Answer:
x = -3
Step-by-step explanation:
Step 1: Simplify signs
3x + 7 = -2
Step 2: Subtract 7 on both sides
3x = -9
Step 3: Divide both sides by 3
x = -3
An acute angle is infact 90 degrees, therefore your answer is correct.
Answer:
A
Step-by-step explanation:
He needs to collect at least 120 so if c is what he must still collect
64 +c must be greater than or equal to 120
3sqrt(2)
You can either use Pythagorean theorem or special triangle proportions to find the side that is parallel to z. Since in a 45-45-90 degree triangle, the hypotenuse is the leg times the square root of 2, and the hypotenuse is 3, we know that the leg is 3/sqrt(2) which is equal to 3 sqrt(2) / 2. Since z is twice this length, we know that z is equal to 2 x 3sqrt(2)/2 = 3sqrt(2)
By definition, an absolute frequency is the measure of how frequently an event occurs based on data from an experiment of survey.
This frequency is independent of what the other events in the experiment are and thus is termed absolute frequency.
Thus, for the given question, option B, absolute frequency is the correct option.
