General admission to The American Museum of Natural History is $19.
a. If a group of 125 students visits the museum, how much will the group’s tickets cost?
b. If the group also purchases IMAX movie tickets for an additional $4 per student, what is the new total cost of all the tickets? Write an expression that shows how you calculated the new price.
Answer:
(a) $2,375.
(b) $2,875.
Step-by-step explanation:
We have been general admission to The American Museum of Natural History is $19.
(a). To find the total cost of tickets for a group of 125 students, we will multiply 125 by $19.
[tex]\text{The total cost of tickets}=\$19\times 125[/tex]
[tex]\text{The total cost of tickets}=\$2,375[/tex]
Therefore, the total cost of 125 tickets would be $2,375.
(b). We have been given that the group also purchases IMAX movie tickets for an additional $4 per student.
The total cost of one ticket would be the cost of museum ticket plus movie ticket that is [tex]\$19+\$4=\$23[/tex].
The new total cost of 125 tickets would be 125 times $23.
[tex]\text{The new total cost of tickets}=\$23\times 125[/tex]
[tex]\text{The new total cost of tickets}=\$2,875[/tex]
Therefore, the new total cost of 125 tickets would be $2,875.

[tex][/tex]How can you determine the coordinates of any image that is dilated with the center of dilation at the origin without graphing
Answer:
[tex](x,y)\rightarrow (kx,ky)[/tex]
Step-by-step explanation:
A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.
The dilation with the center of dilation at the origin and a scale factor of k has the rule
[tex](x,y)\rightarrow (kx,ky)[/tex]
This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).

If a+b-c=3 what is the value of 4(a+b-3)-(a+b+3c)?
3abc
Step-by-step explanation:
Final answer:
To find the value of 4(a+b-3)-(a+b+3c) given that a+b-c=3, we simplify to 3(a + b - c) - 12. Since a + b - c equals 3, the expression simplifies to -3.
Explanation:
The question provides the equation a + b - c = 3. To find the value of the expression 4(a+b-3)-(a+b+3c), we can simplify it using the given equation.
Let's break down the steps for simplification:
First, substitute the value of a + b - c from the given equation, which is 3, into the expression we want to simplify.Then, distribute the 4 across the first set of parentheses 4(a + b - 3) which becomes 4a + 4b - 12.Now, combining this result with the second part of the expression -(a + b + 3c) gives us 4a + 4b - 12 - a - b - 3c.Grouping like terms together and simplifying gives us 3a + 3b - 3c - 12 which is equivalent to 3(a + b - c) - 12.Since a + b - c = 3, the expression becomes 3(3) - 12, which simplifies to 9 - 12.Thus, the final value of the expression is -3.Tom has been a customer of the same bank foe two years and his income can change frommonth to month after paying bills. Tom places 250.00 a month in a two year CD. He notices that last year twice he withdrew 250.00 from his CD early to pay monthly bills. His bank charges a penalty for a early CD withdraw. His bank requires a minimum of 150.00 for regular savings accounts 750.00 for money markets, and 1,000 for CDs what would be the best strategy
Tom's best strategy would be to keep a minimum balance of $1,000 in his CD to meet his bank minimum requirement.
What is Tom's best strategy?From the given information, Tom's income can change from month to month and he needs to withdraw money from his CD to pay monthly bills, he should plan ahead and withdraw the necessary amount in one go to minimize the number of early withdrawals.
Withdrawing $250.00 from his CD every month for bills would result in multiple early withdrawals, incurring multiple penalties.
Thus, Tom's best strategy would be to keep a minimum balance of $1,000 in a separate CD for longer-term savings and avoid multiple early withdrawals.
Also he should keep the majority of his funds in a regular savings account or money market account for more flexibility in managing his irregular income and monthly expenses.

A large western state consists of 2691 million acres of land. Approximately 65% of this pand is federally owned how to find the answer?
Answer:
Step-by-step explanation:
What you need to do is take your 65% and put it over 100% like this: 65/100
Then, you take 2691 and put it into the denominator and put x on the top like this: x/2691
Then you need to put them equal to each other and cross multiply like this 65/100=x/2691
Multiply the 2691 by 65 and x by 100
to get 100x=2691(65)
Finally, multiply the 2691 by 65 and then divide that whole thing by 100 to get x.
x will be the land in acres and your final answer.
Good luck! Hope this was clear!
65% of the total acres of the large western state is approximately 1749.15 million acres.
To find the answer:
Calculate 65% of 2691 million acres.
Divide the result by 100 to get the amount federally owned.
Therefore, the federally owned land in the large western state is approximately 1749.15 million acres.

An ice cream sundae costs $1.75 plus an additional $0.35 for each topping. If the total
cost is $2.80, how many toppings did the sundae have?
Answer:
3
Step-by-step explanation:
$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80
1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75
2) Substract the numbers: 0.35x=1.05
3) Divide the both sides of the equation by 0.35
4) x=3
"The correct number of toppings on the sundae is 3.
To solve the problem, we first establish the cost of the ice cream sundae without any toppings, which is given as $1.75. We also know that each topping costs an additional $0.35. The total cost of the sundae with toppings is $2.80.
Let's denote the number of toppings as \( t \). The total cost of the sundae with toppings can be represented by the equation:
[tex]\[ \text{Total cost} = \text{Cost of sundae} + (\text{Cost per topping} \times t) \][/tex]
Substituting the known values into the equation, we get:
[tex]\[ 2.80 = 1.75 + (0.35 \times t) \][/tex]
To find the number of toppings [tex]\( t \)[/tex], we need to isolate [tex]\( t \)[/tex] on one side of the equation. We do this by subtracting the cost of the sundae from both sides of the equation:
[tex]\[ 2.80 - 1.75 = 0.35 \times t \][/tex]
[tex]\[ 1.05 = 0.35 \times t \][/tex]
Now, we divide both sides of the equation by the cost per topping to solve for [tex]\( t \)[/tex]:
[tex]\[ \frac{1.05}{0.35} = t \][/tex]
[tex]\[ t = 3 \][/tex]

since -2 and 3 are both rational, the sum and difference are both rational
since -2 and /3 are both rational, the sum and difference are both rational
since -2 is rational and /3 is irrational, the sum and difference are irrational.
Since /2 is rational and /3 is irrational, the sum and difference are irrational.
Answer:
Since -2 is rational and √3 is irrational, the sum and difference are irrational.
Step-by-step explanation:
Given equation,
[tex]x^2 + 4x + 1 =0[/tex]
[tex]x^2 + 4x = -1[/tex]
[tex]x^2 + 4x + 4 = -1+4[/tex]
[tex](x+2)^2 = 3[/tex]
[tex]x+2=\pm \sqrt{3}[/tex]
[tex]x=-2\pm \sqrt{3}[/tex]
Which is the solution of given equation.
Now, an integer is always a rational number ( that can be expressed as [tex]\frac{p}{q}[/tex], where, p and q are integers such that q ≠ 0 ),
So, -2 is a rational number,
Now, √3 can not be expressed as p/q so it is an irrational number,
We know that sum and difference of rational and irrational number is always irrational.
Thus, -2 + √3 and -2 - √3 are irrational.
Answer:
C
Since –2 is rational and StartRoot 3 EndRoot is irrational, the sum and difference are irrational.

The lengths of the sides of a triangle are 3, 3, 3 square root 2 Can the triangle be a right triangle?
The triangle can be a right triangle according to the Pythagorean theorem.
Explanation:To determine if a triangle is a right triangle, we can use the Pythagorean theorem. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (hypotenuse).
In this case, the lengths of the sides are 3, 3, and 3√2. Let's calculate: (3)² + (3)² = 18 and (3√2)² = 18. Since the two values are equal, the triangle satisfies the Pythagorean theorem and can be a right triangle.

2 step equations that equal 18
Answer:
(2x6)+6
2x6=12
12+6=18
Final answer:
Two-step equations that equal 18 can be solved by performing two operations to isolate the variable, such as subtracting and then dividing, or adding and then dividing.
Explanation:
A student is asking for examples of two-step equations that result in an answer of 18. Two-step equations involve performing two operations to solve for the unknown variable. For instance, a simple two-step equation could be x/2 + 5 = 14, where you would first subtract 5 from both sides to get x/2 = 9, and then multiply both sides by 2 to find x = 18.
Another example could be 2x - 4 = 32. To solve this equation, you would first add 4 to both sides, resulting in 2x = 36, and then divide both sides by 2 to get x = 18.
These examples help students understand how to manipulate equations using addition, subtraction, multiplication, or division to isolate the variable and solve the equation.
