Find x, y, and z.
Multiple choice answers are below!
Answers
Answer:
The correct answer is B. x ≈ 4.5, y = 5, z = 9
Step-by-step explanation:
1. We will use the Pythagorean theorem for solving for x, this way:
x² = 6² - 4²
x² = 36 - 16
x² = 20
x = √20
x = 2 √5 = 4.47 ≈ 4.5
2. For solving for y, we will do it this way:
There are only two possible options: y = 5, included in answer B or y = 9 as it is defined on answer C.
If we review it carefully, we will realize that y = 9 is not accurate because as we can see in the graph y + 4 = z and in this specific case, 9 + 4 ≠ 5 but it's true that 5 + 4 = 9.
Because of this reason, the correct answer is B. x ≈ 4.5, y = 5, z = 9

Answers
large cylinder: height = 3 ft ; diameter = 2 ft
cylinrical cup: height = 1/2 ft ; diameter = 1/4 ft
Volume of a cylinder = π r² h
large cylinder volume = 3.14 * (1ft)² * 3ft = 3.14 * 1ft² * 3ft = 9.42 ft³
cylindrical cup volume = 3.14 * (0.125ft)² * 1/2 ft = 3.14 * 0.015625ft² * 0.5ft = 0.0245 ft³
9.42 ft³ ÷ 0.0245ft³ = 384.489 cups

x/18 = 4.5
You multiply both sides by 18 to get the x by itself
x = 4.5 • 18
You simplify this
x = 81
26. x= 81
28. x= 980
30. x=2

The total price of the car is $26901.20
Step-by-step explanation:
It is given that,
- The cost of the new car = $21,920.00
- The tax percent for the cost of the car = 17.25%
- He also purchases an extended warranty for the car = $1,200.00
To find the total price of the car :
Total Price = cost of the car + Tax cost + warranty cost.
The cost of the car and warranty cost are already given. So, we need to calculate the Tax amount paid for the car.
Tax amount = 17.25% of $21,920.00
⇒ 17.25/100 × 21,920.00
⇒ 0.1725 × 21,920
⇒ 3781.2 dollars.
Therefore, the cost of tax is $3781.2
Now, coming to the total price of the car,
Total Price ⇒ 21,920.00 + 3781.20 + 1200.00 = 26901.20 dollars.
The total price of the car is $26901.20
