There are 5 green skittles, 4 orange skittles, and 3 red Skittles in a bag. What is the probability of red Skittle, Not replacing it (eating it), then picking a green skittle?​

Answers

Answer:

3/12

Step-by-step explanation:

the entire bag has 12 skittles. there are only 3 red. This gives a fraction of red skittles/entire bag in order to get the probability. So this would be 3/12 in this most basic sense? I am not sure if you need to go further than this or not. Hope this helps!

5x - y = -7
X + y = -5

Answers

Answer:

x = -2

y = -3

Step-by-step explanation:

5x - y = -7

x + y = -5

6x = -12

x = -2

x + y = -5

-2 + y = -5

y = -5 + 2

y = -3

Answer:

(-2,-3)

Step-by-step explanation:

x + y = -5

y = -x - 5

5x - (-x - 5) = -7

5x + x + 5 = -7

6x = -12

x = -2

x + y = -5

-2 + y = -5

y = -3

There were x cupcakes at the beginning of a party. By the end of the party, 16 of them had been eaten. Using x, write an expression for the number of cupcakes that were left.

Answers

Answer: x - 16

Step-by-step explanation:

Since there were x cupcakes at the beginning of a party and at the end of the party, 16 of them had been eaten, the expression for the number of cupcakes that were left will be gotten by subtracting the number of cupcake that have been eaten from the cupcakes at the beginning. This will be:

= x - 16

For example, if there were 20 cupcakes at the beginning and 16 was eaten, the number left will be:

= x - 16

= 20 - 16.

= 4

There'll be 4 left

The perimeter of ABCD is 26 cm

The area of PQRS is 45 cm(squares)
Find the length of AB

Answers

Area of rectangle= LxW
45cm2 divided by 10cm = 4.5cm
B-C= 4.5cm
Perimeter of rectangle= L+W x2
26/2 =13cm -4.5= 8.5cm
QR = 10cm and the area of that rectangle is 45cmsq so to work out PQ you do 45/10 = 4.5cm
PQ= 4.5cm

As BC = PQ they both equal 4.5cm

and the perimeter of ABCD is 26cm you so 26- (4.5x2) = 17
and 17/2 = 8.5cm

AB is 8.5cm

Answers

Answer:

3077.68

Step-by-step explanation:

the Area of the regular decagon is 3077.68

The area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

What is Area?

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write area -

V = ∫∫F(x, y) dx dy

Given is a regular decagon with length of each side is 20 units

The area of the regular decagon is -

A = (5/2)a²√(5 + 2√5)

We have {a} = 20. So, we can write that -

A = (5/2)(20)²√(5 + 2√5)

A = (5/2) x 400 x √(5 + 2√5)

A = 5 x 200 x √(5 + 2√5)

A = 1000√(5 + 2√5)

Therefore, the area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

Answer:

x = 15

Step-by-step explanation:

Since the quadrilateral is inscribed into circle, its opposite angles are supplementary:

m∠H + m∠K = 180°

Substitute the values and solve for x:

5x - 22 + 8x + 7 = 18013x - 15 = 18013x = 195x = 195/13x = 15

Answer:

Solution ::

According to the property of Cyclic Quadrilateral

5x - 22 + 8x + 7 = 180

(5x + 8x) - (22 - 7) = 180

13x - 15 = 180

13x = 180 + 15

13x = 195

x = 195/13

x = 15
