Answer:

a₁₃ = 4096

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{2}{1}[/tex] = 2 , then

a₁₃ = 1 × [tex]2^{12}[/tex] = 4096

Answer:

x + 3

Step-by-step explanation:

3x+2 is the 2nd term

2x-1 is the commind difference (d)

so you just need to substract it

3x+2

-(+2x-1) -------transpose -2x+1

3x+2

-2x+1

---------

x+3

Answer:

a is equal to x + 3

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

We are given the sequence:

a, 3x+2, b

And the common difference is 2x-1

Subtracting the second and the first terms:

3x + 2 - a

We can find the common difference since it's given:

3x + 2 - a = 2x - 1

Solving for a:

- a = -3x - 2 + 2x - 1

- a = -x - 3

a = x + 3

a is equal to x + 3

Answer:

8

Step-by-step explanation:

First, you add the 7 to both sides. Then you divide both sides by 9. This gets you left with x by its self on one side. x = 8

Answer:

x=8

Step-by-step explanation:

x=8 because if you add 65 and 7 you get 72 and when you divide it by 9 you get 8.

Answer:

B- Negative

Step-by-step explanation:

Since both numbers are on the left side of zero, they are both negative, and in your situation, A= -4.5 and B= -9. By trying to do -4.5+(-9), it will become -4.5-9, thus being negative

Answer:

We know that the distributive property says this:

a(b+c) = ab + ac

If we apply this to our case, we can put

3a(2b+c) = 3a * 2b + 3a * c

When we multiply numbers and letters, we should multiply both of them:

3a * 2b + 3a * c = 3*2*a*b + 3*a*c = 6ab +3ac

We can use this when we find a number multiplied by a parenthesis..

Answer:

6ab + 3ac

Step-by-step explanation:

3a(2b) + 3a(c)

6ab + 3ac

Answer:

1/5 times 24 is 24 1's, so we will divided 24 by 5, but since were estimating it will be 25/5 and we will get 5. That means 1/5 times 24 as an estimate will be 5. Hoped I helped!

Answer:

60

Step-by-step explanation

Okay, uh... this is gonna be confusing to explain.

So a hexagon's angles add up to 720. This means, we can find each angle's supplementary angle by subtracting each value we know away from the total.

So, we know the inside angle of angle 6 is 90.

So: 720-90=630

Now, typically, you would divide by the remaining angles, but we have basically 2 angles of different values since 1, 2, and 3 are equal, and 4 and 5 are equal.

However, we know that 1, 2, and 3 are 10 degrees less than 4 and 5. So if we "add" 10 degrees to each of those angles we get:

10*3=30

630-30=600

Now we made it as though each angle (1-5) is equal. So now we divide by 5.

600/5=120

This means the supplementary of angles 4 and 5 is 120, so we subtract that value from 180 since a straight angle is 180.

180-120=60

Now, to check this we reverse it.

(120*2)+(120*3)+(10*3)+(90)=

240+360+30+90=

600+30+90=

600+120=

720.

Um... I think this is it?? Your school is scary :o

Answer:

2.0 and 0.07   or 2.07

Step-by-step explanation:

hope this helps :)

The decimal form of numbers 2 and 7/100 is, 2.07

We have to give that,

Write 2 and 7/100 in decimal form.

Now, Write 2 and 7/100 in decimal form as,

⇒ 2 and 7/100

⇒ 2 7/100

⇒ (100 × 2+ 7)/100

⇒ 207/100

⇒ 2.07

Hence, the Number is, 2.07

Let as consider, we need to find the fixed fee.

Given:

Cost of each ticket = $18

Number of tickets = 5

Total cost = $93

To find:

The fixed fee.

Solution:

Let x be the fixed fee..

Cost of 1 ticket = $18

Cost of 5 ticket = $(5 × 18)

                         = $90

Total cost 5 tickets = Fixed fee + Cost of 5 tickets

[tex]93=x+90[/tex]

[tex]93-90=x[/tex]

[tex]3=x[/tex]

Therefore, the fixed fee is $3.

Answer:

9 inches

Step-by-step explanation:

Here, we want to know the greatest length of the third side

We apply the triangle inequality theorem here

To get the third side, then the sum of the lengths of the two must be greater than the measure of the third side

let us call the third side x

Then;

5 + 5 > x

10 > x

The highest whole number before 10 is 9: so it is the greatest possible whole number the base of the isosceles triangle can have

Answer:

1000 cajas

Step-by-step explanation:

De la pregunta anterior, sabemos que:

Un camión lleva 200 cajas.

Cada caja contiene 20 paquetes de café de un cuarto de kilo.

Esto significa

1 caja = 20 paquetes (1/4 kilo) de café

1 caja = paquetes de 5 kilos de café

Ya que tenemos 200 cajas en el camión

1 caja = 5 kilo

200 cajas = x

Cruz multiplicar

x = 200 × 5 kilo

x = 1000 kilos

Por tanto, los kilos de café que puede transportar el camión son 1000 kilos.

Answer: extrapolation, and 25 months

Step-by-step explanation:

I took the Plato test and got it right, but if you want to know. Interpolation means based on the numbers given you could see the answer, extrapolation means you have to go farther than the last plot point given to get your answer. Which you do since it does not go past 12 months.

The second answer you can roughly get by pluging in each of the choices in the equation for x

For example: y=-200.22(25)+5015.20

That should give you an answer pretty close to zero so there is your answer
