Work out the balance for £1500 invested for 2 years at 3.7% per annum

Mathematics
1 answer:
pogonyaev3 years ago
4 0
Given:
Principal = 1,500
term = 2 years
interest rate = 3.7% per annum

Simple Interest = Principal * interest rate * term
S.I = 1,500 * 0.037 * 2
S.I = 111

Total value = 1,500 + 111 = 1,611

Compound interest
A = P (1+r/n)^nt
where n is the number of times interest is compounded. Assuming interest is only compounded once.

A = 1,500(1+0.037/1)^1*2
A = 1,500(1.037)²
A = 1,500(1.075369)
A = 1,613.0535

What's the solution set of –5 < 2x – 1 < 3?
Dmitry [639]

Answer:

The answer is - 2 < x < 2

Step-by-step explanation:

–5 < 2x – 1 < 3

Add 1 to both sides to eliminate - 1

That's

- 5 + 1 < 2x - 1 + 1 < 3+ 1

- 4 < 2x < 4

Divide both sides by 2

That's

- 4/2 < 2x/2 < 4/2

The final answer is

<h3 /><h3>- 2 < x < 2</h3>

in 15 years Pam hope to have $30,000to make a down payment on a house. how much would she need to invest right now in a mutual f
Goryan [66]

Answer:

She needs to invest $13,636.36 right now

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

In this question:

In 15 years, so t = 15

She wants to have $30,000, so T = 30000

8% interest, so I = 0.08

We have to find P.

T = E + P

30000 = E + P

E = 30000 - P

Replacing:

E = P*I*t

30000 - P = P*0.08*15

30000 - P = 1.2P

2.2P = 30000

P = \frac{30000}{2.2}

P = 13636.36

She needs to invest $13,636.36 right now

Find a counterexample: Two sides of a
Shkiper50 [21]

Answer: Any isosceles triangle is a counter example. More specifically, a triangle with sides 7, 7 and 3

When forming your triangle, make sure you apply the triangle inequality theorem. This is the idea where adding any two sides leads to a result larger than the third side. So we have

7+7 = 14 which is larger than 3

7+3 = 10 which is larger than 7

By definition, an isosceles triangle has two congruent sides. Some books say "at least 2 congruent sides", but I'll go with the first definition. If you want all three sides to be congruent, then you'd go for the term "equilateral".
