Answer:

Option C

The length of RT is 14

Step-by-step explanation:

For a given Right Triangle

m∠R = 90°, RG = 17, TG = 22

Now, <u>By Pythagoras Theorem</u>

(RT)² + (RG)² = (TG)²

(RT)² = (TG)² - (RG)²

(RT)² = (22)² - (17)²

(RT)² = 484 - 289

(RT)² = 195

RT = √195

RT = √195 = 13.96 = 14

Thus, The length of RT is 14

If there is a discount of 40% on an article costing #7000, then the price after discount is

sergejj [24]

Answer:

<h3>The answer is # 4200</h3>

Step-by-step explanation:

A discount of 40% was allowed on the price

To find the price after the discount first calculate the discount and subtract it from the original price

That's

$\frac{40}{100} \times 7000$

= 2800

So the price after the discount is

#7000 - #2800

Which is

Michael Miller is paid twice a month and had total gross earnings as of 10/15 of $116,800. His gross earnings for the period end

iogann1982 [59]

Answer:

Medicare tax to be paid by Michael =$0

Medicare tax to be paid by the employer = $1780.6

Step-by-step explanation:

Total gross earnings as of 10/15 = $116800

Gross earnings for the period ending 10/31 = $6000

Since Michael Miller is paid twice a month, the gross earnings for the period ending 10/15 = $6000

Gross earnings for the month of October = 6000+6000

= $12000

Total gross earnings as of 10/31 = 116800 + 6000

= $122800

Security tax rate = 6.25%

So, security tax to be paid by Michael = 6.25% of 122800

= $\frac{6.25}{100}$ *122800

= 0.0625*122800

= $7675

Earnings of Michael after deducting the security tax= 122800 - 7675

= $115125

The medicare tax rate will be 1.45% on $122,700 earning or more.

As Michael's earning after the payment of security tax is $115125, so Michael does not need to pay any medicare tax.

So, Medicare tax to be paid by Michael =$0

Medicare tax to be paid by the employer = 1.45% of 122,800

= $\frac{1.45}{100}$ *122800

= 0.0145*122800

= $1780.6

A 1125 ft^3 open-top rectangular tank with a square base x ft on a side and y ft deep is to be built with its top lush with the

nikdorinn [45]

Answer:

The values of x and y that will minimize the cost is 15 ft and 5 ft respectively and the minimum cost will 3,375

Step-by-step explanation:

With a 1125 ft^3 open-top rectangular tank with a square base x ft on a side and y ft deep is to be built with its top lush with the ground to catch runoff water, x is the length, y is the height;

x^2*y = 1125

y = 1125/x^2 ----(1)

The total cost of c = 5(x^2 + 4xy) + 10xy

Then,

c = 5(x^2 + 4x*(1125/x^2)} + 10x*(1125/x^2)

c = 5x^2 + 22,500/x + 11,250/x

c = 5x^2 + 33,750/x

To minimize the cost of c, find the derivatives of c; c'

c' = 10x - 33,750/x^2

c' = (10x^3 - 33,750)/x^2

c'(x) = 0; 10x^3 = 33,750

x = ³√33,750 = 15

x = 15; y = 1125/x^2

y = 1125/15^2 = 5

(x,y) = (15,5)

c = 5x^2 + 33,750/x

c = 5*15^2 + 33,750/15 = 3,375

The values of x and y that will minimize it is 15 ft and 5 ft respectively and the minimum cost will 3,375
