Answer:
-0.394875
Step-by-step explanation:
(9/16)*(-3/4)
9/16=.5265
-3/4=-.75
.5265*(-.75)=-0.394875
Linear pair angles have too add to 180, so
5x+9+3x+11=180
8x+20=180
8x=160
x=20
so angle S is 5*20+9 = 109
angle T is 3*20+11 = 71
Answer:
X = 1 - (1/4) - 2 * (1/4)
Step-by-step explanation:
The equation to be raised must take into account what is painted on Monday and Tuesday. First consider the wall as a unit, that is to say painting the entire wall (100%) is equivalent to 1. Therefore the equation would be the following:
Let X be the unpainted part:
<em>X = 1 - (1/4) - 2 * (1/4)
</em>
X = 1 - (1/4) - (1/2)
Now, if we solve this, we have that 0.25, therefore 25% or 1/4 is left to be painted on the wall.
Answer:
BC = 
= 49 unit
Step-by-step explanation:
The given as AC is a line with B as its mid point
AND ,
AC = 8x + 15
AB = 3x + 4
BC = 4x - 1
∵ AC = AB + BC
Or, 8x + 15 = ( 3x + 4 ) + ( 4x - 1)
Or, 8x + 15 = 7x + 3
Or, 8x - 7x = 3 - 15
∴ x = - 12
SO, AC = 8x + 15 = 8 × ( - 12) + 15 = - 81
Or, AC = 
= 81 unit
And ,AB = 3x + 4 = 3 × ( - 12) + 4 = - 32
Or ,AB = 
= 32 unit
Similarly BC = 4x - 1 = 4 × ( - 12) - 1 = - 49
Or, BC = = 49 unit Answer
