Answer:
A,D,E
Step-by-step explanation:
scaled copy means the ratio of the two lengths would be same proportional constant.
The proportionality constant for Rectangle A is:
12/3 = 4
So any scaled version will have this proportionality constant same (4).
let's check:
A) 6/1.5 = 4 (OK)
B) 10/2 = 5 (NOT OK)
C) 13/4 = 3.25 (NOT OK)
D) 18/4.5 = 4 (OK)
E) 80/20 = 4 (OK)
So, correct options are A, D, and E
Answer:
Irrational number
Step-by-step explanation:
It's given,
y = (By simplifying the product of rational number 'x' and an irrational number 'y')
Where m and n are the integers and is a rational number.
(Since x = is a rational number)
Therefore, will be a rational number.
y = ⇒ Irrational number = Rational number
which is a contradictory statement.
Therefore, multiplication of rational and irrational number will be irrational.
By definition, the weight is given by
F = m * g
Where,
m = mass
g = gravity.
Clearing then the mass:
m = F / g
Substituting the values:
m = (300) / (9.81)
m = 30.58 Kg
answer:
A grocery bag can safely hold 30.58 Kg of apples before it rips apart
The answer would be 46 - This is because you would do 85/10 to find the ratio. Then you would get 8.5. You would take 8.5 then divide 391 by 8.5 getting 46.
