Answer:

[tex]T_7 = \frac{64}{729}[/tex]

Step-by-step explanation:

Given

[tex]a =1[/tex]

[tex]r = \frac{2}{3}[/tex]

Required

Determine the 7th term

The nth term of a gp is:

[tex]T_n = a * r^{n-1[/tex]

So, we have:

[tex]T_7 = 1 * \frac{2}{3}^{7-1[/tex]

[tex]T_7 = 1 * \frac{2}{3}^{6[/tex]

[tex]T_7 = 1 * \frac{2^6}{3^6}[/tex]

[tex]T_7 = 1 * \frac{64}{729}[/tex]

[tex]T_7 = \frac{64}{729}[/tex]

Answer:

y = 23

x = -4.5

Step-by-step explanation:

Given:

Equation

8x + y = -13 ......eq1

8x + 2y = 10​........eq2

Find:

Solution

Computation:

Eq2 - Eq1

y = 23

From eq1

8x + y = -13

8x + 23 = -13

8x = -36

x = -4.5

Answer:

6x + 7.50y ≥ 75

Step-by-step explanation:

Let x = # of hours he walks the dog

     y = # of hours he washes cars

We also know that he cannot have any negative hours, so 2 lines that we need to graph will be y = 0, with everything above this line shaded in, and x = 0, with everything to the right of this line shaded in and these lines will be solid because you can have 0 hours.

Another equation will be x + y ≤ 15. We graph the line, which will be solid, y = -x + 15, and shade everything to the left of this line.

The last equation will be 6x + 7.50y ≥ 75. We graph this solid line, y ≥ (-6x + 75)/7.50 & shade everything to the right of this line. Any point inside the area shaded in by all 4 equations will be an answer. I'll leave this up to you.

Hope this helps!

Answer:

30

Step-by-step explanation:

Again there are TWO sides so it would be 50% chance of getting head, or 50% of getting tail. So it would probably be 30

Answer:

"50% of the time"

Step-by-step explanation:

Because the probability is limited to only 2 sides you have a 50% chance it will land on either heads, or tails.

There may not be an image representation of this question but I can probably answer this. If the smaller wheel causes the the bigger wheel to rotate, the wheel will rotate 30.0° about everytime. this only depends on the speed of the smaller wheel.

Answer:

x= 43, y=215

Step-by-step explanation:

Let one number be x,

Let the other number be y.

x= 5y

x - y= 172

Putting value of x in equation 2.

5y - y = 172

4y = 172

y= 172/4

y= 43

Putting value of y in eq. 1

x= 5(43)

x=215.

Tiled floor with 225 square tiles means the area of the square room is 225.

Formula needed: A = (side)^2 or in short

A = s^2.

We need to find s.

225 = r^2

sqrt{225} = sqrt{r^2}

15 = r

There are 15 tiles are along an edge of the room.

Answer:

87/448

Step-by-step explanation:

Answer:

a translation of 5 units to the right followed of a translation of 2 units up.

Step-by-step explanation:

This seems to be a translation because if we measure the base of both triangles, we can see that the base of the blue triangle is 5 units long, and the base of the red triangle is also 5 units long.

To find the translation in this case, is easier to only analyze one point, so let's call A as the top vertex in the blue triangle and A' as the top vertex in the red triangle.

Here we only need to see the change between A and A'

So first, let's find the coordinates of both points.

The top vertex of the blue triangle is A (-3, 5)

The top vertex of the red triangle is A' (2, 7)

Now we need to find the difference between these points, this is the direct subtraction:

A' - A

(2, 7) -  (-3, 5) =  (2 - (-3), 7 - 5) = (5, 2)

So we get this, (5, 2)

This means that the translation is a motion of 5 units in the x-axis (because the number is positive, this means that the motion is in the positive x-axis)

And a translation of 2 units up.

Then the translation that maps the blue triangle into the red triangle is:

a translation of 5 units to the right followed of a translation of 2 units up.

Answer:

NICE

Step-by-step explanation:

Answer:

We have 4 triangles with base 3 and height 4 and a square with side length 3 so:

Triangles:

The area for a triangle is calculated by [tex]\frac{bh}{2}[/tex] where b is the base and h is the height so we have [tex]\frac{12}{2}\cdot 4[/tex] so we have a total area of 24.

[b]Square:[/b]

The area of a square is calculated by [tex]s^{2}[/tex] where s is the side length so we have the area is 9.

Now we put them together for the surface area so we get 24 + 9 = [tex]\boxed{33}[/tex]

Answer:

2 product of x & adding it from 3 is equals to 5 ..

9514 1404 393

Answer:

Step-by-step explanation:

Let b represent the base of the triangle in meters. Then the height is ...

  h = 3 +2b

and the area is ...

  A = 1/2bh

  8 = 1/2(b)(3 +2b)

  16 = 3b +2b^2 . . . . . . . multiply by 2 and eliminate parentheses

  2(b^2 +3/2b + (9/16)) = 16 + 9/8 . . . . . . complete the square

  2(b +3/4)^2 = 17.125

  (b +3/4)^2 = 8.5625 . . . . . divide by 2

  b + 0.75 = √8.5625 ≈ 2.9262

  b = -0.75 +2.9262 = 2.1762

  h = 3 +2b = 7.3523

The base is about 2.18 meters and the height is about 7.35 meters.

Answer:

y=16 bc 17 -16 =1 which if u do backward equals the same thing

and all together is

18y+1 and just leave it like that dont touch the numbers or anything bc you cant take a 1 and join it with a variable

you can only join numbers with numbers and variables with variables

Answer:

0.7727 = 77.27% probability that it is small or green

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

11 large + 11 small = 22 total marbles = 22 total outcomes

11 small marbles  + 6 green large marbles = 17 desired outcomes.

What is the probability that it is small or green?

[tex]p = \frac{17}{22} = 0.7727[/tex]

0.7727 = 77.27% probability that it is small or green
