This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.
Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours
Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour
Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours
Answer:
50
Step-by-step explanation:
Sum Even numbers
n = 50
d = 2
a1 = 2
The last number is
an = a1 + (n-1)d
an = 2 + (50 - 1)*2
an = 2 + 49 * 2
an = 2 + 98
an = 100
Sum of the even numbers
Sum = (a1 + a50)*n/ 2
Sum = (2 + 100)*50/2
sum = 102 * 25
sum = 2550
Sum of the first 50 odd numbers
a1 = 1
n = 50
d = 2
l = ?
Find l
l = a1 + (n - 1)*2
l = 1 + 49*2
l = 99
Sum
Sum = (1 + 99)*50/2
Sum = 2500
The difference and answer is 2550 - 2500 = 50
Answer:
The square root of six hundred and eighty-three √683 = 26.13426869074
A^3c^3m^3
it would be a cubed or a to the third power, c cubed or c to the third power, and m cubed or m to the third power
Answer:
A is the correct answer
Step-by-step explanation:
When x =4 and y =-5, and you want to evaluate equation -3x+2y, you just have to apply it into the equation.
We got the equation as:
= -3x + 2y
= -3*4 + 2*(-5)
= -12 + (-10)
= -12 - 10
= -22
Hope this help you :3
