108 identical books have a mass of 30 kg. Find
(i) the mass of 150 such books,
(ii) the number of such books that have a mass
of 20 kg.
Answer:
The mass of 150 books = 41.7kg
The number of books that have mass 20kg = 72 books
Step-by-step explanation:
(I) Number of identical books = 108
Mass of books = 30 kg
Mass of 150 books = ?
Let the mass of 150 books = x kg
To find the mass of 150 books we will use ratio and proportion:
108 books: 30kg = 150 books: x kg
You can also write it like this because ratio can be written in division:
108/30 = 150/x
By cross multiplication:
108x = 150*30
108 x= 4500
Divide both sides by 108
108 x/108 = 4500/108
x= 41.7
Thus the mass of 150 books = 41.7kg
( ii ) The number of books that have a mass of 20 kg = ?
Let assume that the number of books of mass 20 kg = y books
We will again use ratio and proportion method.
108 books: 30kg = y: 20kg
We can write it as:
108/30 = y/20
By cross multiplication:
108 *20 = 30y
2160= 30y
Divide both the terms by 30
2160/30 = 30y/30
72 = y
Therefore the number of books that have mass 20kg = 72 books ....

Find the value of x and y.
A) x=12, y=10
B) x=14, y=11
C) x=14, y=10
D) x=12, y=11
This is for Geometry.
Answer:
The correct answer is first option
x = 12, y = 10
Step-by-step explanation:
From the figure we can see that a triangle ADC, and EB is parallel to side DC.
To find the value pf x
From the given figure we get,
<ABC = <BCD [ corresponding angles are equal]
3x + 9 = 4x - 3
4x - 3x = 9 + 3
x = 12
To find the value of y
<ABE and <EBC are linear pairs.
Therefore, <ABE + <EBC = 180
(3x + 9) + (14y - 5) = 180
(3 * 12 + 9) + 14y - 5 = 180
45 + 14y - 5 = 180
14y = 180 -40
14y = 140
y = 140/14 = 10
y = 10
Therefore x = 12 and y = 10
The correct answer is first option

The length of a rectangle is equal to triple the width.
Find the width of the rectangle if the perimeter is 80 centimeters.
Answer:
10 cm
Step-by-step explanation:
If the length of a rectangle is equal to triple the width, the width of the rectangle is 10 cm if the perimeter is 80 centimeters.
L = 3w
P = 80
Formula: a = l × w
8W = 80 cm
W = 80 / 8 = 10 cm
Therefore, the width of the rectangle is 10 centimeters.
The width of the rectangle is found to be 10 centimeters, obtained by solving the equation created based on the fact that the perimeter of a rectangle is 2(length + width) and the given data that length is thrice the width and perimeter is 80 cm.
Explanation:To figure out the width of the rectangle, we first need to understand the relationship between the length and width, and how they relate to the perimeter. The length of the rectangle is triple the width. Let's define the width as 'w'. Therefore, the length would be '3w'.
The formula for the perimeter of a rectangle is 2(length + width).
Given that the perimeter is 80 centimeters, we can set up the equation 2(3w + w) = 80. Simplifying this gives 8w = 80. To find the width 'w', we divide both sides of the equation by 8, giving us w = 10 centimeters.
Therefore, the width of the rectangle is 10 centimeters.

Answer:
C; The left end goes up; the right end goes down
Step-by-step explanation:
If you expand the function, you end up with a polynomial with a negative coefficient and it has an odd power. According to polynomial behaviors of a function that is odd negative, the graph will rise to the left (y → ∞ and x → -∞) and falls to the right (y → -∞ and x → ∞).
ANSWER
C. The left end goes up; the right end goes down.
EXPLANATION
The given function is
[tex]f(x) = - 2( {x - 2)}^{5} [/tex]
We analyze the end behavior of this function using the leading term.
The leading term of this function is:
[tex] - 2 {x}^{5} [/tex]
Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.
In other words, the left end of the graph goes up and the right end goes down.
The correct option is C.

[tex]\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}} \\\\ =\frac{6c^{2}+3c}{-4c+2} \times \frac{4c-2}{2c+1}\\\\=\frac{3c(2c+1)}{-(4c-2)} \times \frac{4c-2}{2c+1}\\\\ =-3c[/tex]
Thus, the given expression in simplified form is equal to -3c
Answer:
-3c
Step-by-step explanation:
We are given that an expression
[tex]\frac{\frac{6c^2+3c}{-4c+2}}{\frac{2c+1}{4c-2}}[/tex]

Name 3 ways that a parabola changes with different types of "a" values.
Answer:
Up down and side to side on the graph
Step-by-step explanation:
If a is 1, since it is positive the parabola moves up. If a is -1, since it is negative the parabola moves down. (not sure about side to side because I can't back that one up but I'm 100% sure about up and down)
When a is between 0 and 1, the parabola gets wider.
What is the parabola?A parabola is a mathematical curve that is defined by a point and a line. The point is known as the focus, and the line is called the directrix. The parabola has the property that all points on it are equidistant from the focus and the directrix.
Here,
When a is negative, the parabola flips 180°.
When |a| is less than 1, the parabola opens wider.
When |a| is greater than 1, the parabola opens more narrow.
When a is between 0 and 1, the parabola gets wider, when it is greater than 1, it gets narrower, and when it is less than 0 it is reflected across the x-axis.
Therefore, when a is between 0 and 1, the parabola gets wider.

If a circle has diameter endpoints at (-1,7) and (6,2), what is its center and radius
Answer:
The radius is [tex]\frac{\sqrt{74}}{2}[/tex].
The center is (5/2 , 9/2).
Step-by-step explanation:
The radius is half the diameter. We aren't given the length of the diameter but we are given endpoints to one of them.
So let's find the length of that diameter using the distance formula.
The distance formula is
[tex]d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex].
I just do big x minus small x or big y minus small y.
Anyways the points are (-1,7) and (6,2).
The x distance is 6-(-1)=7.
The y distance is 7-2=5.
So we have this using the distance formula so far:
[tex]d=\sqrt{(6-(-1))^2{(7-2)^2}[/tex]
[tex]d=\sqrt{7^2+5^2}[/tex]
[tex]d=\sqrt{49+25}[/tex]
[tex]d=\sqrt{74}[/tex]
So the radius is half that much because that was the distance between the endpoints of a diameter.
So the radius is [tex]\frac{\sqrt{74}}{2}[/tex].
Now the center of a circle will lie on the midpoint of a diameter, any given diameter.
We have the endpoints of one, so we just need to use midpoint formula.
Midpoint formula says the midpoint is (average of x, average y).
Midpoint formula: [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex].
So average of x's is (-1+6)/2=5/2.
The average of y's is (7+2)/2=9/2.
So the midpoint of the diameter or the center of the circle is at (5/2 , 9/2).

The probability of an event and its complement add up to 1. If the probability of an event is 0.3, the probability of its complement is 0.7.
Explanation:The probability of an event and its complement always add up to 1. So, if the probability of an event is 0.3, the probability of its complement can be calculated by subtracting the probability of the event from 1. In this case, the probability of the complement would be 1 - 0.3 = 0.7. Therefore, the probability of the complement is 0.7.

60 minutes
A. True
B. False
The correct option is b). The statement is False, it incorrectly describes the method for converting minutes to seconds.
To convert minutes to seconds, you multiply by 60 because there are 60 seconds in one minute.
So, to convert 5.25 minutes to seconds:
[tex]\[ 5.25 \text{ minutes} \times 60 \text{ seconds/minute} = 315 \text{ seconds} \][/tex]
Therefore, 5.25 minutes is equal to 315 seconds.
Regarding your original question about the statement:
To convert 5.25 minutes to seconds, you would use the ratio [tex]\( \frac{1 \text{ second}}{60 \text{ minutes}} \).[/tex]
This statement suggests using a ratio, which is not correct for converting minutes to seconds. Instead, you should use multiplication by 60 seconds per minute.
