Answer:

\Huge\boxed { 1/4}

\Huge\boxed {226•333. miles}

Step-by-step explanation:

\huge\pink{\boxed{\green{\mathcal{\overbrace{\underbrace{\fcolorbox{Black}{aqua}{\underline{\pink{✩1.solusion✩}}}}}}}}}

1. ⟾ one dozen = 12, so 2 dozen = 12×2=24

⟾ 24 Joe's doughnuts = $6

⟾ 1 Joe's doughnuts or unit / rate = $6/24 = $1/4.

⟾ so per doughnut unit rate is $ 1/4.

\huge\pink{\boxed{\green{\mathcal{\overbrace{\underbrace{\fcolorbox{Black}{aqua}{\underline{\pink{✩2.solusion✩}}}}}}}}}

2. ⟾ 24 hours = 5432 miles.

⟾ 1 hours = 5432/24 hours

⟾ 1 hours = 226•333 miles.

⟾ so aryan drove in 226•333 miles in 1 hours.

To find:

The product of prime factors of given number.

Solution:

We have,

The prime factors of given number are:

<u>2 | 96</u>

<u>2 | 48</u>

<u>2 | 24</u>

<u>2 | 12</u>

<u>2 | 6</u>

So, 96 can be written as:

96=2\times 2\times 2\times 2\times 2\times 3

Therefore, the 96 as the product of prime factors is 96=2\times 2\times 2\times 2\times 2\times 3.

What equation models the data in the table if d = number of days and c = cost?
dedylja [7]

Answer:

c=3d

Step-by-step explanation:

What equation models the data in the table if d = number of days and c = cost? Days Cost 2 6 3 9 5 15 6 18

Answer: An equation is a statement used to show the relationship between variables and shows the equality between two expressions. We want to find the relationship between the number of days and the cost.

Given that:

Days  Cost

2          6

3          9

5         15

6         18

Lets take the ratio of days to cost using the first row:

\frac{d}{c}=\frac{2}{6}\\  \frac{d}{c}=\frac{1}{3}\\c=3d

The relationship c = 3d is true for all values of days and cost
