Answer: D

Sound waves with higher amplitudes sound louder than sound waves with lower amplitudes. Constructive interference will make a sound louder while destructive interference will make a sound quieter. Two waves that add together may have different frequencies.

Step-by-step explanation:

The diameter of the circle is 4 inches so its radius r is 2 inches. The area of the circle is

$A = \pi r^2 = \pi(2\:\text{in})^2 = 12.57\:\text{in}^2$

The circumference C of the circle is

$C = 2\pi r = 2\pi(2\:\text{in}) = 12.57\:\text{in}$

Can I get help with this please

Answer:

3) 1 5/6 mi

4) a. 4 cm, 6 ft

b. 6.4 cm, 9.6 ft

c. same as part a

Step-by-step explanation:

3) Each of the given distances appears twice in the sum of side measures that is the perimeter. Hence by walking the perimeter twice, Kyle walks each of the given distances 4 times. His total walk is ...

4×1/3 + 4×1/8 = 4/3 + 4/8

= 1 1/3 + 1/2 = 1 2/6 + 3/6

= 1 5/6 . . . . . miles

___

4) Since the figure is rectilinear (all angles are right angles, and all sides are straight lines), the sum of partial dimensions in one direction is equal to the whole dimension in that direction.

a. 8 cm = 4 cm + x

8 cm - 4 cm = x = 4 cm

The distance in the room is ...

(4 cm)×(1.5 ft/cm) = 6 ft

b. 10.3 cm = 3.9 cm + y

10.3 cm - 3.9 cm = y = 6.4 cm

The distance in the room is ...

(6.4 cm)×(1.5 ft/cm) = 9.6 ft

c. The answer to part b was obtained in the same way as the answer to part a. The unknown dimension is the difference of given dimensions. The actual length in the room is the model length multiplied by the inverse of the scale factor.

Use the expression 5a – 2b – 3 + 2b – 6a.

ella [17]

Answer:

5a + (-6a) + (-2b) + 2b + (-3) = -a -3 or -(a + 3) so first answer is correct because -(a + 3) is the same as -(3 + a)
