$\frac{3}4$ of $540$ is $\frac{3\cdot540}4=405$ miles. Those will hence be traveled in $\frac{405}{45}=\boxed{9\text{ hours}}$

A semi-circular garden has an area of 18pie m2 what is the perimeter of the garden

nataly862011 [7]

Answer:

6 $\pi$

Step-by-step explanation:

We know that the area of a circle is equal to $\pi$ $r^{2}$ .

A semi-circle is a half-circle, meaning that it will have half of the area of a full circle.

Therefore, a semi-circle's area is equivalent to $\frac{\pi r^{2} }{2}$ .

Set this equation equal to 18 $\pi$ .

Solve for r.

We then find that r = 6.

Now, we need to find the circumference. We know that the equation for the circumference of a circle is 2 $\pi$ r. Since we only need the perimeter of half of a circle, our circumference equation will equal $\pi$ r.

Plug 6 in for r.

The perimeter of the garden is equal to 6 $\pi$ .

A sketch artist sells on demand portraits and name doodles at the state fair. The artist has a personal maximum of 40 creations

MakcuM [25]

Answer:

profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600

Step-by-step explanation:

we have to maximize the following equation:

$10P + $20D

where:

P = number of portraits

D = number of doodles

the constraints are:

P + D ≤ 40

P ≤ 30

D ≤ 20

we do not need to use solver or any other type of linear programming tool to solve this, since profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600
