The concept that can be used in order to measure the given item is the ratio and proportion. The ratio of Nicole's height to her shadow at that particular time should be equal to the ratio of the height of the tower to its shadow. If we let x be the height of the tower then, the equation would be,
x/20 feet = 5 ft/80 inches
The units of the denominators should be equal to have a reasonable comparison, let us convert 80 inches to feet by dividing it by 12 to get the answer of 20/3 ft.
x/20 = 5/(20/3)
The value of x from the equation is equal to 15 ft.
Answer: 15 ft.
Answer:
The girl had 24 candies in her bag.
Step-by-step explanation:
Since, regarding the girl's candies, 4 of them were blue, 1/6 of them were grape, 1/4 of them were watermelon, 1/3 of them were cherry and 1/12 of them were sour apple, to determine how many candies were in her bag, the following mathematical calculation should be performed:
1/6 + 1/4 + 1/3 + 1/12 = X
2/12 + 3/12 + 4/12 + 1/12 = X
10/12 = X
12/12 - 10/12 = 2/12
2/12 = 4
1/12 = 2
2 x 12 = 24
Thus, the girl had 24 candies in her bag.

You have to add your like terms. So you would add 5e + (-2)e first. That would equal 3e. Next you would add 8f + (-12)f. That would equal -4f. You final answer would be 3e - 4f.
2.608 rounded to the nearest tenths = 2.6
