Answer:

The answer is 8.5

Step-by-step explanation:

The nearest tenth of a number is the first decimal. As can be seen, 8.54 has two decimals, so we must round the first one. If the second decimal was 5 or bigger than 5, then the first decimal would be increased by 1, and 8.54 would be rounded to 8.6. However, the second decimal is smaller than 4, so the first decimal remains the same, and 8.54 is rounded to 8.5.

Hope this help

Have a nice day!!!!

Solving each system by Eliminating x-y-2z=4 -x+2y+z=1 -x+y-3z=11

elena-s [515]

Answer:

x = 0

y = 2

z = -3

Step-by-step explanation:

x-y-2z=4 (1)

-x+2y+z=1 (2)

-x+y-3z=11 (3)

(1) + (3) = x-y-2z + (-x)+y-3z = 4+11

= -5z = 15

-> z = -3

(1) + (2) = x - y - 2z + (-x) + 2y + z = 4+1

= y-z = 5

= y- (-3) = 5

-> y = 2

(1) = x-y-2z = 4

= x - 2 - 2 * (-3) = 4

-> x = 0

The solid shape is a cone and a half sphere. So the equation would be (cone volume) + (1/2 sphere volume):
$cone = \frac{1}{3} \pi {r}^{2} h \\ sphere = \frac{4}{3} \pi {r}^{3} \\ object = ( \frac{1}{3} \pi {r}^{2} h) + \frac{1}{2} ( \frac{4}{3} \pi {r}^{3} )$
If the volume of the cone is 270pi and the height of the cone is 10, then:
$270\pi = \frac{1}{3} \pi {r}^{2} (10) \\ 27 = \frac{1}{3} {r}^{2} \\ 80 = {r}^{2} \\ r = 9$
The radius of the object is 9 cm. Therefore, we can plug into the formula for the total volume:
$object = 270\pi + \frac{1}{2} ( \frac{4}{3} \pi {(9)}^{3} ) \\ = 270\pi + \frac{2}{3} (729\pi) \\ = 270\pi \: + 243\pi \\ = 513\pi$
The total volume is 513 pi cm^3
