e. What is the average of 40 and 70 ? What number is halfway between 40 and 70 ? 1. A basic fact for division uses a divisor from 1 to 9 and has a quotient from 1 to 9 . Using basic facts can help you divide larger numbers. \( 4 \div 4=1 \) \( 8+4=2 \) \( 12 \div 4=3 \) The next two basic facts with 4 as a divisor are: \( 16 \div 4=-40 \) \( +4= \) 2. Use patterns to divide by thinking of place value. \( 1,600 \div 40= \) ? \( 1,600 \div 40=1,600 \) ones +40 ones \( 1,600 \div 40=160 \) tens \( \div \) tens MyPath - Home EZ Pay \| myPayract Kentuachy: Departme_ Mathematics Rodrick Martin 01/13/25 6:26 PM W 4 - Variation and Percents Question 47, 4.4.C-19 HW Score: \( 70.63 \%, 44.5 \) of 63 points Points: o of 1 Save A 61 -year-old man has a maximum heart rate of 152 bpm (beats per minute) He plans an exercise program so that his heart rate will be between \( 75 \% \) and \( 90 \% \) of his maximum heart rate for at least 30 minutes a day, 3 days a week. Calculate the desired range of heart beats per minute for this exercise program. The minimum rate for this exercise program will be \( \square \) beats per minute The maximum rate will be \( \square \) beats per minute. (Round to the nearest whole number as needed) 19. Number Sense Explain how you know \( \frac{21}{100} \) is greater than \( \frac{1}{5} \). Without using paper and pencil, how would you find the sum of 9.7 and 4.4? Use \( \square \) to add 0.3 to 9.7 to make the whole number 10.0 , and then add \( 10+4.4 \). Finally, subtract \( \square \) to get the correct sum, \( \square \) (Type whole numbers or decimals.) 4. Using the standard algorithm, divide 8832 by 30 I\& The BarWell Construction Company has submitted a bid on construction of a new spa deck. If their \( \$ 9290 \) bid includes \( \$ 2440 \) for lumber, what percent of the bid was the lumber? The lumber was \( \square \% \) of the bid. (Round to the nearest whole number as needed.) Because of the coaster's features, there is both a minimum and maximum for the height range. People who are at the minimum height to ride are 2 feet 1 inch shorter than people who are at maximum height to ride the coaster. One-fifth of the maximum height is 15.4 inches. - What will the height range look like when placed on the sign? Justify your reasoning. C.

If the hotel has 150 rooms available each night, what was the occupancy rate for that week? The occupancy rate was \( \square \% \). (Round to the nearest whote number as needed.)
