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.

The solution to 5 - 3x > 35 is either x > -10 or -10 > x. Which soultion is correct? Explain how you know.
Answer:
x < - 10
Step-by-step explanation:
5 - 3x > 35
-3x > 35 - 5
-3x > 30
Divide both sides by 3
-x > 10
Divide both sides by - 1
x < - 10
The inequality sign will change due to the negative sign.

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.

24 = x
Step-by-step explanation:
You use Pythagorean theorem. Since the normal equation is [tex]a^{2} + b^{2} =c^{2}[/tex], you already have the [tex]c^{2}[/tex] and another side which can be [tex]a^{2}[/tex] or [tex]b^{2}[/tex].
Because you have the hypotenuse and a side , your equation looks like this now: [tex]7^{2} +b^{2} = 25^{2}[/tex]
and when you solve for be you just subtract [tex]25^{2} -7^{2}[/tex] to get 24.

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 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]

It shows that A'B'C' smaller than ABC
Answer:
The correct statement is D
Step-by-step explanation:
Triangle A'B'C' is a diluted version of triangle ABC, so it would be smaller than triangle ABC since its x-value and y-value are being multiplied by a number less than 1.

Which expression is equivalent to 2(8n)^4
Answer:
2* 8n* 8n* 8n*8n
Step-by-step explanation:
Break it down 2(8n)^4 because 4 is the exponent you will multiply 8n four times so it will be 8n*8n*8n*8n so add the 2 to it and it will be 2*8n*8n*8n*8n. Hope this help :)
The expression 2(8n)⁴ is equivalent to 2¹³n⁴ or 8192n⁴ after simplifying.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have:
[tex]\rm = 2(8n)^4[/tex]
[tex]\rm 2\times 8^4\times n^4\\\\\rm 2\times (2^3)^4\times n^4\\\\\rm 2\times 2^1^2\times n^4\\\\\rm 2^1^3\times n^4\\\\\\\rm 2^1^3 n^4\\\\or\\\\8192n^4[/tex]
Thus, the expression 2(8n)⁴ is equivalent to 2¹³n⁴ or 8192n⁴ after simplifying.

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°).

In the figure below, Ken's company has placed sprinkler heads at the center of the two small semicircles. The radius
Of the sprinklers is 5ft If the area in the larger semicircular area is the shape of the entire lawn, how much of the lawn will not be watered?
Answer:
The answer is below
Step-by-step explanation:
The sprinklers have a radius of 5 ft each. Since the larger semicircle (entire lawn) has a diameter that is formed from the 2 semicircles, therefore the radius of the larger semicircle is 10 ft.
Area that wont be watered can be gotten by subtracting the area of the two smaller circles from the area of larger semicircle.
Area that wont be watered = 1/2(π * 10²) - 2[1/2(π * 5²)] = 50π - 25π = 25π ft²
5x+3y-z-4x-3y-z help please
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.
