Wouldn't it be B ??? Hope this is right:) can you take a look at mine??
Depends. All multiples of 400, you could have many different options. For example, 400 buses 1 kid on ea. 40 buses 10 kids on ea.
400x1=400
40x10=400
Just if the two numbers multiple to 400 it can be an answer
A) The correct way to write 1/4 as a precent is 25%.
because....
1÷4= .25. and .25×100= 25%
b) The reporter most likely forgot to multiply by 100. The reporter instead just found what 1/4 was as a decimal, not a precent.
Answer:
A. 
B. 
Step-by-step explanation:
Given that:
An investment of Amount = $8000
earns at an annual rate of interest = 7% = 0.07 compounded continuously
The objective is to :
A) Find the instantaneous rate of change of the amount in the account after 2 year(s).
we all know that:
where;
The instantaneous rate of change = 
At t = 2 years; the instantaneous rate of change is:
(B) Find the instantaneous rate of change of the amount in the account at the time the amount is equal to $12,000.
Here the amount = 12000
㏑(1.5) = 0.07 t
0.405465 = 0.07 t
t = 0.405465 /0.07
t = 5.79
At t = 5.79
Answer: 3cm
Step-by-step explanation:
The volume of a cylinder is calculated by using the formula:
Volume = πr²h
where,
π = 3.14
r = unknown
h = height = 8cm
Volume = πr²h
3.14 × r² × 8 = 226
25.12r² = 226
Divide both side by 25.12
r² = 226/25.12
r² = 8.9968
r² = 9 approximately
r = ✓9
r = 3
The radius is 3cm
