Answer:
Area = 45 km
Step-by-step explanation:
The area of a parallelogram = base * height
It is given that:
Base = 6 km
Height = 9 km
When these values are substituted into the are equation, the result is:
Area = 6 * 9
Area = 45 km
Hope this helps :)
Okay, here we have this:
Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:
Solving for x:
Finally we obtain that 87.5mL of water should be used for 250g of plaster.
Let <span>sin(90° - )------------------------ > sin (90-x)
</span>sin(a - b<span>) = sin a*cos b - cos a*sin b
</span><span>so
</span>sin(90 - x) = sin 90*cos x - cos 90 * sin x
sin(90 - x) = 1*cos x - 0* sin x-------- > cos x
the answer is the option <span>D. cos()</span><span>

Answer: Hi!
So if in the box there are 2 balls and she chose one at random, then she had a 0.5 probability of chose each ball, and then she has a 0.5 probability of choosing the ball that is associated to the correct answer, then she has a 0.5 of getting each answer correct.
Now she has 4 questions, then the probability for getting all of them correct is the product of the probabilities for each one; this is:
0.5*0.5*0.5*0.5 = 0.0625
multiplied by 100%, we get a 6.25% of getting the four answers correct using this method.
Composite numbers are numbers that have the same set of factors
