Step-by-step explanation:

it depends on if you are adding A and B  it would be P= 0.7 and if you are multiplying it would be P= 0.12

Yes, SSS

PR are already a given side. PS and PQ are also given sides. Lastly, RS and RQ are given sides.

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:

Step-by-step explanation:

3x²+48x-12=0

divide everithing by 3

x²+16x-4 =0

(a+b)² = a²+ 2ab+ b²

so a=1, 2ab=2*1*b=2b=16 =2*8 therefore b=8

(x+8)²-4 -64 = 0 (make sure you take away the b²=64)

(x+8)² = 68

√(x+8)² = √68

x+8 = ±2√17

x= -8±2√17

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:

thats easy just.......

Step-by-step explanation:

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:

C. x=30

Step-by-step explanation:

Simply both sides of the equation

8x−3(2x−4)=3(x−6)

8x+(−3)(2x)+(−3)(−4)=(3)(x)+(3)(−6)(Distribute)

8x+−6x+12=3x+−18

(8x+−6x)+(12)=3x−18(Combine Like Terms)

2x+12=3x−18

2x+12=3x−18

Step 2: Subtract 3x from both sides.

2x+12−3x=3x−18−3x

−x+12=−18

Step 3: Subtract 12 from both sides.

−x+12−12=−18−12

−x=−30

Step 4: Divide both sides by -1.

[tex]\frac{-x}{-1} =\frac{-30}{-1}[/tex]

x=30

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].

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:

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:

Step-by-step explanation:

To find f(x), you can replace x in the given function with (x/5).

  f(5(x/5)) = (x/5 -5)/(5(x/5) -1)

  f(x) = (x/5 -5)/(x -1)

  f(x) = (x -25)/(5(x -1))

  f(x) = (x -25)/(5x -5)

The only domain restriction is that x cannot make the denominator zero:

  x cannot be 1. (The domain is all real numbers except 1.)

Answer:

-1

Step-by-step explanation:

1. A water wheel rung’s height as a function of time can be modeled by the equation:

h - 8 = -9 sin6t

(b) Determine the maximum height above the water for a rung.

Given the rung's height modeled by the equation;

h - 8 = -9 sin6t

h(t) = -9sin6t + 8

At maximum height, the velocity of the rung is zero;

dh/dt = 0

dh/dt = -54cos6t

-54cos6t = 0

cos6t = 0/-54

cos6t = 0

6t = cos^-1(0)

6t = 90

t = 90/6

t= 15

Substitute t = 15 into the expression to get the maximum height;

Recall:

h(t) = -9sin6t + 8

h(15) = -9sin6(15) + 8

h(15) = -9sin90 + 8

h(15) = -9(1)+8

h(15) = -9+8

h(15) = -1

hence the maximum height above the water is -1

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]
