Answer:
Volume is 9.428 cu.cm
It is asked for nearest tenth so it would be 10 cu.cm
To determine the number of years to reach a certain number of population, we need an equation which would relate population and the number of years. For this problem, we use the given equation:
<span>P=1,000,000(1.035)^x
We substitute the population desired to be reached to the equation and evaluate the value of x.
</span>P=1,000,000(1.035)^x
1400000=1,000,000(1.035)^x
7/5 = 1.035^x
ln 7/5 = ln 1.035^x
x = ln 7/5 / ln 1.035
x = 9.78
Therefore, the number of years needed to reach a population of 1400000 with a starting population of 1000000 would be approximately 10 years.
Find volume of each bill and each room
v=lwh
vbill=6.14*2.61*0.0043=0.06890922 in^3
must convert room dimientions to inches
25*12=300in
23*12=276in
15*12=180in
Vroom=300*276*180=14904000in^3
now 1 billion bills
move decimal place over 9 places to right
1 million bills takes about 68909220 in^2
how many rooms to fit them all?
vbillionbills/v1room=number of rooms needed=
68909220/14904000=4.623
round to 1 deicmal
4.6 rooms needed (actually, it would be 5 since you can't use the 0.4 room left over very efficiently)
answer is 4.6 rooms
Answer:
14(4n - 5)
Step-by-step explanation:
The GCF of 56 and 70 is 14
56/14 = 4
70/14 = 5
Place the GCF outside the parenthesis
14(
and keep the n on 56 and put it on 14, = 14n,
14(4n
then keep the subtraction sign and 5 and put it in the parenthesis
14(4n - 5)
i hope that maked sense and helped you! (and could i have brainliest if possible it would really help me!)
Answer:
(3 (pm) sqrt(7))/2
Step-by-step explanation:
First step: Identify a,b, and c
a=2
b=-6
c=1
Second step: Find b^2-4ac (this is called the discriminant-I will call this D)
(-6)^2-4(2)(1)=36-8=28
Third step: Find the square root of the discriminant aka sqrt(D)
sqrt(28)
Let's see if we can simplify sqrt(28)
Here is there a factor of 28 that is a perfect square? How about 4? Yep!
sqrt(28)=sqrt(4)sqrt(7)=2sqrt(7).
Fourth Step: What is -b? If b=-6 then -b=6.
Fifth step: What is 2a? 2(2)=4
So the formula is
x=(-b (pm) sqrt(D))/(2a)
or
x=(step4 (pm) step 3)/(step 5)
x=(6 (pm) 2sqrt(7))/4
Simplify
x=(3 (pm) sqrt(7))/2
*pm means plus or minus
*sqrt( ) means square root of the number that follows in the ( )
