Five siblings have a combined age of 195 years. The oldest is 13 years older than the youngest Marc the middle child Anne is fiv
lidiya [134]
This is what someone else answered when someone else asked it. I can't explain it better than this.





So five sibbllings ages are repressented as
a,b,c,d,e
let's have a as youngest and e as oldest in that order
total ages are 195 so
a+b+c+d+e=195
oldest is 13 older thatn youngest
e=13+a
middle child anne (c) is 5 years younger than josie who is an unknow position, we know that she could be d or e or oldest or second oldest
the other 2 are 6 years appart
b and d ar e 6 years appart or b and e are 6 years apart? or is josie the oldest, or second oldest?

second oldes is 42 so
d=42

2 scenarios
if josie is oldest, then see AAAA and if josie is second oldest then see BBBB

AAAA
josie is 13 years older than mark
e=13+a
anne is 5 less than josie
c=e-5
the other 2 are 6 years apart
b+6=d
d=42
subsitute and get
b=36
add and get
78+a+c+e=195
a+c+e=117
e-13+e-5+e=117
3e-18=117
add 18 to both sides
3e=135
divided both sides by 3
e=45
subsitute
a=32
b=36
c=40
d=42
e=45


BBBB
oldest is 13 older than youngest
e=13+a
middle is 5 younger than josie (d)
c=d-5
the other 2 are 6 apart
b=e-6
d=42
subsitute
c=37
subsitute
a+b+37+42+e=195
a+b+e+79=195
subtract 79 from both sides
a+b+e=116
subsitute
e-13+e-6+e=116
3e-19=116
add 19 to both sides
3e=135
divide both sides by 3
e=45
subsitute
45-6=39=b
45-13=32=a
c=42-5=37
this is wrong because b cannot be older than c so therefor AAA si the correct answer


THE ANSWER IS
Josie is the oldest=45
Unknown is second oldest=42
Anne is middle=40
Unknown2 is second youngest=36
Mark is the youngest=32

Deepika on her way to home saw some homeless person sleeping in the park in a winter night. she gave them her canvas area of 551
Romashka [77]
Total area of canvas used in the cunstruction of the tent = 551 - 1 = 550 meters square.
Area of a cone = πr(r + sqrt(h^2 + r^2))
22/7 * 7(7 + sqrt(h^2 + 7^2)) = 550
7 + sqrt(h^2 + 49) = 550/22 = 25
sqrt(h^2 + 49) = 25 - 7 = 18
h^2 + 49 = 18^2 = 324
h^2 = 324 - 49 = 275
h = sqrt(275) = 16.58

The volume of the tent is the volume of a cone with base radius of 7 meter and height of 16.58 meter.
Volume of a cone = 1/3 πr^2h
= 1/3 * 22/7 * 7^2 * 16.58 = 851.3 m^3
