Answer:

Area of circle = 9<em>π</em>

Step-by-step explanation:

Area of sector = \frac{1}{2} \pi

Its central angle = \frac{1}{9}\pi \text{ radians}

\text{Area of sector} = \dfrac{\text{Central angle}}{2\pi} \times\text{Area of circle}

\text{Area of circle} = \text{Area of sector}\times\dfrac{2\pi}{\text{Central angle}}

A = \dfrac{1}{2}\pi\times\dfrac{2\pi}{\frac{1}{9}\pi} = 9\pi

joes family has compleated 60% of a road trip. if they have traveld 30 miles, how far is the full road trip?
Tems11 [23]

The full road trip is 50 miles.

Step-by-step explanation:

Given,

Distance traveled by Joe's family = 30 miles

This represents 60% of the total distance to be traveled.

Let,

x be the total distance.

60% of x = 30

\frac{60}{100}*x=30\\0.6x=30

Dividing both sides by 0.6

\frac{0.6x}{0.6}=\frac{30}{0.6}\\x=50\ miles

The full road trip is 50 miles.

Use the ruler to find 1 / 1/10 and 4 1/10
Korvikt [17]

Answer:

the first answer is 10 and the second is 40

Step-by-step explanation:

there actually asking how many meters would make 1 centimeter

On the ruler 1 whole centimeter is 10 meter. (The longer line behind the number is the 10th meter )

Dividing fractions

1 ÷ 1/10

Steps

Change the whole number which is 1 into a fraction.

1/1 ÷1/10

Flip the second fraction in the equation.

1/1 ÷ 10/1

Then change the division sign to a multiplication sign. So were multiply instead.

1/1 × 10/1

Multiply the fractions and your answer should be 10/1 .

This fraction is also changed to a whole number.

10/1 = 10

Simplify (x^14)^3 <br><br> ffffffffffffffffffffffffffffff
Salsk061 [2.6K]

Answer:

(x^{14}) ^{3} = x^{42}

Step-by-step explanation:

In this case in order to simplify we need to know what the "power rule of exponents" is. Simply speaking this rule states that when you raise a power to  a power you multiply the exponents. So in our case we ill get the following

(x^{14}) ^{3} = x^{42}

In order to get 42 we used the power rule which I mentioned earlier.
