Answer:

  x = √(w(w+z))

Step-by-step explanation:

The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.

  BC/AC = DC/BC . . . . . short side/hypotenuse

  BC² = AC·DC . . . . . . cross multiply

  x² = (w+z)w . . . . . . substitute letter values

Taking the square root and rearranging to the form of the applicable answer choice, this is ...

  [tex]\boxed{x=\sqrt{w(w+z)}}[/tex]

Answer:

There is no graph.

Step-by-step explanation:

Answer:

1:0.06

Step-by-step explanation:

since there is a 6% sales tax, which is the same as 0.06. to calculate your tax, you would multiply both of the sides of the ratio by 75, and the left side will show you subtotal of what you are buying, the right will show tax.

Answer:

52%

Step-by-step explanation:

The entire shape if 25 squares, the shaded area if 13 squares. Set it up as 13/25 to get a decimal, 0.52. Move the decimal place two over to convert to a percentage, 52%

Answer:

NO Slope

Step-by-step explanation:

slope of the line passing through the points (5, 4) and (5, -5)

slope = y2 - y1   =    -5 - 4   = -9

            x2 - x1           5 - 5          0

see attached.

in this graph of a line x = 5, no matter what the value of y is.

the horizontal change is 0 and the vertical change is any y value

therefore, there is NO Slope

Answer:

H. the number of orchestra seat is 900

Step-by-step explanation:

Step one:

let the number of orchestra seat be x

and balcony seat be y

cost of orchestra= $50 each

cost of balcony =$40 each

total tickets= 1500

x+y= 1500----------1

amount earned= $69000

50x+40y=69000--------2

The system of equation for the situation is

x+y= 1500----------1

50x+40y=69000--------2

from 1, x=1500-y

put this in equation 2

50(1500-y)+40y=69000

75000-50y+40y=69000

-10y=69000-75000

-10y=-6000

divide both sides by -10

y=-6000/-10

y=600

put y= 600 in equation 1

x+600= 1500

x=1500-600

x=900

Answer:

15students per 1 teacher

9 student per 1 tutor.

8 tutors for 72 students

Step-by-step explanation:

From the question, arts academy requires there to be 4 teachers for every 60 students and 3 tutors for every 27 students

✓ 4 teachers for every 60 students

4teacher =60students

Then divide both sides by 4 , i.e (60/4)=15. Which means for every 1 teacher there is 15 students, hence we need 15students per 1 teacher.

✓3 tutors for every 27 students,

3 tutors = 27 students then divide both side by "3" (27/3)= which means we need 9 student per 1 tutor.

How many students does the academy have

per​ teacher?

15students per 1 teacher

Per​ tutor?

9 student per 1 tutor.

How many tutors does the academy need if it has 72 students​?

Since we need 9 student per 1 tutor., Then to know the numbers of tutor with 72 students,

9 student = 1 tutor.

72 students​= X tutor

If we cross multiply we have

72=9X

X=8 tutors

Therefore, we need 8 tutors for 72 students​

Answer:

No Solution

Step-by-step explanation:

6 - 3x = 4 - x - 3 - 2x  (Given)

6 - 3x = -1 -3x (combine like terms)

7 (addition)

The x cancels each other out so no solution.

Step-by-step explanation:

Answer:

The price of each latte was $4.5.

Step-by-step explanation:

6x + 18 = 45

6x = 45 - 18

6x = 27

x = 27/6

x = 4.5

The variable represents the cost of each latte.

Option (4)

Step-by-step explanation:

Domain of a function is a set of x-values (Input values) of the function.

For the given graph of square root function,

x - values starts from x = 0 and tends to x = ∞

Therefore, domain of the function will be,

x ≥ 0

Option (4) will be the correct option.

Answer:

y = [tex]\frac{n}{K - m}[/tex]

Step-by-step explanation:

When doing problems like these, you should go through the process like using PEMDAS:

P - Parenthesis ()

E - Exponents [tex]x^{2}[/tex]

M - Multiply x

D - Division ÷

A - Addition +

S - Subtraction -

1) Since there aren't any Parentheses, or exponents, we should then check for any use of Multiplication.

As shown, there are no shown methods of multiplying.

BUT there is Division, so we will do the opposite of division, which is multiplication.

K = m - n ÷ y

y(K = m - n ÷ y)y

^ Trying to multiply 'y' onto both sides, because when you do something to one side, you do to the other. ^

'y' then cancels out on one side, so you will be left with:

= m - n

But on the other side you will have:

Ky

So your problem will look like:

Ky = m - n

2) Since we are trying to get 'y' by itself, instead of multiplying now, we will be dividing, because:

K(y) = Ky  or you can also say K x y = Ky

Back to the problem, we will now divide 'K' to both sides, as stated before:

What you do to one side, you do to the other:

[tex]\frac{Ky}{K} = \frac{m - n}{K}[/tex]

'K' will cancel out on one side:

[tex]\frac{Ky}{K} = y[/tex]

Leaving you with:

'y'

While the other side, will be left as:

[tex]\frac{m - n}{K}[/tex]

So your final answer will be:

[tex]y=\frac{m - n}{K}[/tex]

x/r - s = t

Add s to both sides.

x/r - s + s = s + t

x/r + 0 = s + t

x/r = s + t

Multiply both sides by r.

r(x/r) = r(s + t)

x = r(s + t)

Understand?

Answer:

x=tr/s

Step-by-step explanation:

x/r-s=t

x-s=t×r

x-s/s=tr/s

x=tr/s
