A= \frac{1}{2} h (x+y)

we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side

So

A= \frac{1}{2} h (x+y)

Multiply both sides by 2

2A = h(x+y)

Divide both sides by h

2A/h = x+y

Subtract y from both sides

\frac{2A}{h}  -y =x

or

x=\frac{2A}{h}  -y

velikii [3]

Answer:

M = 1/0.000121 = 8264.5 years

Step-by-step explanation:

M = − k ∫∞₀ teᵏᵗdt

To obtain this mean life, we'll use integration by parts to integrate the function ∫ teᵏᵗdt

∫udv = uv - ∫ vdu

u = t

du/dt = 1

du = dt

∫ dv = ∫ eᵏᵗdt

v = eᵏᵗ/k

∫udv = ∫ teᵏᵗdt

uv = teᵏᵗ/k

∫ vdu = eᵏᵗ/k

∫ teᵏᵗdt = (teᵏᵗ/k) - ∫eᵏᵗ/k

But, ∫eᵏᵗ/k = (1/k) ∫eᵏᵗ = (1/k²) eᵏᵗ = eᵏᵗ/k²

∫ teᵏᵗdt = (teᵏᵗ/k) - eᵏᵗ/k²

The rest of the calculation is done on paper in the image attached to this question

Dmitriy789 [7]

Answer:

$2368.75

Step-by-step explanation:

Kedar earns a monthly salary of $2200 and a commission of 3.75%

He sold $4500 this month

The first step is to calculate his commission for this month

His commission can be calculated as follows

= 4500 × 3.75/100

= 4500 × 0.0375

= 168.75

Therefore yr amount earned this month can be calculated as follows

= 2200 + 168.75

= $2368.75

s2008m [1.1K]
First lets remove the initial fee
190 - 40 = 150
150 is how much she is charging you per hour.
If each hour is 55, lets divide 150 by 55.
150 \div 55 = 2.7
She charged you for 2.7 hours (almost 3) of service
