Answer 1

Answer:

  CD = 3 -√3

Step-by-step explanation:

The ratio of leg lengths in a 30°-60°-90° triangle is ...

  1 : √3 : 2

The longest leg of ΔABD is 2√3, so we must multiply all of these ratio values by √3 to see the actual lengths of the triangle sides.

  AB : BD : AD = 1 : √3 : 2 = √3 : 3 : 2√3

That is ...

  AB = √3

  BD = 3

__

The lengths of the legs in isosceles right triangle ABC are the same, so ...

  BC = AB = √3

Then the length of interest is ...

  CD = BD -BC

  CD = 3 -√3 . . . . . . . a=3, b=-1

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

Solve by substitution (show work pls)
y= 2x-2
-3x+4y=-23

Answers

Answer:

x = -3 y = -8 (-3,-8)

Step-by-step explanation:

first you would subsitute the y with (2x-2) in -3x+4y=-23 as y=2x-2

giving you-3x+4(2x-2)=-23

next you distribute the 4 to (2x-2) leaving you with -3x+8x-8=-23

then add -3x+8x to get 5x, having 5x-8=-23

add 8 to both sides canceling out 8 on one side and adding 8 to the other leaving you with 5x=-15 then you divide 5 from 5x to both sides leaving you with x = -3

next is y since you have x you would substitute the x in y=2x-2 with -3 getting y=2(-3)-2 then you multiply the 2 and -3 so you have y=-6-2 then you subtract those getting y = -8

The graph shown models the speed of a racecar during part of a lap.

Take on the role of a racing announcer and create a story to describe what the graph reveals about the race. Include the following information in your story:

What do the line segments R, S, T, U, and V reveal about the speed of the car?
Include information about the speeds and times when writing your story.

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).

Hope it helped.

Hey, I’m not that sure but here it is:

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

Step-by-step explanation:

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