Give the following number in Base 16<br>NO LINKS!!! ​
olga nikolaevna [1]

Answer:

\large{\boxed{35_{10} = \sf 23_{16}}}

Explanation:

\sf Given : 35_{10}

Compute:

35 ÷ 16 = 2.1875 = 2R3

2 ÷ 16 = 0.125 = 0R2

Jot down the remainders:

  • 3        ↑
  • 2        ↑

======

\sf Answer :  \ 35_{10}   =  23_{16}

\hrulefill

Let's look at another example:  \sf 325_{10} = [?]_{16}

Compute:

325 ÷ 16 = 20.3125 = 20R5

20 ÷ 16 = 1.25 = 1R4

1 ÷ 16 = 0.0625 = 0R1

Jot down remainders:

  • 5        ↑
  • 4        ↑
  • 1         ↑

=====

\sf 325_{10} = [145]_{16}

\hrulefill

Another example: \sf 500_{10} = [?]_{15}

Compute:

500 ÷ 15 = 33.33... = 33R5

33 ÷ 15 = 2.2 = 2R3

2 ÷ 15 = 0.13... = 0R2

Jot down remainders:

  • 5      ↑
  • 3       ↑
  • 2       ↑

=====

\sf 500_{10} = [235]_{15}

Which equation represents a proportional relationship that has a constant of proportionality equal to One-fifth?
Sedbober [7]

Answer:

Option C)

y = \dfrac{1}{5}x  

Step-by-step explanation:

We are given the following in the question:

y \propto x

Removing the sign of proportionality and introducing the constant of proportionality, we have

y = kx

where k is constant of proportionality.

We are given

k = \dfrac{1}{5}

Putting value, we get,

y = \dfrac{1}{5}x = \dfrac{x}{5}

Thus, the equation representing the relationship is

Option C)

y = \dfrac{1}{5}x
