I am pretty sure it would be $4.10 per gallon. I hope this got to you in time.
Answer:
15) 3.2
17) 13.4
Step-by-step explanation:
To find the missing lengths, you need to use the Pythagorean theorem:
a² + b² = c²
In this form, "c" represents the length of the hypotenuse and "a" and "b" represent the lengths of the other two sides.
You are trying to find one of the side lengths (not the hypotenuse) in 15). To find the other length, you can plug the other values into the equation and simplify to find "b".
15) a = 4.1 c = 5.2
a² + b² = c² <----- Pythagreom Theorem
(4.1)² + b² = (5.2)² <----- Plug values in for "a" and "c"
16.81 + b² = 27.04 <----- Raise numbers to the power of 2
b² = 10.23 <----- Subtract 16.81 from both sides
b = 3.2 <----- Take the square root of both sides
You are trying to find the hypotenuse in 17). Since you have been given the lengths of the other sides, you can plug them into the equations and simplify to find "c".
17) a = 4.4 b = 12.7
a² + b² = c² <----- Pythagreom Theorem
(4.4)² + (12.7)² = c² <----- Plug values in for "a" and "b"
19.36 + 161.29 = c² <----- Raise numbers to the power of 2
180.65 = c² <----- Add
13.4 = c <----- Take the square root of both sides
Answer: 42 feet.
Step-by-step explanation:
Let's call the shorter side: x
Based on the information given in the problem, you know that:
Longer side:
Hypotenuse:
- Apply the Pythagorean Theorem:
Where<em> a</em> is the hypotenuse and <em>b</em> and <em>c</em> are the legs.
- Substitute values. Therefore, you obtain:
- Solve for x. Keep on mind that:
Then:
Therefore, the length of the shorter leg is 42 feet.
Answer:
It is about 3.18 inches
Step-by-step explanation:
54 divide by 17 equals to 3.17647058824
estimate 3.17647058824 to hundredth place equals to 1.18

Answer:
$10,371.24
Step-by-step explanation:
Assuming the sales tax is applied only to the car price, the total is ...
$9400×1.065 +225 +75.25 +59.99 = $10,371.24
_____
The car price with tax is 9400 + 6.5%×9400 = 9400×(1 + .065).
