Answer:
Step-by-step explanation:
The question is incomoplete. Here is the complete question.
The function T(d)=10d + 20 gives the temperature in deegrees celcius inside the earth as a function if d, the depth in kilometers ,Find the temperature at 5km, 20km and 100km
T(d)=10d + 20
T(5)=10(5) + 20
T(5)= 50+ 20
T(5) = 70
Hence the temperature is 70 when d = 5km
when d = 20km
T(20)=10(20) + 20
T(20)= 200+ 20
T(20) = 220
Hence the temperature is 220 when d = 20km
when T = 100km
T(100)=10(100) + 20
T(100)= 1000+ 20
T(100) = 1020
Hence the temperature is 1020 when d = 100km
Answer:
The Greatest Common Factor (GCF) for 56 and 84, notation CGF(56,84), is 28.
Step-by-step explanation:
The factors of 56 are 1,2,4,7,8,14,28,56;
The factors of 84 are 1,2,3,4,6,7,12,14,21,28,42,84.
So, as we can see, the Greatest Common Factor or Divisor is 28, because it is the greatest number that divides evenly into all of them.
plz mark me as brainliest :)
Answer:
250 days.
Step-by-step explanation:
Let x represent number of days.
We have been given that of the 2,500 tons of ore mined daily at a quarry, 0.4 percent results in a certain pure metal.
Let us find the amount of pure metal by calculating 0.4% of 2500.
Amount of pure metal mined in x days will be 
.
Since we need total pure metal production equal to 2500 ton, so we can set an equation as:
Therefore, it will take 250 days of mining for the total amount of pure metal produced at the quarry to be equal to the daily amount of ore mined.
