Answer:

16 girls

Step-by-step explanation:

boys : girls : total

5          4        5+4 = 9

take the total number of people and divide by 9

36/9 = 4

Each number should be multiplied by 4

boys : girls : total

5*4        4*4     9*4

20          16        36

There are 16 girls

Answer:

10010110

Step-by-step explanation:

A binary number is basically a number in base 2. So, each place represents a power of two. The ones place represents 1 or 2^0, the tens represents 2 or 2^1, the hundreds represents 4 or 2^2 and so on. To find the highest place needed to make in the number in binary, we find the greatest power of two that is below 150. In this case, it is 128. We can start by writing 128 in binary:

10000000

Now, we subtract 128 from 150 and find the largest power of two that is smaller than the difference. The largest power of 2 smaller than 22 is 16, so we put a one in the place for 2^4:

10010000

We can subtract 16 from 22 to get what is leftover to continue the process. We get 6, and the largest power of 2 smaller is 4. We can place a one in the hundreds place to represent it:

10010100

What is left is 6-4 or 2, which is just 2^1, so we can place it in the tens place:

10010110

Answer:

So, the difference is 44874.

Step-by-step explanation:

Multiplication of 4986 by 45

= 4986 x 45 = 224370

Multiplication of 4986 by 54

= 4986 x 54 = 269244

So, the difference in results is

= 269244 - 224370 = 44874

Answer:

7 coats (cups) of paint

Step-by-step explanation:

The dimensions of the room are;

The length of the room, l = 4 m

The width of the room, w = 3 m

The height of the room h = 2.5 m

The area one coat (taking the coat to mean cup) of paint can paint, A/c = 5 m²/cup

The total surface area of the room wall, A = 2 × l × h + 2 × w × h

∴ A = 2 × 4 m × 2.5 m + 2 × 3 m × 2.5 m = 35 m²

The amount of paint to be used, c = A/(A/c)

∴ c = 35 m²/(5 m²/cup) = 7 cups

The amount of paint to be used, c = 7 cups

Answer:

x = 8

Step-by-step explanation:

Given

3(x - 1) - 2(x - 1) = 7 ← distribute both parenthesis on left side

3x - 3 - 2x + 2 = 7 , simplifying

x - 1 = 7 ( add 1 to both sides )

x = 8

Step-by-step explanation: Scientific calculator helps.

Answer:

C

Step-by-step explanation:

I can get you the answer, but I do not know the proper method of deriving it out other than starting with y = 5 when x = 1 and go all the way up to x = 30 adding the result each time.

I might say that computer languages eat this for a pre breakfast meal. The solution is only five lines long.

Step-by-step explanation:

Since the triangles are similar we can use ratios to solve

4.5     7.5

---- = ------

3            x

Using cross products

4.5x = 3 * 7.5

4.5x = 22.5

Divide each side by 4.5

x = 22.5/4.5

x=5

Answer:

x-y=4

Answer:

32.7 degrees

Step-by-step explanation:

The total exterior angle of any polygon is 360 degrees

Each exterior angle can be calculated by dividing this total by the number of sides

So we have each measure as 360/n

where n is the number of sides

here, we have n = 11

So we have each exterior angle as:

360/11 = 32.7 degrees

[tex]a^{6}[/tex]

Step-by-step explanation:

Assuming you mean [tex]a^{5}[/tex] × a

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then

[tex]a^{5}[/tex] × a

= [tex]a^{5}[/tex] × [tex]a^{1}[/tex]

= [tex]a^{(5+1)}[/tex]

[tex]d = 0.3 t[/tex]

[tex]'d'[/tex] represents the distance travelled in meters

[tex]'t'[/tex] represents the time in minutes.

As per the given condition distance travelled in [tex]26.3[/tex] minutes is given by,

Step-by-step explanation:

coordinate point is (2 , 9)

translation rule is

(x , y) = (x + 3 , y - 8)

here x is 2 and y is 9

Answer:

C 8.9

Step-by-step explanation:

all these lines (from the same point of origin, cutting into and through a circle, ending at the far end of the circle they are cutting into) have the same relation of their lengths :

a×(a+b) is the same for all these lines.

with a being the first segment from the point of origin to touching the outside of the circle, and b being the length of the line inside the circle.

so,

4×(4+16) = 8×(8+2) = 80

this is correct for these two lines.

now, the line with the length x is a special case, as it does not really go through a circle, it only touches them.

but the length relation applies also to this line. it is just that the length inside the circle is 0.

so,

x×(x+0) = 80 (the same value as for the other lines)

must be true here too.

=>

x² = 80

x = sqrt(80) ≈ 8.9
