Answer: sophia worked 6 hours, London worked 5 hours.

Step-by-step explanation:

Since two of them will work for a combined period of 11hours, then we denote the number of hours spent by sophia to be x hours, then number of hours spent by london will become "11-x" hours.

Number of shirts that can be ironed per hour for sophia= Ns = 40shirts/hour

Number of shirts that can be ironed per hour for london= Nl= 25shirts/hour

Hence: the system that can be used to describe the number of hours both worked with can be denoted as:

[Ns * x] + [Nl *(11-x) ] = 365

[40x] + [25 * (11-x)]=365

40x + 275 + 25x = 365

15x = 90

x=6hours.

Hence, for the combined 11hours worked)

Number of hours worked by sophia =6hours

Number of hours worked by London = 5hours.

2. A drawing of a sailboat was made using a rectangle and two right triangles, as shown. What
Zarrin [17]

Answer:

  45 square centimeters

Step-by-step explanation:

The area of the triangle is given by ...

  A = (1/2)bh

where b is the base, 2 cm + 3 cm = 5 cm, and h is the height, 6 cm.

  A = (1/2)(5 cm)(6 cm) = 15 cm^2

__

The area of the rectangle is given by ...

  A = bh

where b is the base, 12 cm, and h is the height, 2.5 cm.

  A = (12 cm)(2.5 cm) = 30 cm^2

__

The area of the whole figure is the area of the triangle added to the area of the rectangle:

  drawing area = 15 cm^2 + 30 cm^2 = 45 cm^2

2 Rita bought three and forty-eight hundredths pounds of bananas at the store. How is this number written in expanded notation?
boyakko [2]

The cost of bananas = $ 3.48

This can be written as :                                                                                            

this number written in expanded notation as : (3 × 1) + (4 × 0.1) + (8 × 0.01)

3+0.4+0.08 = 3.48

Hence, 1st option is correct.

Hariette would like to review the income and expenses that were actually paid last month so she can determine how much to set as
Brrunno [24]

Answer:

Hybrid basis

Step-by-step explanation:

There are different methods of accounting used by businesses depending on their peculiar needs. Below are the type of accounting methods:

- Cash basis is when revenues and expenses are recognised when cash is recieved or paid out.

-Accrual basis is when revenue and expenses are recognised when they are earned. For example if services are rendered to a client that will pay in a week's time, since service has already been given it is considered that the future payment has been earned.

- Modified basis combines elements of cash and accrual basis. For example considering short term assets like accounts receivable and accounts payable as cash items. Long term assets are recorded on accrual basis.

- Hybrid basis is used when cash and accrual methods are used for various expenses and tax. Mostly it is used for internal accounting purposes.

In this scenario Hariette would like to review the income and expenses that were actually paid last month. This requires a cash basis that shows actual amount recieved and paid last month. Account receivable and payable are not considered.

In setting aside money for tax she will employ accrual basis accounting. It is an expense that is estimated for future use.

So the hybrid basis is the method that will be most suitable.

Find the Perimeter of this shape. Can someone explain to me how to find the perimeter.
Agata [3.3K]
The little lines in each side show that the sides are the same length but you also need to find the length of the smaller side which isn’t the same. For this imagine that the shape is split into a square and a triangle and you need to find the long side of the triangle using Pythagoras
a^2 + b^2 = c^2
20^2 + 20^2 = 800
Square root of 800 = 28.3
Then do 28.3-20=8.3
So I think the answer is 20+20+20+20+20+8.3=108.3 cm
