Answer:
586Step-by-step explanation:
Using set notation to answer the question.
let n(U) be the total number of people surveyed = 1000
n(L) be number of people that visited London = 310
n(P) be number of people that visited Paris = 222
n(P∩L) be number of people that visited both cities = 118
n(P∪L)' be number of people that visited none of the cities = x
n(U) = n(PUL) + n(PUL)'
We willl get n(PUL) using the formula;
n(PUL) = n(P)+ n(L)-n(P∩L)
n(PUL)= 222+310-118
n(PUL)= 414
Since n(U) = n(PUL) + n(PUL)'
1000 = 414+n(PUL)'
n(PUL)' = 1000-414
n(PUL)' = 586

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first. The tax in the staty was
10%, and the tax in the second city was 5%. The total hotel tax paid for the two cities was $600. How much was the hotel charge in each oty before tax?
Answer:
The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000
Step-by-step explanation:
Let x be the hotel charge without tax in first city
We are given that The hotel charge before tax in the second city was $1500 lower than in the first.
So, Hotel charge without tax in second city =x-1500
Tax% in first city = 10%
So, tax in first city = 0.1x
Tax% in second city =5%
So, tax in second city = 0.05(x-1500)
We are given that The total hotel tax paid for the two cities was $600.
So,0.1x+0.05(x-1500)=600
0.1x+0.05x+75=600
0.15x=600-75
[tex]x=\frac{600-75}{0.15}[/tex]
x=3500
Hotel charge without tax in first city = $3500
The hotel charge before tax in the second city =x-1500=3500-1500=2000
Hence The Hotel charge without tax in first city is $3500 and The hotel charge before tax in the second city is 2000

A rectangle room measures 13 feet by 15 feet. The ceiling fan is 8 feet high. Find the total area of all 4 walls that will need to be painted.
448 ft
224 ft
560 ft
336 ft
Answer:
448 ft^2
Step-by-step explanation:
The area of the walls is the perimeter of the room multiplied by the height.
P = 2(L + W)
P = 2(13 ft + 15 ft)
P = 2(28 ft)
P = 56 ft
A = perimeter * height
A = 56 ft * 8 ft
A = 448 ft^2
Do you use the greatest common factor or the least common multiple to add to fractions? In this example what is it? 4/15+5/6
Answer:
The least common multiple, but you can use the greatest common factor, but at the end you have to simplify for it to be correct. 1 3/30
Step-by-step explanation: 4/15+5/6
Change 15 into a 30 by multiplying 2 to both sides.
Change 6 into a 30 by multiplying 5 to both sides.
so the new fractions are 8/30+25/30=33/30
The final fraction is 1 3/30.

Use the combination method to solve for y: 5x + 3y = 12 and -5x + 4y = 16
y= 4
y= 0
y= -10
y= -4
Answer:
y = 4
Step-by-step explanation:
We have,
5x + 3y = 12 ....(1)
and
-5x + 4y = 16 ....(2)
Adding equation (1) and (2),
0 + 7y = 28
or
7y = 28
Dividing both sides by 7,
y = 4
So, the value of y = 4.

Help! Giving brainliest.
Answer:
The area of rectangle A is length x breadth
= 3x5
= 15 units^2
The area of square B is side x side
= 3x3
= 9 units^2
Therefore,
The area of the rectangle is not double of the area of the square because 9x2 is not equal to 15. Steven isn't correct.
Answer:
a) Steven is incorrect.
b) Steven is incorrect, because he claims that, in other words, 15 units squared = 18 units squared. 18 > 15, so the statement that 15 = 18 is false. 15 does not equal 18.
Step-by-step explanation: Steven claims that the area of rectangle A is double the area of square B. The area of rectangle A is 15 units squared, because you get a product of 15 when you multiply the side lengths 5 and 3. The area of square B is 9 units squared, because you get a product of 9 when you multiply the side lengths 3 and 3. In other words, Steven is claiming that the area of rectangle A is not 15 units squared, but 18 units squared (this is double the area of square B, as 18 is the product of 9 and 2), and that statement is false, because we know that 18 > 15. Therefore, 18 cannot equal 15; the figure that is made from the value of double the area of square B (18 units squared) is larger than rectangle A (15 units squared) - this reinforces the fact that 18 > 15, and hence cannot be equal to 15.

1) Miguel sells a house for $275,000. His commission for the sale is $6,875. What percent commission did he earn? (Make sure to write your answer as a percent for example: 6.2%)
Answer: 2.5%
Step-by-step explanation:
Let's use the rule of 3 here.
If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.
Let's put money on one side and percentages on the other.
[tex]\frac{275000}{6875}=\frac{100}{x}[/tex]
Solve for x;
[tex]x=\frac{6875*100}{275000}[/tex]
[tex]x=2.5[/tex]
The Percent commission Miguel earn is 2.5%.
To Find the percent commission Miguel earnedGiven:
Miguel sells a house = $275,000
His commission for the sale =$6,875.
Step 1:
Let's use the rule of 3 here.
If the total price is $275,000 or 100% of the sale,
then $6,875 is X% of the total sale.
Step 2:
Let's put money on one side and percentages on the other
=275000/6875
= 100/x
Solve for x;
x = 6875×100/275000
x = 2.5
Therefore, Percent commission did Miguel earn is 2.5%.

what is the simplified form of 5 square root x^4 • 5 square root x^4
Answer: C
Step-by-step explanation:
You can write each term into a fraction.
[tex]\sqrt[5]{x^4}[/tex] becomes [tex]x^4^/^5[/tex]
When you multiply 2 terms with the same base, you add the exponents.
[tex]x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5[/tex]
[tex]x^8^/^5[/tex] is also the same as [tex]x\sqrt[5]{x^3}[/tex]
You get this because [tex]\sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}[/tex]. When you pull out 5 os x, you are left with x³ on the inside.
The graph of y= √x is transformed as shown in the graph below. Which equation represents the transformed function?
Answer:
1
Step-by-step explanation:
Firstly note that the graph is shifted up 2 units, as it starts at positive 2, when it should start at 0.
That only leaves choices 1 and 2
However, since we know its flipped, we can easily rule out number 2, as number 2 wouldn't be a real number(sqrt of negatives)
That leaves answer choice 1
The correct option is y = -[tex]\sqrt{x}[/tex] +2

* LAST QUESTION. ANSWER ASAP W DETAILS PLEASE (: * Write an equation for the circle whose graph is shown.
Answer:
B.
Step-by-step explanation:
(x-1)2+(y+2)2=4.
because the equation is shown in the graph
the equation of the circle with a center at (-1, 2) and a radius of 2 is:
(x + 1)² + (y - 2)² = 4
From graph er can see that center of circle is (-1,2) and radius is 2
The equation of a circle with its center at point (h, k) and radius r is given by:
(x - h)² + (y - k)² = r²
In this case, the center of the circle is (-1, 2), and the radius is 2. Plugging these values into the equation, we have:
(x - (-1))² + (y - 2)² = 2²
Simplifying further:
(x + 1)² + (y - 2)² = 4
Expanding the square terms:
x² + 2x + 1 + y² - 4y + 4 = 4
Combining like terms:
x² + y² + 2x - 4y + 1 + 4 - 4 = 0
Simplifying:
x² + y² + 2x - 4y + 1 = 0
Therefore, the equation of the circle with a center at (-1, 2) and a radius of 2 is:
(x + 1)² + (y - 2)² = 4
