Answer:
Bottom left/ 3rd one
Step-by-step explanation:
The correct answer would be the 3rd one. Since they don't have numbers, it would be the bottom left one. A coin can land on heads or tails so the answer as to be splits to heads or tails which then splits into heads or tails.
Answer:
1 - x - 2 + 2x = 10x - 25 - x
Step-by-step explanation:
We have the expression: 1 - (x+2) + 2x = 5(2x - 5) - x
Applying the distributive property we get:
1 - x - 2 + 2x = 10x - 25 - x
So, the following equation is the result of that step: 1 - x - 2 + 2x = 10x - 25 - x
Answer:
x = 112, y = 68, z = 112
Step-by-step explanation:
y = 68
x = z = 180 - 68 = 112
Answer:
40 minutes
Step-by-step explanation:
We have a load and a discharge, given by a speed that would be a barrel / minute.
Which means that the loading rate is: 1/20
And the discharge rate: 1/40
Since they are contrary, the result would be the subtraction between these two rates:
1/20 - 1/40 = 1 / x
1 / x = 0.025
x = 1 / 0.025
x = 40
Which means it will take 40 minutes to fill under the mentioned conditions
Since this is a right triangle, we can you the pythagorean theorem.
a^2 + b^2 = c^2
In this case,
a = 6
b = ?
c = 10
We need to substitute our values into the pythagorean theorem.
(6)^2 + b^2 = (10)^2. Reduce everything to its simplest form.
36 + b^2 = 100. Subtract 36 from both sides.
b^2 = 64. Take the square root of each side.
b = 8.
