Answer:
4 bananas
Step-by-step explanation:
She uses 4 bananas because if 2 are needed to prepare 1/3 pints for 2 then 2/3 u need 4
Answer:
f^-1(x) = ( x + 6 )/4
Step-by-step explanation:
f(x) is the same as...y = 4x + 6....and then try to make x the subject of formula
y + 6 = 4x
x = (y + 6)/4....then when writing f^-1(x)...replace y with x
f^-1(x) = ( x + 6 )/4
We need the circumference and area of the circle equations:
c = 2*pi*r
a = pi*r^2
lets find the radius from the first equation:
r = c/2*pi
r = 157/(2*3.14)
r = 24.99 ft
now lets calculate the area:
a = pi*r^2
a = 3.14*(24.99)^2
a = 1960.93 ft^2
Now we need to divide the total area by the rate at which Chris paints, and that gives us the time needed:
time = <span>1960.93/400
time = 4.9 hours
that would be 5 hours rounded to the nearest hour</span>
Answer:
80 units if the length is equal to x (it is unspecified)
Step-by-step explanation:
Assuming that the length is equal to x, then we know that the length is 10 units long because x = 10.
Since the width is 3 times longer than the length, we can also find that the width is 30 units long because 3 x 10 = 30.
Now, we can use the perimeter formula to find the perimeter of the rectangle.
The perimeter formula is P = 2 ( L + W ), with L being length and W being width.
Let's just substitute the numbers to find perimeter.
P = 2 ( 10 + 30 )
P = 2 ( 40 )
P = 80
So, the perimeter is 80 units.
