Zielflug [23.3K]

Answer:

2 and 2/5 candy bars

Step-by-step explanation:

To figure this out, simply add the fractions together 6 times or multiply 2/5 by 6.

(2/5)(6/1)

Multiply the numerator

2*6=12

Multiply the denominator

5*1=5

so the answer is 12/5 or 2 and 2/5 candy bars.

Answer:

The center of the circle is (13.4, - 2.6).

Step-by-step explanation:

Circle:

The diameter of a circle is 2 times of its radius.
The area of a circle is $\pi r^2$ , where is the radius of the circle.

The circumference of a circle is $2\pi r$ , where r is radius of the circle.

We know that,the equation of circle is in the form

$(x-\alpha)^2+(y-\beta)^2= r^2$

where $(\alpha, \beta)$ is the center of the circle and r is the radius of the circle.

Given equation of circle is

$(x-13.4)^2+(y+2.6)^2=100$

The center of the circle is (13.4, - 2.6).

The radius of the given circle is $\sqrt{100}$ units=10 units.

Which of the following expressions does not equal: the sixth root of 81x^4y^8

DerKrebs [107]

$\sqrt[6]{81x^4y^8}=\left[3^4x^4(y^2)^4\right]^\frac{1}{6}=\left[\left(3xy^2\right)^4\right]^\frac{1}{6}\\\\=\left(3xy^2\right)^{4\cdot\frac{1}{6}}=\left(3xy^2\right)^\frac{2}{3}\to A\\\\=\left(3xy^2\right)^\frac{2}{3}=\sqrt[3]{\left(3xy^2\right)^2}=\sqrt[3]{9x^2y^4}\to D\\\\=\left(3xy^2\right)^\frac{2}{3}=\left(3x\right)^\frac{2}{3}y^{2\cdot\frac{2}{3}}=\left(3x\right)^\frac{2}{3}y^\frac{4}{3}\to B\\\\\\Answer:C$
