A flying disc in the shape of a circle has a circumference of 8 inches. What is the radius of the flying disc.
Answers
Answer:
A.
Step-by-step explanation:
Recall that circumference is given by:
[tex]C=2\pi r[/tex]
We know that the circumference is 8π inches. Thus, we can substitute 8π for C:
[tex]8\pi =2\pi r[/tex]
To solve for r, the radius, we can divide both sides by 2π. Hence:
[tex]\displaystyle r = \frac{8\pi}{2\pi}=4[/tex]
Therefore, the radius is four inches.
Our answer is A.

A triangle has side lengths of n, n - 3, and 2(n - 2). If the perimeter of the triangle is at least 37 units, what is the value of n?
Answers
Answer:
n = 11
Step-by-step explanation:
Perimeter = sum of all the sides
n + n - 3 + 2(n-2) = 37 units
n + n - 3 + 2n - 4 = 37 {Combine like terms}
n + n + 2n - 3 - 4 = 37
4n - 7 = 37
4n= 37 + 7
4n = 44
n = 44/4
n = 11

[tex]A = \{a, c, e, g\}[/tex]
Required
Find the complement of A
The complement of A are elements in the universal set (U) but not in A.
In other words,
if [tex]A = \{a, c, e, g\}[/tex]
then A' are the elements other than a, c, e and g that are in the universal set
So

A store is hoping an advertising campaign will increase their number of customers by 30%. They currently have about 80 customers a day.
Answers
Answer:
There will be 104 customers a day, after advertising campaign
Step-by-step explanation:
Current number of customers in a day in shop = 80
After advertising campaign, the customers will increase = 30%
So, new customers will be:
We can find new customers by adding new 30% customers to the current 80 customers.
First find 30% of 80
[tex]30\% \ of \ 30\\=\frac{30}{100}*80\\=24[/tex]
Now, add 24 to current 80 customers.
Number of customers = 80+24 = 104
So, there will be 104 customers a day, after advertising campaign
Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. The angle of elevation of the tree from one position on a flat path from the tree is H=60°, and from a second position L=20 feet farther along this path it is B=50° What is the height of the tree?
Answers
Answer: 44.11 feets
Step-by-step explanation:
Using Pythagoras :
tan θ = opposite / Adjacent
Tan 60° = h / x
h = x tan 60 - - - (1)
tan 50° = h / (x + 20)
h = (x + 20) tan 50 - - - (2)
Equate (1) and (2)
x tan60 = (x + 20) tan 50
1.73205x = (x + 20) 1.19175
1.73205x = 1.19175x + 23.835
1.73205x - 1.19175x = 23.835
0.5403x = 23.835
x = 23.835 / 0.5403
x = 44.114380
Hence, height = 44.11 feets

The graph shows the distribution of the number of text messages young adults send per day. The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.
What percentage of young adults send more than 158 text messages per day?
16%
34%
68%
84%
Answers
Answer:
16%
Step-by-step explanation:
From the graph of distribution of the number of text messages
Young adults send more than 158 text messages per day is 16%
Given :
The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.
Given 158 text messages . so x is 168
Now we find out z -score
[tex]z=\frac{x-mean}{standard\; deviation }[/tex]
Replace the values and find out z
[tex]z=\frac{158-128}{30} =1[/tex]
the value of z=1
Lets use the standard deviation table that gives area on the left
the table gives the percentage of adults less than 158
z-score value for z=1 is 0.8413
Now, percentage of young adults send more than 158 text messages
Percent (more than 158)=1- P(less than 158)=[tex]1-0.8413=0.1587[/tex]
To get percentage we multiply by 100
[tex]0.1587 \cdot 100= 15.87= 16[/tex]
Young adults send more than 158 text messages per day is 16%

Step-by-step explanation:
This graph is discrete. A discrete graph has separate values, which are represented by multiple unconnected points. In continuous graphs, the values are all connected to each other. If this graph was continuous, then we would see a line rather than separate dots. The graph can also not be neither continuous nor discreet because it passes the vertical line test, meaning that it is a function.

x 100 x is the unknown variable. (the total questions on the test)
Cross multiply to get this: 64*100 = 68x
6400 = 68x (Divide by 68 on both sides)
You should get about 94.11 after dividing. You have to round as there cannot be have a question. It should be rounded to 94 questions. There are 94 questions and 64 were missed. To check your work, do 64/94. This should give you about 68% after rounding.
