Answer:

Inequality:  125x + 55 < 600

Solution of inequality: x < 4.36

Final answer: 4 hours

Step-by-step explanation:

Let the number of hours be x.

1 hour costs $125.

2 hours cost $125 × 2

3 hours cost $125 × 3

x hours cost $125 × x or simple 125x.

The assistant costs $55.

The total cost is 125x + 55.

The cost must be under $600, so

125x + 55 < 600

Subtract 55 from both sides.

125x < 545

Divide both sides by 125.

x < 4.36

In theory he can be hired for any amount of hours under 4.36 hours, but he probably works only full hours, so you need to round down to 4 hours.

4 hours

Answer:

The weight : 9 pound

Lamar would pay for his dinner : $71

Step-by-step explanation:

Let x represent the weight of the lobster

the cost of the dinner at restaurant 1 is 4x + 35  

the cost of the dinner at restaurant 2 is 3x + 44

Now ,we have to solve the equation :  

4x + 35 = 3x + 44

-3x - 35   -3x  - 35    -> trying to get all x terms on one side. other just #

4x - 3x = 44 - 35

⇔ 1x = 9

⇔ x = 9

In this case Lamar would pay the same amount for his dinner at any restaurant:

the price = 4×(9)+35 = 71

               = 3×(9)+44 = 71.

Hope this helps, Let me know if you have any question/concerns !

Step-by-step explanation:

General form of a geometric sequence:  [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the first term and [tex]r[/tex] is the common difference)

Given geometric series:   8 + 40 + 200 + ... + 15625000

[tex]\implies a_1=8[/tex]

[tex]\implies a_2=40[/tex]

[tex]\implies a_3=200[/tex]

To find the common ratio [tex]r[/tex], divide consecutive terms:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{40}{8}=5[/tex]

Therefore:

[tex]\implies a_n=8(5)^{n-1}[/tex]

To find n when [tex]a_n=15625000[/tex] :

[tex]\implies 8(5)^{n-1}=15625000[/tex]

[tex]\implies (5)^{n-1}=1953125[/tex]

[tex]\implies \ln (5)^{n-1}=\ln1953125[/tex]

[tex]\implies (n-1)\ln 5=\ln1953125[/tex]

[tex]\implies n=\dfrac{\ln1953125}{\ln5}+1[/tex]

[tex]\implies n=10[/tex]

Sum of the first n terms of a geometric series:

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

Therefore, sum of the first 10 terms:

[tex]\implies S_{10}=\dfrac{8(1-5^{10})}{1-5}[/tex]

[tex]\implies S_{10}=19,531,248[/tex]

keeping in mind that a rhombus is also a parallelogram, namely a quadrilateral with parallel opposite sides, however, a rhombus sides are all the same length, and its diagonals meet at right-angles, Check the picture below.

The ratio of the required trigonometric function sin b₂° as per the given measurement of the quadrilateral is equal to 39/ 50.

Let us consider quadrilateral ABCD be rhombus.

Using the properties of the rhombus,

All the sides are congruent to each other.

Here, AB = 5 cm

This implies,

AB = BC = CD = AD = 5 cm

And Intersection of the diagonal is point 'O'.

In rhombus diagonals bisects each other at 90 degrees.

Measure of angle BOC = 90 degrees.

Triangle BOC is right angled triangle.

OC = 3.9 cm

sin b₂° = opposite side / hypotenuse

           = OC / BC

           = 3.9 / 5

           = 0.78

            = 78 / 100

            = 39 / 50

Therefore, the ratio of the function sin b₂°  is equal to 39 / 50.

This is simply because the x coordinate is 6 and the y coordinate is 2.

The line x = 6 is a vertical line in which all points on it have an x coordinate of 6. It goes through 6 on the x axis.

The line y = 2 is horizontal where all points on it have a y coordinate of 2.

The vertical and horizontal lines intersect at (6,2)

9) volum = width× lenght × height

= 2×3×7 = 42 m³

10) = 7³ = 343 cm³

Answer:

Question 9: Volume = 42m

Question 10: Volume = 343cm

Step-by-step explanation:

Volume for a rectangular prism: V = length x height x width

Question 9:

Length = 7m

Width = 2m

Height = 3m

V = (7m) x (2m) x (3m)

V = 14m x 3m

Volume for a cube: V = a^3 → this is the formula since all sides are the same length

Question 10:

Length = 7cm

Width = 7cm

Height = 7cm

V = (7cm) x (7cm) x (7cm)

V = 49cm x 7cm

V = 343

OR

V = a^3 → (7)^3

The distance between the coordinates of house and store is D = 17 miles, or about 4.12 miles

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

Given data ,

Let the first point be P = P ( -8 , -9 )

Let the second point be Q = Q ( -4 , -10 )

Now , Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

D = √ ( -8 + 4 )² + ( -9 + 10 )²

On simplifying , we get

D = √ ( 4 )² + ( 1 )²

D = √17 units

And , 1 unit = 1 mile

So , √17 units = 4.12 miles

Hence , the distance between Jose's house and the store is √17 miles, or about 4.12 miles

Answer:

B. x-(0.5x+20)=300

Step-by-step explanation:

Because you add 20 to half of John's monthly allowance, and 0.5x is saying John's allowance divided by 2. Then you have Melissa's allowance, which then you add to John's allowance to get the total of $300 combined.

The equation that describes the situation would be; A. x-(0.5x+20)=300

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given that Melissa and John get a combined monthly allowance of $300. Melissa's monthly allowance is $20 more than half of John's monthly allowance.

When x represents John's allowance, in dollars

Since we add 20 to half of John's monthly allowance, 0.5x is saying John's allowance is divided by 2.

Now we have Melissa's allowance, which then adds to John's allowance to get a total of $300 combined.

The equation becomes as;

x-(0.5x+20)=300

Answer:

Step-by-step explanation:

2 + 4i + 3 - 7i       Bring like terms together:

= 2 + 3 + 4i - 71

= 5 - 3i.

Answer:

5 - 3i

Step-by-step explanation:

Real numbers are a subset of the complex numbers. Therefore it would only make sense that the complex numbers follow the same rule of additivity and multiplication as real numbers do:

[tex] \textbf{Let's see if the sequence is Arithmetic :} [/tex]

[tex] \textsf{Since the common difference is same, } [/tex] [tex] \textsf{we can infer that it's an Arithmetic progression} [/tex] [tex] \textsf{with common difference of -5} [/tex]

Sequence: -29, -34, -39, -44, -49, ...

First we need to identify the terms:

If the sequence is arithmetic, [tex]\boxed{\sf \bold{second \ term = \dfrac{first \ term+third \ term}{2} }}[/tex]

If the sequence is geometric, [tex]\boxed{\sf \bold{second \ term = \sqrt{first \ term \ x \ third \ term} }}[/tex]

=======================================

Check for arithmetic

[tex]\rightarrow \sf -34 = \sf \dfrac{-29 +(-39)}{2}[/tex]

[tex]\rightarrow \sf -34 = \sf \dfrac{-68}{2}[/tex]

[tex]\rightarrow \sf -34 = -34[/tex]       [Hence it's arithmetic series]

To find common difference. we have to think of how to go to next term.

first term: -29

to go the second term, subtract by -5

-29 -5 = -34, second term

-34 - 5 = -39, third term

Hence, common difference: -5

Here is an example of a systems equation with 3 variables:

x+y+z=2

6x-4y+5z=31

Step-by-step explanation:

Using elimination:

x+y+z=2

5x+2y+2x=13

5x+2y+2x=13

- 2x-2y-2z-4

____________

3x=9

x=9

Using substitution:

9+y+z=2

y=z-7

9+z-7+z=2
