Answer: Si fuera de los que solo fuman sería del 43,5% si solo de los que lo beben sería del 20,5% si fueran los dos sería del 59%.
Step-by-step explanation:
The percentage of the population smokes or drinks is 52%.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
We are given that;
The drink is half, third and quarter of the percentage
The sum of these percentages must be 100%, so we can write an equation:
x + (1/2)x + (1/3)x + (1/4)x = 100
To solve for x, we need to simplify and isolate x. We can do this by multiplying both sides by 12, the least common multiple of 2, 3, and 4:
12x + 6x + 4x + 3x = 1200
25x = 1200
x = 1200/25
x = 48
This means that 48% of the population neither smokes nor drinks. Therefore, the percentage of the population that smokes or drinks is:
(1/2)x + (1/3)x + (1/4)x
= (1/2)(48) + (1/3)(48) + (1/4)(48)
= 24 + 16 + 12
= 52
Therefore, the percentage answer will be 52%.

Write the equation
equation in standard form
X^2-1/X+1=2
Answer:
We start with the equation:
(x^2 - 1)/(x + 1) = 2
We want to rewrite this in standard form.
We can multiply both sides by (x + 1) to get:
((x^2 - 1)/(x + 1))*(x + 1) = 2*(x + 1)
x^2 - 1 = 2*(x + 1) = 2*x + 2
Now we can move all the terms to one side to get:
x^2 - 1 - 2 - 2*x = 0
x^2 - 2*x - 3 = 0
And this is a standard quadratic equation, that we can solve by using the Bhaskara's formula, this will give us the solutions:
[tex]x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4*1*(-3)} }{2*1} = \frac{2 \pm 4}{2}[/tex]
Then the two solutions are:
x = (2 + 4)/2 = 3
x = (2 - 4)/2 = -1

Ian paints /8 of a fence. Anna paints 3/4 of another fence. Draw a number line to show that Ian and Anna have painted the same amount of each fence.
Answer:
See attachment for number line
Step-by-step explanation:
Given
[tex]Ian = \frac{6}{8}[/tex]
[tex]Anna = \frac{3}{4}[/tex]
Required
Number line to represent both amounts
The interval on the number line is 16.
So, we need to calculate the position of both as thus.
[tex]Ian = \frac{6}{8} * 16 = \frac{96}{8} = 12[/tex]
[tex]Anna = \frac{3}{4} * 16 = \frac{48}{4} = 12[/tex]
So, both will be positioned on the 12th position.
The yellow dot represents Anna while the blue dot represents Ian

Penny paid off a loan with a simple interest rate of 11.2% in 6 months. What was the APR?
11.2%
9.6%
22.4%
19.2%
5.6%
Answer: 19.2%
Step-by-step explanation:
APR= (2(n)(r))/(n+1)
APR= 2(6)(0.112)/(6+1)
APR= 19.2
n= number of monthly payments (6)
r= the rate (11.2% or 0.112)
The solution is Option C.
The annual percentage rate of Penny is 22.4 %
What is Annual Percentage Yield?
The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest.
An APR is a number that represents the total yearly cost of borrowing money, expressed as a percentage of the principal loan amount.
Given data ,
Let the annual percentage rate be represented as A
Now , the value of A is
The simple interest rate R of Penny = 11.2 %
The time period of Penny n = 6 months
The annual percentage rate is calculated by = ( 12 x R ) / n
Substituting the values in the equation , we get
The annual percentage rate A = ( 12 x 11.2 ) / 6
The annual percentage rate A = 2 x 11.2
The annual percentage rate A = 22.4 %
Therefore , the value of A is 22.4 %
Hence , the annual percentage rate is 22.4 %

I need a answer very very quick
1÷2(2x+6)=4x-1
solve pls no links!!!
Answer:
Step-by-step explanation:
1 ÷ 2(2x+6) = 4x-1
[tex]\frac{1}{2(2x + 6)} = 4x -1[/tex]
[tex]\frac{1}{2*2x+2*6 } = 4x - 1 \\\\\frac{1}{4x + 12} = 4x - 1\\[/tex]
1 = (4x - 1)(4x + 12)
Use FOIL method.
1 = 4x * 4x + 4x *12 - 1 * 4x - 1*12
1 = 16x² + 48x - 4x - 12
1 = 16x² + 44x -12
0 = 16x² + 44x - 12 -1
16x² + 44x - 13 = 0
Mr.Lopez has 24 more books than Mrs.Hill if the ratio of their books is 7:4 how many books does Mrs. Hall have?
Answer:
Number of books with Mrs. Hall = 32
Step-by-step explanation:
Suppose that Mrs. Hill has [tex]x[/tex] books.
Also, Mr. Lopez has 24 more books than Mrs. Hill.
So,
Number of books with Mr. Lopez = [tex]x+24[/tex]
Ratio of their books = [tex]7:4[/tex]
Therefore,
[tex]\frac{x+24}{x}=\frac{7}{4}\\\\4(x+24)=7x\\\\4x+96=7x\\\\96=3x\\x=\frac{96}{3}\\\\x=32[/tex]
Number of books with Mrs. Hall = 32
