What is the sum of -19 and — 76?
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

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
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

Does the table of values below represent a linear function, exponential function, or neither. Explain how you know.
Answer:
The given function neither represents the linear function nor represents an exponential function.
Step-by-step explanation:
Given the table
x y
0 2
2 4
4 8
6 16
Linear Function has the following characteristics:
The constant change in x and y
Exponential Function has the following characteristics:
The constant change in x The constant ratio in yDetermining the nature of the function
Given the table
x 0 2 4 6
y 0 4 8 16
Linear Function has the following characteristics:
The constant change in x and y
Checking the constant change in x
i.e. 2-0 = 2, 4-2 = 2, 6-4 = 2
Thus, there is a constant change in x values.
Checking the constant change in y
4-0 = 4, 8-4 = 0, 16-8= 8
Thus, there NO constant change in y values.
Therefore, the given function DOES NOT represent the linear function.
Determining if the given function is Exponential function or not.
CHECKING THE CONSTANT CHANGE IN X VALUE
i.e. 2-0 = 2, 4-2 = 2, 6-4 = 2
Thus, there is a constant change in x values.
Checking the CONSTANT RATIO
4/0=∞, 8/4 = 2, 16/8 = 2
It is clear that there is no constant ratio.
Therefore, the given function DOES NOT represent the exponential function.
Conclusion:
Thus, the given function neither represents the linear function nor represents an exponential function.

A speck of dust 8.2 x 10^ -7 m wide. Which of the following is the best way to rewrite this quantity, using more appropriate units A. 8.2 x 10^ -10 km B.8.2 x 10^ -7 m C. 8.2 x 10^ -5 cm D. 8.2 x 10^ -4 mm
Answer:
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
