This will be your formula:
$\frac{32}{800} = \frac{120}{x}$
cross multiply (32 times x) (120 times 800)
this is what you'll get:

Find the arc length of the partial circle.

kodGreya [7K]

Answer:

Arc length of the partial circle = 3π units

Step-by-step explanation:

Given question is incomplete; please find the complete question attached.

Formula for the arc length of a circle = $\frac{\theta}{360^\circ}(2\pi r)$

Here θ is the angle formed by the sector at the center.

Angle that is formed at the center of the circle is = 360° - 90°

= 270°

So, length of the arc = $\frac{270}{360}(2\pi)(2)$

= 3π

Therefore, length of the given partial circle is 3π units.

If a loan option had been available for your food truck for the $50,000 at 4% interest for 6 years instead of 4 would you have t

stira [4]

Answer:

It depends.

Step-by-step explanation:

For 6 years:

$50000*(1.04)^6=\$63266$

On average, you would have to be profiting:

$\frac{63266}{6}=\$10544$ per year

For 4 years:

$50000*(1.04)^4=\$58492$

On average, you would have to be profiting:

$\frac{58492}{4} = \$14623$ per year.

It would be better to have the longer term option - although you will be paying off more in total, you would be paying off a smaller portion of your earnings.

However, you may want to pay off the loan faster as you would no longer have to worry about it, and it would be cheaper to pay off over the shorter period.

Please help me with these.

18. The perimeter is simply √3 + √3 + √3 + √3 or 4√3cm, since the perimeter is just all sides added together. You could add the decimal numbers together using a calculator, which I'm not sure if you're supposed to do in your class.

The area is just width times length, so √3 • √3 = 3cm².

19. The perimeter is 2√5 + 2(9 - √5).

This can also be written as 2√5 + 18 - 2√5, which leaves you with a perimeter of 18ft.

The area would be √5 • (9 - √5), which leaves you with (9√5 - 5)ft².

20. The formula for the perimeter (or circumference) of a circle is π times the diameter of the circle. Using the radius of the circle, 1/π, the diameter is 2/π, so

π • 2/π = 2. The circumference of the circle is 2 inches.

The area of the circle is calculated with the equation πr², so

π(1/π)² = π • 1/(π²) = π/(π²) = π. The area is simply π in².
