Answer:
Kindly check explanation
Step-by-step explanation:
Organizations like NASA who explore space and planets often have to deal with measurement of very long distances such as the one stated above. The Major challenge with the distance written in the format expressed above is the difficulty to read, state or use in mathematical calculations as it is too explicit. A more effective method is to express this distance in standard format and more suitable long distant units such as miles.
For instance;
880,000,000,000,000,000,000,000 kilometers could be expressed as in standard form as ;
8.8 * 10^23 km

Answer:
x = 70
Step-by-step explanation:
180* (n-2)
180*(6-2)
180*(4) = 720
102 + 146 + 120 + 124 + 158 = 650
720 - 650 = 70
A polygon is a planar figure characterized by a limited number of straight-line segments. The value of the x is 70°.
What is a polygon?A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of the interior angles of a n-sided polygon is calculated using the formula,
Sum of the interior angles = (n-2) × 180°
For the given polygon, the number of sides is equal to 6. Therefore, the sum of the interior angles of the polygon is,
Sum of the interior angles = (6-2) × 180°
= 4 × 180°
= 720°
Further, the sum of the interior angles for the given polygon can be written as,
Sum of the interior angles = 102° + 146° + 120° + 124° + 158° + x°
720° = 102° + 146° + 120° + 124° + 158° + x°
x = 720° - (102° + 146° + 120° + 124° + 158°)
x = 720° - 650°
x = 70°
Hence, the value of the x is 70°.

Write the following using algebraic notation, using the letter x for any unknown numbers:
i think of a number, halve it, then subtract four.
Answer:
1/2x-4
Step-by-step explanation:
Since we don't know the number (unknown) we simplify it as a variable, x.
Then since you're taking half of x, place 1/2 next to x. Finally subtract 4, and it concludes to 1/2x-4.
How much do you need to sustract from 83/10 to 8
Answer:
[tex]\frac{3}{8}[/tex]
Step-by-step explanation:
Subtraction refers to an arithmetic operation that represents the operation of eliminating objects from a collection. Subtraction is meant by the minus sign.
Let [tex]x[/tex] be subtracted from [tex]\frac{83}{10}[/tex] to get [tex]8[/tex].
[tex]\frac{83}{10}-x=8\\\\x=\frac{83}{10}-8\\\\x=\frac{83-80}{8}\\\\x=\frac{3}{8}[/tex]
Therefore, [tex]\frac{3}{8}[/tex] should be subtracted from [tex]\frac{83}{10}[/tex] to get [tex]8[/tex].
Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
Step(i):-
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
Step(ii):-
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒ [tex]\frac{576}{9} = b^{3}[/tex]
⇒ 64 = b³
⇒ 4³ = b³
[tex](4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }[/tex]
b = 4
Final answer:-
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)

Maria and Veronica were asked to add two whole numbers. Instead, Maria subtracted the two numbers and got 10 while Veronica multiplied them and got 651. What was the correct sum
Answer:
31 + 21 = 52
Step-by-step explanation:
Calculation for the correct sum
First step is to factor 651 which means that 1 * 3 * 7 * 31 will give us 651
Second step is to find 3 possibilities numbers that will give us 10 as the difference
3 possibilities numbers =(31, 21), (93, 7), (217, 3)
Third step is to make use of equation 1 to find the numbers that has 10 as the difference among the 3 possibilities numbers
The number that has 10 as the difference is (31, 21) because 31-21 will gives us 10
Now Equation 1 = X – Y = 10
Where,
X=31
Y=21
Hence,
31 – 21 = 10
Since 31 – 21 gave us 10 as the difference which means that the correct sum will be:
Correct sum =31 + 21 = 52
Therefore the Correct sum is 31 + 21 = 52

Jeffrey went to the Outlets to buy some clothes. He bought a pair of pants for $59.99 and a nice shirt for $32.00. He read a sign saying that he would receive 30% off for all purchases. How much did Jeffrey spend?
Answer: 64.39 dollars
==========================================================
Explanation:
Before the discount, he would spend 59.99+32 = 91.99 dollars. This is before sales tax is added.
However, he gets 30% off, so he saves 0.30*91.99 = 27.597 = 27.60 dollars.
Meaning that he actually spends 91.99 - 27.60 = 64.39 dollars
--------------
As a shortcut, we can multiply 91.99 by 0.70 to get 64.393 which rounds to 64.39
The 0.70 is due to the fact that if he saves 30%, then he still has to pay the remaining 70%
Keep in mind that sales tax would need to be added on; however, your teacher doesn't mention the sales tax rate.

determine the slope between the two points
(-2,9) and (1,6) PLS I WILL GIVE BRAINIEST!!
Answer:
The slope between the two given point is -1
Step-by-step explanation:
The rule of the slope between two points (x1, y1) and (x2, y2) is
m = [tex]\frac{y2-y1}{x2-x1}[/tex]
Let us use this rule to solve the question
∵ The given points are (-2, 9) and (1, 6)
∴ x1 = -2 and y1 = 9
∴ x2 = 1 and y2 = 6
→ Substitute them in the rule of the slope above
∵ m = [tex]\frac{6-9}{1--2}[/tex]
→ Remember (-)(-) = (+)
∴ m = [tex]\frac{-3}{1+2}[/tex]
∴ m = [tex]\frac{-3}{3}[/tex]
→ Divide up by down
∴ m = -1
∴ The slope between the two given point is -1

options=2/3, 4/13, 11/13 and 8/13
Answer: 4/13
Step-by-step explanation: There are a total of 13 chocolates, and 4 of those are dark chocolate with peanuts.
Probability that the chocolate you eat is a dark chocolate with peanuts is 4/13.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Total number of milk chocolates = 7
Total number of dark chocolates = 6
Number of milk chocolates that have peanuts inside = 5
Number of dark chocolates that have peanuts inside = 4
Total number of chocolates = 7 + 6 = 13
Probability that the randomly selected chocolate is a dark chocolate with peanuts = 4/13
Hence the required probability is 4/13.
