The pitch depends on the value of frequency. The frequency can be calculated using this formula:
Frequency = wave speed / wavelength
where wave speed = 343.00 m/s
wavelength = 0.77955 m
Frequency = 343.00 m/s / 0.77955 m
= 434.00 s^-1
Therefore the pitch is low since the frequency is also low.
Answer:
You have
21
dimes and
7
quarters.
Explanation:
Let
x
be the number of quarters, and
3
x
the number of dimes.
The amount of money you have can be written as
0.25
x
+
0.1
⋅
3
x
=
3.85
.
Now isolate
x
to find the number of quarters:
0.25
x
+
0.1
⋅
3
x
=
3.85
0.25
x
+
0.3
x
=
3.85
0.55
x
=
3.85
x
=
3.85
0.55
=
7
=
the number of quarters.
Then multiply by three to get the number of dimes:
7
⋅
3
=
21
7

Answer:
168 in³
Step-by-step explanation:
Given that :
Container in the shape of a Right rectangular prism has the following dimension :
Length, L = 14 inches
Width, W = 6 inches
Height , H = 4 inches
The volume, V of a rectangular prism is given by : length * width * height
V = width * height * length
V = 14 * 6 * 4 = 336 inch³
Since container is half filled with sand :
Volume of sand in container = total volume / 2 = 336 / 2 = 168 inch³
I think it's 25 because you just have to subtitute f with 77 so 77 minus 32 and you get 45. then 5 time 45 divided by 9. so it's 25
Answer:
See below ~
Step-by-step explanation:
<u>Question 1</u>
⇒ The given angles are supplementary (add up to 180°)
⇒ 6x + 6 + 8x - 22 = 180
⇒ 14x - 16 = 180
⇒ 14x = 196
⇒ x = 14
============================================================
<u>Question 2</u>
⇒ The given angles are complementary (Add up to 90°)
⇒ 3x + 5 + 40 = 90
⇒ 3x + 45 = 90
⇒ 3x = 45
⇒ x = 15
