Answer:
area will be four times the first area
Step-by-step explanation:
the diameter of the first sphere=d
therefore radius=d/2
=r
the diameter of the second sphere becomes 2d
therefore the radius of second sphere=2r
area of a sphere=4×pi×r^2
the ratio of the two spheres=(4pi(2r)^2)/(4pir^2)
=(4pi4r^2)/4pir^2
cancelling 4pir^2, you get 4:1
therefore the area of the second sphere is 4 times the first one
Answer:
y = 4x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = 
= 4
The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3
y = 4x - 3 ← equation of line
Move b to one side
=4b=3x
Therefore b= 3/4
In order to triple it's weight, the kitten needs to be 300 grams.
So an additional 200 pounds.
200 / 8 grams per day = 25.
25 days.
Answer:
$232
Step-by-step explanation:
1/14 of 280 is $20 and 1/10 of 280 is $28
232 - (20+28) = 232
