A picture frame (see figure) has a total perimeter of 3 feet. The width of the frame is 0.64 times its length. Find the dimensio

Naya [18.7K]

Answer:

$\approx 0.59\text{ ft by }0.91\text{ ft}$

Step-by-step explanation:

Let $\ell$ represent the length of the rectangle. The width can be represented as $0.64\ell$ .

The perimeter of a rectangle with lengths $l$ and $w$ is given by $p=2l+2w$ .

Thus, we have:

$2\ell+2(0.64\ell)=3,\\2\ell +1.28\ell=3,\\3.28\ell=3,\\\ell=0.91463414634\approx 0.91$

The width is then $0.64(0.91463414634)=0.58536585365\approx 0.59$ .

Write a paragraph explaining what scattered plots are and how to solve them. Make sure to give details, key terms and an example

Lunna [17]

Answer:

x = 59°

y = 67°

Step-by-step explanation:

x = y - 8

x + y + 54 = 180

(y - 8) + y = 180 - 54

2y - 8 = 126

2y = 134

y = 67°

x = 59°

Which operation can be used with the augmented matrix below?

ycow [4]

Answer:

Multiply row 2 by-1 and add it to row 3.

Step-by-step explanation:

The given augmented matrix is $\left[\begin{array}{ccc}3&-21&15\\15&8&15\\-2&-1&3\end{array}\right]$

The permissible row operations are:

1. Switching rows

2. Multiplying a row by a nonzero constant.

3. Adding/Subtracting two rows

Therefore the correct option is: Multiply row 2 by-1 and add it to row 3.
