1. Write 306,000,004,210 in words.​

Answer:

Slope of the given line=-5

Slope of the perpendicular line=1/5 [reciprocal with opposite sign]

Required equation is (y+4)=1/5(x+5)

5y+20=x+5

x-5y=15

Without using slope

Equation of the given line is 5x+y=3

Equation of the perpendicular line is x-5y=k [interchange the coefficient of x and y

and put opposite sign for y and equating the equation to k]

This line passes through (-5,-4)

-5+20=k therefore k=15

The required equation is x-5y=15

Answer:

The answer would be 43 because 62.25-18.92=43.34 therefore it would be rounded down the nearest whole number

Answer:

A

Step-by-step explanation:

First round both numbers to the nearest whole number which would be 62-19. Now calculate. The answer is 43

Answer:

x = 5

Step-by-step explanation:

Given that B is at the midpoint of AC, then

AB = BC ← substitute values

3x + 8 = 5x - 2 ( subtract 5x from both sides )

- 2x + 8 = - 2 ( subtract 8 from both sides )

- 2x = - 10 ( divide both sides by - 2 )

x = 5

Answer: 5.9

Step-by-step explanation: You want to round up so since the 7 is greater than 5 you move the second digit up. So 5.9

Step-by-step explanation:

one thing to be noteworthy is that this triangle has two angles, a 60° one and a 90° one, meaning the last angle will be a 30° one, thus we can use the 30-60-90 rule.

Check the picture below.

In mental math, we simplify computations. For the given problem, we round 6,189 to 6,000, subtract it from 56,211 to get 50,211 and add back the amount we rounded down (189) to get the answer 50,400.

Using mental math means finding a solution with simplified steps or approximate computation, instead of the traditional written or calculator methods.

In this problem; 56,211 - 6,189, you can use rounding to make this easier.

1. Round 6,189 to the nearest thousand, which is 6,000.

2. Subtract this from 56,211 to get 50,211.

3. However, we rounded down by 189 at the beginning. To correct this, just add 189 back to the answer, resulting in 50,400.

This method simplifies the process and lessens your risk of making errors when handling larger numbers.

For 56,211 - 6,189, rounding gives 50,000, and adding the small differences back in results in a final answer of 50,022.

To use mental math for the subtraction 56,211 - 6,189, consider the following steps:

First, round each number to the nearest thousand to simplify: 56,211 rounds to 56,000 and 6,189 rounds to 6,000.

Subtract the rounded numbers: 56,000 - 6,000 = 50,000.

Note that the actual numbers are slightly higher than their rounded values, making the difference slightly more than 50,000.

Adjust the result by calculating the exact difference between the small parts ignored during rounding. For example, the difference between 56,211 and 56,000 is 211, and

the difference between 6,189 and 6,000 is 189.

Add the small differences back into the result: 211 - 189 = 22.

Combine the simple difference with the adjustment: 50,000 + 22 = 50,022.

Therefore the final answer is  50,022

Answer:

1/(x + 1)

Step-by-step explanation:

1/(x² + 3)

x = √(x - 2)

1/((√(x - 2))² + 3

1/(x - 2 + 3)

1/(x + 1)

2lbs/28oz

Divide each side by 2

1lbs/14oz

The simplest form of the ratio is: 8/7. To express the ratio of 2 pounds to 28 ounces as a fraction in simplest form, we need to convert both quantities to the same unit of measurement.

Since there are 16 ounces in 1 pound, we can convert 2 pounds to ounces:

2 pounds * 16 ounces/pound = 32 ounces

Now, the ratio becomes:

32 ounces to 28 ounces

To write this ratio as a fraction in simplest form, we can divide both numbers by their greatest common divisor (GCD), which is 4 in this case:

32 ounces ÷ 4 = 8

28 ounces ÷ 4 = 7

So, the simplest form of the ratio is:

8/7

Answer: A

Step-by-step explanation: You know multiplying will be involved, so B can automatically be removed. It states that the length is 8 cm longer. You know absolutely nothing about the width, so the variable of w can be given for the width. You also know the length will be 8 cm longer, of w+8. w and w+8 will be multiplied, which gives you w(w+8).

la respuesta es A. 3x - 3

Final answer:

To find (f - g)(x), subtract the function g(x) from f(x). (f - g)(x) = 3x - 3.

Explanation:

To find (f - g)(x), we need to subtract the function g(x) from f(x).

f(x) = 5x - 2

g(x) = 2x + 1

Subtracting g(x) from f(x) gives us:

(f - g)(x) = (5x - 2) - (2x + 1)

Expanding the expression:

(f - g)(x) = 5x - 2 - 2x - 1

Combining like terms:

(f - g)(x) = 3x - 3

Step-by-step explanation:

so what squared is 100?

10. but also -10.

10*10 = 100, and -10*-10 is also 100.

therefore, sqrt(100) has two solutions, which are positive or negative 10, and that's the application of ±.

Answer:

10

Step-by-step explanation:

Factor the number: 100 = [tex]10^{2}[/tex]

=[tex]\sqrt{10^2}[/tex]

Apply radical rule: [tex]\sqrt[n]{a^n} =a[/tex]

[tex]\sqrt{10^2} =10[/tex]

The three zeros in the product of 6 and 10^3 arise from the properties of multiplication and exponents; 10^3 results in 1000, which when multiplied by 6, gives 6000, featuring three zeros.

The reason there are three zeros in the product of 6 and 10^3 is due to the properties of multiplication and exponents. In exponentiation, 10^3 means multiplying 10 by itself three times, which gives the result of 1000. When you multiply 6 by 1000 (the result of 10^3), it gives 6000, which has three zeros. The number of zeros in the product corresponds to the power of 10 in the original expression.

Answer: {5, 3, 1, -1}

Step-by-step explanation:

So, domain is the x-values and range is the y-values. You're trying to find the y-values. The problem gives you the domain: {0, 1, 2, 3}. So now you plug in the x values into the equation to get the y-values.

1.    y = 5 - 2(0)

        y = 5

2.    y = 5 - 2(1)

      y = 3

3.    y = 5 - 2(2)

      y = 1

4.    y = 5 - 2(3)

      y = -1

So, now you have the y-values, or range.

{5, 3, 1, -1}
