jeka57 [31]

Answer:

$h = \sqrt{72}in$

Step-by-step explanation:

We have a right triangle with long side of 11in and smaller sides 14in/2=7in and h.

We know that

$h^2 + (7in)^2 = (11in)^2\\h^2 = 121in^2 - 49in^2 = 72in^2\\h = \sqrt{72}in$

Solve. 9(x+1)=4-2(9x+5)

Sindrei [870]

Answer:

-5/9

Step-by-step explanation:

9(x+1)=4-2(9x+5)

Distribute

9x+9=4-18x-10

Add 4 and -10

9x+9=-6-18x

Move -18 to the left side and change sign

9x+9+18x=-6

Move 9 over and change sign

9x+18x=-6-9

Combine like terms

27x=-15

Divide both sides by 27

X=-5/9

The original cost of Sam’s investment is $10,000. After liquidating the investment, Sam calculated his real return to be $10,700

OverLord2011 [107]

Answer:

Return on investment (ROI) = 7%

Step-by-step explanation:

Given:

Amount invested = $10,000

Total amount get (refund) = $10,700

Find:

Return on investment (ROI) = ?

Computation:

Amount Return = Total amount get (refund) - Amount invested

Amount Return = $10,700 - $10,000

Amount Return = $700

$Return\ on\ investment \ (ROI) = [\frac{Amount\ Return}{Amount\ invested} ]100\\\\Return\ on\ investment \ (ROI) = [\frac{700}{10,000} ]100 \\\\ Return\ on\ investment \ (ROI) =7$

Return on investment (ROI) = 7%

What is the equation of the line in standard form?<br> 3x−y=−6 3x + y = 6 x + 6y = 9 x−6y=−9

lisabon 2012 [21]

The standard form: Ax + By = C

3x - y = -6 YES - A = 3, B = -1, C = -6

3x + y = 6 YES - A = 3, B = 1, C = 6

x + 6y = 9 YES - A = 1, B = 6, C = 9

x - 6y = -9 YES - A = 1, B = -6, C = -9
