The article "Measurement of Complex Permittivity of Asphalt Paving Materials" (J. Shang, J. Umana, et al., Journal of Transporta

tion Engineering, 1999:347– 356) compared the dielectric constants between two types of asphalt, HL3 and HL8, commonly used in pavements. For 42 specimens of HL3 asphalt the average dielectric constant was 5.92 with a standard deviation of 0.15, and for 37 specimens of HL8 asphalt the Navidi-3810214 book November 11, 2013 14:8 432 CHAPTER 6 Hypothesis Testing average dielectric constant was 6.05 with a standard deviation of 0.16. Can you conclude that the mean dielectric constant differs between the two types of asphalt?

Which of the following equations could be solved to determine the length of RS?
stich3 [128]

Answer:

\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

Step-by-step explanation:

Given:

S = 52.5°

s = QR = 7

Q = 80°

q = RS = ?

Required:

Equation that could be used to find the length of RS

Solution:

We would need the law of Sines which is given as:

\frac{Sin(A)}{a} = \frac{Sin(B)}{b} = \frac{Sin(C)}{c}

Applying the Law of Sines, we would have the following equation:

\frac{Sin(Q)}{q} = \frac{Sin(S)}{s}

Plug in the values

\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

Therefore, the equation that can be used to determine the length of RS is \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

At Pizza Pi, 20% of the pizzas made last week had extra cheese. If 50 pizzas had extra cheese, how many pizzas in all were made
Mekhanik [1.2K]

Answer:

250 pizzas

Step-by-step explanation:

We can use the formula 50 = 20/100x. We multiply both sides by 100 to get 5000 = 20x. Now, we divide both sides by 20 to get 250 = x. That means 250 pizzas were made last week.
