Find the annual interest rate. $I=\$160$ , $P=\$2000$ , $t=8$ months The annual interest rate is %.
Sedaia [141]

Answer:

1\%

Step-by-step explanation:

Simple interest (I) = $160

Principal amount (P) = $2000

Time period (t) = 8 months

Let R denotes rate of interest.

Relation between simple interest, principal amount, time and rate of interest  is given by I=\frac{PRT}{100}

160=\frac{2000(R)(8)}{100} \\\\160=160R\\R=1\%

Answer:

  A.  Simon's unit rate is 2 more miles per hour than Eric's unit rate

Step-by-step explanation:

We are concerned with the number of miles each runs in 1 hour.

For Eric, that means x=1 in his equation, so his mileage is ...

  y = 6×1 = 6 . . . . miles

__

For Simon, it means we want to find time = 1 hour on the horizontal axis at the bottom of the graph. Then we want to see where the graphed line crosses that vertical line. The point of crossing has horizontal line that goes over to 8 on the vertical distance axis. That is, Simon runs 8 miles in 1 hour.

__

Eric's unit rate (miles in 1 hour) is 6 miles per hour.

Simon's unit rate (miles in 1 hour) is 8 miles per hour.

Simon's unit rate is 2 more miles per hour than Eric's unit rate.

The length of a rectangle 8 more than the width .the area is 513 square inches .find the length and width of the rectangle
Pani-rosa [81]

Answer:

width =19 inches

length= 27 inches

Step-by-step explanation:

Let width be w inches so according to given scenario as length is 8 more than width so the equation becomes

l=8+w inches (Equation 1)

Area of Rectangle= L*w

Area= 513

L*w=513    (Equation 2)

Putting l's value from equation 1 in equation 2

(8+w)w=513

w^2+8w-513=0

Making Factors

w^2+27w-19w-513=0

w(w+27)-19(w+27)=0

(w-19)(w+27)=0

w=19, w=-27

as width cannot be negative so if we only consider w=19 then

l=8+19

l=27
