The two possible measurements given by the student are :
19 cm or 21 cmGiven the Parameters :
Length of stick = 20 centimeters Percentage Error in measurement = 5%The length of the error in measurement can be calculated thus :
Percentage error in measurement × length of stick 20 cm × 5% = 1 cmTherefore the student's measurement can be expressed as :
Actual measurement ± actual length 20 - 1 or 20 + 1 19 or 20Therefore, the possible measurements of the student are 19 or 21 cm

Rico wants to buy the new Madden NFL game. It costs $60.00. He has $24.78 in his bank account. He will also get $20 for mowing his neighbors lawns. Create a number line to represent the situation. ALSO how much more does he need in order to buy the game? *
Answer:
$15.22
Step-by-step explanation:
Given that :
Cost of NFL game = $60
Amount Rico has in bank account = $24.78
Amount earned for mowing lawn = $20
Amount needed more to buy the game :
Total amount Rico has :
Cost of NFL game - (Amount in bank + amount earned for mowing)
$60 - ($24.78 + $20)
$60 - $44.78
= $15.22
Amount needed more to purchase the game = $15.22

Ariana, Boris, Cecile, and Diego are students in the service club. Three of the four students will be chosen to attend a conference. Which choice represents the sample space, S, for this event?
Answer:
S = {ABC, ABD, ACD, BCD}
Step-by-step explanation:
We are told that Ariana, Boris, Cecile, and Diego are students in the service club.
Let's denote their names with letters;
Ariana = A
Boris = B
Cecile = C
Diego = D
We are told that Three of the four students will be chosen to attend a conference. This means that the sample space will be a set showing combination of any 3 out of the 4 students.
Thus, sample space is;
S = {ABC, ABD, ACD, BCD}
Answer:
A

Can anyone help me out with my Math homework plz and also can you provide step by step explanation of the attachment I will give you 20 points:
Answer:
y = -x + 2
Step-by-step explanation:
For any linear equation, the equation of the line can be written in the form 'y=mx+c'. In this form, m is the slope and c is the y-intercept. We can figure out both these things using the graph.
The slope is like the incline/decline and can be found by getting two points on the line, say (x1,y1) and (x2,y2) and using the following formula:
m = (y2-y1) / (x2-x1)
So lets take two points: (-1,3) and (2,0)
m = (0-3)/(2-(-1))
m = -3/3
m= -1
The y intercept (c) is the value for x when the line crosses the y-axis.
From the graph we can see that the line crosses the y axis when x=2
∴ c = 2
Now that we know the slope and intercept, we just sub them into the formula:
y = mx +c
y = -x + 2
Let me know if you have questions :)
Answer:
y equals -x plus 2

Kelley writes the expression n + 2 to model the phrase "Xander studied two more hours than Nandini." Which best explains the accuracy of Kelley's expression?
Answer:
Following are the solution to this question:
Step-by-step explanation:
It was right because the "Two" is "2," "more is" and "+" are two the most hours than Nandini and "n," so 2+n or n+2 is a true, phrase of Nandini's transcription".
Now, this vector n is unknown, so the number of hours Nandini researched should reflect.
Two further hours which Nandini researched Xander. So, Xander studied the number of hours = n + 2 or 2+ n. Kalley has therefore written a correct word.
Answer:
It is accurate. In the phrase “two more hours than Nandini,” “two” is “2,” “more” is “+,” and Nandini’s study time is unknown or “n,” so 2 + n or n + 2 are correct translations.

Step-by-step explanation:
every day is a new day and a new opportunity to change the world no matter how BIG or how small. even if you make mistakes. always remember this though. whatever you put into the world, whether it be good or bad, it will always come back three times.
meaning that when you do something good something three times as good will happen to you. The same is so for bad except it would be 3 times as bad as will happen to you. I hope your day is great and may you do many great things.
The total bill of a meal at a restaurant is 25x – 115. Five
friends agree to split the cost of the meal equally. What
could you do to find the amount that each person must
pay? Explain.
Answer: Divide the whole equation by 5
Step-by-step explanation: You could divide the whole equation by 5 since there are 5 friends. Once you do that you end with the equation 5x - 23, which is what each friend would pay.
Answer:
Sample response: Factor the GCF of five out of the total bill. Divide both terms of the expression by 5. The result is 5x – 23, which is the expression that can be used to find the amount each person pays.
Step-by-step explanation: (you may want to reword it)

What is the total cost of a pair of jeans that are priced $50.00 if there is 7 1/2% sales tax?
$57.50
$53.75
$55.50
Answer:
See below.
Step-by-step explanation:
Divide the percentage to find the decimal form.
[tex]\frac{7.5}{100} =0.075[/tex]
Multiply the total by the percentage.
[tex]50*0.075=3.75[/tex]
Add that to the total.
[tex]50 +3.75=53.75[/tex]
Answer: [tex]53.75[/tex]

-2x-5=4 solve for x and please tell me how you got it
Answer:
x = -9/2 or -4.5
Step-by-step explanation:
-2x-5=4
Add 5 to each side
-2x-5+5=4+5
-2x = 9
Divide each side by -2
-2x/-2 = 9/-2
x = -9/2 or -4.5
Michael has a set of 24 math problems to do for homework. Michael completed 1/4 of his homework in 3/4 of an hour. If he continues at this rate , what fraction of his homework would he complete in one hour ? A. 3/8 B. 2/3 C. 4/3 D. 3/2
Given:
Total number of problems = 24
Michael completed [tex]\dfrac{1}{4}[/tex] of his homework in [tex]\dfrac{3}{4}[/tex] of an hour.
To find:
What fraction of his homework would he complete in one hour.
Solution:
We have,
Part of work done in [tex]\dfrac{3}{4}[/tex] of an hour [tex]=\dfrac{1}{4}[/tex]
Part of work done in an hour [tex]=\dfrac{4}{3}\times \dfrac{1}{4}[/tex]
[tex]=\dfrac{1}{3}[/tex]
Therefore, he complete [tex]\dfrac{1}{3}[/tex] of his homework in 1 hour. Hence, all options are incorrect.
How can you find the slope from a table?
Answer:
you find slope from a table by taking any two points. the left side is the input of the table, the x, and the right side is the output the y. whenever you're finding the points to do slope, they must be correlated.
__x__|__y__
___2_|__4___
__3__|___6__
so if you want to choose 2 for the x input then you must choose the 4 as the y output.
After choosing the two points, (2,4) and (3,6), you need to find the slope which is y-y/x-x. so in this case it's 6-4/3-2. after subtracting you get, 2/1 which if you simplify, it's 2. Or you divide which is also 2. I hope this helped.

Find the measure of the missing angles.
Answer:
153* for both
Step-by-step explanation:
This makes a circle, which is 360*. One angle is given, and it is 27*. If the angle on the opposite side is the same, the total degrees so far would be 54.
Say b and c were equal. Then, the remaining 306* would be split even among them. 306/2 is 153.
Therefore, 153* is the correct answer.

Una limusina cuesta $ 85 para alquilar por 3 horas más un 7% de impuesto sobre las ventas. Cúal es el costo total
alquilar una limusina por 6 horas?
Answer:
$181.9
Step-by-step explanation:
Si cuesta 85 dólares por 3 horas, queremos duplicarlo para obtener la cantidad por 6 horas, que es 170 dólares. Esto es antes del impuesto a las ventas. Puede encontrar la cantidad después del impuesto a las ventas multiplicando 170 por 1.07. Hace esto porque el 100 por ciento del costo sería 170 por 1 y el 7 por ciento es .07, por lo que si desea el 107 por ciento del costo, debe hacerlo 170 por 1.07. Esto funciona porque toma el 7 por ciento de 170 y lo agrega al costo total. También puede hacer esto 170 veces .07. Luego suma el producto a 170. 181,9 es la respuesta final.
English- If it costs 85 dollars for 3 hours we want to double that to get the amount for 6 hours which is 170 dollars. This is before sales tax. You can find the amount after sales tax by multiplying 170 by 1.07. You do this because 100 percent of the cost would be 170 times 1, and 7 percent is .07, so if you want 107 percent of the cost you want to do 170 times 1.07. This works because it takes 7 percent of 170 and adds it to the total cost. You could also do this by 170 times .07. Then add the product to 170. 181.9 is the final answer.
