During the same classifying activities, Haily said -√49 is an integer and Josh stated it is a rational number. Who is correct and why?

Answer:

y = 6x

Step-by-step explanation:

So for this we simply find a x and y coordinate (ex. (10, 60))

Since we see that the y coordinate is 6 times of the x coordinate, we know that the equation for this proportional relationship is y = 6x.

Hope this helps!

429 cm²

A(blue) =

= 2×6cm×10cm + 2×6cm×8cm + 8cm×10cm + (8cm×10cm - 5cm×4cm)

= 120cm² + 96cm² + 80cm² + 60cm²

= 356 cm²

A(green) =

= 4cm×5cm + 2×5cm×5cm/2 + 4cm×7cm

= 20cm² + 25cm² + 28cm²

= 73 cm²

A(total) =

= A(blue) + A(green)

= 356 cm² + 73 cm²

= 429 cm²

Hello! :)

Answer:

[tex]\huge\boxed{751}[/tex]

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit:  (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.

Answer: Rational numbers are numbers that can be written as a ratio of two integers.

Step-by-step explanation:

Answer: By definition, that is why they are called rational. They usually look like fractions: an integer in the numerator and an integer in the denominator.

Step-by-step explanation: Decimal equivalents of fractions are also rational numbers. Some decimal equivalents are not actually rational because the values they represent are not rational. For example: Pi. and the square roots of most integers 2,3,5,6...

Answer:the steps you used to solve the equation and find the amount of Carrie's allowance. Linear equation:  14a + 13a = 23; 27 a = 14; a = 14/28

Step-by-step explanation:  

1. change the fraction using the lowest common dominator

2. combine the like terms of the variable

3. use the subtraction property of equality

4. Check all the occurred

Answer: Sample Response: First, the like terms had to be combined using the lowest common denominator (LCD). Then the subtraction property of equality was used to isolate the variable term. Finally, both sides of the equation were multiplied by the reciprocal of the coefficient to solve for a.

Step-by-step explanation:

ABCD and 4|CD

(A.1000)+(B.100)+CD/4

100(10.A+B)+CD/4

100(10.A+B)/4 + CD/4

Thus,

25(10.A+B) + CD/4, because 4|CD

Brazil number one

Answer:

:ABCD and 4|CD

(A.1000)+(B.100)+CD/4

100(10.A+B)+CD/4

100(10.A+B)/4 + CD/4

Answer:

See explanation

Step-by-step explanation:

You can see that each time the number is doubling cuz 0.25 times 2 is 0.5 and so on. So now we know that the numbers are increasing so the next 3 terms have to be 2,4, and 8

Answer 123

Step-by-step explanation:

Answer:

458

Step-by-step explanation:

There are only 4 3-digit numbers that have a 5 in the ten’s place and the one’s place is twice of the hundreds place.  

152, 54, 356, and 458

If we reverse the order of the digits, we see that 458 becomes 854.

854-458=396

Answer:

-1, -4, 2, 4

Step-by-step explanation:

The are ascending

Answer:

Step-by-step explanation:

|x+3| - 2 > 9

First add two to both sides

That's

| x + 3 | - 2 + 2 > 9 + 2

Simplify

We have

| x + 3 | > 11

Apply the absolute rule

That's

If | u| > a where a > 0 then

u < - a or u > a

So we have

x + 3 < - 11 or x + 3 > 11

For x + 3 < - 11

x + 3 < - 11

x < - 11 - 3

x < - 14

For x + 3 > 11

x + 3 > 11

x > 11 - 3

x > 8

Combine the intervals

We have the final answer as

Hope this helps you

Answer:

x > 8 ∪ x < -14

Step-by-step explanation:

Start by adding 2 to both sides, obtaining the simpler inequality

|x+3| >11

Rewriting this as | x -(-3) | >11 makes the solution easier to visualize.  Think of (or draw) a number line with an open circle at x = -3.  This is the "center."  

| x -(-3) | >11 tells us that x is either 11 units greater than -3 or 11 units smaller than -3:  

x > 8 ∪ x < -14

= 26,(6)

≈ 26,7

C = 5/9(F - 32)

= 5/9(80 - 32)

= 5/9(48)

= 5×48/9

= 240/9

= 26,(6)

≈ 26,7

Answer:

  6^6

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

In this problem, that means ...

  (6^9)/(6^3) = 6^(9-3) = 6^6

__

It can help to remember that an exponent signifies repeated multiplication. Written out without exponents, the problem is ...

  [tex]\dfrac{6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6}{6\cdot6\cdot6}=6\cdot6\cdot6\cdot6\cdot6\cdot6=6^6[/tex]

Note that the 3 instances of 6 in the denominator cancel 3 from the numerator. Clearly, the effect is the same as subtracting exponents.

Answer: 6^6

Step-by-step explanation: Formula - (a^b)/(a^c) = a^(b-c)

keeping the formula in mind;

= 6^9/6^3= 6^(9-3)

= 6^6

● Answer:

b) 24 cm

● Step-by-step explanation:

l + 4 = 2w => l = 2w - 4

5w + 6 = P => 5w + 6 = 2w + 2l

5w + 6 = 2w + 2(2w - 4)

5w + 6 = 2w + 4w - 8

6 + 8 = 6w - 5w

w = 14

l = 2x14 - 4

l = 28 - 4

l = 24 cm

Answer:

y = 9

Step-by-step explanation:

We notice that both points have a y-coordinate of 9. Since they are the same, the equation must be y = 9 because the function can't "dip" or "rise", otherwise it would be a piecewise function and not a linear function. The equation y = 9 basically means that no matter what x is, y will always be 9.

Answer:

y = 9

Step-by-step explanation:

First find the slope of the line.  As we go from (-2, 9) to (15, 9), x increases by 17 but y does not change at all.  Thus the line is y = 9, good for all x values.

Hey There!!

The answer to this is: The building would be 100ft tall. You have to take 20/6 = ?/30 The difference between 6 and 30 is 5x. Then all you have to do is 20x5 and you get 100 ft.
