juan needs to measure 6 cups of flour for a recipe.he only has a 1/4 cup measuring cup.how many times must he fill the measuring cup to get 6 cups of flour

Answers

Answer:

Juan would need to fill up the 1/4 measuring cup 24 times.

Step-by-step explanation:

So to measure one cup of flour with a 1/4 measuring cup, you would need to fill up the 1/4 measuring cup 4 times. Since we want 6 cups, you would need to fill up the 1/4 measuring cup 24 times. 6 times 4 = 24. Hope this helps!

Final answer:

Juan would need to use his 1/4 cup measuring cup 24 times to get a total of 6 cups of flour. This is solved by multiplying the number of quarters (4) in a cup with the total cups Juan needs (6).

Explanation:

In order to understand the problem, we need to consider that each cup contains 4 quarters. So, if 1 cup equals 4 quarters, then 6 cups, the amount Juan needs for his recipe, would be 6 multiplied by 4, which is 24. Therefore, Juan would need to fill his 1/4 cup measuring cup 24 times to get a total of 6 cups of flour.

Solve for x to the nearest degree (34.3 = 34)

Answers

Answer:

48°

Step-by-step explanation:

We can solve this using our knowledge on tangents of an angle. Remember, tangents are the opposite leg divided by the leg adjacent to that angle.

This means the tangent of x° =  [tex]\frac{10}{9}[/tex]. Now that we know the tangent ratio, we can find the angle with inverse trigonometric ratios. These kinds of ratios give us the opposite of the tangent - which would lead to the angle measure we're looking for. The equation would look like this:

[tex]x = arctan (\frac{10}{9})[/tex]

Using a calculator, the answer would be:

[tex]x = 48.0128[/tex]

Rounding this to the nearest degree would give us 48° as our answer! I hope this was clear enough.

Answers

Final answer:

The solution to the system of linear equations represented by D and Dx is (x,y,z) = (5, 4, -11), which corresponds to option A.

Explanation:

To solve for Dx in the given system of linear equations, we multiply matrix D by the unknowns (x, y, z). So let's assume that Dx = (x, y, z).

By comparing the results of Dx and the given matrix, we can write the system of equations as:

1x + 2y - 3z = 46; 2x - 6y + z = -41; 4x + 2y + 5z = -11.

By solving this system of equations, we can find that the solution is (x,y,z) = (5, 4, -11), which corresponds to the multiple-choice option A.

To find the solution of the system of linear equations represented by matrices D and Dx, we need to solve the equation Dx = Dⁿⁿ. By calculating the inverse of matrix D and substituting the values of Dx, we find that the solution is (5, 7, -9).

Explanation:

To find the solution of the system of linear equations represented by matrices D and Dx, we need to solve the equation Dx = Dⁿⁿ

Let's use matrix inversion to solve for x. We know that Dx = Dⁿⁿ can be rewritten as x = Dⁿⁿ −1 Dx. To find Dⁿⁿ −1, we need to calculate the inverse of matrix D:

After calculating the inverse of matrix D, we can substitute the values of Dx into the equation x = Dⁿⁿ −1 Dx to find the solution.

Plugging in the values of Dⁿⁿ and Dx, we get x = (5, 7, -9).

Answers

Answer:

57.8  and 32.2 degrees

Step-by-step explanation:

Complementary angles = 90 degrees

90-57.8= 32.2

The answer is 32.2 because a right angle would equal 90 and complementary angles equal 90. So 90 minus 57.8 equals 32.2

Use the definition of continuity and the properties of limits to show that the function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3

Answers

Answer:

See below.

Step-by-step explanation:

First check that f(x) has a real value at x = 3:

f(3) = 3^2 + 5(3 - 2)^7

=  9 + 5 * 1^7

=  14,

So the first condition is met.

Now we check if limit as x approaches 3 exists.

As x approaches 3 from below f(x) approaches 14 and at x = 3 = 14.

As x approaches 3 from above f(x) approaches 14 and at x = 3 = 14.

These 3 conditions  shows that f(x) is continuous at x = 3.

Final answer:

The function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3 because it meets all the conditions of continuity: it is defined at x = 3, the limit of the function as x approaches 3 exists, and the limit equals the function's value at x = 3.

Explanation:

The function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3 if it satisfies the following three properties: the function is defined at x = 3, the limit of the function as x approaches 3 exists, and the function value at x = 3 is equal to the limit as x approaches 3.

Step 1

The function is defined at x = 3. When we substitute x = 3, we get f(x) = 3^2 + 5(3 - 2)^7= 9 + 5*1^7 = 14.

Step 2

The limit of the function as x approaches 3 exists. As x approaches 3 from both the left and right sides, the function takes the value 14.

Step 3

Finally, the limit as x approaches 3 is equal to the function's value at x = 3. In other words, the limit is 14, which is equal to the function's value when x = 3 (which is also 14).

Since the function satisfies all these conditions, we can say that the function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3.

Step-by-step explanation:

Final answer:

The radius of a circle can be found using the formula r = C/(2π), where r is the radius and C is the circumference of the circle.

Explanation:

The radius of a circle can be found using the formula r = C/(2π), where r is the radius and C is the circumference of the circle. Since the value of π is approximately 3.14159, you can divide the circumference of the circle by 2π to find the radius.

For example, if the circumference of the circle is 10 units, the radius would be 10/(2π) units.

Remember to use the appropriate units for both the circumference and the radius.

Mr. Hopkins has a 1-meter wire he is using to make clocks. Each fourth meter is marked off and

divided into 5 smaller equal lengths. If Mr. Hopkins bends the wire at - meter, what fraction of the

smaller marks is that?

Answers

Answer: fraction = 1/20 or 0.05

Step-by-step explanation:

Let's first convert metre to centimeter

1 metre = 100 centimeters

Given that Each fourth meter is marked off and divided into 5 smaller equal lengths. This means:

1/4 × 100 = 25

Then divide 25 into 5 places

25/5 = 5cm

If Mr. Hopkins bends the wire at - meter, what fraction of the smaller marks is that?

The fraction = 5/100 = 1/ 20 or 0.05

Using the Addition Method, solve for y in the following system of linear equations.

4x-2y=6
2x+y=7

Answers

Answer:

x = 3.33

y = 0.33

Step-by-step explanation:

to evaluate for y in this system of linear equation we would say that let

4x-2y=6 ........................................................... equation 1

2x+y=7 ..............................................................equation 2

from equation 2

2x+y=7 ..............................................................equation 2

y = 7 - 2x........................................... equation 3

substitute for y in equation 1

4x-2y=6 ........................................................... equation 1

4x -2( 7 - 2x) = 6

4x - 14 + 2x = 6

6x = 6 +14

6x = 20

divide both sides by 6

6x/6 = 20/6

x = 3.33

put x into equation 3

y = 7 - 2x........................................... equation 3

y = 7 -2( 3.33)

y = 7 -6.667

y = 0.33

Final answer:

To solve for y using the Addition Method, first manipulate the equations to have opposite coefficients for y, add them to find x, and then substitute x back into one of the original equations to solve for y. The solution is x = 2.5 and y = 2.

Explanation:

The student is asking how to solve for y in a system of linear equations using the Addition Method. The given system of equations is:

4x - 2y = 6

2x + y = 7

To use the Addition Method, we aim to eliminate one variable by adding the equations. First, we manipulate the equations to have opposite coefficients for the y variable. Multiply the second equation by 2:

(2x + y) × 2 → 4x + 2y = 14

Now we have:

4x - 2y = 6  (Equation A)

4x + 2y = 14 (Equation B)

Add Equation A and Equation B:

4x - 2y + 4x + 2y = 6 + 14

8x = 20

x = 20 / 8

x = 2.5

Substitute x back into the second original equation to solve for y:

2(2.5) + y = 7

5 + y = 7

y = 7 - 5

y = 2

Hence, the solution to the system of equations is x = 2.5 and y = 2.

Then you use 8, which means you have to find two numbers that add up to 26, and are factors of 20, which could be nothing, there aren't any.

Last you do 27 which means you need to find two numbers that add up to 9 and are factors of 27, which can be 4 and 5, because 4+5=9 and 4*5=20.
