Answer:

x = [tex]\frac{ 7\sqrt{3} }{3}[/tex]

Step-by-step explanation:

7 = [tex]x\sqrt{3}[/tex]

x = [tex]\frac{7}{\sqrt{3}}[/tex]

multiply numerator and denominator by [tex]\sqrt{3}[/tex]

x = [tex]\frac{ 7\sqrt{3} }{3}[/tex]

Answer:

Jersey cost (without discount)= $65

Step-by-step explanation:

First, we need to determine how much he spent on the jersey:

Jersey cost (with discount)= 83.39 - 37.89

Jersey cost (with discount)= $45.5

Now, the original cost of the jersey:

Jersey cost (without discount)= discount cost / (1 - discount)

Jersey cost (without discount)= 45.5 / 0.7

Jersey cost (without discount)= $65

Hi! So what you will need to know is pythagorean theorm.

What the theorm basically says is a^2 + b^2 = c^2.

-- The (a,b,c) are referring to the sides of the triangles (3 letters for 3 sides).

Take note that "c" is always the side opposite of the right angle.

The other known side could be "a" or "b"

Taking a look at problem 9, identify the "c" value. The "c" value would be 35.

Then indentify the value of "b" or "a". "a" would = 20.

Plug it into the equation:

20^2 + b^2 = 35^2

400 + b^2 = 1225

solve for b.

1. subtract 400 from both sides.

b^2 = 825

b = [tex]\sqrt{825}[/tex]

you could solve for the square root but it would give a decimal numbers but I'm not sure what the teacher is looking for.

$360.00

Step-by-step explanation:

$13.00 + $10.00 + $30.00 + $100.00 + $100.00 + $100.00 + $7.00 = $360.00

I hope this helps you :D

Answer:

(x-5)(x-5)

Step-by-step explanation:

x^2-10x+25=0

(x-5)(x-5)

since:

-5-5=-10

and

-5×-5=25

hope this makes sense :)

Answer:

f(x) = (1/3)x - 2  

f(x) = (1/3)(3) - 2  

f(x) = 1 - 2  = -1

Step-by-step explanation:

f(x) usually refers to a function not a multiplication of two variables

Answer:

72.18

Step-by-step explanation:

The hundreth place is the second to the right of the decimal. So the number in the hundreths place is 72.178. When rounding, you look at the number behind the number you are rounding to. In this case, you want to look at the 8. If the number is 5 or above, you round up. 8 is above 5 so you round the 7 to an 8.

Answer: 72.18

Step-by-step explanation:

hope this helps

Answer:

2/7

Step-by-step explanation:

because 14 can be reduced to 7and 4 can be reduced to 2

Answer: (C) 2/7

Step-by-step explanation: 2/7 is the same as 4/14

Answer:

window sill height =9.75 meters

Step-by-step explanation:

Ladder^2=height^2+length^2

12^2=height^2+7^2

144=height^2+49

height^2=144-49=95

height=9.75

Answer:

CD = 4

Step-by-step explanation:

I believe you know the geometric mean for altitudes?

CD = √AD * DB = √8 * 2 = √16 = 4

If you are not aware of this theorem, then use the similarity of triangles.

ADC ~ CDB

AD/DC = CD/DB (cross-multiply)

CD^2 = AD*DB,

CD = √AD * DB = √8 * 2 = √16 = 4

Answer:

Step-by-step explanation:

Alright all we need to know is to understand our brackets

So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}​

3+20-5-9+4-3(1-5)

Step 2

3+20-5-9+4-3(1-5)  Simplify

18-9+4-3(1-5)

Step 3

18-9+4-3(1-5)

13-3(1-5)

13-(-12) Here is the tricky part (We aren't going to subtract because the brackets multiply the equations

So,

13+12=25

Your answer is 25

Answer:

x=-24

Step-by-step explanation:

Multiply both sides by 4 to get x=-24

[tex]\\ \rm\hookrightarrow -6=\dfrac{x}{4}[/tex]

Multiply 4 on both sides

[tex]\\ \rm\hookrightarrow x=-6(4)[/tex]

[tex]\\ \rm\hookrightarrow x=-24[/tex]

Answer:

11 1 /2 ( 11 and a half)

Step-by-step explanation:

If you noticed 7 and 2 are five numbers away.

To solve this I just added one to both of them until the sum was equal to 28.

If I had added one to 16 and 11, it would have given me 29, so I added a half.

That gave me 28.

Answer:

Number is 4536

Step-by-step explanation:

Assume;

Same number = a

Multiply of 7 = b

So,

a+a+a+b = 39

3a + b = 39

Use b = 7

3a + b = 39

3a + 7 = 39 (Not possible)

Use b = 14

3a + b = 39

3a + 14 = 39 (Not possible)

Use b = 21

3a + b = 39

3a + 21 = 39

a = 6

So,

Number is 6 x 6 x 6 x 21

Number is 4536

Answer:

option (3)

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = x² - 12x + 7

Using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 12x

f(x) = x² + 2(- 6)x + 36 - 36 + 7

      = (x - 6)² - 29

with vertex (h, k ) = (6, - 29 )

Answer:

  a)  x = ±5

  b)  x = ±√11 ≈ ±3.317

Step-by-step explanation:

Since we want x for some function value, it is convenient to determine the inverse function.

  x = g(y)

  x = y^2 -5

  x +5 = y^2

  y = ±√(x +5)

__

a) x = ±√(20 +5) = ±5

b) x = ±√(6 +5) = ±√11 ≈ ±3.317
