Answer:
530.66
Step-by-step explanation:
to find the area you need to do pi times the radius square and to find the radius squared you just times it by its self so 13 times 13 which is 169 and pi is 3.14
so now you just do 3.14x169=530.66

An hour before showtime only 105 people have a ride for a concert according to sales 95% of the people have yet to arrive how many tickets were sold for the concert explain
Given:
An hour before showtime only 105 people have arrived for a concert.
According to sales 95% of the people have yet to arrive.
To find:
The total number of tickets sold.
Solution:
Let x be the total number of tickets sold.
According to sales 95% of the people have yet to arrive.
[tex]100\%-95\%=5\%[/tex]
It means, only 5% people have arrived.
[tex]\dfrac{5}{100}x=105[/tex]
[tex]\dfrac{1}{20}x=105[/tex]
[tex]x=105\times 20[/tex]
[tex]x=2100[/tex]
Therefore, the total 2100 tickets were sold.

Help fast It's do today
Answer:
D. 33 - 42
Step-by-step explanation:
Kathy distributes jelly beans among her friends.
Number of jelly beans received by Kelly after distribution of Jellies by Kathy = 33
Also, Alia gets 42 fewer jelly beans than Kelly
Now, we need to find the number of jelly beans received by Alia
So, Number of jelly beans received by Alia = No. of jelly beans received by Kelly - 33
⇒ Number of jelly beans received by Alia = 42 - 33
Therefore, The correct answer is D. 33 - 42

The answer is D. i took the test and got it right brainlist plssssssssssss
Step-by-step explanation:
The boundary line of a linear inequality passes through the points (3,0) and (0,6). The points (3,0) and (2,6) are not solutions of the inequality. Write the linear inequality
Answer:
[tex]y<-2x+6[/tex]
Step-by-step explanation:
The boundary line of a linear inequality passes through the points (3, 0) and (0, 6).
The points (3, 0) and (2, 6) are not solutions of the inequality.
We want to find the equation of the linear inequality.
First, we will simply find the line that crosses the points (3, 0) and (0, 6).
We can determine the slope to be:
[tex]\displaystyle \frac{6-0}{0-3}=\frac{6}{-3}=-2[/tex]
Notice that (0, 6) is the y-intercept.
Then by the slope-intercept form:
[tex]y=mx+b[/tex]
Our equation will be:
[tex]y=-2x+6[/tex]
Now, we will need to determine our inequality sign.
First, (3,0) is on the boundary line yet it is not a solution. Therefore, our line is dotted. That is: we do not have the "or equal to" statement.
So, our inequality signs can only be either < or >.
We are given that (2, 6) is not a solution.
So, we can test for the sign. Substitute 2 for x and 6 for y:
[tex]\displaystyle 6\text{ }?\text{ }-2(2)+6[/tex]
Evaluate:
[tex]\displaystyle 6\text{ } ?\text{ } 2[/tex]
Since 6 is not a solution, the above statement needs to be false.
It will be false is the sign is <, since 2 is not greater than 6.
Therefore, our sign is <.
And our inequality is:
[tex]y<-2x+6[/tex]

Two angles are complementary, can they also be supplementary? Explain.
Answer:
Yes
Step-by-step explanation:
They can because the sum of two Angles is 180, and if they are both 90, they add up to 180, making them congruent. Hope this helps
Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees.
Saying this you should probably infer that if 2 Angles are complementary, then they are 90°.
Meaning you would need 2 pairs of complementary angles to have a supplementary angle (180°).
erin has 40,000 in a savings account that earns 15% interest per year. the interest is not compounded. how much will she have in 3 months?
Answer:
$41500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 15%/100 = 0.15 per year,
putting time into years for simplicity,
3 months ÷ 12 months/year = 0.25 years,
then, solving our equation
I = 40000 × 0.15 × 0.25 = 1500
I = $ 1,500.00
The simple interest accumulated
on a principal of $ 40,000.00
at a rate of 15% per year
for 0.25 years (3 months) is $ 1,500.00.

A square has legs of 11, what is the measure of its hypotenuse
A.) 9.4 or B.)15.6
15.6 is the measure of the hypotenuse of the square.
What is a square?A square is a two-dimensional closed shape with 4 equal sides and 4 vertices.
Given that one side of the square is 11.
The diagonal is the hypotenuse of the square.
Since square have equal sides, the hypotenuse can be obtained using Pythagorean theorem.
i.e. 11² + 11² = (hypotenuse)²
i,.e. (hypotenuse)² = 121+121 =242
Therefore, hypotenuse = √242 = 15.6
Hence, the measure of the hypotenuse of the square is 15.6

the 100th term of the sequence with the term -1-4n
Given:
The terms of a sequence are given by
[tex]a_n=-1-4n[/tex]
To find:
The 100th term of the sequence.
Solution:
We have,
[tex]a_n=-1-4n[/tex]
Putting n=100, we get
[tex]a_{100}=-1-4(100)[/tex]
[tex]a_{100}=-1-400[/tex]
[tex]a_{100}=-401[/tex]
Therefore, the 100th term of the given sequence is -401.

Given:
Point V is located at (-5,3) on the coordinate plane.
It is reflected over the y-axis to create point V'.
Point V' is then reflected over the x-axis to create point V''.

The simplified version of this x-2z
Step-by-step explanation:
You need to start by combining like terms. You can start with the terms that have the variable x in them. By combining those terms, the equation becomes x+3y-z-3y-z.
From here, you can combine the terms 3y and -3y, which bring the equation to x-z-z.
From here, combine the terms with the variable z. This would bring the equation down too x-2z, your final answer.
