Answer:

The common difference is 2.

Alex will take 3.75 gallons of fuel to drive five hours to visit his family in city B.

First, let's convert the rate of 60 kilometers per hour to miles per hour:

60 kilometers per hour * (1 mile / 1.6 kilometers) = 37.5 miles per hour

Next, we'll use the rate to find out how many miles Alex will drive in 5 hours:

37.5 miles per hour * 5 hours = 187.5 miles

Now that we know the total distance Alex will drive, we can use the information about the fuel consumption (2 gallons every 50 miles) to calculate the number of gallons of fuel he will need:

187.5 miles / 50 miles per 2 gallons = 3.75 gallons

So, Alex will need 3.75 gallons of fuel to drive five hours to visit his family in city B.

Step-by-step explanation:

Question 3

If  [tex]\dfrac{4}{5}[/tex] inches of rain falls every  [tex]\dfrac{2}{3}[/tex] hours then the unit rate in inches per hour is inches [tex]\div[/tex] hours

This would be:
[tex]\dfrac{\ensuremath{\dfrac{4}{5}\;in}}{\dfrac{2}{3}\;hr}[/tex]

This is the first option in Question 3 answer choices

Question 4

[tex]\dfrac{\dfrac{1}{4}\;km}{\dfrac{2}{5}\;min}[/tex]

is nothing but the numerator ÷ denominator which would be:

This is the third option in Question 4 answer choices

Question 5

[tex]\dfrac{1}{2} \div \dfrac{5}{7}\\[/tex]

Flip the divisor [tex]\dfrac{5}{7}[/tex]; it comes [tex]\dfrac{7}{5}[/tex]

Multiply:
[tex]\dfrac{1}{2} \times \dfrac{7}{5}[/tex]

The result is
[tex]\dfrac{7}{10}[/tex]

This is the second option in Question 4 answer choices

Answers:

Question 3: [tex]\frac{\frac{4}{5}in.}{\frac{2}{3}hr.}[/tex]

Question 4: [tex]\frac{1}{4}[/tex] ÷ [tex]\frac{2}{5}[/tex]

Question 5: [tex]\frac{7}{10}[/tex]

Explanations:

Question 3: We're told that rain is falling at a rate of  [tex]\frac{4}{5} in.[/tex] every  [tex]\frac{2}{3} hr.[/tex], and the unit rate we're looking for is inches per hour (or more precisely, inches per 1 hour). Based on these parameters, we know that you have to divide the unit inches by the unit hours. So using the numbers above, the correct complex fraction to represent this situation would be [tex]\frac{\frac{4}{5} in.}{\frac{2}{3} hr.}[/tex] .

Question 4: In this question, we are given a complex fraction and asked to rewrite it as a simple division problem. The complex fraction is [tex]\frac{\frac{1}{4} km.}{\frac{2}{5} min.}[/tex], so in order to write this as a division expression, you simply take the numerator fraction and divide it by the denominator fraction, which will end up being [tex]\frac{1}{4}[/tex] ÷ [tex]\frac{2}{5}[/tex]. Therefore, that will be your answer.

Question 5: Now, we have a division expression and are asked to use the Keep, Change, Flip method to solve the problem. First and foremost, the Keep, Change, Flip method is essentially telling you that when you are dividing by a fraction, you keep the dividend the same, you change the divisor - specifically switching the numerator with the denominator, which is creating the reciprocal of that fraction - and multiply by the reciprocal of the original divisor instead.

                   A good example of the Keep, Change, Flip method from above would be [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]. You keep the dividend, change the divisor, specifically flip the function around to create its reciprocal, and instead multiply by the divisor's reciprocal. Following those steps, [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]  will become [tex]\frac{1}{2}[/tex] × [tex]\frac{3}{1}[/tex] or [tex]\frac{1}{2}[/tex] × [tex]3[/tex].

                  Now that we understand how to use the Keep, Change, Flip method, we can use it to solve the expression [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{5}{7}[/tex]. We keep [tex]\frac{1}{2}[/tex] the same, flip [tex]\frac{5}{7}[/tex] to make its reciprocal, and multiply [tex]\frac{1}{2}[/tex] by that instead. So the final answer will be [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{5}{7}[/tex] = [tex]\frac{1}{2}[/tex] × [tex]\frac{7}{5}[/tex] = [tex]\frac{7}{10}[/tex].

Step-by-step explanation:

the slope is always the factor of x and the ratio

y coordinates difference / x coordinates difference

when going from one point on the line to another.

in short : y/x

the perpendicular slope is -x/y.

the ratio is turned upside down, and the sign is flipped.

so, the begin of our equation is

y = (1/3)x + b

b (the y-intercept, which is the y-value when x = 0) we get by using the given point and is coordinates:

-7 = (1/3)×6 + b = 2 + b

b = -9

so, the whole equation is

y = (1/3)x - 9

Step-by-step explanation:

To find the volume of this solid, we will use the method of cylindrical shells. We will integrate the cross-sectional area of the equilateral triangles over the height of the solid.

The height of the solid is given by the difference between the upper and lower bounds of the base, which are y = 4 and y = x^2, respectively. The cross-sectional area of an equilateral triangle with sides of length 2x is given by (x^2 * √3)/4.

So, the volume of the solid is given by the integral:

V = ∫[x^2, 4] (x^2 * √3)/4 dx

Using the antiderivative of x^2 * √3 / 4, which is (2x^3 * √3)/(12), we can find the definite integral:

V = [2x^3 * √3]/12 from x^2 to 4

Evaluating the definite integral and simplifying, we get:

V = 16 units^3

So, the volume of the solid is 16 units^3.

Answer:

the volume of the solid is 16 units^3

The number of arrangements of 6 balls with 2 red balls and 2 blue balls, we need to consider the number of ways to choose 2 red balls from the 4 available red balls and the number of ways to choose 2 blue balls from the 4 available blue balls.

These are both combinations, and we can use the formula for combinations to calculate them:

C(n, k) = n! / (k! (n-k)!).

For the red balls, C(4, 2) = 4! / (2! (4-2)!) = 6.

For the blue balls, C(4, 2) = 4! / (2! (4-2)!) = 6.

The total number of arrangements of 6 balls with 2 red balls and 2 blue balls is the product of the number of arrangements for each type of ball:

C(4, 2) * C(4, 2) = 6 * 6 = 36

a. Adding the same number to two numbers produces the same result. Example: 4 + 3 = 7, 7 + 3 = 10, b. Commutative Property: Order does not matter. Example: 4 + 7 = 7 + 4.

The Density Property of Real Numbers states that between any two real numbers, there are an infinite number of other real numbers. This means that for any two real numbers, no matter how close or far apart they are, there is always a third number between them. An example of this property would be if we have two numbers, 4 and 7. If we add 3 to each of these numbers, we will get the same result. 4 + 3 = 7, and 7 + 3 = 10. This shows that no matter what two real numbers we pick, there will always be a third number between them, and when we add the same number to both of them, we will get the same result. Another property of numbers is the Commutative Property, which states that the order of the numbers doesn’t matter when performing certain operations. For example, when adding two numbers, 4 + 7 = 7 + 4. This means that it doesn’t matter which number comes first when adding. This property applies to other operations as well, such as multiplication, division, and subtraction.

The circumference of the circle is 2π x 2, or 12.57 units.

To find the circumference of a circle, we use the formula C = 2πr, where C is the circumference, π is a constant value of 3.14, and r is the radius of the circle. In this case, the radius of the circle is 2 units. So, we plug the values into the formula and get 2π x 2 = 12.57 units. This means that the circumference of the circle is 12.57 units. To put it another way, the circumference is equal to the diameter of the circle (2 units) multiplied by the value of pi (3.14). Therefore, the circumference of a circle with a radius of 2 units is 12.57 units.

Answer:

Option 4
y = 2x + 3

Step-by-step explanation:

Equation of a line in slope intercept form is
y = mx + b
where m = slope and b = y-intercept

Slope m = rise/run = Δy/Δx with Δy = change in y values between any two points on the line and Δx = corresponding change in x values

b is the y-intercept, value of y when x = 0 and indicates the point at which the line crosses the y-axis

Let's take two distinguishable integer points on the line

(0, 3) and (1, 5) are two points

rise = Δy = 5 - 3 = 2
run = Δx = 1 - 0 = 1

So slope = 2/1 = 2

Since y = 3 at x = 0, y-intercept b = 3

Equation of line is
y = 2x + 3

The number of teeth a hacksaw blade should have to cut off a piece of aluminum from 1'' square bar depends on the thickness of the aluminum bar.

2. Generally, a hacksaw blade with 18 teeth per inch is used to cut off aluminum from 1'' square bar.

For example, if the aluminum bar being cut is thin (1/8'' or less) then a hacksaw blade with 18 teeth per inch should be used. On the other hand, if the aluminum bar is thicker (greater than 1/8''), then a hacksaw blade with fewer teeth per inch should be used.

Answer:

Let's call the travel fee "t" and the hourly fee "h". Then the total cost of a repair, y, can be represented as:

y = t + hx

We can use the two given pieces of information to write two equations and solve for t and h:

2h + t = 100

6h + t = 260

Subtracting the first equation from the second, we get:

4h = 160

Dividing both sides by 4, we get:

h = 40

Substituting this value of h back into the first equation, we get:

2h + t = 100

2(40) + t = 100

80 + t = 100

Subtracting 80 from both sides, we get:
