Which of the following is the appropriate unit of a measure to express the weight of a mobile phone?

A. Liter

B. Milliliter

C. Gram

D. Milligram

Answer Explanation:

Here, we are required to find the unit of measuring mass. The SI unit of mass is kilogram but other derived units are grams, milligrams, microgram and more.

Q #1: An energy company’s stock price was $65.50 on Monday. On Tuesday, the price went up $1.50. On Wednesday, the price decreased from Tuesday’s price by $2.57. On Thursday, the price went up $2.25 from Wednesday’s price. Which of the following was the final price on Thursday?

A. $66.68

B. $65.79

C. $67.00

D. $64.43

Answer Explanation

We are tasked to find the stock price on Thursday from the given information. Here, we need to find the stock of each day from the price increase or decrease. If the price increases, we add to the previous day’s price and subtract if the price decreases.

Monday’s stock price=$65.50

Tuesday’s stock price is Monday’s plus $1.50=65.50+1.50=$67.00

Wednesday’s stock price went down by $2.57 from Tuesday’s=67.00-2.57=$64.43

Thursday’s stock price went up by $2.25 from Wednesday’s =64.43+2.25=$66.68

From the above evaluation, the stock price on Thursday was $66.68
Q #2: A person weighed themselves at 153 lb. Five months later they weighed themselves at 120 lb. Which of the following is the percent of weight the person lost over 5 months? (Round to the nearest percent.)

A. 38%

B. 22%

C. 19%

D. 29%

Answer Explanation

The percentage change in weight is found in three steps below:

Absolute change in weight=final weight-initial weight

Absolute change in weight= (left|120-153 ight|=left|-33 ight|=33)

Relative change in weight= (frac{absolute change}{initial weight}=frac{33}{153}=0.216)

Percent change=relative change * 100%

Percent change=0.216*100%=21.6%

The percent change in weight lost is 21.6 %, which is about 22%.
