Answer:
-1/4
Step-by-step explanation:
The slope-intercept form is y
=
m
x+b
,
where m is the slope and b is the y-intercept.
y
=
m
x
+
b
Using the slope-intercept form, the slope is 4.
4 m
=
4
The equation of a perpendicular line to
y
=
4
x

The answer you are looking for is 45
We have to set up 2 equations:
A) x + y = 10 liters
B) .05x + .25y = 10 * .10
Multiply equation B) by -4
B) -.2x - y = -4 then add to equation A)
A) x + y = 10 liters
.8x = 6 liters
x = 7.5 liters of 5%
y = 2.5 liters of 25%
Answer:
64
mm² or approximately 201.06 mm²
Step-by-step explanation:
If the diameter is 16 mm, the radius will be 8 mm.
Use the circle area formula, A = r², where r is the radius. Plug in 8 as r:
A = r²
A = (8²)
A = 64
So, the area of the circle is 64 mm² or approximately 201.06 mm²
