Answer:

[tex]P(x) = -0.25x^2 + 42x - 90[/tex]

Step-by-step explanation:

Given

[tex]C(x) = -17x + 90[/tex]

[tex]R(x) =- 0.25x^2 + 25x[/tex]

Required

Determine the profit function.

Profit function is calculated as thus:

[tex]P(x) = R(x) - C(x)[/tex]

So, we have:

[tex]P(x) = -0.25x^2 + 25x -(-17x + 90)[/tex]

[tex]P(x) = -0.25x^2 + 25x + 17x - 90[/tex]

[tex]P(x) = -0.25x^2 + 42x - 90[/tex]

Answer:

13.93

Step-by-step explanation:

Meal = 54.65

Sales tax = 8%

= 8/100 * 54.65 + 54.65

= 0.08 * 54.65 + 54.65

= 4.372 + 54.65

= 59.022

Tip = 18% of the meal and tax

= 18/100 * 59.022 + 59.022

= 0.18 * 59.022 + 59.022

= 10.62396 + 59.022

= 69.64596

Total people in the holcomebe family = 5

Cost of meal per person =

69.64596 / 5

= 13.929192

Approximately 13.93

Answer: x = [tex]\frac{-z - 7}{y}[/tex]

Step-by-step explanation:

Flip the equation

xy + z = −7

Add -z to both sides

xy + z + −z = − 7 + −z

xy = −z − 7

Divide both sides by y

[tex]\frac{xy}{y}[/tex] = [tex]\frac{-z - 7}{y}[/tex]

x = [tex]\frac{-z - 7}{y}[/tex]

x = [tex]\frac{-z - 7}{y}[/tex]

Answer:

3.85

Step-by-step explanation:

46.2/12=3.85

Answer:

3.85 dozens of doughnuts

Step-by-step explanation:

well first of a dozen equals 12

dozen = 12

and if you have 46.2 doughnuts then you would divide that be 12

46.2 / 12 = 3.85

46.2 doughnuts is equal to 3.85 dozens

Answer:

123°

Step-by-step explanation:

A supplementary is an angle where two angles add up to be 180°.We can subtract to find its supplement.

180 - 57 = 123°

Best of Luck!

Answer:

123°

Step-by-step explanation:

The supplementary angle is the other angle that makes both angles a linear pair.

So you would do 180° - 57° to solve your answer, which equals 123°

Hope this helps!

9514 1404 393

Answer:

Step-by-step explanation:

The size of the small squares will be the greatest common divisor (GCD) of the dimensions 24 cm and 32 cm. We know these dimensions can be factored as ...

  24 = 3×8

  32 = 4×8

so the GCD is 8 cm.

The rectangles can be covered with squares that are 8 cm on a side.

__

The dimensions of the painting will be the least common multiple of the rectangle dimensions. That is ...

  LCM(24, 32) = 24×32/GCD(24, 32) = 24×32/8 = 96

The smallest square painting that can be made from these rectangles is 96 cm square.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Number replaces with each corresponding value.

The number on the left is the x, and the number on the right of the colon is y.

Simply replace x and if you get the y, it is a match.

y = 1/2(2) = 1

y = 5(1) = 5

y = 1.5(16) = 16

y = 3(1) = 3

Answer:

x < - 2

Step-by-step explanation:

Step 1:

5x + 7 < 2x + 1           Equation

Step 2:

3x + 7 < 1        Subtract 2x on both sides

Step 3:

3x < - 6         Subtract 7 on both sides

Step 4:

x < - 6 ÷ 3        Divide

Answer:

x < - 2

The solution is: in the expression (5w+3) the value of w is: w = -3/5.

Here, we have,

given that,

the expression is: (5w+3)

now, we have to find the value of w

so, we get,

we can find the value of w by making it equal to 0:

5w+3 = 0

<- subtract 3 from both sides

5w = -3  

<- divide 5 from both sides

5w/5 = -3/5

so, we have,

w = -3/5 is the final answer.

Hence, The solution is: in the expression (5w+3) the value of w is: w = -3/5.

Answer:

[tex]22.91^\circ, 202.91^\circ[/tex]

Step-by-step explanation:

Given that:

[tex]tan\theta=0.4226[/tex]

To find:

The two values of [tex]\theta = ?[/tex]

Solution:

By given equation:

[tex]\theta = tan^{-1}(0.4226)[/tex]

[tex]\theta[/tex] can be equal to [tex]\approx 20.91^\circ[/tex]

Also, we know the property that, [tex]tan\theta[/tex] is positive in the 3rd quadrant.

and following is also true:

[tex]tan\theta = tan(180^\circ+\theta)[/tex]

Therefore, another value possible for [tex]\theta[/tex] can be:

[tex]\theta =180^\circ+22.91\\\Rightarrow \theta \approx 202.91^\circ[/tex]

Therefore, the answer is:

[tex]22.91^\circ, 202.91^\circ[/tex]

Answer:

122 ≤ F ≤ 158

Step-by-step explanation:

First we convert the Celsius temperature to Fahrenheit

Mathematically, the formula to use is as follows;

F = 9/5C + 32

So 50 will be;

F = 9/5(50) + 32 = 90 + 32 = 122

70 will be

F = 9/5(70) + 32 = 126 + 32 = 158

So the inequality will be;

122 ≤ F ≤ 158

Answer: [tex]m[/tex] = −3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−40 − 6[tex]m[/tex] − 1 = 7[tex]m[/tex] − 2

Step 2: Simplify −40 − 6[tex]m[/tex] − 1 to −6[tex]m[/tex] − 41.

−6[tex]m[/tex] − 41 = 7[tex]m[/tex] − 2

Step 3: Add 6[tex]m[/tex] to both sides.

−41 = 7[tex]m[/tex] − 2 + 6[tex]m[/tex]

Step 4: Simplify 7[tex]m[/tex] − 2 + 6[tex]m[/tex] to 13[tex]m[/tex] − 2.

−41 = 13[tex]m[/tex] − 2

Step 5: Add 2 to both sides

−41 + 2 = 13[tex]m[/tex]

Step 6: Simplify −41 + 2 to −39.

−39 = 13[tex]m[/tex]

Step 7: Divide both sides by 13.

−[tex]\frac{39}{13}[/tex] = [tex]m[/tex]

Step 8: Simplify [tex]\frac{39}{13}[/tex] to 3.

−3 = m

Step 9: Switch sides.

[tex]m[/tex] = −3

Answer:

If u divide a number the number will decrease

if u multiply the decimal number it will increase.

when multiplying u move the decimal point to the right

if u r dividing u move the decimal point left

how much u move depends on the number of zeros from the number u are dividing or multiplying

Step-by-step explanation:

Answer:x=4

Step-by-step explanation:

The equations y = -x,y = x², and y = x³ have one y-values for a given x-value thus options (A) ,(C) and (D) will be correct.

There are many different ways to define an equation.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

In the first option y = -x

The value of y will be negative of x thus it will be single for every single x.

In the third option x = x² here for every x there will be a single y thus it will be single for every single x.

In option fourth option y = x³ here for x, y will be one thus it will be single for every single x.

In option (B) x = 4 here y is changing for x = 4 thus here y will not be one.

Hence "The equations y = -x,y = x², and y = x³ have one y-values for a given x-value".
