Answer:

B

Step-by-step explanation:

Given the 2 equations

a - b + c = 3 → (1)

a + b + c = 7 → (2)

Subtract (1) from (2) term by term to eliminate a and c

a - a + b - (- b) + c - c = 7 - 3 , that is

0 + b + b + 0 = 4

2b = 4 ( divide both sides by 2 )

b = 2 → B

jenyasd209 [6]

Answer:

11 years.

Step-by-step explanation:

Given that Carter invested $ 16,000 in an account paying an interest rate of 5.6% compounded monthly, to determine, assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $ 29,600, the following calculation must be performed:

16,000 x (1 + 0.056 / 12) ^ Yx12 = 29,600

Y = 11

16,000 x 1.4666 ^ 132 = X

29,581.70 = X

Thus, rounded to the nearest year, it would take 11 years for the account to reach $ 29,600.

The area (A) of a circle with a radius of r is given by the formula and its diameter (d) is given by . Arrange the equations in
ella [17]

Answer:

see explanation

Step-by-step explanation:

A = πr² ← r is the radius and r = \frac{1}{2} d ← d is the diameter

Hence

π (\frac{1}{2} d)² = A, that is

\frac{d^2\pi }{4} = A ( multiply both sides by 4 )

d²π = 4A ( divide both sides by π )

d² = \frac{4A}{\pi } ( take the square root of both sides )

d = \sqrt{\frac{4A}{\pi } }
