P+(2p-250)=2858 where p equals East High School's population
simplify (combine like terms)
3p-250=2858
add 250 to each side of the equation
3p=3108
divide each side by 3
p=1036
1036 students attend East High School.

Answer:

R = 3.057% per year

Step-by-step explanation:

This is a compound interest question

From the question, we have the following information

P = Principal = $1,725.95.

A = Amount after 25 years = $3,703.05

T = Time = 25 years

n = Compounding frequency = compounded monthly = 12

r = interest rate = ???

The formula to calculate the interest rate in a compound interest question =

r = n[(A/P)^1/nt - 1]

r = 12[($3,703.05/$1,725.95)^1/12× 25 - 1]

r = 3.057%

Therefore, the interest rate on the account is 3.057%

Answer:

(a)x=128 degrees

(b) $\angle APD\neq 116^\circ$

Step-by-step explanation:

$\angle ABD+\angle CBD =180^\circ$ (Linear Postulate)\\\angle ABD+116^\circ =180^\circ\\\angle ABD=180^\circ-116^\circ\\\angle ABD=64^\circ$

(a) Now:

$\angle AOD=2 \times \angle ABD$ (Angle at the centre is twice the angle at the circumference)\\x=2 \times 64^\circ\\x=128^\circ$

(b)

$\angle APD=2 \times \angle ABD$ (Inscribed Angle Theorem)\\\angle APD=2 \times 64^\circ\\ \angle APD=128^\circ$

$\angle APD\neq 116^\circ$
