Ms. Posillico shoes are in ratio of 6:2:3:4; Wedges, Stilettos, Sneakers, Sandals respectfully. She owns 18 pairs of wedges. How many pairs of shoes does she own? (Show your work)
6:2:3:4
for every 6 pairs of wedges she owns 2 Stillettos, 3 sneakers and 4 sandals
18/6 =3
3*2 =6 stilettos
3*3 = 9 sneakers
3*4 =12 sandals
18 + 6 + 9 + 12 = 45 pairs of shoes
Final answer:
Given the ratio 6:2:3:4 for different types of shoes and 18 pairs of wedges, we first find the value of one unit in the ratio by dividing 18 by 6, which equals 3. Multiplying each part of the ratio by 3 gives us the total for each type, and adding those up gives us 45 pairs of shoes in total.
Explanation:
The question asks us to determine the total number of pairs of shoes Ms. Posillico owns based on the given ratio of different types of shoes and the fact that she owns 18 pairs of wedges.
Step-by-step Solution
First, we are given a ratio of 6:2:3:4 for Wedges, Stilettos, Sneakers, and Sandals respectively.
Since we know that there are 18 pairs of wedges, which corresponds to the first number in the ratio (6), we can use this information to find the value of each unit in the ratio.Divide the number of wedges (18) by the ratio number for wedges (6) to find out the value of one unit in the ratio.
Calculate the total number of pairs of shoes by multiplying the number each type of shoe per the given ratio by the value of one unit.
Add up the total pairs for each type of shoes to get the grand total.
Calculation
18 pairs of wedges / 6 = 3 pairs per unit
Then, multiply each part of the ratio by 3 to get:
Wedges: 6 * 3 = 18
Stilettos: 2 * 3 = 6
Sneakers: 3 * 3 = 9
Sandals: 4 * 3 = 12
Add up the total: 18 + 6 + 9 + 12 = 45 pairs of shoes.
Therefore, Ms. Posillico owns 45 pairs of shoes in total.

bob switches cell phone plans from Verizon to Tmobile. the monthly cost of his new plan is half the cost of his old plan, plus he added the iPhone 6s to his new plan which costs an additional $27.50 per month. If Bob's new monthly bill with Tmobile is $70 total(plan and phone), then how much is he saving per month by switching from Verizon to Tmobile? (analyze, equation, solve, check and interpret, conclusion)
Bob is saving $15 every month by switching his mobile phone plan from Verizon to Tmobile.
Explanation:This question involves understanding and solving a mathematical equation associated to a real-life context, which in this case refers to mobile phone plans and their costs. Using the provided information, we first establish that Bob's plan with Tmobile costs $70 per month, and this includes the cost of his new iPhone 6s which adds an additional $27.50 to his monthly plan.
Based on these numbers, we can uncover the cost of the plan itself (excluding the phone) by subtracting $27.50 from $70, giving us $42.50. This, according to the question, is half the cost of Bob's old Verizon plan. Therefore, to find the total cost of the Verizon plan, we double the cost of the Tmobile plan, resulting in $85 per month.
So, the monthly savings Bob makes by switching from Verizon to Tmobile is the difference between the old Verizon cost ($85) and the new T-mobile cost ($70), which amounts to $15.

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(150)?
The correct statement is: "The average number of days the house stayed on the market before being sold for $150,000." So option (a) is correct.
To find the meaning of f(150) , we need to understand that f(p) represents the average number of days a house stays on the market before being sold for price ( p ) in $1,000s.
So, f(150) represents the average number of days a house stays on the market before being sold for $150,000.
This means the correct statement is: "The average number of days the house stayed on the market before being sold for $150,000."
To calculate this, let's say there are ( n ) houses that were sold for $150,000. The total number of days these houses stayed on the market would be the sum of days for each house. Then we divide this sum by (n ) to find the average.
Let's say [tex]\( D_i \)[/tex] is the number of days house [tex]\( i \)[/tex] stayed on the market before being sold for $150,000.
[tex]\[ f(150) = \frac{D_1 + D_2 + \cdots + D_n}{n} \][/tex]
Now, let's illustrate the calculation:
Let's assume 5 houses were sold for $150,000 and their days on market were 120, 140, 160, 180, and 200.
[tex]\[ f(150) = \frac{120 + 140 + 160 + 180 + 200}{5} \][/tex]
[tex]\[ f(150) = \frac{800}{5} = 160 \][/tex]
So, [tex]\( f(150) = 160 \)[/tex] which means the average number of days a house stayed on the market before being sold for $150,000 is 160 days. Therefore, the correct statement is: "The average number of days the house stayed on the market before being sold for $150,000."
Complete Question:
Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(150)?
a. This is the average number of days the house stayed on the market before being sold for $150,000.
b. The house sold on the market for $150,000 and stayed on the market for an average of 150 days before being sold.
c. The house sold for $150,000.

Kasey has 8 packages of gelatin. She plans to fill molds that each take 1 1/3 packages of gelatin. Each mold can be divided into 6 servings. How many servings of gelatin can Kasey make?
Answer:
The number of servings of gelatin is 48
Step-by-step explanation:
step 1
Find out the number of molds
Divide the number of packages of gelatin (8) by 1 1/3 to obtain the number of molds
Remember that
[tex]1\frac{1}{3}=\frac{1*3+1}{3}=\frac{4}{3}[/tex]
so
[tex]\frac{8}{(4/3)}=\frac{24}{4}=6\ molds[/tex]
step 2
Find out the number of servings of gelatin
we know that
Each mold can be divided into 6 servings
To obtain the number of servings multiply the number of molds by 6
[tex]8(6)=48[/tex]
therefore
The number of servings of gelatin is 48
Kasey can make 36 servings of gelatin based on the number of packages she has and the amount required for each mould.
This question involves a bit of fraction work. Kasey has 8 packages of gelatin and each mold requires 1 1/3 packages of gelatin. As we need to figure out how many molds can be made, we divide the total number of packages by the amount needed for one mold. This equals 8 ÷ 1 1/3, which equals to 6 molds when converted into an improper fraction.
Subsequently, we understand that each mold can be divided into 6 servings. Therefore, Kasey could make a total of 6 molds x 6 servings which equals 36 servings of gelatin.

the 7 in the thousands place is 10 times greater than the 7 in the hundreds place?
the 7 in the thousands place is 100 times greater than the 7 in the hundreds place?
the 7 in the thousands place is 7 times greater than the 7 in the hundreds place?
The 7 in the thousands place is ten times greater than the 7 in the hundreds place, adhering to the base-10 structure of our numbering system; other proposed multipliers are incorrect.
Explanation:The question explores the concept of place value in our decimal numbering system, which is based on powers of ten. Specifically, it examines the comparative value of digits in the thousands and hundreds places. Using the decimal system, each place value to the left is ten times greater than the one immediately to its right.
The second statement suggesting that the 7 in the thousands place is 100 times greater is incorrect; it overlooks the base-10 structure of our numbering system. Finally, the suggestion that the 7 in the thousands place is 7 times greater is also incorrect, as it misinterprets the multiplicative property of the decimal system. Therefore, the 7 in the thousands place being 10 times, 100 times, or 7 times greater than the 7 in the hundreds place aligns with the concept of powers of 10.
