➷ Work out the total number of cards (this will be the denominator for the fraction)

2 + 2 + 14  = 18

Probability of it being a red card: 2/18

Probability of it being a yellow card: 14/18

Add together these probabilities:

2/18 + 14/18 = 16/18

Simplify the fraction:

answer = 8/9

Your probability of a red is 2 out of 18.

Probability of a yellow is 14 out of 18.

Together it is 16 out of 18 or, in simplest form, 8/9.

Hope this is helpful!!

Answer:

5/hypotenuse, the square root of 7/ leg

Step-by-step explanation:

3^2+4^2=25 or 5^2. you use a^2+b^2=c^2. it would be one of the hypotenuses. If the missing number is a leg, you would do 4^2=3^2+x^2. 16=9+x^2, 7=x^2, so you plug in the numbers differently.

What is the value of x
goblinko [34]

Answer:

52/3

Step-by-step explanation:

Use basic Thales therom,

\frac{3x}{4x}=\frac{3x+7}{5x-8}\\\\\frac{3}{4}=\frac{3x+7}{5x-8}\\

Cross multiply,

3*(5x-8)=4*(3x+7)

3*5x - 3*8 = 4*3x + 4*7

15x - 24 = 12x +28

Add 24 to both sides

15x = 12x + 28 + 24

15x = 12x + 52

Subtract 12x from both sides

15x-12x =52

3x = 52

Divide both sides by 3

x = 52/3

Answer:

<u>Photo Lab:</u> y <u>=3.20x +8</u>

<u>Specialty Photos:</u> y <u>=2.60x + 10</u>

Step-by-step explanation:

At the Photo Lab, the cost is $3.20 per roll plus 8 per print.

Therefore, the cost of developing a roll of film is:

y <u>=3.20x +8</u>

At Specialty Photos the cost is $2.60 per roll plus 10 per print.

Therefore, the cost of developing a roll of film is:

y <u>=2.60x + 10</u>

Calculate the shaded area
Anton [14]
----------------------------------------------------------------
Find Radius :
----------------------------------------------------------------
Radius of the semicircle = 10 ÷ 2 = 5cm

----------------------------------------------------------------
Find Area of the semi circle :
----------------------------------------------------------------
Area of the semi circle = 1/2 πr²
Area of the semi circle = 1/2 x π x (5)²
Area of the semi circle = 12.5π cm²

----------------------------------------------------------------
Find Radius :
----------------------------------------------------------------
Radius of the inner circle = 5 ÷ 2 = 2.5 cm

----------------------------------------------------------------
Find area of inner circle :
----------------------------------------------------------------
Area of the inner circle = πr²
Area of the inner circle = π x (2.5)²
Area of the inner circle = 6.25π

----------------------------------------------------------------
Area of the shaded region :
----------------------------------------------------------------
Area of the shaded region = 12.5π - 6.25π
Area of the shaded region = 6.25π
Area of the shaded region = 19.63 cm²

----------------------------------------------------------------
Answer: Area of the shaded region = 19.63 cm²
----------------------------------------------------------------
