Answer:
HK = 20
Step-by-step explanation:
LM = (1/2) HK {Mid point theorem}
2*(10x - 90) = 10x - 80
2*10x - 2*90 = 10x - 80
20x - 180 = 10x - 80 {add 180 to both sides}
20x = 10x - 80 + 180
20x = 10x +100 {Subtract 10x from both sides from }
20x -10x = 100
10x = 100
x = 100/10
x = 10
HK = 10x - 80
= 10*10 - 80
= 100 - 80
= 20
Answer:
required time is here 45 minutes
Step-by-step explanation:
given data
apples = 100
bananas = 100
oranges = 100
pears = 100
solution
we have here 4 different kind of fruit
so that it is possible for each kind of fruit is
each kind of fruit is = 4 × 11 = 44
so each kind contain 11 fruit
as that 45th fruit make a dozen
now 1 fruit is pick every minute
'so we take here 45 minute to pick up 45 fruit
so that required time is here 45 minutes
Answer:
The sample is the amount of people because not everyone is getting chosen
Step-by-step explanation:
Answer:
y = - x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 2) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line
m = 
= 
= - 1 , thus
y = - x ← equation of line
