Answer:
The forth one:No,the addition symbol was dropped in the second expression
Step-by-step explanation:
I took the quiz and got it right
0.1 < 0.2 < 0.3
Since 1/5 = 0.2 and 30% = 30/100 wich is 0.3
Answer:
Step-by-step explanation:
- Principal P = $2250
- Interest rate r = 2.4% = 0.024 PA compounded
- Compound number n = 1 (once per year)
- Time t = 6 years
<u>Future amount formula:</u>
<u>Substitute given values:</u>
- F = 2250(1 + 0.024)^6 = 2594.07
It is given that
a+b=20 -------------------- (1)
b+c=30 -----------------------(2)
We have to calculate
3 a + 4 b +7 c
Now multiplying equation(1 )by 3,we get
3 a+ 3 b=60 ----------------------------------(3)
and Multiplying equation( 2) by 4,we get
4 b + 4 c=120 -----------------------------------(4)
Adding expression (3) and (4),we get i.e left hand side of 3 to left hand side of 4 and right hand side of 3 to right hand side of 4.
3 a+ 3 b+ 4 b+ 4 c=60+120
Adding like terms, we get
3 a+ 7 b+ 4 c =180, Which is the required solution.
Answer:
$3450
Step-by-step explanation:
The cost of one computer is the sum of the cost of the parts:
$120 +100 +45 +30 +50 = $345
Then the cost of 10 of them is ...
10 × $345 = $3450 . . . . cost for 10 computers
