The other quantity needed to calculate the average speed is time.
What is average speed?
Average speed is the total distance travelled per time. It is how fast an object moves with respect to time.
Average speed = total distance / total time
For example, if the distance travelled is 100km and the total time is 10 hours, average speed is 10 km/hr (100 / 10).

students chose red, and 33 students chose yellow.
Greg concluded that the students at the middle
school have a preference of the color red. Is his
inference correct? Why or why not?
Answer:
No, he is not correct because red and yellow got the same amount of votes when it came to adding them up.

Which expression correctly represents "nine less than the quotient of a number and four, increased by three"? StartFraction n Over 4 EndFraction minus 9 3 StartFraction 4 Over n EndFraction minus 9 3 9 minus StartFraction n Over 4 EndFraction 3 9 minus StartFraction 4 Over n EndFraction 3.
Answer:
n/4-9 +3
Step-by-step explanation:
to answer this question we have to analyze the information given.
The quotient of a number means the result of the division of 2 numbers.
In this case the numbers are: a number (n) and 4 . n/4
Nine less than that quotient means we have to subtract 9 to the quotient.
n/4-9
Increase by three: we simply have to add 3
n/4-9 +3

Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°

John walked 9 5/8 miles at an average speed of 1 3/4 MPH. How long did it take John to walk this distance?
Answer:
5 hours and 30 minutes
Step-by-step explanation:
Convert all fractions to decimals for easier division
9 and 5/8 = 9.625
1 and 3/4 = 1.75
Then divide 9.625 by 1.75 to get the hours amount
9.625 / 1.75 = 5.5
0.5 of an hour is 30 minutes, so the final answer is 5 hours and 30 minutes
Answer:
5.5 hours
Step-by-step explanation:
9.625/1.75=5.5hr

A plant has an initial height of 2 inches and grows at a constant rate of 2 inches each month. A second plant that also grows at a constant rate has an initial height of 1 inch and is 29 inches tall after 1 year. After how many months are the plants the same height?
Answer:
Answer:4.8 monthsStep-by-step explanation:First, let's write down the information that we are given.Plant A: Initial Height: 3 in.Constant Rate of Growth (CRG): 2in/month (2 inches per month)Plant B:Initial Height: 1 in.CRG: 29in/year (29 inches per year)We can see that Plant B grows 29 inches per year, so lets convert Plant B's 'CGR' to months.Plant B - Divide by 12 (12 months in a year)29/12 in/yearNow, Lets put these into equations:Plant A: y = 2x + 3Plant B: y = 29/12 x + 1Now, set these two equations together and solve for x.2x + 3 = 29/12 x + 12 = 5/12 x4.8So, after 4.8 months, the plants will be the same height.

WILL GIVE BRAINLY PLEASE HELP!!!!!! In this triangle, what is the value of x? enter your answer, rounded to the nearest tenth, in the box.
Answer:
x ≈ 67.1
Step-by-step explanation:
The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(x°) = 28/72 = 7/18
The angle is found from the cosine using the inverse cosine function:
x° = arccos(7/18)
x° ≈ 67.1°

Answer:
(3, -6)
Step-by-step explanation:
Both equations are equal to y, so you can make them equal to each other:
-2x = 5x-21
Get the same terms on the same side by subtracting 5x from both sides"
-7x = -21
Get x alone by dividing both sides by -7:
x = 3
The simplest way to find y is by filling in 3 for x in the first equation:
y = -2(3)
Multiply:
y = -6
Check your answer by filling in 3 for x in the second equation:
y = 5(3) - 21
Multiply:
y = 15 - 21
Subtract:
y = -6
To check both answers together, fill in 3 for x and -6 for y in both equations (although we already checked both answers above):
-6 = -2(3)
-6 = -6
-6 = 5(3) - 21
-6 = 15 - 21
-6 = -6

To solve this we first of all need to find the distances travelled by both Vaimiti and Jabril and then we will find their difference...
Let's start solving ~

Distance covered by Vaimiti ⤵️
[tex] \tt \leadsto \: Distance = Speed × Time[/tex]
Vaimiti's speed = 1.1 m/s
Time taken by her = 25 minutes = 25×60 = 1500 seconds
[tex] \sf \leadsto \: Distance = 1.1 \times 1500[/tex]

Distance covered by Jabril ⤵️
[tex] \tt \leadsto \: Distance = Speed × Time[/tex]
Jabril's speed = 1.3 m/s
Time taken by her = 30 minutes = 30×60 = 1800 seconds

Difference between distances travelled by them↯
Distance travelled by Vaimiti = 1650 m
Distance travelled by Jabril = 2340 m
[tex] \bf\nRightarrow \: Difference = 2340 - 1650[/tex]
