Answer:
look at the graph i made with desmos, i just plugged the equation in.
Step-by-step explanation:
Step-by-step explanation:
N6000×5=N30000
1)N30000-N25000=N5000
2)N5000÷N25000×100℅=20℅
Answer:
The car is going up at a speed of 22.5 mph
Step-by-step explanation:
In this question, we are asked to calculate the speed of a moving car which started moving at an initial velocity for a specific period of time.
To calculate this, we use one of the basic equations of motion;
v = u + at
Where v is the final velocity, u is the initial velocity and t is the time
From the question, we can identify the parameters as follows;
v = ?
u = 10mph
a = 2.5t mph per second for 5 seconds.
Hence a here would be 2.5 * 5 = 12.5
Now, let’s put these values in the equation
v = 10 + 12.5
v = 22.5 mph
Since we know that percentages and decimals go by decimal place we can solve this. For Example, 10% is just 0.1, so if we apply this to the questions we can solve them
1) 49%
2)16%
3) Equal
4)12%
5)1.2
6)31/50
7)50 1/4
8)1/8
