What is 0.16666666666 as a simplified fraction

It will take approximately 6.24 minutes for both faucets to fill the bathtub when used simultaneously.

To solve this problem, we need to find the combined rate at which both faucets can fill the bathtub. The hot water faucet can fill the tub in 13 minutes, and the cold water faucet can fill it in 12 minutes. We can express their rates as fractions of the tub they can fill per minute as 1/13 and 1/12, respectively.

When we add these rates together, we get the combined rate:

Rate of hot water faucet + Rate of cold water faucet = combined rate

1/13 + 1/12 = (12 + 13) / (13  imes 12) = 25 / 156

The combined rate is 25/156 tubs per minute. To find out how long it will take for both faucets to fill the tub together, we take the reciprocal of the combined rate:

Time to fill the tub = 1 / (combined rate) = 156 / 25 = 6.24 minutes

Therefore, it will take approximately 6.24 minutes for both faucets to fill the bathtub when used simultaneously.

Final answer:

Algebraically, the relation y = x^3 - 4x is not symmetric to the x-axis or y-axis but is symmetric with respect to the origin when both x and y are replaced with their negatives.

Explanation:

To determine if the relation y = x3 − 4x is symmetric with respect to the x-axis, y-axis, or the origin, we perform a series of tests substituting -x for x (to test y-axis symmetry), -y for y (to test x-axis symmetry), and both -x for x and -y for y (to test origin symmetry).

Y-axis symmetry test:

Replace x with -x:

y = (-x)3 - 4(-x)

y = -x3 + 4x ≠ x3 − 4x (not symmetric to y-axis)

X-axis symmetry test:

Replace y with -y:

-y = x3 - 4x ⇒ y = -x3 + 4x ≠ x3 − 4x (not symmetric to x-axis)

Origin symmetry test:

Replace both x with -x and y with -y:

-y = (-x)3 - 4(-x)

-y = -x3 + 4x

y = x3 − 4x (symmetric to origin)

Answer:

Option B. is the correct option.

Step-by-step explanation:

The circular base of a cone has a radius of 5 cm. The height of the cone is 12 cm. Slant height of the cone is 13 cm.

We have to calculate the approximate surface area of the cone.

Since we know Surface area of a cone = Area of circular base + lateral area of the cone

Now Surface area of a cone = πr² + πrl = πr(r + l)

By putting the values of the dimensions of a cone in the formula.

S.A. = π (5² + 5×13) = 3.14×(25 + 65) = 3.14×(90) = 282.60 ≈ 283 cm²

Therefore, Option B is the correct option.

The given equation resulting in one solution, which is z = 1/9.

To find the number of solutions to the equation -2 + 10 + 7z = 16z + 7, we first simplify and solve for z. Start by combining like terms on the left side:

-2 + 10 = 8, so the equation becomes 8 + 7z = 16z + 7.

Next, we get all the terms with z on one side and the constants on the other:

Subtract 7z from both sides:

8 = 16z - 7z + 7

Combine z terms:

8 = 9z + 7

Subtract 7 from both sides:

1 = 9z

Divide both sides by 9:

z = 1/9

12 *4 = 48 total miles in 50 minutes

48 / 50/60 =  57.6 miles per hour

In the situation, x + (-x) is combined making zero and other y + (-y) is making zero.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.

Summation = addition of two or more numbers or variable

Subtraction = Minus of any two or more numbers with each other called subtraction.

Division = divide any two numbers or variable called division.

Multiplication = to multiply any two or more numbers or variables called multiplication.

If we combine any two opposite quantities then their summation must be zero.

For example,

if you combine 5 and -5 then it will be 0.

If you combine 10 and -10 then it will be 0.

So,

The first situation ⇒

Combining x and -x

x + (-x) = 0

The second situation ⇒

Combining y and -y

y + (-y) = 0

Hence, In the situation, x + (-x) is combined making zero and other y + (-y) makes zero.

The factorization of 49b² - 81 using the difference of squares formula is (7b - 9)(7b + 9).

The question is asking to factorize the expression 49b² - 81, which is a difference of two squares. The difference of squares formula is a² - b² = (a - b)(a + b). In your question, a² is 49b² and b² is 81. Therefore, a would be 7b (since square root of 49b² is 7b) and b would be 9 (since square root of 81 is 9).

Thus, using the formula, the factorization of 49b² - 81 will be (7b - 9)(7b + 9). This provides an explanation of the concepts involved and the steps followed in the solution.

Answer:

Step-by-step explanation:

We know that the 1st equation + 2nd equation + 3rd equation = 45.  Now we just need to identify from the infor given what these equations are, then set them to equal 45.

It has already been determined that the 1st equation is x.

The second equation is "3 more than twice the first".  Twice the first is 2x, and 3 more is +3; therefore, the second equation is: 2x + 3.

The third equation is "2 more than the first".  2 more than is +2, so the third equation is x + 2.

Now we have all 3:

1st:  x

2nd:  2x + 3

3rd:  x + 2

Add them all up and set them equal to 45:

x + 2x + 3 + x + 2 = 45.

You don't have choices listed, so it's either that one above, or simplified down to:

4x + 5 = 45

After that, any simplification done will be solving the equation.

To vertically subtract 30.06 from 100.6, start by borrowing 1 from the tens place and adding it to the ones place. Then, borrow 10 from the hundreds place and add it to the tens place. Finally, combine the result to get 70.54.

To vertically subtract 30.06 from 100.6, you'll need to line up the decimal points vertically. Start by subtracting the hundredths place (0.06) from the hundredths place (0.00). Since 6 is bigger than 0, you'll need to regroup. Borrow 1 from the tens place by making it 9, and add it to the ones place, making it 10. Then, you can subtract 6 from 10, which gives you 4. Next, subtract the whole number part (30) from the whole number part (100). Since 0 is smaller than 3, regroup again by borrowing 10 from the hundreds place and adding it to the tens place, making it 20. Then, subtract 3 from 10, which gives you 7. Finally, combine the result by placing the decimal point in the correct position, which gives you the answer: 70.54.
