Answer:
A: $958.50
Step-by-step explanation:
Since we are solving how much money in total he will receive in one year, we know that annually means once a year. Therefore to solve this, we need to divide 6.5 by 100 since the way to turn a decimal into a percent is to multiply by 100, and we are trying to make it a decimal.
6.5 ÷ 100 = 0.065.
Next, we need to multiply 0.065 by 900. This is because we originally need to divide the denominator (900) from the numerator (X).
0.065 x 900 = 58.5 = $58.50
Now that we know 6.5% is equivalent to $58.50, we just need to add $900 and $58.50.
$900 + $58.50 = $958.50
The solution to your math problem is A: $958.50. Lan will have $958.50 by the end of one year.
Answer:
There were 10 people in team one.
Step-by-step explanation:
Let x= team one.
Let y= team two
Because there four times less people in team one than in two we know that x=(1/4)y
After 6 people quit and 12 people transfer from team two, the two teams become equal. Therefore, x + 12 = y - 6 - 12.
You can then insert the initial equation for x into the second equation and know that there were 10 people in team one and 40 people in team two.
132.88/88=1.51
1.51*100=151
the normal price is £151
Answer:
Step-by-step explanation:
exponents raised to a - power is an inverse function probably not the right word
a^-b = 1/(a^b) example 4^-2 = 1/(4^2) = 1/16
so (7^-1)^-1 is a double inverse which is back to the original number 7
inverted 7 twice
(7^-1)^-1 = (1/7)^-1 = 1/(1/7) = 7 trust me or use your calculator
since the coeffients are the same just add the powers... some exponent rule
5^2 * 5^4 * 5^-3 = 5^(2+4-3) = 5³
here is it written out
5^2 * 5^4 * 5^-3 = 5² × 5^4 × 5^-3 = (5×5) × (5×5×5×5) × (1/5×1/5×1/5)
5×5 × 5× (5×5×5 × 1/5×1/5×1/5) (5×5×5 × 1/5×1/5×1/5) = 1
5×5×5 = 5³
so
