Solve for X and Z

Answer:

y = 5/7 x

y = 7/9 x

y = 3/4 x

Step-by-step explanation:

Firstly, let us get the unit rate on the table

That would be;

y/x = 2/3

y = (2/3)x

so the fractions greater than 2/3 will

be our answer

3/4 is greater

7/9 is greater

5/7 is greater

Answer: 1️⃣ 40

Step-by-step explanation:

x - is the side of the square

[tex]x^{2} +x^{2} =(10\sqrt{2})^{2} \\2x^{2}} =200\\2x^{2} \div 2=200 \div 2 \\x^{2} =100\\x=\sqrt{100} \\x=10 \: [cm] - side \: of \: a \: square[/tex]

Find the perimeter of the square.

Perimeter of the square = 4 × 10 cm = 40 cm

Answer:

7.21

Step-by-step explanation:

Solution,

Given,

base = 4

perpendicular = 6

hypotenuse = ?

Now,

By the formula of Pythagoras Theorem,

h^2 = p^2 + b^2

h^2 = 6^2+4^2

h^2 = 36+16

h = sqrt ( 52 )

h = 7.21

Therefore, the value of x (hypotenuse) is 7.21 .

Answer:

x= 7.21///no

Step-by-step explanation:

4^2 + 6^2 = 52

take the square root which equals 7.21

///

Pythagorean triples consist of perfect squares, like 2^2 is for the side that is equal to 4, 6 is not a perfect square.

Answer:

Here are a few ways that I do that:

18 * 5 is the same as (10 + 8) * 5, which equals 50 + 40, which is 90

It's also the same as (20 - 2) * 5, which equals 100 - 10, again, 90

It's also 9 * 2 * 5, which equals 9 * 10, or 90

It's also 3 * 6 * 5, or 3 * 30, which is 90.

Answer: $31.50

Step-by-step explanation:

We are told that the price of a baseball card was purchased for $6 but that the value of the baseball card has increased by 425%.

The current value of the baseball card would be:

= $6 + (425% × $6)

= $6 + (425/100 × $6)

= $6 + (4.25 × $6)

= $6 + $25.5

= $31.50

Answer:

  x = √70

Step-by-step explanation:

The right triangles are all similar, so we can write the ratio of long side to hypotenuse as ...

  x/(7+3) = 7/x

  x^2 = 7(10) = 70

  x = √70

_____

Additional comments

This is called a "geometric mean", where x is the square root of the product of two numbers, 7 and 10. Those happen to be the lengths of the adjacent segment of the hypotenuse and the whole hypotenuse.

The same relation holds for BC:

  BC = √(CD·CA)

__

A slightly different geometric mean relation holds for the altitude BD:

  BD = √(DC·DA)

Answer:

I am pretty sure its the first one

I would say the bottom right graph (D) best fits the data because it passes through the most points possible on the graph.

Answer:

B

Step-by-step explanation:

n+(n+1)=59

2n=59-1=58

n=58/2=29

n+1=29+1=30

Answer:

There is not a proportional relationship

Step-by-step explanation:

The first and second hour the pay is $9.50/hour, but in the third hour the pay is $11/hour. Then in the fourth hour it changes again to $10/hourIf there was a proportional relationship there would need to be a constant rate of change in pay.

Answer:

Yes, the proportional relationship is 9.50

Step-by-step explanation:

In the graph that you have attached this picture with, hours x 9.50 = pay.

Hope this helps :D

Answer:

They all have equal bases.

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

how are we suposed to do this

Answer:

194

Step-by-step explanation:

you would do 340 divided by 2 and that gets you 170 then you would subtract 24 from Rita and that is 146 so Rita drove 146 miles. then for Joel you add 170 +24 = 194. So Joel drove 194 miles.

Answer:

x = 6

x = -1

x = 1

Step-by-step explanation:

Given:

Correct equation;

P(x) = x³ - 6x² - x + 6

Computation:

x³ - 6x² - x + 6

x²(x-6)-1(x-6)

(x-6)(x²-1)

we know that;

a²-b² = (a+b)(a-b)

So,

(x-6)(x²-1)

(x-6)(x+1)(x-1)

So,

zeroes are;

x = 6

x = -1

x = 1

Answer:

The result of multiplying 7 with 8 is called the product. Thus, the product of 7 and 8 is as follows:

56

In other words, we find the product of 7 and 8 by simply calculating 7 times 8 which equals 56. Pretty easy huh?

If someone asks you, "What is the product of 7 and 8?", your answer will be:

7 x 8 = 56

To find any product in the future on your own, just remember that the product is the answer you get when you multiply numbers together.

Answer:

56

Step-by-step explanation:

Product means to multiply

7 * 8 = 56

Check...

56 / 7 = 8

56 / 8 = 7

Yes

Answer:

[tex]x=\sqrt{7},\:x=-\sqrt{7}[/tex]

Step-by-step explanation:

Start by rewriting the equation to standard form [tex]ax^2+bx+c=0[/tex].

[tex]5(x^2-10)+5=-10,\\5x^2-50+5=-10,\\5x^2-35=0[/tex].

Factor out the 5, then isolate [tex]x^2[/tex]:

[tex]5x^2-35=0,\\5(x^2-7)=0,\\x^2-7=0,\\x^2=7,\\x=\pm \sqrt{7}.[/tex].

Therefore, the solutions to this quadratic are:

[tex]x=\sqrt{7},\:x=-\sqrt{7}[/tex]

Answer:

Step-by-step explanation:

we have we know that see the graph

Let

Find the slope B   The slope is positive

so

The graph is increasing in the interval----------> (10, ∞)

Find the slope AB

The slope is negative

so

The graph is decreasing in the interval----------> (-∞,10)

therefore

Answer:

80 minutes

Step-by-step explanation:

Represent Plan A as y = $26.50 + ($0.35/min)x, where x is the number of minutes consumed.  

Represent Plan A as y = $42.50 + ($0.15/min)x

We set these two equations equal to one another and solve for x, the number of minutes at which the costs of the two plans are momentarily equal:

y = $26.50 + ($0.35/min)x = y = $42.50 + ($0.15/min)x

Combining like terms, we get:             ($0.20/min)x = $16.00

                  $16.00

Then x = -------------------- = 80 minutes

                 ($0.20/min)

Answer:

2

Step-by-step explanation:

Remark

You are going to set up a proportion. The sides used are opposite the chosen angles.

Givens

x is opposite an angle marked by 2 arcs.

5 is opposite an angle marked with 1 arc.

8 is opposite an angle marked with 2 arcs

20 is opposite an angle marked with 1 arc.

Equation

x/5 = 8/20              Cross Multiply

20x = 5*8

20x = 40

x = 40/20

x = 2

Answer:

4.2

Step-by-step explanation:

Hypotenuse ² = opposite ² + adjacent ²

Opposite = 3

Adjacent = 3

Hypotenuse ² = opposite ² + adjacent ²

Hypotenuse ² = 3² + 3²

Hypotenuse ² = 9 + 9

Hypotenuse ² = 18

Find the square root of both sides

√Hypotenuse² = √18

Hypotenuse = √18

Hypotenuse = 4.2426406871192

Hypotenuse = 4.2 to the nearest tenth

Answer:

[tex]\mathrm{D.\:}14<x<32[/tex]

Step-by-step explanation:

In any triangle, the sum of any two sides must be greater than the other side. Therefore, in the given triangle with side lengths [tex]9[/tex] and [tex]12[/tex], we can write the following inequalities:

[tex]\begin{cases}(x-2)+9>21,\\21+9>(x-2)\\\end{cases}[/tex]

Solving these inequalities, we get:

[tex]x-2>12,\\x>14\\\\30>x-2,\\x<32[/tex].

Combining this into one inequality gives us:

[tex]\mathrm{D.\:}14<x<32[/tex].
