Answer:

\large\boxed{r=\dfrac{3A-hb}{h}}

Step-by-step explanation:

A=\dfrac{1}{3}h(r+b)\qquad\text{multiply both sides by 3}\\\\3A=h(r+b)\qquad\text{use distributive property}\\\\3A=hr+hb\qquad\text{subtract hb from both sides}\\\\3A-hb=hr\qquad\text{divide both sides by }\ h\neq0\\\\\dfrac{3A-hb}{h}=r

vaieri [72.5K]

Answer:

y = 9 - 1.75x

Step-by-step explanation:

Given

Initial\ Height = 9ft

Rate = 1.75ft per hour

Required:

Determine the linear function

Let y represent the function and x represent the number of hours

The function can be represented with:

y = Initial\ Height- Rate * x

We used minus (-) in the equation because the question indicates that the height of the sculpture reduces.

So, we have:

y = 9 - 1.75 * x

y = 9 - 1.75x

Nostrana [21]

Answer:

5.73 years

Step-by-step explanation:

Considering she saved 4.25% in each year of the amount $15000.

So, we have to calculate in what time her saving reaches $1275, if she save each year.

it becomes question of simple interest in which

SI = $1275, Principal P= $5000, time T, rate R = 4.25%

we know SI = PRT/100

1275 = 5000×4.25×T/100

⇒T = 1275×100/(5000×4.25)

⇒ T= 5.73 years
