w=7.5
Step-by-step explanation:
area of triangle is 6x5=30/2= 15 and then you divide 15 which 7.5
Answer:
The correct answer is E. Neither the frequency nor the wavelength is affected. Explanation: The wave frequency does not affect the speed of that wave. An increase in frequency of a wave causes a decrease in wavelength while the wave speed remains the constant. The speed of the waves is significantly higher at higher tensions.

Answer:
5%
Step-by-step explanation:
The equation for simple interest rate is as follows:
A = P(1+rt)
A = final amount
P = initial principal amount
r = annual interest rate
t = time (in years)
So, we need to plug everything in and solve for r:
The final amount is equal to $875 plus the interest of $131.50.
A = 875 + 131.50 = 1006.50
Now, plug everything in:
1006.50 = 875( 1 + r(3))
Solve:
1 + 3r = 1.15028571 Divide 1006.50 by 875
3r = 0.15028571 Subtract 1 from 1.15028571
r = 0.050 Divide by 3
The simple interest rate would be 5%. I converted the r to a percent by multiplying 0.050 by 100.

Answer:
A) 18%
Step-by-step explanation:
Find percent change by subtracting to find the change, then put that over the original amount and times by 100.
79 - 65 is 14
change/original is
14/79
= .177
Then times 100 to make the decimal into a percent.
0.177×100 is 17.7%
which rounds to 18%.
