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

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.

The population of a city can be modeled by the expression p(1.06)^t where t represents the number of years since 1990 and p represents the population in 1990. which statement is correct?
A. the year growth rate of the population is 0.06%
B. the yearly growth rate of the population is 0.6%
C. the yearly growth rate of the population is 1.06%
D. the yearly growth rate of the population is 6%
please respond if you actually know the answer :)
Answer:
D
Step-by-step explanation:
.06 =6%
The expression p(1.06)^t represents D. the yearly growth rate of the population is 6%
What is the population growth rate?The country's yearly average rate of change in population size over a certain time period. It expresses the proportion, growth in population size, and the total population for that year.
Given, The population of a city can be modeled by the expression
[tex]p(1.06)^t[/tex] where t represents the number of years.
This describes the yearly growth rate of the population is 6%.
If in the previous year the population was 100 this year it'll be 106 and next year it'll be 106% of 106 which is 112.36.

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.

Renee is creating a diagram to prove that a certain triangle is a right triangle. In her diagram, she uses three white quadrilaterals that are squares. Which diagram could be the one that Renee is creating
Answer:
Option D
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:
c² = a² + b²
From the options, option d is the correct option.
For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:
c² = a² + x²
x² = c² - a²
x = √(c² - a²)
Therefore the other leg would be √(c² - a²)

what is the smallest integer greater than the square root of 85?
Answer:
the answer is 9.2
Step-by-step explanation:
The radical value √(85) lies between 81 and 100. So, the smallest integer greater than the square root of 85 is 10.
Radical:Important information:
The given radical value is [tex]\sqrt{85}[/tex].The perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
It is clear that,[tex]81<85<100[/tex]
Taking square root on each side, we get
[tex]\sqrt{81}<\sqrt{85}<\sqrt{100}[/tex]
[tex]9<\sqrt{85}<10[/tex]
The value [tex]\sqrt{85}[/tex] lies between 9 and 10.
Therefore, the smallest integer greater than the radical value square root of 85 is 10.
