Elis [28]

Answer:

$4785.68

Step-by-step explanation:

Original amount: $4230

Interest for 1 year: 4.2%

First year;

$4230 + (4230 \times \frac{4.2}{100}) \\ = 4230 + 177.66 \\ = 4407.66$

Second year;

$4407.66 + (4407.66 \times \frac{4.2}{100} ) \\ = 4407.66 + 185.12172 \\ = 4592.78172$

Third year (total balance after 3 years);

$4592.78172 + (4592.78172 \times \frac{4.2}{100} ) \\ = 4592.78172 + 192.89683224 \\ =4785.67855224$

Round the number;

$4785.68

Pls help it due ASAP and show workings

Effectus [21]

Answer:

it's 70°

Step-by-step explanation:

well first by vertical angles we know that

$\angle BAC = \angle DAE\\\\\angle DAE = 4x+6$ ( I don't know how to put the symbol xd)

and given we know that

$\angle EAF = \angle EAD = 4x+6$

solving for x

we know that

$\angle CAD = 180\\\\\angle CAB + \angle ABD = 180\\\\4x+6+6x+14=180\\\\10x+20=180\\\\10x=160\\\\x=16$

and now for $\angle EAF$

$\angle EAF = 4x+6\\\\\angle EAF = 4(16)+6\\\\\angle EAF = 64+6\\\\\angle EAF = 70$

An angle measures 56° more than the measure of its supplementary angle. What is the measure of each angle?

ludmilkaskok [199]

Answer:

62,118

Step-by-step explanation:

Let one angle = x

So, other angle = x +56

x +x +56 = 180 {Combine like terms}

2x + 5 6 = 180 {Subtract 56 form both sides}

2x = 180 - 56

2x = 124 {Divide both sides by 2}

x = 124/2

x = 62

Other angle = 62 + 56 = 118
