Answer: total is 200
Step-by-step explanation:
30% = 60
10% = 60/3 = 20
100% = 200
Answer:
y = -2/5x -6
slope is -2/5
y intercept -6
Step-by-step explanation:
8x+20y=-120
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 8x from each side
8x -8x+20y= -8x-120
20y = -8x - 120
Divide by 20
20y/20 = -8x/20 -120/20
y = -2/5x -6
Answer:
Set up an equation
-4+x=4 Add 4 to each side
x=8
So
-4 plus eight is 4
Given:
AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.
To find:
The
and
.
Solution:
AD is diameter of the circle. So, the measure of arc AD is 180 degrees.




The measure inscribed angle is half of the corresponding subtended arc.



AB is the tangent. So,
because radius is perpendicular on the tangent and the point of tangency.




Therefore,
and
.
Answer:
11.11%
Step-by-step explanation:
The selling price is 250
The cost price is 250-25
= 225
Therefore the gain can be calculated as follows
=250-225x/225x×100
1/9 ×100
= 0.1111×100
= 11.11%
Hence the gain is 11.11%
