Answer:

3.4 lessons per week

Step-by-step explanation:

So to find the number of lessons for 6 chapters we need to multiply 8.5 by 6:

8.5 × 6 = x

x = 51 - so we need 51 lessons to finish six chapters

To find the number of lessons per week, we need to divide the number of lessons by the number of weeks:

y = 51 ÷ 15

y = 3.4

So the teacher needs 3.4 lessons per week to teach 6 chapters in 15 weeks.

Find the area of the figure
VLD [36.1K]

Answer:

132 cm²

Step-by-step explanation:

Consider the shape as a trapezoid with a rectangle added on top.

The area of the trapezoid is (7+19)/2 × 8 =104

The area of the rectangle is 7×4 = 28

Add the two areas: 104+28= 132

OR consider the shape as a tall rectangle with the two triangles added to the sides.

The area of the rectangle is 7(4+8) = 84

The area of the triangles is 8(19-7)/2= 48

[Each triangle is 24 cm²]

Add those areas

84+48=132

Same result: 132 cm²

A taxpayer itemized and deducted an amount in a previous year and
saveliy_v [14]

This is not a form of income it is known as federal tax refund.

What is federal tax refund ?

Tax refunds are issued to taxpayers who have overpaid their taxes, or whose employers have withheld too much from their paychecks.

Therefore, A federal tax refund is not entered on a federal tax return so it is not income. Tax refunds from state governments can be itemized deductions on your federal tax return in the year they are issued.

It must be noted that If you electronically file your tax return or if you file a paper return, your refund is generally issued within 21 days.
