The answer is y=3x.

y=21, x=7
y=mx (m is the variable for slope)
21=m(7)
m=21/7
m=3

Given ∆ABC≅∆PQR, mb=8v-9 , find m 31°<br> b.<br> 52°<br> c.<br> 49°<br> d.<br> 32°
Ipatiy [6.2K]
Here, 5v+6 = 8v-9
8v - 5v = 6 + 9
3v = 15
v = 15/3
v = 5

So, m<b = 5(5) + 6 = 25 + 6 = 31
As they are congruent, m<q would be same [ 31 degree ]

In short, Your Answer would be Option A

Hope this helps!

If the radius of a circle is 3 meters, how long is the arc subtended by an angle measuring 30°?
FromTheMoon [43]
Circumference of entire circle = 2 * PI * radius
2 * PI * 3 = <span> <span> <span> 18.8</span></span></span>5 meters
a 30 degree arc is (30/360) or 1/12 of a circle.
So the arc equals (18.85 meters / 12) or <span> <span> <span> 1.57</span></span></span> meters.

Help me find the surface area of the candle
ExtremeBDS [4]

Answer:

Easy!

Step-by-step explanation:

1) To find the surface area of a regular triangular pyramid, we use the formula SA = A + (3/2)bh, where A = the area of the pyramid's base, b = the base of one of the faces, and h = height of one of the faces.

or

2)Multiply the side length of the base by the slant height and divide by two. Then, multiply by 4. This will give you the lateral surface area of the pyramid. Add the base surface area and the lateral surface area.

For what values of the variable are the following expressions defined?
Rom4ik [11]

Answer:

  • The Expression will be defined if the denominator is not equal to 0 since any number divided by 0 is undefined.
  • Therfore our main priority here is to check the denominator only because it's the only part that can make the expression undefined
  • the expression will be defined for all real numbers (a) BUT 3+a must not equal to 0 therfore (a) can be all real numbers but must never be equal to -3

Step-by-step explanation:

  • a \: is \: an \: element \: of \: all \: real \: numbers \: but \: not \: not \: equal \: to \:  -3
  • HOPE THIS HELPS!
