Answer:
1. 9/10
2. 14/15
3. 1 1 /6 or 7/6
Step-by-step explanation:
1. Change the 5, the denominator to 10. 8/10
then add to 1/10 8/10 + 1/10= 9/10
2. Change both denimnators to 15. You will then get 9/15 and 5/15.
Add them together and get 14/15
3. Change both denominators to 6 and you will get 3/6 and 4/6.
Add them together to get 7/6.
If you want to make it into a mixed fraction it would be 1 1/6 (as in one and one-sixth)
Answer:
EF = 6.6
Step-by-step explanation:
Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.

X represents the number that would be added to the silver cars.
x/40= 4
X=40x4
x=160
Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4
Answer:
The model for the temperature of the drink can be written as
Step-by-step explanation:
For a cold drink in a hotter room, we can say that the rate of change of temperature of the drink is proportional to the difference of temperature between the drink and the room.
We can model that in this way
If we rearrange and integrate
We know that at time 0, the temperature of the drink was 52°F. Then we have:
We also know that at t=2, T=55°F
The model for the temperature of the drink can be written as
