£600 is invested into a savings account paying 5% compound interest per year. How much is in
the account after three years

£694.575

Step-by-step explanation:

Using the formula for calculating the compound interest expressed as;

A = P(1+r)^t

P is the principal = £600

r is the rate = 5% = 0.05

t is the time = 3 years

Substitute into the formula;

A = 600(1+0.05)^3

A = 600(1.05)^3

A = 600(1.157625)

A = 694.575

hence the amount in the account after 3 years is £694.575

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
