How much
liquid does Sylvia have in all?
Round to the nearest 100 milliliters to estimate. Then, find the actual answer.

should be 900ml if rounded to the nearest 100ml

Step-by-step explanation:

238 + 502 + 178 =  918

918 milliliters, 900 as an estimate.

Step-by-step explanation:

Simple addition?

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
