Answer:
a=-0.01
Step-by-step explanation:
Divide by -20 on both sides:
0.2/-20=-20a/-20
which will be:
-0.01=a
440*6=2640
So the answer to A. is $2640
2640-2445=195
Which means the fee is $195
Umm... I really dont get maths in my brain. Dont mind me though :P .
but i can sure tell u a little i know .
4x-1+2x-5+30=180 (sum of interior angles of triangle)
or, 6x+24=180
or, 6x=156
therefore, X=26 degrees
thankyou :D
Answer:
perimeter: 22ft
area:
be warned, i dont know if the are is correct but that is what I calculated.
Step-by-step explanation:
The area is measurement of the surface of a shape. To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.
Answer:
100 cm
since B,C are the two midpoints of ZY,XZ then BC is parallel to side XY and equal half of its length then XY equal 30 cm and simce A,B are the midpoints of XY,YZ then AB equal half XZ then XZ equal 36 cm then the perimeter of XYZ equals 36+30+34 equals 100 cm
