Answer:
1. 34 students.
2. 6 is the median height.
3. 10 have 171cm 4 have 190cm.
4. 2 students have no taller than 171cm.
Step-by-step explanation:
I really can't explain it because it hard to explain how i answered your question.
PN = LO
__________________________
(LO)^2 = (LN)^2 + (NO)^2
(LO)^2 = 6^2 + 8^2
(LO)^2 = 36 + 84
(LO)^2 = 100
LO = √100
LO = 10
__________________________
Thus :
PN = 10
Answer:
Angle 1: 60
Angle 2: 120
Step-by-step explanation:
Because of corresponding angles, the measure of the angle next to Angle 1 is 50 degrees, due to corresponding angles. Because of the sum of angles in a triangle is 180 degrees, measure of Angle 1 is 60 degrees. The linear pair of angle 2 is angle 1, which is 60 degrees. Because of linear pair, measure of angle 2 is 120 degrees.
Answer:
4(-7)
4*-7=-28
Whenever multiplying +positive sign and -negative sign= -negative sign
PEMDAS
When solving an equation we do them in reverse order
AS adding and subtracting
MD multiplication and division
E exponents
Basically we are trying to get the variable alone.
12=10-3x
subtract 10 from each side
then divide by -3 on each side
3/5 x -12 = 18
first add 12 to each side
then multiply by 5/3 to each side
