Answer:
13
Step-by-step explanation:
23-(12+6)+8
23-18+8
31-18
13
Answer:
2nd option
Step-by-step explanation:
Repeatedly divide by 2 until the value 1 is reached
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1 ← finish here
Then
32 = 2 × 2 × 2 × 2 × 2
Answer:
0.252 m
Step-by-step explanation:
At the fundamental frequency, a closed-end column has the same wavelength as an open-end column twice as long. Column B only needs to be half the length of Column A:
0.504 m/2 = 0.252 m
After this step:
1. 8+x=7 multiply both sides by -1
2. x=-7-8 move the constants to the right
3.x=-7-8 Calculate
4. x=-15
Question is not Proper.The Proper Question is given below.
∠P and ∠Q are complementary. m∠P = 52° and m∠Q = (3x + 2)°. Find the value of x. Show your work.
Answer:
Therefore the value of x is
![x=12](https://tex.z-dn.net/?f=x%3D12)
Step-by-step explanation:
Given:
∠P and ∠Q are complementary.
m∠P = 52° and
m∠Q = (3x + 2)°.
To Find:
x = ?
Solution:
Complementary Angles:
Two angles are Complementary when they add up to 90 degrees.
Example 40° and 50° are Complementary Angles.
If 'x' and 'y' are Complementary Angles the we have
![x+y=90\°](https://tex.z-dn.net/?f=x%2By%3D90%5C%C2%B0)
Here, ∠P and ∠Q are complementary.
![\angle P+\angle Q=90\°](https://tex.z-dn.net/?f=%5Cangle%20P%2B%5Cangle%20Q%3D90%5C%C2%B0)
Substituting the values we get
![52+3x+2=90\\3x=90-54=36\\\\x=\dfrac{36}{3}=12](https://tex.z-dn.net/?f=52%2B3x%2B2%3D90%5C%5C3x%3D90-54%3D36%5C%5C%5C%5Cx%3D%5Cdfrac%7B36%7D%7B3%7D%3D12)
Therefore the value of x is
![x=12](https://tex.z-dn.net/?f=x%3D12)
