Answer:
father = 32 s = 5 y/o
Step-by-step explanation:
f s = 160 ====> s = 160/f
f+4 = 4 ( s+4)
f + 4 = 4 (160/f +4)
f + 4 = 640/f + 16
f^2 + 4f = 640 + 16 f
f^2 -12f - 640 = 0 Use Quadratic formula to find f = 32 then s = 5
Answer:
C) 4 pencils for each student
D) 8 students per team
Step-by-step explanation:
A unit rate is the number of unit of the first type of a quantity corresponding to one unit of the second type of quantity.
That is, if a and b are two quantities,
Then, unit rate of quantity a = x units of 'a' per 1 unit of 'b' or x units of 'a' for 1 unit of 'b'
By the above statement,
The example of unit rates from the given options are,
4 pencils for each student,
8 students per team
The answer is number 3, an=9.5+2(n-1)
Pythagorean theorm is a^2+b^2=c^2
so 10^2+ 24^2 =c^2
100+576=c^2
676=c^2
26=c
