How many 1/8 tps can go into 1/8 cup?

Answers

Answer:

6 tps

Step-by-step explanation:

3 tsp = 1 tablespoons

16 table spoons = 1 cup

therefore 48 teaspoons = 1 cup

therefore 1/8th cup =6 teaspoons

Answer:

(1/8) cup = 6 U. S. teaspoons

Step-by-step explanation:

Do a quick Internet search.  Type '1 cup = teaspoons" into the address line as tho' you were doing a search.  Result:  1 cup = 48 U. S. teaspoons.

We want to know the teaspoon equivalent of 1/8 cup.  To get this, multiply both sides of the above equation by 1/8:

(1/8) cup = (1/8)(48 U. S. teaspoons), or  (1/8) cup = 6 U. S. teaspoons.

• At store A, 3 pounds of apples cost $12.

• At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples.

• The cost of apples at store C is shown in the graph.

(don't worry about the graph I know how to do this one)

Answer the questions to find out which store's apples are the least expensive.

2. What is the unit price of apples at store B? How did you use the equation to find the unit price? (2 points)

Answers

Answer:

The unit price is the cost per unit of an item or the cost/price for each item.

1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.

2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.

3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.

4) Store B. Because 2 is less than 3 which is less than 4.

N'(-10,-15) is the image of N after a dilation with a scale factor of 5/4, centered at the origin. What are the coordinates of N?

Answers

When the point N is dilated, the coordinate of N changes to N'

The coordinate of point N is (8,12)

How to determine the coordinate of N

The given parameters are:

N' = (10,15)

k = 5/4

To calculate the coordinate of N, we make use of:

N * k = N'

So, we have:

N * 5/4 = (10,15)

Multiply both sides by 4

N * 5 = (40,60)

Divide both sides by 5

N = (8,12)

Hence, the coordinate of point N is (8,12)
