Answer:
8 km
Step-by-step explanation:
It is given that, the scale of a map says that 8 cm represents 5 km. We need to find the actual number of kilometers that is represented by 5 centimeters on the map.
8 cm = 5 km
1 cm = (8/5) km
For 5 cm, multiply (8/5) km by 5.
So,
x = 8 km
So, 8 km is represented by 5 centimeters on the map.
The slope of a line is -1/5 and the y-intercept is 5. What is the equation of the line written in slope-intercept form? Type the equation in the space provided. Be sure to use the slope-intercept form noted in the lesson.
Answer:
y= -1/5x + 5
Step-by-step explanation:
An easy way to remember which one is the slope and which one is the intercept in a slope-intercept equation is that the number next to x is always the slope and the number that's a loner is the y-intercept. Hope this helps!
What is the difference between Glasgow and Copenhagen. (Glasgow= -7.8 Copenhagen=-3.8)
Answer:
Step-by-step explanation:
The difference of the two values is 4 as calculated by subtraction.
An arithmetic operation called subtraction is the process of deleting or removing items from a collection. The negative symbol (-) denotes subtraction.
Subtraction can mean eliminating or lowering physical and abstract quantities utilizing a variety of things, such as fractions, matrices, vectors, irrational numbers, decimals, functions, and however negative integers. it is typically linked with natural numbers in mathematics.There are several significant patterns in subtraction. It is anticommutative, which means that altering the sequence alters the answer's sign. Additionally, it is not associative, which means that when subtracting more than two numbers, the method used matters. 0 is the additive identity, hence subtracting it has no effect on a number. In relation to related operations like addition and multiplication, subtraction also abides by predictable principles.The given values for Glasgow and Copenhagen are given as -7.8 and -3.8 .
Therefore difference = -3.8 - (-7.8) = -3.8 +7.8 = 4

What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Given,
Diameter of structure = 9 × 10⁻⁹ meter
Multiply and divide by 10⁹
Diameter of structure = 9 × 10⁻⁹ × 10⁹/ 10⁹
By the law of indices
Diameter of structure = 9/10⁹
Diameter of structure = 0.000000009
Hence "The correct answer to the following question will be 0.000000009".

4n + 3 < 6n + 8 - 2n
Pls solve in steps
Answer:
All real numbers would be the correct answer.
Step-by-step explanation:
First of all, add 6n to -2n which now the equation would be 4n+3 < 4n+8.
Now, subtract 4n to both sides and subtract 3 to both sides. Now you will have 0n < 5 which will be all real numbers.

Consider the equation:
4(2 + px) = 12x
For what value of p does the equation have no solution?
A 1
B. 3
C 12
D. 48
Answer:
p = 3
Step-by-step explanation:
Given
4(2 + px) = 12x
If the coefficient of the x- term is the same on both sides of the equation, it will have no solution.
Distributing gives
8 + 4px = 12x ( equate the coefficients of the x- term )
4p = 12 ( divide both sides by 4 )
p = 3
The value of p when the equation has no solution will be 3. Then the correct option is B.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
4(2 + px) = 12x
8 + 4px = 12x
If the coefficient of the x-term is the same on both sides of the equation, it will have no solution.
4p = 12
p = 3
The value of p when the equation has no solution will be 3. Then the correct option is B.

Answer:
D, 110$
Step-by-step explanation:
According to the systematic function, given that the bill as a function is equal to one tenth the quantity of x for kilowatt hours less than or equal to 200, and three twentieths of 200 less than the quantity of x plus 20 for kilowatt hours greater than 200. The answer is 110$ because the question gives us a measure of kilowatts greater than 200 so the second equation is used in the system. Therefore .15(800-200) + 20 = b(800), (.15)600 +20 = 90 + 20 = 110

250/9.99=25.0250... Round it to 25.03
The required converted value is $25.03, which is 250 pesos to U. S. dollars.
As we all know, unit conversion is the process of multiplying a provided quantity by a conversion factor that combines the two interconnected units.
To convert 250 pesos to U.S. dollars, we divide the amount of pesos by the exchange rate.
Here, the exchange rate is given as 9.99 pesos per U.S. dollar.
It is the process of assigning a quantity from one unit of measurement to another.
250 pesos / 9.99 pesos per U.S. dollar = 25.025 U.S. dollars
Rounding this to two decimal places, the conversion is approximately $25.03.
Therefore, the correct option is (d) $25.03.
