Sharon wants to make cookies for her class bake sale. She found a recipe that calls for 2/3 cups of flour for each batch of cookies. How many batches can she make using 12 cups of flour?

Answers

Answer:

18

Step-by-step explanation:

Multiply 12 and 2 by 3 to get the "easier to work with" fraction

[tex]\frac{12}{1}[/tex] = [tex]\frac{36}{3}[/tex]

Now, multiply two until you get 36

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36

It takes 18 times to get to 36.

That means the answer is 18.

A) Because this is a convenience sample, it is likely that the sample results will be unbiased.
B) Because this is a convenience sample of college students, it is likely that bias is present and that the results will overestimate the mean number of text messages sent.
C) Because this is a convenience sample of college students, it is likely that bias is present and that the results will underestimate the mean number of text messages sent.
D) Because this is a voluntary response sample of college students, it is likely that bias is present and that the results will overestimate the mean number of text messages sent.

A triangle has a base of 16 inches and a height of 1/8 inches. What is the area?

Answers

Area of triangle = 1/2 x base x height.

Area = 1/2 x 16 x 1/8

Area = 8 x 1/8

Area = 1 square inch

The area of the triangle calculated using the area formula is 1 in²

Given the Parameters :

Base of triangle = 16 inches

Height of triangle = 1/8 inches

Area of a triangle can be obtained using the relation :

Area = 1/2 × base × height

Substituting the Parameters into the equation :

Area of triangle = 1/2 × 16 × 1/8 = 1 in²

Therefore, the area of the triangle is 1 in²
