Answer:
C
Step-by-step explanation:
Given y ∝ then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = - 2 when x = 14 , then
- 2 = ( multiply both sides by 14 )
- 28 = k
y = - ← equation of variation
Answer:
R = 2 % per annum.
Step-by-step explanation:
SI = (P*T*R) /100

Answer:
5 1/7 hours
Step-by-step explanation:
We're looking to calculate TIME. In this situation the proper expression is:
6 letters
time = -----------------------------------------------------------
2 letters / 4 hours + 2 letters / 6 hours
We can divide numerator and denominator both by "2 letters" to simplify the problem:
3 3 hours 3 hours
time = ----------------- hours, or ------------------ = -----------------
1/4 + 1/3 3/12 + 4/12 7/12
Invert the divisor 7/12, and then multiply: (3 hours) (12/7) = 36/7 hours, or
5 1/7 hours
It will take these two guys 5 1/7 hours, working together, to type these 6 letters.
Answer: He should buy 11 feet of green thread.
Explanation: if every bracelet uses 22 inches of each color of thread and Neil wants to make 6 bracelets we can multiple 22 * 6= 132inches
There is 12 inches in one feet so we divide
132/12= 11 feet
