A stock market index drops by 1.38 points. What rational number represent the change in the index
Answer:
The change in the index is - 69/50
Step-by-step explanation:
* Lets explain what is the rational number
- A rational number is a number that can be expressed as a fraction
a/b where a and b are integers and b ≠ 0
- A rational number have numerator and denominator
- Whole numbers, integers, fractions, terminating decimals and
repeating decimals are all rational numbers
- The rational numbers includes all positive numbers, negative
numbers and zero that can be written as a fraction
- To convert a Decimal to a Fraction follow these steps:
# Write down the decimal divided by 1
# Multiply both top and bottom by 10 for every number right the
decimal point
# Simplify (or reduce) the fraction
* Lets solve the problem
- A stock market index drops by 1.38 points
- We need to find the rational number represents the change in
the index
∵ Drop means the stock is become less
∴ The value of change will be negative
∵ The stock is drops by 1.38
∴ -1.38 = -1.38/1
- Multiply up and down by 100 because there are 2 digits right the
decimal point
∴ -1.38 = -138/100
- Divide up and down by 2
∴ -1.38 = - 69/50
∴ The change in the index is - 69/50 (-1.38)
Answer: [tex]\dfrac{69}{50}[/tex]
Step-by-step explanation:
A rational number is in the form of [tex]\dfrac{p}{q}[/tex] , where [tex]q\neq0[/tex]. and p and q are integers.
Given : A stock market index drops by 1.38 points.
To convert 1.38 into rational , we divide and multiply it by 100 ( 1.38 is decimal expression up to hundredth) , we get
[tex]1.38\times\dfrac{100}{100}=\dfrac{138}{100}[/tex]
Now , we divide numerator and denominator by 2 , we get
[tex]\dfrac{69}{50}[/tex]
Hence, the rational number represent the change in the index is [tex]\dfrac{69}{50}[/tex].

6 + 0 = 6, 8 + 0 = 8,9+ 0 = 9, 100 + = 100.
Conclusion:
Answer:
Any number plus 0 is the same as the first number.
Step-by-step explanation:
6 + 0 = 6, 8 + 0 = 8,9+ 0 = 9, 100 + 0 = 100.
Conclusion: Any number plus 0 is the number.
For example: x + 0 = x
x is the number.
Answer: 0
Step-by-step explanation:
100+0=100.
Just basic addition too. 100+0=100. That simple.
No other number can give off 100 like 0 can. 100 plus 0 just gives it the number itself.
Just like how 6+0=6. 6 is just being added to itself.
So, your answer for this is 0. No other number can give off a better answer than the 0 for this problem.

The music store sold 12 trumoets and 19 clarinets last month. If clariners sell for $139.95 and the store made $4,578.45 from sales on the two instruments, find the price of a trumphet.
Answer:
$159.95
Step-by-step explanation:
Let price of trumphet be defined by [tex]x[/tex]
price of clarinet = $139.95
Number of clarinets sold = 19
Earning through clarinets' sale = [tex]19*139.95 = 2659.05[/tex]
Total earning of store = $4578.45
Earning through trumphets' sale = [tex]4578.45 - 2659.05 = 1919.40[/tex]
price of one trumohet = [tex]\frac{1919.40}{12} = 159.95[/tex]
price of clarinet = $159.95

Find the slope and y-intercept of the line that is y=−2/3x+5 and passes through the point (−6,4)
Use the point-slope formula.
y - y_1 = m(x - x_1)
y - 4 = (-2/3)(x + 6)
y - 4 = (-2/3)x - 4
y = (-2/3)x - 4 + 4
y = (-2/3)x + 0
y = (-2/3)x
Slope = -2/3
y-intercept = 0, which means the x-axis.

Explain why the triangles are similar and write a similarity sta
atement.
Answer:
Because they are
Step-by-step explanation:
they ar4
Triangles are similar if their angles are congruent, supported by the AAA theorem. The similarity of triangles implies that the corresponding side lengths are proportional, which can be expressed algebraically or in words.
To justify that the triangles are similar, we look for congruent angles and proportional sides. The student indicated that the triangles have the same angles, which satisfies the AAA (Angle-Angle-Angle) similarity theorem. Because the angles are congruent, the sides are proportional, which means the ratios of corresponding sides are equal.
With words, we can express the relationship of corresponding lengths in similar triangles as the ratio of one triangle's side lengths to the other's. Algebraically, if we have corresponding sides a, b, and c from Triangle 1, and sides d, e, and f from Triangle 2, then a/d = b/e = c/f.
To solve for an unknown quantity, we algebraically isolate the variable in our equation, plug in the known values, calculate the answer, and then check to ensure the result is reasonable. For example, if we know sides a, b, d, and e, and we want to find side c, we would set up the proportion c/f = a/d, and after substituting the known values, we solve for c.
Kite EFGH is inscribed in a rectangle such that F and H are midpoints and EG is parallel to the side of the rectangle.
Which statements describes how the location of segment EG affects the area of EFGH?
A.) the area of EFGH is 1/4 of the area of the rectangle if E and G are not midpoints
B.) The area of EFGH is 1/2 of the area of the rectangle only if E and G are midpoints
C.) The area of EFGH is always 1/2 of the area of the rectangle.
D.) The area of EFGH is always 1/4 of the area of the rectangle.
Answer:
C
Step-by-step explanation:
EFGH is a kite, so EF ≅ FG and EH ≅ HG.
The area of the kite consists of two area of triangles EFG and EHG.
1. Area of triangle EFG:
[tex]A_{\trangle EFG}=\dfrac{1}{2}\cdot EG\cdot h,[/tex]
where h is the height drawn from point F to the side EG.
1. Area of triangle EHG:
[tex]A_{\trangle EHG}=\dfrac{1}{2}\cdot EG\cdot H,[/tex]
where H is the height drawn from point H to the side EG.
3. Note that
[tex]EG \cong \text{rectangle's length}[/tex]
[tex]h+H\cong \text{rectangle's width}[/tex]
So,
[tex]A_{\text{kite }EFGH}\\ \\=A_{\triangle EFG}+A_{\triangle EHG}\\ \\=\dfrac{1}{2}\cdot EG\cdot (h+H)\\ \\=\dfrac{1}{2}\cdot \text{rectangle's length}\cdot \text{rectangle's width}\\ \\=\dfrac{1}{2}A_{\text{rectangle}}[/tex]
Thus, option C is true (the area of the kite doesn't depend on ratio in which points E and G divide the side)
Answer:
C.) The area of EFGH is always 1/2 of the area of the rectangle.

(-11+ √-4) + (4+ √-36)
Answer:
[tex]-7 + 8i[/tex]
Step-by-step explanation:
[tex](-11 + \sqrt{-4}) + (4 + \sqrt{-36}) = (-11 + 2\sqrt{-1}) + (4 + 6\sqrt{-1})[/tex]
We know [tex]\sqrt{-1}[/tex] is a complex number and is defined by [tex]i[/tex]
∴[tex](-11 + \sqrt{-4}) + (4 + \sqrt{-36}) = (-11 + 2i) + (4 + 6i) = -7 + 8i[/tex]
The winner of a 50mile race drove his car to victory at a rate of 100.4893mph. What was his time (to the nearest thousandth of an hour)?
Answer:
His car's speed rate to the nearest thousandth of an hour is 100.489
Step-by-step explanation:
First: This is the only step, round the speed rate to the nearest thousandth:
When rounding always look at the place value they're telling you to round to and the place value to the right of it. Since, the question wants us to round to the nearest thousandth, look at the thousandths place but more specifically the place value to its right. The thousandths is the third digit behind the decimal point and the one to its right would be the fourth.
100.4893
So, if the number to the thousandths' right is less than 5 turn that number into a zero and keep the rest of the number the same. If the number is greater than or equal to 5 round up by making the number in the thousandths place a digit bigger.
Since 3 is smaller than 5, we'll turn the 3 into a zero and keep the rest the same.
100.4890
Since the zero is behind the decimal point and it is the number farthest to the left we can take it out.
100.489

Use the work shown below to write the equation for a line that has a slope of and passes through (15, –2). y = mx + b What is the equation of the line in slope-intercept form?
Answer:
y = -2
Step-by-step explanation:
You would use the Point-Slope Formula since we are given a point:
y - y₁ = m(x - x₁)
y + 2 = 0
y = -2
Because there was no rate of change [slope] given, it was automatically assumed to be a zero slope, which is a horizontal line.

A. x=9 or x=-3
B. x=7 1/2 or x=-3
C. x= 7 1/2 or x=9
D. x= 7 1/2 or x= -9 1/2
Answer:
a
Step-by-step explanation:
Given
2| x - 3 | + 5 = 17 ( subtract 5 from both sides )
2| x - 3 | = 12 ( divide both sides by 2 )
| x - 3 | = 6
The absolute value function always returns a positive value but the expression inside can be positive or negative, that is
x - 3 = 6 OR -( x - 3) = 6
x - 3 = 6 ( add 3 to both sides )
x = 9
OR
-( x - 3) = 6 ← distribute left side
- x + 3 = 6 ( subtract 3 from both sides )
- x = 3 ( multiply both sides by - 1 )
x = - 3
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.
x = 9 → 2|9 - 3| + 5 = 2|6| + 5 = (2 × 6) + 5 = 12 + 5 = 17 ← True
x = - 3 → 2|- 3 - 3| + 5 = 2| - 6 | + 5 = (2 × 6) + 5 = 12 + 5 = 17 ← True
Hence x = 9 or x = - 3 are the solutions → a
