<span>Use the formula d=sqrt[(x₂-x₁)^2+(y₂-y₁)^2] to find distance between 2 points.
DE = </span><span>√17
EF = </span><span>√18
FD = </span><span>√17
See the attachment for the complete workout.
Since,All the sides are not same to make an equilateral triangle.
So its not an equilateral triangle</span>

What is the ratio of pennies to dimes in a daller
cluponka [151]


we know that 100 pennies = 1 dollar and, 10 dimes = 1 dollar so the ratio would be;

100:10 or  100/10

and in simplest form: 100:10 = 10:1 and 100/10 = 10

What is the slope of a trend line that passes through the points (5, 80) and (7, 65)?
Vlad [161]

Answer:

-15/2 or -7.5 or -7½

Negative StartFraction 15 Over 2 EndFraction

Step-by-step explanation:

Slope or gradient of a line is the ratio of change in y co-ordinates to the change in x co-ordinates.

Therefore;

M=∆y÷∆x

The change in y co-ordinates is given by

∆y=y2-y1

Similarly, change in x co-ordinates is given by

∆x=x2-x1

Given the two points as (5, 80) and (7, 65)

X1=5 Y1=80

X2=7 Y2=65

∆y=65-80=-15

∆x=7-5=2

Hence ∆y÷∆x will be -15÷2=-7.5 or -7½

Negative StartFraction 15 Over 2 EndFraction
