Question

drag and drop the solution to each problem into the white rectangle not all choices will be used. a claudio bought tickets to a music festival that 225,000 people are expected to attend represent this value in scientific notation. b during a science lab, alyssa learned that the approximate radius of a grain of sand is 1.2 x 10^(-7) inches represent this value in standard notation. c marvin went fishing, and the difference in weight between the first two fish he caught was 0.00074 grams. represent this value in scientific notation. d scientists have discovered that the distance between earth and mars can be as close as 5.46 x 10^7 kilometers. represent this value in standard notation. 0.00012 5,460,000,000 22.5 x 10^4 7.4 x 10^(-9) 54,600,000 2.25 x 10^5 7.4 x 10^9 0.0012 drag these

Explanation:

Step1: Convert 225,000 to scientific - notation

Move the decimal point 5 places to the left. So, $225000 = 2.25\times10^{5}$.

Step2: Convert $1.2\times10^{- 7}$ to standard - notation

Move the decimal point 7 places to the left. So, $1.2\times10^{-7}=0.00000012$.

Step3: Convert 0.00074 to scientific - notation

Move the decimal point 4 places to the right. So, $0.00074 = 7.4\times10^{-4}$.

Step4: Convert $5.46\times10^{7}$ to standard - notation

Move the decimal point 7 places to the right. So, $5.46\times10^{7}=54600000$.

Answer:

a. $2.25\times10^{5}$
b. 0.00000012
c. $7.4\times10^{-4}$
d. 54600000
