Step-by-step explanation:
43. A "Square" cornfield, which means all 4 sides has the same lenght BxH
164.000 ft^2=404.96 NO
156.816 ft^2=396 Yes
174724 ft^2=418 Yes
215908 ft^2=464.66 NO
44. it's the same here, if the area is 81. then each side of the square is 9
1st figure: it has 12 sides x9 =108
2nd figure: it has 10 sides x9=90
3rd figure: has also 12 sides x9=108
45. 13^3= 13x13x13 = 2197
46. 25^2= 25x25 = 625
47. 15^3= 15x15x15 = 3375
48. 34^2= 34x34 = 1156
49. 5 root121= 5 (11)=55
50. -6.root36= - 6 (6)= -36
51. 10 root3 (8) = 10(2) = 20
52. -4. root 144= -4(12) = -48
Answer:
2x + 3y = 12
Step-by-step explanation:
Standard form is Ax + By = C, A, B and C must be intergers, cannot be fractions or decimals
y = -2/3x + 4 First we want to get rid of the fractions. There is only one, so if we multiply both sides by 3 that should do it.
3y = -2x + 12 Now make the constant be on one side by itself
2x + 3y = 12
7.70 and 7.700 they are all the same since the 7 tenths are still in its place
Answer:
2011
Step-by-step explanation:
Here is the formula.
A = Final Value
P = Starting Value
R = Rate
N = Time in Years
A = 8,000,000,000
P = 5,400,000,000
R = 0.0195
N = Time in Years
Solve for n.
20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.
