Answer:
7/10 hours
Step-by-step explanation:
her first assignment took 1/2 hour
her second assignment took 1/5 hour
so in total she took 1/2 + 1/5
we need to find a common denominator
the lcm(2,5)=10
so multiply 1/2 by 5/5 to obtain 5/10
multiply 1/5 by 2/2 to obtain 2/10
5/10 + 2/10 = 7/10
Answer: D
Step-by-step explanation:
Answer:
it answer is 3 because it is trigonometry
1) given ,
4x-24=1000
=> 4x = 1000+24
=> 4x = 1024
=> x = 256
2)Given , 7x= 343
=> x = 343/7
=> x = 49
3) given , x^4 = 4096
=> x = fourth root of 4096
=> x = 8
