The ceiling of Katie’s living room is a square that is 15 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 20 ft of crepe paper. What is the minimum number of rolls she should buy? Show your work.
Answers
Answer:
6 rolls because the total perimeter is 102 ft and five rolls is only 100 feet. So she needs 6 rolls.
Step-by-step explanation:
to find perimeter, add up all the side lengths.
so 15*4 (it's easier than 15+15+15...)
60 ft.
now we have to use Pythagorean's Theorum to find corner to corner.
so [tex]a^2+b^2=c^2[/tex]
we have a and b
[tex]15^2+15^2=c^2[/tex]
do the math...
225+225= 450
square root of 450=
21.213
double that because it's used twice (corner to corner and corner to corner)
42.426
now add it all up
42.426 + 60 = 102.426
we can round
102
20*5 = 100
so she needs 6
MY ORIGINAL ERROR WAS 5, BUT 5 TIMES 20 IS ONLY 80, SO THEREFORE 6 IS REQUIRED SO THERE IS ENOUGH TO COVER 102.
Answer:
Katie needs 6 crepe rolls.
Step-by-step explanation:
Hello!
Katie originally needed ~5.1 crepe rolls, but since its a question on how many rolls she should by, she should get 6.
There are a couple of steps in order to solve this.

a₂ = 9 = 3² = (2 + 1)²
a₃ = 16 = 4² = (3 + 1)²
a₄ = 25 = 5² = (4 + 1)²

3c+6=18 how do you work this problem?
Answers
Answer:
c = 4
Step-by-step explanation:
Simplifying
3c + 6 = 18
Reorder the terms:
6 + 3c = 18
Solving
6 + 3c = 18
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 3c = 18 + -6
Combine like terms: 6 + -6 = 0
0 + 3c = 18 + -6
3c = 18 + -6
Combine like terms: 18 + -6 = 12
3c = 12
Divide each side by '3'.
c = 4
Simplifying
c = 4
Answer:
Step-by-step explanation:
subtract six from both sides
3c+6-6=18-6
simplify
3c=12
divide both sides by 3
3c/3 =12/3
c=4

Answers
Answer:
106°
Step-by-step explanation:
By exterior angle theorem:
[tex]m \angle \: 1 = 62 \degree + 44 \degree \\ \\ m \angle \: 1 = 106 \degree[/tex]
Step-by-step explanation:
Let the unknown angle in the triangle be x.
x + 44 + 62 = 180(sum of angles in a triangle)
x + 106 = 180
x = 180 - 106
x = 74
Angle 1 + x = 180 (Sum of angles on the same straight line)
angle 1 + 74 = 180
Angle 1 = 180 - 74
= 106

Answers
9514 1404 393
Answer:
a. 21
Step-by-step explanation:
The external part of the hypotenuse of the right triangle is shown. The full length of the hypotenuse is 9+20 = 29. The Pythagorean theorem can be used to find x.
x^2 +20^2 = 29^2
x^2 = 841 -400
x = √441
x = 21
__
Alternate solution
The diameter of the circle is 2·20 = 40 units, so the product of distances from the external vertex to the opposite sides of the circle along the secant is (9)(40+9). The product of the distances along the tangent is x·x. These two products are equal, so ...
x^2 = 9(49)
x = (√9)(√49) = 3·7
x = 21
