Answer:
52 pages per 1 hour
Step-by-step explanation:
If Penny reads 13 pages in 1/4 of an hour you need to multiply 13 by 4 to see how many pages she will read in 1 hour.
The unit rate:
52 pages per hour.
0.02 hours per page.
What is division?One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.
To find the unit rate of pages per hour, we need to convert 1/4 hour to hours first.
1/4 hour = 0.25 hour
Then, we can use the formula:
Unit rate = Pages ÷ Time
Unit rate = 13 pages ÷ 0.25 hour
Unit rate = 52 pages per hour
To find the unit rate of hours per page, we can use the reciprocal of the previous unit rate:
Unit rate = Time ÷ Pages
Unit rate = 0.25 hour ÷ 13 pages
Unit rate = 0.0192 hours per page
Rounded to the nearest hundredth, the unit rate is 0.02 hours per page.

75% of what number is 120?
Question 1 options:
1.6
160
10,800
Answer:
160
Step-by-step explanation:
First, lets assign a varible x. Let x be the number where 75% of x is 120. Next, we can convert the words of the problem into an equation. Now we have, 75% * x = 120 = 0.75x = 120. By multiplying both sides by 100, we get, 75x = 12000. So, x = 160.

Applying the negative exponent rule of power, the expressions that are equivalent to the given expression, 1/81, are: B, D, and F.
What is the Negative Exponent Rule of Power?The negative exponent rule states that: [tex]a^{-n} = \frac{1}{a^n}[/tex].
Thus, given the expression, 1/81, it can be rewritten or simplified as follows:
1/81 = [tex]81^{-1} = 9^{-2}[/tex] = [tex]\frac{9^8}{9^{10}}[/tex] = [tex]9^5 \times 9^{-7}[/tex]
The expressions that will be equivalent to 1/81 can be expressed, based on the negative exponent rule of power, as:
[tex]9^{-2}, \frac{9^8}{9^{10}} , 9^5 \times 9^{-7}[/tex] (option B, D, and F).

These are all factors of coastal erosion. (5 Points) Hurricanes Sinkholes Human Impact Glaciers
Answer:
Hurricanes, Sinkholes, Humans Impact, and Glaciers are contributory agents to the issues of coastal erosion.
Explanation
1) Hurricanes:
Sea levels can be rapidly elevated during a storm surge caused by hurricanes and extratropical storms. These spike in sea levels are directly related to severe erosion of shorelines which is estimated to cost about 3-5 billion US dollars annually.
2) Sinkholes:
in 2013, about 328 feet of the beach collapsed in Candelaria, Zambales over a weekend creating an unsafe environment for residents and tourists. Their scientists suspected that it was due to a sinkhole. The collapse had deepened the shoreline by at least 1 meter.
3) Human Impact:
Sand mining from riverbeds and beaches, erection and construction of structures in coastal areas (like seawalls, jetties, breakwaters, etc), land reclamation along coastal fronts are all causes of coastal erosion.
In 2018, India reported massive erosion to its coastline. At that time, she had lost a whopping 33% of her shoreline over a space of 26 years. This is an average of 1.3% annually. Much of this loss was attributed to the increasing number of construction activities in such areas, damming of rivers (which prevented the rivers from carrying sediments to its coast which creates a balance), sand mining, and destruction of mangroves, etc.
4) Glaciers:
A Glacier is a moving body or river of ice that moves relatively slowly. It is formed by the gradual accumulation of compacted snow on mountains or near the poles. Glaciers have been known to move as fast as 30 meters per day. They can also be as slow as 0.5 meters per year. On average, you probably will record 25 centimeters of daily movement.
Combined with its gradual motion, the weight of a glacier could dramatically transform the terrain over a period spanning hundreds or even thousands of years. The weight of a glacier is very crushing. It is estimated at about 2 thousand tonnes.
As this huge weathering machine moves over land surfaces, expanding and contracting with weather fluctuations, the rocks underneath are disintegrated systematically into soil and shipped far from their points of origin.
The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
Moving glaciers rip out of basins and create mountain valleys with sloping cliffs. Interesting historical examples of what Glaciers can do can be found in Scandinavia where it created fjords and deep inlets along its coast. It is also interesting to note that the shape of Cape Cod which looks like a fishhook was carved by the snout of a glacier.

line 3x - 5y = 1
A. (1, 2)
B. (2,1)
C. (3/5,1)
D. (2,3)
Answer:
B. (2,1)
Step-by-step explanation:
Substitute the first value from the parentheses for x, and the second value for y in the equation.
Calculate.
If the answer is true, the point is a solution on the line.
3(2) -5(1) = 1
6 –5 = 1
1 = 1. True. point B is a solution on the line.
D* for example:
3(2) -5(3) = 1
6 - 15 = 1
–9 = 1 False. This is not a solution on the line.

mrs jones mowed 2/5 of her lawn. her son mowed 1/4 of it. how much of the lawn. How much of the lawn still needs to be mowed
Answer:
7/20 of the lawn still needs to be mowed.
The son mowed most of the lawn 7/20 of the lawn still needs to be mowed.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Mrs. jones mowed 2/5 of her lawn and her son mowed 1/4 of it.
Now, Size of the lawn mowed by Miss Jones = 1/4
And, Size of the lawn mowed by her son = 2/5
To know who mowed the most lawn, find the LCM of the denominators.
The LCM of 4 and 5 = 20
Make the denominators of both fractions to be 20
Hence, Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20
And, Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20
Since, 8/20 > 5/20, Miss Jones son mowed more part of the lawn than Miss Jones.
Hence, The part of the lawn still needs to be mowed is,
⇒ 1 - 1/4 - 2/5
⇒ 7/20

Answer:
y = -5x + 8
Step-by-step explanation:
Slope-intercept form = ('y = x + b')
x being slope; b being the y-intercept.
Slope = rise/run (or y/x)
Take for example the point on the y-intercept, find the next intercepting point.
(0, 8); (1, 3)
In these points, y (rise/fall) decreases by 5. x increases by 1. Using rise/run (or y/x), we conclude that the slope is -5\1.

B. No since the function is undefined at x=1
C. Yes since the function is defined at x=1
D. Yes since the value of the function at x=1 is 4

Step-by-step explanation:
Given:
[tex]\to f(x)=2x^2-3x+1\\\\when \ x=1\\\\\to f(1)= 2(1)^2-3(1)+1\\\\\to f(1)= 2(1)-3+1\\\\\to f(1)= 2-3+1\\\\\to f(1)=-1+1\\\\\to f(1)=0[/tex]
