Answer:
$12.09
Step-by-step explanation:
formula; Y= kx
where; y = $24.18
x = 2 books
k = constant of proportionality
Step 1. Do the equation based on the data given
Y = kx
$24.18 = k2
Step 2. Compute the mathematical equation. Divide both sides by 2 to eliminate coefficient in the variable.
<u>24.18 =k2</u>
2
k = $ 12.09 is the constant of proportionality cost in dlooars per book
The total distance Tracy traveled was 15,000 feet assuming each unit represents 1,000 feet.
<h3>How to calculate the total distance?</h3>
The total distance is the sum of all the distance between stops.
Partial distances:
- Home to stop 1: 2,000 feet
- Stop 1 to 2: 4,000 feet
- Stop 2 to 3: 5,000 feet
- Stop 3 to 4: 4,000 feet
- Total distance: 15,000 feet
However, the real distance would be 10.63 units based on the locations in the grid.
- d=√(0−8)^2+(7−0)^2
- d=√8^2+7^2
- d=√64+49
- d=√113 =10.63 units

Answer:
Step-by-step explanation:
<h3>Given</h3>
- ΔXYZ with m∠Z > m∠X + m∠Y
<h3>Options</h3>
<u>m∠X + m∠Z < 90°</u>
- incorrect, the sum of these two angles should be > 90°
<u>m∠Y > 90°</u>
- incorrect, it should be < 90°
<u>∠X and ∠Y are complementary</u>
- incorrect as angle Z is greater that the sum of angles X and Y, then sum of three angles would be greater than 180°
<u>m∠X + m∠Y < 90°</u>
- correct, this is the only possible option
