Jeremiah is saving money for a tutoring job after the first 3 weeks he saved 135$ assume the situation is proportional use the unit rate to write an equation relating the amount saved s to the number of weeks w worked at this rate how much will Jeremiah save after eight weeks? Plz help
Answer:
s = 45w
Step-by-step explanation:
Jeremiah is saving money for a tutoring job.
He saved $135 after 3 weeks.
Therefore, his saving per week = [tex]\frac{\text{Total amount}}{\text{Number of weeks}}[/tex]
= [tex]\frac{135}{3}[/tex]
= $45
If he works for w weeks then at the same rate total amount saved by him will be
= $45w
If this amount is equal to $s then equation that represents the total saving after w weeks will be
s = 45w

To the nearest hundred, what is the greatest whole number that rounds to 2,500
The greatest whole number that rounds to 2,500 to the nearest hundred is 2549.
Explanation:To answer this question, we need to understand how rounding works. When we round to the nearest hundred, any number that falls exactly in the middle or above will round up to the next hundred. Any number that falls below the middle will round down to the previous hundred. The middle point between 2400 and 2500 is 2549. Therefore, 2549 would be the greatest whole number that rounds down to 2500 when rounded to the nearest hundred.

What two integers is the square root of 87 between
The two integers that surround the square root of 87 are 9 and 10.
The first step is to find out the square root of 87:
= √87
= 9.33
Integers are all whole numbers numbering from 1 to infinity so the two integers the square root will be between are the integers immediately below 9.33 and above it. These numbers are:
9 and 109 is immediately below 9.33
10 is immediately above 9.33
In conclusion, the square root of 87 is between 9 and 10.

Find 2 pairs of numbers whose LCM is the product Of The Numbers
Pairs of numbers whose LCM is the same as their product occur with prime numbers or the number one with any other number. For instance, 2 and 3, and 1 and 6 are such pairs of numbers, since their LCM and their product is 6 in both cases.
Explanation:To find two pairs of numbers whose LCM (Least Common Multiple) is the product of the numbers themselves, you need to understand that this will only happen with pairs of prime numbers or the number one with any number. Prime numbers are those numbers that have only two distinct positive divisors: 1 and the number itself. If you multiply two prime numbers, or a number and the number one, the product will be their LCM. For example, if you take the numbers 2 and 3, which are both prime, their product is 6 and so is their LCM. The same thing happens if you take the numbers 1 and 6, whose product is 6, and 6 is also their LCM. So, 2 and 3, and 1 and 6 are two pairs of numbers whose LCM is the product of the numbers.

A semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750. Select the graph that correctly shows the total cost to the company of paying its employees during a year.
Answer:
Option A
Step-by-step explanation:
The semiconductor manufacturing company employs 1000 people average weekly salary of each employee is $750.
So total cost to the company = 750 × 1000
= $750,000 per week.
From the given graphs, the ratio of amount to weeks will show the cost to the company for a week.
Graph A. Cost to the company = [tex]\frac{300\times 1,000,000}{40}[/tex] =
$750,000 per week.
This graph is for 52 week so the correct one.
Graph B. Graph B is same as graph A but data is given for more than 60
weeks so incorrect graph.
Graph C. Ratio of amount and weeks is [tex]\frac{40000000}{30}[/tex]
= $1333333.33 per week So incorrect option.
Graph D. Graph D is same as graph A and B but it is for less than 40 weeks.
So Incorrect graph.

Last week, there were 225 student absences at Johnson High. The circle graph below summarizes them by the day of the week on which they occurred. The central angle for the Tuesday slice is 86.4° . What percentage of the absences occurred on Tuesday?
The percentage of student absences that occurred on Tuesday is approximately 24%.
The circle graph represents the distribution of student absences by day of the week. The central angle for the Tuesday slice is given as 86.4°. To find the percentage of absences on Tuesday, we use the formula: (Central Angle / Total Central Angle) * 100%. In this case, (86.4° / 360°) * 100% ≈ 24%. Therefore, approximately 24% of the student absences occurred on Tuesday.
The central angle represents the proportion of the total absences attributed to each day. A circle has a total central angle of 360°, and the central angle for each day is a fraction of this total. Tuesday's central angle of 86.4° indicates that Tuesday's absences make up 24% of the total absences.
This method applies because the circle graph represents a whole, and each sector's central angle corresponds to its share of the total. Consequently, the calculation accurately reflects the percentage of absences on Tuesday in relation to the entire week.

Final answer:
To solve the addition of 4 yards 8 inches and 6 yards 6 inches, we add yards to yards and inches to inches, resulting in 10 yards 14 inches, which simplifies to 10 yards and 2 inches because 12 inches make a foot, and 3 feet make a yard.
Explanation:
The student's question involves adding two measurements together: 4 yards 8 inches and 6 yards 6 inches. In mathematics, especially in the measurement units topic, it is common to work with both the same and different units when performing calculations. To add these two measurements, we must add the yards together and the inches together separately. Since 1 yard equals 3 feet, this information can be used to convert yards to feet if necessary.
\n\n
First, add the yards: 4 yards + 6 yards = 10 yards. Next, add the inches: 8 inches + 6 inches = 14 inches. Because there are 12 inches in a foot, 14 inches is equivalent to 1 foot 2 inches. Thus, we need to convert this extra foot into yards, knowing that there are 3 feet in 1 yard, so 1 foot = 1/3 yard.
\n\n
We have 10 yards from the initial addition and an additional 1/3 yard from converting the extra foot to yards. Adding these together, we get 10 yards + 1/3 yard = 10 1/3 yards. Since there are no more than 12 inches in the remaining inches part, our final answer in yards and inches is 10 yards 2 inches.
