Answer:
44 inches
Step-by-step explanation:
The side length is the square root of the area:
A = s^2
121 in^2 = s^2
√(121 in^2) = s = 11 in
The perimeter of a square is 4 times the side length (since all four sides are the same length).
P = 4s = 4(11 in) = 44 in
The perimeter of the square is 44 inches.
The area of a square is 121 square inches, what is the perimeter of the square? inches
Answer:The perimeter = 44 inches
Explanation:Area = 121 inches²
.°. Length of a side = √(121 inches²) = 11 inches
Now,
Perimeter of the square =
Length of a side×4
= 11 inches × 4
= 44 inches.

Tyra buys 14 gallons of gas for $35. How could she figure out how much 1 gallon of gas cost
Answer:
The cost of 1 gallon is $2.5
Step-by-step explanation:
Given
Cost of 14 gallons = $35
Required
Determine the cost of 1 gallon
From the given parameters, we have:
[tex]14\ gallons = \$35[/tex]
Divide both sides by 14
[tex]\frac{14\ gallons}{14} = \frac{\$35}{14}[/tex]
[tex]1\ gallon = \frac{\$35}{14}[/tex]

Miss, Mead paid Miss, Adams $125,00 per week to start. The first week Miss, Adams' services
amounted to $162.00. How much did Miss, Meod lose on the first week's work of Miss, Adams
a, 384.00 b.$63.00 c. $28.00 d. $75.00
Answer:
Miss Meod lost $88 from Adams' first week of services.
Step-by-step explanation:
Assuming the first sentence stand
As Adams received $125 of wages the break-point is at $250 dollars
which is double of Adams' wage. Below this point the employe cannot realize a gain.
The services performed were $162 we subtract the break even point:
162 - 250 = -88
Durign the first week Miss Adams services generate a variable loss for $88

A truck driver travels at an average speed of 65 miles per hour on a 200-mile trip to pick up a load of freight. On the return trip (with the truck fully loaded), the average speed is 45 miles per hour. What is the average speed for the round trip? (Round your answer to one decimal place.)
Answer:
53.2 mph
Step-by-step explanation:
A truck driver travels at an average speed of 65 miles per hour on a 200 miles trip to collect a load of freight
On the return trip the average speed is 45 miles per hour
Average speed= total distance/total time
The first step is to calculate the total time
Time spent when going on the trip(t1) can be calculated as follows
200 = 65 × t1
t1= 200/65
t1= 3.0769 hrs
The time spent when returning from the trip can be calculated as follows
200 = 45 × t2
t2= 200/45
t2= 4.44 hrs
Total time = 3.0769 hrs + 4.44hrs
= 7.521 hrs
The total distance can be calculated as follows
= 2×200
= 400
Therefore the average speed for the round trip can be calculated as follows
= 400/7.521
= 53.2 mph
Hence the average speed for the round trip is 53.2 mph

Answer:
it's all about Order of Operations (lots of caveats here)
Step-by-step explanation:
These are exercises in the use of the Order of Operations.
The Order of Operations is a set of rules for how to evaluate an arithmetic expression. It tells you which operations to perform first, so that expressions like 1+2×3 are properly evaluated to 1+6 = 7, rather than incorrectly to 3×3 = 9, for example.
(Please be aware that some calculators do this incorrectly.)
__
In most cases involving numerical expressions, such as the ones shown, the rules are summarized by the mnemonics BEDMAS or BIDMAS or PEMDAS. The first two are more often used where British English is spoken. The meaning of these mnemonics is as follows:
B/P -- "brackets" or "parentheses". Expressions inside parentheses are evaluated first. Innermost parentheses are evaluated before enclosing parentheses. Your first expression shows an example of this:
4 ÷2 +5(10 -6)
has the expression (10 -6) evaluated first. The result is then the expression ...
4÷2 + 5×4
Note that in your last expression, the fraction bar effectively serves as parentheses for both the numerator and denominator. If this were written in plain text, it would be written as ...
(2^3 -5)/(15 +9)
__
E/I -- "exponents" or "indices". Anything with an exponent (index) is evaluated after parentheses are eliminated. Your second expression is an example of this:
(2+3)² first has the parentheses removed so you have
5²
Then the exponent is evaluated. Of course the exponent, or index, tells you how many times 5 is a factor in the product:
5·5 = 25
As with fraction bars, the typography of a typeset expression can imply grouping (parentheses). If the expression ...
[tex]2^{x+5}[/tex]
were written in plain text, it would have to be written with parentheses around the exponent:
2^(x+5)
__
D/M and M/D -- "division" and "multiplication". Here is where confusion may arise. Multiplication and division have the same priority, so are evaluated in the order they are found, left to right. The sequence of letters D or M in the mnemonic does not mean that one is performed before the other. Your first expression is an example of this:
4÷2 + 5×4 = 2 + 5×4 = 2 + 20
Here, the division happens to be first, so it is evaluated first. The multiplication is then evaluated second, because it appears to the right of the division.
__
AS -- "addition" and "subtraction". Again, confusion sometimes arises because the A appears before the S in the mnemonic. The operations of addition and subtraction have the same priority, so are evaluated in the order they are found, left to right.
_____
These are the rules. They can be modified somewhat by the properties of multiplication and addition when you actually perform the math.
For example, the expression 2×3×5 evaluated according to the rules would be = 6×5 = 30. However, we know that multiplication has associative and commutative properties, so we could evaluate this as 2×5×3 = 10×3 = 30. Similarly, we know that multiplication and division are inverse operations, so division by 2 is the same as multiplication by (1/2). Then we could evaluate ...
4÷2 = 4×0.5 = 2
This knowledge can let us rearrange an expression such as ...
5÷2×6 = 5×(1/2)×6 = 6×(1/2)×5 = 3×5 = 15
While this is a correct evaluation of the expression, you need to be careful. If your work is supposed to show an understanding of Order of Operations, you may be required to show your work as 5÷2×6 = 2.5×6 = 15.
_____
Additional comment on plain-text expressions
When in doubt, add parentheses around anything you want to consider to be a unit: numerators, denominators, exponents, fractions. Here's an example where grouping can be troublesome:
[tex]\boxed{9-3\div\dfrac{1}{3}+1} = 9-3\times3+1=9-9+1=0+1=1[/tex]
(division by 1/3 is the same as multiplication by 3/1)
When written in plain text, this is often written as ...
9 - 3 ÷ 1/3 + 1
which must be evaluated as ...
9 - 3/3 +1 = 9 -1 +1 = 9 . . . . . . the division 3÷1 is performed first
The key here is that 1/3 is intended to be treated as a fraction, so it needs to be in parentheses in plain text:
9 - 3 ÷ (1/3) + 1
This last example also shows that the order of operations treats ÷ and / and "over" and "divided by" as meaning the exact same thing: whatever is on the immediate left is divided by whatever is on the immediate right.* If that "whatever" is intended to be more than a single number or variable, it must be in parentheses.
__
* Yet another caveat: some authors consider "/" to always be a fraction bar, and ÷ to have the more conventional interpretation. Some authors consider ÷ to mean (everything to the left) divided by (everything to the right). The reason for the Order of Operations is to specify a standard interpretation of these symbols and their use.

Step-by-step explanation:
hugo received $100 for his bithday. He then saved $20 per week until he had a total of $460 to buy a printer. Use the equation to show how many weeks it took him to save the money.
Answer:
18 weeks
Step-by-step explanation:
So, Hugo received $100 for his birthday.
He saved $20 per week. Let x denote the weeks that passed. Therefore:
[tex]y=100+20x[/tex]
This equation represents the total money y Hugo has after x weeks.
The printer cost $460. Thus, set y to $460:
[tex]460=100+20x[/tex]
Solve for x.
Subtract 100 from both sides:
[tex]360=20x[/tex]
Divide both sides by 20:
[tex]x=18[/tex]
Therefore, it took Hugo 18 weeks to save up $460.

The equation is 10+3.25x+5 = 80
========================================================
Explanation:
10 = admission cost
3.25 = cost per ticket
x = number of tickets
3.25x = cost from buying x number of tickets
5 = cost of nachos & coke
10+3.25x+5 = total cost of admission, tickets, and food/drink
10+3.25x+5 = 80 since this is the amount he has in his pocket
---------------
Let's solve for x
10+3.25x+5 = 80
3.25x+15 = 80
3.25x = 80-15 .... subtract 15 from both sides
3.25x = 65
x = 65/3.25 ........ divide both sides by 3.25
x = 20
