7 it’s 7 because I did this already and remembered the answer to it
f(x) = e²ˣ⁻¹
f⁻¹(x) = ln(2x - 1)
The speed of the plane will be equal to 240 Mph.
<h3>What is speed?</h3>
Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
Given that:-
- Mattie Evans drove 350 miles in the same amount of time that it took a turbo propeller plane to travel 1200 miles.
- The speed of the plane was 170 mph faster than the speed of the car.
The speed of the plane will be calculated as:-
Let the speed of the car will be x mph so the speed of the plane will be
(x + 170)
Now time for the plane:-
Tp = Dp / Sp
Tp = 1200 / (x+170)
Now time for the car:-
Tc = Dc / Sc
Tc = 350 / x
It is given that time taken by both the plane and the car are equal:-
Tp = Tc
1200 / x+170 = 350 / x
1200x = 350x + 59500
850x = 59500
x = 59500 / 850
x = 70mph
The speed of the plane will be calculated By:-
Sp = x + 170 = 70 + 170 = 240 Mph
Therefore the speed of the plane will be equal to 240 Mph.

Answer:
Pizza: 27°
Curry: 108°
Fish and Chips: 63°
Kabab: 27°
Other: 135°
Step-by-step explanation:
Frequency 40 = 360°
Pizza (3) = 
* 360° = 27°
Curry (12) = 
* 360° = 108°
Fish and Chips (7) = 
* 360° = 63°
Kabab (3) = * 360° = 27°
Other (15) = 
* 360° = 135°
27 + 108 + 63 + 27 + 135 = 360
