Step-by-step explanation: do the abc's its easy you should try.
Answer:
2
Step-by-step explanation:
(1/64)^-(1/6) = 64^(1/6) = 2
1 kg is equal to a little over twice the lbs. So if you have 75 kg it'll be over 150 lbs. Therefore 75 kg weighs more.
65:x = 13:15
Divide 65 by 13.
65/13=5
Multiply 15 by 5 for the proportionate factor.
75.
There are 75 girls in the classroom.
We're looking for the total so we need to add 65 with 75.
65+75= 140.
There are 140 total students.
The slopes of perpendicular lines are opposite reciprocals
The true statement is that segments FG and HJ are perpendicular
<h3>How to determine the relationship between the segments</h3>
The coordinates of the points are given as:
F = (3,1)
G = (5,2)
H = (2,4)
J = (1,6)
Start by calculating the slopes of FG and HJ using the following slope formula
![m = \frac{y_2 -y_1}{x_2 -x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-x_1%7D)
So, we have:
![FG = \frac{2 -1}{5 -3}](https://tex.z-dn.net/?f=FG%20%3D%20%5Cfrac%7B2%20-1%7D%7B5%20-3%7D)
![FG = \frac{1}{2}](https://tex.z-dn.net/?f=FG%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
Also, we have:
![HJ = \frac{6 - 4}{1 - 2}](https://tex.z-dn.net/?f=HJ%20%3D%20%5Cfrac%7B6%20-%204%7D%7B1%20-%202%7D)
![HJ = \frac{2}{-1}](https://tex.z-dn.net/?f=HJ%20%3D%20%5Cfrac%7B2%7D%7B-1%7D)
![HJ = -2](https://tex.z-dn.net/?f=HJ%20%3D%20-2)
To determine the relationship, we make use of the following highlights
- Parallel lines have the same slope
- The slopes of perpendicular lines are opposite reciprocals
From the computation above, we have:
- The slopes of both lines are not equal
- The slopes are opposite reciprocals i.e. 2 = -1(-1/2)
Hence, segment FG and HJ are perpendicular
