Answer:
H=2  r=1
Step-by-step explanation:
P= 2h+4r + πr = π+8
h= π+8- πr -4r/2

Answer:
The original price of the laptop is 840
Step-by-step explanation:
Here, we want to calculate the original price of a laptop, given the amount that was paid off and the discount percentage enjoyed.
Firstly, let’s add back the 50 taken off. That makes a total of 50 + 664 = 714
Now, we remember he was also given 15% off. Let the price paid be x;
The 15% of x is equal the difference between x and the 714
Thus;
15/100 * x = x - 714
15x/100 = (x-714)
15x = 100(x-714)
15x = 100x -71400
100x-15x = 71400
85x = 71400
x = 71400/85
x = 840
 
        
             
        
        
        
Answer: The answer would be a line that is not as steep and a reflection in the line y = x.
If the a value in the equation is greater than 1, we will have a line that is steeper than the line y = x.  
Now, we we take the inverse of the line, it will have a slope that is lower than y = x.
The graphs will be reflected in the line y = x.
Try graphing y = 3x and 3y = x.
        
             
        
        
        
well, you saw it on the previous exercise, 8.25 x 10⁻⁶, it <u>looks</u> like 8.25 is some value between 1 and 10, but is not really, the 10⁻⁶ is disguising that is really much smaller than that, in fact much smaller than even 1.
 
        
             
        
        
        
Answer:
a) 0.4567
b) 6 hours                       
Step-by-step explanation:
We are given the following information the question:
The battery life follows a normal distribution with

Formula:

a) We have to find probability such that battery life exceeds 10 hours, that is,
P(X>10)

b) We have to find battery life such that 

Here, we calculated the value of z from the normal distribution table.
So, after approximately 6 hours one should plan to recharge the phone.
