Answer:
4.2mm
Step-by-step explanation:
This are two similar triangles.
Comparing the two:
8/3 = (7+x)/x
Cross multiplying
8x = 3 (7+x)
8x = 21 + 3x
8x - 3x = 21
5x = 21
Dividing by 5
X = 21/5
X = 4.2mm
slope (M) = (y2-y1)/(x2-x1)
x1 =3, y1= -5, x2 = 5, y2=5
= (-5-5) / (3-5) = -10/-2 = 5
M=5
Answer:
Step-by-step explanation:
8 in × (1 ft)/(12 in) = ⅔ ft
36 ft × 58 ft × ⅔ ft = 1392 ft³
1392 ft³ × (1 yd³)/(27 ft³) ≅ 52 yd³
52 yd³ × $123/yd³ = $6396
