The speed of sounds in water is 1.46 x 10^3 meters per second. The speed of sound in air is 3.31 x 10^2 meters per second. How much faster does sound travel in water than it air?
Answer:
Hey there!
1.46x10^3-3.31x10^2
14.6x10^2-3.31x10^2
11.29x10^2

The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.
Speed :The speed is the distance travelled per unit of time by a sound wave
Given informationSpeed of sound in water is [tex]1.46 \cdot 10^3[/tex]
Speed of sound in air is [tex]3.31 \cdot 10^2[/tex]
To find how much faster does travel , we need to subtract the speed
To subtract we need to make the exponents same
[tex]1.46 \cdot 10^3\\14.6 \cdot 10^2[/tex]
Now we subtract ,
[tex]14.6- 3.31= 11.29\\\\11.29 \cdot 10^2\\1.129 \cdot 10^3[/tex]
The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

what's the probability of pulling two red cards in a row from a deck of cards?
Hey there! I'm happy to help!
Let's say that we don't have jokers. In that case, there are 52 cards, and half of them are red (so 26 are red). The probability of pulling a red card once is 1/2 since half the cards are red.
If we pick one out, there are only 51 total cards left and 25 red cards. So, the probability of picking one again would be 25/51.
We multiply the probabilities of these two events to find the probability of them both happening.
1/2×25/51=25/102
The probability of picking two red cards in a row is 25/102 or around 24.5%.

Alex and leanardo went to the movies a drink cost $4.00 each and a bag of popcorn cost $ 5.00 each how many would they spend of they bouth 2 drinks and 2 Bags of popcorn
If Alex and Leonardo are both buying two bags of popcorn and drinks then the overall price would be $18.00.
$4.00 + $4.00 = $8.00 + $5.00 + $5.00 = $18.00
Therefore, they would spend 18 dollars.

The layout for European license plates is XXX – XXXX. The first three digits are letters and the last four are numbers. The exclusions on the plates are that the first three letters cannot be the same (i.e. AAA) and the last four cannot be the same (i.e. 1111). How many different possible plates can be made? Show all work and explanations necessary.
Answer:
No. of Plates Possible = 78624000 = 7.86 x 10⁷
Step-by-step explanation:
We have total 7 places to fill in order to form a plate. So, we see all the number of options available for each of the position:
No. of Options for First Place = 26 (All alphabets of English)
No. of Options for Second Place = 25 (Due to no repetition)
No. of Options for Third Place = 24 (Due to no repetition)
No. of Options for Fourth Place = 10 (Digits from 0 to 9)
No. of Options for Fifth Place = 9 (Due to no repetition)
No. of Options for Sixth Place = 8 (Due to no repetition)
No. of Options for Seventh Place = 7 (Due to no repetition)
Hence, the total possible plates that can be made are given by multiplying
the options to select in each place:
No. of Plates Possible = 26*25*24*10*9*8*7
No. of Plates Possible = 78624000 = 7.86 x 10⁷
After 8 hours of snow, the temperature had changed by a total of -16 degrees. What was the average change in temperature each hour while it was snowing?
Answer:
-2 degrees
Step-by-step explanation:
Divide -16 by 8:
-16/8
= -2
So, the average change in temperature each hour was -2 degrees.
The average change of weather dropped 2 degrees for every hour is snowed.
Here,
After 8 hours of snow, the temperature had changed by a total of -16 degrees.
We have to find the average change in temperature in each hour.
What is Average?
Average is the middle value of the given sets of values.
Now,
After 8 hours of snow, the temperature had changed by a total of -16 degrees.
Hence, The average change in temperature in each hour = -16 ÷ 8 = -2
Therefore, The weather dropped 2 degrees for every hour is snowed.

Answer:
C: x+y=27 and y=6+2x
Step-by-step explanation:
First part: If the sum of the two is 27, then it means that it is x + y = 27, because sum means addition.
Second part: The larger number (y) is 6 more than twice the smaller number (x). Twice a number means that it is that number multiplied by x, so it is 2x. 6 more means we add 6 to it so the second equation is y=6+2x.

Answer:
The answer is "Option C"
Step-by-step explanation:
The choices were missing in the question, which is defined in the attached file please find it.
To attend university, Chole should pay the cost of a room and board each semester. Even though the Chole will not be in college, she will still have a room as well as a board and continue living.
If she will not attend college, it also has to equate rooms and board costs per six months since increase towards the room or board charges. If there's an increase in rooms and boarding costs because she did not understand below the rise in their school fees, therefore the financial cost reduces that desire of she attend.the powers of the variable in the algebraic expression should be

You are setting up a part-time business with an initial investment of $12,000. The unit cost of the product is $11.50, and the selling price is $19.00.Required:a. Find equations for the total cost C (in dollars) and total revenue R (in dollars) for x units.b. Find the break-even point by finding the point of intersection of the cost and revenue equations units.c. How many units would yield a profit of $1000?
Answer:
Given Initial investment = $12,000
Cost per unit = $11.50
Selling price per unit = $19
a. For x unit
Total cost = Initial investment + Cost per unit * no of unit
= 12,000 + 11.50(x)
c(x) = 12,000 + 11.50(x)
R(x) = Selling price per unit * no of items
R(x) = 19 * x
R(x) = 19x
b. Break even point = R(x) = C(x)
19x = 12,000 + 11.50x
19x - 11.5x = 12,000
7.5x = 12,000
x = 12,000 / 7.5
x = 1600
So, break even point x = 1,600
c. For Profit = $1,000
P(x) = 1,000
P(x) = R(x) - C(x)
1000 = 19x - (12,000 + 11.5x)
1000 =19x - 11.5x - 12000
7.5x = 12000 + 1000
7.5x = 13000
x = 13000/7.5
x = 1733.33
So x = 1733 units
Hence, 1733 units will yield for $1,000 profit
