7 0

Answer:

Option (1)

Step-by-step explanation:

Given:

CF ≅ DF

CE ≅ DE

To prove:

ΔCFE ≅ ΔDFE

Solution:

From ΔCFE and ΔDFE,

               Statements                             Reasons

1). CF ≅ DF                                  1). Given

2). CE ≅ DE                                2). Given

3). FE ≅ FE                                 3). Reflexive property

4). ΔCFE ≅ ΔDFE                       4). By SSS property of congruence

Therefore, SSS postulate of congruence will be the answer.

Option (1) will be the answer.

Find the inverse of f(x)=−3/2x+7/2.
timama [110]

Answer: f^{-1}(x)=-\frac{2}{3}x+\frac{7}{3}

Step-by-step explanation:

To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.

y=-\frac{3}{2}x+\frac{7}{2}                       [replace y with x and x with y]

x=-\frac{3}{2}y+\frac{7}{2}                       [subtract both sides by 7/2]

x-\frac{7}{2} =-\frac{3}{2}y                       [multiply both sides by -2/3]

-\frac{2}{3} (x-\frac{7}{2} )=y                     [distribute]

y=-\frac{2}{3}x+\frac{7}{3}

Now, we have our inverse function.

f^-^1(x)=-\frac{2}{3}x+\frac{7}{3}

If a stadium pays $11000 for labor and $7000 for parking what would the stadiums parking revenue be if the stadium is hoping par
Alchen [17]

Answer:

$300,000

Step-by-step explanation:

Labor  cost = $11,000

Parking  cost= $7,000

Parking Labor cost = $ 18,000

Parking Revenue = ?

From the question, parking labor cost is 6% of Parking revenue.

6% =   Parking Labor cost/ Parking Revenue------------------------------------ (1)

Further substituting in (1) gives:

6/100  =  18,000/ Parking Revenue

Making Parking Revenue the subject of the formula, we have:

Parking Revenue = (100 x 18,000)/6

                             = $300,000
