If there are 20 girls and 30 boys what is the percentage of boys

Answer:

The answer is Zero.

Step-by-step explanation:

Adding a negitive 5 to a positive 5 cancels out

Answer:

0

Step-by-step explanation:

It's a negative five, meaning that if you are adding it, the number will still go back.

You made $5, but you're in debt of $5. So even though it is supposed to go up, it goes down back to 0 due to the debt, which is the negative.

Answer:

KL = 27

JK = 16

MK = 30

NL = 23

m∠JKL = 132°

m∠KLJ = 22°

m∠KMJ = 54°

m∠KJL = 26°

Step-by-step explanation:

The given parameters of the quadrilateral JKLM are;

JM = 27, ML = 16, JL = 46, NK = 15, KLM = 48, JKM = 78, MJL = 22

Taking the sides as parallel, we have that quadrilateral JKLM is a parallelogram

Therefore;

KL = JM = 27

JK = ML = 16

m∠KLJ = m∠MJL = 22°

MN = NK = 15

MK = MN + NK = 15 + 15 = 30

NL = JL/2 = 46/2 = 23

m∠KJM = m∠KLM = 48°

m∠KJL = m∠KLM - m∠MJL = 48° - 22° = 26°

m∠KML = m∠JKM = 78°

m∠MKL = 180° - m∠KML - m∠KLM = 180° - 78° - 48° = 54°

m∠MKL = 54°

m∠JKL = m∠JKM + m∠MKL = 78° + 54° = 132°

m∠KMJ = m∠MKL = 54°

Applying the properties of a parallelogram, the missing values are:

KL = 27; JK = 16; MK = 30; NL = 23

m∠JKL = 132°; m∠KLJ = 22°; m∠KMJ = 54°; m∠KJL = 26°

Applying the properties of a parallelogram, we will find the given measures as follows:

KL = JM  (congruent sides)

KL = 27

JK = ML (congruent sides)

JK = 16

MK = 2(NK)

Substitute

MK = 2(15)

MK = 30

NL = 1/2(JL)

NL = 1/2(46)

NL = 23

m∠JKL = 180 - m∠KLM (supplementary angles)

m∠JKL = 180 - 48

m∠JKL = 132°

m∠KLJ = m∠MJL (congruent angles)

m∠KLJ = 22°

m∠KMJ = m∠MKL (congruent angles)

m∠MKL = 180° - 78° - 48° = 54°

m∠KMJ = m∠MKL = 54°

m∠KMJ = 54°

m∠KJL = 48° - 22°

m∠KJL = 26°

Step-by-step explanation:

We have,

a ^2 −(b−c) ^2

Since, x ^2 −y ^2 =(x+y)(x−y)

Thus,

⇒[a−(b−c)][a+(b−c)]

⇒(a−b+c)(a+b−c)

Answer:

h(x) = - (x + 5)³

Step-by-step explanation:

From the graph attached,

Function 'h' is the transformed form of function 'g',

If function 'g' is shifted by k units to the left, the new function 'h' will be,

h(x) = g(x + k)

As shown in the graph,

Function 'g' has been shifted by 6 units to the left,

h(x) = g(x + 6)

h(x) = - [(x + 6) - 1]³

h(x) = - (x + 5)³

Answer:

5 1/4 cubes

Step-by-step explanation:

Volume of the cubical box = length × width × height

= 6 in x 3 in × 7 in

= 126 in³

Volume of the cube = length × width × height

= 3 in x 4 in x 2 in

= 24 in³

how many cubes with the dimensions of 3 in x 4 in x 2 in can be fitted into the cubical box

= Volume of cubical box / Volume of the cube

= 126 in³ / 24 in³

= 5 1/4 cubes

Horizontal goes from left to right. Therefore, the horizontal axis would be the x-axis because it shows the shifts from left to right. The y-axis would be up and down, which is vertical.

Answer:

y = - x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

4x + 4y = - 32 ( subtract 4x from both sides )

4y = - 4x - 32 ( divide all terms by 4 )

y = - x - 8 ← in slope- intercept form

Answer:

x+y=-8

Step-by-step explanation:

-32=4x+4y

-4y=4x+32

y=(4x+32)/-4

y=-x-8

x+y=-8

Now comparing to slope intercept form

y=mx+c,we get

slope =1

y intercept =1

y=-8

Step-by-step explanation:

Answer:

Hi, let's turn the word problem into a set of equations:

Let's say that x = # of chickens, and y = # of pigs

If there are 13 animals altogether, that means that

x + y = 13

If there are 40 legs together, we know that chickens have 2 legs, while pigs have 4, so the total number of legs would be:

2x + 4y = 40

We now have two different equations, with the same two variables, so we can rearrange and substitute one equation into the other to solve. We can rearrange the first equation as:

x + y = 13

x = 13 - y

Let's plug this expression for "x" into the second equation:

2(13-y) + 4y = 40

Now we have an equation with only one variable, so we can use algebra to solve for y:

26 - 2y + 4y = 40

2y = 14

y = 7, there must be 7 pigs.

From the first equation that we rearranged,

x = 13 - y

Now that we know the numerical value of "y", we can plug that in:

x = 13 - 7

x = 6, there must be 6 chickens

Answer:

4metres

Step-by-step explanation:

Given the height of the trail modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers

The horizontal distance occurs at the x intercept i.e at h(x) = 0

Substitute

0 = -0.1x^2 - 0.3x +2.8 ,

Multiply through by -10

0 = x^2 + 3x - 28

x^2 + 3x - 28 = 0

Factorize

x^2 + 7x - 4x - 28 = 0

x(x+7) - 4 (x+7) = 0

(x-4)(x+7) = 0

x-4 = 0 and x+7 = 0

x = 4 and -7

Since the danced cannot be negative, hence the horizontal distance of the trail is 4m
