Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.
He has 7272 pencils and 2424 calculators and he must use all of the pencils and calculators.
If Zayed creates the greatest number of identical packages possible, how many pencils will be in each package?
Answer:
He should have 3 pencils in each package.
Step-by-step explanation:
you would do 7272 divided by 2424 so that there is a pencil for each calculater.
Answer:
The number of pencils in each package is 3.
Step-by-step explanation:
The total number of pencils = 7272
The number of calculators = 2424
He has to create greatest number of package and the condition is he has to use all the calculator and pencils.
The minimum number is 2424 which is number of calculators, So he can create maximum of 2424 packages. He must use all 7272 pencils.
So to find the number of pencils, we need to divide the number of pencils by the number of calculators.
The number of pencils in each package = [tex]\frac{7272}{2424}[/tex] = 3
The number of pencils in each package is 3.

Answer:
5.5 h
Step-by-step explanation:
There is an inverse relationship between the time (t) it takes to do a job and the number (n) of workers (the more workers. the faster the work gets done).
t = k/n Divide both sides by n
t/n = k
If we have two different numbers of workers, then
t₁/n₁ = t₂/n₂ Multiply each side by n₂
t₂ = t₁ × n₁/n₂
t₂ = 22 × 1/4
t₂ = 5.5 h

Answer: This is a function
There are no repeated x values. Each x value is paired with exactly one y value. If you had an input of something like x = 3 lead to y = 5 and y = 8 at the same time, then it wouldn't be a function.
If you want, you can graph all five of these points, as is shown in the attached image below. You'll notice that it is impossible to draw a vertical line through more than one of these five points. The graph therefore passes the vertical line test to visually confirm we have a function.

bring the fraction 12/y−x to a denominator of x−y
i would really appreciate it thx
Final answer:
To convert the fraction 12/(y-x) to have a denominator of (x-y), you multiply both numerator and denominator by -1, resulting in the fraction -12/(x-y).
Explanation:
To bring the fraction 12/(y−x) to a denominator of (x−y), realize that y−x is essentially -(x−y). This means we can multiply the numerator and denominator by -1 to get the desired denominator. The step-by-step process would be:
Begin with the original fraction: 12/(y−x).Recognize that y−x is the negative of (x−y). So, y−x = −(x−y).Multiply the numerator by -1 and the denominator by -1: (12 * -1)/((y−x) * -1).This simplifies to: -12/(x−y).Now, the fraction 12/(y−x) is expressed with the desired denominator (x−y) as -12/(x−y).

4x = 30
/4 /4
x = 7.5
the shadow of the woman will be 7.5 feet.
What is proportionality?the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Given, A 5-foot woman stands near a 4-foot cello case. The cello case casts a shadow that is 6 ft long.
Since the shadows are made because of the light of the Sun. thus we will assume the Angle of Light source will be the same.
So In angles are the same then
Base and perpendicular will be in proportion as per the Pythagorean theorem
So,
Women's height/cello's height = Women's shadow/cello's shadow
=> 5/4 = women's shadow/ 6
=> women's shadow = 7.5 ft
Therefore, the shadow of the woman will be 7.5 feet.

a laptop computer is purchased for $950. after each year the resale decreases by 30%. what will the resale value be after 5 years?
Answer: 153
I think the answer is 153 because you have to do 950-30 and then divide it by 30 after you do that you multiply it by 5 and get 153.000000...
So you round it to the nearest whole number and that's 153
The resale value of a laptop after 5 years with a 30% decrease in value each year, follows the step-by-step calculation provided.
The resale value of a laptop after each year decreases by 30%. To calculate the resale value after 5 years, we need to consider the decreasing value each year:
After 1 year: $950 - $950 x 30% = $665
After 2 years: $665 - $665 x 30% = $465.50
After 3 years: $465.50 - $465.50 x 30% = $325.85
After 4 years: $325.85 - $325.85 x 30% = $228.10
After 5 years: $228.10 - $228.10 x 30% = $159.67

Final answer:
Joyce has read 9/10 of her book over the course of three days by adding together the fractions of the book she read each day and simplifying the result.
Explanation:
To determine the part of the book Joyce has read over the three days, we need to add the fractions representing the parts read each day. On Monday, Joyce reads 1/6 of her book, on Tuesday she reads 2/5, and on Wednesday she reads 1/3. Thus, we add these fractions together.
The Least Common Denominator (LCD) for 6, 5, and 3 is 30. We convert each fraction to have this common denominator:
1/6 = 5/302/5 = 12/301/3 = 10/30Now, we sum the fractions:
5/30 + 12/30 + 10/30 = (5 + 12 + 10)/30 = 27/30
27/30 can be simplified to 9/10 after dividing both numerator and denominator by 3. So, Joyce has read 9/10 of her book over the three days.

How do you solve this absolute value equation and inequality problem?
Answer:
r < -7 or r > 10
Step-by-step explanation:
-2|3 - 2r| < -34
|3 - 2r| > 17 (Note the inequality sign flips because we divide by negative)
Now we split it up into 2 inequalities :-
3 - 2r > 17
-2r > 14
r < -7 (answer)
and
3 - 2r < -17
-2r < -20
r > 10 (answer).
Answer:
r > 10 or r < - 7
Step-by-step explanation:
isolate the absolute value by dividing both sides by - 2
| 3 - 2r | > 17
Inequalities of the type | x | > a always have solutions of the form
x < -a OR x > a, hence
3-2r < - 17 or 3 - 2r > 17 ( subtract 3 from each interval )
- 2r < - 20 or - 2r > 14 ( divide both intervals by - 2 )
Remembering to reverse each inequality symbol as a result of dividing by a negative quantity.

13.09 to the nearest tenth
Answer:
13.1
Step-by-step explanation:
Note the place values
1 : tens
3 : ones
. (decimal point)
0 : tenths
9 : hundredths.
Solve for the tenths place value. Note the hundredth value, it is a 9
Because 9 is greater than 5, round up.
13.09 rounded to the nearest tenth is 13.1
~
To round 13.09 to the nearest tenth, we increase the tenths place by 1 since the hundredths place is 9. Thus, the number rounds up to 13.1.
The question asks to round the number 13.09 to the nearest tenth. To do this, we look at the hundredths place, which is 9 in this case. Since the digit in the hundredths place is 5 or more, we round the digit in the tenths place up. Therefore, 13.09 rounded to the nearest tenth is 13.1.
Solve for u. I need a little help.
Answer:
value of 'u'= -54
Step-by-step explanation:
[tex]30 = -\frac{5}{9}u[/tex]
To eliminate any number , we always do opposite operation
To remove denominator 9, we multiply both sides by 9
[tex]30*9 = -\frac{5}{9}*9*u[/tex]
270 = -5u
To remove -5 we divide by -5 on both sides
[tex]\frac{270}{-5} = \frac{-5u}{-5}[/tex]
-54= u

One store sells milk for $3.00 per gallon. A second store sells milk for $0.80 per quart. Formulas If you need two gallons, which store should you buy from?
Answer:
You should buy from the first store
Step-by-step explanation:
Since there are 4 quarts in a gallon, we will need to multiply .80 by 8 to figure out how much it costs for 2 gallons. This will be $6.40 for the second store, and in order to find out how many the first store offers, we multiply 3 by two, which is six.
So, the first store charges $6.00 for two gallons, and the second store does $6.40 for two gallons of milk
Answer:
The first store.
Step-by-step explanation:
This is easy, multiply 0.80 x 4 since there are four quarts in a gallon. You get 3.20. Then, multiply 3.20 by 2 to get 6.40 and 3.00 by 2 to get 6.00.
So
Store number one: $6.00
Store number two: $6.40

On Sunday, a local hamburger shop sold a combined total of 378 hamburgers and cheeseburgers. The number of cheeseburgers was sold 2 times the number of hamburgers. How many hamburgers were sold?
Answer:
The number of hamburgers sold was 126.
Step-by-step explanation:
Let h = number of hamburgers sold
let c = cheeseburgers sold
c+h = 378
c = 2h
Substitute c =2h into c+h =278
c+h =378
2h+h = 378
Combine like terms
3h = 378
Divide by 3
3h/3 =378/3
h =126
The number of hamburgers sold was 126.
Final answer:
To determine how many hamburgers were sold, we set up a system of equations and found that 126 hamburgers were sold.
Explanation:
The local hamburger shop sold a combined total of 378 hamburgers and cheeseburgers. We are told that the number of cheeseburgers sold was 2 times the number of hamburgers. We can set up a system of equations to solve this problem using h to represent the number of hamburgers and c to represent the number of cheeseburgers:
h + c = 378 (the total number of burgers sold)
c = 2h (the number of cheeseburgers was 2 times the number of hamburgers)
Now let's substitute the second equation into the first to solve for h:
h + 2h = 378
3h = 378
h = 378 ÷ 3
h = 126
Therefore, the number of hamburgers sold was 126.

c. x=-71, y=-5, z=11
d. x=11, y=-5, z=-71
d. x=11, y=-5, z= -71
To solve the given system of equations, we use the method of substitution. The solution is x = 11, y = -5, z = -71.
Explanation:To find the solution of the given system, we can use the method of substitution.
From the first equation, we have x = -3y - 4. Substituting this value for x in the second equation, we get -3y = 2(-3y - 4) - 7.
Solving this equation, we find y = -5. Substituting this value of y back into the first equation, we can solve for x. Plugging in y = -5, we get x = 11. Substituting these values for x and y in the third equation, we can find z. Plugging in x = 11 and y = -5, we get z = -71.
Therefore, the solution to the system is x = 11, y = -5, and z = -71.

Ryan bought a guitar for $475.45. If he makes $9.25 per hour at his job, how many hours did he have to work to pay for the guitar? Explain how to find the answer and check it.
Answer: 51.4 hours
Step-by-step explanation: To figure out the answer to this equation you would divide the cost by how much you make, 475.45÷9.25=51.4
Ryan would need to work approximately 51.51 hours to earn enough money to pay for the guitar.
To find the number of hours Ryan had to work to pay for the guitar, we need to divide the cost of the guitar by his hourly wage.
Divide $475.45 (cost of the guitar) by $9.25 (Ryan's hourly wage):
$475.45 / $9.25
≈ 51.51
This calculation shows that Ryan would need to work approximately 51.51 hours to earn enough money to pay for the guitar.
To check the answer, multiply the number of hours (51.51) by Ryan's hourly wage ($9.25):
51.51 x $9.25 ≈ $476.33
The result is close to the cost of the guitar ($475.45), allowing for small discrepancies due to rounding or decimal approximations. Therefore, this confirms that Ryan would indeed need to work around 51.51 hours to cover the cost of the guitar.

Given question is incomplete; here is the complete question.
How did the temperature change if: at first it increased by 25 % and then decreased by 40% ?
Temperature will finally decrease by 25%.
Let the initial temperature is x° C,
If the temperature is increased by 25%,
Then the final temperature = x° + 25% of x°
= [tex]x+\frac{25x}{100}[/tex]
= [tex]x+0.25x[/tex]
= [tex]1.25x^\circ[/tex]
Followed by the decrease in temperature by 40%,
Then final temperature = 1.25x° - 40% of (1.25x°)
= 1.25x° - 0.5x°
= 0.75x°
Therefore, percentage decrease in temperature from initial temperature x°,
Percentage decrease = [tex]\frac{x^\circ-0.75x^\circ}{x^\circ}\times 100[/tex]
