The paper is 16 cm by 34 cm to start with, so we started with area
.. (16 cm)*(34 cm) = 544 cm^2
A circle of diameter 16 cm has been removed. The area of that circle is
.. π*(d/2)^2 = 3.14*(16 cm/2)^2 = 200.96 cm^2
Then the area of the paper that remains is
.. 544 cm^2 -200.96 cm^2
.. = 343.04 cm^2
Answer:
Step-by-step explanation:
2 and 38/45 square yards can be sanded in 3.2 hours.
Step-by-step explanation:
1/2 of an hour is 30 minutes. so 4/9 for every 30 minutes. 1 hour is 8/9. So 3 2/10 would be 3 hours =24/9=2 6/9 and 2/10 would be ( if 5/10 is 30 minutes then 2/10 is 12 minutes.) 8/9 x 1/5 = 8/45. (24 x 5 = 120) 120/45 + 8/45 is 128/45 = 2 38/45
Answer:
102
Step-by-step explanation:
These angles are congruent due to corresponding angles thm
3x + 21 = 6x - 60
3x - 6x = -60 - 21
-3x = -81
x = 27
3x + 21
3(27) + 21
81 + 21

Answer:
B-a population growth of 3% each year
Step-by-step explanation:
The 1.03 would mean that the exponential function is increasing by 3% every year because it is 0.03 units above 1.
