Answer:
KL = 3
Step-by-step explanation:
It appears we are to assume that K lies between J and L, so we have ...
JK +KL = JL
(2x+3) +(x) = (4x)
3x +3 = 4x
3 = x . . . . . . . subtract 3x
KL = 3
Answer:
Option D. 
Step-by-step explanation:
tan ( 90-A ) = 
since sin (90-A) = cos A
and cos (90-A) = sin A
So 
Option D. is the correct answer.
Answer:
surface are: 300 cm2
volume: 450cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Surface area of a box = 2wl + 2hw + 2 lh
Where w is the width of the box, l is the length of the box, and h is the height of the box.
The top sides and bottom have only length and width, since there is no top side, the surface area is equal to the outer 5 surfaces.
S = wl + 2hw + 2 lh
Replacing with the values given:
S = (15x10)+ 2(3x10)+ 2(15x3)
S = 150+60+90=300 cm2
For the volume we simply apply:
Volume of a rectangular prism: length x width x height
V = 15x10x3 = 450cm3
Feel free to ask for more if needed or if you did not understand something.
Answer:
$80
Step-by-step explanation:
100%-30%=70%(nightstand after discount)
70%=$56
1%=56÷70=0.80
100%=0.8x100=80
Hope this helps! Thanks.
