Answer:

A. Black Dogs

Step-by-step explanation:

it cant be any other one because it says for every brown dog there are 2 of a different dog. So there are 5 brown dogs so that means there is going to be ten of another kind and that is the black dogs.

The formula for the discriminant is

d = b^2 - 4ac

If d < 0, then there are no real number solutions

If d = 0, then you have exactly one real solution

If d > 0, then you have two different real number solutions

Answer:

x =  9(a+g)

Step-by-step explanation:

x/9 - g = a

Add g to each side

x/9 - g+g = a+g

x/9 = a+g

Multiply each side by 9

x/9 * 9 = 9(a+g)

x =  9(a+g)

The equation of the parallel line that passes through the point (-2, 2) is y= (1/5) x + (12/5)

Therefore,

The slopes of the two lines will be the same because it runs parallel to the line predicted by the equation.

The slope of the line is 1/5,

We know that the line is y= (1/5) x + c.

We can now find the y-intercept using the given point (-2,2).

[tex]$&\Rightarrow y=m x+c \\[/tex]

[tex]&y^2=\frac{1}{5}(-2)+c \\[/tex]

[tex]&\Rightarrow^2=\frac{-2}{5}+c \\[/tex]

[tex]&\Rightarrow c=2+\frac{2}{5}=\frac{10+2}{5}=\frac{12}{5} \\[/tex]

[tex]&\Rightarrow c=\frac{12}{5}[/tex]

Hence, The line's final equation will be [tex]y=\frac{1}{5} x+\frac{12}{5}[/tex]

Answer:

7 1/2

Step-by-step explanation:

Let's add the whole numbers first, 3 + 4 = 7

Then, we add the fraction, and since the denominator is the same, there's no need for a change, so we just add the top. 1/8 + 3/8 is 4/8, which can be simplified to 1/2

so answer is 7 1/2

Step-by-step explanation: daddy for ever

Let me know if you want the answer, but what you need to do first is get the opposite angles.

They're on straight lines, so 180 minus that angle would equal the angle inside the triangle.

Then all inner angles if a triangle add up to 180° so 180 minus the two other angle would give you the final missing angle.

Do the straight line thing again and subtract 156 from it.

Answer:

Volume of box is [tex]432 in^3[/tex]

Step-by-step explanation:

Let x be the side of square corner

Length of box after cutting corners =22-2x

Breadth of box after cutting corners =15-2x

Height =x

Volume of box = (22-2x)(15-2x)x

Volume of box =[tex]4x^3-74x^2+330x[/tex]

Differentiate w.r.t x

[tex]\frac{dV}{dx}=12x^2-148x+330[/tex]

Substitute derivative =0

[tex]12x^2-148x+330=0\\x=\frac{37-\sqrt{379}}{6},\frac{37+\sqrt{379}}{6}\\\frac{d^2V}{dx^2}=24x-148[/tex]

at [tex]x=\frac{37-\sqrt{379}}{6}[/tex]

[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37-\sqrt{379}}{6} )-148=-77.87 < 0[/tex] hence maximum

at  [tex]x=\frac{37+\sqrt{379}}{6}[/tex]

[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37+\sqrt{379}}{6} )-148=77.87>0[/tex] hence minimum

So,Volume of box =[tex]4x^3-74x^2+330x=4(\frac{37-\sqrt{379}}{6} )^3-74(\frac{37-\sqrt{379}}{6} )^2+330(\frac{37-\sqrt{379}}{6} )=432.23 in^3[/tex]

Hence Volume of box is [tex]432 in^3[/tex]

Answer: 0.23

Step-by-step explanation:

Given that:

Percentage population of males = 77% = 0.77

Hence,

Percentage that aren't male = ( 1 - 0.77) = 0.23

P(males) = 0.77

Hence,

P(non-males) = 1 - 0.77 = 0.23

Answer:

Step-by-step explanation:

Use the diagram in the attachment for reference. You can substitute the values given in question in place of the one in the diagram.

From the diagram, it can be seen that the sum of angle x and 20 is equal to angle 75 degrees i.e x+30 = 75 (alternate angles)

Next is to find the value of x from the equation

x+30 = 75

Subtract 30 from both sides of the equation;  

x+30-30 = 75-30

x = 75-30

x = 45

Hence the measure of angle x is 45°

Answer:

The answer is 45
