Answers
You are running the concession stand for the basketball game. You sell hot dogs for $1.50 and drinks for $2.
a) an equation in a standard form that models this situation is
1.5H + 2D = 250
b) Hot dogs sold 104
What is the equation?Generally, a) Let H be the number of hot dogs sold and D be the number of drinks sold. The equation that models this situation is:
1.5H + 2D = 250
b) To find the number of hot dogs sold, we can solve the equation for H:
1.5H = 250 - 2D H = (250 - 2D) / 1.5
Substituting D = 47 into this equation gives us:
H = (250 - 2*47) / 1.5 H = (250 - 94) / 1.5 H = 156 / 1.5 H = 104
Therefore, you sold 104 hot dogs.

X - 9 = 0
You add 9 on each side
X = 0 + 9
X = 9
Basically, all you're doing is the reverse, you start with 0 and do the opposite of taking away 9 which is adding nine so that you get the number:

A right triangle has a hypotenuse of 10cm. If one angle is 40°, find the length of each leg. Round to the nearest whole number. Enter the smallest leg first. Do not enter units of measurement, only numbers.
Answers
Answer: 6 and 8
Step-by-step explanation: A right triangle is a triangle with one angle that measures 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. In this case, the hypotenuse is 10cm long.
If one angle of the triangle is 40 degrees, then the other angle must be 90-40 = 50 degrees. The remaining two angles of a triangle must add up to 180 degrees, so the third angle is 180-40-50 = 90 degrees. This means that the triangle is a right triangle, and we can use the Pythagorean theorem to find the lengths of the legs.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. In this case, we have a2 + b2 = c2, where a and b are the lengths of the legs and c is the length of the hypotenuse.
Substituting the values from the problem, we have a2 + b2 = 102, which simplifies to a2 + b2 = 100. Since we don't know the values of a and b, we can't solve for them directly. However, we can use the fact that the angle opposite the longer leg is 50 degrees, and the angle opposite the shorter leg is 40 degrees. This means that the longer leg is the opposite side of the 50-degree angle, and the shorter leg is the opposite side of the 40-degree angle.
Since the longer leg is opposite the 50-degree angle, and the shorter leg is opposite the 40-degree angle, we can use the tangent function to find the ratio of the lengths of the legs. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side, so we have tangent(50 degrees) = opposite side / adjacent side = a / b, and tangent(40 degrees) = opposite side / adjacent side = b / a.
Solving for a and b, we have a = b * tangent(50 degrees) and b = a * tangent(40 degrees). Since the legs are the opposite sides of the 40- and 50-degree angles, we can substitute the values from the problem to get a = b * tangent(50 degrees) = 100 * tangent(50 degrees) and b = a * tangent(40 degrees) = 100 * tangent(40 degrees).
To find the values of tangent(50 degrees) and tangent(40 degrees), we can use a calculator or look up the values in a table of trigonometric functions. We find that tangent(50 degrees) = 1.191753592594, and tangent(40 degrees) = 0.839099631177. Substituting these values into the equations for a and b, we have a = 100 * 1.191753592594 = 119.1753592594 and b = 100 * 0.839099631177 = 83.9099631177.
Rounding to the nearest whole number, we have a = 119 and b = 84. The lengths of the legs of the triangle are therefore 6 and 8.

In vertex form the equation of the parabola is [tex]y = -2(x+2)^{2} -5[/tex].
What is Vertex form if Parabola ?
When a graph crosses its symmetry axes, the vertex formula in mathematics may be used to get the vertex coordinate of a parabola. The vertex point is often represented by (h, k). We are aware that a parabola's conventional equation is y=ax2+bx+c. The vertex in this case should be near the base of the U-shaped curve if the coefficient of x2 is positive. The vertex should be at the peak of the U-shaped curve if the coefficient of x2 is negative. The standard form and vertex form of a parabola, as well as the vertex formula, will be covered in this article.
We are aware that the parabola's conventional form is y=ax2+bx+c.
So, y = a(x-h)2 + k is the vertex form of a parabola.
To determine a parabola's vertex, use the vertex formula. There are two methods for locating a parabola's vertex.
Vertex, (h, k) = (-b/2a, -D/4a)
Equation of the parabola,
y = [tex]-2x^{2} - 8x -13[/tex]
here ,
a = -2 , b = -8 and c = -13.
Therefore,
h = -b/2a = +8/-4 = -2 and,
k = -D/ 4a = [tex]-(b^{2} - 4ac)/4a[/tex] = -(64 - 104)/-8 = -40/8 = -5
So, the coordinate of vertex is (-2, -5)
So the vertex form of equation of parabola is
[tex]y = a(x-h)^{2} + k[/tex]
⇒ [tex]y = a(x+2)^{2} -5[/tex]
⇒ [tex]y = ax^{2} + 4ax +4a -5[/tex]
Equating this equation with equation pf parabola we get a = -2
So, in vertex form the equation of the parabola is [tex]y = -2(x+2)^{2} -5[/tex].

To determine the point and slope from the given equation, we can rewrite the equation in the standard form of a linear equation: y = mx + b, where m is the slope and b is the y-intercept (the point at which the line crosses the y-axis).
In this case, the equation is already in the standard form, so we can immediately see that the slope is -5 and the y-intercept is (0, 4). This means that the point at which the line crosses the y-axis is (0, 4), and the slope of the line is -5.

Answers
The height of the candy cane is 11.4024 feet when the man is looking at the top of the candy cane at an angle of 35°.
We have the following information:
A 3 foot Gingerbread man is standing 12 feet from the base of the tall candy cane he has ever seen. He is looking at the top of the candy cane at an angle of 35⁰.
Now, we can find the height of the candy cane using the trigonometric function of tan.
Now, the base will be 12 feet and the height of the candy cane will be added to 3 feet to find the real height of the cane.
Tan 35 = height of the cane/base
0.7002 = Height of the cane/12
Height of the cane = 12*0.7002
Height of the cane = 8.4024 feet
Real height of the cane = 3+8.4024 feet
Real height = 11.4024 feet
Hence, the candy cane is 11.4024 feet when the man is looking at the top of the candy cane at an angle of 35°.

A linear regression equation that represents the data set is y = -29.97x + 1048.80. Also, the number of new cases for 2026 is equal to 689 cases.
How to write the linear regression equation?In this scenario, the Year since 2014 (x) would be plotted on the x-axis of the scatterplot while the New cases (y) would be plotted on the x-axis of the scatterplot.
On the Excel sheet, you should right click on any data point on the scatterplot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.
By critically observing the scatterplot (see attachment) which models the relationship given in the table, an equation for the linear regression is given by:
y = -29.97x + 1048.80
For 2026, the value of x is given by:
x = 2026 - 2014 = 12 years.
Now, we can determine the new cases for 2026:
y = -29.97(12) + 1048.80
y = -359.64 + 1048.80
y = 689.16 ≈ 689 cases.
