Step-by-step explanation:
A stadium has 45,000 seats. Seats sell for $28 in Section A, $24 in Section B, and $20 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,139,600 from each sold-out event. How many seats does each section hold?
Answer:
section A = 22,500 seatssection B = 14,900 seatssection C = 7,600 seatsStep-by-step explanation:
given:
stadium has 45,000 seats.
section A = $28 per ticket
section B = $24 per ticket
section C = $20 per ticket
$1,139,600 from each sold out event
Seats on A = Seats B + Seats C
find:
How many seats does each section hold?
solution:
45,000 = A + B + C eq. 11,139,600 = 28A + 24B + 20C eq. 2since A = B + C, substitute A into eq. 1
45,000 = A + B + C45,000 = (B + C) + B + C45,000 = 2B + 2C45,000 - 2C = 2BB = 45,000 - 2C2
B = 22,500 - C eq. 3since A = 22,500
B = 22,500 - C
substitute A and B into eq. 2 to get C
1,139,600 = 28A + 24B + 20C1,139,600 = 28(22,500) + 24(22,500 - C) + 20C1,139,600 = 630,000 + 540,000 - 24C + 20C1,139,600 - 630,000 - 540,000 = -24C + 20C-30,400 = -2CC = 30,4004
C = 7,600now plugin the value of C=15,200 into eq. 3
B = 22,500 - CB = 22,500 - 7,600B = 14,900therefore, the number of seats on each sections are:
seats A = 22,500
seats B = 14,900
seats C = 7,600
Proof:
45,000 = A + B + C45,000 = 22,500 + 14,900 + 7,60045,000 = 45,000 √
1,139,600 = 28A + 24B + 20C1,139,600 = 28(22,500) + 24(14,900) + 20(7,600)1,139,600 = 630,000 + 357,600 + 152,0001,139,600 = 1,139,600 √Megan Jordan and Katie babysat and earned a total of $65.55 if they split the earnings evenly how much would each person earn

Peanut allergies are becoming increasingly common in Western countries. Some evidence points to the timing of peanuts! first introduction in the diet as an influential factor, raising the question of whether pediatricians should recommend early exposure or avoidance. A study enrolled infants with a diagnosed peanut allergy and randomly assigned them to either completely avoid peanuts or consume peanuts in small amounts regularly until they reached 60 months of age. At the end of the study, 18 of the 51 infants who had avoided peanuts were still allergic to peanuts. In contrast, 5 of the 47 infants who had consumed peanuts were still allergic to peanuts. Do the data indicate that one approach is more beneficial? Follow the four‑step process.
STATE: What is the question we are asking?
A. Does early exposure to peanuts better reduce peanut allergy in children with a known allergy to peanuts?
B. Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?
C. Should all children under the age of 60 months avoid peanuts or only eat them in small amounts?
D. Should all children under 60 months eat peanuts regularly in small amounts?
Answer:
B. Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?
Step-by-step explanation:
Remember we are told there's already a question whether pediatricians should recommend early exposure or avoidance. Thus, the research question should answer these two issues (early exposure or avoidance).
Hence, the question we are asking is: Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?

This cost can be calculated using the formula C=230.00+0.85p, where p represents the number of magnets produced and C is the cost. Use the formula to calculate the cost of producing 1600 magnets.
Bob did chores for his neighbor. The first day he earned $8. Then he earned $10 a day for
two weeks. If he took one day off each week, how much did he earn?
Answer: $128
Step-by-step explanation: So first Bob earned 8 dollars. Then he started earning 10 dollars a day every week for 2 weeks. that would have been 148 dollars (plus the 8 dollars he earned in the beginning), but he took a break once a week, subtracting 20 dollars from his pay, giving him 128 dollars in total.

Luis uses cubes to represent each term of a pattern based on a recursive function. The recursive function defined is f(n + 1) = f(n) + 4, where n is an integer and n ≥ 2. The number of cubes used in each of the first two figures is shown below. How many cubes does Luis use in the third, fourth, and fifth figures of the pattern? Fill in the blanks.
Figure 1: 9 cubes
Figure 2: 13 cubes
Figure 3:
cubes
Figure 4:
cubes
Figure 5:

Answer:
17 cubes 21 cubes25 cubesStep-by-step explanation:
Given function
f(n + 1) = f(n) + 4The first two values are given
f(1) = 9 f(2) = 13The following terms are
f(3) = 13 + 4 = 17
Figure 3 = 17 cubesf(4) = 17 + 4 = 21
Figure 4 = 21 cubesf(5) = 21 + 4 = 25
Figure 5 = 25 cubesAs per Luis' pattern:
Figure 3: 17 cubes.
Figure 4: 21 cubes.
Figure 5: 25 cubes.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
The recursive function f(n + 1) = f(n) + 4 means that to find the number of cubes in the next figure, Luis needs to add 4 cubes to the number of cubes in the previous figure.
In Figure 1, there are 9 cubes.
To get Figure 2, Luis adds 4 cubes, which results in 13 cubes.
To find the number of cubes in Figure 3, Luis needs to add 4 cubes to the number of cubes in Figure 2, which results in 17 cubes.
To find the number of cubes in Figure 4, Luis adds 4 to the number of cubes in Figure 3, resulting in 21 cubes.
To find the number of cubes in Figure 5, Luis adds 4 cubes to the number of cubes in Figure 4, which results in 25 cubes.
Therefore, the number of cubes in the third, fourth, and fifth figures is 17, 21, and 25, respectively.

The distance from Chicago to NY is 794 miles what is 794 rounded to nearest hundred
Answer:
794 rounded to the nearest hundred is 800.
Step-by-step explanation:
The round off value of 794 is 800 miles.
What is Round off?While rounding is a broad concept, we typically use the terms 'round up' or 'round down' to indicate whether the number has increased or reduced following rounding. When the rounded number is increased, the supplied number is said to be rounded up, and when it is dropped, it is said to be rounded down.
We have,
The distance from Chicago to NY is 794 miles.

A company paid $48 for 2 cases of printer paper. Each case contained 12 packages of paper. Next month the company’s office manager needs to order 180 packages of the same paper. If the price per package does not change, what would be the total cost of next month’s order?
Answer:
$360.
Step-by-step explanation:
First we need to find how much it costs for a single case of printer paper.
48 ÷ 2 = 24
It costs $24 to buy one case of 12 packages.
Now we have to figure out how many cases we will need to buy for the total amount of 180 packages.
I will divide 12 from 180.
180/12 = 15.
You will need to buy 15 cases to get 180 packages.
Now to find the cost, we have to multiply.
x = 15 (amount of cases)
y = $24 (price of case)
z = How much it costs.
[tex]x * y=z[/tex]
Substitute:
[tex]15*24=z[/tex]
Multiply:
[tex]15 * 24= 360[/tex]
[tex]z=360[/tex]
If the price does not change, the total cost of next month's order will be $360.
Determine whether y varies directly with x. If so, find the constant of the variation.
y=7/x
Answer:
Direct variation is modeled by
... y = k·x
Then the value of k can be found by finding the ratio of any corresponding pair of numbers from your table. I find it convenient to choose the one where x=10, so the math is easy to do mentally.
... y/x = k
... 16/10 = k = 1.6
Then the equation is
... y = 1.6x
_____
Checking the other values in the table, we find that this equation fits all of them, so you do have direct variation.Step-by-step explanation:

Step-by-step explanation: Based off of looks alone, one could conclude that 3x is approximately 0.5 degrees larger than 2x, 2x is approximately 90 degrees, and that x is approximately half of 2x. so based purely off of observation, it appears that x is approximately 45 degrees. you can multiply x by the number by in it in each instance.
x=45, 2x=90, and 3x=135
Please check if you have a protractor.
Answer:
The value of x is 45°
Step-by-step explanation:
We could conclude that 3x is approximately 0.5 degrees larger than 2x, 2x is approximately 90 degrees, and that x is approximately half of 2x.
x = 45°
2x = 2(45) = 90°
