If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your answer should be written as a decimal rounded to the nearest tenth if necessary.
Answers
The number of pages the student can read in a minute is an illustration of rates.
The time left to complete the whole book is 90 minutes
From the complete question, the student's rate is:
[tex]\mathbf{Rate = 50\ pages/hr}[/tex]
The number of pages is:
[tex]\mathbf{Total = 100\ pages}[/tex]
First, we calculate the time to read the whole book
[tex]\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}[/tex]
[tex]\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}[/tex]
[tex]\mathbf{Total\ Time = 2\ hours}[/tex]
The number of the student has read is:
[tex]\mathbf{Pages = 25}[/tex]
Next, we calculate the time spent on the 25 pages
[tex]\mathbf{Time\ Spent = \frac{Pages}{Rate}}[/tex]
[tex]\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}[/tex]
[tex]\mathbf{Time\ Spent = 0.5\ hr}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Spent = 30\ minutes}[/tex]
So, the time left is:
[tex]\mathbf{Time\ Left = Total\ Time - Time\ Spent}[/tex]
This gives
[tex]\mathbf{Time\ Left = 2\ hours- 30\ minutes}[/tex]
[tex]\mathbf{Time\ Left = 1\ hour, 30\ minutes}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Left = 90\ minutes}[/tex]
Hence, the time left is 90 minutes

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 3 to 2 if there were 4440 total votes how many yes votes were there
Answers
Answer:
Y / N = 3 / 2
N + Y = 4440
Since Y = 3/2 N
3/2 N + N = 4440
5/2 N = 4440
N = 8880 / 5 = 1776
Y = 1776 * 3 / 2 = 2664
1776 + 2664 = 4440

a What is the mass of wheat and oats in one portion of Lee's muesli?
b What is the mass of nuts in one serving of Lee's muesli?
Answers
Answer:
Total weigh = 75g
a) so the mass of wheat and oats one protion = 75*(71/100) g = 53.25g
b) the mass of nuts in one serving = 75*(2.5/100) g = 1.875g

work out the gradient of the line y=5x-3
Answers
Answer:
The answer is 5
Step-by-step explanation:
The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer. The slope is 5.
The slope is the ratio of rise to run of a line. The gradient of the line y=5x-3 is 5
How to determine the gradient of a line?The gradient of a line is also known as the slope and it is the ratio of rise to run of a line
The standard equation of a line in slope-intercept form is expressed as y = mx +b
m is the slope or gradient
Given the equation of a line y = 5x - 3
Compare
mx = 5x
m = 5
Hence the gradient of the line y=5x-3 is 5

Answer:
to simplify the square root of 75, first I recognize that the perfect square 25 goes into it. So 75 = 25 x 3. Therefore the square root of 75 equals the square root of 25 times the square root of 3. And that means just 5 times the square root of 3.
Step-by-step explanation:
The square root of √75 is 5√3.
What is Radical?The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.
A radical notation is an expression that incorporates a root, such as the square or cube root.
Given:
We have to find the square root of 75.
So, we have to factories 75 as
= 25 x 3
and, the square root of 25 is 5.
Then, √75 = √( 5 x 5 x 3)
= 5√3.
