Answer:
Step-by-step explanation:
The ratio of corresponding sides DN and KI is 12 : 4 = 3 : 1. The same ratio applies to altitudes DQ and KO. Since the difference between these altitudes is 6 and the difference between their ratio units is 3-1 = 2, each ratio unit must stand for 6/2 = 3 units of linear measure. That is, ...
DQ = (3 units)·3 = 9 units
KO = (3 units)·1 = 3 units
Then the base lengths QN and OI can be found from the Pythagorean theorem:
KI² = KO² +OI²
4² = 3² +OI²
OI = √(16 -9)
OI = √7
QN = 3·OI = 3√7
The details of the packages are not posted, however I can tell you how to find the answer.
First determine how many pencils are in each pack.
Then divide the price of the pack by the number of pencils to find out which pack has the least cost per pencil. To put this in equation form:
Whichever pack has the least cost per pencil is the one that is the best priced.
if point A is located at (0,-8) and B is located at (4,-5)
We use distance formula
(0,-8) is (x1, y1) and (4,-5) is (x2,y2)
x1 = 0 , y1= -8 , x2= 4 and y2= -5
so d= 5
The distance between 2 points is 5
Answer:
the y intercept is three and the gradient is also three
y=3x + 3
