Isaiah put a kilogram on a balance pan. how many 100 gram weights does he need too balance the scale
Answers
100g • 10 = 1000g
Isaiah would need to put 10 100 gram weights on the scale in order for it to equal 1 kilogram.
Final answer:
Isaiah would need to place 10 units of 100 gram weights on the balance scale to counterbalance the kilogram. This is because a kilogram equates to 1000 grams and each weight is 100 grams.
Explanation:
To determine how many 100 gram weights are needed to balance a scale with a kilogram on the other side, we first need to understand that a kilogram (kg) is equivalent to 1000 grams (g). This is based on the metric system, where the prefix 'kilo-' signifies a factor of 1000.
Therefore, if Isaiah has a kilogram on one side of the scale, he has a mass of 1000 grams to balance. Given that the weights he is using are each 100 grams, he would need to use 10 of these weights to balance the mass on the scale. This because 100 (grams per weight) times 10 (weights) equals 1000 grams which is equal to the kilogram placed on the other side.

Find y when x = 1/4
Answers
To remove proportionality sign, a proportionality constant is multiplied.
When x = 1/4 then y = 2.
Since, y is directly proportional to the positive square root of x.
So, , where k is proportionality constant.
Since, When x = 9, y = 12.
Thus, function become,

Answer:
y = 2
Step-by-step explanation:
from the question which says that y is directly proportional to the positive square root of x can be expressed mathematically by saying
y ∝ √x
y = k√x..................................................... where k is the constant of proportionality.
y = 12, x = 9 , k = ?
from
y = k√x
12 = k√9
12 =3k
divide both sides by the coefficient of k which is 3
12/3 = 3k/3
4 = k
therefore K = 3
now, to find the value of y when x = 1/4
from y = k√x
y = 4√1/4
y = 4 × 1/2
y = 2
therefore the value of y when x = 1/4 in this expression y = k√x is 2

And now, 85 would be a part, so that would be the numerator. The last number of 85, 5, is in the hundredth place, so the denominator would be 100.
Which would get us,
Now simplify.
5 can go into both numbers.
85/5 = 17
100/5 = 20
So you get
Your final answer is
-90 85/100 = -90 17/20

9 and 18 represent the possible number of boxes of raisins serena has.
What is expression?
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that Serena has several package of raisins. Each package contains 3 boxes of raisins. Assume she has {x} number of total boxes in the packages. Then, we can write {x} as the numbers which ar multiples of 3. So, we can write -
{x = 3} or {x = 6} or {x = 9} or ......... {x = 3n}
Therefore, 9 and 18 represent the possible number of boxes of raisins serena has.
