Calculate the quotient below and give your answer in scientific notation.
2.64*10^-3\8.0*10^0
Answer:
The quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]
Step-by-step explanation:
We need to find quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex]
We know that [tex]10^0=1[/tex]
Now solving:
[tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033[/tex]
Writing it in scientific notation
[tex]0.00033\\=3.3\times10^{-4}[/tex]
So, the quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]

There are markings given in the diagram.
(Angle) ∠A and ∠D are =
(Side) AC and DB are =
(Side) In a trapezium, the opposite sides are equivalent, meaning AB and DC are =
So you got side, angle, and another side.
You can form the SAS (Side-Angle-Side) similarity theorem.
You can also use the reasons above to make a Statement-Proof table
Find the value of that makes m ll n.
Answer: x = 108
Step-by-step explanation: In this problem, we're given a diagram and
we're asked to find the value of x that would make m ll n.
We can see that the angles that are marked in the diagram
are same-side interior angles since they lie on the same side
of the transversal and they lie on the interior of lines m and n.
Therefore, in order for line m to be parallel to line n,
these angles must be supplementary.
In other words, they must add to 180 degrees.
So we can setup the equation x + 72 = 180.
Subtracting 72 from both sides gives us x = 108.
So the value of x that would make line m ll n is 108.
Expand and combine like terms. (3-8w^2)^2
Answer:
64w^4 - 48w^2 + 9
Step-by-step explanation:
(I rearranged the terms so I could solve it easier)
Expanding the square:
(-8w^2 + 3)^2
(-8w^2 + 3)(-8w^2 + 3)
Combining like terms:
64w^4 - 24w^2 - 24w^2 + 9
64w^4 - 48w^2 + 9
Final answer: 64w^4 - 48w^2 + 9

(0, -2) and (1, 1) both work in this system of equations.
Step-by-step explanation:
Happy to help! The best way to find if it is a solution is to look for those points on the graph. When we graph the point, it needs to fall in an area where both lines or shaded or on a solid line.
Look carefully and see if you can find points like these!
(0, -2) falls on a solid line.
(1, 1) falls in the double shaded area.
Therefore, (0, -2) and (1, 1) both work in this system of equations.

10676 rounded to the nearest 100
The rounding number of 10676 nearest 100 is 10,700.
What is Rounding number?
To making a number simpler but keeping its value close to what it was, is called Rounding.
Given that;
The number is 10,676
Now, To round the number nearest to the 100 , we check the tens digit ,if the digit is equal to 5 or more then round up, and if the number is less than 5 then its round down.
Here, In the number 10,676 the digit in the tens place is 7 which is more than 5, so we can round up.
Hence, The rounding number = 10,700
Thus, The rounding number of 10676 nearest 100 is 10,700.

The population density of the world is calculated by finding the ratio of the total number of people in the world to the area of land. Since the earth is about 1.5 x 108 square kilometers, approximately how many people would inhabit each square kilometer of the earth? Show the work and / or explain your reason
Answer:
51
Step-by-step explanation:
A = Surface area of the Earth = [tex]1.5\times 10^8\ \text{km}^2[/tex]
Total number of people on Earth = 7.594 billion as of 2018 = [tex]7.594\times 10^9[/tex]
We need to find the number of people living in each square km of land area.
So, we need to divide the number of people by the land area of the Earth.
[tex]1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}[/tex]
[tex]\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}[/tex]
[tex]\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}[/tex]
So, 51 people will inhabit each square km of land area.
Q2. At a pizzeria, a plain slice of pizza costs $1.75, and each additional
topping costs $0.75. Jared buys a slice of pizza for a total cost of $4.00.
Which equation could be used to determine how many additional toppings
Jared had on his pizza? Let x = the number of toppings.
1.75x + 0.75 = 4
1.75 -0.75x = 4
1.75x -0.75 = 4
1.75 +0.75x = 4
Answer:
1.75+0.75x=4
Step-by-step explanation:
$1.75 is the set price, and you add $0.75 for every topping.

The discount allowed in a store for a cash payment is 6%. Find what a buyer pays for an article whose marked prices $567.50
Answer:
A buyer would have to pay $533.45 for an article whose marked prices $567.50.
Step-by-step explanation:
Marked price = $567.50
Discount=6%
Price after discount = 567.50 - 6% of 567.50
[tex]=\:567.50\:-\frac{6}{100}\:\times \:567.50[/tex]
[tex]=567.5-34.05[/tex]
[tex]=533.45[/tex] $
Therefore, a buyer would have to pay $533.45 for an article whose marked prices $567.50.

P(A and D) = [?]
===============================================
Explanation:
Highlight the path that starts with A and then leads to D
Multiply the values highlighted to get 0.5*0.6 = 0.3
Effectively we've computed the following
P(A and D) = P(A)*P(D given A)
P(A and D) = 0.5*0.6
P(A and D) = 0.3
The notation "D given A" indicates we know event A has happened. We cannot simply say P(D) because there is another event D that happens on the lower branch B; so instead we say P(D given A). You can replace the word "given" with a vertical bar to write P(D | A), though in my opinion the vertical bar could be easily mistaken for the uppercase letter i, a lowercase letter L, or the numeric digit "one". I find its easier to describe what is going on rather than use the vertical bar notation.

This figure is made from a part of a square and a part of a circle.
What is the perimeter of this figure, to the nearest unit? ______ units
Answer:
38 units (rounded off to the nearest unit)
Step-by-step explanation:
Find the perimeter of the circle part, if the circle section is a 90degree slice, then it is a quarter of the full circle's circumference[tex]Circumference=pi\times 2radius\\C=\pi \times 2(5)\\C=10\pi[/tex] now find a quarter of this then[tex]SectionCircumference=\frac{5}{2}\pi[/tex] Then find the perimeter of the whole thing by adding the side [tex]P=10+10+5+5+\frac{5}{2}\pi =37.85[/tex]The perimeter of the given figure will be 38 units.
What is perimeter?Its the sum of length of the sides used to made the given figure.
We are given that Measures of three linear sides as 5, 10, 10, 5 units.
Radius of the circular part = 5 units
Since Perimeter of a polygon = Measure of the circumference of the polygon
The Perimeter of the figure = measure of the three straight lines + measure of the circumference of the quarter circle
Thus Measure of linear sides = 5 + 10 + 10 + 5 = 30 units
Circumference of the quarter circle = 2πr
= 2π(5)
= 7.85 units
Perimeter of the figure = 30 + 7.85
= 37.85
≈ 38 units
Therefore, the perimeter will be 38 units.

Answer:
[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)[/tex]
Step-by-step explanation:
To see which equations have the slope of 3/4, we just need to focus on the right half of the equations to see what the multiplier of x is.
Equations 1 and 3 can be eliminated because they have a slope of [tex]\frac{1}{3}[/tex] and 4 respectively.
Now we can decide between 2 and 4 by plugging in the point [tex](4,\frac{1}{3})[/tex] to see which works properly.
Simplify equation 2
[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)\\\\y-\frac{1}{3} =\frac{3}{4}x-3\\\\y=\frac{3}{4}x-\frac{8}{3}[/tex]
Plug in the point
[tex]\frac{1}{3} =\frac{3}{4}(4)-\frac{8}{3} \\ \\\frac{1}{3} =3-\frac{8}{3} \\\\\frac{1}{3} =\frac{9}{3} -\frac{8}{3} \\\\\frac{1}{3} = \frac{1}{3}[/tex]
This checks out, so equation 2 is your answer.
