So she had to take $15 out of her paychecks. Bye is able to multiply by four using the number of pencil he can. And so Hannah starts with 127 books. Unlimited access to all gallery answers. So this is what she would've gotten paid based on her hourly wage and the number of hours she worked. She is assisting in processing the Dr. Richard Lodish American School Teaching Collection, a recent acquisition. Enjoy live Q&A or pic answer.

If you have two cavities, you're gonna pay $50 plus 100 times 2, yeah. How many apples are there altogether?
Not everybody purchased a pencil box, though. Learn how to write expressions with variables to describe situations described in word problems. Still have questions? If your question is not fully disclosed, then try using the search on the site and find other answers on the subject another answers. Solved by verified expert. More affluent students might have had a box similar to the boxes in the center, also called scholar's companions. Quills were large feathers with tips that were sharpened to a point and then dipped into ink to write. So how much is each student going to donate? Each package contained 12 pencils. How many pencils are in a pack. How many did Ethan give her? How many pencils can he buy? He gives some to Perry.
Now lets see if this makes sense. Lets check our answer. There are number of pencils. The museum's education collection contains many other types of school equipment from early American education. Number of groups Unknown: Emma has 15 cookies. Hannah's school hosted a book donation. How much money did Sunny earn this week? In the absence of this small knife, a handy pair of sewing scissors would do. SOLVED: ethan bought 4 packages of pencils after he gave 8 pencils to his friends he had 40 pencils. These types of problems involve three quantities which are the number of groups, the size of each group, and the total of all the groups. How many gummy bears does Emma have altogether? SIZE: 8" L x 3" H. Pencil Case.
To determine the solution algebraically, set up and solve the equation 40 = 4x - 8. Gauth Tutor Solution. The average player, the average goals per player is 36 divided by c. Lets do one more of these.
The thinner yellow box in the upper right corner was produced by the American Lead Pencil Company of New York, which later became Venus Pencil. And we have to figure out how much is she going to donate to her school. Slates, crayons, and quills: Back to school supplies of the past. En una competencia de gimnasia, el puntaje final de un atleta? Throughout the 19th century, students also used quills with paper to complete school work and practice penmanship. I still don't get it(28 votes). It has enough room to store your pens, pencils, and other small items like paper clips and erasers.
Computational equation: 5-2=? In these problems, something is always being taken away. There are c players on the Cougars hockey team. As an intern processing this collection, I have become well acquainted with the evolution of pencil boxes, writing implements, and slates used in classrooms throughout American history.
The simple box pictured on the left would have been typical for most students from the mid-19th century. The deluxe middle box comes with its own small ink bottle. When quill tips broke, students would sharpen the quills with a "pen knife. " I know these are not original Blackwing quality, but I hope they are good writers. Write your answer as an expression. Lets do a few more of these.
So this expression right over here, that will tell us the average, that that's the average goals per player. Alright, so lets think about it. Of these pencils, 1/2 were red, and 1/3 were green. So if you see that she earns $12 per hour and she worked for x hours. This seems to make sense.
An additional charge of $100 per cavity.
So, the descriptive studies that generate hypotheses are essential. This one is a little harder to see where exactly the points are. The 3 is the important piece that's going to be my b value for my y intercept. To calculate an isoquant, you use the formula for the marginal rate of technical substitution (MRTS): MRTS( L, K) = − Δ L Δ K = MP K MP L where: K = Capital L = Labor MP = Marginal products of each input Δ L Δ K = Amount of capital that can be reduced when labor is increased (typically by one unit). Curves that intersect are incorrect and produce results that are invalid, as a common factor combination on each of the curves will reveal the same level of output, which is not possible. This y letter and that x letter are going to stay in my equation, so let's go ahead and feel in the blanks. Which equation could generate the curve in the graph below given. The line of best fit provides a math model to make predictions about data points not on the graph and to evaluate the math model's precision. There are two ways to evaluate if the y=mx+b that is derived from the line of best fit is close to representing the data. Below is a collection of data points and the line of best fit. Based on the scatter plot, what is the best prediction for the electricity cost if the temperature for the month is 21°C? The slope also indicates, at any point along the curve how much capital would be required to replace a unit of labor at that production point. So when you're doing that there's a lot of different ways to approach it.
Students may come across curved lines that are not quadratic equations; these expressions may have some other kind of exponent attached to the variable, such as x^3 or even higher expressions. In the given graph the parabola opens downwards and the vertex is in the second quadrant. So here transmission is person-to-person, rather than from a common source. The incubation period for hepatitis ranges from 15-50 days, with an average of about 28-30 days. Most programs interpret the data to give you the value for the slope and intercept. The isoquant curve demonstrates the principle of the marginal rate of technical substitution, which shows the rate at which you can substitute one input for another, without changing the level of resulting output. The vertex's x coordinate (h) is negative, while the they-coordinate (k) is positive. These equations take the form of f(x) = ax^2 + bx + c, and can be solved a variety of ways; students will often be asked to find the solutions, or the zeros, of these graphs, which are the points at which the graph crosses the x-axis. Property 7: Isoquant curves are oval-shaped. If a line's -intercept is. That is, with a 5º change in temperature, the cost changes about $200. The trendline function is Google Sheets can give you the slope and y-intercept. View question - PLEASE HELP!!!PLEASE HELP 4 QUESTIONS!!! WILL UPVOTE!!! Which equation is the BEST fit for the data in the graph? LINK BELOW. Does the answer help you? The slope of the isoquant indicates the marginal rate of technical substitution (MRTS): the rate at which you can substitute one input, such as labor, for another input, such as capital, without changing the resulting output level.
This property falls in line with the principle of the Marginal Rate of Technical Substitution (MRTS). Divide both sides by. Unfortunately, the inverse graphs look similar. Write the equation of a line with intercepts and. Property 4: Isoquant curves in the upper portions of the chart yield higher outputs. Y - 1 = 2x - 2. y = 2x - 1 Based on this, we can see the other options are way off!
If we hadn't been given multiple options, we could have set up the following equation to figure out the third factor: divide by -6. How to find the equation of a curve - Intermediate Geometry. It may also be called an iso-product curve. The isoquant curve is in a sense the flip side of another microeconomic measure, the indifference curve. 16º to 21º the cost will probably change from ≈ $300 to ≈ $600. This 94 second video explains how to go from y = mx + b to an equation with the variables we use in science.
