Answer: A=100(12)t5.27
Step-by-step explanation:
Assume / and ^ got lost from eqns.
A(t) = initial × (1/2)^(t/halflife)
So initial = 100, halflife = 5.27,
A=100(12)t5.27 means A=100(1/2)^(t/5.27)
so that A is 50 when t is 5.27
1/3 divided by 4
1/3 divided by 4/1
1/3*1/4 = 1/12
1/12 quarts are in each cup
Answer:
r = 28.28
Step-by-step explanation:
you already gave the equation: sin45°= 20/r
you wanna start by multiplying both sides by r. You do this so that your variable can be in the numerator and it will be easier to solve the equation:
r (sin45°) = 20
Now you divide both sides by sin45°, this will give you your final answer. For this, you have to put it in a calculator:
r = 28.28
P.S, good job on already knowing your equation... when i was learning this it took me a while to get eh hang of it :)
(4/5)/(2/3)=4/5*3/2=12/10=1 1/5
two fractions dividing is the same as two fractions multiplying with the second fraction flipped around
1 1/5 yards per second
