$5000 was invested into an investment that pays 4.25% simple interest. The total value of the investment amounted to $6593.75. H
Basile [38]

Answer:

7.5 years

Step-by-step explanation:

P = $5000,

R = 4.25%,

A = $6593.75,

N =?

SI = A - P = 6593.75 - 5000 =$1593. 75

\because \: SI = \frac{ PNR}{100} \\  \\  \therefore \: 1593.75 =  \frac{5000 \times N \times 4.25}{100}  \\  \\  \therefore \: 1593.75 \times 100 = 21,250 \times N \\  \\ N =  \frac{159375}{21250}  \\  \\ N = 7.5 \: years \:

Find the interest due to the bank on a loan of $1000 at 7.5% for 280 days
Lera25 [3.4K]

Answer:

The interest is \$57.53

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=280/365\ years\\ P=\$1.000\\r=0.075

substitute in the formula above

I=\$1.000(0.075*280/365)

I=\$57.53

y=9x

z=3y

Step-by-step explanation:

Let

x ----> the number of cars rented during one month

y ----> the number of vans rented during one month

z ----> the number of trucks rented during one month

we know that

x+y+z=155 ----> equation A

y=9x ---> equation B

z=3y ----> equation C

Akeem and Jack are discussing their friend's new swimming pool. It is rectangular in shape. Akeem says he knows that it has a pe
schepotkina [342]

Answer:

The length of swimming pool is 10 yards.

Step-by-step explanation:

Given,

Perimeter= 90 feet

Width= 5 yards

As we have to find the length in yards, therefore, we will convert perimeter in yards also.

As we know,

1 Yard = 3 feet

Therefore,

Dividing the perimeter by 3 to convert it into yards.

90\ feet = \frac{90}{3} \ yards\\90\ feet=30\ yards

The formula of perimeter of rectangle is;

P= 2(l+w)

Putting values of perimeter and width;

30=2(l+5)\\30=2l+10\\2l=30-10\\2l=20\\l=\frac{20}{2} \\l=10

The length of swimming pool is 10 yards.
