Answer:

length: 12 ft

area: 72 square feet

Step-by-step explanation:

Let L represent the length of the mat in feet. Then L/2 is the width and the perimeter is ...

P = 36 = 2(L +L/2) = 3L . . . . . substitute the given information and simplify

12 = L . . . . . . divide by 3

The length of the mat is 12 ft.

The width of the mat is L/2 = 6 ft, and the area is the product of length and width.

Area = (12 ft)(6 ft) = 72 ft^2

The area of the mat is 72 square feet.

A line has a slope of -6 over 7. What is the slope of the line parallel to it? And what is the slope of the line perpendicular t

olga_2 [115]

The slope of the parallel line is -6/7
the slope of the perpendicular line is 7/6
the slope of the line = -6/7
the gradient of two parallel lines are equal
the product of the gradient of two perpendicular lines is -1
: the gradient m1*m2 = -1
m2= -1(-6/7)
m2= 7/6

If a student didn’t understand proportional relationships, how would you explain it to them?

kirill [66]

Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent.

Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

I really recommend watching Khan Academy's video over proportional relationships, the speaker explains it very well!!

Which one is it A. B. C. or D.

nadya68 [22]

7x + 2y = 2
2x - y = 10

2y = - 7x + 2
- y = - 2x + 10

2y = -7x + 2
y = 2x - 10

$y=\frac{-7x+2}{2}$
y= 2x - 10

y = -3.5x + 1
y = 2x - 10

Now, let's find "x" first by doing a substituion !

2x - 10 = - 3.5x + 1
y = 2x - 10

2x + 3.5x = 1 + 10
y = 2x - 10

5.5x = 11
y= 2x - 10

$x = \frac{11}{5.5}=2$
y= 2*2 - 10 = 4 - 10 = -6

In short, the answer would be : y = -6 (Option B).

Hope this helps !
