Answer:
After 15 minutes, the temperature of both the furnaces will be same.
Step-by-step explanation:
Let be the minutes when the temperature of both becomes same.
Now, as per question:
Temperature of the furnace after minutes that is cooling at the rate of 15 degree per minute is given as:
Temperature of the furnace after minutes that is heating at the rate of 5 degree per minute is given as:
Now, equating both the temperatures, we get
Therefore, after 15 minutes, the temperature of both the furnaces will be same.
Answer:
Basketball = 0.743
Step-by-step explanation:
Given
Tennis:
Starting Height = 200 cm
Rebound Height = 111 cm
Soccer Balls;
Starting Height = 200 cm
Rebound Height = 120 cm
Basketball:
Starting Height = 72 inches
Rebound Height = 53.5 inches
Squash:
Starting Height = 100 inches
Rebound Height = 29.5 inches
For measuring the bounciness of a ball, one needs that starting Height of and the rebound Height of that ball which have been listed out above.
Calculating the rebound ratio of each balls.
Rebound Ratio = Rebound Height/Starting Height
Tennis: 111/200= 0.556
Soccer Balls: 120/200 = 1.667
Basketball: 53.5/72 = 0.743
Squash: 29.5/100 = 0.295
From the rebounding ratio calculated above, it can be seen that basketball has the highest rebound ratio of 0.743 and is the bounciest of all whole Squash has the least rebound of 0.295 ratio, hence it is the least bounce of all.
Answer:
1. Infinitely Many Solutions
2. Zero Solutions
3. One Solution ( x = 6 )
Step-by-step explanation:
1.
12x + 8 = 2( 6x + 4 )
12x + 8 = 12x + 8
2.
2( 2x + 1 ) = 4x + 3
4x + 2 = 4x + 3
2 = 3
3.
4( x + 1 ) = 3x + 10
4x + 4 = 3x + 10
x + 4 = 10
x = 6
Hopefully this helps!
Brainliest please?
Y=3x+10
10 represents the fee
X= amount of hours
3 is the cost per hour.
Thats what you would use, so now 2/10 is .2 When you divide so you move the decimal so 20%
The percent increase is 20%
