Answer:

First number: 71/7

Second number: 135/7

Third number: 270/7

Step-by-step explanation:

First number = x

Second number= 2x-1

Third number= 2(2x-1)

x+(2x-1)+2(2x-1)= 68

3x-1+4x-2=68

7x-3=68

7x=71

x=71/7

You can check by plugging in the x into the equation.

Can someone please HELP ME!!
IRISSAK [1]

Volume of a cone = PI x r^2 x h/3

Volume = PI x 5^2 x 9/3

Volume = 235.62 cubic cm.

Volume of a block of wax = L x W x H

Volume = 2 x 4 x 3 = 24 cubic cm.

Total number of blocks = Volume of cone / volume of blocks:

235.62 / 24 = 9.82

Round up to 10.

They will need 10 blocks.

Mademuasel [1]

Sales revenue will be recorded at $4,000 and yang Yang would be required to Recognize sales tax liability of $360.

What is  sales revenue?

  • The terms revenue and sales revenue are sometimes used synonymously.
  • However, the concept of revenue includes income derived from sources other than those directly connected to the primary business, such as interest on savings or money distributed as dividends.
  • Revenue comprises income derived from the sale of goods and services. The classification of this is "non-operating income."

Sales = $4,000

State sales tax rate = 9%

State sales tax = Sales x State sales tax rate

= 4,000 x 9%

= $360

Sales revenue will be recorded at $4,000 and sales revenue is not affected by the sales tax amount.

Hence, Yang would be required to Recognize sales tax liability of $360.
