Answer:
C) (3, -1)
Step-by-step explanation:
answer for A p e x
Answer:
in right angled triangle MNO
relationship between base and hypotenuse is given by cos angle
cosx°=b/h
cosx°=OM/MN
x°=cos-1(26/99)=74.77=74.8°
1/4 of x students made the honor roll in the first quarter
1/4 of x plus 18 equals 105
1/4 x + 18 = 105
1/4 x + 18 - 18 = 105 - 18
1/4 x = 87
Reciprocal to isolate variable
4/1(1/4 x) = 87(4/1)
x = 348
There is a total of 348 students in 7th grade
B.
A cant be, because the square root of 3 isn't a rational number/perfect square.
C can't be because the square root of 5 isn't a rational number/perfect square.
D cant be because pi isn't a rational number.
However, B can be because the square root of 25 is a rational number/perfect square. Which is 5
B. all the other questions have one and only one answer. B has several answers depending on the students surveyed
