- A unit of area often used in measuring land areas is the hectare, defined as 104 m2. An open-pit coal mine consumes 75 hectares of land, down to a depth of 26 m, each year.What volume of earth, in cubic kilometers, is removed in this time?Thanks for your help. A hot air balloon rose from a height of 10 m to 40 m in 3 minutes. Answer this question: What was the balloon’s rate of change in 1 minute and 1 second? m: y2-y1/x2-x1 m: 40 - 10 / 3 m: 10 m/minOne mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters. c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube? d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?
- Jamie used a microscope to measure the diameter of a hair. She found that the diameter of the hair was 0.000072 meter. How is this number written in scientific notation.Answer to question 10How do you calculate the miles you are getting per gallon of gasoline if you record the mileage readings from your car’s odometer each time you fill up the gas tank? Two odometer readings should be inputted, one reading is before you fill up the gas tank, and the second reading is when you refill the gas tank. The third input is the quantity of gallons of gasoline purchased when the gas tank is refilled. After inputting these 3 values, calculate and output: The miles traveled between gas refills The average miles per gallon based on the miles traveled and the amount of gasoline purchased after the time the gas tank is refilled (Use sequential structure)

Do not include units.According to a survey, 85% of American adults eat salad at least once a week. A nutritionist suspects that the percentage is higher than this. She conducts a survey of 200 American adults and finds that 171 of them eat salad at least once a week. Conduct the appropriate test that addresses the nutritionist's suspicion. Use an a = 0.05 level of significance. State the null and alternative hypothesis: What parameter are we testing? Ho: H₁: Assumptions: SRS, n < 0.05N, npo (1 - po) By hand, test statistic is (Round to 5 decimals): P-value. Round to 4 decimals: Conclusion: There is (enter sufficient or insufficient) evidence at the a = 0.05 level of significance to conclude that the percentage of adult Americans that eat salad at least once a week is ("equal to" or "higher than" or "less than" or "not equal to") 85%.The world population in billions is approximately P = 7.4e0.010" where t is in years since 2016.
