Planet Earth has an approximate diameter of 1.2742 · 10 10 millimeters. The sun has a diameter of 1.391 · 10 6 kilometers.
Part I: Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Earth's diameters?
Part II: Approximate how many times greater the sun's diameter is than planet Earth's.
Answers
Sun's diameter is 109.16653 times more than Earth's diameter.
Units of Length:Physical quantities such as length, current, mass, volume, temperature, area, intensity, and others are represented by units of measurement. To express the size of physical quantities, we employ a variety of measuring units, including traditional ones, the metric system, and US customary units.
Units of Length are
Kilometers, Nanometre, Millimeters, Centimeters, Meters, and Decimetres
Here we have
Planet Earth has an approximate diameter of 1.2742×10¹⁰ millimeters.
The sun has a diameter of 1.391×10⁶ kilometers.
Part I:
Given that, for every kilometer, there are 1,000,000 millimeters,
Here 1000000 = 10⁶
Then the diameter of the earth = 1.2742×10¹⁰/10⁶
= 1.2742×10⁴
Here using the unit kilometer is best to represent the lengths of the sun and earth's diameter because it allows using fewer digits compare to millimeters.
Part II
Let Earth's diameter is less 'x' times than Sun's diameter
=> [ 1.2742×10⁴ ] × x = 1.391×10⁶
=> x = 1.391×10⁶/1.2742×10⁴ = 1.0916653 × 10² = 109.16653
Therefore,
Sun's diameter is 109.16653 times more than Earth's diameter.

Answers
Answer:

According to the graph, the vertex is at (2, - 3).
The axis of symmetry passes through the vertex, so its x-coordinate determines the vertical line:
x = 2The matching answer choice is 1.
Answer:
1. (2, –3); x = 2
Step-by-step explanation:
The vertex of a parabola is its turning point. This is:
the minimum point of a parabola that opens upwards, or the maximum point of a parabola that opens downwards.From inspection of the given graph, the vertex of the parabola is (2, -3).
The axis of symmetry is the vertical line that passes through the vertex and divides the parabola into two equal (symmetrical) halves.
The axis of symmetry is the x-value of the vertex.
Therefore, the axis of symmetry of the graphed parabola is x = 2.

If segments DE and AB are parallel, which of the following expressions will help Eshaal determine the length of segment BC
Answers
The expression that will help Eshaal determine the length of segment BC is: BC = DE - AB
Since segments DE and AB are parallel, we can use the following expression to calculate the length of segment BC: BC = DE - AB. This expression states that the length of BC is equal to the length of DE minus the length of AB.
If segments DE and AB are parallel, we can use a simple expression to find the length of segment BC. This expression is: BC = DE - AB. This expression states that the length of BC is equal to the difference of the length of DE and the length of AB. In other words, if we know the lengths of segments DE and AB, we can calculate the length of segment BC by subtracting the length of segment AB from the length of segment DE. This expression is a useful tool for finding the length of segment BC when we know the lengths of segments DE and AB.

Answers
The restaurant owns the 225 forks if 4% of the fork owned by the restaurant.
Percentage are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
A dishwasher at a restaurant washes 9 fork.
These fork represent 4% of the fork owned by the restaurant.
Now, Solving the question:
We can get our answer by displaying as an equality
= 9 to 4/100
= x to 100/100
You can multiply 4 by 25 to get 100 so to get the amount of forks, multiply 9 by 25

A bag contains 6 red marbles, 3 blue marbles and 5 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be red?
Answers
Step-by-step explanation:
First, you want to find out how many total marbles there are. We know there are 6 red, 3 blue, and 5 green. So, 6+3+5=14 total marbles. Since there are 3 blue marbles, the probability of selecting a blue marble is 3/14. This is because you are selecting from a bag of 14 total marbles, 3 of which are the color you want.
To answer this, we can use the equation P (A) = n(A)/n(S). In this equation, P (A) is the probability of the event, n (A) is the number of successful outcomes, and n (S) is the total number of possible outcomes.
For this particular problem, n (A) is 6; since there are 6 red marbles. To calculate n (S), we need to know the total number of marbles, which is 6 + 3 + 5 = 14. So, n (S) = 14.
Plugging these values into our equation gives us P (A) = 6/14, which simplifies to 3/7. To express this as a percentage, we multiply 3/7 by 100 to get 42.9%. To express this to the nearest thousandth, we can round this value to 43%.
Therefore, the probability that all three marbles drawn will be red is 43%, to the nearest thousandth.
It's important to remember that probabilities always need to add up to 100%. In this example, if the probability of drawing three red marbles is 43%, then the probabilities of drawing three blue marbles and three green marbles combined must be 57%.

To find the unit price of bananas, we need to divide the total price by the number of bananas.
Unit price = Total price / Number of bananas
In this case, the total price is $3.20 and the number of bananas is 4.
Unit price = $3.20 / 4
Unit price = $0.80
So the unit price of bananas in this grocery store is $0.80 per banana.

Answers
He should use $5 off coupon to get the better deal. This will make the price of helium tank $33 which is less than $10% off i.e $34.2.
What is a coupon?"Coupon" is a term used when bonds were printed on paper. The bondholder would receive a certificate serving as a representation of the bond. On the side of the document would be tear-off coupons that the bondholder could present to the company that issued the bond to receive the coupon payment.
The coupon rates are set by the governments or corporations that issue the bonds, and they can differ significantly depending on the term of the bond and/or the stability of the issuing entity. In order to compensate for the holder's longer wait for the final payment, a 30-year-term bond, for example, might have a higher rate than a note with a 1-year term.
Price when $5 off = 38 - 5
= $33
Price when 10% off = 38 - (38 × 5/100)
