What is the answer for 5x1+2?
I

Answer:

8 interior angles

Step-by-step explanation:

Answer:

C. 60

Step-by-step explanation:

You can take away 120 instantly because that angle is acute. This leaves you with A, B, and C. It's most certainly too big to be C. By this point you can look at it and draw a 90 degree angle in your mind and you can see that it looks about 2/3 of a 90 degree angle.

9514 1404 393

Answer:

  110 units

Step-by-step explanation:

Fill in the given value and solve for x.

  c = x^2 -10x +35

  11035 = x^2 -10x +35

  11025 = x^2 -10x +25 = (x -5)^2 . . . . subtract 10 to complete the square

  x = 5 +√11025 = 5 +105 . . . . find the positive solution

  x = 110

The number of units manufactured at a cost of 11,035 is 110 units.

Option D is correct, the region above of the line y=x/2-3 that we can write as  y>x/2-3

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

We know by reading the exercise that the company estimates same day delivery as a region of the miles.

y>x/2-3

We need to represent this region in a graph.

One way is to find the graph of y=x/2-3

This line will divide the plane into two regions. Then, using any point that verifies the original equation  we can find the graph.

y=x/2-3

If x=0

y=-3

The point (0, -3)  is the interception of the line with y-axis.

Now if y=0

0=x/2-3

3=x/2

6=x

The point (6, 0) is the interception of the line with x-axis.

We know that  y>x/2-3 will be the region above of or below of the line y=x/2-3

Now using an arbitrary point (0,0), for example  and replacing in the expression :

0>-3

The point  (0, 0) verifies the expression. Therefore, this point belongs to the region.

Finally, we conclude that the region is the region above of the line y=x/2-3 that we can write as  y>x/2-3 and the correct option is D.

Hence , option D is correct, the region above of the line y=x/2-3 that we can write as  y>x/2-3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

given data

total ounces=500,000

cost per ounce= $460

total amount of the ounce= 500,000*460= $230000000

Time t=3years

rate= 5.17%= 0.0517

Step two:

The inflation we have a compounding effect on the amount

$230000000

A=P(1+r)^t

A=230000000(1+0.0517)^3

A=230000000(1.0517)^3

A=230000000*1.1632

A=$267,536,000

They will receive a total of  $267,536,000

Answer:

1) Let's suppose that you go in a straight line, in a car that moves at a constant speed of 80km/h.

Then the distance from your house (assuming that you start the drive in your house) can be modeled with a linear equation:

D(t) = 80km/h*t

where t is time in hours.

This will be a linear function.

2) Suppose that you have a population of some animal, that grows by 2% each month, and initially, there are 100 individuals of that animal.

Then the first month, the population is 100.

The second month the population increased by a 2%, then it will be:

100 + 100*0.02 = 100*(1.02)

The third month, the population will be 100*(1.02) + 0.2*100*(1.02) = 100*(1.02)^2.

and so on, this is an exponential relation, where the population as a function of the number of months, can be written as:

P(m) = 100*(1.02)^(m - 1)

3) Suppose that you have $100 saved, and each month you can save another $80, let's find a function that says the amount of money that you have saved as a function of the number of months. S(m)

The month number zero (before you started saving) you had $100 saved.

S(0) = $100.

One month after, you have saved $80 more, then you have:

S(1) = $100 + $80

Another month after, you have:

S(2) = $100 + $80 + $80 = $100 + 2*$80

And so on, you already can see the pattern, after m months, you will have:

S(m) = $100 + m*$80 saved.

Answer:

The measure of F is C)60

Step-by-step explanation:

YOu have to subtract 116 from 180 an you should get 64. SO 64 is the other angle inside of the trianlge. You add 64 and 56, you get the answer 120. You subtract 120 from 180 and you get the answer 60. The measure of angle F is 60.

Answer:

Step-by-step explanation:

There are three rules in mathematics that help us solve this problem:

So, we have that the angle opposite the vertex to the angle that measures 116 ° must measure the same: 116 °

So, we have two angles of 116°, so we add, 116 + 116 = 232

360 - 232 = 128

The other two opposite angles (of which one is an internal angle of the triangle) add up to 128

Since they are opposite by the vertex, they measure the same, so we divide by two and it gives us the value of each one:

128/2 = 64

So, if we know by the second rule, 64 + 56 + f = 180

We resolve:

120 + f = 180

(120 + f) - 120 = 180 -120

f = 60

Debbie runs 9 feet per second: 9 ft/s

Jessica runs 1 mile  in 440 seconds: 414/50 ft/s = 207/25 ft/s = 8 7/25 ft/s

jesssica runs 131 feet in 10 seconds: since 1 mile = 5280 ft we have 1/470 mi/s = 5280/470 ft/s = 528/47 ft/s = 11 11/47 ft/s

ron runs 603 feet in 1 minute: 547 ft/min = 603/60 ft/s = 201/20 ft/s = 10 1/20 ft/s

Since:

11 11/47 > 10 1/20 > 9 > 8 7/25

Emily runs the fastest.

Let the figure number be x.

Then the equation will be:

3x

There will be 3x circles in the figure number x.

So, number of circles in 50th figure will be

= 3(50)

= 3 × 50

= 150 circles

The number of circles in the 50th figure is 150 circles.

A sequence in mathematics is a ordered set of objects or numbers which are related with something.

For example, 1, 3, 5, ..... is a sequence of odd numbers.

Here a pattern is shown in the form of the circles.

In the Figure 1, there are 3 circles.

In the figure 2, there are 6 circles.

In the figure 3, there are 9 circles.

It is clear that the pattern is in such a way that 3 circles are increasing to each succeeding figure.

So for the nth figure,

Number of circles will be 3n.

So for 50th figure, number of circles = 3 × 50 = 150 circles

Hence the number of circles in the 50th figure is 150.

Answer:

Step-by-step explanation:

If MQ also bisects angle ∠LMP, then;

<LMQ + <QMP = <LMP

Also <LMQ = <QMP

The equation becomes <QMP + <QMP = <LMP

2<QMP = <LMP

Let <LMP be 8x+40° (This is an assumed value)

2(5x+10) = 8x+40

Open the parenthesis

10x+20 = 8x+40

10x-8x = 40-20

2x = 20

x = 20/2

x = 10

Find <QMP

Since <QMP = 5x+10

<QMP = 5(10)+10

<QMP = 50+10

<QMP = 60 degrees

Note that the angle <LMP was assumed. Any other function can be used depending on the question

[tex] sin(\angle FDE) = 0.3846 [/tex]

Answer:

[tex]r = \±\sqrt{14[/tex]

[tex]Product = -14[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2x} = \frac{r - x}{7}[/tex]

Required

Find all product of real values that satisfy the equation

[tex]\frac{1}{2x} = \frac{r - x}{7}[/tex]

Cross multiply:

[tex]2x(r - x) = 7 * 1[/tex]

[tex]2xr - 2x^2 = 7[/tex]

Subtract 7 from both sides

[tex]2xr - 2x^2 -7= 7 -7[/tex]

[tex]2xr - 2x^2 -7= 0[/tex]

Reorder

[tex]- 2x^2+ 2xr -7= 0[/tex]

Multiply through by -1

[tex]2x^2 - 2xr +7= 0[/tex]

The above represents a quadratic equation and as such could take either of the following conditions.

(1) No real roots:

This possibility does not apply in this case as such, would not be considered.

(2) One real root

This is true if

[tex]b^2 - 4ac = 0[/tex]

For a quadratic equation

[tex]ax^2 + bx + c = 0[/tex]

By comparison with [tex]2x^2 - 2xr +7= 0[/tex]

[tex]a = 2[/tex]

[tex]b = -2r[/tex]

[tex]c =7[/tex]

Substitute these values in [tex]b^2 - 4ac = 0[/tex]

[tex](-2r)^2 - 4 * 2 * 7 = 0[/tex]

[tex]4r^2 - 56 = 0[/tex]

Add 56 to both sides

[tex]4r^2 - 56 + 56= 0 + 56[/tex]

[tex]4r^2 = 56[/tex]

Divide through by 4

[tex]r^2 = 14[/tex]

Take square roots

[tex]\sqrt{r^2} = \±\sqrt{14[/tex]

[tex]r = \±\sqrt{14[/tex]

Hence, the possible values of r are:

[tex]\sqrt{14[/tex] or [tex]-\sqrt{14[/tex]

and the product is:

[tex]Product = \sqrt{14} * -\sqrt{14}[/tex]

[tex]Product = -14[/tex]

Answer:

78.4

Step-by-step explanation:

You add them all up and divide by however many numbers there are.

Answer:

78.4

Step-by-step explanation:

To find the mean of something, you need to add all the values together, then divide the sum by the number of numbers there are.

The sum of all the numbers is 784, and there are 10 numbers.

So, the equation you need to solve is:

784 / 10 = ?

This equals 78.4, so the mean is 78.4.

Answer:

120 mL of 10% HCL will be used.

Step-by-step explanation:

to solve this, we have to generate an equation for the mixture, to get the volume of 10% HCl needed.

Let the volume needed = x

5% of x + (20% of 60ml) = 10% of ( 60 + x) ml of new mixture

0.05x + (0.2 × 60) = 0.1 × (60 + x)

0.05x + 12 = 6 + 0.1x

12 - 6 = 0.1x - 0.05x

6 = 0.05x

x = 6 ÷ 0.05

x = 120

Therefore, 120 mL of 10% HCL will be used.
