The formula we'll use for this is the simple interest formula, or:
Where:
<span><span>P is the principal amount, $4000.00.
</span><span>r is the interest rate, 12% per year, or in decimal form, 12/100=0.12.
</span><span>t is the time involved, 3....year(s) time periods.
</span><span>So, t is 3....year time periods.
</span></span>
To find the simple interest, we multiply 4000 × 0.12 × 3 to get that:
<span>
The interest is: $1440.00</span>
Step-by-step explanation:
make another column with the heading difference. now, the difference between the children's ages will always be the same. so now you have to make the ratio the same.
NOW:
Child A:Child B:difference
3: 2 : 1(3units-2 units)
10 years later
Child A:Child B:difference
7: 6. : 1(7 units-6 units)
since the difference us the same for both ratios, now we can compare between both sets of ratios.
take for example child A:
the number of units increased in 10 years is 7 units-3 units=4 units
4 units is 10 years
1 unit is
and therefore one child is 5 years old and the other is 7 and a half.
NOTE: IT IS THE SAME IF YOU USED CHILD B.
take for example child B:
the number of units increased in 10 years is 6 units-2 units=4 units
and if you continue to solve, you will find that you arrive at the same answers.
hope this helps!!!!
Answer:
C) (-2, -1)
Explanation:
The graphs meet at the point (-2, -1), therefore C is the solution.
Answer:
Step-by-step explanation:
rewrite you problem with the number as x
22(11) + 10 numbers next to eachother mean to multiply
242 + 10
252
