If you would like to solve 2 1/2 divided by 1 5/8, you can calculate this using the following steps:

2 1/2 / 1 5/8 = 5/2 / 13/8 = 5/2 * 8/13 = 20/13 = 1 7/13

The correct result would be C. 1 and 7/13.

In how many ways can a family of four be seated at a round table if two brothers must sit together?

Masteriza [31]

The 4-member family can be seated in 4! ways.
The two brothers can be seated together in 2! ways.

Therefore, the total number of ways is
$\frac{4!}{2!} = \frac{4.3.2.1}{2.1} =4*3=12$

Diagrammatically, the result is shown in the figure below. The two brothers are family members 3 and 4, shown in shaded color.

Answer: 12 ways.

Which rule describes the composition of transformations that maps ΔJKL to ΔJ"K"L"?

Vera_Pavlovna [14]

The rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.

<h3>What is the transformations rule that was used here?</h3>

A transformation is a rule that is used to manipulate the position of a point of geometric figure.

Analyzing the figure, rotation of ΔJKL through the angle 90 degrees in a counter-clockwise direction gives us ΔJ'K'L' .

ΔJ"K"L" is been gotten also using ΔJ'K'L' through the refraction of ΔJ'K'L' across the x-axis.

In this case, rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.

If a function is symmetric over the line x = 2, what kind of function could it be? A. absolute value B. cubic C. exponential D.

Anon25 [30]

Answer:

A. Absolute value.

Step-by-step explanation:

We are asked to determine the type of function, if it is symmetric over the line $x=2$ .

We know that a line of form $x=a$ represents an equation of a vertical line that crosses x-axis at point $(2,0)$ parallel to y-axis.

We know that a cubic function is symmetric about origin, while an exponential function has no symmetry.

A rational function is not necessarily symmetric to y-axis.

We know that an absolute value function is symmetric about y-axis, so our given function will be symmetric to the line $x=2$ and option A is the correct choice.

WILL MARK BRANIEST: If the magnitude of the block's acceleration is 1.5 m/s2, what is the mass of the block? Show your work. (Th

puteri [66]

Answer:Answer:

F = 0.84 [N]

Explanation:

In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.

F = m*a

where:

F = force [N]

a = acceleration = 1.4[m/s^2]

m = mass = 0.6 [kg]

F = 0.6*1.4

F = 0.84 [N]
