Answer:
ferris wheel: 2
roller coaster: 4
Step-by-step explanation:
Variables
y = ferris wheel tickets
x = roller coaster tickets
Two equations
5y + 4x = 26
5y + 3x = 22
Using Elimination (minus the top and bottom)
We get:
x = 4 (because 5y - 5y is zero, 4x - 3x is x, and 26 - 22 is 4)
Since the roller coaster price is know, you can sub it into any of the two equations and fine ferris wheel price.
5y + 3(4) = 22
5y + 12 = 22
5y = 10
y = 2
Therefore:
ferris wheel charges 2 tickets
roller coaster charges 4 tickets
Answer:
Step-by-step explanation:

how many three-digit numbers satisfy the property that the middle digit is the absolute value of half the difference of the first and the last digits?
A total of [tex]10 + 4 + 4 = \boxed{18}[/tex] three-digit numbers that satisfy the given property.
Let the three-digit number be written as abc, where a, b, and c are the hundreds, tens, and ones digits, respectively. We want b to be the absolute value of half the difference between a and c. In other words, we want b = [tex]\left|\frac{a-c}{2}\right|.[/tex]
Since a, b, and c are digits, we know that [tex]0 \leq a, b, c \leq 9.[/tex] Since b is the absolute value of a number, we know that b is non-negative.
Case 1: [tex]a \geq c[/tex]
If [tex]a \geq c[/tex], then[tex]b = \frac{a-c}{2}[/tex]. Since b must be non-negative, we have two
subcases to consider:
Subcase 1: a=c
In this subcase, b=0, which means that the number abc is of the form a00, where [tex]0 \leq a \leq 9[/tex]. There are 10 such numbers.
Subcase 2: a>c
In this subcase, [tex]b = \frac{a-c}{2}[/tex] is a positive integer. Since a and c must have the same parity (i.e., they are either both even or both odd), we have two
sub-subcases to consider:
Sub-subcase 1: a and c are both even
In this sub-subcase, a and c are both integers between 0 and 8 inclusive (since they are even and cannot be equal to 0 or 9). There are 4 such pairs of values for a and c: (2,0), (4,2), (6,4), and (8,6). For each pair, the value of b is uniquely determined, so there are 4 corresponding numbers abc.
Sub-subcase 2: a and c are both odd
In this sub-subcase, a and c are both integers between 1 and 9 inclusive (since they are odd and cannot be equal to 0 or 8). There are 4 such pairs of values for a and c: (9,7), (7,5) , (5,3), and (3,1). For each pair, the value of b is uniquely determined, so there are 4 corresponding numbers abc.
Case 2: a < c
If a < c, then[tex]b = \frac{c-a}{2}[/tex]. Since b must be non-negative, we have only one
subcase to consider:
Subcase: c- a is even
In this subcase, c-a is an even integer between 2 and 8 inclusive (since it cannot be equal to 0 or 9). There are 4 such even integers: 2, 4, 6, and 8. For each even integer, the values of a and c that satisfy c-a are uniquely determined, and the value of b is then uniquely determined. So there are 4 corresponding numbers abc.
Putting everything together, we have a total of [tex]10 + 4 + 4 = \boxed{18}[/tex] three-digit numbers that satisfy the given property.

Camden is working two summer jobs, making $10 per hour babysitting and making $18 per hour lifeguarding. In a given week, he can work no more than 14 total hours and must earn no less than $180. If Camden worked 9 hours lifeguarding, determine the minimum number of whole hours babysitting that he must work to meet his requirements. If there are no possible solutions, submit an empty answer.
Camden must work a minimum of 2 hours babysitting and 9 hours of lifeguarding to meet the requirements.
What is the solution to the equation?A solution to an equation is a number that can be substituted for the variable to provide a true number statement.
Let's call the number of hours Camden works babysitting "x".
We know that x + 9 (hours of lifeguarding) cannot be more than 14 and that his total earnings must be at least $180. So we can write two equations based on these conditions:
x + 9 ≤ 14 (hours worked can't exceed 14)
10x + 18 × 9 ≥ 180 (earnings must be at least $180)
Now we can substitute the first equation into the second:
10x + 18 × 9 ≥ 180
10x + 162 ≥ 180
10x ≥ 18
x ≥ 1.8
Since x has to be a whole number of hours, we round up to find that Camden must work at least 2 hours babysitting.
So, Camden must work a minimum of 2 hours babysitting and 9 hours of lifeguarding to meet the requirements.

What is the Two Tangents Exterior Angle Theorem?If you draw two tangents from a point outside a circle, the size of the angle they form is equal to half of the difference between the sizes of the two arcs they intercept inside the circle, based on the Two Tangents Exterior Angle Theorem.
Therefore, we have:
6x - 12 = 1/2[(-12 + 21x) - (12x - 24)] (according to the Two Tangents Exterior Angle Theorem)
Solve for x:
6x - 12 = 1/2[(-12 + 21x - 12x + 24)
2(6x - 12) = -12 + 21x - 12x + 24
12x - 24 = 9x + 12
12x - 9x = 24 + 12

They are skating in the same direction, how long will it take Sam to catch up to tom
will take Sam 2.72 seconds to catch up to Tom.
Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
To find out how long it will take Sam to catch up to Tom, we can use the following formula:
time = distance / (rate of Sam- the rate of Tom)
In this case, the distance is 120 ft (the distance between Tom and Sam when they start speed skating) and rate of Sam is 50 ft/sec, and the rate of Tom is 44 ft/sec.
Plugging these values into the formula, we get:
time = 120 / (50 - 44) = 120 / 6 = 20

Answer: Width = 45 feet; Length = 15 feet;
Step-by-step explanation: Start by substituting 3w for the length because it says that in the problem. We know that 2(L+W) equals the perimeter. Since we substituted 3w for length we get 8w for the perimeter. Divide 120 by 8 to find that the width is 15 feet and plug it into 3w to get the length of 45 feet.
Answer:
45 feet and 15 feet are the length and width
Step-by-step explanation:
P = 120 feet
a (length) = 3 * b (width)
P = 2 * (a + b)
P = 2 * (3b + b)
P = 2 * 4b
P = 8 * b
=> 8b = 120 feet
P = 120 feet
b = 120 / 8
b = 15 feet
a = 3 * b
a = 3 * 15

a student has scores of 77, 77.25, and 81.25 on his first three tests. he needs an average of at least 80 to earn a grade of b. what is the minimum score that the student needs on the fourth test to ensure a b?
The student needs a minimum score of 84.5 on the fourth test to ensure a grade of B.
To find the minimum score the student needs on the fourth test, we can use the formula for the average of four numbers:
Average = (sum of the numbers) / 4
We know that the student needs an average of at least 80 to earn a grade of B, and we also have the scores for the first three tests: 77, 77.25, and 81.25. So, we can set up the equation:
80 = (77 + 77.25 + 81.25 + x) / 4
where x is the score the student needs on the fourth test. Solving for x:
80 = (235.5 + x) / 4
320 = 235.5 + x
x = 320 - 235.5
x = 84.5
So, the student needs a minimum score of 84.5 on the fourth test to ensure a grade of B.

A radioactive compound with mass 320 grams decays at a rate of 27% per hour. Which equation represents how many grams of the compound will remain after 4 hours?
The equation represents how many grams of the compound will remain after 4 hours m(4) = 0.285m₀
Radiation and decay are important concepts in nuclear physics. The rate at which radioactive compounds decay is measured in terms of half-life and the decay constant.
To solve this problem, we can use the exponential decay equation, which describes the rate of decay of a radioactive substance.
In this scenario, we are interested in finding the remaining mass of the radioactive compound, which can be obtained by multiplying the number of remaining atoms by the atomic mass of the substance. The equation for the remaining mass is:
m(t) = N(t) x m
where:
m(t) represents the mass of the radioactive substance remaining at time t.
N(t) is the number of radioactive atoms remaining at time t.
m is the atomic mass of the substance.
To determine the values of N0 and λ for our radioactive compound, we can use the decay rate given in the problem. If the compound decays at a rate of 27% per hour, it means that the remaining fraction of the substance after each hour is 0.73 (i.e., 100% - 27% = 73%). Therefore, the decay constant can be calculated as follows:
ln(0.73) = -λ
λ = 0.312
Next, we can use the initial mass of the compound (320 grams) and the exponential decay equation to find the remaining number of atoms at 4 hours:
[tex]N(4) = N_0 \times e^{-0.312 x 4}[/tex]
N(4) = N₀ x 0.285
Since we don't know N₀, we can express it in terms of the initial mass and the atomic mass:
N₀ = m₀ / m
where:
m₀ is the initial mass of the radioactive compound.
m is the atomic mass of the substance.
Substituting this into the previous equation, we get:
N(4) = (m₀ / m) x 0.285
Finally, we can use the equation for the remaining mass to find the answer:
m(4) = N(4) x m
m(4) = (m₀ / m) x 0.285 x m
m(4) = 0.285m₀

Rain is falling at a rate of 4/5 inches every 2/3 hours. What complex fraction can you use to find the unit rate in inches per hour?
the unit rate is 6/5 inches per hour, or approximately 1.2 inches per hour.
Finding unit rate in inches per hour
The unit rate in inches per hour can be found by dividing the amount of rain falling per unit of time by the corresponding unit of time. In this case, we have 4/5 inches falling every 2/3 hours, so we can find the unit rate by dividing 4/5 by 2/3:
(4/5) / (2/3) = (4/5) X (3/2) = 6/5 inches per hour
So the unit rate is 6/5 inches per hour, or approximately 1.2 inches per hour.

Let ∠1 , ∠2 , ∠3 , and ∠4 have the following relationships. ∠1 and ∠2 are vertical angles. ∠3 and ∠4 are right vertical angles. ∠3 is adjacent to both ∠1 and ∠2 . What is the sum of the measure of ∠4 and the measure of ∠1 minus the measure of ∠2 ?
Answer:
Since ∠1 and ∠2 are vertical angles, they have equal measure. And since ∠3 and ∠4 are right vertical angles, they have measure 90° each.
Since ∠3 is adjacent to both ∠1 and ∠2, we can say that:
∠1 + ∠3 = 180°
∠2 + ∠3 = 180°
Adding these two equations together:
∠1 + ∠2 + 2∠3 = 360°
Substituting the values we have:
∠1 + ∠2 + 2(90°) = 360°
∠1 + ∠2 + 180° = 360°
Solving for ∠1 + ∠2:
∠1 + ∠2 = 180° - 180° = 0°
Finally, the sum of the measure of ∠4 and the measure of ∠1 minus the measure of ∠2 is:
∠4 + (∠1 - ∠2) = 90° + (∠1 - 0°) = 90° + ∠1
So the answer is 90° + ∠1.
5. A bag holds 4 white, 6 red, and 2 blue marbles. You choose a marble without looking, put it aside, and choose
another marble without looking. Find the probability of removing a white marble followed by a blue marble.
The required probability of removing a white marble followed by a blue marble is 2/33.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
There are 12 marbles in the bag in total, so the probability of selecting a white marble on the first draw is 4/12 or 1/3.
After the first marble is put aside, there are now 11 marbles in the bag, with 2 of them being blue. Therefore, the probability of selecting a blue marble on the second draw is 2/11.
To find the probability of selecting a white marble followed by a blue marble, we need to multiply the probability of the first event (selecting a white marble) by the probability of the second event (selecting a blue marble):
P(white, then blue) = P(white) x P(blue|white)
P(white, then blue) = (1/3) x (2/11)
Simplifying:
P(white, then blue) = 2/33
Therefore, the probability of removing a white marble followed by a blue marble is 2/33.
