Answer:

15 meters

Step-by-step explanation:

The piece is made out of two pieces of parachute, a short one and a long one. The short on is 21 meters shorter than the longer one, if the longer one is 36 meters than the short piece is 36 meters - 21 meters

36 - 21 = 15

This means that the short piece is 15 meters long

We can check this by adding the short piece and the long piece hoping that it equals the total length, 51 meters

36 + 15 = 51

That means that you were correct

Which is greater: 75% of 56 or 114.8 divided by 2.8? Explain how you know.
Umnica [9.8K]

Answer:

<em>114.8</em>

Step-by-step explanation:

When you divide 75% and 2.8 you get 0.2678

When you divide 56 and 2.8 you get 20

When you divide 114.8 and 2.8 you get 41

Fred borrows $2710 at 3.8% simple interest per month. When Fred pays the loan back 3 months later, what is the total amount that
Fantom [35]

Step-by-step explanation:

Simple interest =P (1+. R )^n

/100

Where P is the amount

R is rate (%)

n is number of years

So if you are given months your divide ➗ the number of months by 12 years

2710 *(1+ [ 3.8/100])^3/12

What is the row echelon form of this matrix?
USPshnik [31]

The row echelon form of the matrix is presented as follows;

\begin{bmatrix}1 &-2  &-5  \\ 0& 1 &  -7\\ 0&0  &1  \\\end{bmatrix}

<h3>What is the row echelon form of a matrix?</h3>

The row echelon form of a matrix has the rows consisting entirely of zeros at the bottom, and the first entry of a row that is not entirely zero is a one.

The given matrix is presented as follows;

\begin{bmatrix}-3 &6  &15  \\ 2& -6 &  4\\ 1&0  &-1  \\\end{bmatrix}

The conditions of a matrix in the row echelon form are as follows;

  1. There are row having nonzero entries above the zero rows.
  2. The first nonzero entry in a nonzero row is a one.
  3. The location of the leading one in a nonzero row is to the left of the leading one in the next lower rows.

Dividing Row 1 by -3 gives:

\begin{bmatrix}1 &-2  &-5  \\ 2& -6 &  4\\ 1&0  &-1  \\\end{bmatrix}

Multiplying Row 1 by 2 and subtracting the result from Row 2 gives;

\begin{bmatrix}1 &-2  &-5  \\ 0& -2 &  14\\ 1&0  &-1  \\\end{bmatrix}

Subtracting Row 1 from Row 3 gives;

\begin{bmatrix}1 &-2  &-5  \\ 0& -2 &  14\\ 0&2  &4  \\\end{bmatrix}

Adding Row 2 to Row 3 gives;

\begin{bmatrix}1 &-2  &-5  \\ 0& -2 &  14\\ 0&0  &18  \\\end{bmatrix}

Dividing Row 2 by -2, and Row 3 by 18 gives;

\begin{bmatrix}1 &-2  &-5  \\ 0& 1 &  -7\\ 0&0  &1  \\\end{bmatrix}

The above matrix is in the row echelon form
