The minimum number of rolls that can be bought is 4.
The first step is to determine the perimeter of the ceiling and the length of its hypotenuse.
Perimeter of the ceiling = perimeter of a square = 4 x length = 4 x 16 = 64 ft
The hypotenuse is the distance from one corner of the ceiling to the other corner of the ceiling. The hypotenuse would be determined using the Pythagoras theorem.
The Pythagoras theorem: a² + b² = c²
where a = length
b = base
c = hypotenuse
16² + 16²
= 256 + 256
= 512 feet
c = √512 = 22.6 feet
Total length = 22.6 feet + 64 feet = 86.63 feet
Minimum number of rolls = 86.63 / 25 = 3.46 = 4

Answer:
2x+5=x+12
y-4=x+5
Step-by-step explanation:
first solve for x, then put the variable of x into the secon equation and solve for y
For the triangle use 14 for the height and 9 for the base. use the formula 1/2bh and multiple it by two.
for the circle do 3.14 times 9 squared and divided it by two. formula 3.14r^2.
the answer should be 317.34
hope this helps.
A gardener purchases a ceramic planter, in the shape of a hemisphere, for a small batch of leftover annuals. The volume of a hemisphere is modeled by the function V = 2/3πr 3
<span>A. Write a model for the radius as a function of the volume. </span>
<span>B. The label on the planter says that it holds approximately 134 cubic inches of potting soil. What is the radius of the planter, rounded to the nearest inch? Use 3.14 for π </span>
<span>r = ∛[(3/2)V) / π] </span>
<span>134 = (2/3) (3/14) r^3 </span>
<span>r = ∛[(3/2) (134) / 3.14] ≈ 4.00 inches </span>
