The number of kids attending the circus is 1300.
Let's denote:
- ( K ) as the number of kids attending the circus.
- ( A ) as the number of adults attending the circus.
Given:
- The price of a kid's ticket is $2.50.
- The price of an adult's ticket is $6.
- The total ticket sales is $7,150.
- The number of kids attending the circus is twice the number of adults.
We can set up a system of equations based on the given information:
1. The total ticket sales:
[tex]\[ 2.50K + 6A = 7150 \][/tex]
2. The number of kids attending the circus is twice the number of adults:
[tex]\[ K = 2A \][/tex]
Now, we can solve this system of equations.
We can substitute the expression for ( K ) from equation 2 into equation 1:
[tex]\[ 2.50(2A) + 6A = 7150 \][/tex]
[tex]\[ 5A + 6A = 7150 \][/tex]
[tex]\[ 11A = 7150 \][/tex]
Now, solve for ( A ):
[tex]\[ A = \frac{7150}{11} \][/tex]
[tex]\[ A \approx 650 \][/tex]
So, the number of adults attending the circus is approximately 650.
Now, we can find the number of kids attending the circus using the expression we found for ( A ) in terms of ( K ):
[tex]\[ K = 2A \][/tex]
[tex]\[ K = 2 \times 650 \][/tex]
[tex]\[ K = 1300 \][/tex]
So, the number of kids attending the circus is 1300.

Write a word problem that can be solved using the equation 0x4=0. Then solve
The given mathematical equation, 0x4=0, can be turned into a word problem concerning a person with no money multiplying his funds. The result, as the equation suggests, is still no money, demonstrating that anything multiplied by 0 equals 0.
Explanation:Let's create a word problem for the equation 0x4=0. Suppose Jack has no money (0 dollars) and he multiplies his money by 4. How much money does Jack have now? The equation to represent this situation is 0x4=0. That is, 0 (Jack's money) times 4 equals 0. So, Jack still has no money. This shows that anything multiplied by 0 is always 0, a fundamental rule in mathematics.

a taxi driver earns $9 per 1 hour work. if he works 10 hours a day and in 1 hour he uses 2-liters petrol with price $1 for 1-liter. how much money does he earn in one day?
a. 90
b. 88
c. 70
d. 60
Final answer:
The taxi driver earns $70 in one day after deducting the cost of petrol from his gross income.
Explanation:
To calculate the taxi driver's earnings, we need to consider his hourly wage, the number of hours worked, and the cost of petrol used during the day. The driver earns $9 per hour and works for 10 hours a day. Thus, his total gross income for the day is $90 (9 dollars/hour times 10 hours). However, he also uses petrol for which he incurs a cost. He uses 2 liters per hour, and since petrol costs $1 per liter, he spends $2 per hour on petrol. Over 10 hours, he thus spends $20 on petrol (2 dollars/hour times 10 hours). To find his net earning, we subtract the petrol cost from the gross income: $90 - $20, which equals $70.
1.5x=3 whats the answer
Answer:
To find the value for x you need to get x by itself
To do this we need to do the opposite of what it is showing
1.5 times x the opposite would be dividing
So we need to divide 1.5 from each side (what you do to one side you do to the other)
1.5x/1.5=x (x is now by itself)
3/1.5=2

Answer:
the 11th week.
Step-by-step explanation:
the expression for the markdown on the 8th week is p-.15p=.85p since it will get marked down 15% on the 8th week. the expression for the additional markdowns is p-.05p=.95p since it will get marked down an additional 5% every week after the 8th week.
On the 8th week it will be marked down to .85(150) = 126.50.
9th week: .95(127.50) = 121.13
10th week: .95(121.13) = 115.07
11th week: .95(115.07) = 109.32
109 is under 110 therefore it is the 11th week.

what is 1/4 + 3/7? please explain how to solve it.
Answer: 19/28
Step-by-step explanation: Notice that 1/4 and 3/7 are unlike fractions. Our first step when adding unlike fractions is to get a common denominator.
The common denominator of 4 and 7 will be the least common multiple of 4 and 7 which is 28.
To get a 28 in the denominator of 1/4, we multiply the numerator and the denominator by 7 which gives us 7/28.
To get a 28 in the denominator of 2/7, we multiply the numerator and the denominator by 4 which gives us 12/28.
Now to add like fractions or fractions that have the same denominator, we simply add the numerators and keep the original denominator.
So here, we have 7 + 12 which is 19 and we put this over our original denominator which is 28.
So, 1/4 + 3/7 = 19/28.
The sum of two numbers is thirty seven. Using x to represent the larger of two numbers, translate “the difference between nine more than twice the larger number and the sum of the smaller number and three” into a variable expression
Two numbers = 37
Larger number is x, so the smaller number is 37 - x:
x + (37 - x) = 37
“The difference” is subtraction, so we are subtracting the smaller and larger number.
“Nine more than twice the larger number” looks like 9 + 2x, and “the sum of the smaller number and three” looks like (37 - x) + 3. Because this is subtraction, we would write (9 + 2x) - (37 - x) + 3. First, distribute the negative sign:
-(37 - x) = -37 + x
We then simplify:
9 + 2x - 37 + x + 3 (subtract 3)
9 + 2x - 34 + x
-25 + 2x + x (subtract 8 and 34 then add 2x and x)
-25 + 3x
The variable expression for the given problem, where x is the larger number and the sum of two numbers is thirty-seven, is 2x + 9 - (37 - x + 3).
The student is asking to translate a word problem into a variable expression. The problem states that the sum of two numbers is thirty-seven and defines the larger number as x. We want to find the expression for "the difference between nine more than twice the larger number and the sum of the smaller number and three". Knowing that the sum of the two numbers is thirty-seven, we can represent the smaller number as 37 - x. Therefore, the expression would be 2x + 9 - (37 - x + 3).
A math class has 5 girls and 5 boys in the seventh grade and 5 girls and 7 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition. What is the probability that the students she selects are both girls? Write your answer as a fraction in simplest form.
Final answer:
The probability that the students selected are both girls is 5/24.
Explanation:
To find the probability that both students selected are girls, we need to calculate the probability of selecting a girl from the seventh grade and a girl from the eighth grade and then multiply those probabilities together.
The probability of selecting a girl from the seventh grade is 5 girls out of 10 students, which can be expressed as 5/10 or 1/2.
The probability of selecting a girl from the eighth grade is 5 girls out of 12 students, which can be expressed as 5/12.
To find the probability of both events happening, we multiply the probabilities together: (1/2) * (5/12) = 5/24.
Therefore, the probability that the students selected are both girls is 5/24.
A suit with an original price of $300 was marked down 30%. You have a coupon good for an additional 20% off. What is the suits final cost?
The suit's final cost after a 30% markdown and an additional 20% off coupon is $168.
Explanation:To find the suit's final cost, we first calculate the price after the 30% markdown. Subtracting 30% of $300 gives us: $300 - ($300 x 0.30) = $210. Next, we apply the additional 20% off coupon. Subtracting 20% of $210 gives us: $210 - ($210 x 0.20) = $168. Therefore, the suit's final cost is $168.

RSM QUESTION NEED HELP!!!!!! A biker traveling at his usual speed can go from his house to work in 4 hours. When the weather is bad, he travels 6 miles per hour slower, and it takes him half an hour more. How far is his work from his house?
=======================================
Work Shown:
d = distance from work to his house
x = speed when weather is good
y = speed when weather is bad
y = x-6 since he travels 6 mph slower
------------------------
On a good weather day, he travels for 4 hours and goes at x mph
distance = rate*time
d = r*t
d = x*4
d = 4x
----------------------
On a bad weather day, he travels 4.5 hours (half hour more than 4 hrs) and goes at y = x-6 mph
d = r*t
d = y*4.5
d = 4.5y
d = 4.5(x-6) .... replace y with x-6
d = 4.5x-27 .... distribute
----------------------
The values of d for both equations are the same, as the biker is traveling the same distance. So we can equate the two right hand sides (RHS) and solve for x.
4.5x-27 = 4x
4.5x-4x = 27
0.5x = 27
x = 27/0.5
x = 54
The biker's speed on a good weather day is 54 mph.
A bad weather day's speed would be y = x-6 = 54 - 6 = 48 mph.
----------------------
Now compute the value of d
d = 4x
d = 4*54
d = 216
The biker travels 216 miles on a good weather day
or,
d = 4.5*y
d = 4.5*48
d = 216
the biker travels that same distance on a bad weather day.
