Korvikt [17]

Answer:

First we must learn to dissect a question.

<h3>Explanation:</h3>

Part 1

We can list our facts first:

  • Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
  • She needs 13 dozen cookies

She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons

6.5 \times 1.5 = 9.75 \: teaspoons

<h3>Part 2</h3>

She needs 9.75 teaspoons and 3 teaspoons make a tablespoon

Sveta_85 [38]

Answer:

The per hour rate is 0.5 inches per hour

Step-by-step explanation:

Here, we want to calculate the rate at which the level of the water increased

Mathematically, we can get this by dividing the amount of increment by the time it took

That would be 3 inches divided by 6 hours

= 3/6 = 0.5 inches per hour

Forty is no greater than the difference of a number and 2
GuDViN [60]
This can be written as:
40  \leq  n - 2

"No greater than" does not necessarily mean less than, but it just means it cannot go over. So equal to or less than.

"The difference of a number and 2" can be represented as "n - 2"

If you were to solve this inequality, you would end up getting:
42  \leq  n or n  \geq  42

Hope this helps! :)

almond37 [142]
If there are 36 potato plants, and they are in 4 even rows, that means that there is 9 in each column because 9 x 4 is 36. Since 7 of them were eaten by the sheep and the goat, that means that there are 2 leftover in that row that the sheep and goat got to since 9-7 is 2.

Jake has two pet guinea pigs named fluffy and scruffy. Fluffy is8 1/8 inches long. Scruffy is 10 1/4 inches long. How much longe
miss Akunina [59]

Answer:

Scruffy is 2\frac{1}{8} inches longer than Fluffy.

Step-by-step explanation:

Length of Scruffy = 10\frac{1}{4} inches

Length of Fluffy = 8\frac{1}{8} inches

We have to calculate how much Scruffy is longer than Fluffy.

Difference of their lengths = 10\frac{1}{4}-8\frac{1}{8}

                                            = (10 - 8) + (\frac{1}{4}-\frac{1}{8})

                                            = 2 + (\frac{2-1}{8})

                                            = 2 + \frac{1}{8}

                                            = 2\frac{1}{8} inches

Therefore, Scruffy is 2\frac{1}{8} inches longer than Fluffy.
