Answer:

2 hours

Step-by-step explanation:

you can write two linear equations and then set them equal to each other to see when they intersect. so for the first equation which will be representing the junior space cadets distance from his house. this can be written as

d = 50t + 50

where t represents time and d represents distance. there is 50 being added to the equation since he had already been traveling for an hour

the second equation which will represent his sister Gwen can be represented as

d = 75t

Now we set them equal to each other

50t + 50 = 75t

50 = 25t

2 = t

Could someone please help me answer this math question
Greeley [361]

<u><em>Explanation</em></u>

5 students got 6 mark each,                                                                                         4 students got 7 marks each,                                                                                       7 students got 8 marks each,                                                                                            10 students got 9 marks each                                                                                   and 4 students got 10 marks each.

(a)  <u>Range is the difference of highest mark and lowest mark.</u> Here, the highest mark is 10 and lowest mark is 6.

So, the range of mark = 10-6 = 4

(b) Total number of students in the group = 5+4+7+10+4= 30

(c)   Mean is the <u>simple average.</u> So, for finding the Mean, we will divide the total marks obtained by all students by the total number of students.

Total marks obtained by all students

= (6*5)+(7*4)+(8*7)+(9*10)+(10*4)\\ \\  = 30+28+56+90+40 = 244

So, the Mean mark of the group =\frac{244}{30}=8.13333....

a = 2πr² + 2πrh

a - 2πr² = 2πrh

(a - 2πr²)/2πr = 2πrh/2πr

h = (a - 2πr²)/2πr
