4n+2 (n+1) >n+52 Please solve this inequality fast.
Answer:
n>10.2 or n>51/5
Step-by-step explanation:
4n+2(n+1)>n+52 distribute 2 to everything in the parentheses
4n+2n+1>n+52 combine like terms
6n+1>n+52 subtract 1 from both sides
6n>n+51 subtract n from both sides
5n>51 divide both sides by 5
n>10.2

Distance between Train 1 and Train 2 =95 miles.
Average speed of Train 1 = 45 mph.
Average speed of Train 2 60 mph.
If both trains leave at the same time and travel toward each other but on parallel tracks, in how much time will their
engines be opposite each other? (Hint: When the engines are opposite each other, together the trains will have traveled
95 miles. Their relative speed of travel is the sum of their respective speeds, or 105 mph.)
Travel time = Mhours
Step-by-step explanation:
Distance between Train 1 and Train 2=95 miles
Avg speed Train 1 = 45mph, avg speed Train 2=60mph
If both trains leave at the same time and travel toward each other but on parallel tracks, in how much time will their engines be opposite each other?
:
Let t = travel time (in hrs) until they are opposite each other
:
Like the hint said, when this happens the total distance traveled by both trains will be 95 mi.
:
write a distance equation from this fact: Dist = speed * time
;
Train 1 dist + train 2 dist = 95 mi
45t + 60t = 95
:
105t = 95
t = 95%2F105
t = .90476 hrs
or
.90476 * 60 = 54.3 min
:
:
Check solution by finding the total of the distances the two train travel
45(.90476) + 60(.90476) =
40.7 + 54.3 = 95 mi

Ratio of 200m and 1km.
Answer:
the ratio of this one is 0.2\1
Answer:
To calculate the ratio, we should have both quantities in same units, so we can convert the kilometer into meters, knowing that 1 kilometerr are 1000m.
1 * 1000 = 1000m
We know we need to calculate the ratio 200:1000.
We can know divide both quantities by 200 and get...
200/200:1000/200 = 1:5
And now,, we know this ratio is 1:5..

Matthew purchased a desk that was on sale for 45% off the orginal price of $480.If the sales tax was 8% (of the sale price), how much did mattew spend on the desk
Answer:
285.12
Step-by-step explanation:
discount amount = 45/100 x 480= 45x48/10
=216.0
price after discount= 480-216=264
sales tax= 8/100 x 264=21.12
total money spent = 264+21.12=285.12
45% of 480
= 45/100 x 480
= 0.45x480
=216
=480-216
=264
8% of 264
= 8/100 x 264
= 0.08 x 264
= 21.12
= 264 + 21.12
=285.12
Therefore, he paid $285 and 12 cents

You deposit $300 in a savings account that pays 6% interest compounded semiannually. How much will you have at the middle of the first year? How much at the end of one year?
Answer:
The total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 0.5 years is $ 309.00. The total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 1 year is $ 318.27.Step-by-step explanation:
a) How much will you have at the middle of the first year?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
where
Principle = PAnnual rate = rCompound = nTime = (t in years) A = Total amountGiven:
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 0.5 years
To determine:
Total amount = A = ?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
substituting the values
[tex]A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}[/tex]
[tex]A=300\cdot \frac{2.06}{2}[/tex]
[tex]A=\frac{618}{2}[/tex]
[tex]A=309[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 0.5 years is $ 309.00.
Part b) How much at the end of one year?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
where
Principle = PAnnual rate = rCompound = nTime = (t in years) A = Total amountGiven:
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 1 years
To determine:
Total amount = A = ?
so using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
so substituting the values
[tex]A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}[/tex]
[tex]A=300\cdot \frac{2.06^2}{2^2}[/tex]
[tex]A=318.27[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 1 year is $ 318.27.

The lengths of a professor's classes has a continuous uniform distribution between 60.0 min and 90.0 minutes. If one such class is randomly selected, find the probability that the class length is less than 76 min.
Answer:
0.533
Step-by-step explanation:
Given that :
Class length has a Continuous uniform distribution between 60 - 90 min
Lower limit (L1) = 60
Upper limit (L2) = 90
Probability that class length is less than 76 min
P(x < 76):
(x - L1) / (L2 - L1)
(76 - 60) / (90 - 60)
16 / 30
= 0.533
P(x < 76) = 0.533

The values shows 13/30 < 9/20.
What is fraction?Fractions are the components of a collection or whole. Two parts make up a fraction. The numerator is the number at the top of the line. It indicates the number of equal portions taken from the collection or whole. The term "denominator" refers to the number below the line. It indicates the total number of identical parts that make up a collection or the total number of parts that make up the whole.
The number of parts we take is a fraction when the whole is divided into equal parts.
Given 13/30 and 9/20
to make the common denominator,
multiply by 20 in numerator and denominator of 13/30
(13 x 20)/(20 x 30) = 260/600
multiply by 30 in numerator and denominator of 9/20
(9 x 30)/(20 x 30) = 270/600
the terms with same denominator are
260/600 and 270/600
as we can see that 270/600 > 260/600
so 13/30 < 9/20.
Hence 13/30 is less than 9/20.
