Answer:

The equation form is, a(t)=-1000t+32800    

Step-by-step explanation:

Given : After descending for 8 minutes, an airplane is at an altitude of 24800 feet. After 20 minutes, the plane's altitude is 12800 feet.

To find : Write an equation in the form a(t)=mt+b that shows the altitude, a, after t minutes of descent ?

Solution :

The equation is in form, a(t)=mt+b

Where, 't' is the time in minutes and 'a' is the altitude,

After descending for 8 minutes, an airplane is at an altitude of 24800 feet.

i.e. a=24800 and t=8

Substitute in the equation,

24800=m(8)+b

24800=8m+b ......(1)

After 20 minutes, the plane's altitude is 12800 feet.

i.e. a=12800 and t=20

Substitute in the equation,

12800=m(20)+b

12800=20m+b ......(2)

Solving (1) and (2) by subtracting them,

24800-12800=8m+b-(20m+b)

12000=8m+b-20m-b

12000=-12m

m=\frac{12000}{-12}

m=-1000

Substitute in equation (1),

24800=8(-1000)+b

24800=-8000+b

24800+8000=b

b=32800

So, The equation form is, a(t)=-1000t+32800

Janie and Jasmine are playing three games at an arcade. Each of the games requires either 2, 3, or 4 tokens. The girls plan to p
Brrunno [24]

Answer:

m+2n+2p=16 tokens or m+2(n+p)= 16 tokens

Step-by-step explanation:

First, we must understand how many tokens they have.

Janie played the 3-token game four times, so she used 12 tokens  (3n x 4 = 12). Jasmine played the 4-token game five times, so she used 20 tokens (4p x 5 = 20).

Added up, the girls have 32 tokens (12+20 = 32 tokens (t)).

In order to play a round of the three games, 9 tokens are required (m+n+p = 9 / 2+3+4 = 9) by each girl. (32t-18t=14) 14 tokens are left after taking a ride in every game each. 14 left divided by 2 will leave 7 more tokens for each girl. You can split these 7 tokens into an n+p = 7 tokens

Thus,

Each girl can ride as follows:

m+2n+2p=16 tokens or m+2(n+p)= 16 tokens

Katie buys a large pizza for $14.99 and bottles of soda for $1.50 each. If the total cost was $23.99, how many bottles of soda (
Nady [450]

The number of soda bottles Katie bought is 6

The given parameters are:

  • Large Pizza = $14.99
  • Soda = $1.50 per bottle
  • Total cost = $23.99

Assume the number of soda bottle is x.

So, we have:

Total = Pizza + Soda \times x

This gives

23.99 = 14.99 + 1.50\times x

Subtract 14.99 from both sides of the equations

9 = 1.50\times x

Divide both sides of the equations by 1.5

6=x

Rewrite the equation as

x = 6

Hence, the number of bottles is 6
