An accountant needs to withhold 18% of income for taxes if the income is below $40,000, and 27% of income if the income is $40,0
ser-zykov [4K]

Answer:

=IF(A1<40000,(18%*I18),(27%*A1))

Step-by-step explanation:

The spreadsheet expression to  be used is the "IF" function. The "IF" function is one that returns a value based on the conditions stated thereafter in the spreadsheet formula. Like every spreadsheet function, this also starts with =

In the question given,

The value to be examined is in cell A1. if A1 is less than $40000 is written as A1<40000, is true,  the spreadsheets executes the next function stated as  (18%*I18) otherwise (which in this case can be interpreted as A1 greater than or equal to $40000), compute the next command as shown above;  (27%*A1)

The final parenthesis closes the command.

Hence the expression is IF(A1<40000,(18%*I18),(27%*A1)).

Quadrilateral ABCD is inscribed in a circle. What’s the measure of angle B
wariber [46]
Well the equation is 6x + x + 19 = 180 or 7x + 19 = 180. You subtract 19 from 180 to get 161. Then you divide 161 by 7 to get x = 23. Finally, you plug x in to get 6(23) + 19 or 157°

What is the value of y? NU=9, NM= 3, MT= 6, TN= y
nevsk [136]

Answer:

6\sqrt{3}

Step-by-step explanation:

We have to use Pythagoras' identity twice to find y

The square on the hypotenuse is equal to the sum of the squares on the other two sides.

In right triangle MUT to find TU

TU² + 3² = 6², that is

TU² + 9 = 36 ( subtract 9 from both sides )

TU = 27 ( take the square root of both sides )

TU = \sqrt{27} = \sqrt{9(3)} = 3\sqrt{3}

In right triangle NUT to find y

y² = 9² + (3\sqrt{3} )² = 81 + 27 = 108 ( take the square root of both sides )

y = \sqrt{108} = \sqrt{36(3)} = 6\sqrt{3}
