Step-by-step explanation:

The difference in mass between Earth and Venus is 1.10 times 10²⁴ kg.

The question asks for the difference in mass between Venus and Earth. To find this, we subtract the mass of Venus from the mass of Earth. The calculation goes as follows:

Mass of Earth = 5.97 times 10²⁴ kg

Mass of Venus = 4.87 times 10²⁴ kg

Difference = Mass of Earth - Mass of Venus

Difference = (5.97 times 10²⁴) - (4.87 times 10²⁴) = 1.10 times 10²⁴ kg

So, the difference in mass between Earth and Venus is 1.10 times 10²⁴ kg.

Answer:

Step-by-step explanation:

12x-20=6(x-20)-9x

Opening bracket

12x - 20 = 6x - 120 - 9x

Collecting like terms

12x - 6x + 9x = -120 + 20

15x = -100

Dividing by 15

15x/15 = -100/15

x = -20/3

x = - 6 2/3

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

12x - 20 = 6( x - 20) - 9x

pay attention to the brackets as you simplify.

Let's work on it:

12x - 20 = 6x - 120 -9x

Collecting like terms to further simplify the equation.

12x - 6x + 9x = -120 + 20

15x = -100

Let's make x the subject formula by dividing through by 15

Therefore:

x = -100 / 15

Divide through by 5

x = -20 / 3

Since nothing can easily divide through, we turn it to a mixed fraction

x = - 6 2/3

( Minus six whole number, two divided by three)

The correct answer is that 55 squares on a 10-by-10 grid would be shaded to represent 55%.

To solve this problem, we need to calculate the total number of squares on a 10-by-10 grid and then determine what 55% of that total would be.

First, we calculate the total number of squares on the grid:

[tex]\[ \text{Total squares} = 10 \times 10 \\\[ \text{Total squares}= 100 \][/tex]

Next, we find 55% of the total number of squares:

[tex]\[ \text{Number of shaded squares} = \frac{55}{100} \times 100 \][/tex]

[tex]\[ \text{Number of shaded squares} = 55 \][/tex]

So, to represent 55% on a 10-by-10 grid, we would shade 55 out of the 100 squares.

Option A

The vertex is (h, k) = (5, -25)

Solution:

Given function is:

[tex]f(x) = x^2-10x[/tex]

The vertex form is given as:

[tex]y = a(x-h)^2+k[/tex]

Rewrite the equation in vertex form

[tex]f(x) = x^2-10x[/tex]

Complete the square for  [tex]x^2-10x[/tex]

Use the form [tex]ax^2+bx+c[/tex] to find the values of  a, b, c

a = 1 , b = -10, c = 0

Consider the vertex form of a parabola

[tex]a(x+d)^2+e[/tex]

Substitute the values of a and b into the following formula to find "d" :

[tex]d = \frac{b}{2a}\\\\d = \frac{-10}{2 \times 1}\\\\d = -5[/tex]

Find the value of "e" using the formula,

[tex]e = c - \frac{b^2}{4a}\\\\e = 0 - \frac{(-10)^2}{4 \times 1}\\\\e = -25[/tex]

Substitute the value of a, d, e into vertex form

[tex]a(x+d)^2+e\\\\1(x-5)^2-25\\\\(x-5)^2-25[/tex]

Set y equal to above equation

[tex]y = (x-5)^2-25[/tex]

Compare the above equation with vertex form

[tex]y = a(x-h)^2+k[/tex]

[tex]y = (x-5)^2-25[/tex]

We find, h = 5 and k = -25

Thus the vertex is (h, k) = (5, -25)

Answer:

70° and 20°

Step-by-step explanation:

let x be the measure of one angle then x + 50 is the measure of the other angle, thus

x + 50 + x = 90

2x + 50 = 90 ( subtract 50 from both sides )

2x = 40 ( divide both sides by 2 )

x = 20

The smallest angle is 20° and the other angle is 20 + 50 = 70°

Answer:x f(x)=0.5x g(x)=−0.5x+1

This implies that f(x)= 0.5 and

g(x)= -0.5x + 1

-0.5x + 1= 0.5

-0.5x= 0.5-1

-0.5x=-0.5

x= -0.5/-0.5

x=1

Step-by-step explanation:

Final answer:

To solve f(x) = g(x), set 0.5x equal to −0.5x + 1. Solve for x by combining like terms, which gives x = 1 as the solution.

Explanation:

To determine the solution to f(x) = g(x), we set the two functions equal to each other and solve for x.

The function f(x) is given by f(x) = 0.5x, and the function g(x) is given by g(x) = −0.5x + 1.

Setting f(x) equal to g(x), we have:
0.5x = −0.5x + 1

To solve for x, we'll combine like terms by adding 0.5x to both sides, which gives us:
0.5x + 0.5x = 11x = 1

When we divide both sides by 1, we get:

x = 1

So the solution to f(x) = g(x) is when x = 1.

To find the distance from a point to a line, we can use the distance formula. For this problem, the distance from point A(-2,3) to the line y=1/2x+1 is approximately 2.5 units.

To find the distance from a point to a line, we can use the formula for the distance between a point and a line. The formula is:

d = |Ax + By + C| / √(A^2 + B^2)

In this case, the equation of the line is y = (1/2)x + 1, which can be rewritten as 2x - y + 2 = 0. Plugging in the coordinates of point A in the equation, we get:

d = |(2 * -2) + (-1 * 3) + 2| / √((2^2) + (-1^2)))

After completing the calculation, rounding the answer to the nearest tenth, the distance from point A(-2,3) to the line y = (1/2)x + 1 is approximately 2.5 units.

Answer:

A) 100000

B) 80/100000

Step-by-step explanation:

A) it is a simple matter of multiplying the possibilities of the digit it could be to the second one then to the third and so on and so forth

B) if a person were to enter a 5 digit code at random say it be 00000 then that person would have 80 out of a 100000 chance of unlocking the door as there are only 80 access codes that are correct

There are 100,000 possible 5-digit codes. The probability of a random 5-digit code granting access is 0.0008 or 0.08%.

This problem involves combinatorics and probability.

a) If each digit of the 5-digit code can be any number from 0-9, then for each digit, 10 possibilities exist. Hence the total number of possibilities for a 5-digit code would be 10*10*10*10*10, which is 100,000. So there are 100,000 possible 5-digit codes.

b) Probability is defined as the number of ways an event can occur over the total number of outcomes. If each 5-digit code is unique and assigned to only one employee, with 80 employees, there are 80 valid codes. Therefore, the probability of someone entering a 5-digit code at random and gaining entry would be 80 (the number of successful outcomes) divided by 100,000 (the total number of possible outcomes), which is 0.0008 or 0.08%.

Answer: Second option.

Step-by-step explanation:

Given the following Inequality provided in the exercise:

[tex]50 - 8m \geq 0[/tex]

You need to solve for "m".

Then, you can follow the steps below in order to find the solution of the inequality:

Step 1: You must apply the Subtractrion property of Inequality and subtract 50 from both sides:

[tex]50 - 8m-(50) \geq 0-(50)\\\\- 8m \geq -50[/tex]

Step 2: Now you need to apply the Division property of Inequality and divide both sides of this inequality by -8 (Since you are dividing both sides by a negative number the direction of the inequality changes). Then, you get:

[tex]\frac{- 8m}{-8} \geq \frac{-50}{-8}\\\\m\leq \frac{25}{4}\\\\m\leq6.25[/tex]

To prove that LMN~XYZ by the SSS similarly theorem , the measure of sides are LM is 4 units and XZ is 6 units

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ΔLMN

Let the second triangle be ΔXYZ

Answer:

x = 72

Step-by-step explanation:

To solve for 'x', isolate it. This means to keep 'x' on one side of the equal sign, while moving the other numbers to the other side. The numbers on the other side will tell you what 'x' equals to.

When 'moving' a number to the other side, you cancel it out where it originally is by doing reverse operations. (Reverse operation pairs are addition/subtraction and division/multiplication). To keep an equation balanced, what you do to one side you have to do to the other.

[tex]\frac{3}{8}x-17=10[/tex]        Keep 'x' on the left and move everything over.

[tex]\frac{3}{8}x-17+17=10+17[/tex]        Add 17 to both sides. "-17" cancels out on the left.

[tex]\frac{3}{8}x=27[/tex]        Simplified right side

[tex]\frac{3}{8}x/\frac{3}{8}=27/\frac{3}{8}[/tex]        Because 3/8 originally multiplies with 'x', do the reverse: divide both sides by 3/8.

[tex]x=27/\frac{3}{8}[/tex]        To divide a fraction, change to multiplication and flip the fraction's top and bottom numbers.

[tex]x=27*\frac{8}{3}[/tex]        Combine the factors into one fraction.

[tex]x=\frac{27*8}{3}[/tex]        Multiply 27 by 8 in the numerator.

[tex]x=\frac{216}{3}[/tex]        Simplify the fraction by dividing top by bottom.
