Answer:
10
Step-by-step explanation:
10+3 = 13
13 x 7 = 91
She has distributed the bracket incorrectly
(64 + 5) - 0.2(- 20 + 10)
=
(69) - 0.2 (- 10)
=34.5 + 2
= 36.5
66.6667
20=x/100•30
Solve this equation and you will get your answer (66.6667)
Answer:
5.46π cm³
Step-by-step explanation:
Volume of sphere= 4/3πr³
= 4/3×π×(1.6)³ cm³
=5.46π cm³

Answer:
d
Step-by-step explanation:
598.60
You are given the equation
A(t) = P*e^(rt)
Where P = Principal
r = interest rate
t = time
e is a mathematical constant equivalent to approx 2.71828
You're told the initial Principal is $500, the interest rate is 3%, over 6 years. So you have everything that you need to solve the problem, just plug in the values and solve for A(6)
A(t) = P*e^(rt)
A(6) = 500 * e^(0.03 * 6)
A(6) = 500 * e^(0.18)
A(6) = 500 * 2.71828^(0.18)
A(6) = 500 * 1.19721
A(6) = 598.60861
So $500 invested 6 years ago at 3% would be worth $598.61 today.
