Answer: 24.9

Step-by-step explanation:

Answer:

x²y²z is the Greatest Common Factor

Therefore,

6x³y²z⁴ - 7x²y⁵z = x²y²z (6xz³ - 7y³)

Step-by-step explanation:

Given the expression

6x³y²z⁴ - 7x²y⁵z

The first step is to factor out the greatest common factor from each term

6x³y²z⁴ = 2 · 3 · 6 · x · x · x· y · y · z · z · z · z

7x²y⁵z =  7 · x · x · y · y · y· y · y · z

So

G.C.F = x · x . y · y . z

G.C.F = x²y²z

Thus, x²y²z is the Greatest Common Factor

Therefore,

6x³y²z⁴ - 7x²y⁵z = x²y²z (6xz³ - 7y³)

Answer:

√2 + x

Step-by-step explanation:

To obtain the hypotenus, h:

Using Pythagoras rule :

h² = opposite² + Adjacent²

Opposite = √2

Adjacent= x

h² = (√2)² + x²

Take the square root of both sides

h = √2 + x

Hence, the hypotenus is √2 + x

Answer:

JP = 18

PS = 9

Step-by-step explanation:

ps being the shorter side is one third of the line JS and 1/3 of 27 is 9

jp being the longer side is 2/3 the length of js and 2/3s of 27 is 18

Answer:

JP=18

PS=9

Step-by-step explanation:

centroid divides median in the ratio 2:1

so,

JP:PS=2:1

Now take PS be x

then JP=2x

now, given JS=27

JP+PS=27

2x+x=27

3x=27

x=9

so,

PS=9

AND JP=18

Answer:

[tex]S_9 = 442845[/tex]

Step-by-step explanation:

Given

[tex]Sequence: 45,135,405,1215,3645[/tex]

Required:

The sum of the first 9 terms

We'll solve this question using the explicit formula:

Because it is a geometric sequence, we first calculate the common ratio (r).

[tex]r = \frac{T_n}{T_{n-1}}[/tex]

Let n = 2;

So, we have:

[tex]r = \frac{T_2}{T_{2-1}}[/tex]

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]T_2 = 135; T_1 = 45[/tex]

So, we have:

[tex]r = \frac{135}{45}[/tex]

[tex]r = 3[/tex]

Explicitly, the sum of  n terms of a geometric sequence is:

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

[tex]a = T_1 = 45[/tex]

[tex]r = 3[/tex]

[tex]n = 9[/tex]

The formula becomes:

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

[tex]S_9 = \frac{45* (3^9 - 1)}{3 - 1}[/tex]

[tex]S_9 = \frac{45* (3^9 - 1)}{2}[/tex]

[tex]S_9 = \frac{45* (19683 - 1)}{2}[/tex]

[tex]S_9 = \frac{45* (19682)}{2}[/tex]

[tex]S_9 = 45* 9841[/tex]

[tex]S_9 = 442845[/tex]

Hence, the sum of the first 9 terms is 442845

Answer:

The complete table is shown below:

Graph        Vertical Change         Horizontal Change         Slope

A                            6                                  3                             2

B                            2                                  8                             1/4

C                          40                                20                            2

Step-by-step explanation:

Graph A

From graph A, it is clear that

(x₁, y₁) = (1, 3)

(x₂, y₂) = (4, 9)

Vertical change = y₂ - y₁ = 9 - 3 = 6

Horizontal change = x₂ - x₁ = 4 - 1 = 3

Using the formula

Slope = m =  Vertical Change / Horizontal Change

                =  [y₂ - y₁] /  [x₂ - x₁]

                =  [9 - 3] / [4 - 1 ]

                = 6 / 3  

                = 2

Thus, the slope of the line = m = 2

Graph B

From graph B, it is clear that

(x₁, y₁) = (2, 1.5)

(x₂, y₂) = (10, 3.5)

Vertical change = y₂ - y₁ = 3.5 - 1.5 = 2

Horizontal change = x₂ - x₁ = 10 - 2 = 8

Using the formula

Slope = m =  Vertical Change / Horizontal Change

                =  [y₂ - y₁] /  [x₂ - x₁]

                =  [3.5 - 1.5] / [10 - 2 ]

                = 2 / 8  

                = 1/4

Thus, the slope of the line = m = 1/4

Graph C

From graph C, it is clear that

(x₁, y₁) = (10, 35)

(x₂, y₂) = (30, 75)

Vertical change = y₂ - y₁ = 75 - 35 = 40

Horizontal change = x₂ - x₁ = 30 - 10 = 20

Using the formula

Slope = m =  Vertical Change / Horizontal Change

                =  [y₂ - y₁] /  [x₂ - x₁]

                =  [75 - 35] / [30 - 10 ]

                = 40 / 20  

                = 2

Thus, the slope of the line = m = 1/4

Therefore,

The complete table is shown below:

Graph        Vertical Change         Horizontal Change         Slope

A                            6                                  3                             2

B                            2                                  8                             1/4

C                          40                                20                            2

Answer:

15 possible combinations

Step-by-step explanation:

In order to find the total number of combinations possible, we need to multiply the total number of different colors by the total number of storage capacities that each phone can have. Using the values provided we would get the following arithmetic expression...

5 colors * 3 capacities = 15

Therefore, we can see that there are a total of 15 possible combinations with these variations.

Answer: Multiply 12 and 5 (by the same number) and add them to get whatever total ml of crayon wax is specified.

Ex: Total ml divided by 17, then find how many parts are red(12ml) and white(5ml)

Answer:

$41.33

Step-by-step explanation:

Let the money be x

Game cost = 2/3*x

balance= 1/3*x

x/3= 15.5

Solve for x

x= 15.5*3

x=$46.5

so his money was $46.5

Amount spent on Game

=2/3*46.5

=$31

He spent 2/3 of 15.5 on Jacket

=2/3*15.5

=$10.33

In all he spent =31+10.33 =$41.33

Answer:

t=0

Step-by-step explanation:

The first thing you want to do is isolate the varible t. So you going to subrtact the 45 from both sides, which leaves you with, 5t=0. Next you are going to divide 5 from both sides, which leaves you with t=0. To make sure its right, plug it in. 45+5(0)=45. 45=45.

Answer:

x = -6

-18+4y=0 => 4y=18 =>y=18/4=9/2

Y=5

3x+20=0 => x=3x= -20=> x= -20/3

Step-by-step explanation:

The value of the given expression is -38.

Simplify fractions by cancelling all the common factors from both the numerator and the denominator and writing the fraction in its lowest/simplest form.

Given an expression, 3x + 4y

Putting x = -6 and y = -5, we get,

3x(-6) + 4x(-5)

= -18-20

= -38

Hence, The value of the given expression is -38.
