Answer:
23.76%
Step-by-step explanation:
1. 78 = 0.15x
78 / 0.15 = x
520 = x.....so 78 is 15% of 520
2. | 3x - 2 | = 8 | x + 1 | = 1
3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2
ur answer is : x = -2
3. 3y - 4x + 5 = 0
3y = 4x - 5
y = 4/3x - 5/3
slope = 4/3
Keeping in mind that x = rcos(θ) and y = rsin(θ).
we know the magnitude "r" of U and V, as well as their angle θ, so let's get them in standard position form.


Answer:
Hello! answer: area is 6 cm2
Step-by-step explanation:
Triangle area formula: base × height ÷ 2 or base × height × 1/2 so...
12 × 16 = 192 192 ÷ 2 = 96
12 ÷ 4 = 3
16 ÷ 4 = 4
3 × 4 = 12 12 ÷ 2 = 6 therefore the area is 6 hope that helps!
