Hello I need immediate help please?
Dion bought tickets for the fun park so that he and his friends would each have the same number of tickets. There are enough tickets so that each person can ride the go-carts once, play video games three time, and play laser tag twice.
When Dion purchased the tickets for himself and his eight friends, he realized that he could purchase ticket books, individual tickets, or a combination of books and individual tickets. Dion figured out the cheapest way to buy tickets for his group. What was the total cost?
Please I would appreciate it a lot ❤️
Answer:
25
Step-by-step explanation:
;\
The required cheapest way to buy tickets is by buying 7 ticket books and 3 individual tickets.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Consumption of tickets for each person can ride the go-carts once, play video games three times, and play laser tag twice,
= 4 + 1*3 * 2*6
= 19
So each person conceded 19 tickets,
Total ticket conceded by 9 persons,
= 19 * 9
= 171 tickets
Now the cheapest option is given by,
A ticket book consists of 24 tickets so,
Dividing 171 by 24 the quotient will be the number of books and the remainder will be the individual tickects for the cheapest purchase,
= 171 / 24
= 7 + 3 / 24
quotient = 7
remainder= 3
Thus, the required cheapest way to buy tickets is by buying 7 ticket books and 3 individual tickets.

Is it possible to have a triangle with two right angles? Explain your reasoning.
Answer:
No
Step-by-step explanation:
For something to be considered a triangle, the sum of its angles must be 180 degrees. Right angles are 90 degrees. And since triangles must have 3 angles, it could not work. 80+80 exceeds 180.
exponents and roots are what operations
Answer:
An exponent
Step-by-step explanation: So if we have 83, we want to multiply three 8s, or 8 * 8 * 8. A root is basically the opposite. We're trying to find the number that we multiply by itself a certain number of times to get the number under the radical sign.
Find the distance between the following two points:

(-5,0) and (-2,-1)
Answer:
[tex]d = \sqrt{10}[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(-2-(-5))^2+(-1-0)^2}[/tex]
[tex]d = \sqrt{(-2+5)^2+(-1)^2}[/tex]
[tex]d = \sqrt{(3)^2+1}[/tex]
[tex]d = \sqrt{9+1}[/tex]
[tex]d = \sqrt{10}[/tex]

Answer:

Step-by-step explanation:
The scores on a statistics test had a mean of 81 and a standard deviation of 9. One student was absent on the test day and his score wasn't included in the calculation. If his score of 78 was added to the distribution of scores, what would happen to the mean and standard deviation?
A) Mean will increase, standard deviation will decrease.
B) Mean will increase, standard deviation will increase.
C) Mean will decrease, standard deviation will stay the same.
D) Mean will decrease, standard deviation will increase.
E) Mean will decrease, standard deviation will decrease.
Answer: E) Mean will decrease, standard deviation will decrease
Step-by-step explanation:
Initial mean = 81
Initial standard deviation = 9
New score = 78
Taking a look at the initial mean(averahe) score, which is 81 and the new score to be added to the initial scores, the initial average is greater than the new score. Hence, this will result in a decrease in the new mean score after adding the new score of 78.
Also, taking a look at the standard deviation which is 9, we can conclude that the variability in initial scores from the mean scores is high. However, the new score of 78 and the initial mean are very close, and tend to low variation. Hence, adding the new score will lead to a decrease in variability and hence a decrease in the value of standard deviation.

2(u-1)-6= -5(-4u+4) -3u
Answer:
u = 4/5
Step-by-step explanation:
Expand
2u - 2 - 6 = 20u - 20 - 3u
Rearrange with like terms on either side
12 = 15u
u = 4/5
Answer:
u=4/5
Step-by-step explanation:
First, parentheses/multiply on both sides.
2u-2-6=20u-20-3u <--- two negatives make a positive
Next, add/subtract like terms.
2u-8=17u-20
Then, add 8 to both sides.
2u=17u-12
Finally, get "u" by itself. Subtract "17u" to both sides and then divide "-15" to both sides
-15u=-12
u=4/5
Which equation represents a direct variation?
y = 0.5x

4(6x - 10) = 8x + 40
Answer:
5
Step-by-step explanation:
24x-40=8x+40
plus 40
24x=8x+80
then u subtract 8
then u get 16x
then 80 divied by 16
u get 5
Answer:
x = 5
Step-by-step explanation:
4(6x -10) = 8x + 40
24x - 40 = 8x + 40
now were going to get the variable and the numbers on different sides
24x - 40 + 40 = 24x
8x + 40 - 8x = 40
24x - 8x = 16x
40 + 40 = 80
16x = 80
now divide each side by 16
16x / 16 = x
80 / 16 = 5
x = 5
