Answer:
7
Step-by-step explanation:
X is 120 degrees, you ask to find the value of y, but there is no y
<span>If you have an equilateral triangle, the median is also the altitude so - That means that if you draw altitude, it will bisect the base of the triangle and meet at two right angles. That gives you two of the measurements for the right triangle - the side (6) hypotenuse, and the base (3). You can then figure out the height using the Pythagorean as you have the a and the c for the theorem. Then you can use 1/2 base times height to find the area.

Answer:
0.79 = 79% probability that a seed selected at random from the mixed will germinate.
Step-by-step explanation:
Probability of a seed germinating:
85% of 40%(from company A)
75% of 60%(from company B)
Then
0.79 = 79% probability that a seed selected at random from the mixed will germinate.
Answer:
x = 1
Step-by-step explanation:
4(2x + 1) - 3 = - 3(x - 4) ← distribute parenthesis on both sides
8x + 4 - 3 = - 3x + 12
8x + 1 = - 3x + 12 ( add 3x to both sides )
11x + 1 = 12 ( subtract 1 from both sides )
11x = 11 ( divide both sides by 11 )
x = 1
