A loan of $4,000 was repaid at the end of 19 months with a check for $4,270. What annual simple interest rate was charged?

The rate of interest is 4.3%.

Step-by-step explanation:

Given,

Principal (P) = $4000

Amount (A) = P+I = $4270

Time(T) = 19 months = years

Interest(I) = $4270-4000 = $270

To find the rate of interest.

Formula

I =

so,

R =

R =

= 4.26% = 4.3% (approx)

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
