Answer:
right answer is 8cm
Step-by-step explanation:
if QM=x
so. Om=32+x
ON=64+16=80
(32+x)/x=80/16
32+x=5x
4x=32
x=8
Answer:
$20-$12=
Step-by-step explanation:
20-12=8
Answer:
If the time passed is only 3 months, then it is $2040
Step-by-step explanation:
We can use the quarterly compounded interest equation for this problem: P(1 + r/n)^nt
Step 1: Find out how much 3 months is in a year
<em>In this case, 3/12 which is 1/4</em>
Step 2: Plug in known variables into equation
2000[1 + (0.08)/4)]^[(4)(1/4)]
Step 3: Solve/Plug in calc
You will get $2040
If the time passed in the problem is 1 year, then we can be able to solve how much money he earned per quarter. However, since only 3 months have elapsed, then he has only earned $2040.
I'm not sure if you meant the tax was on the original proce or not, so here's both answers:
Tax on original price: $3010
Tax after sale: $2968
To get the amount off from the sale
3500x.2=700
3500-700=2800
To get the tax
(Tax on original price) 3500x.06=210
(Tax after sale) 2800x.06=168
Add tax onto price
(Tax on original price) 2800+210=3010
(Tax after sale) 2800+168=2968
