Answer: RA, EJ, JT
Explanation:
When dealing with 3 dimensional figures, you must handle three concepts to analyze the spatial relationship of the lines. Those are:
- Perpendicular lines: it refers to lines that intersect each other at a 90° angle (right angle). This only can happen if the lines.
- Skew lines: it refers to lines that are not parallel but are in different planes and cannot not intersect each other.
- Parallel lines: are lines that are in the same plane but cannot intersect each other.
The given figure is a perfect model to understand what each one of those concepts mean.
Starting by the segment JA, you find that:
- The segments EH, QP, and TR are parallel to segment JA, because you can find a plane formed by JA and any of those segments, and yet JA will never intersect any of them.
- Segment JA is skewed respect segments QT, PR, QE, and PH, because they are in different planes.
- Segment JA is perpendicular to EJ, HA, JT and RA, because JAintersects any of them on a right angle.
Hence, the right choices are segments RA, EJ and JT
Answer:
-16
Step-by-step explanation:
The average of –25, –70, 15, –31, –25, and 40 is -16
To determine the average of the numbers given, we shall find their sum then divide this sum by the number of values;
The sum of the numbers is;
-25-70+15-31-25+40 = -96
We have a total of 6 values, thus the average becomes;
(-96)/6 = -16
I think its D
so there is 530 boys and 180 bicycles
only 30 girls had bicycles
so 530 + 30= 560/1000
not sure
If Tatiana already has 5 bracelets and can only buy packs of 4 bracelets, if she buys p packs she will have
bracelets. In fact, the 5 represents the bracelets she already has, and then we add 4p bracelets, because she bought p packs with 4 bracelets each.
We need this number to be at least 32, so we want
To solve the inequality, we can subtract 5 from both sides:
And divide both sides by 4:
Since p has to be an integer, we pick the first integer to be greater than 27/4, which is 7.
Answer:
The choose a. f(x) = x+5
Step-by-step explanation:
f(-1)= -1+5=4
f(0)=0+5=5
