Answer:
15 nuts do not get found.
Step-by-step explanation:
Given that Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found.
Total number of nuts squirrel had hidden = 40
Proportion of nuts not found to total = 3/(3+5) = 3/8
Hence out of 40, nuts not found =3/8(40) = 15 nuts.
15 nuts would not be found and 25 nuts would be found if squirrel had hidden in total 40 nuts.
This is because the proportion of found:unfound = 5:3
Hence 25:!5 =5:3 satisfies this
15 nuts are not found.
Answer:

Step-by-step explanation:
Let's start by using distributive multiplication:

So:

Grouping like terms:

Now,
is equal to:

In this sense:

In order to satisfied the equality:

Hence, from (1), let's solve for a:

And from (2), let's solve for b:

Let's verify the result evaluating the values of a and b into the original equation:

As you can see, the values satisfy the equation, therefore, we can conclude they are correct.
I couldn’t really read this question but to multiply two decimal numbers you first ignore the decimals and multiply the numbers and then add in the decimal based off how many were in the question. For example, 1.1 x 0.4= 0.44. I hope this helps you
