Question
How much time did a person spend at the library over a month for them to spend 40 hours reading a book?
Round your final answer to the nearest whole number.
Answer:
The correct answer will be "1.60 hours".
Step-by-step explanation:
Within this test case, let's suppose that the bookstore had been closed on Sundays every other day while there were a total of 5 Sundays throughout the month of thirty days, thus effectively.
Months = 30
Number of sundays = 5
⇒ [tex]Effective \ working \ days = Months - Number \ of \ Sundays[/tex]
⇒ [tex]=30-5[/tex]
⇒ [tex]=25[/tex]
As we know, the total spend time will be 40 hours, then
⇒ [tex]Time \ spend \ each \ day = \frac{Total \ time \ spens}{Working \ days}[/tex]
On putting the estimated values, we get
⇒ [tex]=\frac{40}{30}[/tex]
⇒ [tex]=1.60 \ hours[/tex]

Leia cuts congruent triangular patches with an area of 15 square centimeters from a rectangular piece of fabric that is 15 centimeters long and 9 centimeters wide. How many of the patches can Leia cut from 31 pieces of the fabric?
Answer:
279 patches can be made.
Step-by-step explanation:
Evaluate the total area of the rectangular piece of fabric, therefore:
Area= l*w = 15*9=135
There are 31 pieces, so the total area is 135* 31 =4,185 square centimeters.
Evaluate the number of triangles that can be made dividing the total area by the area of 1 triangular piece, therefore:
n= 4,185/15=279
So the answer is 279 triangles can be made.
On a coordinate plane, a line goes through (0, negative 3) and (3, negative 2). A point is at (negative 4, 2).
Find the equation of the line parallel to line h that passes through (–4, 2).
y = one-third x + StartFraction 10 Over 3 Endfraction
y = negative one-third x + two-thirds
y = 3x + 14
y = –3x – 10
Answer:
Correct option: first one -> y = (1/3)x + (10/3)
Step-by-step explanation:
The linear function that represents a line is:
y = ax + b
Where a is the slope and b is the y-intercept.
First we need to find the slope of the line that goes through (0, -3) and (3, -2).
Using both points, we can find the equation of the line:
x = 0 -> y = -3
-3 = a*0 + b
b = -3
x = 3 -> y = -2
-2 = 3a - 3
3a = 1
a = 1/3
The parallel line needs to have the same slope as the line, so we can model the parallel line with the following equation:
y = (1/3)x + b
The parallel line goes through the point (-4, 2), so we have:
x = -4 -> y = 2
2 = (1/3)*(-4) + b
b = 2 + (4/3)
b = 10/3
So the equation of the parallel line is:
y = (1/3)x + (10/3)
Correct option: first one
Answer:
A.) y = one-third x + StartFraction 10 Over 3 Endfraction

(x - (—— • x)) - — = 0
10 2
Simplify 1/2
1 9
(x - (— • x)) - — = 0
2 2
x = 9
Answer:
x = 9
Step-by-step explanation:
Firstly, you have to balance the equation.
Start by subtracting 0.5 from both sides. Remember, when solving algebraic equations such as this one, you use reverse PEMDAS, or SADMEP.
Now, you have 0.5x = 4.5
Now, for the next step: division. Divide both sides by 0.5, or in other words, multiply by 2.
x = 9

A triangle was dilated by a scale factor of 6. If sin a° = four fifths and segment DE measures 30 units, how long is segment EF?
triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees
15.5 units
24 units
30 units
37.5 units
Answer:
24 units
Step-by-step explanation:
From the description:
angle D measures a degreesopposite to angle D is side EFside DE (which measures 30 units) is the hypotenuse of the triangle.We also know that
sin(a) = 4/5
From definition:
sin(a) = opposite/hypotenuse
Replacing:
4/5 = EF/DE
EF = (4/5)*DE
EF = (4/5)*30 = 24 units
The length of the segment EF of the triangle DEF is 24 units.
Procedure - Determination of the resulting length after dilating a triangle by a scale factorIn the image attached below we summarize the triangle described in statement, by trigonometric relationship we find that the length of the segment EF is described by the following expression:
[tex]\sin a^{\circ} = \frac{EF}{DE}[/tex] (1)
If we know that [tex]DE = 30[/tex] and [tex]\sin a^{\circ} = \frac{4}{5}[/tex], then the length of the segment EF is:
[tex]EF = DE\cdot \sin a^{\circ}[/tex]
[tex]EF = 30\cdot \left(\frac{4}{5} \right)[/tex]
[tex]EF = 24[/tex]
The length of the segment EF of the triangle DEF is 24 units. [tex]\blacksquare[/tex]

2 (p^2 + p - 2)
2 (p^2 + 2p - p - 2)
2(p x (p+2) - (p+2)

P=2l+2w. solve for w. show all steps. please
Answer:
Step-by-step explanation:
You need to get w on one side by itself.
Start out by subtracting 2l from both sides.
p−2l=2w.
Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.
w=p2−I
Answer:
W=P-L
Step-by-step explanation:
P=2L+2W
Subtract 2L from both sides.
P-2L=2W
Divide both sides by 2
P-L=W

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that Five workers dig a trench 5 yards long in 5 hours.
We need to find workers are needed to dig a 100 yards long in 100 hours.
5 workers dig , 5 yards long = 5 hours.
1 yards long = 1 hours.
Thus, 100 workers dig a 100 yards long in 100 hours.

A copy machine is set up to enlarge an original in the ratio 2:3.
What is this enlargement in percent?
Answer:
It should be about 67%.
Step-by-step explanation:
The ratio 2:3 is the same as the fraction 2/3.
2 divided by 3 is equal to 0.66666...
When it is rounded to the hundredths place, it is 0.67.
This means that the percentage is 67%.
Answer:
The enlarged object would be 150% larger, but the enlargement itself makes the new picture 50% larger than before as the previous size was already considered 100%.
Step-by-step explanation:
It is much easier to picture this with nice numbers.
Let's say you start with a paper that is size 100 (these numbers have no real meaning they are just for illustrating a point), this would be the 2 in the ratio so the equality would look like: [tex]\frac{2}{3}[/tex]=[tex]\frac{100}{x}[/tex]. At this point you can cross multiply and divide, getting 2x=300. By dividing by 2, you get x=150.
Now percents are out of 100, and you have one of those, only right now it is on the top. All you have to do is flip the fraction, you get [tex]\frac{150}{100}[/tex]=150% is how much it was enlarged when compared to the original, it got 1.5 times larger (you can flip the fraction because you are looking to see how much bigger it got in relation to the starting size).
However, if you are looking for only the enlargement as a percent of the total the answer would be 50% since the new size 150 is 50 larger than 100 and [tex]\frac{50}{100}[/tex]=50%.
