Good luck to Jonathan. I hope he gets his sport set soon.
So, I didn't quite understand your question clearly, but I'll try my best to answer it.
So, the first question is quite simple: Did the runner have a % decrease in his time or an increase.
Well, 7:45 is minor than 5:51. So, his time decreased.
2nd question:
The percent of change. Well, first things first 7:45 has 2 different units, wich are minutes and seconds, I suppose. Same goes for 5:51.
So let's put everything in seconds. multiply both the 7 and 5 for 60(for every minute has 60 seconds.)
That means:
7*60= 420+45 = 465.
5*60=300+51=351.
Now, let's do the math itself:
465 -> 100%
351 -> x%
Is equal to about 75,5%
How much did it decrease then?
(75,5-100)%= 24,5%, approximately
So first you plug 6 into the equation which is 4(6)-10.
Using PEMDAS, you solve what’s in the parenthesis first and you get 24-10.
24-10=14
f(6)=14
Answer:
T = 7M/N
Step-by-step explanation:
Cross multiply
NT = 7M
Divide by N
NT/N = 7M/N
T = 7M/N
Answer:
Translate 7 units up and then translate 11 units to the left.
Step-by-step explanation:
We have the triangle PQR having co-ordinates (10,6), (6,2) and (4,-1).
It is required to translate ΔPQR so that the resulting image is completely inside the 2nd quadrant.
So, for that we will apply the following sequence of translations:
1. Translate 7 units up.
This will give us the figure in the 1st quadrant having co-ordinates (10,1), (6,9) and (4,6).
2. Translate 11 units to the left
We will get the final triangle P'Q'R' with the co-ordinates P'(-1,1), Q'(-5,9) and R'(-7,6) as shown below.
