For the first 4 home football games, the
concession stand sold 600 hotdogs. If
that ratio stays constant, how many
hotdogs will sell for all 10 home games?
Answer:
1500
Step-by-step explanation:
600 divided by 4 to see how much hotdogs are sold EACH home football game. This gives you 150 each game so you multiple it by ten in order to get the total for ten home games
solve for c -49 = 2c - 29
Answer:
c = -10
Step-by-step explanation:
Hello!
According to the question we need to solve for c in the equation -49 = 2c - 29
-49 = 2c - 29
Flip the equation
2c - 29 = -49
Add 29 to both sides
2c - 29 + 29 = -49 + 29
2c = -20
Divide both sides by 2 to single out the variable
2c/2 = -20/2
c = -10
So, the value of c is -10
1. f(x) = 3x² + 18x + 32
The zeroes of the equation f(x) is 3x² + 18x + 32 is x = -18 -7.75/ 6 and x = -18 + 7.75/ 6
What is polynomial?Algebraic expressions called polynomials include coefficients and variables. Indeterminates are another name for variables. For polynomial expressions, we can do mathematical operations like addition, subtraction, multiplication, and positive integer exponents but not division by variables.
Given f(x) = 3x² + 18x + 32
3x^2 + 18x + 32 = 0
Here, a = 3
b = 18
c = 32
-b ±[tex]\frac{\sqrt{b^2-4ac} }{2a}[/tex]
-18 ± [tex]\frac{\sqrt{18^2-4(3)(32)} }{2(3)}[/tex]

-18 ± [tex]\frac{\sqrt{-60} }{6}[/tex]
-18 ± [tex]\frac{-7.75}{6}[/tex]
X = -18 (-7.75)/ 6 and x = -18 – (-7.75)/ 6
X = -18 -7.75/ 6 and x = -18 + 7.75/ 6
Therefore, the zeroes of the polynomial are X = -18 -7.75/ 6 and x = -18 + 7.75/ 6

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.
A baseball coach takes her team out for pizza every time they win a game. Not everyone can come each time, so she orders the pizzas based on how many players are coming. After last week's victory, she bought 3 small pizzas and 4 large pizzas, the perfect amount for the 19 players going out for pizza. This week, there were 25 players going, so she ordered 5 small pizzas and 5 large pizzas, which was also just the right amount. How many people does each size of pizza feed?
Each small pizza feeds
people, and each large pizza feeds
people.
1 small pizza and 4 large pizza feeds people according to the system of equations.
Let the number of small pizza be x and the number of large pizza be y.
So, we get the two equations as:
3 x + 4 y = 19 ...(1)
5 x + 5 y = 25 ...(2)
Taking 5 common from equation 2, we get that:
x + y = 5
x = 5 - y
Put it in equation 1, we get that:
15 - 3 y + 4 y = 19
15 + y = 19
y = 4
x = 5 - 4 = 1
Therefore, we get that, 1 small pizza and 4 large pizza feeds people according to the system of equations.

School A started the final round with 87 points. School B started with 45. The game ends with the two schools tied. Let x represent the number of correct answers given by School A in the final round. Write an equation that models the outcome of the contest. Then find the number of answers that each school got correct in the final round.
School A got 14 questions correct and School B got 14 questions correct.
What are the number of correct answers?The first step is to form a linear equations that represent the scores of the schools in the final round. A linear equation is an equation that has a single variable that is raised to the power of one. When graphed, a linear equation is usually a straight line.
Let x represent the number of correct and incorrect answers scored by School A
Total score at the end of the final round = beginning score + total scores of correct answers - total scores of incorrect answers
Total score at the end of the final round for School A :

87 + 12x -3x
87 + 9x
Total score at the end of the final round for School B :

If the two schools are tied, it means that both of the above expressions would be equal

The system of equations has one real solution (2,4).
What is a system of equations?Simultaneous equations or systems of equations are two or more equations in algebra that must be solved simultaneously (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a unique solution.The given system of equations is:
y = x²
y = 2x
Substitute the value of y in the second equation,
x² = 2x
x²- 2x = 0 ( Factorize it)
x(x - 2) = 0
x = 0 and x = 2
Putting the value of x in the equations to obtain the value of y,
y = x² = 0
y = 2x = 2(0) = 0
y = x² = 2² = 4

Given,
The base angle of an isosceles triangle = 40 degrees

Isosceles triangle:
Therefore, an isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and skelos are the source of the name (leg). An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal.
Here,
We know that total interior angle of a triangle is 180°
In an isosceles triangle base angles will be equal.
Here, base angle is 40 degrees.
Now, the top, vertex angle = total angle - base angle × 2

If 3 groups of 4 add up to 12, 12 separated into three equal groups adds up to 4 in each group in division.Each component of a division equation has its own name.Dividend: The dividend is indeed the number divided during the division process.Divisor: The divisor is the number with which the dividend is divided.Quotient: A quotient is an outcome of the division process.Quotient: A quotient is an outcome of the division process. emainder: We can't always divide things exactly. There could be an extra number. The leftover number is known as the remainder.The following explains the connection between these four parts: Dividend = Divisor x Quotient + RemainderFor the given question.
The number of wooden board bought by Madelyn = 7.
The length of all boards = 1.9 meters.
Thus, to find the length of each wooden board, simply divide the total length by the total board as each board is identical.
Each length = total length/number of boards

AB=3x, BC=x+5 and AC=24. what is the midpoint of ac?
IF AB=3x, BC=x+5 and AC=24 then the midpoint of AC is point B.
What does a midpoint mean?Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.
WE have given that AB=3x, BC=x+5 and AC=24. Since B is the midpoint, then we have:
AB = BC = AC/2
Now Substitute and solve for x:
AB = BC
x + 5 = 3x
x + -3x = -5
2x = 5
x = 5/2
AB = 3(5/2) = 15/2
BC = x + 5 = 5/2 + 5 = 15/2

The tree is 79 feet tall if the ground is 79 feet from the tree and the angle of elevation is 45°.
Angle of elevation:
The angle of elevation is an angle that is formed between the horizontal line and the line of sight.
Therefore, the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
Given,
The angle of elevation to a nearby tree from a point on the ground is measured to be 45 degrees.
Here we need to find how tall is the tree if the point on the ground is 79 feet from the tree and we have also need to round the answer to the nearest hundredth of a foot.
Here we know that
The angle of elevation = 45°
Distance of the point from the tree = 79 feet
Suppose h is the height of the tree.
Then the value of h is calculated as,
=> h / 79 = tan 45°
We know that, the value of tan 45° = 1,
So,
=> h/79 = 1
Then the value of h is,
=> h = 79
