Answer:
6 hours
Step-by-step explanation:
For Bob
12 hours = 1 fence
1 hour = 1/12 fence
Together Bob and Jen
4 hours = 1 fence
1 hour = 1/4 fence
Now, for Jen:
1 hour = 1/4 - 1/12= 3/12 - 1/12 = 2/12=1/6
Find the amount of time Jen will need:
1/6 fence = 1 hour
1 fence = 6 hour
Answer:
x=5
Step-by-step explanation:
The sides have to be equal length
3x+4 = 5x-6
Subtract 3x from each side
3x+4-3x = 5x-6-3x
4 = 2x-6
Add 6 to each side
4+6 = 2x-6+6
10 = 2x
Divide by 2
10/2 =2x/2
5 =x

10 is the least of the numbers, it is the lowest
10<14,16,20,29
Answer:
D
Step-by-step explanation:
By definition for a right triangle with sides a, b, c, where c is the hypotenuse,
the following must be true:
a² + b² = c²
By using this formula on all the choices, we find that only D satisfies this formula
i.e.
for
a = √35 --------> a² = 35
b = √14 --------->b² = 14
c = 7 ------> c² = 49
a² + b² = 35 + 14 = 49 which is equal to the value of c² above
