Answer:
(a) T = 16√x
Step-by-step explanation:
T is directly proportional to √x, so we can say,
T=k√x (where k is a constant)
now, according to the question,
400=k×√625
400=k×25
k=16
so, putting the value of k in the equation, T=16√x

The answer is that Lara would need 9 pages to store all her photos.
Step-by-step explanation:
You would need to first divided 43 divided by 5 to get 8.6.

Solution :
Let y = amount of caffeine at a given time in body.
n = number of hours
So 

ln Y = -0.01 n + C
At n = 0, Y = 130 mg
ln 130 = -0.01 x 0 + C
C = ln 130


When Y = 65



n = 69.315 hours
At n = 24 hours

Y = 102.26 mg
Answer: 6 1/5 miles
Step-by-step explanation:
Here's the complete question:
On Tuesday, Stacy rode her bicycle 1 3/4 miles from her house to the supermarket. She walked 1/4 of a mile while at the supermarket. She rode her bicycle a different way home that was 2 1/5 miles long. How many miles did Stacy ride her bicycle on Tuesday.
The number of miles that Stacy ride her bicycle on Tuesday will be the addition of her distance from her house to the supermarket and back to her house from the supermarket. This will be:
= Distance to supermarket = 1¾ + ¼ = 2 miles
Distance from supermarket = 2 + 2 1/5 = 4 1/5 miles
Total distance = 2 + 4 1/5 = 6 1/5 miles
