Answer: Option #4: the 0.2 could be changed to 2.
Explanation:
The table is designed to make the concept of percentages more understandable. The table first allocates the total amount of 70 in terms of its "fifths," or 20% parts. Then it expresses these parts in the last row of the table, showing that 20% of 70 is 14 and all the five parts sum up to 70 again.
Now, Mikel is supposed to express 40% of the amount. So she writes (incorrectly): 0.2 * 14. This statement needs to be changed to 2 * 14 (two times 14 = 28), to correspond to 2 times 20%, or 40% of 70.
This is reflected in the last (fourth) option "The 0.2 in the expression could be changed to 2."
Option #3 is incorrect because changing 14 to 70, will result in an incorrect number (2.8).
Options 1 and 2 are similarly incorrect (as can be easily verified)
Add 0.5 to each side so you have fabric for the seams and your new numbers are 3 ft and 4 ft
find the area by multiplying 3*4 and get 12 ft
1 yard = 3 feet
12/3= 4 yards
You would need 4 square yards of fabric
Answer:
q8+p6=14
Step-by-step explanation:
6864x6=41184..............
Surface area of bin:
A = 2(pi)rh + 2(pi)r^2
Assuming you use 3.14 for pi:
A = 2(3.14)(9)(30) + 2(3.14)(81)
A = 2204.28ft^2
