galben [10]

Answer:

$t \leq 18.67\ years$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\ years\\ P=\$4,500\\ A=\$7,020\\r=0.03$

The inequality that represented this situation is

$P(1+rt) \leq A$

substitute the values and solve for t

$4,500(1+0.03t) \leq 7,020$

$(0.03t) \leq (7,020/4,500)-1$

$t \leq [(7,020/4,500)-1]/0.03$

$t \leq 18.67\ years$

Based on the diagram below, what is the measure of arc DC?

Debora [2.8K]

Answer:

108 °

Step-by-step explanation:

∠DOC = 180° - 112° = 68°

∠DOC = 1/2(arc AB + arc DC)

68 = 1/2(y + 80 + y)

68 = y + 40

y = 28

arc dc = 80 + 28 = 108 °
