when Larissa's watch is fully charged, it can last for up to 20 hours before running out of battery. It has been 12 hours since Larissa's watch was fully charged. Write an inequality to describe the situation, then complete the sentence
Answers
Answer:
x + 12 ≤ 20 x=8
Step-by-step explanation:
Since Larissa is able to use it up for 20 hours and she has been using it for 12 hours now so add 12 with 12 and 20 with 12 then subtract the sum from the added numbers and you will get 8
So Larissa has 8 hours left on her watch before it needs to charge

Miko has a vast collection of books in her library. English books make up
3
8
of her collection.
5
7
of the remaining books are Chinese books and the rest are German books. How many books are there in her book collection if there are 75 Chinese books?
Answers
Answer:
168 books
Step-by-step explanation:
Given
[tex]English = \frac{3}{8}[/tex]
[tex]Chinese = \frac{5}{7}[/tex] of the remaining books
Required
Determine the total number of books
If the proportion of the English books is 3/8, the the remaining is:
[tex]Remaining = 1 - English[/tex]
[tex]Remaining = 1 - \frac{3}{8}[/tex]
Take LCM
[tex]Remaining = \frac{8 - 3}{8}[/tex]
[tex]Remaining = \frac{5}{8}[/tex]
From the question, we understand that:
[tex]Chinese = \frac{5}{7}[/tex] of the remaining books
This means:
[tex]Chinese = \frac{5}{7} * \frac{5}{8}[/tex]
[tex]Chinese = \frac{5*5}{7*8}[/tex]
[tex]Chinese = \frac{25}{56}[/tex]
From the question, we also understand that 75 are Chinese books.
The total number of books can then be calculated using:
[tex]Chinese = \frac{25}{56} * Total[/tex]
Substitute 75 for Chinese
[tex]75 = \frac{25}{56} * Total[/tex]
Make Total the subject:
[tex]Total = \frac{56 * 75}{25}[/tex]
[tex]Total = \frac{4200}{25}[/tex]
[tex]Total = 168[/tex]
There are 168 books are there in her book collection if there are 75 Chinese books.
Given
Miko has a vast collection of books in her library.
English books = 3/8
Chinese books = 5/7.
Ratio proportion;A ratio is a comparison of two or more numbers that indicates their quantities in relation to each other.
The proportion of the English books is 3/8, the remaining is:
[tex]\rm Remaining\ books=1-\dfrac{3}{8}\\ \\ Remaining\ books=\dfrac{8-3}{8}\\\\ Remaining\ books=\dfrac{5}{8}[/tex]
Then,
Chines books = ratio of Chinese book × ratio of remaining books × Total books
[tex]\rm 75=\dfrac{5}{7}\times \dfrac{5}{8}\times Total \ books\\\\Total \ books =\dfrac{75 \times 7\times 8}{5\times 5}\\\\Total \ books =3\times 56\\\\Total \ books=168\\[/tex]
Hence, there are 168 books are there in her book collection if there are 75 Chinese books.

3 ounces of 1/4 of the package of sunflower seeds. How many ounces of sunflower seeds are in the whole package? Show or explain your reasoning.
Answers
Answer:
12 oz.
Step-by-step explanation:
I'm not 100% sure what you mean exactly, but I'll answer as well as can. So since 3 ounces makes up 1/4 of the bag, to find what the whole bag would be, we'd just have to take 3 x 4, which means there are 12 oz. in a bag.

Answer:
We conclude that:
The average rate = -1
Step-by-step explanation:
We need to find the Average Rate of Change from x = -2 to x = 1.
From the table it is clear that:
at x₁ = -2, f(x₁) = 3
at x₂ = 1, f(x₂) = 0
The formula to determine the average rate of change from x = -2 to x = 1.
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [0 - 3] / [1-(-2)]
= -3 / 3
= -1
Therefore, we conclude that:
The average rate = -1

I am really stuck it would mean the world if you could help :)
Answers
Step-by-step explanation:
Substituting value of x in the equation we get the answers.
The required values are F(12.6) = 5.028 and F(-1.09) = 3.9328 for the given function.
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function is given in the question as:
F(x) = 0.08x + 4.02
We have to evaluate the values F(12.6) and F(-1.09) for given function.
As per the question, we have
F(x) = 0.08x + 4.02 ....(i)
For evaluate the value F(12.6),
Substitute the value of x = 12.6 in the given function,
F(12.6) = 0.08(12.6) + 4.02
F(12.6) = 1.008 + 4.02
F(12.6) = 5.028
For evaluate the value F(-1.09),
Substitute the value of x = -1.09 in the given function,
F(-1.09) = 0.08(-1.09) + 4.02
F(-1.09) = -0.0872 + 4.02
F(-1.09) = 3.9328
Thus, the required values are F(12.6) = 5.028 and F(-1.09) = 3.9328 for the given function.
