There are 3 times as many boys as girls. If there are 24 more boys than girls, how many children are there?
Ludmilka [50]

Answer:

There are 48 children.

Step-by-step explanation:

Given :There are 3 times as many boys as girls.

            There are 24 more boys than girls,

To Find : how many children are there?

Solution:

Let the number of girls be x

Now we are given that there are 3 times as many boys as girls.

So, no. of boys = 3x

Now we are given that there are 24 more boys than girls.

So, 3x-x=24

2x=24

x=12

So, no. of girls = 12

No. of boys = 3x = 3(12) = 36

Now the total no. of children = 12+36 = 48

Hence there are 48 children.

Point N(7, 4) is translated 5 units up.
lutik1710 [3]

It is given in the question that

Point N(7, 4) is translated 5 units up.

And we have to find the coordinates of its image after this transformation.

Since the point translated up by 5 units, so the x coordinate remains same and we have to add 5 to y coordinate.

So the new coordinate after the transformation is

N'(7+5,4)
\\
N'(12,4)

And that's the required coordinate  after the given transformation .

11 hours 18 min 36 sec to hours
zlopas [31]
I'm not really sure about this math but I tried to answer it for you

1)Convert 11 hours to minutes = 660 minutes. 11 hours x 60 mins=660
2)Add the 18 minutes to 660 =678 minutes
3) 678 divided by 60 mins = 11.3 hours, but we still have the 36 seconds remaining so I didn't exactly divide 678 minutes by 60, but I divided 678.36 by 60 which gave me 11.306 hours.

That's it I truly apologise if this is wrong. But if you figure out the right method please show me and others who may have done it this way or another way, so please share. GOOD LUCK.

the equation of a circle in general form is x squared + y squared + 20x + 12 y + 15 equals 0what is the equation of the circle i
Marrrta [24]

Answer: (x+10)^2+(y+6)^2=121

Step-by-step explanation:

The equation of a circle in the general form is:

 ax^{2}+by^2+cx+dy+e=0

The equaton of  a circle in standard form is:

(x-h)^2+(y-k)^2=r^2

Where the center is at <em>(h, k)</em> and <em>r</em> is the radius

To write the equation of a circle from general form to standard form, you must complete the squaare, as you can see below:

1- Given the equation in general form:

x^{2}+y^2+20x+12y+15=0

2- Complete the square:

-Group the like terms and move the constant to the other side.

- Complete the square on the left side of the equation.

- Add the same value to the other side.

Then you obtain:

(x^{2}+20x)+(y^2+12y)=-15\\(x^2+20x+(\frac{20}{2})^2)+(y^2+12y+(\frac{12}{2})^2)=-15+(\frac{20}{2})^2+(\frac{12}{2})^2\\\\(x+10)^2+(y+6)^2=-15+100+36\\(x+10)^2+(y+6)^2=121
