Answer:

$840

Step-by-step explanation:

Callies family spends an average of $70 per month electric. At that rate what can that family expect to pay electric for 1 year

Note that:

1 year = 12 months.

Hence, if:

1 month = $70

12 months = $x

Cross Multiply

$x = 12 × $70

$x = $840

Therefore, the amount that family can expect to pay in 1 year(12 month) for electric = $840

padilas [110]

Answer:

$A= \frac{4}{3 + \sqrt{5} } - \frac{8}{1 + \sqrt{5} } + \frac{15}{ \sqrt{5} }$

$= \frac{4(3 - \sqrt{5)} }{4} - \frac{8(1 - \sqrt{5} }{ - 4} + \frac{15 \sqrt{5} }{5} = 3 - \sqrt{5 + 2 - 2 \sqrt{5 + 3 \sqrt{5 = 5} } }$

Pablo simplified the expression (2 Superscript negative 4 Baseline) Superscript negative 2 as shown.

Lady_Fox [76]

Answer:

<h3>He should have found 8 as the exponent, not –8.</h3>

Step-by-step explanation:

Given the expression simplified by Pablo as $(2^{-4})^{-2}$

On simplification we have;

According to one of the law of indices $(a^{m})^{n} = a^{mn}$

Applying this law to the question will give;

$(2^{-4})^{-2}\\=2^{-4*-2} \\\= 2^{8}$

Based on the calculation above, the exponent of 2 is 8 which means that Pablo should have found 8 as the exponent, not –8.
