A bookshelf has 36 fiction books and 44 non-fiction books. What percentage of the total books are non-fiction?
Answer:
55% of the total books are non-fiction.
Step-by-step explanation:
There are a total of 80 books, and there are 44 non-fiction books among them.
Divide 44 by 80, then multiply by 100 to get the percentage.
(44/80) × 100 = 55%

Answer:
10218.75
Step-by-step explanation:
You should divide the two shapes into a rectangle and a triangle, find the area of each, then add them together like so:
For the rectangle:
37.5*22.5 = 843.75
For the triangle:
To find the base: 75 - 37.5 = 37.5
To find the height, use pythagoream theorem.
62.5² = 37.5² + b²
3906.25 = 1406.25 + b²
3906.25 - 1406.25 = 2500
√2500 = 50.
The height is 50, so 50*37.5(1/2)
= 937.5
Now add them together
937.5 + 843.75
Solve for a. -4a - 2a – 7 = 11 a = [?]
Answer:
a = -7/17
Step-by-step explanation:
Add -4a to -2a
This makes -6a. Then you add 6a to the left to cancel it out, but you must also add 6a to the right of the =
Then you have -7 = 17a
Divide 17 from both sides and you have -7/17 = a

What’s the length of a segment whose endpoints are (8,-6) and (-4,2)?
Answer:
Step-by-step explanation:
Imagine or draw a triangle with horizontal leg length 8 - (-4), or 12, and vertical leg length |-6 - 2|, or 8. Use the Pythagorean Theorem to find the length of the hypotenuse:
length of hypotenuse = +√(8² + 12²) = √208 = 4√13 (Answer A)

The temperature in Calgary at 9 a.m. was – 23 C.
By 11 a.m., it had warmed up by 8 C.
By noon, it had warmed up by another 3 C.
But by 2:00 p.m. it had cooled by 6 C.
What was the temperature in Calgary at 2:00 p.m.?
Answer:
-18 C°
Step-by-step explanation:
Warmed means add cooled means subtract
starting at -23 it warmed by 8 add 8
-15
it warmed by 3 more add 3
-12
then it cooled by 6 subtract 6
-18
What is the value of x? Show me how you got that answer.
Answer:
x = 3
Step-by-step explanation:
The angle measuring 5x and the angle measuring 165° are a linear pair, so they are supplementary. Their measures add to 180°.
5x + 165 = 180
5x = 15
x = 3
Probability mathematic
Answer:
1/9
Step-by-step explanation:
Probability = Expected outcome/Total outcome
From the given pi chart,
Total outcome = 360degrees (since the total angle in a circle is 360 degrees)
Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;
Expected outcome = 40degrees
Pr(scoring a 5) = 40/360
Pr(scoring a 5) = 1/9
Hence the probability of scoring a 5 is 1/9
Answer:
1/9
Step-by-step explanation:
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Divide the number of events by the number of possible outcomes.

A pattern is made from four congruent squares.
The sides of the squares are parallel to the axes.
N
Point A has coordinates (3, 2)
YA
B (27, 30)
Point B has coordinates (27, 30)
Point C is marked on the diagram.
Work out the coordinates of C.
Answer:
(13, 16)
Step-by-step explanation:
Point A has coordinates (3,2) Point b has the coordinates (27,30)
Therefore the width of the diagram = 27 - 3 = 24 units and the height of the diagram = 30 - 2 = 28 unit
The length of the square = 28 unit / 4 square = 7 unit
Also, half of the height of the diagram = 28/2 = 14 unit
Therefore the x coordinate is given by:
27 - (2 × 7) = 27 - 14 = 13 or 27 - 14 (=13) or 3 + 7 + (24 - 3 × 7) = 13
Also, the y coordinate is given by:
30 - (2 × 7) = 30 - 14 = 16 or 30 - 14 (=16) or (30 + 2)÷2 = 16
Therefore the coordinate for point C is given by (13, 16)

Check if (1,6) is the solution to the system shown below.
Answer:
NO it is not
Step-by-step explanation:
To check that, we will need to substitute the value of each of the coordinates in each of the equations
10x-y = -6
substitute 1 for x and 6 for y
we have this as;
10(1)-6 = 4
Outrightly, we can see that the given point is not a solution to the given system of equations
however, let us confirm for the second
We have this as;
-10(1) + 5(6)
= -10 + 30 = 20
so we can confirm that it does not work for any of the two and our answer is NO

Find the volume of the cylinder in terms of x and to the nearest tenth
Answer:
12.57 in^3
Step-by-step explanation:
The easiest way to do this is to find the area of the circle surface and multiply it by the height
to find area the formula is pi r^2 and we are given the radius
so we plug in pi(2^2)=pi(4)= roughly 12.57
then we multiply the area by the height which is 1 so it would be the same
12.57(1)=12.57
