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.

What is the measure of angle B in the figure below?<br> о 30°<br> О 45°<br> О 60°<br> O90°

Slav-nsk [51]

Answer:

45°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosB = $\frac{adjacent}{hypotenuse}$ = $\frac{3}{3\sqrt{2} }$ = $\frac{1}{\sqrt{2} }$ , hence

B = $cos^{-1}$ ( $\frac{1}{\sqrt{2} }$ ) = 45°

Find the value of X. I can't figure out what to do when one is at a right angle.

AnnyKZ [126]

Answer:

x = 20

Step-by-step explanation:

Two lines are parallel. So, alternate interior angles are congruent.

x +8 + 6x - 58 = 90

7x - 50 = 90

7x = 90 +50

7x = 140

x = 140/7

x = 20
