What numbers add up to 3 & multiple to 10

2 answers:

Well, factors of 10 are:
1 and 10
and
2 and 5

Those don't add up to three. However, if it was -10, then 5 and -2 would add up to three.

There are no real numbers that can do that job.

The numbers are

<em> 1.5 + i √7.75</em>
and
<em>1.5 - i √7.75</em>

These are called 'complex numbers'. The symbol ' i ' stands for √-1 .

==================================================

If either the ' 3 ' or the ' 10 ' was actually supposed to be negative,
then the two numbers would be<em> 2 </em> and<em> -5 .</em>

Match the real-world problem to its constant of proportionality.

irakobra [83]

Answer:

a. $18.36 for 3 pizzas : k = 6.12

b. $4.17 for 3 pounds of bananas . k = 1.39

c. $16.48 for 4 pounds of potatoes . k = 4.12

d. 2 cups of flour to make 24 cookie . k = 12

Step-by-step explanation:

PROPORTIONALITY:

Two quantities x and y are said to proportional to each other

if for x ∝ y , x = y k.

Here, k is called the PROPORTIONALITY CONSTANT.

⇒ $x \propto y \implies k = \frac{x}{y}$

Now, for the given quantities:

a. $18.36 for 3 pizzas [box]

Here, $k = \frac{x}{y} = \frac{18.36}{3} = 6.12$

So, the proportionality constant is 6.12.

b. $4.17 for 3 pounds of bananas [box]

Here, $k = \frac{x}{y} = \frac{4.17}{3} = 1.39$

So, the proportionality constant is 1.39.

c. $16.48 for 4 pounds of potatoes [box]

Here, $k = \frac{x}{y} = \frac{16.48}{4} = 4.12$

So, the proportionality constant is 4.12.

d. 2 cups of flour to make 24 cookies

Here, $k = \frac{x}{y} = \frac{24}{2} = 12$

So, the proportionality constant is 12.
