63.5 that's the answer am good at maths

Answer:

Step-by-step explanation:

To make it easier to understand, consider the exponent of a number with no decimals, with 1 decimal and with 2 decimals:

Since our given number is (0.23)⁹, with 2 decimal places, its exponent will have 2*9 = 18 decimals.

Answer:

44

Step-by-step explanation:

Isosceles triangles have two angles that are equal.  If the two equal angles are 68

We have  68, 68, and an unknown angle x

They add to 180

68+68+x = 180

136+x=180

x =180-136

x =44

Answer:

5x4

Step-by-step explanation:

5x4=20

Answer:

2 times 10 equals 20, or 5 times 4 equals 20.

Step-by-step explanation:

This is as simple as understanding what multiplies together to equal 20. I hope this helps!

Step-by-step explanation:

(2.5 , 6)

Answer:

Assuming your equations are:

x-3y=3

4x+3y=-3

The answers are x = 0 and y = -1.

Step-by-step explanation:

See the image for the graph.

The Correct choices are :

x = -1

Step-by-step explanation:

2(x - 1) + 4 = -(x + 6) + 5

2x - 2 + 4 = -x - 6 + 5

2x + 2 = -x - 1

2x + x = -1 - 2

3x = -3

x = -1

Answer:

x+2

Step-by-step explanation:

This is because they are both odd numbers, and rather than Luke being the younger brother, ad having to subtract, he is the older brother so you have to add.

frequency is the number of days in this problem

the number of questions is on the bottom part and the days are on the left part

Answer:

Area of the farm is 600m²

Area of the garden is 120m²

Step-by-step explanation:

30m x 20m = 600m²

6m x 20m = 120m²

Answer:

So for the coorfinates of F, you have to see how far it is from y=1. The F is 2  points under the 1 so you have to count 2 above the 1. So the point would be (7,3). Same for the other ones. For example like D. It's 2 above 1 so its going to be 2 under which would result in (1, -1)

Answer:

45 feet

Step-by-step explanation:

4 and 1/2 inches

1/2 =5 feet

put the mixed number into an improper fraction

9/2 *5 = 9*5 = 45 feet

Answer:

18.125

Answer:

[tex]x=61[/tex]

Step-by-step explanation:

We can find the angle directly above the [tex]2x+8[/tex].

We know that because they both lie on a straight line, the other angle is [tex]180-(2x+8)=172-2x[/tex].

Aha! We have a path to the solution!

[tex]172-2x=x-11[/tex] because of the parallel line angle theorem(I forget what it's called).

We then add [tex]2x[/tex] and [tex]11[/tex] to both sides to get [tex]183=3x[/tex].

Lastly, we divide by [tex]3[/tex] to get [tex]61=x[/tex].

So, [tex]\boxed{x=61}[/tex] and we're done!

Answer:

this sequence is geometrical sequence

and it's formula is

[tex]y = a {r}^{n} \\ here \: a \: is \: first \: number \: is \: equal \: 1 \\ and \: the \: ratio \: is \: r \: is \: equal \: - 3 \\ y = 1 \times {( - 3)}^{n} [/tex]

Answer:

You need to move to move up 3 because the number is positive.

Step-by-step explanation:

If the numerator is positive you move up, if it is negative you move down. For the denominator (the number on the bottom) you move to the right if positive or the left if negative.

Answer:

Slope =rise/run Slope = rise/run

Explanation:

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run

Step-by-step explanation:

A = Future value of the amount invested

P = principal (amount of money invested) = $9,200

i  = interest rate =  6% or 0.06

n = number of compounding periods (it is the number of times the interest is compounded).

For the Interest Rate per Compounding Period column, you'll have to divide the interest rate by its corresponding compounding period (please see the definitions of each compounding periods below). For example, the interest rate per compounding period (compounded annually) = interest rate ÷ number of compounding periods ( [tex]\frac{i}{n}[/tex] ) = 0.06/1 = 0.06 or 6%

For the Number of Compounding Periods column, you'll have to multiply (t ) by the number of compounding periods (n):

t × n =  15 years × 1  =  15

The Compound Interest Formula column is pretty self-explanatory--you'll just have to follow the given formula. You need to make sure that you change the values for i and n  for every row.

Compounding periods (n):

compounding annually: n = 1  

compounding semiannually: n = 2

compounding quarterly: n = 4

compounding monthly: n = 12

compounding weekly: n = 52

compounding daily: n = 365

You'll have to use these values into your Compound Interest formula.

I will do the 2nd row (semi-annually) for you as a guide, but you'll have to do the rest so that you could familiarize yourself on how to do it.

Interest Rate per Compounding Period  = i / n = 0.06/2 = 0.03 or 3%

Number of Compounding Periods = t × n =  15 years × 2 = 30

Compound Interest Formula:  [tex]A = 9,200(1 + 0.03)^{30}[/tex]

Final Amount  = 22,330.81
