78/9, √45 ,  ³√97 is the order of numbers from greatest to least.

Given,

The numbers;

³√97, 78/9, √45

We have to order these numbers from greatest to least.

Ordering of numbers;

A series of numbers can be arranged in numerical order. Both ascending and descending orders are possible. For instance, suppose you arranged a group of numbers in ascending order as 2, 55, 103, 256, and 802, for instance. This can make it much simpler to look through a large collection of numbers.

Here,

First we have to find the values of the numbers.

The value of ³√97 = 4.59

The value of 78/9 = 8.66

The value of  √45 = 6.71

So,

The greatest one is 78/9 and the least one is ³√97

Therefore,

The order of numbers from greatest to least is 78/9, √45 ,  ³√97

Answer:

The function that represents g(x), a reflection of f(x) = 4(one-half) Superscript x across the x-axis, is g(x) = −4(one-half) Superscript x. This function is obtained by negating the exponent of the original function, which reverses the direction of the exponential growth and creates a mirror image of the original function across the x-axis. The other options listed do not correctly reflect the original function across the x-axis.

The rent of the gym for one hour is $50 and for three hours it is $100.

It is the basic arithmetic operation, in which you are separating the number into some parts. One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components.

Given:

A recreation center charges $50 to rent the gym for 1 hour, and $100 to rent the gym for 3 hours,

Calculate the price if you rent a gym for 3 hrs = 100 / 3 = $33.33

Therefore, the rent of the gym for one hour is $50 and for three hours it is $100.

Step-by-step explanation:

(A) only 2 is the line of symmetry of the given figure.

A form or item is divided into two equal and symmetrical portions by a line of symmetry.

Because it divides the figure symmetrically and the separated portions resemble mirror images of one another, we also refer to this line as the axis of symmetry or the mirror line.

The four lines of symmetry in a square are lines across the opposing vertices and the midpoints of the opposing sides.

Together, these four lines of symmetry make up a square.

Consequently, a square has two diagonal, one horizontal, and one vertical line of symmetry.

So, according to the given figure we can easily observe and tell that line 2 is the only one that divides the diagram into 2 identical parts.

Therefore, (A) only 2 is the line of symmetry of the given figure.

By the concept of the sum of the adjacent angle in a parallelogram, we determine m∠PQR = 76°.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

We know a parallelogram has opposite angles of equal measure and the sum of adjacent angles is 180°.

Given, m∠QRP = 38° and m∠PRS = 66°.

∴ m∠PQR = 180° - 38° - 66°.

Answer:

  20%

Step-by-step explanation:

You want to know the percentage error in an estimate of 1.8 L for an actual value of 1.5 L.

The percentage error is the ratio of error amount to actual value, multiplied by 100%.

  Error amount = estimate - actual = 1.8 L -1.5 L = 0.3 L

  ratio = (error amount)/(actual) = (0.3 L)/(1.5 L) = 0.2

  percentage error = 0.2 × 100% = 20%

The error in the student's estimate is 20%.

b = 2

Step-by-step explanation:

because of the 60° in the corner we know this triangle is the left half of an equilateral triangle (where all 3 sides are equally long, and all 3 angles are 60°).

therefore, b is half of the baseline of that equilateral triangle = 4/2 = 2.

so, b = 2 is the correct answer.

Answer:

$4.00

Step-by-step explanation:

There is, in total, 4 people attending the movies. [Zack and his 3 friends]

If each ticket costs $8.00, we can use 4 x $8.00 to find out how much the tickets costs.

4 x $8.00 = $32.00

If his mom paid $48 dollars in total, to get the amount of money they spent on snacks, we can use $48 - $32.

$48 - 32 = $16

We can now divide $16.00 by 4, as everyone [Zack and his 3 friends] got the same snack from the concession stand, and that leaves us with the equation: $16/4 [also known as 16 divided by 4]

$16/4 = $4.00
