Answer:

-1 , 1 , 3 , 5 , 7

Step-by-step explanation:

An = = 2n - 3

n = 1; A1 = 2*1 - 3 = 2 - 3 = -1

n =2; A2 = 2*2 - 3 = 4 - 3 = 1

n = 3; A3 = 2*3 - 3 = 6 - 3 = 3

n= 4; A4 = 2*4 - 3 = 8 - 3 = 5

n = 5; A5 = 2*5 - 3 = 10 - 3 = 7

Three sizes of popcorn buckets are on sale at a movie theatre. The large bucket holds 15 1/2 cups of popcorn. The medium bucket

leonid [27]

Answer:

The medium bucket can hold 5 and 1/6 cups of popcorn.

Step-by-step explanation:

Remember that for mixed numbers, like "4 and 1/5", the way of writing that number is (4 + 1/5).

Now, let's solve the question:

We know that the large bucket holds (15 + 1/2) cups.

We also know that the medium bucket holds 1/3 of the large bucket, and we want to know how many cups does the medium bucket hold.

This is just (1/3) times the amount that the large bucket holds, so we have:

(1/3)*(15 + 1/2) cups

Using the product distributivity, we can write:

(1/3)*(15 + 1/2) cups = ( (1/3)*15 + (1/3)*(1/2) ) cups = (5 + 1/6) cups

Then we can conclude that the medium bucket can hold 5 and 1/6 cups of popcorn.

A rocking horse has a weight limit of 60pounds. What percentage of the weight limit is 33 pounds? What percentage of the weight

bixtya [17]

Answer:

The percentage is 55% when weight limit is 33 pounds.

The percentage is 190% when weight limit is 114 pounds.

The 95% of the limit weighs 57 pounds.

Step-by-step explanation:

Given:

Weight limit of rocking horse = 60 pounds.

We need to find:

a) What percentage of the weight limit is 33 pounds.

b)What percentage of the weight limit is 114 pounds.

c) What weight is 95% of the limit.

Now Solving for a we get;

Weight limit = 33 pounds

Now percentage of the weight limit can be calculated by dividing given weight limit with total weight limit and then multiplying by 100 we get;

framing in equation form we get;

percentage of the weight limit = $\frac{33}{60}\times100 = 55\%$

Hence The percentage is 55% when weight limit is 33 pounds.

Now Solving for b we get;

Weight limit = 114 pounds

Now percentage of the weight limit can be calculated by dividing given weight limit with total weight limit and then multiplying by 100 we get;

framing in equation form we get;

percentage of the weight limit = $\frac{114}{60}\times100 = 190\%$

Hence The percentage is 190% when weight limit is 114 pounds.

Now Solving for c we get;

Percentage Weight = 95%

Now Amount of weight limit can be calculated by multiplying Percentage weight limit with total weight limit and then Dividing by 100 we get;

framing in equation form we get;

percentage of the weight limit = $\frac{95}{100}\times60 = 57 \pounds$

Hence The 95% of the limit weighs 57 pounds.
