Find the multiplicative inverse of 2/3 * - 5/7​

Mathematics
1 answer:
boyakko [2]3 years ago
6 0

Answer:

-\frac{21}{10}   is the required multiplicative inverse.

Step-by-step explanation:

First of all simplify the given expression.

\frac{2}{3}\cdot \frac{-5}{7}=-\frac{2\cdot \:5}{3\cdot \:7}=-\frac{10}{21}

Multiplicative inverse of any number when multiplied gives 1.

The multiplicative inverse of  -\frac{10}{21}  is -\frac{21}{10}  because:

-\frac{10}{21}\times -\frac{21}{10}=1

Best Regards!

Answer:

The volume of this cylinder is 9184.5 cubic feet.

Step-by-step explanation:

The area of a circle is \pi r^2 and the volume of a cylinder with that base is just that area times the height:

V=\pi r^2\times h

Here, we're given the diameter, but we need the radius. The radius of a circle is just half of the diameter:

r=30\times0.5=15

Next, you can use that radius to calculate the area of the base:

A=3.14\times15^2\\A=3.14\times225\\A=706.5

Finally, multiply that by the height to find the volume of the cylinder:

V=706.5\times13\\V=9184.5

The volume of this cylinder is 9184.5 cubic feet.
