For triangles, area is 1/2 base times height
8. Base 15 1/4 and height 18. Base and height can be flipped around to make the math easier, so 1/2(18)(15 1/4) = 9(15 1/4) = 9(61/4) = 549/4= 137 1/4 sq inches
9. Base 13 and height 11. Area = (1/2)(13)(11)= (13/2)(11) = 143/2 = 71 1/2 sq inches
10. Same thing again. Base = 30, height = 20, so area = (1/2)(30)(20) = 15(20) = 300 square km.
11. Base = 8, height = 5, so (1/2)(8)(5)= 4(5)= 20 square feet.
12. Base = 5, height = 3, so area = (1/2)(5)(3)= (5/2)(3)= 15/2; for 200 tiles we would take (15/2)(200)= 15(100) = 1500 square cm
13. Monica forgot to multiply base and height by 1/2.
0.0505(35) = 1.7675...rounds to 1.77
157 - 35 = 122
0.0305(122) = 3.721...rounds to 3.72
the fee is : 1.77 + 3.72 = $5.49
Answer:
0.4
Step-by-step explanation:
3(x^2+6x+8)
3(x+4)(x+2)
The answer is D
3/4 divided by 1/10
15/2=7.5 miles/hr
