1.6
1.6 miles per hour is speed of Rafael.
What is Speed?speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, Rafael is going for a walk. He takes 4 hours to walk 6.4 miles.
From the general formula of speed:
Speed = distance/time
In our case,
Distance= 6.4 miles
Time = 4 hours
Thus,
Speed = 6.4/4
Speed in miles per hour = 1.6
therefore, the speed of Rafael is 1.6 miles per hour.

Step-by-step explanation:
The correct answer to the following question will be 0.000000009 so answer (F) will be correct.
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".

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

Step-by-step explanation:
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.

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.

3 quarts of apples juice for $3.59 OR 1 gallon (4 quarts) of apple juice for $3.99
Answer:
1 gallon is the better deal
Step-by-step explanation:
If you divide 3.99/4 you get 0.9975. Therefore, a quart of apple juice costs 0.9975. If you divide 3.59/3, you get 1.19 which is more expensive than 0.9975. The answer is 1 gallon of apple juice for 3.99 is the better deal.

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.

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.
