What is the mixed number answer 4 4/9 + 8 7/9
Answers
Hello there. To solve this question, we'll have to remember some properties about mixed numbers.
Given the mixed number a b/c, we can write it as and it is the same as
Therefore in the expression:
[tex]4\frac{4}{9}+8\frac{7}{9}[/tex]We rewrite it as
[tex]4+\frac{4}{9}+8+\frac{7}{9}[/tex]Adding the fractions, we have:
[tex]12+\frac{11}{9}=\frac{119}{9}[/tex]And we have to write the answer in mixed fraction form, therefore we perform
[tex]\frac{119}{9}=\frac{117+2}{9}=13\frac{2}{9}[/tex]This is the answer we're looking for.

In a textbook, 900 digits are used for the page numbers. How many pagesare in the textbook, starting with page 1? (Hint: First find how many digitsare used for pages 1-9 and 10-99.)
Answers
Given:
900 digits are used for the page numbers. How many pages are in the textbook, starting with page 1
We will find the number of the pages of the book as follows
The number of digits from 1 to 9 = 9
The number of digits from 10 to 99:
There are 90 numbers, each number has 2 digits
So, the number of digits from 10 to 99 = 90 x 2 = 180
The number of digits from 100 to 999:
There are 900 numbers, and each number has 3 digits
so, the number of digits from 100 to 999 = 900 x 3 = 2700
The overall digits are given = 900
So, number of digits from 1 to 99 = 9 + 180 = 189
Subtract 189 from 900 = 900 - 189 = 711
Divide 711 by 3 = 237
So, the number of pages that have 3 digits = 237
So, the number of pages of the book = 237 + 99 = 336
So, the answer will be 336 pages

Step-by-step explanation:
Given problem,
→ 5/7 - (3/14 + 3/14)
Let's solve the given problem,
→ 5/7 - (3/14 + 3/14)
→ (5/7) - (6/14)
→ ((5 × 2)/(7 × 2)) - (6/14)
→ (10/14) - (6/14)
→ (10 - 6)/14
→ 4/14 = 2/7
Hence, required answer is 2/7.

Abrha will be spending $701 monthly, just by arithmetic operation.
What is the arithmetic operation?
The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.
If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.
Abrha lives in an apartment,
electric bill, $44.90 = $50
TV streaming service, $24.99 = $25
Rent, $625.85 = $626
So the Total expenses will be (50+25+626) = $701 just by arithmetic operation
Hence Abrha will be spending $701 monthly.

When people take medicine, the drug gets metabolized by the body and eliminated at a constant rate.
Suppose the initial amount of a drug in the body is 549 mg and it is eliminated at a rate of 12% per hour.
Let f(x) refer to the amount of drug left in the body after I hours.
(a) Write down an exponential function to model this situation. Write your answer using function

(b) How much of the drug is left in the body after 12 hours? Round to the nearest whole number.
(c) How much of the drug is left in the body after 180 minutes? Round to the nearest whole number
Part a)
Let
t -----> number of hours
f(x)=a(1+r)^t
where
a=549 mg
r=12%=0.12
substitute
f(x)=549(1+0.12)^t
f(x)=549(1.12)^tPart b)

substitute in the function
f(12)=549(1.12)^12
f(12)=2,139 mgPart c)
For t=180 minutes
Remember that

#3) Ulices was charged $140 plus a pick up charge of $20 to ship 4 identical boxesbys Fast Ship. The pick up charge applies regardless of how many boxes are pickedup. What would have been the change to Ulices' account if he had shipped just 1box?
Answers
To determine the Ulices's account if he shipped just 1 box, calculate the charge for one box. To calculate the charge, compute the quotient between the charge for 4 boxes between 4 boxes, just as folow:
charge per one box = 140/4 = 35
Hence, for 1 box the charge is $35
Due to it is necessary to pay $20 idependenty of the number of boxex, you sum $20 to the cost for one box:
New Ulices's account = $35 + $20 = $55
Hence, Ulices's account would have been of $55

Factor theorem is usually used to factor and find the roots of polynomials. A root or zero is where the polynomial is equal to zero. Therefore, the theorem simply states that when f(k) = 0, then (x – k) is a factor of f(x).

Translate thefollowing phaseinto an inequality-3 times r is at least 33A) inequality B) Solve the equality for r.C) express the solution in interval notation.
Answers
Given the phrase:
-3 times r is at least 33
Let's translate the given phrase into an inequality.
• Part A.
Let's figure out the inequality in steps.
-3 times r is written as:
-3r
-3 times s is at least 33 means that -3r is greater than or equal to 33.
Hence, we have the inequality:
[tex]-3r\ge33[/tex]• Part B.
Let's solve the inequality for r.
To solve for r, divide both sides of the inequality by -3:
[tex]\begin{gathered} \frac{-3r}{-3}\ge\frac{33}{-3} \\ \\ r\le-11 \end{gathered}[/tex]• Part C.
Let's express the solution in interval notation.
