Which situation represents a multiplicative relationship? A) Kevin is 8 years older than his brother Sean. B) For every cat at t
Lunna [17]

Answer:

Option B represents a multiplicative relationship.

Step-by-step explanation:

We are required to find the situation that represents a 'multiplicative relationship'.

According to the options, we have,

A) Kevin is 8 years older than his brother Sean.

This gives us the relation that, Kevin's Age = 8 + Sean's Age.

Thus, this is not a multiplicative relationship.

B) For every cat at the pet store, there are 2 dogs.

We get that, for 1 cat, there are two dogs.

So, Number of dogs = 2 × Number of cats.

Thus, this is a multiplicative relationship.

C) A buy one get one free sale on sweaters at the clothing store.

So, during the sale a person can buy 1 + 1 i.e. 2 sweaters.

Thus, this is not a multiplicative relationship.

D) James always keeps $100 more in his savings than his checking account.

This gives us the relation that, Savings balance = 100 + Checking balance

So, this is not a multiplicative relationship.

Hence, option B represents a multiplicative relationship.

Frank reasoned that in the number 0.555, the value of the 5 in the thousands place is ten times as great as the 5 in the hundred
Gnom [1K]

The given number is 0.555 which can be written as

0+ \frac{1}{10}*5 + \frac{1}{100}* 5+ \frac{1}{1000} * 5

As we see that after decimal, every next digit is 1/10 times of the current digit .

Therefore the statement , " the value of the 5 in the thousands place is ten times as great as the 5 in the hundredth place " is not correct .

eimsori [14]

Answer:

$18.90

Step-by-step explanation:

The way to do percentages is actually pretty easy.

since it's taking 30% of you are left with 70%. Take 70 and divide it by 100. This gives you .70

Now what you do is you take the price of the time and multiply it by the .70

So 27.00 * .7 = 18.90

So Noah paid 18.90
