Respuesta:
6200
Explicación paso a paso:
Dado que :
Cantidad total que tiene Elena:
Su dinero + cantidad dada por su madre = (7500 + 1500) = 9000
Gastos de Elena:
Admisión = 6500
Almuerzo = 4750
Recuerdos = 3950
Gastos totales = (6500 + 4750 + 3950) = 15200
Cantidad restante:
Gastos totales - Cantidad que Elena tiene
(15200 - 9000) = 6200
Evaluate the expression!!
The given expression is equivalent to 22 for x = 17 and y = 12.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context. Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the expression as follows -
2x - y
For x = 17 and y = 12, we can evaluate the expression as -
2 x 17 - 12
34 - 12

How do you find the area of an acute triangle without height?
The area of the triangle is equal to the squareroot of 10(10-5)(10-7)(10-8), which is equal to 24.
The area of an acute triangle without height can be calculated using Heron's Formula. Heron's Formula states that the area of a triangle is equal to the squareroot of s(s-a)(s-b)(s-c) where s is the semi-perimeter of the triangle and a, b, and c are the lengths of the three sides.
To find the area, first calculate the semi-perimeter of the triangle. The semi-perimeter is equal to one-half the sum of the three sides. For example, if the lengths of the three sides of a triangle are 5, 7, and 8, the semi-perimeter is equal to 5 + 7 + 8 divided by 2, which is equal to 10.
Next, plug the values into Heron's Formula. Using the same triangle as an example, the area of the triangle is equal to the squareroot of 10(10-5)(10-7)(10-8), which is equal to 24.
Finally, calculate the area of the triangle by taking the square root of 24, which is equal to 4.9. Therefore, the area of the triangle is 4.9 square units.

If an investment company pays 6% compounded continuesly, how much should you deposit now to have $10,000 5 years from now?
The amount of money should you deposit now to have $10,000 5 years from now is $7407.
What is compound interest?Theoretically, continuously compounded interest means that interest is continuously earned on an account balance as well as reinvested into the balance to increase future interest earnings.
Given that If an investment company pays 6% compounded continuously and $10,000 for 5 years.
The amount of money invested will be calculated by the formula below,

Para festeja su cumpleaños,Nancy compró 15 paquetes de pizzetas. Si cocinó 288 pizzetas, cuántos paquetes completos le quedaron?
Answer:
Nancy consumió 12 paquetes de pizzetas y le quedaron 3 paquetes completos.
Step-by-step explanation:
En primer lugar, debemos descomponer el número total de pizzas como una multiplicación de números primos. Al realizar la descomposición factorial tenemos que:
[tex]288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3[/tex]
Entonces, los familia de divisores de 288 es el siguiente conjunto:
[tex]D_{288} = \{2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144 \}[/tex]
Si tanto la cantidad de paquetes de pizzetas y la cantidad cocinada de pizzetas son números enteros y positivos, siendo la última mucho mayor. Entonces, la cantidad de pizzetas debe ser un número entero y la cantidad de paquetes gastados menor a la cantidad de paquetes comprados y el número entero más cercano a esa cantidad. Entonces, concluimos que Nancy se gastó 12 paquetes de pizzetas, quedándole 3 paquetes completos.

Both Phoebe and Connor are trying to maximize their lifetime income. Each has a different plan on how to do this best:
Phoebe claims that she wants a career with no college or trade school requirements because she could save the money for retirement rather than spending it on education. She estimates her average yearly salary at $35,000 per year with no post-secondary education requirements.
Connor claims post-secondary education will help him get a career with a higher salary and more benefits that he can use in retirement, so the education costs will more than pay for themselves. Connor estimates paying $80,000 for his post-secondary education and an average yearly salary of $60,000 per year after he earns his college degree.
Which statement about their claims is correct?
A. Phoebe is correct because a college education is overly expensive and is almost a waste of money.
B. Phoebe is correct because she will not be spending tuition dollars on college while earning $140,000 during the four years it would take to earn an undergraduate degree. College graduates would never be able to make up that difference in earnings.
C. Connor is correct because it is likely that the increased income and better benefits he will earn throughout his career will outweigh the $80,000 and four years he invests in his college education.

What quadrant does (-a,b) belong
Coordinate (-a , b ) belongs to second quadrant.
What is a Quadrant?The axes (x-axis and y-axis) of a two-dimensional Cartesian plane system divide the plane into four infinite regions called quadrants. The horizontal line or x-axis and vertical line or y-axis intersect each other at the right angle. The intersection of two lines is known to be the reference point. All the measurement is done by taking this point as the reference (or starting point) in the coordinate system.
"A quadrant is simply defined as the region of a cartesian plane formed when the x-axis and y-axis intersect each other."
Given, Coordinate ≡ (-a , b)
1st Quadrant: The upper right-hand corner of the graph is the first quadrant. In this quadrant the values of x and y both are positive.
2nd Quadrant: The upper left-hand corner of the graph is the second quadrant. In this quadrant, the value of x is negative whereas the value of y is positive.
3rd Quadrant: The lower left-hand corner of the graph is the third quadrant. It contains the negative values of both x and y.
4th Quadrant: Finally, the fourth quarter is at the lower right-hand corner, which has a positive value of x and a negative value of y.
Hence, by the above observation, given coordinate (-a, b) belongs to the 2nd quadrant.

The area of the yellow region will be [tex]3.86[/tex] squared inches.
What is area ?Area is the space occupied by any shape.
Area of the square [tex]=side*side[/tex]
We have,

Radius of semi-circle[tex]=3[/tex] inch
Now,
Area of the square [tex]=side*side=6*6=36[/tex] squared inches
Now,
Area of a semi-circle[tex]= \frac{\pi }{2}r^{2}=\frac{22 }{2*7} (3)^2=14.14[/tex] squared inches
So,
Area of two semi-circles[tex]=28.28[/tex] squared inches
Now,
Area of yellow part [tex]= \frac{36-28.28}{2}=3.86[/tex] squared inches
So, Area of yellow part is [tex]3.86[/tex] squared inches find out by dividing by two because other part is equals to yellow part.
