How do you convert binary numbers to decimal numbers

Mathematics
1 answer:
telo118 [61]3 years ago
5 0
An easy method of converting decimal to binary number equivalents is to write down the decimal number and to continually divide-by-2 (two) to give a result and a remainder of either a “1” or a “0” until the final result equals zero.

Solve the following system of equations. What is the y value of the solution?
Svet_ta [14]

Answer:

y = 2

Step-by-step explanation:

x + 5y - 10 = 0

X = 4y - 8

since x is given as = 4y - 8 we can use this in first equation

replace x with 4y - 8

x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms

9y - 18 = 0 add 18 to both sides of the equation

9y = 18 divide both sides by 9

y = 2

Which of the expressions is rational
miv72 [106K]

Answer:

the third one

Step-by-step explanation:

the square root of 25 is 5. 5+2 = 7.

this is a rational number (the set of all integers and fractions).

the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.

45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.

a car travels 1.2 miles from point a to point b. the car then turns at point b and travels 1.8 miles to point c before heading b
wel

<em>Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.</em>

<em>                               b² = a² + c² - 2ac(cosB)</em>

<em>Substituting the known values,</em>

<em>                          (1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)</em>

<em>The value of B from the equation is 48.6°. </em>

Someone help! I’m not good at these problems!
Evgen [1.6K]

Answer:

I beliive it is 16, but haven't done this in a bit haha

Step-by-step explanation:

So bisect means to "split in half" aka segment BD is directly in the middle of triangle ABC. This means we can look at the half of the triangle we know (ABD). We see a 16, so therefore x should be 16.

(again, hopefully I am correct)
