You are buying balloons for a party. A small balloon costs $2. A large balloon costs $3. Write an algebraic expression for the cost of x small balloons and y large balloons. Then find the total cost for 11 small balloons and 5 large balloons.
Answers
cost for total of small ballons=x times 2 or 2x
cost of total of big ballons=y times 3 or 3y
total is costsmall+costbig=2x+3y
so
TC=2x+3y
if you have 11 small and 5 big (x=11 and y=5), what is TC?
input
TC=2(11)+3(5)
TC=22+15
TC=37
total cost is $37

by powers of 10.

The pattern of zeros in the product when multiplying by powers of 10 is a result of our base-10 decimal system. Each place value in a decimal number represents a power of 10.
When you multiply a number by a power of 10, you are essentially shifting its digits to the left by the number of places equal to the exponent of 10.
Let's illustrate this with an example. Suppose we have the number 456, and we want to multiply it by powers of 10:
1. 456 multiplied by 10:
- When we multiply 456 by 10, we are essentially shifting all the digits one place to the left. So, we get 4560. Here, we've added one zero.
2. 456 multiplied by 100:
- When we multiply 456 by 100, we are shifting all the digits two places to the left. So, we get 45600. In this case, we've added two zeros.
3. 456 multiplied by 1,000:
- When we multiply 456 by 1,000, we are shifting all the digits three places to the left. So, we get 456000. Here, we've added three zeros.
And so on...
In general, when you multiply a number by 10 raised to the power of "n," you will add "n" zeros to the end of that number. This is a fundamental concept in our decimal number system and is why the pattern of zeros emerges when multiplying by powers of 10. Each power of 10 represents a place value shift, and adding zeros simply extends the number in the same manner.

One foot is approximately 33.33 percent of a yard.
Given data:
To find the percentage of one foot in relation to a yard, we need to compare the length of one foot to the length of a yard and express it as a percentage.
One yard is equivalent to 3 feet, so we can set up the following proportion:
1 foot : 3 feet = x percent : 100 percent
Cross-multiplying, we get:
1 foot * 100 percent = 3 feet * x percent
100 percent = 3x percent
Dividing both sides by 3, we find:
x percent = 100 percent / 3
x percent = 33.33 percent (rounded to two decimal places)
Hence, one foot is approximately 33.33% of a yard.
