Answer:
h = 12.5
Step-by-step explanation:
Simplifying
h + 3h + 4h = 100
Combine like terms: h + 3h = 4h
4h + 4h = 100
Combine like terms: 4h + 4h = 8h
8h = 100
Solving
8h = 100
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by '8'.
h = 12.5
Simplifying
h = 12.5
Answer:
87.471
Step-by-step explanation:
Given that scores for test, quiz, final exam , average quizzes.
There are weight given as 55% for quiz, 30% for homework, 5% Final Exam 10% Tests:
Now to calculate the student final grade, we can use weighted average method.
Final exam average
67
90
44
29
100
100
100
75.71428571
Use the averages to find:
Score Weight Score*weight
Quizzes 90 55% 49.5
Homework 85 30% 25.5
Tests 75.71 10% 7.571
final exam 98 5% 4.9
total 87.471
Hence answer is 87.471
Answer:
1199.52
Step-by-step explanation:
714/x=100/168
(714/x)*x=(100/168)*x - we multiply both sides of the equation by x
714=0.5952380952381*x - we divide both sides of the equation by (0.5952380952381) to get x
714/0.5952380952381=x
1199.52=x
x=1199.52
Step-by-step explanation:
a) determine the rate in km/L
==> 9.5 L/100km = 10.526316 km/L
b) how far can the car travel with 475L petrol
==> 0.210526315789473km/l
c) how many litres of petrol do they need to travel 350 km
==>Liters per km (l/km)2.86×10-3
Liters per 10 km (l/10 km)0.03
Liters per 100 km (l/100km)0.29
Kilometer per liter (km/l)350
Answer: y = 5/2x -2
Step-by-step explanation:
parallel = same slope so the slope of the new line is 5/2
y+2 = 5/2(x-0)
y = 5/2x -2
