The double of 25 is (25+25), or (25x25). 7 less would be (25+25) -7. Figure out what 25 + 25 is, then subtract 7 from your answer.
Answer: 1/10
Step-by-step explanation:
From the question, we are informed that Karen spent 7/10 hour reading and 3/5 hours writing in her journal.
To calculate how much longer karen spent reading than writing in her journal, we have to subtract 3/5 from 7/10. This will be:
= 7/10 - 3/5
Note that the lowest common multiple of 5 and 10 is 10.
= 7/10 - 6/10
= 1/10
Therefore, the answer is 1/10
Answer:
1. An Experimental
2. Dependent
3. Independent
Step-by-step explanation:
Considering the description of how the research was carried out, it can be concluded that This study is an example of AN EXPERIMENTAL study. This because the researcher is trying to study the effectiveness of a new drug for lowering cholesterol
The difference in cholesterol level is the DEPENDENT variable. This is because the difference in cholesterol level is what the researcher wants to determine.
The treatment with a drug or placebo is the INDEPENDENT variable. This is because this is what the researcher manipulates to determine the difference in cholesterol level which is the dependent variable in this experimental study.
Answer: $3,581
Step-by-step explanation:
As she plans to save from her net income, we have to find the net income first:
= Net income - Federal taxes - Social and Medicare taxes
= 33,000 - (33,000 * 20%) - (33,000 * 7.65%)
= $23,875.50
The savings will be:
= Net income * Savings percentage
= 23,875.50 * 15%
= $3,581.325
= $3,581
