Total checkers = 2 + 6 = 8
P(black, then red) = (6/8)(2/7) = 3/14
Answer: 3/14
Your answer of 20% of 60 is 12
Answer:
2x - y = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 1 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 2) into the partial equation
2 = 2 + c ⇒ c = 2 - 2 = 0
y = 2x ← equation in slope- intercept form
Subtract y from both sides
0 = 2x - y , that is
2x - y = 0 ← equation in standard form
Answer:
Let the side of the cube be x.
Volume = length × width × height
For a cube:
Length = width = height
Now volume = x × x × x = x³
This equals 2197
Therefore :
X³ = 2197
X = ∛2197
= 13
The side of the cube = 13cm
Area = length × width
Length = width = 13cm
Area = 13 × 13 = 169
= 169 cm²
