Answer:
4 hours and 33 minutes
Step-by-step explanation:
Before I answer, I was confused if recess and lunch are 35 minutes in total or 35 minutes each. My answer is if they are 35 minutes combined. If that's wrong, you can just add 35 minutes to my answer.
5*45 = 225
225+35 = 260 minutes or 4 hours and 33 minutes
I think it A... But if it not sorry I didn’t help... hope this is the answer I am sure it is...
This exponential growth/decay (in this case decay because r<1) of the form:
f=ir^t, f=final value, i=initial value, r=common ratio or "rate", t=time.
Since the population decreases by 4.5% each year the common ratio is:
r=(100-4.5)/100=0.955 so we can say
P(t)=8500(0.955^t)
....
7000=8500(0.955^t)
14/17=(955/1000)^t taking the natural log of both sides
ln(14/17)=t ln(955/1000)
t=ln(14/17)/ln(955/1000)
t≈4.22 years (to nearest hundredth of a year)
Since t is the years since 2010, the population will fall to 7000 in the year (2010+4.22=2014.22, more than four years will have elapsed) 2015.
Answer:
-1 <x < 7
(-1,7)
Step-by-step explanation:
open circle on the left means the number is greater than
-1 <x
Open circle on the right means the number is less than
x < 7
Since both statements are true. we combine them
-1 <x < 7
open circles means parentheses, closed circles mean brackets
The second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
<h3>
Which statement is always true?</h3>
Remember that for integer numbers, we have the following properties:
- Commutative property: A + B = B + A
- Associative property: (A + B) + C = A + (B + C)
Now, in this case we know that a and b are integer numbers, first we can see that the second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
The other 3 statements are false. You can see it by evaluating a = 0 and b = 1.
