The library had 202 shelves of books. Each shelf had 14 books. Librarians checked out 907 books to students. How many books does the library have remaining? PLZ WORTH 25 POINTS
Answer:
1921 books remaining.
Step-by-step explanation:
This library is fairly organized, so each shelf only has 14 books. Now with 202 shelves, we multiple the shelves by the amount of books per shelf.
202x14=2,828
Now, with 2828 books in the library before being checked out, we need to find out how many books left after the students came.
2828-907=1,921
The answer is 1,921 books remaining.
Hope this helps!

Answer:
the line plot in the bottom right corner
Step-by-step explanation:
Answer:
D is the correct graph.
Step-by-step explanation:
First you put the entries in ascending order, because that's how the line plot needs to be ordered.
1/4, 3/8, 1/2, 3/4, 7/8, 1, 1 1/4
So right there, you can rule out A.
You can rule out C because 1/4 does not occur 5 times in the data set.
B is incorrect because 3/8 isn't on the line plot at all.
Please let me know if you have questions.

Find the area of the shaded region of the square, with side length 2x - 3, if each of
the ovals has an area of x – 5 square inches.
Answer:
4x^2 - 14x + 19
Step-by-step explanation:
A = LW
A = (2x-3) (2x-3)
4x^2 - 6x - 6x + 9
Combine like terms:
4x^2 - 12x + 9
-2(x - 5) (for both ovals)
(4x^2 - 12x + 9) -2(x - 5)
4x^2 - 12x + 9 - 2x + 10
Group then combine like terms:
4x^2 - 12x - 2x + 10 + 9
4x^2 - 14x + 19

Step-by-step explanation:
When the central angles are congruent, the corresponding triangles are congruent:
ΔJHK ≅ ΔLHM . . . . selection E
and the base chords are congruent:
ML ≅ JK . . . . selection B
The subtended arcs are also congruent, so adding arc LK to each will result in congruent arc measures:

The population P, of Caribou in the Yukon is modeled by P=6x^2-120x+1250 where X is the number of years from today. After how many years with the Caribou population route 21,000 round to one decimal place
Answer:
It will take approximately 68.2 years for the Caribou population to reach 21,000.
Step-by-step explanation:
The population P of Caribou in the Yukon is modeled by P=6x²-120x+1250 where x is the number of years from today.
If the population P of Caribou in the Yukon is 21000, then, replacing you get:
21000= 6x²-120x+1250
So:
0= 6x²-120x+1250 -21000
0= 6x²-120x - 19750
This is a quadratic function of the form: 0= ax²+ bx +c, where: a=6, b= -120 and c=-19750
To solve a quadratic function and determine the value of x you can use the expression:
[tex]x1,x2=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]
Replacing the values of a, b and c and solving you get:
[tex]x1,x2=\frac{-(-120)+-\sqrt{(-120)^{2}-4*6*(-19750) } }{2*6}[/tex]
[tex]x1,x2=\frac{120+-\sqrt{14400+474000 } }{12}[/tex]
[tex]x1,x2=\frac{120+-\sqrt{488400 } }{12}[/tex]
[tex]x1,x2=\frac{120+-698.86 }{12}[/tex]
So:
[tex]x1=\frac{120+698.86 }{12}[/tex]
x1= 68.24 ≅ 68.2
and
[tex]x2=\frac{120-698.86 }{12}[/tex]
x2= -48. 24 ≅ -48.2
As time cannot be negative, it will take approximately 68.2 years for the Caribou population to reach 21,000.

The parabola is swached vertically by a factor of 5.
Answer:
answer below
Step-by-step explanation:
I think you mean "squashed" or "stretched" vertically by a factor of 5.
f(x) is the original parabola equation
g(x) = 5f(x) is vertically stretched by a factor of 5
(x,y) -> (x , 5y)
If two lines are parallel and they are defined by the equations, y=4x-5 and y=ax+2, what is the value of a?
Answer:
[tex]a=\dfrac{4x-7}{x}[/tex]
Step-by-step explanation:
The equations of lines are :
y=4x-5 and y=ax+2
From above equations,
4x-5 = ax+2
4x-ax = 5+2
4x-7 = ax
[tex]a=\dfrac{4x-7}{x}[/tex]
So, the value of a is equal to [tex]\dfrac{4x-7}{x}[/tex].

There about fifteen hundred players in the nfl in a survey of a random sample of 50 players three players were hurt how many players in the nfl would be excpected to get hurt
Answer: 90 players.
Step-by-step explanation:
Since we are informed that in a survey of a random sample of 50 players, 3 players were hurt. This gives a fraction of 3/50 for those that are hurt.
Therefore, in a survey of 1500 players, the number of players expected to be hurt will be:
= 3/50 × 1500
= 90
Barry the Beaver gnaws his way through a circular section of wood. The sector has a radius of 5.90 m and central angle 85.3°. What is the area of this section of wood?
Answer:
25.899sq.metres
Step-by-step explanation:
Area of this section of wood = Area of the sector
Area of the sector = theta/360 * πr²
r is the radius
theta is the central angle
Substitute
Area of the sector = 85.3/360 * πr²
Area of the sector = 85.3/360 * 3.14(5.90)²
Area of the sector = 85.3/360 * 109.3034
Area of the sector = 9,323.58002/360
Area of the sector = 25.899
Hence the area of the section of wood is 25.899sq.metres
in a random School sampling of 50 middle school students it was found that 18 students bring their lunch to school everyday if there are 942 students in the school predict how many bring their lunch to school each day
Answer:
340
Step-by-step explanation:
We can see in the sample that 18/50 people bring lunches to school. If we divide 18 by 50 we get 0.36 now we know that 36% of people bring their lunches in the sample. Now we take that number and multiply it by 942.
0.36*942= 339.12 which we can round to 340

Create an equation that models the total number of calories Jonathan consumes,y,based on number of biscuits he eats,x,and the 6 packages of pemmican
An equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're specified that:
x = number of buiscuits Jonathan eastsy = number of calories Jonathan consumes6 = number of packages of pemmican that jonathan consumes.Let we take:
m = number of calories per buiscuit that Jonathan eats.
Then, for x buiscuits, it would be [tex]m \times x[/tex] calories, or in short [tex]mx[/tex] calories.
Let k = number of calories per package of pemmican, then:
for 6 packages of pemmican, it would be [tex]6 \times k[/tex] calories, or in short [tex]6k[/tex] calories.
Thus, total calories Jonathan consumes = y = calories from x buiscuits + calories from 6 packages of pemmican.
or, we get:
[tex]y = mx + 6k[/tex]
Thus, an equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.

As part of statistics project, math class weighed all the children who were willing to participate as shown below.
How many children weighed less than 50 pounds?
Answer:
18
Step-by-step explanation:
The key of this leaf stem-leaf plot is:
4 | 5 = 45
Therefore, the data points that represents children with weight that is less than 50 pounds would be as follows:
First row => 12, 13, 15, 15 15, 16, 16, 19
Second row => 23, 25
Third row => 33, 35, 37, 38, 39
Fourth row => 44, 45, 45
Therefore, the number of children that weigh less than 50 pounds = 18
