The combined ages of a dog and his owner are 96 years in total. The owner is 3 times older than his dog. How old is the owner?

nikitadnepr [17]

Answer:

72 yrs old.

Step-by-step explanation:

The combined age

D+O=96

The owner is 3 times older than dog

O=3D

D+3D=96

4D = 96

D= 24

Now substitute the value of D in O=3D

O=3.24= 72

The owner is 72 years old.

The figure is made up of a hemisphere and a cylinder.

Sidana [21]

Answer:

90π in^3.

Step-by-step explanation:

Total Volume = volume of cylinder + volume of the hemisphere.

= πr^2h + 1/2*4/3πr^3

= π * 3^2 * 8 + 2/3 π 3^3 ( Note the radius r = 1/2 diameter = 1/2*6 = 3)

= 72π + 18π

= 90π in^3.

Helllllllllppppppppp

Olin [163]

Answer:

$\frac{8}{5} x^{2} - \frac{16}{5} xy + 4x$

$xy^{2} + \frac{2}{3}y - 8y^{2}z$

Step-by-step explanation:

We have to simplify the followings:

1) $- \frac{4}{5}x (- 2x + 4y - 5)$

= $- \frac{4}{5}x \times (- 2x) + - \frac{4}{5}x \times (4y) + - \frac{4}{5}x \times (- 5)$

{By distributive property of multiplication}

= $\frac{8}{5} x^{2} - \frac{16}{5} xy + 4x$ (Answer)

2) $2y^{2}( \frac{1}{2} x + \frac{2}{6}y - 4z)$

= $2y^{2} \times (\frac{1}{2} x) + 2y^{2} \times ( \frac{2}{6}y) - 2y^{2} \times (4z)$

{By distributive property of multiplication}

= $xy^{2} + \frac{2}{3}y - 8y^{2}z$ (Answer)
