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.

Answer:
y =-4
x = 1
Step-by-step explanation:
Add the two equations
4x - y + 6x + y = 8 + 2 add like terms
10x = 10 divide both sides by 10
x = 1 now to calculate y replace x in first equation by 1
4x - y = 8
4 - y = 8 subtract 4 from both sides
-y = 4 and y = -4

Answers
Answer:
A and C are the correct answers.
Step-by-step explanation:
Monomials without a variable go after the monomials with a variable. Variables with high exponents go first. A and C both show those.
In choice A, since 3z has a variable, it goes before 1. In choice C, since -5p^5 has the highest exponent it does go first. Then 2p^2, since it has the second highest exponent. Then -3p follows, with the lower exponent. Then 1 goes last because it has no variable and has the lowest exponent.Pleaseee helppp ASAP

How many solutions does this equation have?
8z − 5 = 8z
Answers
Answer:
Zero
Step-by-step explanation:
Solve the equation by subtracting 8z from both sides:
8z − 5 = 8z
-5 = 0
-5 [tex]\neq[/tex] 0
This is a false statement, because -5 is not equal to zero.
This means that there are no solutions to the equation.
So, the equation has zero solutions
Because both sides of the equation have the same variable ( they both have 8x) this equation does not have any solutions.

Based on the table, how much more money would a person with a bachelor's degree earn than a person with an associate's degree over a 30 year career?
A) $16,000
B) $480,000
C) $1,095,000
D) $1,575,000
Answers
Answer:
B) $480,000
Step-by-step explanation:
Annual salary of a person with associate's degree
= $36,500
Over a 30 year career the person would earn;
= 30 × 36500
= $10,95,000
Now, annual salary of a person with bachelor's degree = $52,500
Over a course of 30 years he would earn;
= 30 × 52500
= $15,75,000
Difference = $15,75,000 - $10,95,000 = $480,000
So the person with bachelor's degree would earn $480,000 more than a person with associate's degree.

The total surface area of the block is 32.6 square inches.
Given that, Jake has a block shaped like the prism shown in a set of toys.
What the surface area of a prism?To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.
The total surface area of a prism = (2 × Base Area) + (Base perimeter × L).
Here, area = 2 ×1/2×2×2.3 +(2+2.5+2.5)×4
= 4.6+28
= 32.6 square inches
Therefore, the total surface area of the block is 32.6 square inches.
