Haeden observed that 65% of her coworkers prefer the local talk news radio station. If 28 of her coworkers do not prefer talk ne
vekshin1

Part A


Let x represent the number of coworkers who prefer the talk news radio.


65% prefer the talk news radio,



100-65=35% will be the percentage that corresponds to coworkers who do not prefer the talk news radio.


Part B


We apply ratio to find x.




65:x



35:28


Hence number that corresponds to 65% will be greater than 28.


If more, less will divide.


This implies that,



x=\frac{65\times 28}{35}=52


Hence 52 of her coworkers prefer the local news talk station.

Lydia graphed ADEF at the coordinates D (-2,-1), E (-2, 2), and F (0,0). She thinks ADEF is a right triangle. Is Lydia's asserti
Setler79 [48]

The true statement is (c) No; the slopes of segment EF and segment DF are not opposite reciprocals.

<h3>Right triangles </h3>

Right triangles have a pair of perpendicular lines

Coordinates

The coordinates are given as:

  • D = (-2,-1)
  • E = (-2,2)
  • F = (0,0)

<h3>Slopes</h3>

Start by calculating the slopes of lines DF and EF using:

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m_{DF} = \frac{0 + 1}{0 +2}

m_{DF} = \frac{1}{2}

Also, we have:

m_{EF} = \frac{0 -2 }{0+2}

m_{EF} = \frac{-2 }{2}

m_{EF} = -1

For the triangle to be a right triangle, then the calculated slopes must be opposite reciprocals.

i.e.

m_1 = -\frac{1}{m_2}

By comparison, the slopes of both lines are not opposite reciprocals.

Hence, the true statement is (c)

Solve 3x^2 = −12x − 15.
vitfil [10]
3x^2+12x+15=0


Then divide by 3 to get the x by itself. 
x^2+4x+5=0


Factor to (x+5) (x-1) and solve for the two values of x.

What is the value of b?<br> 75<br> 100<br> 90<br> 80
Vladimir [108]

Hello from MrBillDoesMath!

Answer:

80


Discussion:

Per the attachment,  arc AB spans 110 degrees and arc BC spans 90 degrees (as that is the measure of the central angle subtending it). Hence arc ABC spans 110 + 90 = 200 degrees. As a circle has 360 degrees the smaller arc CA spans  360 - 200  = 160 degrees.  But angle"b" is a tangent chord angle so its measure equals 1/2 the arc spanned, that is 1/2 ( 160 ) = 80 degrees


Thank you,

MrB
