Answer:
If the strip is 12cm and it is asking for 25% of it, you can divide 12 by 4, as 25 is 1/4 of 100.
The answer will be 3cm
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equations
solving the system of the equations
Arrange the equation variables for elimination
solve
Divide both sides by -3
Therefore, the solutions to the system of the equations are:
But, it seems none of the options is true.
Hello,
When you have an inscribed quadrilateral, the opposite sides are supplementary.
So you can write and solve the following equation.
x + 6x + 19 = 180
7x + 19 = 180
7x = 161
x = 23
Now, plug in 23 for X and we will find the measurement of B.
6(23) + 19
138 + 19
157
The measure of angle B is 157 degrees. (The picture is not drawn to scale)
Good luck,

I think that its d seems like it might hope this is right
Answer: C.) 4/27
Step-by-step explanation:
Given that:
One out of three cards is a winner :
P(winning) = 1 / 3
Therefore, P(not winning) = P(losing) :
1 - P(winning) = 1 - 1/3 = 2/3
Probability that shenice will first win on her third try can be interpreted as:
1st try = lose, 2nd try: lose, 3rd try : win
P(losing) × p(losing) × p(winning)
(2/3) × (2/3) × (1/3)
4 / 27
Probability of first winning on third try = 4/27
