Answer:
Yes He should stop for Gas
Step-by-step explanation:
Step one:
given data
total distance left=429.5miles
we want to find the amount of gallons the car will consume for 429.5 miles
we are told that for 33 miles traveled the car will consume 1 gallon of gas
hence for 429.5 miles the car will consume x gallons
cross multiply we have
x=429.5/33
x=13.0gallons
This shows that the tank will be empty for a 429.5 miles.
It is the square of the input value
Answer:
The answer to your question is below
Step-by-step explanation:
Data
Equation 25x² + 64y² = 1600
Process
1.- Divide all the equation by 1600
25x²/1600 + 64y²/ 1600 = 1600/1600
-Simplify
x²/64 + y²/ 25 = 1
2.- Equation of a horizontal ellipse
3.- Find a, b and c
a² = 64 a = 8
b² = 25 b = 5
-Calculate c with the Pythagorean theorem
a² = b² + c²
-Solve for c
c² = a² - b²
-Substitution
c² = 8² - 5²
-Simplification
c² = 64 - 25
c² = 39
-Result
c = √13
4.- Find the center
C = (0, 0)
5.- Find the vertices
V1 = (-8, 0) V2 = (8, 0)
6.- Find the foci
F1 = (-√13, 0) F2 = (√13, 0)
<span>n Billy's class, 75% of his classmates had brown hair. 18 of his classmates had brown hair. What's the total number of students in his class?</span>
That's false.
For similar triangles, corresponding angles are congruent.
Corresponding sides are in the same ratio but rarely congruent.
(They're congruent only if the ratio is ' 1 ', i.e. the triangles are congruent
as well as being similar.)
