Answer:
m= 1.1
Step-by-step explanation:
Given the question as 7:( 4/11 m)=56:3.2 this can be written as;
7: 4/11 m = 56 /3.2
7/4/11m = 560/32 ------------------perform cross multiplication
77*32=560*4/11m
224=2240/11 m
224=203.636 m--------------divide both sides by 203.636 to get m
224/203.636 = 203.636m/203.636
1.1 =m
Testing the value of m in the question
7: (4/11 *1.1) = 56:3.2
7:0.4 = 56 :3.2
70/4 = 560/32
17.5 =17.5
All you do is subtract 5.5 oz from 12.25 oz, so the answer is that the blue balloon has 6.75 more oz than the other balloon.
V = 4/3(pi)(r^3)
V = 4/3(pi)(4.2^3)
V = 310 cm^3
Good luck!
Here's the general formula for bacteria growth/decay problems
Af = Ai (e^kt)
where:
Af = Final amount
Ai = Initial amount
k = growth rate constant
<span>t = time
But there's another formula for a doubling problem.
</span>kt = ln(2)
So, Colby (1)
k1A = ln(2) / t
k1A = ln(2) / 2 = 0.34657 per hour.
So, Jaquan (2)
k2A = ln(2) / t
<span>k2A = ln(2) /3 = 0.23105 per hour.
</span>
We need to use the rate of Colby and Jaquan in order to get the final amount in 1 day or 24 hours.
Af1 = 50(e^0.34657(24))
Af1 = 204,800
Af2 = 204,800 = Ai2(e^0.23105(24))
<span>Af2 = 800</span>
Answer:
See below.
Step-by-step explanation:
The expression 
is equivalent to the decimal -0.8 or -80%. It is also equivalent to the fractions 
since these simplify to 4/-5.
