Answer:

Divide the numbers 36/6 = 6

= 6y + y + 2 * 4y

Multiply the numbers 2 * 4

= 6y + y + 8y

Add like terms

= 15y

Answer:

a) square numbers

b) 9

Step-by-step explanation:

A square number is a number that can be made by multiplying a whole number by itself(49 is a square number because 7*7=49, 64 is a square number because 8*8=64).  The square root of 36 is 6.  The square root of 25 is 5.  The square root of 16 is 4.  Thus, following the pattern, the square root of 9 is 3.

Answer:

  12

Step-by-step explanation:

If there are x children on the bus at the start, after the first stop, there are (x-3) remaining. After two stops, the number on the bus is ...

  x/2 = x -3 -(1/3)(x -3)

Multiplying by 6, we have ...

  3x = 6x -18 -2(x -3)

  3x = 4x -12 . . . . simplify

  12 = x . . . . . . . . add 12-3x

There were 12 children on the bus at the start.

_____

Check

After 3 got off at the first stop, there were 12-3 = 9 remaining. 1/3 of those, or 9/3=3 got off at the second stop, so 9 -3 = 6 remained. This is half the original number, as required.

Answer:

9 years

the tree doubles in height

we can make a model

1 x 2 = 2

2 x 2 = 4

4 x 2 = 8

8 x 2 = 16

16 x 2 = 32

32 x 2 = 64

64 x 2 = 128

128 x 2 = 256

256 x 2 = 512

512 x 2 = 1024

Let's say 1024 is the maximum height

half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year

Step-by-step explanation:

By the Triangle Inequality Theorem, the sum of two sides should be greater than the length of the third side, while the difference of these two sides should be less than the length of this third side. Normally you would take the absolute value of the difference of these two side as you wouldn't know which is greater than the other!

The simplest way to prove whether these line segments can form a triangle, is by going against this theory. Let us prove that the line segment don't form a triangle. As you can see, adding 7 and 1 is greater than 1, respectively 7 and 7 is greater than 1. Thus -

Hey there! :)

Answer:

Second choice: 4.

Step-by-step explanation:

The constant of proportionality is also the slope, or rate of change. The slope formula can be used to solve this problem:

[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Plug in points from the graph into the equation.

[tex]m = \frac{4 - 0}{1 - 0}[/tex]

m = 4.

Therefore, the constant of proportionality is 4.

You'll be disappointed to find out these are *all* complex numbers, because the set of real numbers is a subset of the complexes.

Probably the question means to ask, "which of these numbers is strictly non-real?" in which case D would be the answer because it contains the square root of a negative number that introduces the imaginary unit i. All the other options are strictly real numbers.

Answer: (originally answered by DeanR so credit to him)

x=6

Step-by-step explanation:

x3579x = 100000 x + 35790 + x

100000 = 2380 × 42 + 40

35790 = 852×42 + 6

Working mod 42,

100000 x + 35790 + x = 40 x + 6 + x =  41x + 6 = 6-x  (mod 42)

So basically we need 6-x to be a multiple of 42, so between 0 and 9 that's x=6.

So our number is

635796 = 15138 × 42

Answer:

x=6

Step-by-step explanation:

All of the factors of 42 under are only 7 and 6. Substitute one of them for x. 7 is wrong so 6 is the answer.

Answer:

CI = 28 ± 3.09

Step-by-step explanation:

The sample size, n = 25

The sample mean, m = 28

Standard deviation, s = 7.5

Confidence interval is given as:

CI = Sample mean ± margin of error

We want to find 95% confidence level:

First, let us find the margin of error:

Margin of error = Critical value * standard error

To find the critical value, we need some parameters:

Standard error = [tex]s / \sqrt{n}[/tex]

=> [tex]SE = 7.5 / \sqrt{25}= 7.5 = 5 = 1.5[/tex]

The alpha value, ∝ = 1 - (confidence level / 100) = 1 - 95/100 = 1 - 0.95 = 0.05

Critical probability, p, is given as:

p = 1 - ∝/2 = 1 - 0.05/2 = 1 - 0.025 = 0.975

Now we need the degree of freedom:

df = n - 1 = 25 - 1 = 24

Therefore, the critical value is 2.06 (you can use an online t value calculator).

=> Margin of error = 2.06 * 1.5 = 3.09

Therefore, the confidence interval for the population mean is:

CI = 28 ± 3.09

Answer: Distance is 17

Step-by-step explanation:

[tex]d = √((x2-x1)2 + (y2-y1)2)[/tex]

Answer:

4 and 5/6; 29/6.

Step-by-step explanation:

3/7 of x is 2-1/14.

(3/7)x = 29/14

x = (29/14) * (7/3)

x = (29/2) * (1/3)

x = 29/6

3/7 of 4 and 5/6 is 2 1/14.

Answer:

Gabriella's average original speed was 56  [tex]\frac{mi}{h}[/tex]

Step-by-step explanation:

Let's use the equation that defines the average speed "v" of Gabriella during the time (t) that her trip took:

[tex]v = \frac{distance}{time} \\v=\frac{400}{t}[/tex]

Next let's write a similar average speed equation for the case in which she drove at (v - 7 mi/h) during the same time "t" and covered 350 miles:

[tex](v-7)=\frac{350}{t}[/tex]

Notice that the time "t" in the denominator appears equally in both equations we wrote, so let's isolate them on the right:

[tex]\frac{v}{400} =\frac{1}{t} \\and\\\frac{(v-7)}{350} =\frac{1}{t}[/tex]

now equal both expression since they both share the same value on the right, and solve for the unknown "v":

[tex]\frac{v}{400} =\frac{(v-7)}{350} \\350\,v=400\,(v-7)=\\350\,v=400\,v-2800\\2800=50\,v\\v=\frac{2800}{50} \,\,\frac{mi}{h}\\v=56\,\,\frac{mi}{h}[/tex]

Answer:

4006.5

Step-by-step explanation:

4004 + 4009 = 8013

8013 ÷ 2 = 4006.5

Answer:

Hey!

Your answer is 4,006.5

Step-by-step explanation:

We get the MEAN by ADDING ALL THE VALUES UP and DIVIDING IT BY THE TOTAL AMOUNT OF SEPERATE NUMBERS!

So...

4,004 + 4,009 = 8,013

WE DIVIDE 8,013 BY 2...

8,013 / 2 = 4006.5!

Answer:

t = 4

Step-by-step explanation:

you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.

The value of t is 4.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

The temperature in January = 12 °F

And the low temperature is = -8 °F

The equation of temperature t can be given as

t= high temperature + low temperature

t= 12 - 8

t=4

The value of t is 4.

Answer:

444

Step-by-step explanation:

13 + 34 + 25 + 10 + 8 = 90

10/90 * 4000 = 444

Answer: You will expect 444 white cars passed by.

Step-by-step explanation:

The are 5 different colors so we need to find the probability of white cars.

There are 10 white cars But we need to find the total number of cars in all.

13+34+25+10+8 = 90

so the probability of a white car passing by is 25/90 = which reduces to 10/90  

Now multiply 1/9 by 4000.

1/9 * 4000  =  444

Answer:

41.36% decrease

Step-by-step explanation:

Since it told us that the total amount of people was 1,100 people, we know our percentage is going to have to be x/1100.

We calculate how many less people came to the pool after the weeks have passed, which totals up to 455 people (455 people decrease).

So,

455/1100 = 0.413636 or 41.36% decrease.
