How I find a area of a trapezoid
can someone please help me
Answer:
1a. 58/99
1b. 53/90
1c. 29/50
Step-by-step explanation:
let's start with the easiest one
1.(c)
0.58 = 58/100 = 29/50
that is the simplest possible form, as 29 is a prime number and not a factor of 50.
1.(a)
0.585858585858... = 58×0.0101010101010101...
now, we know that 1/"double digit" (like 1/22) mostly produces a repeating pattern with a period length of 2 after the decimal point.
and we find
1/99 = 0.01010101010101...
so, our solution is
58 × 1/99 = 58/99
that is the simplest possible form, as 58 and 99 do not share any factors.
1.(b)
0.5888888888888... = 0.5 + 0.0888888888888... =
= 0.5 + 8×0.01111111111111... = 0.5 + 8×1/10 × 0.1111111111...
we know how to create 0.11111111111... :
1/9 = 0.111111111111111...
so, our solution is
0.5 + 8 × 1/10 × 1/9 = 0.5 + 8/90 = 5/10 + 8/90 =
= 45/90 + 8/90 = 53/90
this is the simplest possible form, as 53 is already a prime number and not a factor of 90.
A balloon containing 0. 040 mol of a gas with a volume of 5. 0 mL was expanded to 1. 0 L. Which equation should you use to find the amount of gas added? V subscript 2 equals StartFraction V subscript 1 n subscript 2 over n subscript 1 EndFraction. N subscript 2 equals StartFraction V subscript 2 n subscript 1 over V subscript 1 EndFraction. N subscript 2 equals StartFraction V subscript 1 n subscript 1 over V subscript 2 EndFraction.
Answer:
n2=v2n1/v1
Or B
Step-by-step explanation:
P, R, and T are constant, then the volume is directly proportional to the mole. Then the correct option is A.
What is an ideal gas equation?An ideal gas is a theoretical composed of a set of randomly moving gas particles that interacts only through elastic collision.
Given
A balloon containing 0.040 mol of a gas with a volume of 5.0 mL was expanded to 1.0 L.
[tex] \rm V_1 = 5 \ mL\\ V_2 = 1000 \ mL\\ n_1 = 0.040 \ mol [/tex]
We know the equation of the ideal gas.
[tex] \rm PV = nRT [/tex]
where P, R, and T are the constant, then
[tex] P \propto n[/tex]
Then we have
[tex] \rm \dfrac{V_2}{V_1} = \dfrac{n_2}{n_1} \\\\ V_2 = n_2 *\dfrac{V_1}{n_1} [/tex]
Thus, the correct option is A.

Review the equation below. 2KClO3 Right arrow. 2KCl + 3O2 How many moles of oxygen are produced when 2 mol of potassium chlorate (KClO3) decompose? 1 2 3 6
Answer: 3 mol of O₂
Solution:
The Balance chemical equation is as follow,
2 KClO₃ → 2 KCl + 3 O₂
According to this equation on decomposition 2 moles of Potassium chlorate (KClO₃) produces 2 moles of Poatassium chloride (KCl) and 3 moles of oxygen gas (O₂).
Therefore, when,
2 moles of KClO₃ produces = 3 moles of O₂
So,
2 moles of KClO₃ will produce = X moles of O₂
Solving for X,
X = (2 mol × 3 mol) ÷ 2 mol
X = 3 mol of O₂
Using above method you can calculate any amount of O₂ or KCl produced by decomposing any amount of KClO₃.
Answer:
3 mol of O₂

Classify each pair of numbered angles. Drag and drop the descriptions into the boxes to correctly classify each pair of numbered angles. Each description may be used more than once. Two lines intersect. The largest angle has the equation (3x minus 52) degrees to define it and the second to largest angle has the equation (2x plus 2) degrees to define it. A straight line with another line coming out of it at an angle. The largest angle has the equation (10x minus 20) degrees to define it and the smaller angle has the equation (6x plus 8) degrees to define it.
(i) Pairs of neighboring angles are supplementary and opposite angles have the same measure.
(ii) The two angles formed by a line coming out of another line are supplementary.
How to analyze pairs of angles
(i) When two straight lines pass through each other, then two pairs of opposite angles are constructed. A pair with angles of [tex](3\cdot x + 52)^{\circ}[/tex] and another pair with angles of [tex](2\cdot x + 2)^{\circ}[/tex], each pair of angles with different measures are supplementary.[tex]\blacksquare[/tex]
(ii) When a straight line comes out of another straight line, from a point distinct to any endpoint of the former, then we construct two supplementary angles. The largest angle has a value of [tex](10\cdot x + 20)^{\circ}[/tex], whereas the smaller one has a value of [tex](6\cdot x + 8)^{\circ}[/tex]. [tex]\blacksquare[/tex]

The expressions that are equivalent to 4 × -3 are A) -12 and C) 2 × -6.
What is the expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
Option A is a straightforward multiplication of 4 and -3, which gives -12.
Option C (2 × -6) is equal to -12.
Option B can be simplified as follows: (-4) - (-4) · (-4) = (-4) - 16 = -20.
Therefore, option B is not equivalent to 4 × -3.
Option D is equal to 1/64.
Option E is equal to 1.
Option F is equal to 2, and option G is equal to 12.
Options B, D, E, F, and G are not equivalent to 4 × -3.

which of the following polynomials has a graph with odd symmetry? a. 7x^4+13x^3-11 b. 5x^7+4x^6+3x^5+x c.13x^5 -1/2x^3+7x+3 d. 8x^5+7x^3-5x
Answer:
D) [tex]f(x)=8x^5+7x^3-5x[/tex]
Step-by-step explanation:
A function is odd if its graph is symmetric to the origin, which we can check this if [tex]f(-x)=-f(x)[/tex] is true:
Option A
[tex]f(x)=7x^4+13x^3-11\\\\f(-x)=7(-x)^4+13(-x)^3-11\\\\f(-x)=7x^4-13x^3-11[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option B
[tex]f(x)=5x^7+4x^6+3x^5+x\\\\f(-x)=5(-x)^7+4(-x)^6+3(-x)^5+x\\\\f(-x)=-5x^7+4x^6-3x^5+x[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option C
[tex]f(x)=13x^5-\frac{1}{2}x^3+7x+3\\\\f(-x)=13(-x)^5-\frac{1}{2}(-x)^4+7(-x)+3\\ \\f(-x)=-13x^5-\frac{1}{2}x^4-7x+3[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option D
[tex]f(x)=8x^5+7x^3-5x\\\\f(-x)=8(-x)^5+7(-x)^3-5(-x)\\\\f(-x)=-8x^5-7x^3+5x[/tex]
Since [tex]f(-x)=-f(x)[/tex], then the function DOES have odd symmetry. You can also see that the function is odd because every term has an odd exponent.

yall HELP PLEASE What is the slope of the line segment?
Answer:
a. 5
Step-by-step explanation:
Taking two points, (0,0) and (1,5), find the slope using [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Plugging the two points in, we have [tex]\frac{5-0}{1-0}=5[/tex] as the slope.
Answer:
Slope = 5
Step-by-step explanation:
We will use 2 points on the line.
(1 , 5) and (2 , 10)
formula for slope = y2 - y1/x2 - x1
10 - 5/2 - 1
= 5/1
= 5
The slope is 5.
Layla read 6 books in the first two months she was a member of a book club. Which equation best represents y, the total number of books read in x number of months?
A. y = 6x
B. y = 2x
C. y = 3x
D. Not Here
Answer:
C
Step-by-step explanation:
So if we look at the information that we already know, Layla's reading to months ratio is, 6:2. But to find out the equation we want to find out how many books she reads in ONE month instead of two.
Divide 2/2, and for ratios if you divide one side you have to do the same thing to the other side, so we get, 3:1. Where Layla reads 3 books per 1 month.
Therefore the answer is C.
If we wanted to double check our answer we could substitute our information back in:
6=3×2
6=6
Since the equations equal each other, we know we got it correct.
What is the conversion factor for the relationship between millimeters and centimeters?.
Answer:
10 mm = 1 cm
Step-by-step explanation:
10 mm = 1 cm
__
The SI prefix "milli-" means 1/1000. The prefix "centi-" means 1/100. Consequently 1 cm = 0.010 m and 1 mm = 0.001 m.
There are 10 mm in 1 cm.
