Explanation:
To know how many hours you will have to work, we need to use the given rate of $4.50 per hour as follows:
[tex]\text{ \$1000}\times\frac{1\text{ hour}}{\text{ \$4.50}}=\frac{1000\times1}{4.5}=\frac{1000}{4.5}=222.22\text{ hours}[/tex]Because 1 hour is equivalent to $4.50.

Given:
Elevation of Vander's home = -108 feet
Elevation of Gali's home is ⅔ of that depth below sea level.
Thus, the elevation of Gali's home is:
⅔ of -108 feet =

We have to find x.
We can use the trigonometric relations to find the value of x.
We know that, for a right triangle, the sine of an angle is equal to the quotient between the opposite side and the hypotenuse.
In this case, the opposite side of the angle is the height of the plane (4 mi) and the hypotenuse is x, so we can write:
[tex]\begin{gathered} \cos (40\degree)=\frac{\text{Opposite}}{\text{Hypotenuse}}=\frac{4}{x} \\ x=\frac{4}{\cos (40\degree)}\approx\frac{4}{0.766}\approx5.22 \end{gathered}[/tex]Answer: the value of x is approximately 5.22 miles.
What is the solution to the equation k - 4 3/4 = 8 1/4?k = 4 1\2k = 12k = 13k = 4
Answers
Answer:
Explanation:
The given equation is
k - 4 3/4 = 8 1/4
The fist step is to convert the mixed number to improper fractions.
4 3/4 = 19/4
8 1/4 = 33/4
Thus, the expression becomes
k - 19/4 = 33/4
Adding 19/4 to both sides, we have
k - 19/4 + 19/4= 33/4 + 19/4
k = 52/4
k = 13

Answers
SOLUTION
Angle C is 133 degrees
From the image , angle c is the same as angle a, reason been that they are vertically opposite angles and they are always equal.. let us call angle c and a = x
Angle b = 47 degrees, because they are both vertically opposite angles, and they are always equal.
Angle c + angle a + angle b + 47 = 360 ( sum of angles at a point)
x + x + 47 + 47 = 360
2x + 94 =360
2x = 360-94
2x =266
x= 266/2
x=133 degrees
So angle C is 133 degrees

the function is shaped like a u what is the standard form or basic function.
Answers
The function shaped like a U is in the form of a basic quadratic equation and is represented as a parabola.
The graph of a quadratic function is a U-shaped curve called a parabola. An important feature of graphs is that they have extreme points called vertices.
When the parabola opens upwards, the vertex represents the lowest point of the graph, or the minimum value of the quadratic function. When the parabola opens downwards, the vertex represents the highest point or maximum of the graph.
In both cases, the vertex is the inflection point of the graph. Graphs are also symmetrical about a vertical line through the vertices called the axis of symmetry.
The standard form or basic function for a parabola will be in the form of a quadratic function such as -
[tex]f(x)=a(x-h)^{2} +k[/tex]
where, [tex](h,k)[/tex] = vertex
Thus, the function shaped like a U is in the form of a basic quadratic equation and is represented as a parabola.

Let x be the first integer.
Let y be the second integer.
Let z be the third interger.
The sum of three integers is 244.
[tex]x+y+z=244[/tex]The sum of the first and second integers exceeds the third by 48.
[tex]x+y=z+48[/tex]The third integer is 36 less than the first.
[tex]z=x-36[/tex]Substitute z=x-36 in the equation x+y=z-48 .
[tex]x+y=x-36+48[/tex][tex]x+y=x+12[/tex]Subtract x from both sides of the equation.
[tex]x+y-x=x+12-x[/tex][tex]y=12[/tex]Substitute z=x-36 and y=12 in the equation x+y+z=244.
[tex]x+12+x-36=244[/tex]Add 24 to both sides of the equation.
[tex]2x-24+24=244+24[/tex][tex]2x=268[/tex]Divide both sides by 2.
