Given:
6 | 1 means a score of 61.
The scores of the students from the stem-and-leave are
61, 62, 63, 71, 73, 75, 77, 78, 78, 79, 82, 82, 84, 85, 89, 95, 96, and 99.
Required:
We need to find the lowest score in the 80s, the highest score overall, and the number of students who scored in the 70s.
Explanation:
The scores in the 80s are
82, 82, 84, 85, and 89.
The smallest score is 82.
The lowest score in the 80s is 82.
T
Answer:
11 meters
Step-by-step explanation:
Using the Pythagorean Theorem
a^2 + b^2 = c^2
a^2 + 60^2 = 61^2
a^2 + 3600 = 3721 (subtract 3600 from both sides)
a^2 = 121 (square root both sides so a^2 becomes a)
a = 11
Answer:
11) 140/8 = 17.5
12) 38/3 = 12.667
13) 114/9 = 12.667
14) 7/2 = 3.5
15) 14/9 = 1.556
Step-by-step explanation:
To solve each problem you need to multiply the numerator by the whole number:
11) 7*20 = 140
12) 2*19 = 38
13) 6*19 = 114
14) 1*7 = 7
15) 7*2 = 14
Next, you put these numbers back into their corresponding numerators and divide:
11) 140/8 = 17.5 (You can simplify this fraction to 70/4 if needed)
12) 38/3 = 12.667 (This answer is rounded to the thousandths place)
13) 114/9 = 12.667 (This answer is rounded thousandsths place)
14) 7/2 = 3.5
15) 14/9 = 1.556 (This answer is rounded thousandths place)
**These are the improper fractions written as mixed ones** :
11) 17 1/2
12) 12 2/3
13) 12 2/3
14) 3 1/2
15) 1 5/9
I hope this helps!
