Answer:
Distance covered by Eli is 
miles.
Step-by-step explanation:
Eli biked the distance from his home initially = 
miles
Then he remembered that he had left a book at home.
He came back home and traveled the distance = miles
Then he reached the library by traveling the distance = 
miles
Total distance covered by him = 
= 
= 5 + 
= 
= 
= miles
Therefore, distance covered by Eli is miles.
Answer:
y=4x-2
Step-by-step explanation:
the equation of a straight line is given by
y=mx+c
where m is gradient slope and c is y - intercept
y=4x-2
Answer:
C
Step-by-step explanation:
put it in slope intercept form
y=2x-3
2= slope
Answer: the height of the water after the sphere is placed in
it is 33.33 cm
Step-by-step explanation:
The cylinder is called a right circular cylinder because its height make a right angle with its base. The formula for determining the volume of the cylinder is expressed as
Volume = πr^2h
Where
π is a constant whose value is 3.14
r represents the radius of the cylinder.
h represents the height of the cylinder.
From the information given,
r = 10 cm
h = height of water in the cylinder = 20 cm
Volume of water in the cylinder before the sphere was placed in it would be
V = 3.14 × 10^2 × 20 = 6280 cm^3
The formula for determining the volume of the sphere is expressed as
Volume = 4/3 πr^3
V = 4/3 × 3.14 × 10^3 = 4186.67cm^3
Total volume of the sphere and the cylinder = 6280 + 4186.67 = 10466.67 cm^2
To determine the new height of the water,
10466.67 = 3.14 × 10^2× h
h = 10466.67/314 = 33.33 cm
