Answer: 0.4

Step-by-step explanation: In order to write 2/5 as a decimal, we need to find a fraction equivalent to 2/5 with a 10 in the denominator.

Notice that if we multiply both the numerator and denominator by 2, we get the equivalent fraction 4/10 which we can now write as a decimal.

Since 4/10 is equivalent to the decimal 0.4, this means that 2/5 must be equivalent to the decimal 0.4.

Find the slop from the given equation. 2x + 4y + 7 = 0
antiseptic1488 [7]

The slope of the line would be -1/2.

To find the slope we need to make the line in the form y = mx + b:

2x + 4y + 7 = 0

2x + 4y = -7

4y = -2x - 7

÷ 4

y = (-2/4)x - (7/4)

-2/4 simplifies to -1/2.

I hope this helps!

Omar has 2 3/4 cups of dough to make dumplings. If he use 3/16 cup of dough for each dumpling, how many whole dumplings can Omar
andrey2020 [161]

Answer:

14

Step-by-step explanation:

Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.

a stack of cards is placed next to a ruler, and the height of stack measured to be 3/4inches. how thick is one card
4vir4ik [10]

Total thickness of the stack of cards = 3/4 inch or 0.75 inch

In a full stack of cards, there are 52 cards.

Hence, the thickness of 52 cards = 0.75 inch.

To find the thickness of one card, we divide the total thickness with the total number of cards.

Thickness of one card = \frac{0.75}{52} = 0.014423 inch

1 inch = 2.54 cm

0.014423 inch is approximately equal to 0.34 cm.

Answer = 0.34 cm
