A piece of hot metal is cooling at a linear rate. Its Temp. After 4 minutes is 310 deg. Its Temp. After 7 minutes is 205 deg. Wh
rodikova [14]

Answer:

It'll take 12 minutes to be at 30 degrees.

Step-by-step explanation:

Since the metal is cooling at a linear rate then the rate of degrees per minute should be the through the cooling process. From 4 minutes to 7 minutes there was a span of 3 minutes and in that time the metal cooled 105 degrees. So the metal is cooling at a rate of

rate = 105/3 degrees/minute = 35 degrees/min

To reach 30 degrees from 205 it should cool down an additional 175 degrees so it'll take:

minutes = deegrees/rate = 175/(35) = 5 minutes

Since the metal had a temperature of 205 degrees in 7 minutes, then it'll take 12 minutes to be at 30 degrees.

A baseball team consists of 2 stars, 13 starters, and 10 substitutes. For tax purposes, the team owner must value the players. T
inessss [21]

Answer:

The total value of the team=$8.2 million

Step-by-step explanation:

Step 1

Determine the total value of the team as follows;

V=(S×s)+(T×t)+(B×b)

where;

V=total value of the team

S=total value per star player

s=number of stars in the team

T=total value per starter

t=number of starters in the team

B=total value per substitute

b=number of substitutes in the team

In our case;

S=1 million per year

s=2 stars

T=400,000

t=13

B=100,000

b=10

replacing;

V=(1,000,000×2)+(400,000×13)+(100,000×10)

V=(2,000,000+5,200,000+1,000,000)

V=8,200,000=8.2 million

The total value of the team=$8.2 million
