Step-by-step explanation:
1,280 in savings
160n
2
Hannah saves each week
50n parents put in savings each week
thus,
1,280 + 160n/2+ 50n
1,280 + 80n + 50n
1280 + 130n

Assuming that the frog starts at the bottom of the well,
how many days does it take the frog to get to the top?
I'm looking for work shown, too, please! :)
Answer: i know im a tad late here.
# 1: 56= 8 people shakes hands. There are 8 hand shakers and each handshake with 7 other people. It means one person handshakes with 7 people.
# 2: 200 divided by 4= 50 so 30 pigs is 120 legs and 40 chickens which is 80 legs
# 3. im not good at graphs. i do believe the other person made one through.
hope you have a good day, love. and sorry for my answer being late.

Sylvia is going to pick out a souvenir hat while she is on vacation. She knows the price of the hat will increase by 5% when she pays sales tax. She writes the expression h + 0.05h to find the total amount she will pay for the hat if it costs h dollars. Jin correctly writes another expression, 1.05h, that will also find the the total amount Sylvia will pay for the hat if it costs h dollars. Use the drop-down menus to explain what each part of Sylvia's and Jin's expressions mean.
Answer:
Step-by-step explanation:
Sylvia's expression
H: Price of hat
0.05: percent sales tax
0.05 h: amount of sales tax Sylvia will pay
h+0.5 h: total amount Sylvia will pay
Jin's Expression
1.05: One whole plus percent sales tax
H: price of hat
1.05 h: total amount Sylvia will pay

Find the range of ƒ(x) = –2x – 5 for the domain {–2, –1, 1, 2}.
By substituting each value of the domain of x in the function and solving it we will get the range of the function for respective domain
The given function is :
f(x) = -2x - 5
For x = -2 , f(x) is:
f(-2) = (-2*-2) - 5 = 4 - 5 = -1
For x = -1, f(x) is :
f(-1) = (-2*-1) - 5 = 2 - 5 = -3
For x = 1 , f(x) is
f(1) = (-2*1) - 5 = -2 -5 = -7
For x = 2, f(x) is
f(2) = (-2*2) - 5 = -4 -5 = -9
The range is -1 , -3 , -7 , -9
Hope this helps ..!!

Rachel earned $34 dollar sign, 34 in 4 hours at her job today. She wants to know how much she could earn (e)left parenthesis, e, right parenthesis tomorrow if she works 10 hours at the same hourly rate
Answer: Hence, She earned $85 in 10 hours at her job.
Step-by-step explanation:
Since we have given that
In 4 hours at her job, amount she earned = $34
We need to find the amount she earned in 10 hours.
We will use unitary method, to find this.
In 4 hours, amount = $34
In 1 hour, amount is given by
[tex]\dfrac{34}{4}[/tex]
In 10 hours, amount is given by
[tex]\dfrac{34}{4}\times 10\\\\=\dfrac{340}{4}\\\\=\$85[/tex]
Hence, She earned $85 in 10 hours at her job.

think of 2 numbers that subtract to 5 and multiply to 24
55.9 is what percent of 545.8? Click to select the correct answer. Round answer to the nearest whole number.
55.9 is approximately 10% of 545.8. To calculate this, divide 55.9 by 545.8 and then multiply by 100 to get the percentage, and round to the nearest whole number as per the precision of the given values.
Explanation:To find what percent 55.9 is of 545.8, we use the formula for percentage: Percentage = (Part / Whole) × 100. Plugging in the numbers, we get:
Percentage = (55.9 / 545.8) × 100
Executing the division first (as per order of operations), we have:
Percentage = 0.1024 × 100
Now, multiplying by 100 to convert to a percentage:
Percentage = 10.24%
Rounding this to the nearest whole number, we get 10%. Because the question requires following proper rounding rules based on significant figures, we consider the least precise number provided - 55.9 (tenths place) - when determining the final answer. Therefore, we round the percentage to the tenths place to coincide with the precision of the given values.

A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge S (in dollars) is given by the function =S+0.60M18.95, where M is the number of miles driven.
The company also offers an option to insure the car against damage. The insurance charge I (in dollars) is given by the function =I+0.15M3.70
.
Let C be the total charge (in dollars) for a rental that includes insurance. Write an equation relating C to M. Simplify your answer as much as possible.
You begin solving the equation 3+4x =51 by subtracting 3 from both sides.which is the best choice answer for step 2?
300 pounds of oranges were purchased at $0.24 per pound. The desired markup is 50% based on selling price, but 21% spoilage is expected. What should the selling price per pound be? (Round your answer to the nearest cent)
The selling price per pound, considering 50% markup and 21% spoilage, should be approximately $2.74, rounded to nearest cent.
To find the selling price per pound, we need to consider the cost, the desired markup, and the expected spoilage.
First, let's calculate the total cost of the oranges:
Total cost = Quantity * Cost per pound
Total cost = 300 pounds * $0.24/pound
Total cost = $72
Next, let's calculate the selling price per pound with the desired markup:
Markup based on selling price = 50%
Let's denote the selling price per pound as S.
[tex]\[S = \frac{{\text{Total cost}}}{{1 - \text{Markup}}} \times (1 + \text{Markup})\]\[S = \frac{{72}}{{1 - 0.50}} \times (1 + 0.50)\]\[S = \frac{{72}}{{0.50}} \times 1.50\]\[S = 144 \times 1.50\]\[S = 216\][/tex]
So, the selling price per pound, without considering spoilage, should be $2.16.
However, since 21% spoilage is expected, we need to adjust the selling price per pound to account for the expected loss.
[tex]\[S_{\text{adjusted}} = \frac{{S}}{{1 - \text{Spoilage}}} = \frac{{2.16}}{{1 - 0.21}} = \frac{{2.16}}{{0.79}} \approx 2.738\][/tex]
Rounding to the nearest cent, the selling price per pound, accounting for expected spoilage and desired markup, should be approximately $2.74.

1.) Kayla wants to find the distance, AB, across a river. She walks along the edge of the river 75 ft and marks point C. Then she walks 100 ft further and marks point D. She turns 90° and walks until her final location and marks point E. Point E, point A, and point C are collinear.
2.) Can Kayla conclude that ∆ABC and ∆EDC are similar? Why or why not?
3.) Suppose DE= 175 ft. What can Kayla conclude about AB? Explain. Don’t forget to label your answer.
1 - yes 100 and 75 are both collinear both are the same line.
2 - She can conclude that there both similar because the both go the same direction and both same shape.
3 - AB would equal 150 because the other one was 100 and the other angle was 25 down. So AB would equal 150.
Hope I helped
Mrs. Rodriguez has 18 packages of pens in stock at her store on monday. On tuesday, she has 5/6 the number of pens she had on monday. On Wednesday, she has 2/5 of the number of pens she had on tuesday. How many packages of pens does she hve on Wednesday?
Mrs. Rodriguez has 18 packages of pens in stock at her store on Monday.
[tex] Number \; of\; packages\; of \; Pens\; on\; Monday=18\\ \\ [/tex]
On Tuesday, she has 5/6 the number of pens she had on Monday, which means...
[tex] Number \; of\; packages\; of \; Pens\; on\; Tuesday=\frac{5}{6} \; of \ 18 = \frac{5}{6} \times 18=\frac{90}{6}=15\\ [/tex]
On Wednesday, she has 2/5 of the number of pens she had on Tuesday, which means...
\\ Number \; of\; packages\; of \; Pens\; on\; Wednesday = \frac{2}{5} \; of \ 15=\frac{2}{5} \times 15=\frac{30}{5}=6
Conclusion:
Number of packages of pens does she have on Wednesday is 6 Packages
