The required solution in scientific notation is 2 × 10¹ .
Scientific notation can be used to indicate values that are either too large or too little to be conveniently written in decimal form (typically would result in a long string of digits).
In the UK, it is also known as standard form, scientific form, and standard index form.Because it can simplify numerous mathematical operations, this base ten notation is frequently used by scientists, mathematicians, and engineers.Scientific notation for non-zero numbers takes the form m × 10n, or m times ten raised to the power of n, where n is an integer and m is a non-zero real number.The given expression is (6.4 × 10³) ÷ (3.2 × 10²)
Simplifying we get :
(6.4 × 10³) ÷ (3.2 × 10²) = 20
This can be written in the scientific notation as : 2 × 10¹
Therefore the required solution is 2 × 10¹

One batch of cookies requires 1 3/4 cups of flour. How much flour would you need for 2/3 of a batch
The amount of flour needed for 2/3 of a batch of cookies is [tex]1\frac{1}{6}[/tex].
What are fractions?An element of a whole is a fraction. The number is represented as a quotient in mathematics, where the numerator and denominator are divided.p/q is a common way to represent fractions. They are divided into three categories: proper fractions, improper fractions, and mixed fractions depending on the numerator and the denominator.Given:
Amount of flour required for one batch of cookies = [tex]1\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]
Amount of flour needed for 2/3 of a batch of cookies = [tex]\frac{2}{3} * \frac{7}{4}[/tex] = [tex]\frac{7}{6}[/tex] = [tex]1\frac{1}{6}[/tex]
Therefore, the amount of flour required for 2/3 of a batch of cookies is [tex]1\frac{1}{6}[/tex].

Step-by-step explanation:
If a scale of a map is 1:10000 what will be the length on this map of a road which is 5 km long?
Step-by-step explanation:
1:10000
means we are using the same metric on the map and in reality.
just 1 unit in the map corresponds to 10000 units in reality.
so, e.g. 1 cm on the map = 10000 cm in reality.
1 m = 100 cm
so, 10000 cm = 100 m.
therefore, 1 cm on the map = 100 m in reality.
but we need 5 km = 5000 m.
that is 50 times 100 m in reality or 1 cm on the map.
so, the length on the map is 50 cm.

a right rectangular prism is packed with cubes of side length 1/6 inch. if the prism is packed with 12 cubes along the length, 3 cubes along the width, and 2 cubes along the height, what is the volume of the prism?
The volume of the right rectangular prism= 1/3 cubic inches
In this question, we have been given a right rectangular prism is packed with cubes of side length 1/6 inch.
We need to find the volume of the rectangular prism if the prism is packed with 12 cubes along the length, 3 cubes along the width, and 2 cubes along the height.
The length of the rectangular prism would be,
l = 12 × 1/6
l = 2 inches
The width of the rectangular prism would be,
w = 3 × 1/6
w = 1/2 inches
The height of the rectangular prism would be,
h = 2 × 1/6
h = 1/3 inches
so, the volume of the rectangular prism would be,
V = l × w × h
V = 2 × 1/2 × 1/3
V = 1/3 cubic inches
Therefore, the volume of the rectangular prism = 1/3 cubic inches

Choose by clicking the graph. Find <0 if sec0= -13/5 and tan0 is negative
Using the definition of the secant, the angle is given as follows:
θ = 112.6º.
How to calculate the secant of an angle?The secant of an angle θ is given by one divided by the cosine of the angle θ, that is:
sec(θ) = 1/cos(θ).
In the context of this problem, the numeric value of the secant of the angle is given as follows:
sec(θ) = -13/5.
This means that the following relation can be established:
1/cos(θ) = -13/5.
Hence we can solve to find the angle measure as follows, applying cross multiplication:
-13cos(θ) = 5
cos(θ) = -5/13.
Applying the inverse cosine, we have that:
θ = arccos(-5/13).
θ = 112.6º.
This angle has equivalent on other quadrants, as for example, in the third quadrant the cosine is also negative. However, in the third quadrant, the tangent is positive and we want a negative tangent, which is why the measure is of θ = 112.6º.

such that we have to sum all of the triangles that we have here
10x + 9 + 3x + 13 + x + 4 = 180
we have to take the like terms
10x + 3x + x + 9 + 13 + 4 = 180
14x + 26 = 180
14x = 180 - 26

The image of the setting sun most likely not described in great detail in "Because I Could Not Stop for Death" because it is a common symbol of death that requires little description.
Emily Dickinson's lyrical poem "Because I could not stop for Death" was originally printed in Poems: Series 1 in 1890, after her death. We don't know if Dickinson finished "Since I could not stop for Death" or if it was "abandoned" because her writing was never granted permission to be published.
In the poem "Because I could not stop for death the personified Death appears to Dickinson's poem's speaker. The poet's character speaks calmly about Death, the Afterlife, and the tranquility that comes with it. She represents Death as a young guy accompanying her in a carriage. She gives us a quick overview of her previous life while still living as she passes through to the afterlife.

We have to calculate the number of seconds for the flare to return to the sea.
We have an initial vertical speed of 448 ft/s.
The only force acting on the flare is gravity.
Then, we can model the heigth in function of time using the equation:
[tex]h(t)=h_0+v_yt-\frac{g}{2}t^2[/tex]where h0 = 0 ft, vy = 448 ft/s and g = 32 ft/s².
Then, we can replace and calculate t for h(t) = 0, that is the time it took the flare to come back to the initial height (that is 0 ft):
[tex]\begin{gathered} h(t)=0 \\ h_0+v_yt-\frac{g}{2}t^2=0 \\ 0+448t-\frac{32}{2}t^2=0 \\ 448t=16t^2 \\ 448=16t \\ t=\frac{448}{16} \\ t=28 \end{gathered}[/tex]Answer: it will take 28 seconds for the flare to return to the sea [Third option].

How to find his salary prior?An employee's pay is the amount of money that they are given each month by their employer, particularly if they work in an occupation like education, law, or medicine.
For instance, the lawyer received a big salary.
Given,
Ron Fortini received a 5.20% merit increase
2.75% cost-of-living increase
His new weekly salary is $968.80.
Solution:
Let's take his initial salary as x.
The total increase in Ron's salary = 5.20%+2.75% = 7.95%
i.e.,
107.95% * x = $968.80
107.95/100*x = 968.80
x = 968.80 * 100/107.95
x = 897.45
His weekly salary prior to the increases is $897.45.
