How to write two different pairs of decimals whose sums are 14.1. One pair should involve regrouping

1 answer:

3 0

To solve, first let’s define regrouping:
=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.

So let us have the non-regrouping decimal number:
=> 8.4
Next, the other regrouping decimal
=> 5.7

So now let us show how it becomes 14.1:
8.4
+5.7
14.1

Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
Thus, the answer is 14.1

We’re learning polynomial functions and I have absolutely no idea how to do it. The first question is “State the degree and lead

ycow [4]

Let's begin by defining the key terminologies:

The degree of a polynomial simply refers to the term with the highest exponent in a polynomial

For example:

$\begin{gathered} a+8\Rightarrow a^1+8 \\ =a^1+8 \\ \text{We will observe that the variable ''a'' has a degree of ''1''} \\ \text{Therefore, the degree of this polynomial will be ''1''} \\ \\ \text{If we have}\colon5a^2+10 \\ 5a^2+10 \\ \text{We will observe that the variable ''a'' has the highest degree of ''2''} \\ \text{Therefore, the degree of this polynomial will be ''2''} \\ \\ \text{If we have}\colon3a^4+2a^2+10a+10 \\ 3a^4+2a^2+10a+10 \\ \text{We will observe that the variable ''a'' has the highest degree of ''4'' } \\ \text{Therefore, the degree of this polynomial will be ''4''} \end{gathered}$

The leading coefficient simply refers to the coefficient of the term that has the highest degree in a polynomial

For example:

$\begin{gathered} \text{If we have}\colon a+8 \\ a+8 \\ \text{''a'' is the variable having the highest degree, that degree is ''1''} \\ \text{The coefficient of the variable ''a'' is 1. Hence, the leading coefficient is ''1''} \\ \\ \text{If we have}\colon5a^2+10 \\ 5a^2+10 \\ \text{''}5a^2\text{'' is the variable with the highest degree},\text{ that is ''2''} \\ \text{The coefficient of the variable ''}5a^2\text{'' is 5. Hence, the leading coefficient is ''5''} \\ \\ \text{If we have}\colon3a^4+2a^2+10a+10 \\ 3a^4+2a^2+10a+10 \\ \text{ ''}3a^4\text{'' is the variable with the highest degree},\text{ that is ''4''} \\ \text{The coefficient of the variable ''}3a^4\text{'' is ''3''. Hence, the leading coefficient is ''3''} \end{gathered}$

To find the x-intercept, what do you do?

jonny [76]

Answer: To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept. Just look on the graph for the point where the line crosses the x-axis, which is the horizontal axis. That point is the x intercept.

A teacher wants to build a scale model of the Earth and Pluto to compare their sizes. The Earth has a diameter of approximately

koban [17]

Answer:

Step-by-step explanation:

A scale model means that the ratios stay the same.

Therefore, Earth's diameter divided by Pluto's diameter is equal to the ratio of Earth's model's diameter divided by Pluto's model's diameter.

We can write this as

8000 / 1500 = 32/ Pluto's model's diameter. Representing Pluto's model's diameter as P, we can say

8000 / 1500 = 32 / P

multiply both sides by 1500 to remove a denominator

8000 = 32 * 1500 / P

multiply both sides by P to remove the other denominator

8000 * P = 32 * 1500

divide both sides by 8000 to isolate the P

P = 32 * 1500/8000

= 6 inches
