1. A= a²
2. Find the square root of the area to find the length of its side length.
3. √81= 9
√89= 9.43
4. For the first square, the side length is a rational number because 9 is a whole number. For the second square, the side length is irrational because the decimals do not repeat themselves.
Hey there,
Your question states: <span>To rent a midsize car for one day, Speedy charges a flat rate of $41 plus an additional fee of $0.10 per mile driven. Use your function from the previous question, to predict the total cost of renting a car for one day, given that you plan to drive the car 200 miles.
.10/200
20+41= 61
61 would be your correct answer.
Hope this helps.

Answer:
P_he = 562.5 mmHg
P_ne = 1068.75 mmHg
P_ar = 618.75 mmHg
Step-by-step explanation:
Formula for partial pressure is;
Partial pressure = mole fraction × total pressure
Mole fraction of Helium(He); x_he= 1/(1 + 1.9 + 1.1) = 1/4 = 0.25
Mole fraction of Neon(Ne); x_ne = 1.9/(1 + 1.9 + 1.1) = 1.9/4 = 0.475
Mole fraction of argon; x_ar = 1.1/(1 + 1.9 + 1.1) = 1.1/4 = 0.275
Thus;
Partial pressure of He;
P_he = 0.25 × 2250
P_he = 562.5 mmHg
Partial pressure of Ne;
P_ne = 0.475 × 2250
P_ne = 1068.75 mmHg
Partial pressure of Ar;
P_ar = 0.275 × 2250
P_ar = 618.75 mmHg
