A researcher observes and records the height of a weight moving up and down on the end of a spring. At the beginning of the observation the weight was at its highest point. From its resting position, it takes 20 seconds for the weight to reach its highest position, fall to its lowest position, and return to its resting position. The difference between the lowest and the highest points is 6 in. Assume the resting position is at y = 0.

Answer:

5 folders and 5 pens = yes

6 pens and 6 erasers = yes

1 pen and 4 notebooks = no

3 folders and 7 erasers = no

4 folders and 2 notebooks = yes

Step-by-step explanation:

Max total = $10

(5 folders x 1.29) + (5 pens x 0.70)

6.45 + 3.50 = 9.95

(6 pens x 0.70) + (6 erasers x 0.89)

4.20 + 5.34 = 9.54

(1 pen × 0.70) + (4 notebooks × 2.35)

0.70 + 9.40 = 10.10

(3 folders × 1.29) + (7 erasers × 0.89)

3.98 + 6.23 = 10.21

(4 folders × 1.29) + (2 notebooks × 2.35)

5.16 + 4.70 = 9.86

Median: 90

Interquartile range: 9.5

Science: 71, 75, 75, 77, 78, 79, 79, 81, 82

Median: 78

Interquartile range: 5

Answer:

24 would be the correct answer.

Step-by-step explanation:

24 would be the correct answer because 2/3 x 18 + 12 = 24.

Making 2/3 the the fraction that was used and already installed.

Making 18 the number of the already installed applications

Making 12 the number of the additional installed applications.

Answer:

4.5hr

Step-by-step explanation:

v=s/t

t=s/v

432km/96km/hr

4.5 hr

km will will cancelled out

The time taken to travel 432 Km at an average speed of 96 Km/h is 4.5 h

Average speed is defined as the total distance travelled divided by the total time taken to cover the distance.

Average speed = Total distance / total time

Average speed = Total distance / total time

96 = 432 / time

Cross multiply

96 × time = 432

Divide both side by 96

Time = 432 / 96

Time = 4.5 h

Answer:

$60

Step-by-step explanation:

set up a proportion and cross-multiply:

3000/400 = cost/450

c = cost

3,000c = 180,000

c = 180/3

c = 60

Price of the ticket of 450 mile trip = $60.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. It is an operation used for equal grouping and equal sharing in math. Division is the opposite of multiplication.

Division Math Formula

The four important terms used in the division operation are dividend, divisor, quotient and remainder. The formula to calculate the division of two numbers is:

Dividend ÷ Divisor = Quotient + Remainder.

Given,

Ticket cost of 3000 mile trip =  $400

Ticket cost of 1 mile trip = $400/3000

Ticket cost of 450 mile trip = $400 × 450 /3000

                                             = $60

Hence, the cost of 450 mile trip is $60.

Answer:

x = 5

y = 5

Step-by-step explanation:

In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...

2x - x = 5

1x = 5

x = 5

Now we plug that value of x into the second equation

4x - 2y = 10

4(5) - 2y = 10

20 - 2y = 10

-2y = -10

y = 5

Finally, we can see that both x and y have a value of 5.

Answer:

6x+y = 25

3x=14
