Find the measure of angle D, and the perimeter and area of parallelogram abcd

Alecsey [184]

Answer:

It is the last choice.

Step-by-step explanation:

m < D = 180 - 28 = 152 degrees ( as same side angle add up to 180 degrees).

The perimeter = 2*17 + 2*25 = 84 cm ( as opposite sides of a parallelogram are congruent).

The area = base * height = 8 * 25

= 200 cm^2.

Multiply the matrices. (Please help!)

Ainat [17]

9514 1404 393

Answer:

$\left[\begin{array}{cc}12&1\\-4&1\\-11&28\end{array}\right]$

Step-by-step explanation:

The element at row i column j in the product is the dot-product of row i of the first matrix and column j of the second matrix. For example, row 2 column 1 of the product is ...

(row 2) · (column 1)

[3, -2, 4] · [2, 7, 1] = (3)(2) +(-2)(7) +(4)(1) = 6 -14 +4 = -4

The attachment shows the complete product matrix. It is convenient to let a spreadsheet or graphing calculator do the tedious repetitive arithmetic.

Work out the sum of 1/6 , 4/5 and 2/3 Give your answer as a mixed number in simplest form.

mash [69]

Answer:

1 29/30

Step-by-step explanation:

First find the least common denominator of 1/6, 4/5, and 2/3. The least common denominator of that list is: 30.

So let's convert all of these fractions to a denominator of 30.

Here are the newly converted fractions:

5/30, 24/30, 20/30.

So now add all of them together. 5/30+24/30+20/30=(5+24+20)/30, which is equal to: 49/30 = 1 19/30.
