Answer:
- 40 ml of water must be added.
Step-by-step explanation:
Initial volume of mixture is 100 ml with oil to water ratio of 1 : 4.
First, let's find the volume of each component.
If the oil is x then water is 4x according to ratio and their sum is 100 ml:
- x + 4x = 100
- 5x = 100
- x = 20
So, we have 20 ml of oil and 80 ml of water.
Now, let's added volume of oil be y. Then we have the ratio:
- (20 + y)/80 = 1/2
- 20 + y = 40
- y = 20
So, we have 40 ml of oil and 80 ml of water.
Lastly, let's added water be z. Then we have the ratio:
- 40/(80 + z) = 1/3
- 80 + z = 120
- z = 40
We must add 40 ml of water.
Answer:
10^-99, 10^-17, 10^-5, 10^5, 10^14, 10^30
Step-by-step explanation:
Each root adds a exponent behind the initial one. The negatives add a decimal point and zeros in front
If y/x does not always equal the same
we have given that 
.
we need to find 
.
we know that we need to plug t in place of x in the equation f(x)=2^x.
.for example for 
they have plugged 4 in place of x. so we plug in plug t in place of x .
