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.
Answer: 6
Step-by-step explanation:
The length of all sides of the square ceiling is 15 ft
Perimeter of the ceiling = 4 * length of each side = 15 * 4 = 60 ft
Distance from one corner to another corner i.e. BD and AC (in the figure below) forms the diagonals of the square ceiling
We know that,
Diagonal of a square = √(2) * a , where a is the length of the side of the square.
Therefore,
BD = AC = 15 √(2)
Thus,
Total crepe paper required = Perimeter of the ceiling + BD + AC = 60 + 15 √(2) + 12 √(2) = 102.43 ft
Crepe paper in each roll = 20 ft
Therefore,
Number of rolls required = 102.43 / 20 = 5.1215
Therefore, the minimum number of rolls she should buy is 6

An angle measures 62.4° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
If an angle measures x degrees, the measure of its supplement is (180-x) degrees.
This means that x-62.4 = 180-x, meaning that x=121.2.
So, the angles are 121.2 and 58.8 degrees.

[tex]~~~~\left(\sqrt{5} \right)^2= \left(\sqrt{2} \right)^2+\left(\sqrt{3} \right)^2\\\\\implies 5=2+3\\\\\implies 5=5[/tex]
Answer:
A
Step-by-step explanation:
using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = [tex]\sqrt{5}[/tex] , and ([tex]\sqrt{5}[/tex] )² = 5
([tex]\sqrt{2}[/tex] )² + ([tex]\sqrt{3}[/tex] )² = 2 + 3 = 5
Thus the 3 sides form a triangle
a circular clock face has a diameter of 7 inches how many inches does the tip of the minute hand travel in a day
Answer:
14π inches
Step-by-step explanation:
Diameter of the clock = 7 × π = 7π
one day = 24 hours which means
2 clockwise turns around the clock
sooo 7π × 2 = 14π
Answer:
527.52 in
Step-by-step explanation:
To answer this question you have to find the circumference of the circle.
You have to use the formula below to find the circumference.
C = π d
Here,
d ⇒ diameter ⇒ 7 in
Let us solve it now.
C = π × d
C = 3.14 × 7
C = 21.98 in
So, the tip of the minute hand is traveling 21.98 in an hour.But they're asked for the distance traveled by the tip of the minute in a day.So, to find that we have to multiply the answer by 24 hours.Let us find it now.
Distance traveled in a day = 21.98 × 24
= 527.52 in
45% of the children in a school have a dog, 30% have a cat, and 18% have a dog and a cat. What percent of those who have a dog also have a cat
The percentage of the children that have dog or cat is = 57%
Calculation of percentage of childrenThe percentage of children that have a dog = 45%
The percentage of children that have a cat = 30%
The percentage of children that have dog and cat= 18%
Therefore the percentage of children that have dog or cat = (45 + 30) - 18
= 75 - 18
= 57%
Therefore, the percentage of the children that have dog or cat is = 57%

Answer:
39.9
Step-by-step explanation:
Pls give brainlest if correct.
*Answer*:39.9
Reasoning:Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274: Rounding to the nearest hundred is 800 Rounding to the nearest ten is 840 Rounding to the nearest one is 838 Rounding to the nearest tenth is 838.3 Rounding to the nearest hundredth is 838.27
**Helping to solve**:When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same: Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be. Look to the next smallest place value, the digit to the right of the place value you're rounding to.
Therefore, the answer is C. 39.9

Answer: Its not possible.
Step-by-step explanation:There aer two vairables. Whats the value of N
Hey there!
n = 4/5(m + 7)
n = 4/5(1m + 7)
n = 4/5(1m) + 4/5(7)
n = 4/5m + 28/5
n = 4/5m + 5.6
Thus, your answer is probably:
n = 4/5m + 5.6 or n = 4/5m + 28/5

Demarcus has to wrap a gift for his friend's birthday party. the gift is in a rectangular box with the dimensions shown below. he's trying to figure out how much gift wrap he needs to cover the entire box. should he calculate the total surface area or the lateral surface area? pick the right measurement and then calculate it for him.
Amount of gift wrap to cover the entire box = total surface area of rectangular box = 1,048 in.².
What is the Total Surface Area of a Rectangular Box?The total surface area of a rectangular box is the area of all the faces of the box = 2(wl + hl + hw).
Therefore, to find the material that will cover the whole rectangular box, Demarcus should find its total surface area, given the following dimensions:
l = 20 in.w = 8 in.h = 13 in.Plug in the values into TSA = 2(wl + hl + hw):
Total surface area of rectangular box = 2(8×20 + 13×20 + 13×8) = 1,048 in.²

Answer:
11.80
Step-by-step explanation:
The $11.80 will be her July finance charge option (c) is correct.
It is given that Elizabeth’s credit card computes her finance charges using the previous balance method and a 30-day billing cycle.
It is required to find the July finance charge.
What is APR?It is defined as the annual percentage rate that represents the yearly interest rate on the borrowing.
We have a principal amount = $969.26
APR = 14.61 %
Per month percent rate = [tex]\frac{14.61}{12}[/tex] ⇒ 1.2175 %
We can calculate the finance charge from the given formula:
Finance charge = Principal value×rate×Time
= 969.29×1.2175%×1
[tex]= 969.29\times\frac{1.2175}{100}\times1[/tex]
= $11.80
Thus, the $11.80 will be her July finance charge.

median is 16 ducky quack
Answer:
16
Step-by-step explanation:
Median, also known as the "middle" value in a data set. To be able to find the median, your data needs to be in numerical order.
Quiz scores:
9, 13, 20, 15, 18, 17
Arrange in numerical order:
9, 13, 15, 17, 18, 20
Find the "middle" value:
9, 13, 15, 17, 18, 20
When there are two middle values, you add them up and divide it by 2.
15 + 17 = 32
32/2 = 16
Therefore, the median, "middle" value of this student's quizzes is 16.
