B. y=4/5x its just taking half
1700, just use the inverse operation. The problem would look like this ( not inverse operation ) x ÷ 33 1/3 = 51
All you have to do is multiply the two numbers.
51 x 33 1/3 = 1700
Now plug it back in and check
1700 ÷ 33 1/3 does indeed equal 51.
Answer: Eleventh Grade
Step-by-step
The ratio of tenth graders to the school's total population is 86:255 = 33.7%.
The ratio of eleventh graders to the school's total population is 18:51 = 35.3%.
Since the probability of a student being in either tenth, eleventh, or twelfth grade = 1 = 100% (that is, certainty), then the probability of a randomly drawn student being in twelfth grade is (100-33.7-35.3)% = 31.0%.
When randomly choosing one student from the whole school, it is most likely (35.3%) that the student is in the eleventh grade.
Answer:
= 8.33 inches
Step-by-step Explanation
First add 49 + 16, which equals 65, and subtract that result from 180, since a triangle equals 180 degrees and you find out angle C is equal to 115 degrees.
Now using the formula sinA/a = sinB/b = sinC/c, plug in values and you'd get the equation sin49 x 10/sin115. After solving the equation you'd get about 8.32729886047258 inches.
= 8.33
