Answer:
Step-by-step explanation:
Rectangle piece of fabric has an area of (L*W =A) 18 * 14 = 252 sq cm. Each triangle being 64 sq cm, so total area of fabric divided by area of square 252/64 = 4 triangle for one square of 18x14 piece of fabric.
If you have 35 Squares, each can make 4 triangle. 35*4= 140
Answer:
Perpendicular
Step-by-step explanation:
Linear equations will describe parallel lines when the lines have the same slope. These equations are written in slope-intercept form, so we can easily determine that the slopes are ...
f(x): slope is 5/6
g(x): slope is -6/5
These are not the same, so the lines are not parallel.
__
The lines will be perpendicular when the product of their slopes is -1. Here, that product is ...
(5/6)(-6/5) = -30/30 = -1
These equations describe lines that are perpendicular.
Answer:

Step-by-step explanation:
(a)
x + y = 15 → (1)
(b)
xy - yx = 27 ( take into account the place value of the digits )
10x + y - (10y + x) = 27
10x + y - 10y - x = 27
9x - 9y = 27 → (2)
(c)
Multiply (1) by 9
9x + 9y = 135 → (3)
Add (2) and (3) term by term to eliminate y
18x = 162 ( divide both sides by 18 )
x = 9
Substitute x = 9 into (1)
9 + y = 15 ( subtract 9 from both sides )
y = 6
Thus the original number = (9 × 10) + 6 = 90 + 6 = 96
Answer:
T=-13
Step-by-step explanation:
substitute T=3*5+4*(-7)
the product:T=15-28
the sum:T=-13
