The arrangement should be based on the decreasing degree of the terms which may be determined by the variable x as it should come first in alphabetical order. The polynomial is then,
                         10x³ + 2x²y + 2xy^4 - 3y²
The degree is equal to the sum of the exponents. Thus, the answer is 5 and it is letter D.

Part AEstimate 10/12 - 3/8 using benchmark values. Your equation must show the estimate for each fraction and the final estimate
ser-zykov [4K]

ANSWER

\text{The final estimate for the expression is }\frac{11}{24}

STEP-BY-STEP EXPLANATION

Given information

\text{Estimate }\frac{10}{12}\text{ - }\frac{3}{8}

To estimate the above expression, we need to find the factors of the denominators to get the LCM

Factors of 12 = 2 x 2 x 3

Factors of 8 = 2 x 2 x 2

From the above factors, the LCM is 2 x 2 x 2 x 3 = 24

Therefore, LCM is 24

\begin{gathered} \frac{\frac{10}{12}\text{ - }\frac{3}{8}}{24} \\  \\ =\text{ }\frac{\text{ 24(}\frac{10}{12})\text{ - 24(}\frac{3}{8})}{24} \\  \\ =\text{ }\frac{2(10)\text{ - 3(3)}}{24} \\ =\frac{20\text{ - 9}}{24} \\ =\text{ }\frac{11}{24} \end{gathered}

What is 3/8 plus 1/12
Delvig [45]
first what you have to do you have to find the common denominator which is 24
it's 24 because 8 times 3 equals 24 and 12 times 2 equals 24 so they have a like denominator so what you have to do to the bottom you have to do to the top so 8 times 3 is 24 so 3 times 3 is 9 so the new fraction is 9/24. Then 1/12 12×2=24 and 1×2= 2 so the new fraction is 2/24. that would leave you with the problem of 9/24 + 2/24 which is 11/ 24

Unit 3, Lesson 7
aksik [14]

Answer:

Find the complete table in attached file.

Step-by-step explanation:

Find the Incomplete table in attached file

Given:

A car travels 55 miles per hour for 2 hours.

So the speed of the car 55 miles per hour is constant for 2 hours.

Using speed  formula.

Speed=\frac{distance}{time}

Second row.

From the second row of the table time = \frac{1}{2}=0.5\ sec and speed is constant speed = 55\ mi/hr, so we need to find only distance.

Speed=\frac{distance}{time}

55=\frac{distance}{0.5}

distance = 55\times 0.5

distance = 27.5\ mi

Third row.

From the third row of the table time =1\frac{1}{2}=\frac{3}{2} = 1.5\ sec and speed is constant speed = 55\ mi/hr, so we need to find only distance.

Speed=\frac{distance}{time}

55=\frac{distance}{1.5}

distance = 55\times 1.5

distance = 82.5\ mi

Fourth row.

From the fourth row of the table distance =110\ miles and speed is constant speed = 55\ mi/hr, so we need to find time.

Speed=\frac{distance}{time}

time=\frac{distance}{speed}

time=\frac{110}{55}

time = 2\ sec

Therefore we complete the table from the above calculation.
