20% of the seventh-grade students have math class in the morning. 16 2/3 % of those students also have science class in the morn
Lena [83]
Let x be the number of seventh grade students.

The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.

The 16 2/23% of those students also have science class in the morning means:

16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning

30 students have math in the morning but not science in the morning

83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180

There are 180 seventh graders.

What is the slope of the line that contains the points (–5, 6) and (14, –7)?
Morgarella [4.7K]

%  (a,b)
&&(~ -5 &,& 6~) 
%  (c,d)

\end{array}
\\\\\\
% slope  = m
slope =  m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-7-6}{14-(-5)}\implies \cfrac{-7-6}{14+5}\implies \cfrac{-13}{19}

In the diagram below, the angle of depression from the top of the lighthouse to a speed boat is 27 degrees.  The base of the lig
elixir [45]

Answer:

=

412

feet

Step-by-step explanation:

The angle of depression is always measured from the horizontal.

A triangle is formed by the lighthouse, the ground and the boat. The angle of depression is not in the triangle, but it is equal to the angle of elevation at the boat. (Alternate angles on parallel lines)

The angle at the top of the lighthouse, inside the triangle is:

90°−27°

=63°

The distance to the boat is the side opposite the angle of

63°

while the height of the lighthouse is the adjacent side.

opposite

adjacent

=tan 63°

distance

210=tan 63°

distance=210×tan 63°=412 feet

PLZ HELP!!! CORRECT ANSWER ONLY PLEASE<br><br> What is the value of x?
irina1246 [14]

Answer:

  x = 98 mm

Step-by-step explanation:

The angle bisector YT divides the triangle into proportional segments:

  VY/VT = KY/KT

Filling in the numbers and multiplying by VT, we have ...

  VY/57 = 68/129.2

  VY = 57·68/129.2 = 30

Then we can find x from ...

  x = VY + YK = 30 +68 = 98 . . . mm

The value of x is 98 mm.
