Answer:
C
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = E(- 2, 2) and (x₂, y₂ ) = F(4, - 6)
EF =
=
=
= = 10 → C
If an adult blinks 450 times in 30 minutes, then he will blink 900 times in 60 minutes.
A 12-year old blinks 150 times in 15 minutes, so he will blink (150 x 4) in 60 minutes, which comes out to: 600.
so 900-600
An adult blinks 300 times more in 60 minutes than a 12-year old.
Answer:
Step-by-step explanation:
Given
Bob can Paint a fence in 5 hr
so full job can be done in 5 hr
in 1 hr job is done
suppose Jen done the work in x hr
so in 1 hr part of job is done
Also if they combine they can do the job in 2 hr
so in 1 hr
so
the answer is 31.25 because 38 - 6 = 32.
32-3/4=31.25
