Let's say the tv was 100$ . Reduced by 20% means the tv is now 100 - 20 = 80% of the original price.
0.8(100) = 80$
Reduced again; by 10% means that it is now 100-10 = 90% of the 80$
0.9(80) = 72$
sale price ÷ original price
72$ / 100$ = 0.72 which is 72% of the original price. Which is a mark down of:
100 - 72 = 28%
The new price is 28% lower than the original price.
Answer: 42 units squared
Step-by-step explanation:
3x7=21
3x7=21 divided by 2 = 10.5 + 10.5 = 21 so,
21+21=42
Hope it helps
If 3% out of 100% are defective it would be 3 out of every 100, and 3 multiplied by 5 is 15. Then you multiply 100 by 5 and its 500 so out of 500 parts 15 would be defective
Answer:
y=-x
Step-by-step explanation:
The y-intercept is 0 and the slope is -1 so -x.
Answer:
y = -x+6
Step-by-step explanation:
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -1x+b
Substitute the point into the equation
-8 = -1*2 +b
-8 = -2+b
-8+2 = -2+b+2
-6 =b
y = -x+6
