A division problem is shown below.

masya89 [10]

4 1/3 : 5 1/6
To divide fractions, you first must find the improper version of each (4 1/3 = 13/3; 5 1/6= 31/6)
Now you have 13/3 : 31/6.
Since to divide fractions, you find the reciprocal of the second number in the equation and multiply it by the first number(the reciprocal is when the numerator and denominator is switched)
Meaning that to solve this you need to multiply 13/3 * 6/31

Meaning that the answer is the first one

Which ordered pair is a solution of the equation?

castortr0y [4]

Answer:

d)

true

Step-by-step explanation:

- x - 4y = - 10

x + 4y - 10 = 0

a)

3 + 4×2 - 10 = 0

3 + 8 - 10 = 0

11 - 10 ≠ 0 (false)

b)

- 3 + 4×3 - 10 = 0

12 - 3 - 10 = 0

12 - 13 ≠ 0 (false)

c)

false

d)

true

The radius of a sphere is increasing at a rate of 3 mm/s. How fast is the volume increasing when the diameter is 60 mm

mina [271]

Answer:

The volume is increasing at a rate of 33929.3 cubic millimeters per second.

Step-by-step explanation:

Volume of a sphere:

The volume of a sphere of radius r is given by:

$V = \frac{4\pi r^3}{3}$

In this question:

We have to derivate V and r implicitly in function of time, so:

$\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}$

The radius of a sphere is increasing at a rate of 3 mm/s.

This means that $\frac{dr}{dt} = 3$

How fast is the volume increasing when the diameter is 60 mm?

Radius is half the diameter, so $r = 30$ . We have to find $\frac{dV}{dt}$ . So

$\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}$

$\frac{dV}{dt} = 4\pi (30)^2(3) = 33929.3$

The volume is increasing at a rate of 33929.3 cubic millimeters per second.
