Step-by-step explanation:
It's d credit to the person who said it
The best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer
What is conversion?The process of changing the value of one form to another is called conversion. It doesn't affects the value, it simply converts one form to another.
Now it is given that,
Width of a speck of dust = 8.2 x 10⁻⁷ m
Since, 1 kilometer = 1000 meters = 10³ meters
Therefore, 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷ x 10³ kilometer
⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷⁺³ kilometer
⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁴ kilometer
Thus, the best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

The wholesale cost for a purse in a department store is $12.50. The store plans to mark up the purse by 140%. What will be the selling price of
the purse to the nearest cent?
Give me the right anwser
Answers
Answer:
$30.00
Step-by-step explanation:
Percentage Markup formula =
Selling price - Cost price/Cost price × 100
From the question:
Cost price = $12.50
Selling price = unknown = x
Percentage Markup = 140%
140% = x - $12.50/$12.50 × 100
140/100 = x - $12.50/$12.50
1.4 = x - $12.50/$12.50
Cross Multiply
1.4($12.50) = x - 312.50
$17.50 = x - $12.50
x = $17.50 + $12.50
x = $30.00
Therefore, the selling price of the purse is $30.00

Step-by-step explanation:
Look at the graph they gave you. ... At first it looks like an ugly mess.
But look closer. There are only two lines there that go through the origin,
so one of those is the answer to the question.
Now let's talk about the slope of a line.
-- If the slope of a line is positive, that means it rises as it goes.
If you walk the graph from left to right, you're climbing.
-- If the slope of a line is negative, that means it falls as it goes.
If you walk the graph from left to right, you're going down-hill.
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2 . That's positive.
The line on the graph slopes up. To walk it, you have to climb.
In the picture, that can only be line 'c' .
Answer:
The equation they gave you is [ y = 1/2 x ].
The slope is 1/2. That's positive.
The line on the graph slopes up. To walk it, you have to climb.

Given the quadratic equation x²−7x+10
To factor this expression, we need to get two values if when multiplied will give 10 (product of the coefficient of x²and the constant term) and the sum will give -7(coefficient of x).
The two values are:
-2 and -5
-2 * -5 = +10-2-5 = -72 and 5

A circle with center B and radius 1cm has three distinct points, F, D and E, on its circumference so that BF and BE and D is on the minor arc FE. Point A is on BF so that DA and BF. The point C is on BE so that ABCD is a rectangle and the distance from C to E is 1cm. Determine the distance from A to F.
Answers
Answer:
8 cm
Step-by-step explanation:
A circle with center B and radius 13 cm has three distinct points, F, D and E, on its circumference so that BF and BE and D is on the minor arc FE. Point A is on BF so that DA is perpendicular to BF. The point C is on BE so that ABCD is a rectangle and the distance from C to E is 1cm. Determine the distance from A to F.
Solution:
Since the radius of the circle is 13 cm, hence:
BF = BD = BE = 13 cm.
For line segment BE; BE = BC + CE
BE = BC + CE
13 = BC + 1
BC = 13 - 1
BC = 12 cm
AD = BC = 12 cm (opposite sides of a rectangle are equal to each other)
Triangle ABD, is a right angled triangle because ∠B = 90°. We can use Pythagoras theorem to find AB:
BD² = AB² + AD²
13² = AB² + 12²
169 = AB² + 144
AB² = 169 - 144
AB² = 25
AB = √25 = 5
For line segment BF, we can use the line segment addition postulate to find the distance from A to F. Let x be the distance from A to F:
BF = AB + x
x = BF - AB
x = 13 - 5
x = 8 cm

What is the sum of -19 and — 76?
Answers
Answer:
-95
Step-by-step explanation:
The solution is -95
The value of the equation A = -16 + ( -76 ) is A = -95
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = the sum of -19 and -76
On simplifying the expression , we get
A = ( -19 ) + ( -76 )
On simplifying the equation , we get
A = -19 - 76
The value of A = -95
Therefore , the value of A is -95
Hence , the solution of sum of -19 and -76 is -95
