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:

=====

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

$\hrulefill$

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:

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)

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

Alex Ar [27]

Answer:

Step-by-step explanation:

Step 1- Substitute the expression.

$\frac{5(4-2(-3))}{2(4)+(-3)}$

Step 2- Multiply to simplify.

$\frac{5(4+6)}{8-3}$

Step 3- Simplify the parenthesis.

$\frac{5*10}{8-3}$

Step 4- Subtract.

$\frac{5*10}{5}$

Step 5- Reduce the fraction with 5.

$\frac{5*10}{5}$ The 5's are crossed out when simplified.

= 10
