Answer:

what is the period after the 9?

Answer:

50

Step-by-step explanation:

Evaluate the products before addition

18 - (9 × - [tex]\frac{4}{3}[/tex] ) + (10 × 2)

= 18 - (- 12) + 20

= 18 + 12 + 20

= 50

Answer:

x = 30

Step-by-step explanation:

The sum of the 3 interior angles of a triangle = 180°, hence

x + x + 10 + 3x + 20 = 180

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

Answer:

C. 0.36

Step-by-step explanation:

There is already a 45% chance of having oil on the land.

The oil kit has an 80% accuracy rate.

Therefore the kit has an 80% chance, of that 45% chance, of detecting oil. (Assume the owners in the area are correct in their 45% assumption)

This can be expressed as 80%*40% or 0.8*0.45

= 0.36 or 36%

Hope this helps!

Answer:

C. [tex]\{y|y\ge 1\}.[/tex]

Step-by-step explanation:

Consider the parent function [tex]f(x)=\sqrt{x}.[/tex]

Now consider given function [tex]h(x)=\sqrt{x+4}+1[/tex] (translated 4 units left and 1 unit up.)

Answer:

The range of the function h(x) is [tex]R=\{y|y\geq 1\}[/tex]

Step-by-step explanation:

Given : The graph of [tex]y=\sqrt{x}[/tex] is translated 4 units left and 1 unit up to create the function h(x).

To find : What is the range of h(x)?

Solution :

When the graph f(x) is translated then

1) f(x)+b shifts the function b units upward.

2) f(x + b) shifts the function b units to the left.

The graph of [tex]y=\sqrt{x}[/tex] is translated 4 units left.

i.e. [tex]y=\sqrt{x+4}[/tex]

The graph of [tex]y=\sqrt{x}[/tex] is translated 1 unit up.

i.e. [tex]y=\sqrt{x+4}+1[/tex]

So, The required function h(x) is [tex]h(x)=\sqrt{x+4}+1[/tex]

The range of a function is set of output values produce by a function.

In the given graph, y value is always greater than and equal to 1.

So, The range of the function h(x) is [tex]R=\{y|y\geq 1\}[/tex]

Answer:

(x-2)/3 = g

Step-by-step explanation:

First you move the 2 over to the same side as the x by subtracting it on both side, because you are trying to make the g "alone". Then you move the 3 by doing the inverse, just like with the 2. Since you are multiplying 3 on one side to move to the other side you have to divide both sides by 3.

Answer:

g= (x-2)/3

Step-by-step explanation:

x=3g+2

Subtract 2 from each side

x-2=3g+2-2

x-2 = 3g

Divide each side by 3

(x-2)/3 = 3g/3

(x-2)/3 =g

g= (x-2)/3

Answer: Blueberry = $6, Pumpkin = $17

Step-by-step explanation:

Let B represent blueberry pie and P represent pumpkin pie.

      Kim: 12B + 8P = 208

- Krystal: 10B + 8P = 196

                2B         =   12

                  B         =    6

Input B = 6 into either of the equations to solve for P

10B + 8P = 196

10(6) + 8P = 196

 60  + 8P = 196

           8P = 136

             P = 17

When all the terms of a geometric sequence are added, then that expression is called geometric series.

Let's suppose its initial term is, the multiplication factor is  r

and let it has total n terms, then, its sum is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

Given the sum of the geometric series is 44,240, while the number of terms is 9. Also, the common ratio of the series is 3.8. Thus, we can write,

Sₙ = a(rⁿ-1)/(r-1)

44240 = a(3.8⁹ - 1)/(3.8 - 1)

44240 = a 59005.3933

a = 0.75

Hence, the first term of the given geometric series is 0.75.

Answer:

[tex]V = 983.73\ cm^3[/tex]  or [tex]V = 983\ ^{11/15}\ cm^3[/tex]

Step-by-step explanation:

By definition the volume of a rectangular prism is the product of its length (l) by its width (w) by its height (h). This is:

[tex]V = lwh[/tex]

In this case we know that

l = [tex]8\ ^{1/2}[/tex] centimeters

l = [tex]8 + \frac{1}{2}=8.5[/tex] centimeters

w=  [tex]9\ ^{1/3}[/tex] centimeters

w = [tex]9 + \frac{1}{3}=9.333[/tex]  centimeters

h=  [tex]12\ ^{2/5}[/tex] centimeters

h = [tex]12 + \frac{2}{5}=12.4[/tex]  centimeters

Then

[tex]V = (8.5)(9.333)(12.4)\ cm^3[/tex]

[tex]V = 983.73\ cm^3[/tex]

[tex]V = 983\ ^{11/15}\ cm^3[/tex]

Answer:

112 adults

20 children

Step-by-step explanation:

In order to solve this problem, we must create system of equations. By definition, system of equations are two equations which help you find unknown variables.

As for this problem, we need to set two variables for each type of person.

Let x represent adults

Let y represent children

We can break the question apart, and form equations based on the information given.

"tickets for adults cost $3.25 while tickets for children cost $2.25 and total receipts for the concert was $364"

$3.25x + $2.25y = $364

Now, we must form our second equation based on the information given.

"If 132 people attend a concert" "how many of each went to the concert"

x + y = 132

Solve for x, or the total number of adults

x = -y + 132

3.25(-y + 132)+ 2.25y = $364

Distribute 3.25

3.25 * -y = -3.25y

3.25 * 132  = 429

-3.25y + 429 = $364

Subtract 429 from both sides

364 - 429 = -65

-3.25y = -65

Now divide both sides by -3.25 to find the value of y.

y = 20

Therefore, 20 children attended the concert.

In order to find the total amount of adults who attended, subtract 20 from the total number of people that attended.

132 - 20 = 112

So, 112 adults attended as well as 20 children.

To find the number of adults and children who attended the concert, we can set up a system of equations and solve for the variables. Using the given information, we can determine that there were 67 adults and 65 children at the concert.

To solve this problem, we can use a system of equations. Let's assume that the number of adults who attended the concert is 'a' and the number of children is 'c'. We can form two equations from the given information:

Now, we can solve the system of equations to find the values of 'a' and 'c'.

Solving Equation 1 for 'a', we get a = 132 - c.

Substituting this value of 'a' into Equation 2, we get 3.25(132 - c) + 2.25c = 364.

Expanding and simplifying the equation gives us 429 - 3.25c + 2.25c = 364.

Combining like terms, we get -c = -65.

So, c = 65.

Substituting this value of 'c' into Equation 1, we get a + 65 = 132.

Solving for 'a', we get a = 67.

Therefore, there were 67 adults and 65 children at the concert.

(h, k) - center

r - radius

We have the center at (3, -2) and the radius r = 9. Substitute:

By adding the system of equations and solving for x, then substantifying back into the first equation, we find that y in this system of equations is approximately 3.5556.

To find the value of y in the given system of equations, you can add the two equations together. The first equation is x+3y=1 and the second equation is 2x – 3y = -30. Here are the steps:

This value, 3.5556, is the value of y in the solution for the system of equations.

Step-by-step explanation:

When the object hits the ground, h = 0.

0 = -21.962x + 114.655

x = 5.2

From the table, the object landed at x = 4.6 seconds.  So the line of best fit predicts a time 0.6 seconds greater than actual.

The original height is when x = 0.

h = -21.962(0) + 114.655

h = 114.7

So the line of best fit predicts the object was dropped from a height of 114.7 meters.  This is higher than the actual 100 meters.

At x = 3.5:

h = -21.962(3.5) + 114.655

h = 37.8

So the line of best fit estimates the object reached a height of 37.8 meters after 3.5 seconds.

We know that at x = 0, h = 114.7.  This is more than 4 meters from the actual initial height of 100 m.

Therefore, the answer must be A.

Answer:

A. According to the line of best fit, the object would have hit the ground 0.6 seconds later than the actual time the object hit the ground.

Answer:

To find the value of missing exponent, we have to split the number which is in other side of equal sign (which is not having power) as the multiple of base of the missing exponent.

On both sides, powers have the same base, so their exponents must be equal.

Step-by-step explanation:

Write the missing exponent:

25=5^x

Let x be the missing exponent.

To find the value missing exponent, we have to split the number which is in the left side as the multiple of the base of the missing exponent.

That is,

25=5*5 or 5^2

Now,

5^2=5^x

Powers have the same base so their exponent must be equal.

Hence the missing exponent is 2
