Answer:
The answer is B(65)
Step-by-step explanation:
you just do 180 - JCB = 65
so you do 180-65=115
hope this helps
Answer:
w= -3.75
Step-by-step explanation:
-5(4w+12) =15
-20w -60=15
-20w=75
w=-3.75
the coordinates of the points of intersection of the graph of y=13−x with the axes
Given equation is y=13-x
x axis is x=0
y axis is y=0
Plug in the value of x =0 and find out y
y = 13 - x
y = 13 - 0 = 13
Plug in the value of y=0 and find out x
0 = 13 - x
x= 13
So coordinate axis
x= (13,0)
y= (0,13)
Base of the triangle is x=13
Height of the triangle is y= 13
Area of the triangle = 
=
= 84.5
Area of the triangle = 84.5
We have that
the first balance indicates--------> 10 g
the second balance indicates--------> 0 g
the third balance indicates--------> 7.5 g
therefore
the <span>mass of the chick is (10+0+7.5)----> 17.5 g
the answer is
17.5 g</span>
