Answer:

BC≈ 14.4 to the nearest tenth.

Step-by-step explanation:

To solve this, we are going to use the cosine formula;

a² = b² + c² - 2bc cos A

a=BC and it is what we are looking for, A= 91° b=AC=13 and c=AB=6

We can now proceed and substitute the values into our formula;

a² = b² + c² - 2bc cos A

a² = 13² + 6² - 2(13)(6) cos 91

= 169 + 36 -156 cos91

=205 - 156(-0.01745)

= 205 + 2.7222

=207.7222

a² = 207.7222

Take the square root of both-side to get the value of a

√a² = √207.7222

a=BC=14.41257

BC=14.41257

BC≈ 14.4 to the nearest tenth.

How do you graph a solution set of an inequality that only has whole numbers

fomenos

Answer:

Step-by-step explanation:

A solution set is the set of values which satisfy a given inequality. It means, each and every value in the solution set will satisfy the inequality and no other value will satisfy the inequality.

Example:

Solve 2x + 3 ≤ 7, where x is a natural number.

Solution:

2x + 3 ≤ 7

Subtracting 3 from both the sides,

2x ≤ 4

Dividing both sides by 2,

x ≤ 2

Since x is a natural number,

Solution set = {1,2}.

Damerly Company (a Utah employer) wants to give a holiday bonus check of $250 to each employee. Since it wants the check amount

Marat540 [252]

Answer:

Withholding taxes

Federal income tax withheld= $100.24

OASDI tax withheld=$24.86

HI tax withheld=$5.81

Utah income tax withheld=$20.05

Gross amount= $400.96

Step-by-step explanation:

Amount per employee(desired net pay)= $250.00

Federal rate=25%=0.25

OASDI tax=6.2%=0.062

HI tax witheld= 1.45%=0.0145

Utah income tax=5%=0.05

Combined taxes= 0.25+0.062+0.0145+0.05=0.3765

Gross pay=Desired net pay/(1-all taxes)

Gross pay= 250/(1-0.3765)=250/0.6235=400.96

Working backwards

Since we have gross bonus of $400.96

Federal income tax withheld is 0.25of$400.96= $100.24

OASDI tax is 0.062of$400.96=$24.86

HI tax is 0.0145of$400.96=$5.81

Utah income tax is 0.05of$400.96=$20.05

Total deductions=$100.24+$24.86+$5.81+$20.05= $150.96

Net income is $400.96-$150.96= $250.00
