Answer:

$97.24

Step-by-step explanation:

You can use a direct proportion.

175 is to $52.36 as 325 minutes is to x.

Use two ratios of minutes/dollars:  

175/52.36 = 325/x

Cross multiply.

175x = 52.36 * 325

175x = 17,017

x = 17,017/175

x = 97.24

Answer: 500 dollars

You just plug in 100 to the x’s in the equation

The company's profit be if 100 games are sold is $41100

The profit function is given as:

[tex]p(x) = -0.3x^2 + 45x - 1000[/tex]

When the number of games is 100, it means that

x = 100

So, we substitute 100 for x in the profit function

[tex]p(x) = -0.3x^2 + 45x - 1000[/tex] becomes

[tex]p(100) = -0.3(100)^2 + 45(100) - 1000[/tex]

Evaluate the exponents

[tex]p(100) = -0.3(10000) + 45(100) - 1000[/tex]

Open all brackets

[tex]p(100) = -3000 + 45100 - 1000[/tex]

Evaluate like terms

[tex]p(100) = 41100[/tex]

Hence, the company's profit be if 100 games are sold is $41100

Answer:

[tex]2.5[/tex]

Step-by-step explanation:

The given radical expression is

[tex](2+\sqrt{-\frac{3}{2} }) (2-\sqrt{-\frac{3}{2} })[/tex]

Observe that, the given expression can be written as difference of two squares.

That is; [tex](x+y)(x-y)=x^2-y^2[/tex]

We apply this property to obtain:

[tex](2+\sqrt{-\frac{3}{2} }) (2-\sqrt{-\frac{3}{2} })=2^2-(\sqrt{-\frac{3}{2} })^2[/tex]

We now simplify to get:

[tex](2+\sqrt{-\frac{3}{2} }) (2-\sqrt{-\frac{3}{2} })=4-\frac{3}{2}[/tex]

This simplifies to:

[tex](2+\sqrt{-\frac{3}{2} }) (2-\sqrt{-\frac{3}{2} })=\frac{5}{2}=2.5[/tex]

Answer:

6 minutes

Step-by-step explanation:

There are two ways you can simplify this problem:

1. change the dimensions to 3 dm × 3 dm × 5 dm, because 1 L = 1 dm³

2. Adjust the 5 dm dimension to 4/5 that value: 4 dm. Then you're filling a whole volume that is 3 dm × 3 dm × 4 dm = 36 dm³ = 36 L.

__

At the rate of 6 L/min, the tank will be filled to the desired level in ...

(36 L)/(6 L/min) = 6 min . . . . and 0 seconds

_____

A decimeter is 0.1 m = 10 cm, so 1 cubic decimeter is (10 cm)³ = 1000 cm³ = 1 liter. Using decimeters as the unit of measure in volume problems can make conversion to liters trivial.

Answer: The system of equations has no solutions.

Step-by-step explanation:

Identify the equation as:

[tex]x + 2y - z=3[/tex]   [Equation 1]

[tex]2x -y + 2z=6[/tex]    [Equation 2]

[tex]x - 3y + 3z=4[/tex]    [Equation 3]

Multiply  [Equation 1]  by -2 and add this to [Equation 2] :

[tex](-2)(x + 2y - z)=3(-2)[/tex]

[tex]\left \{ {{-2x - 4y +2z=-6} \atop {2x -y + 2z=6}} \right.\\ ..........................\\-5y+4z=0[/tex]

 Find another equation of two variables: Multiply  [Equation 3]  by -2 and add this to [Equation 2]:

[tex](-2)(x - 3y + 3z)=4(-2)[/tex]  

[tex]\left \{ {{2x -y + 2z=6} \atop {-2x +6y -6z=-8}} \right.\\........................\\5y-4z=-2[/tex]

Then you get this new system of equations. When you add them, you get:

[tex]\left \{ {{-5y+4z=0} \atop {5y-4z=-2}} \right.\\..................\\0=-2[/tex]

Since the obtained is not possible, the system of equations has no solutions.

The solution to the system of equations x + 2y - z = 3, 2x - y + 2z = 6, and x - 3y + 3z = 4 is (-1, 1, 2) utilizing substitution method.

The subject of this question is to find a solution to the system of linear equations. We can solve this system by methods of either substitution, elimination or matrix - but let's use substitution. First, let's isolate x in the first equation: x = 3 - 2y + z. Then we substitute x into the second and the third equation:

After simplifying these equations, we find y = 1 and z = 2. Plugging these back into x = 3 - 2y + z, we get x = -1. Therefore, the solution to the system is (-1, 1, 2).

X^2-4x+4 is the answer, to save you points next time, use an app called M8thw8y

First you want to drop the parenthesis. If there is a “+” sign, you do not have to change anything. If there is a “-“ sign, you have to distribute the negative in order to simplify, so imagine you are distributing -1 to 7x + 3 to make it -7x -3.

So, you now have x^2 + 3x - 4 + 16 -5 - 7x -3. (I evaluated the 4^2 to 16)

Now, what you want to do now is to combine like terms. Notice that there is only one x^2, so it is the same. There are two terms that have “x”. 3x and -7x react like normal numbers and they form -4x. The numbers who don’t have x on them you combine like terms.

Answer is x^2 - 4x - 12

Answer:

2. The correct answer option is 25%.

3. The experimental probability is 3% greater than the theoretical probability.

Step-by-step explanation:

2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.

We are to find the experimental probability of getting the number 2.

P (2) = [tex]\frac{5}{20} \times 100 =\frac{1}{4} \times 100[/tex] = 25%

3. The theoretical Outcomes are: HH HT TH TT

So theoretical probability of getting HH = [tex]\frac{1}{4} \times 100[/tex] = 25%

Total number of outcomes = [tex]28+22+34+16[/tex] = 100

So experimental probability of getting HH = [tex]\frac{28}{100} \times 100[/tex] = 28%

Therefore, the experimental probability is 3% greater than the theoretical probability.

Answer:

65°, 70°, 80°, 155°, 170°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 ( pentagon )

sum = 180° × 3 = 540°

Sum the given angles and equate to 540

x + x - 5 + x + 10 + 2x + 15 + 2x + 30 = 540

7x + 50 = 540 ( subtract 50 from both sides )

7x = 490 ( divide both sides by 7 )

x = 70

Hence angles are

x = 70°

x - 5 = 70 - 5 = 65°

x + 10 = 7 0 + 10 = 80°

2x + 15 = (2 × 70) + 15 = 140 + 15 = 155°

2x + 30 = (2 × 70) + 30 = 140 + 30 = 170°

Answer:

Part A) The equation that represent the situation is [tex]\frac{n+54}{9}=21[/tex]

Part B) The value of n is [tex]n=135[/tex]

Part C) The equation is [tex]35+n=60[/tex] and the solution is [tex]n=25[/tex]

Step-by-step explanation:

Part A) A number is increased by 54. The sum is then divided by 9. The result is 21.  Write an equation to represent the description above. Use n for the number

Let

n-----> the number

we know that

The linear equation that represent this situation is equal to

[tex]\frac{n+54}{9}=21[/tex]

Part B) Find the value of n

we have

[tex]\frac{n+54}{9}=21[/tex]

solve for n

Multiply by 9 both sides

[tex]n+54=21*9[/tex]

[tex]n+54=189[/tex]

Subtract 54 both sides

[tex]n=189-54[/tex]

[tex]n=135[/tex]

Part C) Choose two numbers and use them to do the following:

Write an equation that shows your first number added to n equal to your second number. Solve your equation for n

I choose 35 and 60

[tex]35+n=60[/tex]

Solve for n

Subtract 35 both sides

[tex]n=60-35[/tex]

[tex]n=25[/tex]

Answer:

The probability that the candy picked is not grape flavored would be 4/5

Step-by-step explanation:

We are given that a bag contains 10 pieces of flavored candy. 4 lemon, 3 strawberry, 2 grape and 1 cherry. The probability that the candy picked is not grape flavored is calculated as;

(number of candy that are not grape flavored)/ ( total number of candy in the bag)

= (4+3+1)/(10)

= 8/10

=4/5

Therefore, the probability that the candy picked is not grape flavored would be 4/5

To find the probability that a randomly picked candy is not grape flavored, we will follow these steps:

1. Count the total number of pieces of candy in the bag. This is the sum of all the different flavors of candy:
  - 4 lemon candies
  - 3 strawberry candies
  - 2 grape candies
  - 1 cherry candy
  The total number is 4 + 3 + 2 + 1 = 10 candies.

2. Count the number of candies that are not grape flavored. Since there are 2 grape candies, the number of candies not grape flavored is the total minus the grape candies:
  10 (total candies) - 2 (grape candies) = 8 candies that are not grape flavored.

3. Calculate the probability of picking a non-grape flavored candy. Probability is the number of favorable outcomes divided by the total number of possible outcomes. In our case, the favorable outcomes are the instances where we pick a non-grape flavored candy, and the total possible outcomes are picking any candy from the bag:
  Probability (not grape flavored) = Number of non-grape flavored candies / Total number of candies
  Probability (not grape flavored) = 8 / 10

4. Simplify the fraction, if needed. In this case, the fraction 8/10 can be simplified to 4/5 by dividing both the numerator and denominator by the greatest common divisor, which is 2.

Therefore, the probability of picking a candy that is not grape flavored from the bag is 4/5, or 80% if expressed as a percentage.

Answer:

John will get more money after 5 years.

Step-by-step explanation:

To calculate compound interest we use the formula

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

A = Amount

P = Principal

r = Rate of interest ( in decimal )

n = number of compounding period (quarterly = 4) (monthly = 12)

t = time in years

John wants to deposit $1000 with an interest of 4% compounded quarterly for 5 years.

[tex]A=1,000(1+\frac{0.04}{4})^{(4)(5)}[/tex]

[tex]A=1,000(1.01)^{20}[/tex]

A = 1000 ( 1.22019 )

A = $1220.19

John will get $220.19 as interest after 5 years.

Cayden wants to deposit $1,000 with an interest of 3% compounded monthly for 5 years.

[tex]A=1,000(1+\frac{0.03}{12})^{(12)(5)}[/tex]

[tex]A=1,000(1.0025)^{60}[/tex]

A = 1,000 ( 1.161617 )

A = 1161.62

Cayden will get $161.62 as interest after 5 years.

Therefore, John will get more money after 5 years.

Answer:

Step-by-step explanation:

Recall that an equilateral triangle has three equal interior angles, all 60°.  Let b represent the length of the base.  Draw a dashed line from the upper vertex to the base, perpendicularly.  This dashed line represents the height or altitude of the triangle.  

Now construct a triangle whose opposite side is this altitude, whose hypotenuse is b (and whose base is (1/2)b).

The altitude (opp) is then given by sin Ф = opp / hyp = opp / b.  Solving this for the altitude (opp), we get b·sin 60°:

alt (opp)       √3

------------- = ------

  hyp             2

                                                b·√3    

so that 2 alt = b·√3, or alt = ------------

                                                    2

Thus, for any equilateral triangle of side length b, the height of the triangle is

                             √3

alt = height = b · ------

                               2

Please note:  Your problem statement refers to "the equilateral triangle below."  It's important that you share such illustrations, along with all instructions.  In this case your question was general enough so that I could use the definitions of "sine," "equilateral," etc., to come up with a general answer.

Step-by-step explanation:

[tex]f(x) = 6x^2 + 12x - 7[/tex]

To find out the zeros of the quadratic function, we apply quadratic formula

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

From the given f(x), the value of a=6, b=12, c=-7

Plug in all the values in the formula

[tex]x=\frac{-12+-\sqrt{12^2-4(6)(-7)}}{2(6)}[/tex]

[tex]x=\frac{-12+-\sqrt{312}}{2(6)}[/tex]

[tex]x=\frac{-12+-2\sqrt{78}}{2(6)}[/tex]

Now divide each term by 12

[tex]x=-1+-\frac{\sqrt{78} }{6}[/tex]

We will get two values for x

[tex]x=-1+\frac{\sqrt{78} }{6}[/tex] and

[tex]x=-1-\frac{\sqrt{78} }{6}[/tex]
