Answer:

Length = 15 cm, width = 12 cm, Perimeter = 54 cm

Step-by-step explanation:

The ratio of the length and breadth of a rectangle is 5:4 and its area is 180 cm².

Length = 5x

Breadth = 4x

Area of rectagle,

A = bl

180 = 5x × 4x

180 = 20x²

x² = 9

x = 3

Length = 5x = 5(3) = 15 cm

Width = 4x = 4(3) = 12 cm

Perimeter of rectangel,

P = 2(l+b)

= 2(15+12)

= 54 cm

Hence, this is the required solution.

Selected accounts with a credit amount omitted are as follows: Work in Process Apr. 1 Balance 7,000 Apr. 30 Goods finished X 30
lawyer [7]

Answer:

$29,900

Step-by-step explanation:

The computation of the  balance of Work in Process as of April 30 is shown below:

= Opening balance of work in process + direct material cost + direct labor cost + factory overhead cost - goods finished

= $7,000 + $78,400 + $195,000 + $136,500 - $387,000

= $29,900

The  direct material cost + direct labor cost + factory overhead cost is known as manufacturing cost

How much is 1.4 kg minus 650 grams
faltersainse [42]
First of all you have to convert kg to grams

so there is 1 kg in 1000g
.4 kg is 400g
1000+400= 1400g

1400-650 = 750 kg

that's your final answer

PLEASE HELP!! If the endpoints of have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of ?
dimaraw [331]

M refers to midpoint.

A(9, 8) \\B(-1, -2) \\M(\frac{x_1-x_2}{2}, \frac{y_1-y_2}{2}) \\M(\frac{9-(-1)}{2}, \frac{8-(-2)}{2}) \\M(\frac{10}{2}, \frac{10}{2})\Longrightarrow\boxed{M(5, 5)}

Hope this helps.
