The least precise measurement of the perimeter of the window is 231.30
Step-by-step explanation:
The least price measurement mean a value with the least number of significant figures.calculate the perimeter in this case as;
Perimeter of a rectangle = 2(l+w) where l is the length and w is the width
Perimeter= 2(81.47 + 34.2)
Perimeter=2(115.67)
Perimeter=231.34
Perimeter=231.30(4 significant figures)
Answer:
Third graph, I took the test
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
If you divide their time by 100 you will get the amount of time it takes the student to run 1 meter.
Ex. Time is 20 seconds.
20/100
0.2 meters/second
1. find the LCD of 3 and 4 (12). so now your fractions are 5 4/12 and 3 9/12 perimeter is 2l + 2w so 2 (5 4/12) + 2( 3 9/12) = 10 4/12 + 7 6/12 = 17 10/12 or 17 5/6. this is reasonable because that the average perimeter of a sandbox.
2. LCD again is 12, so the fractions are 5 10/12 and 2 1/12. turn those into mixed fractions and get 70/12 and 25/12. 45/12 or 3 3/4. So she babysits 3 3/4 hours during the week.
3. The LCD for this is 8. now the fractions are 2/8 and 1 7/8 or 15/8. add 15/8 and 2/8 to get 17/8 or 2 1/8. He is using a total of 2 1/8 cups of flour.
4. 0.2
5. 0.054
6. 0.024
Simple enough:
Solve for V:
V/2 + 6 = 14
Put each term in V/2 + 6 over the common denominator 2: V/2 + 6 = V/2 + 12/2:
V/2 + 12/2 = 14
V/2 + 12/2 = (V + 12)/2:
(V + 12)/2 = 14
Multiply both sides of (V + 12)/2 = 14 by 2:
(2 (V + 12))/2 = 2×14
(2 (V + 12))/2 = 2/2×(V + 12) = V + 12:
V + 12 = 2×14
2×14 = 28:
V + 12 = 28
Subtract 12 from both sides:
V + (12 - 12) = 28 - 12
12 - 12 = 0:
V = 28 - 12
28 - 12 = 16:
Answer: V = 16
