2 decimal places for regular . 3.14
Answer:
64 : 729
Step-by-step explanation:
Ratio of surface area
= (ratio of linear dimensions) ^2
= 1.6^2 : 5.4^2
= 256 : 2916
= 64 : 729
Answer:
10
Step-by-step explanation:
Each pie was cut into 6 pieces. 6 x 10= 60.
Answer: a) 0.2500
b) 0.1875
c) 0.4375
d) 1.414
e) 0, x/2
f) 1.3333
g) 0.4714
h) 2
Step-by-step explanation: see attachment below
Δ ABC: ∠A = 32° ; a = 19 (side a opposed to angle A)
and side b = 12 (opposed to Angle B)
Law of sine's
:
(sin A)/19 = (sin B)/12, but sin A = sin 32° = 0.53
0.53/19 = (sin B)/12
and sin B = (0.53 x 12) / 19 → sin B = 0.335.
Calculate ∠ B:
sin B = 0.335. → sin⁻¹(0.335) = 19.57° ≈ 20°
∠ A = 32°, ∠B ≈ 20° and ∠C = 180° -32°-20° = 128°
Now that we have got the 3 Angles, let's find c, the 3rd side of the Δ
sin 32/19 = sin 128/c
0.03 = 0.788/c and c ≈ 26
+a = 19, b = 12 an c = 26
