1:
x+19≤-5
x≤-5-19 (by transposition)
x≤-24
2:
3z>-36
z>-36/3 (divide both sides by 3)
z>-12
3:
-0.3n≤5.4
n≥5.4/(-0.3) (divide both sides by -0.3, AND switch direction of inequality)
n≥-18
Answer:
6 is 25% of 24.
Step-by-step explanation:
6 ÷ 24 = 0.25 = 25%
What are the medians for the height and weight distribution, respectively?
A. 170, 179
B. 183, 167
C. 167, 183
D. 179, 170
E. 165, 175
Arranged Height distribution (cm): 154, 158, 159, 163, 165, 167, 167, 174, 177, 178, 181, 186, 191
Arranged Weight distribution (lbs): 157, 163, 168, 173, 173, 177, 183, 184, 187, 189, 190, 192, 193
The median is the middle number. [there are 13 numbers each. hence the respective median are the 7th numbers]
Median Height = 167
Median Weight = 183
Answer:
The time it will take is 13 hours
Step-by-step explanation:
From the given statement, we can generate the following inverse proportion relationship between t and s
t ∝ 1/s
The time it will take is 13 hours
Remark
I think we are to assume that the line is a straight one and that it contains a total of 180o at the intersection.
Equation
2x + 7 + 6x - 9 = 180o
Solve
Combine the like terms on the left.
2x + 6x + 7 - 9 = 180
8x - 2 = 180o Add 2 to both sides.
8x - 2 + 2 = 180 + 2
8x = 182 Divide by 10
8x/8 = 182/8
x = 22.75
But that is not the answer.
You need to find 6x - 9
Angle = 6x - 9
Angle = 6*18.2 - 9
Angle = 127.5 <<<<< Answer.
