You are given the
length of the chain equal to 28.9cm. For each link, the length is 1.7cm long. You
are required to find how many links are there in the chain. You just divide
28.9 cm by 1.7 cm to get the answer. The solution is,
<span>
Number of links =
chain length/link length</span>
Number of links = (28.9cm)/(1.7cm)
<span>Number of links =
chain length/link length</span>
Number of links = 17
<span><u><span>There are 17
links in a 28.9cm chain length.</span></u><u /></span>
First of all, for median, <em>list the numbers in order.</em>
60, 60, 66, 70
If there are an odd number of numbers, the median is the number in the middle.
If there are an even number of numbers, the median is the average(mean) of the two numbers closest to the middle.
Average of 60 and 66:
60+66 = 126
126/2 = 63
Median: 63
Answer:
x=12
Step-by-step explanation:
the difference is multiply by 3
4*3=12
Answer: in the 1% account we have $2600 and in the 6% account we have $2400.
Step-by-step explanation:
We have two amounts A and B such that:
Where A is the amount invested in the 1% earning interest account and B is the amount invested in the 6% earning interest account.
A + B = $5000,
If the interest is yearly, then we have that, after one year, the interest is:
A*(1%/100%) + B*(6%/100%) = $170
A*0.01 + B*0.06 = $170
So we have two equations:
A + B = $5000
A*0.01 + B*0.06 = $170
In the first equation we can isolate A and get:
A = $5000 - B
and replace it in the other equation:
($5000 - B)*0.01 + B*0.06 = $170
$50 + B*0.05 = $170
B*0.05 = $120
B = $120/0.05 = $2400
Then A = $5000 - $2400 = $2600.
