Answer:
0.5 + 0.06 + 0.004 in expanded form.
Step-by-step explanation:
1. 75% increase
2. 30% decrease
3. 80% increase
4. 25% decrease
Let x be the width , then the height = 4x
Area of this right triangle is x(4x)/2
Area = 4x²/2 = 32 m²
x² = 16
x = 4 m. If the width is 4 m, the height = 4 x 4 = 16 m
Angle B = 38° (option C)
This is because vertical angles are congruent
Hope this helps!! :)
Circumference of the outer circle = 2πr = 2π(6) = 12π
circumference of the outer arc = 120/360 x 12π = 12.57cm
circumference of the inner circle = 2πr = 2π(5) = 10π
circumference of the inner arc = 120/360 x 10π = 10.47 cm
Difference in length = 12.57 - 10.47 = 2.1cm (1 d.p.)
Answer: 2.1cm
