Robert gets a loan from his bank.
masya89 [10]

Answer:

£10200

Step-by-step explanation:

Amount borrowed (P) = £6000

Rate of interest (R) = 7%

Time (T) = 10 years

First, let us calculate the simple interest (SI) for 10 years.

Formula for simple interest is given as:

S.I.=\frac{PRT}{100}

Plugging the values of P, R and T in the above formula, we find:

S.I.=\frac{6000(7)(10)}{100}

S.I.= £4200

Total money paid back at the end of the 10 years

= £6000 + £4200

= £10200

What is the length of ST? Please explain your answer
Aliun [14]
We know that

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment. (Intersecting Secant-Tangent Theorem)

so

ST²=RT*QT

RT=7 in

QT=23+7-----> 30 in

ST²=7*30-----> 210

ST=√210-----> 14.49 in


the answer is

RT=14.49 in
