Answer:

In HEX, it would be 88.

In DEC, it would be 136.

In Oct, it would be 210.

Binary, how to add numbers together.

     1101101

+       11011

10001000

This is just like adding regular numbers together.

For example, when you add 88 to 55, this is what will happen

   1(r)

  88

+ 55

13(+1)  3

143

With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.

How to evaluate a given mathematical expression with variables if values of the variables are known?

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

For this case, we have:

Amount of aspirin in a person's body (in milligrams) after t hours of taking the medicine is:

[tex]a = 500\times(\dfrac{3}{4})^t[/tex] (in milligrams)

For t = 2 hours, we get:

[tex]a = 500\times(\dfrac{3}{4})^2 = 281.25 \: \rm milligrams[/tex]

Thus, the amount of aspirin that will be present in the patient's body after two hours is 281.25 milligrams.

Use the zero product property to find the solutions to the equation x2 + 12 = 7x.

Answers

Are u solving for x? And is the “x2” x to the power of 2 or is it 2x
x = 3 or x = 4

Given
x² + 12 = 7x ( subtract 7x from both sides )
x² - 7x + 12 = 0 ← in standard form
(x - 3)(x - 4) = 0 ← in factored form
Equate each factor to zero ( zero product property ) and solve for x
x - 3 = 0 ⇒ x = 3
x - 4 = 0 ⇒ x = 4

Find the equation of the line shown.

Answers

Answer:

4y + x = 8

Step-by-step explanation:

firstly, we choose any 2 points on the line

point 1 = (0,2)

point 2 = (4,1)

x1 = 0, x2 = 4

y1 = 2, y2 = 1

from,

[tex] \dfrac{y2 - y1}{x2 - x1} = \dfrac{y- y1}{x- x1} [/tex]

[tex] \dfrac{1 - 2}{4 - 0} = \dfrac{y- 2}{x- 0} [/tex]

[tex] \dfrac{ - 1}{4} = \dfrac{y- 2}{x- 0} [/tex]

Cross multiplying,

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

-x = 4y - 8

4y + x = 8
