Answer:

The second stove had a higher temperature when the stoves were turned off.

The first stove cooled down at a faster rate.

Step-by-step explanation:

first stove: T(t) = 180 - 2.55t can also be written as T(t) = -2.55t + 180

(180 is the y-intercept; -2.55 is the slope)

second stove = T(t) = mt + 200

(0,200) (40,130)

\frac{200 - 130}{0 - 40} = \frac{60}{-40} = \frac{3}{-2} = -1.5

T(t) = -1.5t + 200

A baseball team has won 8 out of the first 20 games and has 40 games remaining. The team needs a winning percentage of 62.5% mak
dimaraw [331]

Answer:

30 More Games for Playoffs | Win Percentage of 40% in Playoffs

Step-by-step explanation:

We find the total amount of games by adding first 20 and 40 remaining

This will leave us with 60 games

In order to calculate the playoff, we would have to calculate 62.50% in those 60 games.

62.50% is 5/8, we divide 60 by 8 and get 7.50

We multiply both sides by 7.50 and get 37.50/60

We subtract 8 from 37.50 and get 29.50

We round it to the nearest ones and get 30

In order to win the game they would need to win 30 more games

To calculate the final win percentage, we would add 2 and 3, which would give us 5.

After winning 2 and losing 3,

it would give us 2/5,

which in percentage is 40%

One fifth of a number plus five times that number is equal to seven times the number less 18. find the number.
Schach [20]
OK.  First we have to figure out names for all the numbers you mentioned.

The mysterious number . . . . . call it Q
One fifth of the number . . . . . 0.2 Q
Five times the number . . . . . . 5 Q
Seven times the number . . . . 7 Q

(One fifth plus five times the number) . . . 5.2 Q
(Seven times the number less 18) . . . . . . 7 Q - 18

You said that these last two things are equal, 

so I can write . . . . . . . . . . . . . . . . . .  7 Q - 18  =  5.2 Q

Now, subtract  7Q  from each side . . .  -18 = -1.8 Q

Divide each side by  -1.8 . . . . . . . . . .  10 = Q
