Which argument is valid?

1 answer:

8 0

1 - True. If a number is divisible by 12 it's divisible by 6 and thus by 3

2 - False. A rhombus needn't have square angles

3 - False. the second proposition is unrelated to the first one, and doesn't allow us to deduce that cats have fur.

4 - False - We cannot link the first and second proposition in any way to make the third

10 POINTS + BRAINLIEST TO FIRST CORRECT ANSWER!!! THANK YOU!

Fofino [41]

Answer:

The answer is A (Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate)

Step-by-step explanation:

Because the proportional relation is defined by k = $\frac{y}{x}$ . If ratio is $\frac{units}{1unit}$ then it is a rate. Unit rate means per 1 unit such as $\frac{amountofmoney}{1kg}$ or $\frac{km}{1hour}$ thus the correct answer is A.

Blababa [14]

So, say your # was 6,234,578. you would go to the seven and look to the number next to in, so 8, and if the neighbor is 5 or bigger, you make the number, in this case a 7 an 8. Last, you make all the other #s after the one you rounded 0. So the answer would be:

An office equipment store buys highlighter pens boxes at a wholesale price of $15 each. It then marks up the price by 94%, and s

Stells [14]

Answer:

Option (d) is correct.

Step-by-step explanation:

Given that,

The wholesale price of a pen is $15.

It then marks up the price by 94%.

Its marked price is equal to 94% of $15. So,

$\text{MP}=\dfrac{94}{100}\times \$15\\\\\text{MP}=\$14.1$

Selling price of the highlighter pen is equal to the sum of marked price and the wholesale price.

SP = $14.1+$15

SP = $29.1

Hence, the marked price is $14.1 and the selling price is $29.1
