An airplane begins decreasing its altitude as it approaches the runway. At time t=1, the pilot notes that he has an altitude of 30,000 feet. One minute later, his altitude drops to 29,450 feet. One minute after that, his altitude drops to 28,900 feet. Assuming this pattern continues, write a recursive formula for the altitude of the plane A(t) after t minutes.(1 point)

A(t)=30000+550(t−1)

A(t)=A(t−1)−550 for t>1, where A(1)=30000

A(t)=A(t−1)+550 for t>1, where A(1)=30000

A(t)=30000−550(t−1)

Answer

x=20

Step-by-step explanation:

  (x-3) + (8x+3) = 180

         9x = 180

            x=20

Answer:

x = 8

y = 14

the short stanzas contain 8 lines

the long stanzas contain 14 lines

Step-by-step explanation:

lets call the short stanzas x

and the long stanzas y

using given information, you can make this equation

9x + 9y = 198

you can also make this equation

9x + 6y = 156

simplify the first equation

9x + 9y = 198

9x = 198 - 9y

x = 198/9 - y

x = 22 - y

substitute x for 22 - y in the second equation to find y

9(22 - y) + 6y = 156

198 - 9y + 6y = 156

-9y + 6y = -42

-3y = -42

y = 14

substitute y for 14 in the first equation to find x

9x + 9y = 198

9x + 9*14 = 198

9x + 126 = 198

9x = 198-126

9x = 72

x = 72/9

x = 8

Answer:

[tex]a_{64} = -313[/tex]

Step-by-step explanation:[tex]a_{64} = 2 -135[/tex]

This is the Arithmetic Sequence Formula->  [tex]a_{n} = a_{1} + (n+1) d[/tex]

1) The d represents your difference of the equation. You can find it by finding a pattern between the three numbers given, which is -5

2) Now that we've found our difference, we can plug it into this lovely sequence we have [tex]a_{64} = a_{1} + (64-1) -5[/tex] (by the way, your n represents your term that you plug into the equation)

3) [tex]a_{64} = 2 + (64-1) -5[/tex]  This also means that [tex]a_{1}[/tex] is our first term, which is 2

4) Simplify [tex]a_{64} = 2 + (63) -5[/tex] --> [tex]a_{64} = 2 +-315[/tex]

5) [tex]a_{64} = -313[/tex]

The formula is confusing at first, but it becomes easier once your learn the patterns!

Answer:

24

Step-by-step explanation:

Answer:

125 is 30% of the number 24, hope this helps

Step-by-step explanation:

We have, 125% × x = 30

or, 125/100 × x = 30

Multiplying both sides by 100 and dividing both sides by 125,

we have x = 30 × 100/125

So your answer is X=24

Answer:

O

Answer:

x = 26, y = 19

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{ST}{NP}[/tex] = [tex]\frac{RS}{MN}[/tex] , substitute values

[tex]\frac{x}{13}[/tex] = [tex]\frac{32}{16}[/tex] = 2 ( multiply both sides by 13 )

x = 26

and

[tex]\frac{MP}{RT}[/tex] = [tex]\frac{MN}{RS}[/tex] , substitute values

[tex]\frac{y}{38}[/tex] = [tex]\frac{16}{32}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 38 ( divide both sides by 2 )

y = 19

Answer:

10 days

Step-by-step explanation:

The Smith family is looking to rent a large truck for their upcoming move. With Rose's Moving, they would pay $40 for the first day plus $6 per additional day. With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day. Before deciding on which company to use, Mrs. Smith wants to find out what number of additional days would make the two choices equivalent with regards to cost. How many additional days would that be?

Let the number of additional days = x

With Rose's Moving, they would pay $40 for the first day plus $6 per additional day.

40 + 6x

With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day.

90 + x

Comparing both

40 + 6x = 90 + x

6x - x = 90 - 40

5x = 50

x = 50/5

x = 10

The number of additional days = 10 days

Answer:

12

Step-by-step explanation:

Answer: 10

Step-by-step explanation: Each side if the smaller shape is  multiplied by 1.5 to get the dimensions of the larger shape. To find the value of x, you divide 12 by 1.5. Then you add 2 to that answer to get the value of x.  [tex]12/1.5 = 8 + 2 = 10[/tex]

Answer: 17

Step-by-step explanation:

2 x2 is 4  4+13 is 17

Answer: 30 cm

Step-by-step explanation: Take note that ^2 means to the second power.

a^2 + b^2 = c^2 (hypotenuse)

18^2 + 24^2 = c^2

324 + 576 = c^2

900 = c^2

To find the length of c you have to find teh square root of 900.

√c^2 = √900

c = 30

The length of the hypotenuse is 30 cm!

Step-by-step explanation:

Have a lovely day :)

Answer:

Ok, this is pretty simple. So, if it rises 6 degrees every five days, then we have to figure out how many "five days" are in 30 days. It would be 6! So now all we have to do is multiply. 6 times 6 equals 36 degrees.

The answer is 36 degrees.

Step-by-step explanation:

Answer:

36

Step-by-step explanation:

If it rises 6 degrees every 5 days, we just need to figure out how many 5 days are in 30 days. When you solve, you'll get 6. Now we can just multiply 6 x 6 = 36. Hope this helped, please mark brainliest if it did

Answer:

7

Step-by-step explanation:

Answer:

Step-by-step explanation:

-5x + 7y = -34     ⇒  -5x = -34  - 7y

    -5x + 3y = -6

-34  - 7y + 3y = -6

-34 - 4y = -6          {add 34 to both sides}

  -4y = 28             {divide both sides by (-4)}

     y = - 7

-5x + 3y = -6

-5x + 3(-7) = -6

-5x - 21 = -6        {add 21 to both sides}

-5x = 15            {divide both sides by (-5)}

  x = -3
