Answer:
It is approximately 25. The answer I got is 24.96 so I rounded it off to 25.
Step-by-step explanation:
Answer:
Curved surface area of sphere = 2πr × 2r=4πr^2;
The new diameter is 120/100 from the old diameter;
2R = (120/100)x(2r);
So, R = 1.2 x r;
Curved surface area of new sphere = 4πR^2 = 4π(1.2xr)^2= 4πr^2x1.44= curved surface of old sphere x (144%);
Finnaly, the increase is 44%.

Answer:
The price to pay is $16.22
Step-by-step explanation:
From the question, the regular price is $24.95
now, there is a discount
So the price to pay is the regular minus the discount
Mathematically, we have this as:
24.95 - 35% of 24.95
= 24.95 - 0.35(24.95)
= $16.2175
This is approximately $16.22
You can easily tell if Keisha will finish reading the book by this equation:
y = 325 - 25x
where y is the number of pages left, and x is the number of days. A point slope for has a standard form of y - y1 = m(x - x1). Thus, we arrange it in this manner:
y = 25(13 - x)
Then, substitute x = 10:
y = 25(13 - 10)
y = 75
So, Keisha will not be able to finish the book in 10 days. There are still 75 pages left to read.
