90 * 0.1 = 9

Best of Luck!

Answer:

There are 9 boys

Step-by-step explanation:

Convert 10% into a decimal: 0.1

Multiply 0.1 by 90 = 9

Answer:

x=0

x=12

Step-by-step explanation:

Set up the equation

x^2-12x=0

Factor out x

x(x-12)=0

Set each factor equal to 0.

x=0

(x-12)=0

x=12

I think x = 31°

I solved it like this

x + 149 = 180

x = 180 - 149

x = 31 °

Answer:

  h = 3V/A

Step-by-step explanation:

Multiply by h to get it out of the denominator.

  Ah = 3V

Divide by the coefficient of h to get it by itself.

  h = 3V/A

_____

Whatever you do to one side of the equation must also be done to the other side. When we say "multiply by h", you should understand that to mean "multiply both sides of the equation by h."

This rule, "do the same thing to both sides of the equation," is the property of equality that makes Algebra work.

From the above statement we can assume an angle and its complement as x and (90° - x)

now, it's goven that the angle and it's complement are equal, so

i hope it helped...

Let the angle be x

You can re-write this quotient this way :

[tex]\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\[/tex]

What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))

In other word we must find x so that :

[tex]\frac{28(x-1)}{8x^{2}}\geq 0[/tex]

at the end we get

28(x-1) ≥ 0

28x - 28 ≥ 0

28x ≥ 28

x ≥ 1

So the answer is B, x ≥ 1

Answer:

r = 2

Step-by-step explanation:

Actually, there are 2 ways to solve this equation.

The first one:

5( 3r + 11) = 85

so here, you have to multiply 5 by ( 3r + 11) and maintain the 85

15r + 55 = 85... now put the like terms together. In other words, just transpose 55 to the other side.

15r = 85 -55..... remember that the sign of 55 will change from positive to negative

15r = 30.... now divide both sides by 15

15r/15 = 30/15

r = 2

The second method :

5 ( 3r + 11) = 85...... divide both sides by 5

5 (3r + 11) / 5 = 85/5

3r + 11 = 17

3 r = 17 - 11

3r = 6

r = 2

I hope this helps. If you don't quite get it, please go through until you get it. Have a nice day :-)

Answer:

r = 2

Step-by-step explanation:

5(3r + 11) = 85

~Use distributive property

15r + 55 = 85

~Subtract 55 to both sides

15r = 30

~Divide 15 to both sides

r = 2

Answer:

(-3.5,1.25)

Step-by-step explanation:

A is at -5,-4 and B is at -3,3

using the slope formula the slope has to be 3.5

meaning 3/4ths of the way is a translation of 1.5 right and 5.25 up making the coordinates (-3.5,1.25)
