3 + (2 + 8)2 ÷ 4 × 1/ 2 to the power of 4

kicyunya [14]

Answer:

The answer to this is 4 and 9 over 16.

Step-by-step explanation:

The expression is 3 + (2 + 8)^2 ÷ 4 × 1 over 2 to the power of 4 . it can be represented mathematically as

3 + (2 + 8)^2 ÷ 4 × (1/2)^4

using PEMDAS

parenthesis come first

3 + 10^2 ÷ 4 × (1/2)^4

exponential comes next

3 + 100 ÷ 4 × 1/16

3 + 25 × 1/16

3 + 25/16

(48 + 25)/16

73/16

Lia brought 21 shirts and plants. Her total was $357. Pants cost $25 each, and shirts cost $14.50 each. How many of each item di

g100num [7]

Answer:

x=5 and y=16

Step-by-step explanation:

x = number of pants

y = number of shirts

Set up equations:

25x + 14.5y = 357
x + y = 21

Set the equations up as a system:

25x+14.5y=357

x+y=21

Steps:

Solve the system by substitution.

(You can also solve this system by elimination.)

Step 1: Solve x+y=21 for x:

(x + y) − y = (21) − y(Subtract y from both sides)

x = −y + 21

Step 2: Substitute −y + 21 for x in 25x + 14.5y = 357:

25x + 14.5y = 357

25(−y + 21) + 14.5y = 357

−10.5y + 525 = 357 (Simplify both sides of the equation)

(−10.5y + 525) − 525 = (357) − 525(Subtract 525 to both sides)

−10.5y = −168

−10.5y / −10.5 = −168 / −10.5 (Divide both sides by -10.5)

y = 16

Step 3: Substitute 16 for y in x = −y + 21:

x = −y + 21

x = −16 + 21

x = 5 (Simplify both sides of the equation)

Answer:

x=5 and y=16

Griffin's Goat Farm, Inc., has sales of $671,000, costs of $333,000, depreciation expense of $77,000, interest expense of $48,50

Alchen [17]

Net income for the firm = $161,500

Step-by-step explanation:

Step 1 :

Total sales of the goat farm = $671,000

Cost incurred = $333,000

Depreciation expense = $77,000

Interest expense = $48,500

We need to compute the net income of the firm

Step 2 :

The profit before tax can be computed by subtracting all the expenses from the sale.

Total expenses of the firm = 333,000 + 77,000+ 48,500 = $458,500

Profit before tax = 671,000 - 458,500 = $212,500

Step 3 :

Percentage of tax for the firm = 24%

Amount of tax for the firm = 24% of 212500 = 51000

Net income = Total profit after tax = 212500 - 51000 = 161,500

Step 4 :

Answer :

Net income for the firm = $161,500
