50 points find the area

Answer:

Step-by-step explanation:

Step 1 is to find the total number of balls in the pail.

There are 8 balls in total

Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.

Since 4 out of the 8 balls in the pail are green, you can write this as 4/8

The last step is to simplify to get 1/2 which in other terms is 50%.

So the probability of you pulling a green ball is 50%

Answer:

19657

Step-by-step explanation:

All of these quadratic equations are in vertex form, which makes it really easy to identify the vertex.

Vertex Form: f(x) = a(x - h)^2 + k

Vertex = (h, k)

As for the quadrants, it is dependent on the positive/negative signs of the x and y coordinates.

---Q1 = (+, +)

---Q2 = (-, +)

---Q3 = (-, -)

---Q4 = (+, -)

y = (x - 3)^2 - 2

Vertex = (3, -2)

Quadrant = Q4

y = (x - 3)^2 + 2

Vertex = (3, 2)

Quadrant = Q1

y = (x + 3)^2 + 2

Vertex = (-3, 2)

Quadrant = Q2

y = (x + 3)^2 - 2

Vertex = (-3, -2)

Quadrant = Q4

Answer:

alright so every person shook 7 people's hands so 7x and there are 7 people so 7(7) and that is 49

There are 21 handshakes happened.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

There are 7 people meet each other and each shake hands only once with each of the others.

Now,

We know that;

Number of handshakes = n (n - 1) / 2

Here, Number of people = 7

So, we can formulate;

Number of handshakes = n (n - 1) / 2

                                     = 7 (7 - 1) / 2

                                     = 7 × 6 / 2

                                     = 7 × 3

                                     = 21

Thus, There are 21 handshakes happened.

Answer:

(3/2 m)^2 -(5n)^2^

Step-by-step explanation:

Answer: 9m^2 / 4  -  25n^2

Step-by-step explanation:

Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

Answer:

x = 36°

Step-by-step explanation:

Sum of angles = 180°

66°+78°+x = 180°

144°+x = 180°

x = 180°-144°

x = 36°

Answer: y=-7

Step-by-step explanation:

solve 5x+2y =-4 for x

Add -2y to both sides

divide both sides by five
substitue -2/5y +-4/5 for x in 3X +10 Y equals -64

44/5 + -12/5 equals -64

Simply both sides

add 12/5 to both sides

Divided by 44/5
y= -7

Answer:

Hence The Value of Y=-2 at the intersecting point

Step-by-step explanation:

Given the equation

5x+2y=-4 and 3x+10y=-64

are intersected at X=2 to find the value of y

solution the equation 5x+2y=-4 and 3x+10y=-64

are intersect at x=2 means x=2 satisfied both equations so x=2 put in the

1st equation

5 x 2+2y=-4

2y=-4 -1 0= -14

y= -7

Answer:

Angle KGC or CGK

Step-by-step explanation:

In geometry, two angles are adjacent if they have a common side and a common vertex. In other words, adjacent angles are directly next to each other and do not overlap.

The value of theta in tanФ = 28/47 is 30.75° .

Given,

tanФ = 28/47

Here,

tanФ in right angled triangle measured by,

tanФ = P/B

P = perpendicular

B = base

Here,

tanФ = 28/47

Take inverse of tan to obtain the value of Ф .

Ф = \(tan^{-1}\) (28/47)

Ф = 30.75° .

If you climb up 5 flights of stairs will give zero. The correct option is D.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that situations can be represented with an integer​ that, when combined with the opposite of −5​, makes​ 0.

If you climb up 5 flights of stairs it will give the positive value of 5 when it is added to -5 then it will give zero.

Therefore, If you climb up 5 flights of stairs will give zero. The correct option is D.
