Answer:
$76.49 So, the discounted price of the CD player is $76.49.
Step-by-step explanation:
Answer:
h = p - l - w
Step-by-step explanation:
p = 4l + 4w + 4h Divide l, w, and h by 4
p = l + w + h Set the equation equal to h
h = p - l - w
Step-by-step explanation:
Since
varies directly as
we can write the relation as
![x = k\sqrt{y}](https://tex.z-dn.net/?f=x%20%3D%20k%5Csqrt%7By%7D)
where k is the constant of proportionality.
a) To solve for the k, we substitute the given values:
![5 = k\sqrt{13} = k(13)](https://tex.z-dn.net/?f=5%20%3D%20k%5Csqrt%7B13%7D%20%3D%20k%2813%29)
![\Rightarrow k = \dfrac{5}{13}](https://tex.z-dn.net/?f=%5CRightarrow%20k%20%3D%20%5Cdfrac%7B5%7D%7B13%7D)
b) The equation relation x and y can be written as
![x = \dfrac{5}{13}\sqrt{y}](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B5%7D%7B13%7D%5Csqrt%7By%7D)
c) When y = 9,
![x = \dfrac{5}{13}\sqrt{9} = \dfrac{5}{13}(3) = \dfrac{15}{13}](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B5%7D%7B13%7D%5Csqrt%7B9%7D%20%3D%20%5Cdfrac%7B5%7D%7B13%7D%283%29%20%3D%20%5Cdfrac%7B15%7D%7B13%7D)
Answer:
x=0.y=3
Step-by-step explanation:
5x-y=-3
y=5x+3
sub y=5x+3 into 6x+y=3,
6x+5x+3=3
11x=0
x=0
6(0)+y=3
y=3
The height of the plane when it gets to the tower would be 600 yards, which is greater than the height of the tower. Hence, <em>"the plane clears the tower with about 6 yards to spare." </em>
<u>Given</u><u> </u><u>the</u><u> </u><u>Parameters</u><u> </u><u>:</u>
- <em>Initial distance traveled = 1500</em>
- <em>Yards to control tower = 600</em>
- <em>Height of control tower = 198 feets = (198×3) = 594 yards </em>
If the rate of ascent of the airplane is proportional to the distance traveled, that is (1 yard length = 1 yard height gained).
Then after traveling 600 yards to the position of the control tower, then the height of the plane would be 600 yards
<u>Difference in height</u> :
- <em>Height of plane - Height of tower</em>
(600 yards - 594 yards) = 6 yards
Therefore, the most appropriate Statement is that, "<em>the</em><em> </em><em>plane</em><em> </em><em>clears</em><em> </em><em>the</em><em> </em><em>tower</em><em> </em><em>with</em><em> </em><em>about</em><em> </em><em>6</em><em> </em><em>yards</em><em> </em><em>to</em><em> </em><em>spare</em><em>.</em><em>"</em><em> </em>
