It depends on the thickness of the aluminum bar. Generally, a hacksaw blade with 18 teeth per inch is used to cut off aluminum from 1'' square bar.

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. The fewer teeth per inch the hacksaw blade has, the thicker the aluminum bar it can cut through. It is important to choose the correct hacksaw blade for the job in order to ensure a clean and safe cut.

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:

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 ratio of votes for candidate B compared to candidate A is 1.3:1

What is Ratio?

A ratio in mathematics illustrates how many times one number contains another.

If there were a total of 64 votes and 28 votes went to candidate A, then the number of votes for candidate B can be found by subtracting the votes for candidate A from the total number of votes:

64 - 28 = 36

So, candidate B received 36 votes.

To find the ratio of votes for candidate B compared to candidate A, we divide the number of votes for candidate B by the number of votes for candidate A:

36 / 28 = 1.3

Therefore, The ratio of votes for candidate B compared to candidate A is 1.3:1

Answer:

Why? I subtract the numbers. How to do that is by looking at the table. You always use two ordered pairs. Let's choose (-3,12) and (-2,8).

Step 1: Choose two ordered pairs (you can choose any two, it doesn't matter).

Now, subtract the y's together and subtract that x's together. So, what is 12-8? That's obvious, it's 4. Alright, how about -3-(-2)? Well, two negatives make a positive, so the problem is actually -3+2. So, what's that? Correct, -1. And, since slope is y/x, the answer would be -4/1, or -4.

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 length and the width of the playground 12 yards and 17 yards respectively.

As per the data given in the question the area of the playground is 204 square yards.

Area = 204 square yards.

The width of the playground is 5 yards longer than its length.

Let the length of the playground be 'l' yards.

Then the width of the playground will be (l + 5) yards.

The formula for the area of the playground is Length × Width.

A = Length × Width

204 = l (l + 5)

204 = [tex]l^{2}[/tex] + 5l

[tex]l^{2}[/tex] + 5l - 204 = 0

[tex]l^{2}[/tex] + 17l - 12l - 204 = 0

l (l + 17) -12 (l + 17) = 0

(l + 17) (l - 12) = 0

(l + 17) = 0 or (l - 12) = 0

l = -17 or l = 12

Length cannot be the negative value.

So the value of the length is 12 yards.

Then width = l + 5

Width = 12 + 5

Width = 17 yards

Therefore length is 12 yards and width is 17 yards.

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

Option 4)

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:

t = 20

So the total cost of a repair, y, as a function of the number of hours spent fixing a leak, x, can be represented as:

y = 20 + 40x

What is square?

Having four equal sides, a square is a quadrilateral. There are numerous square-shaped objects in our immediate environment. Each square form may be recognised by its equal sides and 90° inner angles. A square is a closed form with four equal sides and interior angles that are both 90 degrees. Numerous different qualities can be found in a square.

area of the garden = 4a  ( a = side )

= 4(18)

= 72m

length of wire required to fence three rounds = 3 × perimeter

Two sides out of three of this triangle are equal to each other, therefore this is an isosceles triangle

Let x° = ∠B° = ∠C°

Sum of interior angles of a triangle = 180°

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:

The maximum number of functions that can be called when calling the checkweather function depends on the program. If the program contains other functions, then up to three functions can be called, including the checkweather function. When calling the checkweather function, the first function that will be called is the checkweather function itself. After the checkweather function is called, the program will then proceed to call any other functions that have been determined by the program.
