Since one pound is 16 ounces, it would cost .3*16, or $4.80 to buy one pound of peanuts. $5 is enough and there would be $0.20 left over.
Question 4: line passes thru (4, -2) with slope m = 2
Let's use the slope-intercept form:
y = mx + b
-2 = 2(4) + b
-2 = 8 + b so b = -10
The equation of this line is y = 2x - 10.
Answer:
x = 5
Step-by-step explanation:
since it is isoscles,
5x-8 = 2x+7
reduce
3x = 15
x = 5
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
