Anarel [89]

For this type of question, we have to take out the percentage of each candidate:

For Arthur

85 from 95

Convert 95 to 100

That means that we have to add 5, do the same thing with 85. Add 5 to 85 and you get 90. That means Arthur got 90% For Miguel 64 from 76. Covert 76 to 100. That means we have to add 24. Do the same thing with 64. Add 24 + 64. It equals 88% Miguel got 88%

Which number comes next in this series? 1/64, 1/32, 1/16, 1/8, 1/4, 1/2, ?

alexgriva [62]

This is a geometric sequence, with the first term: 1/64

The common ratio is found through the ratio of the first two terms and the second and third term.
$\frac{\frac{1}{32}}{\frac{1}{64}} = \frac{\frac{1}{16}}{\frac{1}{32}}$
$\frac{1}{32} \cdot 64 = \frac{1}{16} \cdot 32$

Since there is a common difference of 2, we can generalise this sequence to find the nth term:
$T_n = ar^{n-1}$
a is the first term, r is the common ratio, and n is the nth term in the sequence.

$T_n = \frac{1}{64} \cdot 2^{n-1}$
Substituting n = 7, we get:
$T_7 = \frac{1}{64} \cdot 2^{7 - 1}$
$T_7 = \frac{1}{64} \cdot 64$
$T_7 = \frac{64}{64} = 1$

Thus, the next term in the sequence is 1.

sergey [27]

Answer:

The total cost is $345

Step-by-step explanation:

Zoe purchased a barbecue grill originally priced at $600

Discount % = 50%

So, cost after discount = $600-50\%(600)$

Cost after discount =300

Sales tax in Fairfax is 15%

So, cost including tax = 300+0.15(300)

Cost including tax = 345

Hence The total cost is $345
