I know these numbers from a triangle because 24+30=54 and 6square root 43 is about 39
Answer:
Perpendicular
Step-by-step explanation:
L1 :
let A(-1,4) B(3,2)
the slope is : (YB - YA)/(XB -XA)
(2-4)/(3+1) = -2/(4)
the slope is
: -1/2
L2 :
let C(2,5) D(4,9)
the slope is : (YD - YC)/(XD -XC)
(9-5)/(4-2) = 4/(2)
the slope is
: 2
2×(-1/2)= -1
Perpendicular
Answer:
-2, 0, 0.4, 1.1, 2, 12, 53, 58

<h3 /><h3>What is percentage?</h3>
Percentage, which may also be referred to as percent, is a fraction of a number out of 100%. Percentage means "per 100" and denotes a piece of a total amount.
To calculate the percentage , Use the percentage formula:
![X * \frac{Percentage}{100} = Y](https://tex.z-dn.net/?f=X%20%2A%20%5Cfrac%7BPercentage%7D%7B100%7D%20%3D%20Y)
According to the question:
Sarah scored on the spelling test = ![\frac{8}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B10%7D)
Jonathan scored = 75%
By formulating both the values;
![\frac{8}{10} * \frac{75}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B10%7D%20%20%2A%20%5Cfrac%7B75%7D%7B100%7D)
= ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
Therefore ,
is the score of Jonathan.
