Scientific notation is a tool that is used frequently in science, including astronomy, chemistry, biology, and more. In this activity, imagine that you are a student intern at NASA and are researching information about travel within our solar system. You will complete a series of tasks using what you know about scientific notation and what you discover about our solar system to calculate distances that astronauts may use for their next trip to space.
Part 1
Using technology or other resources, research the average distance that each planet is from the sun (in kilometers). Once you have found the distance, create a chart showing each planet's distance from the sun. The sun itself will not receive a label since it is your starting point. For example, Mercury is located an average of 57,909,000 km from the sun, so on the chart, Mercury would be labeled with a distance of 57,909,000. Use the example of the chart below to help you get started:
Planet Distance from sun (in km) Distance in scientific notation
Mercury 57,909,000

Answer:
We use scientific notation to lessen the load in terms of calculation that must be done. Its often good practice to go to the tenth place.In terms of your question please look at the provided image!
Answer:
5.7909 * 10^7
Step-by-step explanation:
Scientific notation uses a number from 1 to under 10 and an integer power of 10.
57,909,000 = 5.7909 * 10,000,000 = 5.7909 * 10^7

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
x + 5y = 0
3y + 2x = -21
Step 2: Rewrite Systems
x + 5y = 0
Subtract 5y on both sides: x = -5yStep 3: Redefine Systems
x = -5y
3y + 2x = -21
Step 4: Solve for y
Substitution
Substitute in x: 3y + 2(-5y) = -21Multiply: 3y - 10y = -21Combine like terms: -7y = -21Isolate y: y = 3Step 5: Solve for x
Define equation: x + 5y = 0Substitute in y: x + 5(3) = 0Multiply: x + 15 = 0Isolate x: x = -15Which situation can be represented by the expression -2+(-1)

To go on a summer trip, Ravi borrows $800. He makes no payments until the end of 3 years, when he pays off the entire loan. The lender charges simple interest at an annual rate of 5%. Answer the following questions. If necessary, refer to the list of financial formulas. (a) How much total interest will Ravi have to pay? Х 5 ? s) (b) What will the total repayment amount be (including interest)?
Answers
Answer:
srry but search 12 z6xs
Step-by-step explanation:
(a) The total interest that Ravi will have to pay is $120. (b) The total repayment amount will be $920.
a) The interest rate is 5% per year, so Ravi will pay 5% * 800 = $40 per year in interest.
Since he borrowed the money for 3 years, he will pay a total of 3 * 40 = $120 in interest.
b) The total repayment amount will be the principal amount of $800 plus the interest of $120, for a total of 800 + 120 = $920.
Simple interest formula: I = P * r * t
Where:
I is the interest
P is the principal amount
r is the interest rate
t is the time in years
Interest per year: 5% * 800 = $40
Total interest: 3 * 40 = $120
Total repayment amount: 800 + 120 = $920

Find the values of a and b so that the linear system has the given solution.
Given Solution: (2, 1)
Equation 1: ax - by'= 4
Equation 2: bx - ay = 10
Answers
Answer:
The values are a=6, b=8
Step-by-step explanation:
The following system of equations
ax - by = 4
bx - ay = 10
Has the solution x=2, y=1. Substituting:
2a - b = 4 [1]
2b - a = 10 [2]
Multiply [1] by 2:
4a - 2b = 8
Add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [1]:
2*6 - b = 4
b = 12 - 4
b = 8
The values are a=6, b=8

A certain bacteria can divide every hour. Which of the following equations represents the number of cells, N, that is present after t hours?
A
N(t)=2t
B
N(t)=2/t
C
N(t)=2t
D
N(t)=t2
Answers
Answer:
N(t) = N0/2^t
Step-by-step explanation:
Given that:
Number of cells present after t hours = N
Let initial number of cells = N0
Using the exponential decay relation:
N(t) = N0(1/2)^t
N(t) = N0/2^t
Hence, the number of cells N present after t hours is N(t) = N0/2^t.

Which ordered pair is a solution of this equation? -6x + y = 35 Click on the correct answer. (-1,-7 (-6,-1) (-1,-6) (-7,-1)
Answers
Answer:
The ordered pair (-6, -1) is the only solution.
Step-by-step explanation:
-6x + y = 35
Let's plug in the points.
(-1, -7) --> -6(-1) - 7 = 6 - 7 = -1 which does not equal 35
(-6, -1) --> -6(-6) -1 = 35
(-1, -6) --> -6(-1) - 6 = 0 which does not equal 35
(-7, -1) --> -6(-7) - 1 = 41 which does not equal 35
Missing length?? Please help me out
Answers
Answer:
The missing length is 12
Step-by-step explanation:
Required
Determine the missing length (LS)
If RS = 28 and KS = 14
Then
[tex]KR = RS - KS[/tex]
[tex]KR = 28 - 14[/tex]
[tex]KR = 14[/tex]
The sides of the given shape are directly proportional.
This implies that:
[tex]KS : LS = RS : QS[/tex]
[tex]KS = 14[/tex]
[tex]RS = 28[/tex]
[tex]QS = 12 + LS[/tex]
[tex]LS = ??[/tex]
So, the expression becomes:
[tex]14 : LS = 28 : 12 + LS[/tex]
Represent as a fraction
[tex]\frac{14}{LS} = \frac{28}{12 + LS}[/tex]
Cross Multiply:
[tex]14(12 + LS) = 28 * LS[/tex]
Divide through by 12
[tex]12 + LS = 2 * LS[/tex]
[tex]12 + LS = 2 LS[/tex]
Collect Like Terms
[tex]2LS - LS = 12[/tex]
[tex]LS = 12[/tex]
The length of the missing side is 12
What is the difference of 620 and 89.7?
Answers
Answer: 530.3
Step-by-step explanation:
Difference means to subtract
620-89.7=530.3
Answer:
530.3
Step-by-step explanation:
You want to subtract 620-89.7. If you want to use the standard algorithm you have 620.0-89.7. You "borrow" from the 2 in the tens place, then "borrow" from the ones place. To subtract 10-3 tenths. Then you subtract the ones place which is 9-9=0 ones. Now you subtract 62-8=53 tens. So you have 530.3 as the difference.

I'm not quite 'out there in the real world' but whenever I'm limited on money and whatnot, instead of trying to go ahead and add it all up by the exact price I'll round it up to the nearest dollar. Sometimes I'll even round it up two dollars. If it's something like '$25.98', I'll figure $27.00. That always helps me not spend as much.
Making a list and strictly following the list helps as well. I wouldn't try to spend money on things unessential, or things that you really don't have the money for.

Step-by-step explanation:
First, we have to solve 8 to the power of 3 according to PEMDAS, which will give us 512.
Since we have to follow PEMDAS or GEMDAS (whichever you know), we will have to multiply 9 by 2 next. That will give us the equation: 512 - 18 / 3
Then we have to divide 18 by 3 to give us 6 which will give us the equation: 512 - 6 which we can solve to get 506
