Answer:

162

Step-by-step explanation:

[tex] { \sqrt{xy} } = 3[/tex]

[tex] = > ( { \sqrt{xy} })^{2} = {3}^{2} [/tex]

[tex] = > xy = 9[/tex]

Also ,

[tex]x - y = 12[/tex]

[tex] = > {(x - y)}^{2} = {12}^{2} [/tex]

[tex] = > {x}^{2} + {y}^{2} - 2xy = 144[/tex]

Putting the value of 'xy' above gives :-

[tex] {x}^{2} + {y}^{2} - 2 \times 9 = 144[/tex]

[tex] = > {x}^{2} + {y}^{2} = 144 + 18 = 162[/tex]

Answer:

y = 9/2x -6.5

Step-by-step explanation:

m = (7-(-2))/(3-1)

m = 9/2

b = -6.5

y = 9/2x -6.5

Answer:

y = 8x+8

Step-by-step explanation:

We can solve for the function by finding the slope of the linear function using two points. Let's use (0,8) and (1,16)

Slope formula is: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

Plug in the 2 points: [tex]m = \frac{16-8}{1-0}[/tex]

Simplify: m = 8

So now, for the equation y = mx+b, we have m which is y = 8x+b

Now we need to find b by using another point from this linear function.

We can use the point (2,24).

Plug this point into the equation y = 8x+b

We have now found the equation of the linear function: y = 8x+8

Answer:

101cm

1000m= 1km,

When 1m is converted to km, it gives 0.001km=101mm.

Therefore the longest is 101cm because when we convert, we will get 1.1m.

Answer: 370,000

Step-by-step explanation:

712,350 - 342,802 round to the nearest ten thousands is 370,000.

Rounding is a process to estimate a particular number in a context.

To round a number look at the next digit in the right place, if the digit is less than 5, round down and if the digit is 5 or more than 5, roundup.

Now the given expression is,

712,350 - 342,802

Solving we get,

712,350 - 342,802 = 369,548

Now to round to the nearest ten thousands,

Digit at ten thousands is 6.

Digit to right of 6 is 9 which is greater than 5,

Thus round up the number.

So, we get 370,000.

Thus, 712,350 - 342,802 round to the nearest ten thousands is 370,000.

Answer:

There are 54 granola bars left.

Answer:

4.25

Step-by-step explanation:

Answer:

Step-by-step explanation: The answer of this question is functional because of the dilemma of fractions make it functional.

Answer: yes

Step-by-step explanation: I think that the least confusing way to do this problem is to first write down the ordered pairs that are represented by this mapping diagram.

So we have {(6, -1), (-1, 2), (4, 3), (0, 3)}.

In order for this relation to be a function, the x-coordinate can only

appear once unless we have the same ordered pair more than once.

Since each x-coordinate does appear once, it must be a function.

Students often make the mistake of saying this relation is not a function

because we have the same y-coordinate in two different ordered pairs, 3.

In other words, looking at the mapping diagram students will say that this relation is not a function because we have two x's paired with the same y.

Remember however that the definition of a function doesn't

say that each x must be paired with a different y.

It says that each x must be paired with exactly one y.

So in summary, a function can have the same y-coordinate in

two different points, just not the same x-coordinate.

The exception to this would be if the same ordered pair

is listed more than once in which it would be a function.

Step-by-step explanation:

Answer:

5-7 x = 2

Step-by-step explanation:

a number times negative seven added to five equals two

"a number times negative seven added to five equals two" is represented by expression 5-7x=2

An expression is combination of variables, numbers and operators.

The given sentence is "a number times negative seven added to five equals two"

Here let us consider the unknown number to be x.

As in the sentence we have a number times negative seven.

Times in the sentence means product. So the number x is multiplied with -7. i.e is -7x

Now a number times negative seven added to five.

This means 5 is added to -7x

-7x+5

"a number times negative seven added to five equals two" means -7x+5 is equal to two

-7x+5=2

5-7x=2

Hence the "a number times negative seven added to five equals two" is represented by expression 5-7x=2

Answer:

His second smoothie recipe

Step-by-step explanation:

Given that Victor has two receipts for smoothies:

The first recipe requires 2 strawberries to 7 cups of other ingredients (2:7),

The second recipe requires 3 strawberries to 9 cups of other ingredients, (3:9).

Let's crate a ratio tables in order to determine which recipe has more strawberry compared to other ingredients.

Ratio tables for first Recipe:

Straw berry | Other ingredients

2 | 7

4 | 2(7) = 14

6 | 3(7) = 21

Ratio Table for Second Recipe:

Straw berry | Other ingredients

3 | 9

6 | 2(9) = 18

9 | 3(9) = 27

Comparing his first recipe and his second recipe, when using 6 strawberries, his second recipe requires more cups of strawberry compared to other ingredients (6:18) than that required in his first recipe (6:21).

Answer:

[tex](x+6)^2+(y+\frac{7}{6})^2=\frac{49}{36}[/tex]

Step-by-step explanation:

So, we know that the center of the circle is at (-6, -7/6).

To find the equation of our circle that is tangent to the x-axis, we just need to find the vertical distance from our center to the x-axis.

Our center is at (-6, -7/6). The vertical distance from this to the x-axis directly above will be (-6, 0).

So, find our distance by subtracting our x-values:

[tex]d=r=0-(-7/6)[/tex]

Subtract:

[tex]d=r=7/6[/tex]

So, our distance, which is also our radius, will be 7/6.

Now, we can use the standard form for a circle, which is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where (h, k) is the center and r is the radius.

Substitute -6 for h, -7/6 for k, and 7/6 for r. This yields:

[tex](x+6)^2+(y+\frac{7}{6})^2=\frac{49}{36}[/tex]

Step-by-step explanation:

Answer:

1). a

2). b

3). c

4). d

Step-by-step explanation:

From the picture of a cone attached,

Radius of the circular top = r

Height of the cone = h

Slant height of the cone 'l' = 6

Area of the circular top of the cone with radius 'r' = πr²

Amount of space inside the cone = Volume of the cone = [tex]\frac{1}{2}\pi r^{2} h[/tex]

The amount of wrapper needed to cover the side of the ice cream cone, not including the circular top of the cone = πrl = πr(6 in.)

The vertical height 'h' of the cone when the cone is standing upright = [tex]\sqrt{6^2-r^2}[/tex]

[By Pythagoras theorem, l² = h² + r² ⇒ h = [tex]\sqrt{l^2-r^2}[/tex]]

The interquartile range is 5.

Given,

The data for the number of pounds of trash collected by each teenager is shown below.

26, 26, 21, 22, 20, 25, 35

We need to find the interquartile range

It is given by:

Q(3) = median of the upper half

Q(1) = median of the lower half.

Arrange in ascending order.

20, 21, 22, 25, 26, 26, 35

We have,

Lower half

Q(1) = 21

Upper half

Q(3) = 26

Interquartile range:

= Q(3) - Q(1)
