Answer: A

Step-by-step explanation:

When you write exponential form to radical form, the fraction tells us that kind of root it is. Since it is a cubed root, as indicated by the 3 in front of the radical, we know that the fraction will be $\frac{1}{3}$ . If it were to be $\frac{1}{3}$ , the entire radical would be to the power of 1. Since the radical is to the power of x, our answer would be $125^{\frac{1}{3}x }$ .

Write and solve a real-world problem that can be modeled by the equation 0.75 - 18.50 = 0.65x

jenyasd209 [6]

Answer:

Step-by-step explanation:

Sam bought a chocolate. He ate some and leaving 0.75 for Alice.

Alice ate 18.50 grams of chocolate and return the rest to Sam, which was 65% of the original chocolate. How much chocolate did Sam had at the beginning?

Now solve the equation:

0.75x - 18.50 = 0.65x

Combine the like terms:

0.75-0.65x = 18.50

0.1x= 18.50

x = 18.50/0.1

x=185

This shows that Sam had 185 grams of chocolate...

n200080 [17]

Question:

What is the area of the sector? Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal rounded to the nearest hundredth.

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the values of radius and central angle are not given.

However, I'll answer the question using the attached figure.

From the attached figure, the radius is 3 unit and the central angle is 120 degrees

The area of a sector is calculated as thus;

$Area = \frac{\alpha }{360} * \pi r^2$

Where $\alpha$ represents the central angle and r represents the radius

By substituting $\alpha = 120$ and r = 3

$Area = \frac{\alpha }{360} * \pi r^2$ becomes

$Area = \frac{120}{360} * \pi * 3^2$

$Area = \frac{1}{3} * \pi * 9$

$Area = \pi * 3$

$Area = 3\pi$ square units

Solving further to leave answer as a decimal; we have to substitute 3.14 for $\pi$

So, $Area = 3\pi$ becomes

$Area = 3 * 3.14$

$Area = 9.42$ square units

Hence, the area of the sector in the attached figure is $3\pi$ or 9.42 square units
