Answer 1

Answer:

x=30

Step-by-step explanation:

i actually dont know but thnks for the points BTW

Answer 2

Answer:

  x = 4

Step-by-step explanation:

In this geometry, all of the right triangles are similar. That means the ratio of short side to long side is the same for all of the right triangles:

  x/10 = 10/25

  x = 100/25 = 4 . . . . . multiply by 10

_____

Additional comment

You may notice that the two segments of the hypotenuse, x and 25, have a product that is the square of the altitude. Another way to say this is that the altitude is the geometric mean of the segments x and 25.

There are two other geometric mean relations in this geometry:

  the short side at the right is the geometric mean of x and (x+25).

  the long side at the bottom is the geometric mean of 25 and (25+x).

That is, the segments that intersect the hypotenuse are the geometric mean of the two segments of the hypotenuse that they meet.

  geometric mean of A and B is √(AB)

HELP NEEDED!! 30 POINTS! BRAINLY TO BEST

Answers

Answer:

18

Step-by-step explanation:

By similar triangles law:-

[tex]\frac{24}{2x} =\frac{30}{x+6}[/tex]

[tex]24(x+6)=30(2x)[/tex]

[tex]24x+24(6)=60x[/tex]

[tex]24x+144=60x[/tex]

[tex]\frac{36x}{36x} =\frac{144}{36}[/tex]

[tex]x=4[/tex]

Since AB=x+6+2x

[tex]AB=3x+6[/tex]

Substitute value of x

[tex]AB=3(4)+6[/tex]

[tex]AB=12+6[/tex]

[tex]AB=18[/tex]

Therefore, the third side of ΔABC is 18.

How do you multiply two scientific notation values? Explain the steps you would take to find the product of 6. 7 × 106 and 3. 2 × 105 written in scientific notation.

Answers

The product of 6.7 × 10⁶ and 3.2 × 10⁵ can be written in scientific notation is 2.144  × 10¹².

What is multiplication?

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The two numbers are [tex]\rm 6.7*10^6 \ and \ 3.2 * 10^5[/tex]

Then find the product of these two numbers.

To multiply these terms is very simple.

First, multiple 6.7 and 3.2 simply. And the power of 10 gets added. That is

[tex](6.7*10^6) * (3.2 * 10^5) = 6.7 * 3.2 * 10^6 *10^5\\\\(6.7*10^6) * (3.2 * 10^5) = 21.44* 10^{6+5}\\\\(6.7*10^6) * (3.2 * 10^5) = 21.44 *10^{11}\\\\(6.7*10^6) * (3.2 * 10^5) = 2.144* 10^{12}[/tex]

The product of 6.7 × 10⁶ and 3.2 × 10⁵ can be written in scientific notation is 2.144  × 10¹².

Suppose that a rectangular piece of glass has a perimeter of 20 meters. If we multiply both its length and its width by 4, what will be the perimeter
of the new rectangular piece of glass?
A) 65 m
B) 80 m
C) 34 m
D) 45 m

Answers

Answer:

B) 80 m

Step-by-step explanation:

Let W = width

Let L = length

perimeter of a rectangle = 2 x width + 2 x length = 2(W + L)

If the perimeter of a rectangle = 20 m

⇒ 2(W + L) = 20

If we multiply both its length and width by 4:

Width = 4W

Length = 4L

⇒ perimeter = 2(4W + 4L) = 8(W + L)

As 2(W + L) = 20

Then 8(W + L) = 4 x 2(W + L) = 4 x 20 = 80 m

What do the line segments R, S, T, U, and V reveal about the speed of the car?

Answers

Answer:

A racer has just completed his first lap at a speed of 198m/s. Now his speed decrease or he decelerateted at 195m/s after 2s of his completion of first lap, as soon as he saw a curve path(line segment R). He then moved at a constant speed of 195m/s for the next 2s(line segment s). Then the race track after 4s of the completion of first lap was straight, so the racer accelerated to 200m/s within 2s( line segment T) and traveled at a constant speed for the next 6s( line segment U). After 12s from the first lap completion, he immediately saw a curve track, so he decelerateted to the speed of 194m/s within 3s( line segment V).

To find the percentage of people that play the violin, you first need to find the tots number of students. To do this add up all the students that play the different instruments. 14+12+10+4=40

Now divide the number of violin players by the total number of people in the orchestra. 14/40=0.35

Now multiply 0.35 by 100 to make it an actual percentage. 0.35*100=35

So 35% of the orchestra plays the violin
