Answer:
56.5
Step-by-step explanation:
To find the perimeter of circle (circumference), we multiply Pi and our radius (half the length across the circle) and then multiply that by 2. perimeter = 2 · π · r
Multiply 18x2 to get 36. Multiply that by pi to get 56.54866776 ( just round to nearest tenth for simplicty ;) ) Therefore, our answer is 56.5

Ms. O'Brien makes her own cleaning solution to clean her floors! (yet, she can't clean her measuring cups?) She mixes 8 cups of water with 2 cups of vinegar. If she wants to make a 1 gallon mixture of her cleaning solution, how much water and how much vinegar should she add? (**There are 16 cups in a gallon)
Answer:
To make a gallons,
Ms. O'Brien needs
12 8/10 cups of water or 12.8 cups of water
3 1/5 cups of water or 3.2 cups of vinegar
Step-by-step explanation:
Ms. O'Brien makes her own cleaning solution to clean her floors! (yet, she can't clean her measuring cups?)
She mixes 8 cups of water with 2 cups of vinegar.
Hence: The total number of cups for the cleaning mixture = 8 cups of water + 2 cups of vinegar = 10 cups
If she wants to make a 1 gallon mixture of her cleaning solution, how much water and how much vinegar should she add?
Note that: There are 16 cups in a gallon
Hence:
For number of cups of water:
10 cups of cleaning mixture = 8 cups of water
16 cups of cleaning mixture = x
Cross Multiply
10x = 16 × 8
x = 16 × 8/10
x = 12 8/10 cups of water or 12.8 cups of water
For the number of cups of vinegar
10 cups of cleaning mixture = 2 cups of water
16 cups of cleaning mixture = x
Cross Multiply
10x = 16 × 2
x = 16 × 2/10
x = 3 1/5 cups of water or 3.2 cups of vinegar
Therefore, to make a gallon
Ms. O'Brien needs
12 8/10 cups of water or 12.8 cups of water
3 1/5 cups of water or 3.2 cups of vinegar

Answer:
51
Step-by-step explanation:
The range is the largest number minus the smallest number
The largest number is 54 and the smallest number is 3
54-3 = 51
A ball is launched out of a cannon that is 24 feet off the ground. The height of the ball after "t" seconds is represented by
h(t) = -16t² + 20x + 24
How many seconds will it take for the to reach the ground?
Given:
The height of ball is represented by the below function:
[tex]h(t)=-16t^2+20t+24[/tex]
To find:
The number of seconds it will take to reach the ground.
Solution:
We have,
[tex]h(t)=-16t^2+20t+24[/tex]
At ground level, the height of ball is 0, i.e., [tex]h(t)=0[/tex].
[tex]-16t^2+20t+24=0[/tex]
Taking out greatest common factor.
[tex]-4(4t^2-5t-6)=0[/tex]
[tex]4t^2-5t-6=0[/tex]
Splitting the middle term, we get
[tex]4t^2-8t+3t-6=0[/tex]
[tex]4t(t-2)+3(t-2)=0[/tex]
[tex](t-2)(4t+3)=0[/tex]
Using zero product property, we get
[tex](t-2)=0[/tex] and [tex](4t+3)=0[/tex]
[tex]t=2[/tex] and [tex]t=-\dfrac{3}{4}[/tex]
Time cannot be negative, so [tex]t=2[/tex].
Therefore, the ball will reach the ground after 2 seconds.

This is the question I am gonna write it here pls help Yum-Yum restaurant has just increased the wages they pay their employees. To help afford this,Yum-Yum-Yum must mark up their meals by 12%. If the meal cost 7.99, how much will as meal cost after the markup
Answer:
8.95
Step-by-step explanation:
Convert 12% into a decimal by dividing 12 by 100 to get 0.12. To find 12% of 7.99, multiply it by 0.12. However, since we want to know the total cost of the meal after the markup, an eaiser way is to multiply 7.99 x 1.12 (the 1 represents the original price of meal, since we are adding on to it). This is the more effective way to solve this, but another way would just be to take the result of 7.99 x 0.12 and add it to 7.99.
Note that the actual answer is 8.9488, but I rounded to the nearest hundreth.
A township supervisor hopes to improve the current recycling program by having residents separate their recycled
materials by type. For example, glass and plastic materials would be placed into separate recycling containers. To
measure community support for a change to the recycling program, the supervisor visits a busy shopping area and
asks randomly selected residents to respond to the following question: "Do you agree that responsible citizens
would separate their recycled items by type of material?” What type of bias could be present in the survey results
and what is a likely direction of the bias in estimating community support for the change to the recycling program?
This is question wording bias. The survey overestimates community support for change to the recycling program.
This is question wording bias. The survey underestimates community support for change to the recycling
program
This is voluntary response bias. The survey overestimates community support for change to the recycling

This is voluntary response bias. The survey underestimates community support for change to the recycling
program
Answer:
B
Step-by-step explanation:
It is necessary and the strategic way to collect the waste materials and separate them by material type before recycling. Hence, this is voluntary response bias. The survey overestimates community support for change to the recycling program.
What is recycling?Recycling is the process regenerating new products from the decomposed materials such as broken plastics, fuel from biowastes, glasses from broken glass parts etc.
Recycling technology is a nature genuine strategy and it helps to reduce the accumulation of wastes on earth surface. Not all people are aware of the significance of this method.
Therefore, the bias possible to be occur for the question is from voluntary response and the survey underestimates community support for change to the recycling program.

Answer: 1056 in.³
Step-by-step explanation: The formula for finding the volume of a rectangular prism is V = L × W × H. (Volume equals Length times width times height.) 11 × 4 × 4 = 176. To find the volume of all the rectangular prisms, you multiply the volume of one of the prisms by 6 because there are 6 prisms shown. The total volume of the shape is 1056 in³.

its about quartiles

Answer: See the attached image for the answers. I've arranged the tiles in the proper order.
minimum = 2lower quartile = 4second quartile = 8upper quartile = 19maximum = 21This is known as a five number summary.
=========================================================
Explanation:
The first thing to do is to sort the numbers from smallest to largest
You should get this set {2, 4, 7, 8, 16, 19, 21}
The middle most value is 8. So this is the median or the second quartile.
--------------
Split the data set into two lists like so
L = {2,4,7}
U = {16,19,21}
Everything in set L represents the lower set of values smaller than the median. Set U represents the upper set of values larger than the median.
Find the median of sets L and U to get 4 and 19 respectively. These represent the values of Q1 and Q3
Q1 = first quartile = lower quartile = 4
Q3 = third quartile = upper quartile = 19
--------------
As you can probably guess, the min and max are the smallest and largest values of the set. We can see that min = 2 and max = 21.

An amount of $45,000 is borrowed for 13 years at 6.75% interest, compounded annually. If the loan
paid back
Use the calculator provided and round your answer to the nearest dollar,
Answer:
$104850
Step-by-step explanation:
Given data
Principal= $45,000
Time = 13 years
Rate= 6.75%
the compound interest expression is
A= P(1+r)^t
A=45000(1+0.0675)^13
A= 45000(1.0675)^13
A= 45000*2.33
A= $104850
Hence the final amount will be $104850

Answer:
The measure of angle A is 48.4 degrees
Step-by-step explanation:
To find the measure of angle A, we are going to use the cosine rule
We have this as;
a^2 = b^2 + c^2 - 2bc Cos A
a^2 = 11^2 + 13^2 -2(11)(13) cos A
100 = 121 + 169- 286cos A
286 cos A = 290-100
286 cos A = 190
cos A = 190/286
cos A = 0.6643
A = arc cos 0.6643
A = 48.4 degrees
