colors and each show a number.
• The probability of randomly selecting a black card is.
• The probability of randomly selecting a red card is.
If Cathy randomly selects a card, what is the probability that her card is
black OR red?
Answer:
something missing here... is this a regular deck of cards Hearts, spades, clubs , and diamonds ? 1/2 red and 1/2 black ... if so....
then.....

Solve for W.
4w=5.12

Step-by-step explanation:
4w=5.12
Divide each side by 4
4w/4 = 5.12/4
x =1.28
8a=4(a-9)
Show work I need help
Answer:
a = -9
Step-by-step explanation:
8a=4(a-9)
Divide each side by 4
8a/4=4(a-9)/4
2a = a-9
Subtract a from each side
2a-a = a-9-a
a = -9
Answer:
-9
Step-by-step explanation:
8a = 4(a-9)
Use the distributive property (Multiply 4 times a, and 4 times -9)
8a = 4a - 36
Bring the 4a to the other side
8a - 4a = -36
Add like terms
4a = -36
Divide both sides by 4 to get a by itself
a = -9
If b is the midpoint of ac
Ab = 2x and ac = 5x + 8
Find bc
Answer:
3x+8
Step-by-step explanation:
2x+bc=5x+8
bc=5x-2x+8
bc=3x+8
find the HCF
eg. first expression = 4a -8
=4(a-2)
Answer:
Step-by-step explanation:
ab² + 2a²b + a³ = a(b² + 2ab + a²)
Here variable 'a' is common in all the terms. HCF = a
2) 2ab² = 2 * a * b *b
4a²b = 2 * 2 *a * a * b
6a³ = 2 * 3 * a * a * a
HCF = 2a
2ab² - 4a²b - 6a³ = 2a(b² - 2ab - 3a²)
A rectangle has a height of 5% and a width of 2 + 2.
Express the area of the entire rectangle.
Expression should be expanded.

w
5.2
Answer:
A rectangle has a height of 5 and a width of x² + 2
To find out:
Express the area of the emotive rectangle?
Formula used:
Area of rectangle = Length × Breadth.
Solutions:
Length = 5 and Breadth = x² + 2
We know that:
Area of rectangle = Length × Breadth.
Substitution the value of Length × Breadth.
= 5 × (x² + 2)
= 5x² + 10
Hence, the area of the emotive rectangle is 5x² + 10

• Binomial: expressions with two terms are called binomials.
• Trinomial: expressions with 3 terms is called trinomial.
• Multinational: expression with Tu are mo terms are called Multinational.

The line passing through points (5,) and (2,−3) is parallel to a line with a slope of 4/3. What is the value of y?
Answer:
Step-by-step explanation:
Parallel lines have same slope
Slope = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\dfrac{-3-y}{2-5}=\dfrac{4}{3}\\\\\\\dfrac{-3-y}{-3}=\dfrac{4}{3}\\\\\\-3-y=\dfrac{4}{3}*(-3)\\\\\\[/tex]
-3-y = 4*(-1)
-3 - y = -4
- y = - 4 + 3
-y = -1
Divide both sides by (-1)
y = 1

Find the probability of “landing” in the shaded region of the figures below. Round your answer to the nearest hundredth.
Answer:
#4Area of rectangle:
A = lw = 10*20 = 200 m²Shaded area:
A = 2πr² = 2π(10/2)² = 157.079 m²Probability:
P = 157.079/200 ≈ 0.785 or 78.5%#5Area of bigger circle:
A = πr² = π(20)² = 1256.637 m²Shaded area:
A = π(10² - 5²) = 235.619 m²Probability:
P = 235.619/1256.637 ≈ 0.187 or 18.7%Answer:
4
We know that
Area of rectangle = lb
Area = 10(20)
Area = 200 m²
Shaded region = πr²
=> 2 × 22/7 × (10/2)²
=> 2 × 22/7 × 10/4
=> 157 m²
Probability = 157/200 = 78.5%
5.
Area of the biggest circle = πr²
= 22/7 × (20)²
= 1256.6
Area of shaded region
π(10² - 5²)
π(100 - 25)
3.14(75)
235.6
Probability = 235.6/1256.6 = 18.7%
Select all expressions that are equivalent to x2 - 4x - 32.
(x - 16)(x + 2)
(x + 2)(x - 16)
(x - 8)(x + 4)
(30+8)(x – 4)
(x + 4)(x - 8)
(x – 4)(x + 8)
Answer:
(x - 8)(x + 4)
(x + 4)(x - 8)
Step-by-step explanation:
(x - 16)(x + 2)
= x2 + 2x - 16x - 32
= x2 - 14x - 32
(x + 2)(x - 16)
= x2 - 16x + 2x - 32
= x2 - 14x - 32
(x - 8)(x + 4)
x - 8)(x + 4) = x2 + 4x - 8x - 32
x - 8)(x + 4) = x2 + 4x - 8x - 32 = x2 - 4x - 32
( 30 + x)(x - 4)
= 30x - 120 + x2 - 4x
= x2 + 26x - 120
(x + 4)(x - 8)
(x + 4)(x - 8) = x2 - 8x + 4x - 32
(x + 4)(x - 8) = x2 - 8x + 4x - 32 = x2 - 4x - 32
(x - 4)(x + 8)
= x2 + 8x - 4x - 32
= x2 + 4x - 32

Answer:
GI=15
Step-by-step explanation:
GI=HI+GH
GI=12+3= 15
I hope I helped you^_^
Hi! I'm happy to help.
To solve this we need to know what is happening. This line segment was split into two parts by H. GH (part 1) and HI (part 2).
These two parts together equal the total length of the line segment. We learn that GH is 3, and HI is 12.
12+3=15
Now, we know that GI has a length of 15.
I hope this was helpful, keep learning! :D
