1. An account is opened with a balance of $2800earning 4.25% simple interest. What will be thebalance in the account in 30 years
JulijaS [17]

Answer:

$6370

Explanation:

The simple interest formula gives us the final amount A given the principal amount P:

A=P(1+rt)

where r is the interest rate and t is the time interval.

Now in our case we have

P = 2800

r = 4.25/100

t = 30 years

therefore, the above formula gives

A=2800(1+\frac{4.25}{100}\cdot30)

which simplifies to give

\boxed{A=\$6370}

Hence, the account balance after 30 years will be $6370.

The diameter d in inches of a rope required to lift a weight of w tons is given by the function d = 10w/ π . How much weight can
Ilia_Sergeevich [38]

Answer:

Option D) 1.26 tons

Step-by-step explanation:

we have

d=\frac{10w}{\pi}

where

d is the diameter of a rope in inches

w is the weight in tons

we have

d=2(2)=4\ in ----> the diameter is two times the radius

substitute the value of d and solve for w

4=\frac{10w}{\pi}

w=\frac{4\pi}{10}=0.4\pi\ tons

assume

\pi =3.14

0.4(3.14)=1.26\ tons
