Answer:
So the perimeter of the larger rectangle = 160
Step-by-step explanation:
We are given the scale factor of the two rectangles. We are given the perimeter of the smaller rectangle = 120.
Since the two rectangles are scaled, this means they have a common ratio. In other words:
[tex] \frac{perimeter \: of \: larger \: rectangle}{perimeter \: of \: smaller \: rectangle} = \frac{4}{3} [/tex]
As given in the question.
Now we know the smaller rectangle has a perimeter of 120.
Let's take the perimeter of the larger rectangles as x.
[tex] \frac{x}{120} = \frac{4}{3} \\ \\ multiplying \: both \: sides \: by \: 120 \\ x = \frac{4}{3} (120) \\ x = 160[/tex]
So the perimeter of the larger rectangle = 160
Two trains leave stations 520 miles apart at the same time and travel toward each other. One train travels at 110 miles
per hour while the other travels at 90 miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.
Answer:
They wont meet
Step-by-step explanation:
The one going 110 will pass before the other one can reach it.
Please mark me the brainliest, 5 stars, and a thanks! Have a great day!
It will take 2.6 hours (or 2 hours and 36 minutes) long for the two trains to meet when Two trains leave stations 520 miles apart at the same time and travel toward each other.
To find the time it will take for the two trains to meet, we can use the concept of relative speed.
The two trains are traveling towards each other, so their speeds add up. The combined speed of the two trains is:
110 mph + 90 mph = 200 mph
To determine the time it will take for the trains to meet, we can divide the total distance they need to cover (520 miles) by their combined speed (200 mph):
Time = Distance / Speed
Time = 520 miles / 200 mph
Time = 2.6 hours
Therefore, it will take 2.6 hours (or 2 hours and 36 minutes) for the two trains to meet.

The average value of a function f on [a, b]
always lies between f(a) and f(b). Justify your answer.
Answer:
False
Step-by-step explanation:
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi]. sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
The average value of a function f on [a, b] always lies between f(a) and f(b) is false.
What is a function?A relation is a function if it has only One y-value for each x-value.
The average value of a function over an interval [a,b] is the total area over the length of the interval
A parabola is a good example of proving this false, but more specifically is the graph of sin x on the interval [0, pi].
sin 0 = sin pi = 0, but the average value of sin x on this interval is greater than 0.
So the average value of a function f on [a, b] always lies between f(a) and f(b) is false.
Hence, the average value of a function f on [a, b] always lies between f(a) and f(b) is false.

Find the sum of the arithmetic series given a1
12, d = 4, and n = 30.
A. 8434
B. 4200
C.4216
D. 2100
Answer:
D
Step-by-step explanation:
The sum to n terms of an arithmetic series is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12, d = 4 and n = 30 , then
[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × 12) + (29 × 4) ]
= 15(24 + 116)
= 15 × 140
= 2100 → D
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100, therefore the correct answer is D.
What is the Sum of arithmetic series?The sum of n terms of an arithmetic series can be easily found using a simple formula which says that, if we have an arithmetic series whose first term is a and the common difference is d, then the formula of the sum of n terms of the arithmetic series is as follows
Sn = n/2 [2a₁ + (n-1)d].
as given in the problem
a₁ =12, d = 4, and n = 30
Sn = 30/2 [2×12 + (30-1)×4]
= 2100
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100.

Answer:
4
Step-by-step explanation:
We are asked to find a slope whilst given a graph.
To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.
So based on what I see, I can see (1, 1) and (2, 5).
The rise over run is as followed :
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
2 and 1 meaning the first and second number within the coordinate, so substitute :
[tex]\frac{5 - 1}{2 - 1}[/tex]
[tex]\frac{4}{1}[/tex]
Divide :
[tex]4[/tex]
4 is our slope.

The cost of every college is expected to increase 3.5%
next year.
The cost to attend Faber College is currently $24000.
If the percentage increase stays constant, what will the
cost be in TWO years?
Answer:
25,709.4
Step-by-step explanation:
First you would multiply 3.5 x 24,000, and then divide by 100, to get 840, and then add that to the original amount to get 24,840, and that is the cost for one year. And then you would multiply 24,840 by 3.5 and then divide by 100 to get 869.4. Finally just add that to 24,840 to get 25,709.4, and that is the cost for 2 years. I hope this helps :)
The cost of college in two years is $25709.4.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Cost of Faber college = $24000
Rate of increase = 3.5%
The cost of college after one year.
= 103.5% of 24,000
= 103.5/100 x 24000
= $24,840
The cost of their college after two years.
= 103.5% of 24,000
= 103.5/100 x 24,840
= $25709.4
Thus,
The cost of college in two years is $25709.4.

Tom has three times as many action figures as Jerry. If Tom has 27 action figures, how many does Jerry have? Write an equation that represents the scenario. Then solve.
Answer:
Jerry has 9 action figures.
Step-by-step explanation:
Since Tom has three times as many action figures as Jerry, Tom has 3x action figures, where x is the number of action figures that Jerry has.
Since Tom has 27 action figures, we can say that 3x=27.

Machine A and machine B both make car parts.
Machine A makes 7 parts every 10 minutes.
Machine B makes 16 parts every 15 minutes.
On Monday
machine A makes parts for 12 hours
machine B makes parts for 10 hours
Work out the total number of parts made by the two machines on Monday.
Answer: 1144
Step-by-step explanation:
Given: Machine A makes 7 parts every 10 minutes.
i.e. it makes [tex]\dfrac{7}{10}[/tex] parts in 1 minute.
Machine B makes 16 parts every 15 minutes.
i.e. it makes [tex]\dfrac{16}{15}[/tex] parts in 1 minute.
On Monday,
machine A makes parts for 12 hours(720 minutes). [1 hour = 60 minutes, 12 hours = 12 x 6 = 720 minutes]
i.e. Total parts made = [tex]\dfrac{7}{10}\times720[/tex]
i.e. Total parts made = 504
machine B makes parts for 10 hours(=60x 10=600 minutes)
i.e. Total parts made = [tex]\dfrac{16}{15}\times600[/tex]
i.e. Total parts made = 640
Total parts made by both machines = 504+640 =1144
Hence, the total number of parts made by the two machines on Monday=1144.
