Answer:
Kendal will be 60 meters away from the library after 80 seconds and again after 100 seconds.
Step-by-step explanation:
6s -540 = 60 or 6s - 540 = -60
First equation
addition property of equality: 6s -540 + 540 = 60 + 540
simplify: 6s = 600
division property of equality: 6s/6 = 600/6
simplify: s = 100
Second equation
addition property of equality: 6s -540 + 540 = -60 + 540
simplify: 6s = 480
division property of equality: 6s/6 = 480/6
simplify: s = 80

[tex]y=x^{2} -5x+7\\y=2x+1[/tex]
Answer:
x = 6, and x = 1
Step-by-step explanation:
If each expression equals y, the simplest approach would be to equate them;
x^2 - 5x + 7 = 2x + 1 => Isolate all the terms on one side
x^2 - 5x - 2x + 7 - 1 = 0 => Combine like terms
x^2 - 7x + 6 = 0 => solve using quadratic equation
x = ( - (- 7) + √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1
= 7 + √25 / 2 = 7 + 5 / 2
= 6
x = ( - (- 7) - √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1
= 7 - √25 / 2 = 7 - 5 / 2
= 2 / 2 = 1

Devon earns $35 per hour for a regular 40-hour work week. Sometimes, he works over 40 hours a week and earns "double time" for the extra hours worked. (That means that his hourly rate for the additional hours over 40 hours per week is double his normal hourly rate.) If Devon works 48 hours in one week, how much would he earn that week?
Answer:
1960
Step-by-step explanation:
40 times 35 = 1400
8 times 2 times 35 = 560
1400+560=1,960$
When Devon works for 48 hours in one week the total amount he earned that week is equal to $1960.
To calculate Devon's earnings for the week when he works 48 hours,
Consider his regular pay for the first 40 hours and then the "double time" pay for the additional 8 hours.
Regular pay for 40 hours: Devon earns $35 per hour for a regular 40-hour work week.
Regular pay = $35/hour × 40 hours = $1400
Overtime pay for the additional 8 hours: Devon works 48 hours in total, so he works 8 hours over the regular 40-hour work week.
For these 8 hours, he earns "double time," which means his hourly rate is doubled.
Double time rate = 2 × $35 = $70/hour
Overtime pay
= Double time rate × Number of overtime hours
= $70/hour × 8 hours
= $560
Total earnings for the week: To find the total amount earned in the week, add the regular pay and the overtime pay.
Total earnings
= Regular pay + Overtime pay
= $1400 + $560
= $1960
Therefore, if Devon works 48 hours in one week, he would earn $1960 that week.

1. twice the square of the sum of a number and 3 is 98.find the number
Answer:
Step-by-step explanation:
Let the number be x.
twice the square of the sum of a number and 3 is expressed as;
2(x+3)²
If the expression is equal to 98, then;
2(x+3)² = 98
divide both sides by 2;
2(x+3)²/2 = 98/2
(x+3)² = 49
square root both sides
√(x+3)² = √49
x+3 = ±7
x = ±7-3
x = 7-3 or -7-3
x = 4 or -10
Hence the number is 4 or -10
The number is -4 or 10
Let n represent the unknown number
The following equation can be used to summarise the information given in the question
2 × n² = 98
The first step to take in order to determine the value of n is to divide both sides of the equation by 2
n² = 98/2
n² = 49
The second step is to determine the square root of both sides of the equation
n =√49
n =-7 or +7
The number = - 7 + 3 = - 4 or 7 + 3 = 10

A map shows a section of Interstate 94 that forms a straight line. A family plans to drive 72 miles on Interstate 94 from St Paul, MN to Elk Mound, WI. They drive for 20 miles, and then decide they will stop halfway through their trip to eat. How much farther do they need to drive before they stop for dinner?
Answer:
16 miles
Step-by-step explanation:
Given that:
Total distance of the trip = 72 miles
They have decided to stop half way their trip i.e. they will stop at a distance [tex]\frac{72}{2} =36[/tex] miles from the starting point.
Also, given that they have already traveled for 20 miles.
To find:
How much farther do they need to drive before they stop for dinner?
Solution:
Distance already covered = 20 miles
Distance to be covered before stopping for dinner = 36 miles
Distance to be covered more = Total distance to be covered before stopping - Distance already covered
[tex]\Rightarrow 36-20 =\bold{16\ miles}[/tex]

The answer is "d" x= r-p / g
Step-by-step explanation:
First let's get rid of the "p" term on the left-side. After you've done that, you have to get rid of the g term. So you divide the x term by the g-term, you do this to both sides.
Cleo and jandi are having a Halloween party. They have 3 1/2 pounds of candy to divide into 14 goodie bags. How much candy will be in each bag?
Answer:
1/4 pound(s) of candy in each bag
Step-by-step explanation:
3 1/2 (pounds of candy) ÷ 14 (goodie bags) = ?
To make this easier let's turn 3 1/2 into a improper fraction and flip 14/1 (14/1 to 1/14):
3 1/2 = 7/2 14/1 = 1/14
Now we multiply:
7/2 x 1/14 = 7/28 = 1/4
(When you divide fractions, you can flip the second fraction and multiply and get your answer. Remember to simplify once you get your answer!)

Answer:
9/5
Step-by-step explanation:
The slope between the two points can be found by ...
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5
The slope of the line is 9/5. Perhaps this is a match to choice A.
Answer: 9/5
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5

A new underground rollercoaster is being installed. The height of the rollercoaster in feet throughout the underground section is modeled by the equation h(d) = 0.15d2 – 1.5d, where d represents horizontal distance in feet. What's the height of the rollercoaster 6 feet horizontally through the underground section?
Answer:
3.6 feet
Step-by-step explanation:
The height of the rollercoaster in feet throughout the underground section is modeled by the equation :
[tex]h(d) = 0.15d^2 - 1.5d[/tex] ....(1)
We need to find the height of the rollercoaster 6 feet horizontally through the underground section.
Put d = 6 feet in equation (1) as follows :
[tex]h(6) = 0.15(6)^2 - 1.5(6)\\\\h=-3.6\ \text{feet}[/tex]
or
h = 3.6 feet
So, the height of the rollercoaster 6 feet horizontal through the underground section is 3.6 feet.

A school has 625 students and 25 teachers. Which of these statements is true based on this information? A) The school has a ratio of 5 students to 1 teacher. B) The school has a ratio of 5 teachers to 1 student. C) The school has a ratio of 25 students to 1 teacher. D) The school has a ratio of 25 teachers to 1 student.
The statement that is true based on the information that a school has 625 students and 25 teachers is that the school has a ratio of 25 students to 1 teacher.
According to the question,
We have the following information:
A school has 625 students and 25 teachers.
Now, we have to find the ratio using the given information.
Ratio of students to the teachers can be better understood in simple terms as the number of the students divided by the number of the teachers.
Ratio of students to the teachers = Number of students : number of teachers
Ratio of students to the teachers = 625:25
Dividing both the numbers by 25,
Ratio of students to the teachers = 25:1
So, the school has a ratio of 25 students to 1 teacher.
Hence, the correct option is C.

Use the formula C = 5 (F – 32). To determine which temperature is hotter.
30° Celsius or 85° Fahrenheit. Write just the number as your answer.
Answer:
Step-by-step explanation:
The formula u have written is incorrect. It should be C = [5 (F-32)]÷9.
To identify which is hotter, you need to bring both the values either in celsius or in Fahrenheit.
Let's convert 85°F to celsius:
C = [5 ( F - 32 )] ÷ 9
C = [5 ( 85-32 )] ÷ 9
C = [5 (53)] ÷ 9
C = 29.4 °C
thus 30°C is hotter than 85°F
