Answer:

10^7

Step-by-step explanation:

So we would start with 10 and a trick to help you is when your turning a number with 10 at the start with each number you raise it by is how many 0 it will have behind it for example 10,000,000 would be 10^7 cause you have 0 zeros in it.

10,000,000 in exponent form is 10⁷. Therefore, 20,000,000 can be written as 2 × 10⁷. This provides a concise mathematical way of expressing large numbers.

To write 10,000,000 using exponents, we recognize that this number is a power of 10. Specifically, 10,000,000 can be written as 10 to the power of 7. This is because:

10,000,000 = 10⁷

When you multiply 10 by itself 7 times (10 × 10 × 10 × 10 × 10 × 10 × 10), you get 10 million. Therefore, the population of Australia, which is more than 20,000,000 people, can be written as:

20,000,000 = 2 × 10,000,000 = 2 × 10⁷

Answer:

3 min 42 seconds

Step-by-step explanation:

1 minute=60 seconds so 7 minutes = 420 seconds. Plus the other 24 is 444 seconds. 444/2=222 so its 222 seconds or 3 minutes and 42 seconds

7 min = 7 x 60 sec = 420 sec

420 sec + 24 sec = 444 sec

444sec : 2 = 222 sec

222 sec = 3x60sec + 42sec = 3 min 42 sec

Step-by-step explanation:

The sizes of the angles are 34° , 44° , 102°

Step-by-step explanation:

The given is:

We need to find the size of each angle in the triangle

∵ The size of the smallest angle = x°

∵ The size of the largest angle is 3 times the size of the smallest angle

∴ The size of the largest angle = x × 3 = (3x)°

∵ The third angle is 10° more than the smallest angle

∴ The size of the third angle = (x + 10)°

Add the size of the three angles and equate the sum by 180°

∵ The sum of the sizes of the interior angles of a Δ is 180°

∴ x + (3x) + (x + 10) = 180

∴ x + 3x + x + 10 = 180

- Add like terms

∴ 5x + 10 = 180

- Subtract 10 from both sides

∴ 5x = 170

- Divide both sides by 5

∴ x = 34

∵ x is the size of the smallest angle

∴ The size of the smallest angle is 34°

∵ 3x is the size of the largest angle

∴ The size of the largest angle = 3(34) = 102°

∵ x + 10 is the size of the third angle

∴ The size of the third angle = 34 + 10 = 44°

The sizes of the angles are 34° , 44° , 102°

Answer:

7,920,000

Step-by-step explanation:

The question is asking the number of times that 4 inches fits in 500 miles. We need to divide 500 miles by 4 inches, but first we need to convert 500 miles into inches.

12 inches = 1 foot

5280 ft = 1 mile

500 miles * (5280 ft)/(1 mile) * (12 in.)/(1 ft) = 31,680,000 inches

Now that we know that 500 miles is the same as 31,680,000 inches, we divide that number of inches by 4 inches.

(31,680,000 inches)/(4 inches) = 7,920,000

Considering the definition of probability, the probability that the family visits the museum or rides the ferry is 81%.

Definition of Probabitity

Probability  is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.

Union of events

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

where the intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A∩B is verified when A and B occur simultaneously.

Events and probability in this case

Let A be the event that a family visits the City Museum, and B be the event that a family rides the Three Rivers Ferry. The given probabilities are:

P(A)= 0.46

P(B)= 0.47

P(A and B)= P(A∩B)= 0.12

In this case, considering the definition of union of eventes, the probability that a course has a final exam or a research project is calculated as:

P(A∪B)= P(A) + P(B) -P(A∩B)

P(A∪B)= 0.46  + 0.47 -0.32

P(F∪R)= 0.81= 81%

Finally, the probability that the family visits the museum or rides the ferry is 81%.

Answer:

[tex]f(x)=x^3-7x-6[/tex]

Step-by-step explanation:

If x = 3 is a root of a polynomial f(x), then x - 3 is a factor of this polynomial.

If x = -2 is a zero of a polynomial function f(x), then f(-2) = 0 and x - (-2) = x + 2 is a factor of f(x).

If x = -1 is an x-intercept of the function, then y = 0 and x - (-1) = x + 1 is also a factor of the function f(x).

Therefore, the polynomial expression is

[tex]f(x)=(x-3)(x+2)(x+1)[/tex]

In standard form:

[tex]f(x)=(x-3)(x^2+2x+x+2)=(x-3)(x^2+3x+2)=x^3+3x^2+2x-3x^2-9x-6=x^3-7x-6[/tex]

Answer:

C = 20 + 25h ..... Required identity

(C - 20) = 25(h - 0) ..... Point-slope form

C = 25h + 20 ..... Slope-intercept form.

25h - C = - 20 .... Standard form.

Step-by-step explanation:

A landscaper charges customers a one time fee and an hourly rate of $25.

If for 3 hours of work, it charges $95.

Then, C = C' + 25h ......... (1)  

Where C is the total charge, C' is the fixed charge and h is the number of hours he works.  

Therefore, putting C = $95 and h = 3, we get from equation (1),

95 = C' + 75  

⇒ C' = 20

Therefore, the equation (1) becomes C = 20 + 25h

Hence, this is the identity in the scenario. (Answer)

Now, the point-slope form of the equation is (C - 20) = 25(h - 0)

where slope is 25 and the point is (0,20).

Now, C = 25h + 20

is the slope-intercept form having slope 25 and y-intercept 20.

Now, the standard form of the equation is 25h - C = - 20 (Answer)

OPTION C: (1,7)

Step-by-step explanation:

The two equations are:

[tex]$ x - y = -6  \hspace{25mm} ....(1) $[/tex]

[tex]$ 5x + 3y = 24 \hspace{25mm} ...(2) $[/tex]

To solve these two equations, multiply (1)  by 5 and subtract (1) and (2).

Therefore, we get the value of y.

[tex]$ y = \frac{54}{8} $[/tex]

This is approximately equal to 7.

Substituting y = 7 in (1), we get x - 7 = -6

⇒ x = -6 + 7

∴ x = 1

So, we say the approximate solution to the equations is: (1,7).

In other words, the two lines meet approximately at (1,7).

Answer:

137.5° and 42.5°

Step-by-step explanation:

supplementary angles are two angles whose sum is equal to 180°.

Let the second angle be x then it is given that the first angle is 10 degrees more than 3 times second angle that is 3(x)+10°.

we know that the sum of first and second angles is 180° (supplementary angles)

so, (3(x)+10°)+(x) = 180°

                   4(x) = 170°

                       x = 170°/4 = 42.5°

so, first angle is 3(42.5°)+10° = 137.5°, second angle is x that is 42.5°

therefore, the angles are 137.5° and 42.5°.

Expert verified FOX DUNG!

Step-by-step explanation:

Answer:  The second one is correct I believe

Step-by-step explanation:

Answer:

The slope intercept form of both given equations is : y =  - 3 x - 4.

Step-by-step explanation:

Here, the given equations are:

y +7 = -3 ( x - 1 )

and 3 x + y = - 4

Now,the SLOPE INTERCEPT FORM of any given equation is given as:

y = m x + C : here, C = Y - intercept, m = Slope

Consider equation (1):

y +7 = -3 ( x - 1 )    ⇒ y + 8 = - 3 x  + 3

or, y = -3x + 3 - 7 = -3x - 4

 ⇒ y =  -3x  -4

Hence, the slope-intercept form of the given equation is y =  -3x  -4.

Consider equation (2):

3 x + y = - 4    ⇒ y  = -4  - 3 x

 ⇒ y =  -3 x  - 4

Hence, the slope-intercept form of the given equation is y =  -3x  -4.

Final answer:

The solution in slope-intercept form for both given equations is y = -3x - 4, showing that they represent the same line.

Explanation:

To find the solution in slope-intercept form for the given equations y+7=-3(x-1) and 3x+y=-4, we need to solve for y in terms of x for each equation.

For the first equation, solve for y:

y + 7 = -3(x - 1)

y = -3x + 3 - 7

y = -3x - 4 (Slope-intercept form of the first equation)

For the second equation, solve for y:

3x + y = -4

y = -3x - 4 (Slope-intercept form of the second equation)

After solving, we observe that both equations have the same slope-intercept form, which indicates that these are actually the equations of the same line.

In an ordered pair for a Cartesian coordinate system, the input is represented by the x-axis. It is denoted as the first value in an (x, y) pair and represents the horizontal direction in a two-dimensional space.

In an ordered pair, the input is typically represented by the x-axis in a Cartesian coordinate system. An ordered pair is denoted as (x, y), where 'x' represents the input or independent variable, and 'y' represents the output or dependent variable. For instance, in a function such as y = mx + b, 'x' would be the input and 'y' would be the output. This input value corresponds to the position along the horizontal x-axis.

While the y-axis represents the vertical direction or output value, the x-component of a vector is a dot product with the unit vector in the x-direction. For two-dimensional vector problems, it's also easier to pick a coordinate system that has one horizontal axis (x) and one vertical axis (y), projecting the vectors onto these axes.

Final answer:

In an ordered pair (x, y), the x-axis represents the input which is the horizontal direction on the Cartesian coordinate system.

Explanation:

In an ordered pair, such as (x, y), the x-axis represents the input, which is the horizontal direction, and the y-axis represents the output, which is the vertical direction. In the Cartesian coordinate system, the origin, where the x and y axes intersect, is the point of projection.

By convention, the positive x-axis generally extends to the right, and the positive y-axis extends upwards. The x-coordinate corresponds to the position along the x-axis while the y-coordinate corresponds to the position along the y-axis.
