Answer:
90 : 54 : 36
Step-by-step explanation:
Add the ratios: 5 + 3 + 2 = 10
Divide 180 kg by 10: 180 ÷ 10 = 18
Multiply each number of the ratio by 18:
5 × 18 : 3 × 18 : 2 × 18
⇒ 90 : 54 : 36
Answer:
(0, -2) and (2, 0)
Step-by-step explanation:
The solution to a systems of equations is when the x and y values are equal for two equations. This can also been seen as when the two equations intersect. So by looking at the graph you see the line and the circle intersect at the point (2, 0) and (0, -2) which are going to be the two solutions to the systems of equations.
So this is not too hard, as with any math problem we write what we know.
Starting speed: 80km/h
Time from P to Q: 2.5h
Increase in speed: 20km/h (25% is dividing by 4)
Distance from Q to R: 150 kilometers
So let's find the speed and distance for both legs of the trip.
Speed for P to Q: 80km/h
Distance from PtoQ: 200km (2.5h * 80km/h)
Speed from Q to R: 100km/h (80 +20)
Distance from QtoR: 150km.
Now we multiply the speeds by their respective distances add them and then divide by the total distance.
((80 *200) + (100 * 150))/350 = ~88.57143
If they are decreasing at 3% , net = 100% - 3% = 97%
Reduction rate = 97% = 0.97
After 1st year = 1200*0.97
After 2nd year = 1200*(0.97)*(0.97) = 1200*(0.97)²
After 3rd year = 1200*(0.97)*(0.97)*(0.97) = 1200*(0.97)³
After x years, = 1200(0.97)ˣ
Therefore, function f(x) = <span>1200(0.97)ˣ</span>
Answer:
1484
Step-by-step explanation:
L = Length . 212
W= Width . 7
A= Area.
