V = 1/3 B * H where B is the area of the base and H is the height

to find the base , we find the area

B = s^2 where s is the side length

V = 1/3 s^2 *H

V = 1/3 * 11^2 * 12

V = 1/3 * 121 * 12

V = 484 cm^3

Choice B

The human body has a normal temperature of 98.6°F. Doctors will get worried if a sick patient has a temperature that varies from

makvit [3.9K]

Answer:

$|T- 98.6| \geq 3$

And in order to solve this we have two possibilities:

Solution 1

$T -98.6 \leq -3$

And solving for T we got:

$T \leq 98.6- 3$

$T\leq 95.6$

Solution 2

And the other options would be:

$T -98.6 \geq 3$

$T \geq 101.6$

Step-by-step explanation:

For this case we can define the variable os interest T as the real temperature and we know that if we are 3 F more than the value of 98.6 we will be unhealthy so we can set up the following equation:

$|T- 98.6| \geq 3$

And in order to solve this we have two possibilities:

Solution 1

$T -98.6 \leq -3$

And solving for T we got:

$T \leq 98.6- 3$

$T\leq 95.6$

Solution 2

And the other options would be:

$T -98.6 \geq 3$

$T \geq 101.6$

Jen says that the solutions of the inequality -2(3 – x) > 2x – 6 are all real numbers. Do you agree with your friend? Explain

Maslowich

Answer:

I disagree

'No it won;t

Step-by-step explanation:

Given the inequality functions;

-2(3 – x) > 2x – 6

Open the parenthesis

-2(3) -2(-x) > 2x - 6

-6 + 2x > 2x - 6

Collect like terms

2x-2x > -6 + 6

0x > 0

x > 0/0

<em>The value of x does not exist on any real number. I disagree with my friend since the value of x is an indeterminate function. If the inequality were ≥, it won't change anything as the value of x won't still exist on any real number </em>
