Airplanes use radar (radio waves) to measure distances.

The plane is at a height of 5200 m. The airport is 10.2 km away.

How far does the plane need to travel before it lands?


a) 11.4 km

b) 10.4 km

c) 5200 km

d) 10.2 km

Answers

Answer 1

Answer:

10.2 km

Step-by-step explanation:

I thought we have to add 5200 m + 10,2 km, but for this result there is no an alternative. So the correct answer must be 10,2 km, if the plane is right above the airport.

Answer 2
D is the answer, hope it helped

Solve:
14x+y=7
Write your answer in the following format:
with no spaces.

Answers

Answer:

x = 7/10; y = 21/5

Step-by-step explanation:

y = 6x

4x + y = 7

Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.

4x + y = 7

4x + 6x = 7

10x = 7

x = 7/10

Now we use the first equation and substitute 7/10 for x and solve for y.

y = 6x

y = 6 * 7/10

y = 42/10

y = 21/5

Answer: x = 7/10; y = 21/5

Given A(5, –2), what are the coordinates of (T⟨−3, 4⟩∘ Rx-axis)(A)?

Answers

Answer:

not sure

Step-by-step explanation:

Following are the calculation to the given coordinates:

[tex]\to T (-2, 5)[/tex]

The y-axis reflection:Modify its abscissa's sign, i.e., the x-coordinate.Keep this ordinate, which would be the y-coordinate.

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

Also, as a result, the coordinates of point T' after the Ry-axis are as follows: (2, 5).

Whenever a point is reflected throughout the x-axis, the x-coordinate is unchanged, but the "y-coordinate" is assumed to be the additional inversion.

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

As a result, the coordinates of point T' after the Rx-axis are just as follows: (-2, -5)

how many factors of 10 are in 10 of the third power?

Answers

Answer:2 times 5 equals 10

Step-by-step explanation:

"The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10." From ww.infoplease.com great resource

The required factor of 10 in 10 of the third power is 3.

What are the factors?

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

10 of the third power = 10³
10³ = 10×10×10
The expression 10×10×10 has 3, 10's

Thus, the required factor of 10 in 10 of the third power is 3.

To find:

The slope of the line that described by the data in the table.

Solution:

Consider any two points from the given table.

Let the two points are (0,8) and (4,13). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{13-8}{4-0}[/tex]

[tex]m=\dfrac{5}{4}[/tex]

A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle.

True or false??

Answers

Given:

The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."

To find:

Whether the given statement in true or false.

Solution:

Area of circle is

[tex]A=\pi r^2[/tex]

Where, r is the radius of the circle.

Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is

[tex]A_1=\pi (r_1)^2[/tex]

The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:

[tex]r_2=1.5r_1[/tex]

The area of the new circle is

[tex]A_2=\pi (r_2)^2[/tex]

[tex]A_2=\pi (1.5r_1)^2[/tex]

[tex]A_2=2.25\pi (r_1)^2[/tex]

[tex]A_2=2.25A_1[/tex]

The area of the new circle is 2.25 times the area of the original circle.

Therefore, the given statement is false.

Total budgeted amount = 78

The number of books, x that can be ordered can be represented by the inequality :
