if the base and height are equal
and the formula equals b x h = A^2
then u can make a formula b x b = 64
then u take the square root of 64
I’m not really sure but I would have to guess 4.5 because all of the other numbers don’t have decimals
Answer:
262.12mph and 419kph
Step-by-step explanation:
Given: It takes 4 hours and 15 minutes to fly from Orlando, Florida, to Boston, Massachusetts. The distance between the two cities is 1114 miles
To Find: the average speend of the plane in miles per hour, If every mile is approximately 1.6 kilometers, the speed of the airplane in kilometers per hour
Solution:
Distance between Orlando,Florida and Boston, Massachusetts
![\text{miles}](https://tex.z-dn.net/?f=%5Ctext%7Bmiles%7D)
Time taken to cover the distance
and ![15\text{minutes}](https://tex.z-dn.net/?f=15%5Ctext%7Bminutes%7D)
We know that,
![\text{Average Speed}=\frac{\text{Total Distance}}{\text{Total time}}](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20Speed%7D%3D%5Cfrac%7B%5Ctext%7BTotal%20Distance%7D%7D%7B%5Ctext%7BTotal%20time%7D%7D)
![=\frac{1114}{\frac{17}{4}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1114%7D%7B%5Cfrac%7B17%7D%7B4%7D%7D)
![=\frac{1114\times4}{17}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1114%5Ctimes4%7D%7B17%7D)
![\text{mph}](https://tex.z-dn.net/?f=%5Ctext%7Bmph%7D)
It is given that,
![1\text{mile}=1.6\text{kilometer}](https://tex.z-dn.net/?f=1%5Ctext%7Bmile%7D%3D1.6%5Ctext%7Bkilometer%7D)
therefore,
![1\text{mph}=1.6\text{kph}](https://tex.z-dn.net/?f=1%5Ctext%7Bmph%7D%3D1.6%5Ctext%7Bkph%7D)
Speed Of plane in Kilometers per hours ![=\text{speed in mph}\times1.6](https://tex.z-dn.net/?f=%3D%5Ctext%7Bspeed%20in%20mph%7D%5Ctimes1.6)
![419.4\text{kph}](https://tex.z-dn.net/?f=419.4%5Ctext%7Bkph%7D)
Speed of in miles per hour is
and Speed in kilometer per hour ![419.4\text{kph}](https://tex.z-dn.net/?f=419.4%5Ctext%7Bkph%7D)
Answer:
y - 4 = -8/7(x - 4)
Step-by-step explanation:
Point-Slope form: y - y₁ = m(x - x₁)
x₁ and y₁ would be the coordinates of the point (4,4).
m would be the slope -8/7.
Substituting these values:
y - 4 = -8/7(x - 4)
Answer:
3/2
