Calculate the volume of a rectangular prism with a length of 4.4 cmcm, a width of 3.1 cmcm, and a height of 6.3 cmcm. (As before

sergeinik [125]

Answer: 85.93 cm³ .

Step-by-step explanation:

We know that the volume of the rectangular prism is given by :-

$V=\text{length x width x height}$

Given : A rectangular prism has

length =4.4 cm, width = 3.1 cm, and a= height =6.3 cm.

Then, the volume of the rectangular prism will be :

$V=4.4\times3.1\times6.3=85.932\approx85.93\ cm^3$

Hence, the volume of a rectangular prism is 85.93 cm³ .

Combine like terms to simplify the expression:<br> 1.17-0.07a+(-3.92a)

Pachacha [2.7K]

After combining like terms and simplifying $1.17-0.07a+(-3.92a)$ we get $1.17-3.99a$

Step-by-step explanation:

We need to combine like terms to simplify the expression:

$1.17-0.07a+(-3.92a)$

Like terms: The terms are like when they have same variable and same exponent.

Solving:

$1.17-0.07a+(-3.92a)\\=1.17-0.07a-3.92a\\=1.17+(-0.07a-3.92a)\\=1.17+(-3.99a)\\=1.17-3.99a$

So, After combining like terms and simplifying $1.17-0.07a+(-3.92a)$ we get $1.17-3.99a$

What is addition and subtraction

choli [55]

$\huge\text{Hey there!}$

$\huge\textsf{What is addition \& subtraction?}$

$\huge\textbf{What is addition?}$

$\bullet\large\textbf{ Well, \underline{addition} simply means when you're ADDING}\\\large\textbf{2 or more numbers from each other to get the result of}\\\large\textbf{a number.}$

$\huge\textbf{Random notes}$

$\star\large\textbf{ Usually, you start working with addition when you're in}\\\large\textbf{pre-kindergarten (pre-k also known as head-start)}\\\\\star\large\textbf{ When, you're adding you are going upward.}\\\\\star\large\textbf{ Addition sometimes come after you learn how to count}\\\large\textbf{the basic numbers and so forth because adding never}\\\large\textbf{ends if you really think about.}$

$\huge\textbf{Example:}$

$\heartsuit\large\textbf{ 2 \boxed{\bf +} 5 = 7}\\\\\\\heartsuit\large\textbf{ You got the result of 7 because you started at 2 \& went}\\\larg\textbf{up 5 spaces to your right on your number and you landed}\\\large\textbf{on 7.}$

$\huge\textbf{What is subtraction?}$

$\bullet\large\textbf{ Well, subtraction simply means you're taking away. Often}\\\large\textbf{people call it take aways.}$

$\huge\textbf{Random notes:}$

$\star\large\textbf{ Usually, you start working with subtraction when you're}\\\large\textbf{in pre-kindergarten (pre-k also known as headstart)}\\\\\star\large\textbf{When you're subtracting you are doing downward.}\\\\\star\large\textbf{You focus more on subtraction when you're counting}\\\large\textbf{backwards.}$

$\huge\textbf{Example:}$

$\heartsuit\large\textbf{ 7 \boxed{\bf -} 5 = 2 }\\\\\\\heartsuit\large\textbf{ 7 \boxed{\bf -} 2 = 5}\\\\\\\heartsuit\large\textbf{ For equation \#1. you begin at 7 and go BACK 5 spaces}\\\large\textbf{and you should have landed on 2.}\\\\\\\heartsuit\large\textbf{ For equation \#2. you begin at 7 \& go BACK 2 spaces}\\\large\textbf{and you should have landed on 5.}$

$\huge\textsf{KEEP IN MIND:}$

$\circ\large\textsf{ Addition OPPOSITE is subtraction \& subtraction OPPOSITE is}\\\large\textsf{addition.}$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
