Hello,
if we use Heron's formula:
p=(7.2+5.9+11.2)/2=12.15
Area=√(p*(p-a)(p-b)(p-c))
=√(12.15*(12.15-7.2)(12.15-5.9)(12.15-11.2))
=√357,09609375
=18,896986366878714557972599553433≈18.90
So i suppose Answer=D (with an error of 0.01)
Answer:
The answer for this is 5!
Step-by-step explanation:
<em>First, the two bottom angles are similar so add 52 and 52. After that subtract what you found from 180. A triangle has a total of 180 degrees in all three of their angles. </em>
<em>You will get 76. Then subtract 6 from that and divide by 14. There is your answer :)</em>
A:
Coefficient is a number multiplied by an unknown variable. Both 10.50 and 15 are coefficients
B:
You plug in the given values into the provided formula.
10.50(37) + 15(12) + 50
388.50 + 180 + 50 = 618.50
C:
Only the coefficient 10.50 would change to 11.25, because this is a representation of the dollar amount per hour that she works.

Answer:
y = x + 30
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 30) and (x₂, y₂ ) = (70, 40) ← 2 points on the line
m = = =
The line crosses the y- axis at (0, 30) ⇒ c = 30
y = x + 30 ← equation of line
