Answer:
Roman can type 1.5 more pages in 90 minutes than 60 minutes.
Step-by-step explanation
In 60 Roman can type 3 pages. Divide those numbers in half to find out how many pages he can type in 30 minutes. Add 30 minutes to 60 minutes and 3 pages to 4.5 to get 90 minutes.
Roman can write = 4.5 - 3 = 1.5 = 1 and a [tex]$\frac{1}{2}[/tex] page more in 90 minutes than in 60 minutes.
We have Roman who can type 3 pages in 60 minutes.
We have to find out how many more pages can Roman type in 90 minutes than in 60 minutes.
If you solve 5 questions of mathematics in 1 hour, then how many questions will you solve in 10 hours.The number of questions you will solve will be = 5 x 10 = 50 questions.
According to the question, we have -
Number of pages typed by Roman in 60 minutes = 3
Therefore -
In 60 minutes → 3 Pages.
In 1 minute → 3/60 Pages.
In 90 minutes → [tex]\frac{3}{60} \times 90[/tex] = 4.5 pages = 4 and a [tex]$\frac{1}{2}[/tex] page.
Therefore, Roman can write = 4.5 - 3 = 1.5 = 1 and a [tex]$\frac{1}{2}[/tex] page more in 90 minutes than in 60 minutes.
Hence, Roman can write 1 and a [tex]$\frac{1}{2}[/tex] page more in 90 minutes than in 60 minutes.

Answer:
X= 4/5
Step-by-step explanation:
3*2-5x-2=0
step 1 : combine/multiply like terms

Write the repeating decimal 4.1363636… as a fraction.
Answer:4¹⁵/110
Step-by-step explanation:
Take x to be the number
X=4.13636363
Since the repeating numbers are 2 you multiply the number by 100
100x =413.636363
When we minus 413.6363 and 4.136363 we will get a decimal
We multiply the value for x by 1000 we get 4136.3636
And when we minus 4136.3636 by the values of 1x and 100x we will still get a decimal
We multiply the value of x by 10000 we will get 41363.6363 when we divide it by the values of 1x we will get a decimal but when we divide it by the value of 100x we will not get a decimal
Then we minus them
10000×-100×=9900x
41363.6363-413.6363=40950
9900x=40950
Divide both sides by 9900
9900x÷9900=40950÷9900
X=4¹⁵/110

What is an quadratic equation?We define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = [tex]ax^{2} +bx+c[/tex], where a, b, and c are numbers and a cannot be 0.
Example of quadratic equation is y = [tex]x^2 + 3x + 1.[/tex]
Given quadratic equation
[tex]-16t^{2} +40t =0[/tex]
⇒ [tex]16t^{2} -40t=0[/tex]
⇒ [tex]8(2t^{2}-5t)=0[/tex]
⇒ [tex]2t^{2}-5t=0[/tex]
⇒ [tex]t(2t-5)=0[/tex]
⇒ [tex]t_{1} =0[/tex] and [tex]t_{2}=\frac{5}{2} =2.5[/tex]
T = [tex]t_{2}-t_{1} =2.5-0 = 2.5[/tex]

Here is a five-sided polygon. Describe or show the strategy you would use to find its area. Mark up and label the diagram to show your reasoning so that it can be followed by others. (It is not necessary to actually calculate the area.)
Answer:
i can explai it to u if u wan to get the answer
Step-by-step explanation:
Divide the polygon into 5 triangles by using each side as a base and joining the vertices of the polygon to a common point (for example, the centre). If the polygon is regular the angle at the vertex of each triangle is 360/5=72 degrees, so you have 5 isosceles triangles of equal area. Find the area of one and multiply by 5 to get the total area.multiply 5 times the lenght of oneside

On understanding Benford's law, only 1 and 4 can be included in the solution set out of all the given values.
What is Benford's Law?Benford's law (also called the first digit law) states that the leading digits in a collection of data sets are probably going to be small.
We need to check if the given values can be included in the solution set satisfying Benford's law.
The first digit of any number has to be whole number. Thus, 0.5, 2.5 and 3.5 cannot be included in this solution set.
Now, for 1, 4 and 5, we have to observe the graph. As visible, no value of 5 falls inside the shaded region. Thus, only 1 and 4 can be included in the solution set.

for a car driving at a constant rate of 60 miles per hour, the table represents distance from a historical mile marker on the highway as a function of dribing time. which equation could be used to determine the driving time(s) when the car is 150 miles from the historical mile marker?
Answer:
Option (4)
Step-by-step explanation:
If we plot the points given in the table attached,
We can get the graph of an absolute function with the line of symmetry as,
x = 4
Let the equation of the parent function (of the absolute function) is,
y = m|x| [Line of symmetry x = 0]
here m = speed of the car = 60 mph
so the equation will be in the form of y = 60|x|
Since, line of symmetry is x = 4, parent function has been translated by 4 units to the right.
So the equation of the transformed function will be,
y = 60|x - 4|
If the car is at 150 miles, equation to determine the driving time will be,
150 = 60|x - 4|
Option (4) will be the answer.

What is the range median and mode for 8 7 12 7 11 10 7 12
Answer:
Range = 5, Median = 9, Mode = 7
Step-by-step explanation:
First, we put them in order from least to greatest.
So its 7, 7, 7, 8, 10, 11, 12, 12
The range is the largest number minus the smallest number, so 12-7=5. The range is 5.
The median is the number in the middle, so we cross off numbers from both sides. That leaves us with 8 and 10. The number between them is 9, so the median is 9. (the actual process to find the median if there's 2 numbers in the middle is by adding them together and dividing them by 2)
The mode is just which number appears the most often. So 7 is the mode.
