If Skylar bought 23 chicken wings for $32.20 then the cost of 13 wings would be using the concept of estimation.
As per the question statement, Skylar bought 23 chicken wings for $32.20. We are supposed to calculate the cost of 13 wings. We will use the concept of estimation.
Cost of 23 wings = $32.20
Cost of 1 wing = $32.20/23 = $1.40
Therefore cost of 13 wings = $1.40 * 13 = $18.20
So, if Skylar bought 23 chicken wings for $32.20 then the cost of 13 wings would be using the concept of estimation.

8 × [tex]10^5[/tex] is 200 times greater than 4 × [tex]10^3[/tex] as according to multiplying and dividing as per the scientific notation of multiplication and division.
What is scientific notation?A kind of representation of number which is some power of 1/10 can also be expressed in as easily in scientific notation.
1/10 = [tex]10^{-1[/tex] (“ten to the minus one power”)
More generally, the expression “[tex]10^{-n[/tex]” (where n is a whole number) means (1/10) n. Thus
[tex]10^{-3[/tex] = [tex]\frac{1}{10}^{-3}[/tex]
= 1/1000
[tex]10^{-8[/tex] = [tex]\frac{1}{10}^{-8[/tex]
= 1/100,000,000
Scientific notation was invented to help scientists (and science students) deal with very large and very small numbers, without getting lost in all the zeros.
Herein this question
8 × [tex]10^5[/tex] can also thus be written as 2 x 4 × [tex]10^5[/tex]. On dividing with 4 × [tex]10^3[/tex] we get 2 x [tex]10^2[/tex]. Thus, it is 2 x [tex]10^2[/tex] i.e., 200 times larger than 4× [tex]10^3[/tex].
The expression “10n”, where n can be stated as a whole number, simply means that “10 is raised to the nth power,” or in other words, a number that is got by using 10 as a factor n times.
You can also notice that the number of zeros that are present in the ordinary decimal expression is absolutely equal to the power to which thus 10 is raised.
If any kind of number is expressed in words, first we have to write it down as an ordinary decimal number and then we have to convert it. Thus, the value “ten million” becomes 10,000,000. There are a total of seven zeros, so in powers of ten notation ten million is written [tex]10^7[/tex].

What is an linear equation in one variable?Linear equation is an equation containing one unknown variable with power one and constants.
The standard form of an linear equation in one variable x is :
ax + b = 0 , where a, b are constants
x= -b/ a is solution if this equation or we can solve this equation by adding or subtracting, multiplying, dividing same number to both sides.
Given that there are two types of candies one is of x dollars per pound
and one is of $1.50 per pound
Cost of 2lb of candy that costs x dollars per pound = 2 × x = $ 2x
Cost of 3lb of candy that costs $1.50 per pound = 3 × 1.5 = $ 4.5
2lb of one type of candy and 3lb of other type of candy are mixed to form a mix of weight 2lb + 3lb = 5lb
The cost of one pound of mixture = $2.50
The cost of 5lb of such mixture = $ 5× 2.50 = $ 12.5
Cost of 5lb mix = Cost of 2lb candy of first type + Cost of 3lb candy of second type
⇒ 12.5 = 2x + 4.5
Subtract 4.5 from both sides,
⇒ 12.5 - 4.5 = 2x
⇒ 8 = 2x
Divide both sides by 2
⇒ 4 = x
Therefore, the cost of first type of candy is $ 4 per pound

4) A group entering a zoo purchased 33 admission tickets for a total of $139.50. Adult tickets (x) cost $7.50 and
tickets for children (y) cost $3.50. How many of each type of ticket were purchased?
/5 points
The number or children tickets are 24 and adults tickets are 9.
How to illustrate the information?Adult tickets (x) cost $7.50 and tickets for children (y) cost $3.50. The equation will be:
7.5x + 3.5y = 139.5
There are 33 tickets. This will be:
x + y = 33
x = 33 - y.
Recall 7.5x + 3.5y = 139.5
Substitute for x.
7.5(33 - y) + 3.5y = 139.5
247.5 - 7.5y + 3.5y = 139.5
-4.5y = 139.5 - 247.5
4.5y = 108
y = 108/4.5
y = 24
Number of children ticket = 24
Adult tickets = 33 - 24 = 9

The boca grande causeway in florida is about 1 4/9 times as long as the golden gate bridge in san francisco golden gate bridge is about 9000 feet long about how long is the boca grande causeway
The length of the Boca Grande Causeway = 13,000 feet.
When do we use multiplication ?Repeated addition of the same number is made easier by multiplying the numbers. When we need to merge groups of similar sizes, we employ it. For instance, if there are 5 baskets, each containing 4 apples, we can use multiplication to get the total number of apples, which is 5 x 4 = 20 apples.
We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.
Given: The boca grande causeway in florida = 1 4/9 times golden gate bridge
Length of the Golden Gate Bridge = 9000 feet
Thus the length of the Boca grande causeway = 1 4/9 × 9000
= 13/9 × 9000
On further solving we get
= 13 × 1000
= 13,000 feet .

The price of one canadian dollar in US dollars is 91 cents or 0.91 US dollars.
It is given that the price of a US dollar is 1.10 Canadian dollars in the market.
Thus we can say that,
1.10 Canadian Dollar = 1 US Dollar
∴ 1 Canadian Dollar = [tex]\frac{1}{1.10}[/tex] US Dollars
