Joe borrowed $3,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 4 years?

$1050

Step-by-step explanation:

Simple interest =P*R*T/100,

substituting the values:

3000*7*5/100= 1050.

therefore Simple interest = $1050

Hope it helps

450

step-by-step explanation:

you get texts and minutes, so why not

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
