The perimeter of the figure below is 152.6 ft. Find the length of the missing side.
Answer:
13.4
Step-by-step explanation:
13.4 is the answer because a perimeter is the total distance around the shape
when you take 152.6 and subtract all of the different sides your left with the length of the last side
152.6 - 13.1 - 13.1 - 9.3 - 54.2 - 9.3 - 27.1 - 13.1 = 13.4

Each week, the price of oranges at the farmer's market increases by 20%.
The price of oranges this week is $4.50.
What was the price last week?
Will give brainliest to correct answer.
The price of orange last week was $3.75
An equation is used to show the relationship between two or more numbers and variables.
The price of oranges increases by 20% each week.
The price of oranges this week is $4.50. Hence:
Price of orange last week (x) is given by:
4.5 = x + 20% of x
4.5 = x + 0.2x
1.2x = 4.5
x = 3.75
The price of orange last week was $3.75

Harold purchased a new snowmobile. The dealer gave him an option to pay the purchase price of x dollars at 100 dollars per month for y months. He would pay the remaining balance amount the following month. Which type of payment plan did the dealer offer Harold?
The dealer gave Harold
The dealer gave Harold (a deferred payment plan, an installment plan with a down payment, a rent to own plan) The expression for the amount of Harold’s last payment is (x-100y, 100y-x, x-100+y, x+100-y)
Answer:
the healer gave Harold a deferred payment plan. The expression for the amount of Harold’s last payment is x - 100y
Step-by-step explanation:
The dealer gave Harold an installment plan with a down payment. The expression for the amount of Harold’s last payment is x-100y.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
An installment plan is a type of payment plan in which the purchase price is paid in a series of payments, rather than all at once. A down payment is an initial payment made when purchasing a costly item, such as a car or house, with the intention of paying the remaining balance in a series of payments.
The expression for the amount of Harold's last payment is x - 100y. This is because the monthly payments are 100 dollars and there are y months of payments, so the total amount of payments made is 100y. The remaining balance is the original purchase price minus the total amount of payments made, which is x - 100y.

number 58 i need help with
Answer:
y = -45x + 13
Step-by-step explanation:
The equation is *** y = [tex]-5x^{2}[/tex] - 20x +13 ***
First: you have to look at [tex]-5x^{2}[/tex] which would equal -25x
Second: you have take the -25x and put into the equation... y = -25x - 20x +13
Third: You have subtract -25x - 20x which equals -45x
Lastly: Now you have y = -45x + 13 and since 13 does NOT have a variable like -45x does, you then know that you have finished the equation

In general, the larger a sample is: a. The more difficult it becomes to avoid atypical cases. b. The greater the standard deviation becomes. c. The smaller the standard deviation becomes. d. The more closely it represents the population. e. The more likely it is that it will be biased.
Answer:
d
Step-by-step explanation:
Larger samples more closely resemble the population from which they come.
Think of the difference between sampling hundreds of people from a town, perhaps asking them if they've ever ordered fast food. If you go to McDonald's and ask customers as they come out, you wouldn't expect those answers to represent the entire population of the town, right?

The ratio of yellow blocks to red blocks is 3:5, and the ratio of blue blocks to red blocks is 7:2.
What is the ratio of yellow blocks to blue blocks?
=========================================================
Explanation:
The ratio of yellow to red is 3:5. This could mean we have any of the following situations (pick one):
3 yellow, 5 red6 yellow, 10 red9 yellow, 15 redand so on. In general, we would have 3x yellow blocks and 5x red blocks. The ratio 3x:5x reduces to 3:5 when dividing both parts by x. The x is some positive whole number. The order is important because yellow must be listed first, then red second.
The same idea applies to the other ratio 7:2, which is the blue to red. In that case, we could have...
7 blue, 2 red14 blue, 4 red21 blue, 6 red28 blue, 8 red35 blue, 10 red42 blue, 12 redand so on. Notice that items in bold (in each list) have "10 red" as part of it. This is directly from the fact we multiply the 5 and 2 to get 5*2 = 10.
So we can connect the two ratios to have: 6 yellow, 10 red, 35 blue.
The ratio of yellow to blue is 6:35. This is the final answer. We cannot reduce this ratio any further due to 6 and 35 having no common factors other than 1. It's the same as saying the fraction 6/35 can't be reduced further.

Zahra runs an activity club
She needs 2 members of staff for every 15 people at the activity club.
There will be 90 people at the activity club on Monday
Zahra has 10 members of staff available for Monday.
Does Zahra have enough staff available for Monday?
(3)
Answer:
No, Zahra does not have enough staff available
Step-by-step explanation:
Given
[tex]Ratio = 2 : 15[/tex] --- staff to people
[tex]Staff = 10[/tex]
[tex]People = 90[/tex]
Required
Are there enough staff?
Start by representing the data as a ratio
[tex]Ratio = Staff : People[/tex]
So, we have:
[tex]Ratio = 10 : 90[/tex]
Divide by 10
[tex]Ratio = 1 : 9[/tex]
Multiply by 2
[tex]Ratio = 2 : 18[/tex]
This means that, she has 2 members of staff for every 18 people (instead of the expected 2 to 15 people)
Hence, Zahra does not have enough staff available
A convenience store purchased a magazine and marked it up 100% from the original cost of $2.30. A week later, the store placed the magazine on sale for 50% off. What was the discount price?
Answer:
$2.30
Step-by-step explanation:
The original price is $2.30 an it goes up by 100% which means another 2.30. So add 2.30 and 2.30 together you get 4.60 now divide that by two since the magazine is 50% off and you get the original price which was 2.30
The discount price would be an amount of $2.30.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100.
The convenience store bought a magazine for $2.30 and increased the price by 100%. A week later, the retailer reduced the price of the magazine by half.
As per the given situation, the required solution would be as:
The original price is $2.30, then it increases by 100%, or another $2.30. So add 2.30 and 2.30 to get 4.60, then split that by two because the magazine is 50% discounted to obtain the original price of 2.30.
⇒ $2.30 + $2.30
⇒ $4.60
⇒ $4.60 / 2
⇒ $2.30
Therefore, the discount price would be amount of $2.30.
