Step-by-step explanation:

Angles on the same side of the transversal are equal.

Answer:

x=40

Step-by-step explanation:

If m and n are parallel (symbol ||) then the blue angles must be equal.

In other words, 120 must be 3x.

Hence the solution for x is 120 divided by 3, which is 40.

What value of b will cause 16x ^ 2 + bx + 4 = 0 to have one real solution ?

Answers

Answer:

b  =  16

Step-by-step explanation:

16*x  + b*x  + 4  =  0

Solving for x we get:

x₁,₂  =   - b  ±  √  b² - 4*a*c   ] / 2*a         (1)

If we take a look to the square root

√ b² - 4*4*16      =  √ b²  - 256

if we make √ b²  - 256    = 0

b²  =  256       ⇒      b  =  16

Then equation (1) becomes:

x₁,₂  = ( - 16  ±  0  ) / 32

x  = -  1/2

This is 8th grade math 5y+2×5h=4h Solve for h

Answers

Answer:

h= −5/6y (negative 5 y over 6)

Step-by-step explanation:

5y+(2)(5)h=4h

Step 1: Add -4h to both sides.

10h+5y+−4h=4h+−4h

6h+5y=0

Step 2: Add -5y to both sides.

6h+5y+−5y=0+−5y

6h=−5y

Step 3: Divide both sides by 6.

6h/6=−5y/6

h=−5/6y

Answer:

h = - 5y/ 6

Step-by-step explanation:

5y + 2 * 5h = 4h

Using BODMAS

Perform multiplication first

5y + 10h = 4h

Collect like terms

5y = 4h - 10h

5y = - 6h

Divide both sides by - 6

5y / - 6 = - 6h / - 6

h = - 5y/ 6

The total distance around Regina rectangular shaped bedroom is 300 feet, the length of the room is 80 feet. What is the area of Regina bedroom

Answers

Answer:

5600 square feets

Step-by-step explanation:

Let [tex]l, b[/tex] denote length and breadth of the rectangular shaped bedroom.

The total distance around Regina rectangular shaped bedroom is 300 feet.

[tex]2(l+b)=300\\l+b=150[/tex]

The length of the room is 80 feet.

Put [tex]l=80[/tex]

[tex]80+b=150[/tex]

[tex]b=150-80=70[/tex] feets

Area of the rectangular shaped bedroom [tex]=lb=80(70)=5600[/tex] square feets.

The length of the side of a square is 8 V12 in. What is the area of the square? es A) 16 V12 in? B) 64 V12 in? C) 384 in2 D) 768 in2
can you guys help this? thanks​

Answers

Answer:

D

Step-by-step explanation:

We are given that the side of a square is: 8√12.

And we want to find the area.

The area of a square is given by:

[tex]A=s^2[/tex]

Where s is the side length. Remember that all side lengths in a square are equivalent.

Therefore, by substitution, we acquire:

[tex]A=(8\sqrt{12})^2[/tex]

Evaluate. We can expand:

[tex]A=(8)^2(\sqrt{12})^2[/tex]

Simplify:

[tex]A=64(12)=768\text{ in}^2[/tex]

Hence, our final answer is D.

If the monthly cost for 14 HCF is $48.70, what is the monthly cost for 10 HCF?

Answers

Answer:

$34.78

Step-by-step explanation:

first,  we need to find the value of 1 HCF, so we divide $48.70 by 14, giving us the result of 3.47857143. (rounding that turns out to be 3.48.

next, we need to multiply the cost of 1 HCF by 10, so 3.48 * 10 = 34.78
