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.

Step-by-step explanation:
each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 ft if there are four blades on the windmill what is the total area of the blades
The total area of the blades is the area of a triangle multiplied by 4.
We have then:
[tex] A = (4) * (1/2) * (b) * (h)
[/tex]
Where,
b: base of the blades
h: height of the blades
Substituting values we have:
[tex] A = (4) * (1/2) * (7) * (4)
[/tex]
Doing the calculation we have that the area of the blades is given by:
[tex] A = 56 feet ^ 2
[/tex]
Answer:
The total area of the blades is:
[tex] A = 56 feet ^ 2 [/tex]
Each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 ft if there are four blades on the windmill what is the total area of the blades
Total area of blades= Sum of areas of all blades
=Sum of areas of four blades
As, all blades have same dimension
SO, Total area of blades=4*Area of one blade
As, shape of blade is triangle, Area of triangle=[tex] \frac{1}{2} [/tex]*base*height
Total Area of blades =4* [tex] \frac{1}{2} [/tex] * base * height
Total Area of blades =4* [tex] \frac{1}{2} [/tex] * 7 * 4
Total Area of blades =4* [tex] \frac{1}{2} [/tex] * 28
Total Area of blades =4* 14
Total Area of blades =56 square feet

Why might algebra tiles not be a good tool to use to factor x^2 + 18x + 80? Explain.
Sample Response: Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

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

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.

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

Quiz: Area of Rectangles Assessment items A rectangle is 13 yards long and 23 yards wide. What is the area of the rectangle? Enter your answer in the box as a fraction in simplest form. $$ yd2 Assessment navigation
Length of rectangle=13yards
Width of rectangle=23yards
The formula for, Area of rectangle= length*width
So, Area=13*23[tex] yards^{2} [/tex]
As, 13 multiplied by 23 is 299
So, Area=299[tex] yards^{2} [/tex]
To represent in fractions, Area=[tex] \frac{299}{1}yards^{2} [/tex]

1.) There are 8 people in a room.
Each person shakes hands with each of the other people once and only once.
How many handshakes take place?
2.) A student has some pigs and some chickens.
He finds that together they have 70 heads and 200 legs.
How many pigs and how many chickens does he have?
3.) A well is 10 feet deep.
A frog climbs up 5 feet during the day, but falls back 4 feet at night.
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.

Step-by-step explanation:
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.

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
