Your parents gave you $20 to spend at the book fair. You are getting the new Diary of the Wimpy kid book that costs $8.99/ If pencils and erasers cost $0.79 each, what is the maximum you can buy with the money provided?

Answers

Answer:

You can buy a maximum of 13 erasers/pencils.

Step-by-step explanation:

Your total is 20 dollars. The book cost 8.99, so you take away that amount from 20, getting you 11.01. You have $11.01 left. Then you divide your total (11.01) by the price of each eraser (0.79). This gets you 13.9367088608. Since thats not an even number, you have to round down because you don't want a broken pencil?eraser.

Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please

Answers

Answer:

Constant of variation: 1/4

Slope of the line: 1/4

Step-by-step explanation:

The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Answers

Answer:

A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla

entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100

en mi primera ecuación seria: 4X + 3Y = 14.100

ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla

en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:

primera ecuación: 4X + 3Y = 14.100

segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1

al sumarlas obtengo como resultado: -5X = -12

resolviendo esa ecuacion obtengo que X=  

X=2.4

luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100

reemplazando seria: 4 x (2.4) + 3Y =14.100

9.6 + 3Y = 14.1000

3Y= 14.100 - 9.6

Y=  

Y=1.5

entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $

Which ratio is the simplest form of 68:84?
A 2:3
17:21
34:42
D 21:17

Answers

Answer:

17:21

Step-by-step explanation:

The ratio 68:84 in its simpliest form is;

68:84 (Since it can divided by 2 perfectly);

34:42 (We also divide this by 2 )

17:21

17:21 is the final answer and it can be divide any further. Since 17 is a prime number, it can't be divided and also 21 can be divided by 3 but 17 can't be divided by 3 so we leave the final answer like that.

Howard bought 3/5 pound of granola. He divided the
granola evenly among 4 friends. How much granola did
each friend get?

Answers

Answer:

Step-by-step explanation:

So because Howard wants to divide the granola evenly among all of his friends, we have to divide the amount of pounds he has by the number of friends he has.

(3/5) / 4

Dividing by four is the same as multiplying by the reciprocal of 4 which is 1/4.

So (3/5) * (1/4) is 3/20 which is .15 pounds

A tire manufacturer knows that 5% of tires contain a defect, and the presence of a defect is independent from tire to tire.
What is the probability that if 5 tires are inspected, exactly 1 has a defect?
Round to 3 decimal places.

Answers

Answer:

the answer is 0.204

Step-by-step explanation:

The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

How to determine the probability?

The probability that a tire is defect is given as:

p = 5%

The required probability is then calculated using:

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

Where:

n = 5 --- number of tires

x = 1 ---number of tires with defect

So, we have:'

[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]

This gives

[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]

Evaluate the product

P(1) = 0.204

Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

Brainliest!!!!! Please hurry!! This is a lab for science can you help with punctuation errors? Also where it says figures I have pictures :) (I am in 7th grade btw so no hate)Leaf labPurpose: Find out if the leaf area of a given tree is bigger on the North or the Southside. Learn more advanced statistical analysis.Research: To find the area of an irregular shape its whole + part which is whole plus part divided by 2. The shape of the leaf will be traced. They are affected by the Earth's tilt and the sun because we are in the North Hemisphere.Figure 1 is an example of the Earths tilt and how the sun gives a certain amount of heat to different parts of the Earth. The south gets more sun its because the leaves burn while the north leaves get less sun. The north leaves are thinner but bigger in area than the leaves that get a lot of suns. This makes them smaller or bigger because one side might get more sun which makes north leaves bigger.Hypothesis: The leaves on the Northside are bigger.Procedure:1. Collect 35 leaves from the Northside and 25 leaves from the Southside.2. A tree that is not in shade.3. Press the leaves flat.4. Trace the leaves onto graph paper using both sides of the page keeping North and South separate.5.Count whole (w) and partial squares (p) and calculate the area of each leaf in squares 6. with the equation A= W+ P.Figure 2 is an example of the equation A= W+ P. There are 4 wholes and 8 parts so the area is 8 inches squared because 4+ 8= 8.7. Create a north and South leaf data table.8. Discard leaves afterward.9. Put the leaf area in order from smallest to greatest in each table.10. Find the mean, median, mode of the 2 data sets as well as the entire range of 50 leaf data sets.11.Create a histogramUse the range to find the size of 7 bins. USe the nearest whole numberSort leavesCount leaves and creates a chart12.Create histograms of individual data using Microsoft Excel or google docs 5. Results: The north's side leaves are bigger than the south side by a few a lot, 6. Conclusion: It was a warm sunny day and windy. The experimenter gathered 25 leaves from the North and South sides with all different sizes and colors. The hypothesis was supported based on the data collected. One reason why it was supported was that the North overall average was greater than the South. The Northside leaves are greater is that it is proven by facts. If someone compared a random south leave to a random north leaf, most times the North would be bigger because the probability of getting a big leaf is higher for North rather than South. The second piece of evidence from my data is that the South bin had more leaves in smaller bins while the North bin had an equal amount of leaves in the high and low bins. The third piece of evidence is that the Northside leaves had a bigger average than the South leaves. Also, the Southside had the smallest leaf while the Northside had the biggest leaf. The entire group also supported this. 7. Errors and ways to improve: Try to get different trees and instead of picking a few leaves in a certain area in the north and south, pick random ones. Also, gather more and different leaves. Different weather conditions could affect the leaves.Figure 3, is the north bin where most of the leaves are bigger.Figure 4, the south bin where most of the leaves are smaller.Figure 5, the class north bin where some most leaves are small but some are big.Figure 6, the class south bin where mostly all of the leaves are small.Figure 7 is the tree used to pick leaves off. 1.
