Area of a triangle = (bh)/2
a = bh/2
a * 2 = bh
(a * 2)/b = h
(27 * 2)/6 = h
54/6 = h
9 = h
We know that a = b and c = 30
Since b + 30 = 90, we know b = 60.
That means a = 60
a = 60
b = 60
c = 30
A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
Answer:
Option D. -0.901
Step-by-step explanation:
we know that
<u>The correlation coefficient</u> r measures the strength and direction of a linear relationship between two variables. The value of r is always between +1 and –1
Using a Excel tool (Correl function)
The value of coefficient r is -0.9006876
Round to three decimal places
r=-0.901
see the table attached
460= 40+ 12x
X equal the cost per month, which is what we're looking for.
460=40 +12x
-40 -40
420=12x
420/12= 35
So they would pay $35 per month with the $40 fee, as seen in the $460 fee.
