The period of oscillation of a pendulum is
Where L is the length of the pendulum and
the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:

Answer:
If he missed five questions he can get a zero
Step-by-step explanation:
Equation: 9÷ 6/7
First turn that whole number into a fraction: 9/1.
9/1 ÷ 6/7
Put into effect the rules of dividing fractions which is keep the first fraction the same, turn the division sign into a multiplication sign, and flip the second fraction to its reciprocal.
9/1× 7/6
Multiply (multiply the numerators then the denominators.)
63/6
Simplify
The answer is 1.5 or 1 1/2
1) No. A closet is an area. The 1st closet area = 3 x 5 = 15 & the area of the 2nd closet is 6 x 10 =60 . Then it's 4 times larger
2) find both perimeters: 1st = 30 feet & 2nd = 120 ft
3) find both area 1st = 15 ft² & 2nd = 60 ft²
4) Since the 2nd carpet is 4 times larger than the old, then the cost of the new carpet will be 4* 42= $168
