Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

[tex]y=-x^2+64x-292[/tex]

Required

Calculate the maximum amount of profit

A quadratic function is of the form

[tex]y = ax^2 + bx + c[/tex]

and its maximum, y_max is calculated using:

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

So for [tex]y=-x^2+64x-292[/tex]

By comparison with [tex]y = ax^2 + bx + c[/tex]

We have that:

[tex]a = -1[/tex]   [tex]b = 64[/tex]   and [tex]c = -292[/tex]

[tex]y_{max} = \frac{-64}{2*-1}[/tex]

[tex]y_{max} = \frac{-64}{-2}[/tex]

[tex]y_{max} = 32[/tex]

Hence, the maximum amount of profit is 32

Answer:

[tex]21\frac{1}{2} \ or\ 21.5[/tex]

Step-by-step explanation:

Given that:

Initial score of Beth = 0

Round 1 scores:

Points lost = [tex]3\frac{1}{2} = 3.5[/tex]

Round 2 scores:

Points won = [tex]28\frac{1}{2}=28.5[/tex]

Round 3 scores:

Points lost = [tex]3\frac{1}{2} = 3.5[/tex]

To find:

The final score of Beth in the video game = ?

Solution:

Let us calculate the total points lost and total points won by Beth in the video game.

Then we will subtract the total points lost from the total points won to find the final score in the video game.

Total points won = 28.5

Total points lost = 3.5 + 3.5 = 7

So, final score = Total points won - Total points lost

Final score = 28.5 - 7 = 21.5 or [tex]\bold{21\frac{1}{2}}[/tex]

Answer:

c=17/16

Step-by-step explanation:

3/16=c-7/8

find the common denominator

3/16=c-14/16

add 14/16 on both sides to cancel

c=17/16

Answer:

c= 17/16

Step-by-step explanation:

move 7/8 to the right so cancel it out by adding which would add with 3/16 giving 17/16 = c

Answer:

y=−8x+53

Step-by-step explanation:

I think... I'm not sure so I'm sorry if its wrong

Answer: Here is an explanation of how to get the answer.

Step-by-step explanation:

It tells you the slope is -8, so you know your equation will look like this:

y = -8x + b,

where b is the intercept. You also are given a point that is on the line, so that is an x and a y value that are a solution to the equation. You can plug those in and solve for b.

5 = -8(6) + b

53 = b

So, your equation is y = -8x + 53

Answer:

x=10

Step-by-step explanation:

3x+10=6x-20 Set the angles equal to each other b/c they are alt. int. angles.

-3x       -3x Subtract by 3x on both sides to get x by itself

----------------

+10    =3x-20

+20         +20 Add 20 to both sides to get x by itself

---------------------

30    =3x

/3        /3 Divide both sides by 3 to get x by itself

-------------

10    =x

x=10 Write x first.

Answer:

9.833333

Step-by-step explanation:

Answer:

16.8

Step-by-step explanation:

Answer:  If the original equation is y = 3x -4,  the slope is 3.

Any equation of a line parallel to the line y = 3x -4 will have a slope of 3.

Step-by-step explanation:

In slope-intercept form, y =mx + b the coefficient of x, m is the slope.

Here 3 is that value.

It is very unusual to have two equal signs in a question about slope.

I am not sure what to do with the =8y + 1

Is this supposed to be another equation in the system, missing a term?

Answer:

3/4

Step-by-step explanation:

3/4 is one example of a fraction that is greater than 1/2. If 1/2 become 2/4, therefore 3/4 is a fraction which is greater than 1/2.

Answer:

-27.2

Step-by-step explanation:

Answer:

The crew expects their voyage to last 8 days.

Step-by-step explanation:

There are initially 145 lb of food in the sailboat.

The crew plans to eat 15 lb of food per day, and they want to leave 25 lb of food remaining when they end the voyage.

The amount of food to eat during the voyage is 145 - 25 = 120 lb.

Since the daily consumption of food is 15 lb, there is enough food for 120/15 = 8 days.

The crew expects their voyage to last 8 days.

Answer:

(-5,10)

Step-by-step explanation:

You need to do this by finding a point where it is a solution to both equations. You can do this by using systems of equations.

y=25+3x

y=-5-3x

subtracting, you get 0=30+6x

simply, -30=6x, x=-5.

you're half way done! now plug in x in one of the equations to get the y value.

-5*3+25 = y = 10

Answer:

[tex]4.6\ \text{cm}[/tex]

Step-by-step explanation:

Perimeter of the pentagon = 20.5 cm

Length of 4 sides = [tex]x[/tex]

Length of the other side = 2.1 cm

Perimeter of the pentagon will be

[tex]x+x+x+x+2.1=20.5\\\Rightarrow 4x+2.1=20.5\\\Rightarrow 4x=20.5-2.1\\\Rightarrow 4x=18.4\\\Rightarrow x=\dfrac{18.4}{4}\\\Rightarrow x=4.6\ \text{cm}[/tex]

The value of [tex]x[/tex] is [tex]4.6\ \text{cm}[/tex].
