Answer:Of the 600 people who visited the Amazing Art Museum on Tuesday, 45% were children.
How many children visited the museum on Tuesday?
To solve the problem, we can write the
percent
as
a
ratio
and then create an
equivalent ratio
.
On Tuesday,
270
children visited the museum.
The number of children visited the museum on Tuesday will be 270.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Total number of people = 600
And, There are 45% were children.
Now,
Since, 45% were children.
Hence, The number of children = 45% of 600
= 45/100 × 600
= 45 × 6
= 270
Thus, There are 270 children.

Solve for x. I WILL MARK BRAINLIEST.
Answer:
73 degreesStep-by-step explanation:
We all know that the inner degrees of a pentagon add up to 540°
thus we can use the following equation to solve for x:
33+140+2x+x+x+75=540
173+4x+75=540
248+4x=540
4x=540-248
4x=292
x=292/4
x=73
Thus, the answer is 73 degrees
Answer:
[tex]x=73[/tex]
Step-by-step explanation:
The sum of all interior angles of a pentagon is 540°.
[tex]33+140+2x+x+x+75=540[/tex]
Add all like terms.
[tex]33+140+4x+75=540[/tex]
[tex]4x+248=540[/tex]
Subtract 248 on both sides.
[tex]4x=540-248[/tex]
[tex]4x=292[/tex]
Divide 4 on both sides.
[tex]x=292/4[/tex]

If (2 − √3) is a zero of a quadratic polynomial then the other zero is __________.
Answer:
(2+sqrt3)
Step-by-step explanation:
Assertion(A): (2-√3) is one zero of the quadratic polynomial then the other zero will be (2+√3).
Reason (R): Irrational zeros (roots) always occurs in pairs.
What is the other zero of the polynomial if one zero of the quadratic polynomial?Since the given polynomial is a quadratic so it has only two zeros. Let other zero be x. Hence, the other zero is (2 -√3).
What is one zero of the quadratic polynomial?Polynomials that have only one zero mean both values of the variable are the same. This is the case of equal zeros of a quadratic equation. Let x be the variable of a quadratic equation and both zeroes of the quadratic equation are 2, i.e., equal roots.

A number cube is rolled. What is the likelihood that a number less than or equal to three is rolled?
The probability that a number less than or equal to three is rolled is 1/2.
Given that, a number cube is rolled, we need to find that what is the probability that a number less than or equal to three is rolled,
So, the probability = favorable outcomes / total outcomes
Here, the favorable outcome = 1, 2, 3 = 3
The total outcomes = 1, 2, 3, 4, 5, 6 = 6
So, the probability = 3/6 = 1/2
Hence, the probability that a number less than or equal to three is rolled is 1/2.

I run a book club with $n$ people, not including myself. Every day, for $365$ days, I invite five members in the club to review a book. What is the smallest positive integer $n$ so that I can avoid ever having the exact same group of five members over all $365$ days?
Answer:
Step-by-step explanation:
if we have n people and we want to do groups of 5, the total number of different combinations is:
[tex]c = \frac{n!}{(n - 5)!5!}[/tex]
find the smallest n such c > 365.
let's do it by brute force:
if n = 5, we have:
[tex]c = 5C_5 = 5[/tex]
if n = 6
[tex]c =6C_5 =6[/tex]
if n = 7
[tex]c = 7C_ 5= 21[/tex]
if n = 8
[tex]c = 8C_5 = 56[/tex]
if n = 9
[tex]C = 9!/(4!*5!) = 126[/tex]
so 9 is not enough, let's see N = 10
C = 10!/(5!*5!) = 252
10 is not enough, let's see with 11.
C = 11!/(6!*5!) = 462
So you need at least 11 members in the club.
Then the minimum number of members such we have more than 365 combinations is 11 members
Client need al least 11 members in the club.
Permutation and CombinationAccording to the question,
Group of five members, the combination will be:
→ [tex]c = \frac{n!}{(n-5)! \ 5!}[/tex]
By using Brute force,
If n = 5,
c = 5,
C₅ = 5
If n = 6,
c = 6,
C₅ = 6
If n = 7,
c = 7,
C₅ = 21
If n = 8,
c = 8,
C₅ = 56
Now,
If n = 9,
→ C = [tex]\frac{9!}{(4!\times 5!)}[/tex]
= 126
and, If n = 10,
→ C = [tex]\frac{10!}{(5!\times 5!)}[/tex]
= 252
and, If n = 11,
→ C = [tex]\frac{11!}{(6!\times 5!)}[/tex]
= 462
Then perhaps the minimal number of individuals required to have more than 365 possible combinations seems to be 11.
Thus the response above is correct.

The population of Greenbow, Alabama in 1995 was 200 people. Since then, the population has grown 2% per year. Model this situation with the proper equation and use that equation to predict the population of Greenbow in 2020.
Answer:
Equation is;
P = I(1 + r)^n
The population is 328
Step-by-step explanation:
Here we want to model the situation and use the modeled equation to predict population.
This follows an exponential pattern with similarity to the amount paid on a compound interest
Mathematically, we can have the equation as;
P = I(1 + r)^n
Where P is the population we want to calculate
I is the initial population in 1995 = 200 people
r is the rate of increase = 2% = 2/100 = 0.02
n is the difference in the number of years = 2020-1995 = 25
Thus the population would be;
P = 200(1 + 0.02)^25
P = 200(1.02)^25
P = 328.12
which is 328 approximately

Answer:
6
Step-by-step explanation:
There are 46 children attending the field trip.

what types of solutions does this equation have?
Answer:
Two imaginary solutions.
Step-by-step explanation:
In order to simplify the equation, we square root both sides. As the argument (value in the root) is negative, and we know that the square root function's domain is only positive numbers, we would have two imaginary solutions.
This would be positive/negative [tex]3i\sqrt{5}[/tex].
Another way to visualize this is by looking at the parabola's graph. Through algebraic manipulation, we know that the parabola is z^2 + 45. This parabola never crosses the x-axis. Therefore there are two solutions that are imaginary.
