Answer:

p = 39       f = 44    

Step-by-step explanation:

p = $ 1.73

f = $ 1.44

equation

p + f = 83

1.73 p + 1.44 (83 - p) = $ 130.83

p = 39 (amount of times fruit pies were sold).

Therefore,

p = 39

f = 44

The equation that shows the relationship between the variables are T = 0.112N, D = 54A and T = 62.5A

An equation is an expression that shows the relationship between two or more numbers and variables.

Let k represent the constant of proportionality

3) T = kN

28 = 250k

k = 0.112

i) T = 0.112N

ii) T = 0.112(300) = 33.6

iii) 98 = 0.0112N

N = 875

4) D = kA

270 = 5k

k = 54

i) D = 54A

ii) D = 54(4.5) = 243

iii) 324 = 54A

A = 6

5) T = kA

150 = 2.4k

k = 62.5

i) T = 62.5A

ii) T = 62.5(1.8) = 112.5

iii) 3(60) = 62.5A

A = 2.88

The measure of angle x will be 88 degrees. Then the correct option is C.

The complete question is attached below.

Let there is a triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:

2ab cos θ = a² + b² – c²

The triangle is shown below.

Then the value of the variable x will be

2 · 7 · 10 · cos x = 7² + 10² – 12²

       140 · cos x = 49 + 100 – 144

                cos x = (149 – 144) / 140

Answer:

consistent and dependent

consistent and independent

Step-by-step explanation:

If a system of equations has no solutions, it is said to be inconsistent.

If a system of equations has at least one solution, it is said to be consistent.

If there is just one solution to a system of equations, it is said to be independent.

If a system of equations has an unlimited number of solutions, it is dependent.

A 3 x 3 system of equations is a three-variable system of equations. That is correct (x, y, z)

A three-by-three-equation system might be dependent, independent, or inconsistent.

A 3 x 3 system of equations can be written as follows:

consistent and self-sufficient (This indicates that there is just one answer.)

Dependable and consistent (It has infinite solutions)

If it is inconsistent, it can neither be dependent nor independent

The school store is in $42 loss , Option B is the correct answer.

When the sales is more than the expenses then it is called profit and vice versa is called Loss.

The sales and expenses for three months are given

To calculate overall Profit/Loss

Total Expenses = $125 + $0 +$ 57 = $182

Total Sales = $47 +$65 + $28 = $140

Therefore as sales is less than the expense , The school is in loss

Loss = $ 182 -$ 140 = $42

The area of the trapezoid is calculated as 45.5 feet squared.

What does Area of Trapezoid mean?

The entire area occupied by the sides of a trapezoid is its area. It's important to notice that if we know the lengths of all the sides, we can divide the trapezoid into smaller polygons, such as triangles and rectangles, calculate their areas, and then sum them all together to determine the area of the trapezoid.

If the parallel sides of the trapezoid are known, along with their height, it is possible to determine their area. It is expressed as,

A=[tex]1/2[/tex](a+b) h

where, A= the area of the trapezoid

h= height

'a' & 'b' = parallel side bases

a=5.5 feet , b= 8.5 feet & h=6.5 feet

A=[tex]1/2[/tex](a+b)h

∴A=[tex]1/2[/tex](5.5+8.5)*6.5

⇒A=[tex]1/2[/tex](14)*6.5

⇒A=7*6.5

⇒A=45.5 feet squared

Therefore, the solution is  (b) 45.5 feet squared.

Domain is the value that can be an input to the function and the range is all the value a function can obtain.

From the given graphs ,

For Graph 1

It can be seen that the line extends from x = -5 to +4

where -5 is not included

therefore the domain is given by

D = { x| -5 < x ≤4}

and the range is

R = {y | -3 < y≤4}

For Graph 2

The input value x extends from -∞ to +∞

To find the area of the shaded sector, this will be:

The distance between point A and point B is 371 ft if the Mason measures an angle of depression to the boat at point A to be 16°.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

A boat is heading towards a lighthouse, where Mason is watching from a vertical distance of 122 feet above the water. Mason measures an angle of depression to the boat at point A to be 16°.

We can draw the above situation as a form of a right-angle triangle.

From the figure, the distance between AB is x ft

From the right angle triangle DBC:

tan66 = 122/CB

CB = 54.31 ft

From the right angle triangle DAC

tan16 = 122/AC

AC = 425.46 ft

x = AC - CB

x = 425.46 - 54.31

x = 371.15 ft ≈ 371 ft

Thus, the distance between point A and point B is 371 ft if the Mason measures an angle of depression to the boat at point A to be 16°.

1/7 + r = 1/3

Step-by-step explanation:

Rocco takes 7 hours to do the job.
In 1 hour, Rocco does 1/7 of the job.

Rocco's rate is 1/7 job per hour.

It takes Giulia x hours to do the job.

In 1 hour, Giulia does 1/x of the job.

Let r = 1/x. Giulia's rate is r part of the job per hour.

Together, Rocco and Giulia take 3 hours to do the job.

In 1 hour, Rocco and Giulia do 1/3 of the job.

Together, their rate is 1/3 of the job per hour.

1/7 + r = 1/3

The parabola with the minimum at (4, -3) is the third option:

[tex]y = 0.5*x^2 - 4x + 5[/tex]

Remember that for a parabola of the form:

[tex]y = a*x^2 + b*x + c[/tex]

If a > 0, the minimum is at the x-value of the vertex:

[tex]x = \frac{-b}{2a}[/tex]

If a < 0, there is no minimum (so we discard option 2).

Taking the third option:

[tex]y = 0.5*x^2 - 4x + 5[/tex]

The x-value of the vertex is:

[tex]x = \frac{-(-4)}{2*0.5} = 4[/tex]

As expected.

To get the y-value of the vertex (and minimum) we just evaluate the parabola equation in x = 4.

[tex]y = 0.5*(4)^2 - 4*4 + 5 = -3[/tex]

So the minimum is at (4, -3), as expected, so that is the correct option.
