Three years ago, Claire borrowed money from her father to pay for a class trip. She agreed to pay 6% simple annual interest on t

Nadya [2.5K]

Answer:

Claire borrowed $500 from her father.

Step-by-step explanation:

Interest = $90

p = ?

r = 6% or 0.06

t = 3

Simple interest formula is :

$I=p\times r\times t$

Putting values in formula we get;

$90=p\times0.06\times3$

$90=0.18p$

p = $500

Hence, Claire borrowed $500 from her father.

Step-by-step explanation:

Number 1

180° = x + 70° + 55° + 30°

180° = x + 155°

x = 180° - 155°

x = 25°

Number 2

x° = 93°

y° = 47°

z° = 180° - 47° - 93°

z° = 180° - 140°

z° = 40°
