Answer:1.56
Step-by-step explanation:
For constant of proportionality of k,
y=(1/k)*x
If y =9,
9=7/k
K=7/9=0.78
y=0.78x
y=0.78*2=1.56
When x
3 giant Sandwiches,
8 friends,
Have to be shared equally,
Each friend gets =
If we solve, we'll end with 0.375 Which is between 0 and 1.
So,
It will lie in between 0 and 1.

Answer:
B
Step-by-step explanation:
You just need to find the volumes of both container and soap and divide them. So;
Volume of Soap = 15cm * 8cm * 6cm = 720 cm^3
Volume of Container = 165cm * 40cm * 96cm = 633600 cm^3
Dividing them gives = 633600 cm^3 / 720 cm^3 = 880
Answer is B.
Half life means only half of matter is left, which means half is decayed/radiated.
Formula for half life is
t/2 = [(elapsed time)*(log2)]/[log(beginning amount/ending amount)]
1. t/2 = [(10)*(log2)]/[log(100/76.1)] = 25.378 minutes.
t/2 = [10 * 0.301]/[log 1.314] = [3.01]/[0.1186] = 25.378
2. 53.12 = [(T)*(log2)]/[log(15/4)], on solving we get, T = 101.29 days
53.12 = [T * 0.301]/[log 3.75] = [0.301 * T]/[0.574],
T = [53.12 * 0.574]/[0.301] = [30.49]/[0.301] = 101.29<span />
