I need help with this problem.
sdas [7]

Answer:

  \text{4}\quad -3x^{-1}+x^{-2}

Step-by-step explanation:

The answer choices suggest there is a common factor of (x+2) that can be removed from numerator and denominator.

The denominator factors as ...

  x^3+2x^2=x^2(x+2)

The numerator obviously has no factors of x. We can try any of several means to determine if (x+2) is a factor. I tried synthetic division and found that the numerator can be written as ...

  -3x^2-5x+2=(-3x+1)(x+2)

Then the expression simplifies to ...

  \dfrac{-3x^2-5x+2}{x^3+2x^2}=\dfrac{(-3x+1)(x+2)}{x^2(x+2)}\\\\=\dfrac{-3x+1}{x^2}=\dfrac{-3x}{x^2}+\dfrac{1}{x^2}=-3x^{-1}+x^{-2} \qquad\text{matches choice 4}

Mrs. Smith teaches junior high school. During a class party in fourth
MArishka [77]

Question is Incomplete, Complete question is given below.

Mrs.Smith teaches junior high school. During a class party in fourth period, she used 4/5 liters of soda for 12 students. If she had a class party in fifth period and used the same serving size, how many liters did she use for 30 students?

Answer:

Mrs. Smith used 2 liters of soda for 30 students.

Step-by-step explanation:

Given:

Number of students = 12

Amount of soda used for 12 students = 4/5 liters

We need to find amount of soda used for 30 students.

For 12 students  = 4/5 liters of soda used

For 30 students =  the amount of soda used

By Using Unitary Method we get

Amount of soda used = \frac{4\times30}{5\times12}=\frac{120}{60} =2 \ litres

Hence Mrs. Smith used 2 liters of soda for 30 students.

To what decimal place should each answer be rounded? How many significant figures does the rounded answer have? A. 9 cm+2.8 cm=1
FromTheMoon [43]

Answer:

a) rounded to the ones place and 2 significant figures.

b) rounded to tenths place and 1 significant figure.

Step-by-step explanation:

Significant figures are the number of needed place values for accuracy. Round each number according to the least number of significant figures within the problem.

A. 9 cm+2.8 cm = 11.8 cm rounds to 12 which has 2 significant figures. Round to the ones place value since 9 has the least number of significant figures.

B. 0.135 atm+0.6 atm = 0.735 atm rounds to 0.7 atm which has 1 significant figure. Zero preceding the value is not considered significant. Round to the tenths place value since 0.6 has the least number of significant figures.
