Answer:

a = 76/3

Step-by-step explanation:

I completely understand your frustration. Algebra 2 is also painful for me this year.

1. Since these equations are equal to each other, you can cross multiply them and set those equal to each other: (a -12) • 3 = 4 • 10.

2. Solve: (a-12) • 3 = 4•10

3a-36 = 40

3a=76

a= 76/3.

(Is this supposed to be a whole number?)

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

Sati [7]

Answer:

2.5m

Step-by-step explanation:

Using the adjusted accounting profits method.

Operating cash flow = After - tax profit + Depreciation. .......... ( 1 )

Given that :

* depreciation expense = $1 million

* Sales generated $7 million

* Tax rate = 25%

Tax rate = 25/100

= 0.25

From equation 1

= ( 7m - 4m - 1m ) ×( 1 - 0.25 ). + 1m

= ( 7m - 5m ) × ( 0.75 ) + 1m

= 2m × 0.75 + 1m

= 1.5m + 1m

= 2.5m

The firm operating cash flow = 2.5m
