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:

-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:

To get from step 1 to step 2, apply the distributive property to eliminate the parentheses.

To get from step 2 to step 3, combine like terms on the right side of the equation.

To get from step 3 to step 4, apply the addition property of equality to isolate the variable term.

To get from step 4 to step 5, apply the multiplication property of equality to isolate the variable, x.

To get from step 5 to step 6, apply the symmetric property to rewrite the equation with the variable on the left side.

The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

The speed   is the distance travelled per unit of time by a sound wave  

Speed 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]

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

Step-by-step explanation:

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%.

Have a wonderful day! :D

Step-by-step explanation:

Hope this helps! :)

Answer:

13000

Step-by-step explanation:

2 x 65 =130

Add 2 more 0s

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
