately 107years for the population to reach 1million

10 mm<br>4 mm<br>u What is the volume of the cone to the nearest whole number?<br>​
BaLLatris [955]

Answer:

V=167.5 cubic mm

Step-by-step explanation:

Volume of the Cone is given with the formula

V=\frac{1}{3} \pi r^2h

though we are not specified what is radius and which one is the height , we are assuming that ,

Height = 10 mm

Radius = 4 mm

Substituting these values in the formula we get

V=\frac{1}{3} \pi 4^2 \times 10

V=\frac{1}{3} \pi 160

V=\frac{160 \times 3.14}{3}

V=\frac{160 \times 3.14}{3}

V=\frac{502.40}{3}

V=167.5

Express the following numbers as a product of their prime factors <br> 24<br> Please show working
Studentka2010 [4]

Answer:

2 x 2 x 2 x 3

Step-by-step explanation:

Find two numbers that multiply together to form 24:

2 x 12 = 24

Find two numbers that multiply together to form 12, a factor of 24. Replace 12 with these numbers:

2 x (2 x 6) = 2 x 12 = 24

Find two numbers that multiply together to form 6, a factor of 12. Replace 6 with these numbers:

2 x (2 x (2 x 3)) = 2 x (2x6) = 2 x 12 = 24

Two and three cannot be factored any further, therefore the prime factors of 24 are 2, 2, 2, and 3.
