The length of a planet's orbit around a star is approximately 16,540,000 km.
It takes the planet about 710 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf? ANSWER PLS 15 POINT UP FOR GRABS
Answers
Answer:
971 km/h
Step-by-step explanation:
The length of a planet's orbit around a star is approximately 16,540,000 km and it takes the planet about 710 Earth days to complete a full orbit.
Average speed is given as total distance traveled divided by time taken. That is:
S = D / t
Where t is in hours.
We have to convert 710 days to hours:
1 day = 24 hrs
710 days = 710 * 24 = 17040 hours
Therefore, the planet's speed is:
S = 16540000 / 17040 = 971 km/h (to 3 sf)

At a financial conference, the 750 attendees were given the choice of turkey, ham, both, or neither on the sandwich in their sack lunch. Eighty-five of the attendees chose neither and 200 chose both. If a total of 400 people had ham on their sandwiches, use the Venn diagram below to determine how many people had only turkey on their sandwich.
750
665
350
265
Answers
Answer:
265
Step-by-step explanation:
All values should add up to 750
85 + 400 + x = 750
485 + x = 750
x = 265
Number of people had only turkey on their sandwich from the given Venn diagram is equals to 265.
What is Venn diagram?
" Venn diagram is defined as pictorial representation of set of data using circles and rectangle in logical form to represent the relation between the given sets."
According to the question,
From the given Venn diagram,
Total number of attendees = 750
Number of attendees choose neither sandwich = 85
Number of attendees choose both turkey and Ham sandwich= 200
Total number of attendees choose ham sandwich = 400
'x' represents the number of attendees choose only turkey sandwich
As per condition of the sets in the Venn diagram we get,
[tex]400 + 85 + x = 750\\\\\implies 485 + x=750\\\\\implies x = 750-485\\\\\implies x = 265[/tex]
Hence, number of people had only turkey on their sandwich from the given Venn diagram is equals to 265.

C.cubed root of 2 (cos(60°) + isin(60°)).
D. Cubed root of 2 (cos(260°) + isin(260°))
Answers
If you raise a cube root of -2 to the third power, the resulting number will have a congruent argument. We have
-2 = 2(cos 180º + i sin 180º)
Pick a number from the 4 given options, and raise it to the third power using DeMoivre's theorem. For example,
[tex]\left(\sqrt[3]{2}\left(\cos90^\circ+i\sin90^\circ\right)\right)^3=2\left(\cos(3\cdot90^\circ)+i\sin(3\cdot90^\circ)\right)=2(\cos270^\circ+i\sin270^\circ)=-2i[/tex]
so the first option is not a cube root of -2 because the argument 270º is not congruent to 180º. Similarly, the second and fourth options are also not cube roots of -2.
On the other hand,
[tex]\left(\sqrt[3]{2}(\cos60^\circ+i\sin60^\circ)\right)^3=2(\cos180^\circ+i\sin180^\circ)[/tex]
so the third option is a cube root of -2.

Which statement best describes the function represented by the graph?
Answers
Answer:
Step-by-step explanation:
You read a graph from left to right, just like you would read words on a page in a book. At the left-most "side" of this graph, we are way up at positive infinity. As we move from left to right, the graph begins to drop in y values. A drop in y values indicates a decreasing graph. So it's decreasing, we have that part. As the graph grows up into y values that increase forever, it will also grow in the x direction to negative infinity. As the graph decreases in y values from left to right, the x values increase into positive infinity. So your choice is the second one: The function is decreasing on the interval (-∞, ∞).

V = 2,560 m^3
Step-by-step explanation:
The formula for the volume of a pyramid is...
[tex]V=\frac{1}{3}Bh[/tex]
B is the area of the base, which in this case is a rectangle. We need to find the area of the rectangle to plug in for B.
The formula for the area of a rectangle is...
[tex]l*w[/tex]
We can plug in the numbers.
[tex]16*24[/tex]
= 384
Now that we have B, we can plug that into the volume formula along with the height.
[tex]V=\frac{1}{3}(384*20)[/tex]
[tex]V=\frac{1}{3}*7,680[/tex]
V = 2,560 m^3
