Expression simply refers to the mathematical statements which have at least two terms that are related by an operator and contain either numbers, variables, or both

In this case, the number remaining for 19.35 to get to 25 will be:

= New number - Old number

= 25 - 19.35

= 5.65

The number is 5.65.

For what values of x is the quantity x-7

Andreas93 [3]

positive = greater than 0.

Therefore we have the inequality:

$x-7 > 0$ |add 7 to both sides

$x > 7$

A circle has a sector with area 33 pi and a central angle of 11/6 pi radians. What is the area of a circle?

Mashutka [201]

Answer:

36π

Step-by-step explanation:

The area of a circle is given as:

$A = \pi r^2$

where r = radius of the circle

The area of a sector of a circle is given as:

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

where α = central angle in radians

Since $\pi r^2$ is the area of a circle, A, this implies that:

$A_s = \frac{\alpha }{360} * A$

A circle has a sector with area 33 pi and a central angle of 11/6 pi radians.

Therefore, the area of the circle, A, is:

$33 \pi = \frac{\frac{11 \pi}{6} }{2 \pi} * A\\\\33\pi = \frac{11}{12} * A\\\\=> A = \frac{33\pi * 12}{11}\\ \\A = \frac{396 \pi}{11} \\\\A = 36\pi$

The area of the circle is 36π.
